png cropping
I'm LilyPonding a piece which requires a "Notation Key". The recipient
of this notation key will be doing a bit of further manipulation of the
output. What I need to provide is, at her preference, a PNG closely
cropped so that she can then position this graphic under some
introductory text about the piece. I have been unsuccessful at finding
information about this in the docs. I've checked the command-line
options section and elsewhere but have not found any reference to
controlling the cropping.
The notation key follows at the end here if anyone wants to see how I've
done this. I'm not 100% pleased with the spacing but haven't yet tried
to adjust it yet. Suggestions for cropping the output are mostly what
I'm after, but suggestions for a better way to make the notation key are
also welcome.
A couple of ideas that I haven't yet explored involve trying
lilypond-book or OpenOffice with LilyPondTool.

Png cropping
I read in the documentation that it is possible to create a cropped png by
using "-dbackend=eps -dresolution=600 —png" and inserting this \paper block:
\paper{
indent=0\mm
line-width=120\mm
oddHeaderMarkup = ##f
evenHeaderMarkup = ##f
oddFooterMarkup = ##f
evenFooterMarkup = ##f
}
However, I think the cropping is too heavy. How can I produce a png with some
nonzero margins? I've tried to add top-margin, bottom-margin,
top-system-spacing, last-bottom-spacing, left-margin, right-margin,
paper-width, but none of them seem to work.
Thanks a lot in advance,
Renato

(that's what I use) The info in AU about lilypond-book might help (inserting lilypond output into other program), but probably won't, since it's aimed at producing eps images. Actually, you might be able to convert the eps to png using an external program. Finally, you could play with clip-example, which I believe is now in NR 3. But I'm not certain if anybody's rewritten the docs for them -- I certainly haven't.

Re: png cropping
This is an old thread but I found it in my email box and thought I'd respond because I've recently written a script to handle this sort of thing. I share with some trepidation since last time I shared a script, someone pointed out to me that there was already a lilypond command-line option that performed exactly the same thing :) Ok so this script requires the "netpbm" package of image manipulation programs. Anyone who builds Lilypond from source probably has it already, but it's easy to get under Linux and Mac. for Ubuntu I do "sudo apt-get install netpbm" and for mac "sudo port install netpbm". I see that there's a Windows version but I've never tried to install that because I rarely use Windows. So far the script works perfectly for Linux and Mac OSX 10.4 (maybe 10.5 but I can't try it b/c I don't have one). A couple of lines are different in the Mac version because of the different image viewer and different way of invoking lilypond at the command line. What I find useful about the script is that it prompts the user for the desired output resolution and format. So far I've run it successfully at resolutions from 72 to 1200 dpi in png, jpeg, and tiff formats. I suppose you could use any image format for which there is a "pnmto___" program, substituting the appropriate text for the format. The script will look for whatever format you type in there. Note, if you want a musical example suitable for inserting in a word-processed doc or web page, you might want to remove or comment out the header block of your file. Once you've saved and made the file executable (I keep it in my /bin directory so it's in my $PATH), just do "lilyimage foobar.ly" and enter the resolution and format when prompted.

Re: png cropping
I'm guessing that one of the netpbm tools will handle transparency, it's just a matter of figuring out which one. Didn't this come up on a recent thread? I seem to remember trying it out on something and getting a transparent background. When I get some time later I'll look into it. It would be simple enough to add a prompt asking if you'd like a transparent background, I guess. Re: the footers: are you talking about the "engraving by Lilypond" footer or some other thing? In the examples I've run with this, there have been no footers, but I've only been doing my own files.

Re: png cropping
Ok I rewrote it a bit to allow for transparent background and I think it works nicely. I changed it to ask whether the user wants a transparent background right after entering the output resolution. If transparent = yes, then it does not prompt for an output format but instead uses png by default. (It would be easy enough to add a prompt inside the if -- fi construct asking whether the transparent format should be png or gif, I guess.) If transparent = no, then it asks what the final image format should be and then continues normally and outputs jpeg, tiff, or png.

Re: png cropping
Here's a modified version of Jonathan's unix/linux script that supports
arguments which are:
-t or --transparency : output format forced to png and you get
transparency
-r=N or --resolution==N : (example -r=72) set resolution
-f=FORMAT or --format=FORMAT : (example -f=jpeg) set output format
So, if the script is named lilytoimage, you could do:
lilytoimage -r=72 -t lilydir/myfile.ly
or
lilytoimage -r=111 -f=tiff lilydir/myfile.ly
If you don't specify any of those arguments then it works just like it
did before, except it will also ask about transparency. I don't have a
Mac to test on, so I didn't mess with the Mac version. Let me know if
there's any bugs;)

Re: png cropping
This looks really great but it failed when I tried to run it. I must have messed it up when copying it over to my editor. Would you mind attaching a working copy as a file instead of copying into the email? Also, I think we crossed paths in our most recent posts about this. I sent a revised version that allowed for a choice between gif and png on transparent images and also fixed a problem I had introduced related to tiff format. I'll attach most recent script. I really like the flexibility your modifications introduce, being able to bypass all the prompts. I like the prompts for myself because I have a hard time remembering flag arguments sometimes, but even I can probably remember these. Besides that I can use your modifications to learn some tricks about scripting--clearly you actually *know* how to script! I'm a total newb but am having fun learning. :) Jon Patrick Horgan wrote: Here's a modified version of Jonathan's unix/linux script that supports arguments which are: -t or --transparency : output format forced to png and you get transparency -r=N or --resolution==N : (example -r=72) set resolution -f=FORMAT or --format=FORMAT : (example -f=jpeg) set output format So, if the script is named lilytoimage, you could do: lilytoimage -r=72 -t lilydir/myfile.ly or lilytoimage -r=111 -f=tiff lilydir/myfile.ly If you don't specify any of those arguments then it works just like it did before, except it will also ask about transparency.

Re: png cropping
Patrick, Sorry to keep posting new versions but I found another problem with my previous one, which is that there's no ppmtopng command, so I had to add another if-then statement to fix it. I also learned a couple of things from your script that are very useful (e.g. accepting equally "yes," "Y" or "y") and changed the prompt to a more usual style: from (yes/no) to (y/N). I've now tried all variations and they all work. Now if you can integrate your mods to accept arguments at the command line that'd be sweet.

Jonathan, on my system there's no ppmtopng or ppmtotiff and ppmtojpeg
is a link to pnmtojpeg. This is with Hardy Ubuntu and a fresh install
of the utils. Annoying, no? It makes the changes to your script break
on my machine.
I've found that creating symbolic links in /usr/bin like:
ln -s pnmtopng ppmtopng
ln -s pnmtotiff ppmtotiff
fixes the problem, but why wouldn't that have been done automagically?
I removed the netpbm package and it didn't remove my links, so they're
really not part of the package. Maybe I should file a bug against the
package. It does reinstall the link from ppmtojpeg to pnmtojpeg when I
reinstall it. How is it set up on your system?
It seems like to be bulletproof, the script needs to check and see
which of ppmto$FORMAT and pnmto$FORMAT exists and use that, that's easy
to do with which, it already has all the code to look through your PATH.
I'm attaching a new version of my version of your script with that
change and a new routine, getval, that validates input, you use it
like:
prompt= "Enter desired output format (jpeg, png, tiff, gif, pcx, bmp): "
goodvals=("jpeg" "png" "tiff" "gif" "pcx" "bmp")
getval
FORMAT=$outval
If the user enters something that's not on the goodvals list, for
example joe, it reprompts them after telling them what they might have
entered:
Enter desired output format (jpeg, png, tiff, gif, pcx, bmp): joe
Expecting one of : jpeg png tiff gif pcx bmp
Enter desired output format (jpeg, png, tiff, gif, pcx, bmp):
Cool, no? I suppose I should add validation to the command line
arguments as well.
Ok, just did that, resolution checked for numeric both on input and
from the command line, format checked for one of the allowable things,
and check to make sure there's a filename, and print meaningful error
message and a usage statement. Try it and see if it works for you.
I'm almost tempted to check for all the pnmto and ppmto and
automatically build the list of allowed types instead of hard coding
them--nah, I'll leave that as an exercise for the reader;) It really
needs to be done with my version because I only let people use what's
on the list:( Yours will just work as long as it's a valid format.
You could grab the outcmd part of my version of your script. It
automagically picks either ppmto or pnmto and exits with an error if
neither are found.
I also check for the existence of pnmtojpeg and abort the script if
not found with
a message that the netpbm utilities have to be installed to use the
script.
Now the script is much larger because of all the checking.

Re: png cropping
Cool, Patrick! Your scripting skills are admirable! The only thing
that worked unlike I expected was when I was asked if I wanted
transparency, I simply hit "enter," thinking it would default to "no"
because the N was capitalized, and it prompted me again saying
"expecting one of these values..." On my script the enter button worked
for "no." Not a big deal.
The way I dealt with the lack of ppmtopng or ppmtotiff was to add
another "if" statement that called on pnmtopng or pnmtotiff if either
png or tiff were chosen for the output format. Probably not very
elegant or flexible, but the only way I know how to deal with it at the
moment. Did you see the latest version? I think you were commenting on
an earlier version that was broken with png and tiff. It's hard to keep
track when I keep posting so many :)
I'm going to study your script carefully when I have more time tonight
and try it with the command-line options and stuff. It's shaping up to
be a very useful tool, at least for me :) Thanks for being so interested
in it and scripting all these cool features that I don't know how to do.

Re: png cropping
Hi Patrick,
I've been running your script trying to use the command-line arguments,
and something's happening with the format argument. I specify it with
an argument, but then I still get prompted for format. I might not be
doing the flag right. I've tried it with -f=jpeg, -f=JPEG, -fJPEG, and
I think that's it. I'll copy the terminal output below so you can see.
On this example I use -fGIF and while it doesn't make the script fail,
it does still ask me for a format. Am I specifying the format wrong?
BTW, in the script I attached to the last email, you'll notice that with
transparent background you have a choice between either png or gif--it's
not forced to png. Is there a way to work this option into your version?

Cool, no? I suppose I should add validation to the command line arguments as
well.
Ok, just did that, resolution checked for numeric both on input and from the
command line, format checked for one of the allowable things, and check to make
sure there's a filename, and print meaningful error message and a usage
statement. Try it and see if it works for you.

Re: png cropping
Alright, this is probably my last version. It now checks the input
for format against all the available conversions (found by looking for
all the programs in the filesystem that start with ppmto and pnmto) and
if you didn't pick one, gives you all the choices!
Enter desired output format (jpeg, png, tiff, gif, pcx, bmp) ... : fooburger
Expecting one of : acad bmp ddif eyuv fiasco fits gif icr ilbm jpeg
leaf lj lss16 map
mitsu mpeg neo palm pcx pgm pi1 pict pj plainpnm png ps puzz rast
rgb3 rle sgi sir
sixel tga tiff tiffcmyk uil winicon xpm xwd yuv yuvsplit
Enter desired output format (jpeg, png, tiff, gif, pcx, bmp) ... : tiffcmyk
Of course if you pick one that eog doesn't know how to display it
will complain. If you pick one that requires extra command line
argument, it will complain. If you comment out the line that removes ps
and select ps as the format type, then look at the resultant postscript
file with a postscript viewer, it's rotated 90 degrees! Cool:) That
looks like a bug in pnmtops. It's a shame that pnmtotiff doesn't have a
-transparent argument since tiff supports transparency.
I also fixed a problem where the validation routines would go crazy
if you just hit enter when prompted for input. Also made it not prompt
for transparency if you already specified a format on the command line
that doesn't support it, and conversely if you asked for transparency on
the command line and specified a format that doesn't support it, notes
your user error and asks you to pick gif or png.
Thanks for inspiring me Jonathan. I'd like to make clear that all
of this script that does any useful work is Jonathan's original script.
My parts just validate input and add command line arguments. I've
developed some general purpose routines for this script that I've wished
to have for a long time and will reuse often.:)
I can't believe I spent most of my day on this !

Hi Patrick,
I've been running your script trying to use the command-line
arguments, and something's happening with the format argument. I
specify it with an argument, but then I still get prompted for
format. I might not be doing the flag right. I've tried it with
-f=jpeg, -f=JPEG, -fJPEG, and I think that's it. I'll copy the
terminal output below so you can see. On this example I use -fGIF and
while it doesn't make the script fail, it does still ask me for a
format. Am I specifying the format wrong?
it would have to be the same as the input from the command line, i.e.
-f=jpeg or -f=gif---I don't have a clue why it would fail, though with
our weird crossing of versions I don't know which version you're using.
I put a version in this one, and if you specify -v it will tell you the
version and quit. I fixed the defaults as you asked, and put in
defaults for N 72 and png, (and if they pick transparency a default of
png as well). If the command line args still don't work please let me
know. They work here. My experience is that whenever I'm sure I've
tested everything there are still many bugs, so please let me know:)
BTW, in the script I attached to the last email, you'll notice that
with transparent background you have a choice between either png or
gif--it's not forced to png. Is there a way to work this option into
your version?
Yep, fixed.

Re: png cropping
Patrick! It's all working beautifully now. I've tried about 10 different configurations of options using both the flags and the prompts, and everything worked just as expected. This is a really great tool! I like being able to use either the command-line arguments or the prompts. The arguments are especially useful if you just want to run exactly the same process again after editing the lilypond file, because you can just hit the up arrow to get the previous command and not have to go through all the prompts again. I also like the prompts because sometimes I forget the command-line options. But then you've added the usage thing, too. And now a version number 1.1! I never dreamed I'd contribute code to something with a version number ;-) I think we've officially beat this thread to death and now have a nice script to show for it. Thanks for the collaboration! It's the most fun I've had in a while. Now if I can just get my head around the code you wrote I'll be doing something... Best, Jonathan p.s. now that we have a tool with a version number, I might try learning how to write a brief manpage for it. Good idea?

Re: png cropping
This is a good idea. I tried it and it behaves exactly the same as before. I had wondered about this, not with respect to the different file formats, but with different desktop environments. I imagine eog wouldn't behave properly in KDE, for example. Does xdg-open work for KDE? Or does that little g stand for gnome still? The next thing I want to do with the script is make it check to see whether the user is running Linux or Mac OSX and execute the proper command. I should also make a condition for different desktop environments I guess.

I must say that you are most awesomely cool. How wonderful to find

... much cool stuff elided...
p.s. now
that we have a tool with a version number, I might try learning how to

A most excellent idea! manedit is your friend. Complete wysiwyg man
editor. Its help has a complete and easy tutorial. On ubuntu it's
just sudo apt-get install manedit. Since
you're doing that I'm adding a -a (about) with your name and mine, some
more comments so others can modify it more easily, and will call it
version 1.1.1. I also added a -V=viewer, so I could use, for example
evince if the output format was ps. N.B. evince doesn't display
transparency so if you use it with transparent gifs or pngs you might
think the transparency gone, but it's not.
One feature it really needs is an ability to handle the situation
where the output for file.ly is for example, file-page1.png and
file-page2.png. You'd have to get a wildcard list of things that
matched $STEM*.png and loop over them to do the conversions, then
something like $viewer $STEM*.$FORMAT & at the end. That would
make it work as it currently does for most things, there'd just be one
thing in the list, but still work for the case where there's something
there. A generic wildcard is best because someone might have done a
#(define output-suffix "blablabla") and we want to support that case
too. eog will bring up all the pages and let you page up and page down
through them, and evince will bring a a window for each file. There's
enough examples in the script so that you could figure out how to do it
if you would. We could call it 1.1.2;) If you don't have time let me
know and I'll get to it sometime. If you do, change the version in the
script, add to the changelog at the top and send me a copy:) Maybe we
could donate it to the lilypond project.

I didn't know about that:) I just tried it with -V=xdg-open with a ps
output and a png output and it used evince and eog respectively
automagically;) I changed it so that it sets its default viewer
dynamically from a list, looking for xdg-open, and if not found, eog,
and if not found evince, and if still not found, at the end politely
tells you that it didn't find a viewer and is only generating output.
That makes 1.1.1.1 a very minor release since it didn't change anything
visible to the user;)

Re: png cropping
Ok I've caught on to your version-control comments at the top and have
started adding to them. This time I added two things to the script:
1) recognition of the computer's OS (only Linux or Mac at this point),
and appropriate changes to the commands to accommodate. After this
change, the script works exactly the same (from user's perspective) on
both my Ubuntu and Mac OSX 10.4 systems :) I used to have to keep
separate versions of the script for each one.
2) added a "known issue" comment that the script doesn't handle spaces
in directory names. It fails at line 43 (cd $currentdir) if the
directory of the lilypond source file has a space in the name.

Yes. I haven't thought much about multiple-page documents yet because
for me the object of the script is to produce small images of musical
examples to use in a research paper or on a website. Are there
situations where you want multiple-page examples with whitespace cropped
like this? I could see where it'd be nice to make a longer document's
background transparent. It's certainly worth a try to deal with a
longer file. The more flexible the script is, the better, after all.
I'll poke around with it this weekend, perhaps.
Most recent version attached.

Re: png cropping
I've been following this, and just tested the latest version on OSX... quite nice guys! Perhaps the -V flag can be set to not open the image after it is done? This utility will be great for mass creating images (as most command line tools are), but having Preview open each one up will get very tiring... perhaps if the is no -V passed in, that step can be skipped?

Hats off to you. Working on this script is making me understand the genius of the Unix model. Someone with no programming experience like me can make something that gets a job done using a bunch of tiny tools. Really fun! ... much cool stuff elided... p.s. now that we have a tool with a version number, I might try learning how to write a brief manpage for it. Good idea? A most excellent idea! manedit is your friend. Complete wysiwyg man editor. Its help has a complete and easy tutorial. On ubuntu it's just *sudo apt-get install manedit*. Since you're doing that I'm adding a -a (about) with your name and mine, some more comments so others can modify it more easily, and will call it version 1.1.1. I also added a -V=viewer, so I could use, for example evince if the output format was ps. N.B. evince doesn't display transparency so if you use it with transparent gifs or pngs you might think the transparency gone, but it's not. Cool. I'll try this after the kids are in bed tonight. One feature it really needs is an ability to handle the situation where the output for file.ly is for example, file- page1.png and file-page2.png. You'd have to get a wildcard list of things that matched $STEM*.png and loop over them to do the conversions, then something like $viewer $STEM*.$FORMAT & at the end. That would make it work as it currently does for most things, there'd just be one thing in the list, but still work for the case where there's something there. A generic wildcard is best because someone might have done a #(define output-suffix "blablabla") and we want to support that case too. eog will bring up all the pages and let you page up and page down through them, and evince will bring a a window for each file. There's enough examples in the script so that you could figure out how to do it if you would. We could call it 1.1.2;) If you don't have time let me know and I'll get to it sometime. If you do, change the version in the script, add to the changelog at the top and send me a copy:) Maybe we could donate it to the lilypond project. Patrick Yes. I haven't thought much about multiple-page documents yet because for me the object of the script is to produce small images of musical examples to use in a research paper or on a website. Are there situations where you want multiple-page examples with whitespace cropped like this? I could see where it'd be nice to make a longer document's background transparent. It's certainly worth a try to deal with a longer file. The more flexible the script is, the better, after all. I'll poke around with it this weekend, perhaps. Most recent version attached.

Re: png cropping
After much revision, addition, and general fussing about with it, I'm
happy to post the official version of what we're calling "lily2image," a
script for converting lilypond source files to cropped image files in
many different formats suitable for insertion into documents (theses,
research papers, etc) or web pages. This works equally on Mac and
Linux, but not on Windows. Dependency: netpbm (available in Linux repos
and MacPorts)
Many, many thanks to Patrick Horgan for all of his work on this. He
added tons of code and gave me excellent guidance as I was learning how
to script. This was a great learning experience.
Thanks also to Josh Parmenter, who jumped in somewhere along the way and
made very helpful suggestions, and also tested every revision I sent
him. Thanks for a fun project, guys! I hope others in the Lilypond
community will find it a useful tool.
Jon
p.s. I've also attached my manpage for the script: lily2image.1. Just
put it somewhere in your manpath and make sure it has read permissions
for all users. I put it here on Linux:
/usr/share/man/man1/lily2image.1
It was slightly different on Mac but now I can't remember. If someone
needs help I'll check on it.

Re: png cropping
If you are familiar with scripting, and have Windows, use it as a template. But my guess is you will need to find different utilities to do the conversion and cropping. This is pretty straight-forward to do, since most of these utilities run just fine on linux and mac (though most scripts check for the system that is running, and make adjustments as needed). The hard work I would say is done (great job Jonathan and Patrick!). There is no reason you couldn't use this script as a template and make something similar for Windows. I know Jonathan used this project as an impetus to learn how to script... rather then just complaining, perhaps you can do the same.

I couldn't even figure out how to run Lilypond from the Cygwin prompt, and the script pretty much relies on being able to do that :) There's probably a way to make it work, but I didn't see the point since everything already worked perfectly on the Unix-based systems, which are the only ones I use. It would take someone who really knows Windows to adapt lily2image to work on it. I would welcome it because I think it's an extremely useful tool and it's a shame that Windows users can't take advantage of it. Patrick, you mentioned at some point along the way that it would have been better if I had started the whole thing in Python instead of bash. Would this also have made it easier to port to Windows?

Hi, Thank you for your answers. I am actually programming something automated (a Telegram bot for LilyPond!

LilyPond is a very powerful tool, because volunteers have invested their time and abilities to create solutions for what use cases they saw coming. IIUC, the PNG cropping has been designed for use with lilypond-book, at any rate the developers didn’t see any need for adjusting the margins. If you want to change it, you are very welcome to propose patches, or file a concise enhancement request with bug-lilyp...@gnu.org. Certainly there are many (seemingly) small features missing from LilyPond’s toolset, but that’s no reason for any kind of accusations. Try rephrasing the sentence as ‘Wouldn’t it be great if there were some possibility to adjust margins with the PNG cropping mechanism?’ – that sounds a lot more appropriate.

IMO that would be like going to the tile store and having to buy tiles with 3mm of grout round them. One buys clean tiles and applies grout of desired width when they're laid. In my workflow, I don't use PNGs because they're already rasterised, which messes up rescaling. PDFs are much better, and there's a tool for cropping them, pdfcrop, which is bundled in the TeX Live distribution, which LilyPond users are likely to be already using: $ pdfcrop --margins in.pdf out.pdf Adding facilities to LP for manipulating PNGs would be a big duplication of time and effort IMO. After all, where do you stop? $ gm convert -negate -trim -bordercolor red -border 10x0 -bordercolor green -border 0x8 in.png out.png looks like an over-the-top command you might use. It will convert the image to white on black, trim it (by inspecting the colour of the corner pixels), then add coloured borders to the sides and the top and bottom. Just prune that command to taste.

Re: Png cropping
Hi Simon, hi David, I am very sorry. I absolutely did not intend to make any sort of accusation. I did word the phrase badly, led by the too impulsive thought that I couldn't believe that LilyPond, even being so powerful, couldn't do what I thought it would be certainly able to do. Actually, after reading your replies, I realised why this behaviour is actually intended and indeed much more rational than giving the option of cropping the png as the user wants. I will surely follow your suggestions of adding margins to the cropped png, instead of trying to crop the full one. Thank you for your replies.

Re: Png cropping
Hi, Thank you for your replies. Using a GUI like Frescobaldi is not really something I can do while programming. However, I can surely insert margins to the cropped png, which is definitely what I am going to do.
