[Gimp-user] Problems with generated transparencies

[Joerg Bergmann]

I use the actual Fedora 11 version of GIMP.

I have problems while generating partially transparency in images.
I have an image containing white background and some light-blue,
unsaturated details. I do the following steps:
1. Add transparency
2. color (white) to transparency
3. transparency threshold
1+2 seem to go OK, but step 3 makes the blue colors fully-saturated
plus very dark. At the moment, I did this task using gifsicle, GIMP
seems to be unusable for that. Any hints?

So the next update will see the ability to revert back to the old
behavior? That will be nice. (:

You don't have to like single image node either. It'll be optional.

Really?

I absolutely /hate/ the single window mode. I loved being able to float
toolboxes and have the image editing area closable separate of the main
program when I'm not using it (but will go back to using GIMP soon).
It's one of the features (aside from being free) that first attracted me
to The GIMP. Losing that flexibility is a pain in my rear.

I generally give GIMP it's own desktop. Solves that problem rather well.

I agree completely, but.  The failure is not from posting below, but from
not trimming irrelevant information when posting.  If *only* that which
is required to put your post into context is quoted, the problem is gone.

Some small degree of intelligence *is* required when carrying on a
conversation along with some consideration.  Bottom posting is not set in
concrete, it is often better to intermix comments and quoting as above.
And, if my answers had appeared above rather than intermixed, the
substance of my comments would not be as clear.

It is much more considerate to compose your answers in a manner to impose
as little as possible on your intended audience than to make him wade
thru a lot of trash to try and determine your meaning and to possible
mis-understand it completely.

I don't know anything about DPP, but my favourite sharpening filter
lately for Gimp is Smartsharp. I like its results even better than
Smart Sharpne in Photoshop CS2. I don't think it's included as part of
the default Gimp package, I need to add it separately in openSUSE
11.2.

There are several plugins and scripts to improve sharpness. The best for 
me is Unsharp mask2 (I use almost only the 3 first parameters). No more 
developped but I hope it works with future versions of Gimp.

Not sure what Kompozer is, but I suggest you will probably need to do
some hand coding

 Open up you .map file in a text editor.
 have a read and see what it does
 remove the comments if you wish

 Now open up your web page in the text editor
 copy and paste your .map file into the web page file where you want it

That's where judicious snipping of previous emails and replying directly
underneath the points your addressing is ideal.


Top-posting = bad and goes against the way you read (and sorry, while I
do read every email in a topic I'm following, I don't remember what was
said from one day to the next). Bottom-posting isn't much better, but it
follows the NORMAL flow of reading. Email is just like any other
text-based communication.

Last time I'm posting on the subject. Lets go help some folks.

[Gimp-user] Sharpness Values GIMP vs DPP

[Adam]

Hi, new to the list and have used GIMP for a couple of years. Mostly doing 
things that I could not do in Canon's DPP(Digital Photo Pro). In windows this 
worked real well for me. 

Now I have switched to Ubuntu and I am trying to get away from using DPP. One 
setting I used in DPP was the sharpness on the JPG side of the RAW conversion 
(second tab on the toolbox). I would mostly crank it up to around 450-500. 

My question would be, what is that equivalent to in GIMP. In DPP it was one 
slider, GIMP there seems to be a few options. If there is an archive to point 
me too that would be perfect.

This is a common misconception. The single-window mode is just as much 
for Linux users as it is for Windows users. It is in many ways my own 
itch I am scratching: I run Linux but hate to manage windows and/or 
workspaces, and single-window mode will fix this for me.

I always try to adhere to nettiquette standards, so I will try not to
top-post. But I always completely disagree with the reasons given for it.
Of course, if someone reads a complete thread at once, the argument
given mostly is correct: you read the original post first, and the
following posts after that in sequence. So than top-posting makes clumsy
reading indeed.
But that' s not how at least *I* read messages on the many mailing lists
I follow. When new postings to an existing thread arrive in my mailbox,
I have read the postings prior to that post already earlier, so I don' t
have to read them again. For me, scrolling down all the previous
postings is a waste of time and energy. And frustrating, to be honest...
Same goes for snail mail: all the letters that came in yesterday and
before are on a stack already, and the new letters that come in today go
on top of that.
So not for every single human on the planet top-posting breaks the
normal reading behaviour (unless, of course, I'm not considered a human
being on this planet :-))
Again, I will adhere to nettiquette, but I felt I should give some
counter-arguments.

By the way, the GIMP is a great program!

[Gimp-user] two bizarre problems

[Olivier Lecarme]

Dear GIMP users and developers,

I'm encountering two weird problems with GIMP recently. What is weird is
that it's not the same on two different but similar computers, running
the same versions of GIMP (2.6 or git 2.7) on the same version of Debian
GNU/Linux (testing).

1. Any dialog like the ones obtained with most filters should contain
small icons in the bottom buttons (Help, Reset, Cancel, and OK). This is
the case on computer A, but not on computer B. This is consistent across
all the dialogs.

2. The gtkam-gimp package is installed on both computers. There are two
entries dealing with the camera in the Image: File -> Create menu on
computer A, but none on computer B.

I did not yet discover any other difference, but maybe somebody could
suggest me to explore some other parts. Of course I can make any
additional suggested test for debugging this problem, which most
probably comes from my installation on computer B, and not from GIMP
itself.

Thanks in advance for any suggestion.

Here is a table that provides an approximate mapping between Photoshop

Sure; subsampling takes groups of 4 x 4 pixels and averages the values
for hue/lightness for 2 x 2 pixels, or all four pixels respectively.

4 x 4 x 4 retains the original data, 4 x 2 x 2 averages for two groups
of 2 pixels each, and 4 x 1 x 1 assigns the same value to all four pixels in
the group , which results in a smaller file, but loss of quality at the same
time. (That's at least how I understood it.)

4 x 4 x 4:  4 x 2 x 2:4 x 1 x 1:

Then there' s also the DCT value (Discrete Cosinus Transformation; the
algorithm used in JPEG; I think JPG 2000 uses a Discrete Wavelet
Transformation instead, which results in better quality -> less JPG
artifacts). I have set this option to 'Fast Integer'; 'Floating Point' 
results

AFAIK in additional loss of information.

wow, i grossly underestimated the influence of the advanced parameters:

[Gimp-user] Thrashing with C2G - what to do?

[Doug]

I have a 2.4Ghz 6Gb 64-bit machine running Gimp 2.6.7 on Mandriva Linux 
2009 Spring. The Tile Cache Size is set to 5Gb.

A 31MB tiff file is converted by c2g pretty quickly.
However a 45Mb tiff converts about half the preview image quickly and 
then halts indefinitely, thrashing with the CPU 100% occupied.
I've run gimp in verbose mode on a succesful and this unsuccessful 
conversion - there's nothing obviously different in the messages, except 
that the unsuccessful conversion seems to be hung at an earlier stage.

What's up? Is it likely that c2g would saturate 5GB of memory with a 
45Mb image?
Are my adjustments wrong? Or is there some other way round this?

This has nothing to do with exporting png files. The conversion happens
when you open the file - all images in Gimp are only 8 bits per channel.

I fully agree that this is bad design.
If there are interstages of say, 8.0  8.25  8.5 and 8.75,

Hi,

I wanted to ask if it were possible to add some kind of warning to the
png export settings that pngs are only saved as 8 bit png. It is not
obvious that saving as (lossless) png causes loss when using Gimp,
because the input was 16 bit greyscale and the output ends up with 8 bit
greyscale.

I read that there is developement going on to implement 16 bit png, but
a warning till then would really help.

Thank you for your time and efforts.

Malte.
