[Matplotlib-users] pyinstall and matplotlib
Has anybody been able to create an exe of their python applications involving matplotlib using pyinstall (ver 1.3)? I am getting a: RuntimeError: Could not find the matplotlib data files when I attempt to run the exe created. In searching the web, it appears this is an issue when others tried to use py2exe as well. Unfortunately, the few hits I saw doesn't include enough details to inspire me as to what I should be doing in my pyinstall .spec file. Does anybody has an example or information about this?

Re: [Matplotlib-users] pyinstall and matplotlib
Well, looks like nobody has an answer to this question. How'bout py2exe or other ways of creating exe files out of matplotlib projects? Has anybody been able to do that? --- [EMAIL PROTECTED] wrote: > Has anybody been able to create an exe of their > python > applications involving matplotlib using pyinstall > (ver > 1.3)?

Re: [Matplotlib-users] MatPlotLib + Py2exe, backend problems ...
With Stef's help, I was able to get pass the "Matplotlib datafile not found" problem in using py2exe and Matplotlib under Python 2.3 - but then ran into the same Tkinter not loaded problem like he did. After reading Stef's messages from this list, I downloaded the latest version of Matplotlib - only to find that Python 2.3 is no longer supported. So, I loaded up Python 2.5 and ran the setup script for Py2exe. Now, py2exe is unable to find wxmsw26uh_vc.dll - eventhough I have wxPython 2.8 installed. So, I dug up a copy of wxPython 2.6 and have that installed. The file is now there but py2exe still can't find it. This is very fustrating! > Date: Mon, 18 Feb 2008 21:09:07 -0600 > From: "John Hunter" <[EMAIL PROTECTED]> > Subject: Re: [Matplotlib-users] [wxPython-users] Re: MatPlotLib + > Py2exe, backend problems ... > To: "Stef Mientki" <[EMAIL PROTECTED]> > Cc: matplotlib-users@lists.sourceforge.net > Message-ID: > <[EMAIL PROTECTED]> > Content-Type: text/plain; charset=ISO-8859-1 > > On Feb 18, 2008 1:11 PM, Stef Mientki <[EMAIL PROTECTED]> wrote: > > > What is setup.cfg, where can I find it and where can I get > information > > about it ? > > Let's keep this on matplotlib-users so we don't annoy the > good folks at the wxpython and distutils lists... > > setup.cfg is a build/configure file that ships w/ matplotlib > in recent versions (0.91.x).

Re: [Matplotlib-users] MatPlotLib + Py2exe, backend problems ...
So, do I understand this correctly: In order to get rid of the Tkinter problem when building a matplotlib application using py2exe, I need 0.91.2 ver of matplotlib and use the setup.cfg file to select the backend I want (wxpython in my case). Then run py2exe to build the ap. Correct? But then, as I posted earlier, this create a new problem for me in that py2exe says it can't find wxmsw26uh_vc.dll - even though the file exists. What I need is a version of 0.91.2 ver of matplotlib that works with Python 2.3 to see if that works, or I guess I would include Tkinter with my exe?

Re: [Matplotlib-users] MatPlotLib + Py2exe, backend problems ...
Michael, I am referring to the fact that there are no Windows binaries provided for Python 2.3. If I simply copy the matplotlib directory over to Python23, py2exe will get confused. I have no clue how to build it for Python23. I don't even have any C compiler. > -Original Message- > From: Michael Droettboom [mailto:[EMAIL PROTECTED] > Sent: Tuesday, February 19, 2008 12:19 PM > To: [EMAIL PROTECTED] > Cc: matplotlib-users@lists.sourceforge.net > Subject: Re: [Matplotlib-users] MatPlotLib + Py2exe, backend problems ... > > > [EMAIL PROTECTED] wrote: > > What I need is a version of 0.91.2 ver of matplotlib > > that works with Python 2.3 to see if that works... > > I might be misremembering, but I thought 0.91.2 worked with > Python 2.3. > I don't use 2.3 every day, however.

Re: [Matplotlib-users] MatPlotLib + Py2exe, backend problems ...
I *finally* got this to work!!! Thanks to Werner's message, I found the culpit: the matplotlibrc file copied to the dist directory contains the TkAgg backend. All I had to do is to change *that* file to say: backend : WXAgg Note that it's not the matplotlibrc in the installed copy - but the one in the resulting dist directory. In addition, I have to do a: set MATPLOTLIBDATA=.\mpl-data before I start the exe file. I don't know why this is necessary because the code for _get_data_path appears to look at that directory by default but if I don't set this, it can't find the data files. In any event, it works now - after bumping head for 2 weeks! Thanks everybody. > -Original Message- > From: Werner F.

Re: [Matplotlib-users] MatPlotLib + Py2exe, backend problems ...
Ok, I know what the problem is. I was using a sample setup.py posted by Stef and in his setup, he created a "mpl-data" subdirectory under "dist" to store all of the data files use by matplotlib. That's why matplotlib couldn't find it without a set statement. After changing the name to "matplotlibdata", everything works. I also made changes to every one of the matplotlibrc file I found in the installed copy of matplotlib to invoke WXAgg - instead of TkAgg. So for completeless, may be this will benefit other matplotlib users, here's my py2exe script - tested using python 2.3, latest wxpython and so forth. Let say you wish to create an exe of the sample multicolor.py program. Place multicolor.py in a test\multicolor directory, and a copy of the following script, have py2exe installed, and then just run it. You will end up with a dist subdirectory under test\multicolor and that's where you'll find multicolor.exe. # Kill_Distro = True MatPlotLib_Wanted = True def File_Exists( path ): res=os.path.isdir(path) if res==True: return res return os.path.isfile(path) from distutils.core import setup import py2exe import sys import os import shutil import glob homedir= r"E:\test\Matplotlib\multicolor" python = r"c:\Python25" # Name of python directory if File_Exists(python)==False: python = r"c:\Python23" # Name of python directory # *** # Some suggests that old build/dist should be cleared # *** dist_paths = [ homedir+'\\build', homedir+'\\dist' ] for path in dist_paths : if File_Exists ( path ) : shutil.rmtree ( path ) # *** # *** # *** data_files = [] packages = [] includes = [] excludes = [] dll_excludes = [] data_files.append ( ( '', glob.glob ( 'templates_*.*' ) ) ) # *** # For MatPlotLib # *** if MatPlotLib_Wanted : import matplotlib includes.append ( 'matplotlib.numerix.random_array' ) packages.append ( 'matplotlib' ) packages.append ( 'pytz' ) def mpl_data_files(destpath, path): mpl_data=[] for x in glob.glob (path+'\\*.*' ): if os.path.isdir(x): mpl_data_files(destpath+'\\'+os.path.split(x)[1], x) elif os.path.isfile(x): mpl_data.append(x) data_files.append ( ( destpath, mpl_data)) mpl_data_files(r'matplotlibdata', python+r'\Lib\site-packages\matplotlib\mpl-data') data_files.append ( ( r'matplotlibdata', glob.glob ( python+r'\Lib\site-packages\matplotlib\mpl-data\matplotlibrc' ))) data_files.append ( ( r'matplotlibdata\images', glob.glob ( python+r'\Lib\site-packages\matplotlib\mpl-data\images\*.*' ))) data_files.append ( ( r'matplotlibdata\fonts\afm', glob.glob ( python+r'\Lib\site-packages\matplotlib\mpl-data\fonts\afm\*.*' ))) data_files.append ( ( r'matplotlibdata\fonts\pdfcorefonts', glob.glob ( python+r'\Lib\site-packages\matplotlib\mpl-data\fonts\pdfcorefonts\*.*'))) data_files.append ( ( r'matplotlibdata\fonts\ttf', glob.glob ( python+r'\Lib\site-packages\matplotlib\mpl-data\fonts\ttf\*.*' ))) excludes.append ( '_gtkagg') excludes.append ( '_tkagg' ) excludes.append ( '_agg2' ) excludes.append ( '_cairo' ) excludes.append ( '_cocoaagg' ) excludes.append ( '_fltkagg' ) excludes.append ( '_gtk' ) excludes.append ( '_gtkcairo') excludes.append ( 'backend_qt' ) excludes.append ( 'backend_qt4') excludes.append ( 'backend_qt4agg' ) excludes.append ( 'backend_qtagg' ) excludes.append ( 'backend_cairo' ) excludes.append ( 'backend_cocoaagg' ) excludes.append ( 'Tkconstants' ) excludes.append ( 'Tkinter' ) excludes.append ( 'tcl' ) excludes.append ( "_imagingtk" ) excludes.append ( "PIL._imagingtk" ) excludes.append ( "ImageTk" ) excludes.append ( "PIL.ImageTk" ) excludes.append ( "FixTk" ) dll_excludes.append ( 'libgdk-win32-2.0-0.dll' ) dll_excludes.append ( 'libgdk_pixbuf-2.0-0.dll' ) dll_excludes.append ( 'libgobject-2.0-0.dll') dll_excludes.append ( 'tcl84.dll' ) dll_excludes.append ( 'tk84.dll' ) dll_excludes.append ( 'tclpip84.dll' ) # *
[Matplotlib-users] AXES properties
Hello, I am creating a plot with multiple y-axis (up to 6) and twinx works pretty well. The problem is that there are too much wasted spaces used up by the axes. Since I have multiple axes, it cuts into the amount of space available for the plot area. I need to know how I can squeeze some spaces out of the standard axes. First thing I discovered was that I can rotate the tick labels to vertical by: plt.setp(ax.major_ticklabels, rotation="vertical") where ax is my y-axis. But then: (1) How to reduce the space between the tick and the axes label? First I tried to place the label on top but couldn't get that to work. Then I tried to change the position property of the axis label object and that have no effect. So, can somebody please tell me how I can do these 2 things? (2) How to avoid overlapping tick labels? With the way the standard x and y axis are drawn, after I do a vertical rotate of the y tick labels, the first y tick label overlaps with the last x tick label since they are both center aligned. Is there any way to change the alignment of only the first and last tick labels of an axes (while keeping the rest center aligned)?

[Matplotlib-users] Multiple y-axis
Hi all, I am new to matplotlib. I like to know how to create a plot that contains several y-axis (up to say, 6) with only 1 x-axis (similar to the two_scales.py type plot but with all of the y-axis on one side). I know you can create multiple single curve plots on the same page but that's not what I want: I want one plot with multiple curves and one y-axis for each of the curves.

[Matplotlib-users] Controlling number of grid lines
I am having trouble with axes and grids in the y-direction. I have a 3 rows x 2 colums figure and I like to have 5 major Y divisions or 4 grid lines for each of the graphs. 5 of the 6 graphs came out properly. For instance, for a Ymin=12, Ymax=17, I get grid lines at y=13, 14, 15, and 16. However, the 6th one isn't right. For a Ymin=-5 and Ymax=5, I get grid lines at y=-4, -2, 0, 2, 4 (but the origin does starts with y=-5). I want to have only 4 grid lines (at y=-3, -1, +1, 3). I tried many settings but the result is the same. What should I do to get only 4 grid lines in the y-direction? Regards, -- John Henry - Take Surveys. Earn Cash.

However, if I view the plot at the screen first (using the show() command), maximized the plot, and then save the file, I get a very nice looking .png file.

[Matplotlib-users] Controlling vertical space between subplots
Hi list,
I have a figure of 3 rows by 2 col of plots. I have a need to use 2 line
xlabels for each of the subplots. So I did something like:
xlabel("Label 1\nLine 2")
for each of the subplots.
However when I do that, the 2nd line is lost for the top 4 subplots because I
don't have enough vertical spaces between them. I tried something like:
subplots_adjust(hspace=0.4)
but it didn't seem to have any effect (I also tried different values for hspace
- no effect at all).
What am I doing wrong?
I also have too much white space on the left and right side of the page and I
tried to reduce that using the subplots_adjust function but it didn't seem to
be doing what I want. I am sure I am not understanding something about
subplots_adjust.
Could some one please clarify it (or point me to the right direction)?
Thanks,

[Matplotlib-users] invalidrestore
Hi list, I am getting an "invalidrestore" from the printer when I print a figure created with MPL. The page prints fine but for each plot, I am getting an error page. I didn't have this problem until I started making a number of font related changes. Before I go through a bunch of painful regression steps to see what causes this, does anybody has experience in this? Don't know if it matters but I am using Word to print the .eps file by imported it into a word doc file and then print from there. I am using Word because I don't have any other software that would allow me to print .eps file. Regards, -- John Henry - Take Surveys. Earn Cash.

Re: [Matplotlib-users] invalidrestore
I installed gsview and gscript and tried it. The good news is that when I print from inside gsview, the error page is gone. The bad news is that the oritentation is wrong. My plot is designed for landscape. From word, I set the page setup to landscape, import the picture, and print. But with gsview, it imports my plot 90 degree wrong.

Re: [Matplotlib-users] invalidrestore
Thanks for pointing that out, Eric.
I try that and it did turn my plot 90 degree. The bad news is that GSview
imports it upside down and if I want to view the plot on the screen, I have to
rotate it downside up first. (Hey, I shouldn't complain. At least I can
print without wasting a piece of paper for each plot).
So, looks like it's true that something MPL did to the eps file is causing Word
to spit out that error page. I wish I know what it is.
The problem of not finding out is that I need to send these plots to clients.
I don't want to require that they have an .eps viewer in order to see my
plots...

Re: [Matplotlib-users] invalidrestore
After doing some investigation, I discovered that this problem is reproducible
using sample programs such as axes_demo.py. Here are the steps I took:
a) Run axes_demo.py
b) Save the plot as eps file
c) Start Word
d) Insert the eps file
e) Print
I got a 2 page print: 1 for the plot, and 1 for the error message
invalidrestore.
Could somebody please try and see if it fails the same on their system?

Re: [Matplotlib-users] invalidrestore
Thanks for the answer, John. Up to this point, the other software package we use produces EPS files only and so I've been using it this way for a while. May not be the best way but I've tried other EPS viewers and so far Word actually is the best way since I have to embedd the plots into Word reports. Back to the subject at hand. Using PNG files works but brings with it other problems and so I would really appreciate a resolution to this "invalidrestore" issue. I can't use PDF because I have to embedd the plots in a Word document. Not sure what SVG is (I'll look it up).

Re: [Matplotlib-users] invalidrestore - PDF
Switching to PDF works (eventually - see below) but bring with it yet another set of problems. First of all, I had to fix backend_pdf.py for MPL to work (w Python 2.3, anyway). Two problems: a) 2.3 doesn't have the sorted function - it uses a .sort() function. So, I had to change line 487 from: chars=sorted(charmap.keys()) to: chars = charmap.keys() chars.sort() b) No update() function (line 396) So, instead of: xobjects.update([(name, value[0]) for (name, value) in self.markers.items()]) Had to do: for (name, value) in self.markers.items(): xobjects[name]=value[0] After that, I got my pdf file. However, if I print the PDF directly, works fine but when I create an object link to the PDF and print from inside Word, the printout is degraded (kind of fuzzy with texts). So, for a temporary work around, I can use PDF instead of EPS and hopefully that problem will get fixed someday. > -Original Message- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On > Behalf Of Jouni K.

[Matplotlib-users] Axes label
I found an example on the web that illustrates the question I posted earlier about axes. See: http://www.scipy.org/Cookbook/Matplotlib/MulticoloredLine Notice that the y-axis goes from (-1.1, 1.1) but the first label is at -1.0. I really don't like that because when I read values off the graph, I have to keep reminding myself that the origin is at -1.1. This may seem trivial but if you have to think, walk, chew gums at the same time you're reading the graph, it gets annoying - particularly if you have to read lots of these graphs. Is there a way to force the label to start at -1.1 instead of -1.0? Thanks, -- John Henry - Take Surveys. Earn Cash.

Re: [Matplotlib-users] Axes label
Somebody at the usenet suggested that I play with the ticker formatter and locator. While that helped the multi-color sample I cited, it didn't help in my plots. The formatter only controls how the y-axis labels are formatted, whereas AFAIK the locator only affects the values of the ymajor and yminor. So, back to my original question: How do I force the first label to appear at the origin for all plots?

Re: [Matplotlib-users] Axes label
Thanks to the reply, John (Hunter). That's it. The method proposed by Jouni appears to work too: gca().yaxis.set_major_locator(LinearLocator()) but it created too many labels. The set_ytinks call is the key. The set_ylim doesn't seem to be necessary. Now I have to study and see how I can implement it as a custom locators.

Re: [Matplotlib-users] How to draw a straight line?
Thanks for the answer, John and Jouni. Okay, Line2D works. However, it appears to work in point (or is it pixels?) only. It doesn't accept xycoords="figure fraction" as an option. How can I specify xy as a fraction of the figure size? I read the transform cookbook cited by Jouni.

[Matplotlib-users] plots into multi-page pdf
Hi list, I am using matplotlib to create single page plots and the whole process works fine. However, when I am done, I end up with lots of single page pdf files. Is there a way to get matplotlib to combine them all into a single PDF file? I tried using another package PyPDF but ended up with either file I/O problems or too many file opened problem. I am hoping that this can be done within matplotlib and not require yet another package. Thanks, -- John Henry - Take Surveys. Earn Cash.

Hi list, First of all, thanks to Bill Dandreta and Jouni Seppanen for helping with my combining single page pdf into multipage pdf question.

Starting with the 9th page, MPL chokes at line 1084 in backend_pdf.py and couldn't find the cooresponding ttf file (VeraSe.ttf) but it had no problem reading that file for the first 8 plots. ???

[Matplotlib-users] What kind of chart should I use?
Hi list, I have a set of time series data which is year's worth of wind speed at a particular place (one data point per minute). I want to see how wind speed spreads throughout the day. I can do a scatter char with 24 hours of the day vs wind speed but then I end up with something that's not too useful (too many data points). What's more interesting is to present the data as a time / wind speed / frequency plot. The kind of plot shown in image_interp.py looks interesting. Is there a way to combine the capability of plot_date and imshow? If so, may be I can have hour of the day vs wind-speed with the color be a function of the data frequency.

Re: [Matplotlib-users] plotting wind-speed time series
Derek, When you say "on version 5", do you mean windrose itself is on version 5? May be that's why in your sample code, you invoked windrose via: freq,ax=windrose.windplot(ventV,ventD,counts=False,speed_classes=[0.1,0.2,0.3,0.4,0.5],sectors=8,style='bar2') but the version of windrose from John Hunter's message (http://www.nabble.com/windrose-t1392107.html) doesn't look anywhere like that. I have not received a response from the author. Could you please post version 5 of windrose.py? Appreciate it. I would suggest contacting the author directly. windrose.py is on version 5 (AFAIK).

Now, I am trying to convert my data into a format acceptable to windrose.

[Matplotlib-users] SVG vs PNG
Hi, list: In my quest to create MPL plots for insertion into Word documents, I tried post-script (doesn't work well - Word doesn't like the ps file created by MPL), pdf (can't create more then 8 plots per job and can not import into word), png (works but each plot needs to be magified manually before saving), and now I am playing around with the svg format. Word doesn't recognize the svg format but I can open the file in gimp, select the portion of the chart I need, and do cut-and-paste over to Word. I can do the same with png format too but svg format works better if I have to do cut and paste and scale. My question is this: While the svg files are much smaller then the cooresponding png file (yes, and scalable), I am surprised that the quality of the plot doesn't seem to be that much better (seem like about the same as compared to a corresponding png figure). I would have thought that they should (see for example: http://luxor-xul.sourceforge.net/talk/jug-nov-2002/slides.html#svg-1). Is this because MPL is not taking advantage of the capabilities offered by svg? I know that not every one works with Word but for good or for bad, that's what I have to work with in oder to submit my paper for publishing. Surely many of you have come across this kind of chanllenge. What have you been doing for inserting MPL created charts into Word?

Thanks everybody for the explanation of svg in Gimp. That makes sense. Is there any vector based program that does what Gimp does? > Did you try eps rather than ps? > > Eric Yes, I tried eps. Word won't recognize that neither. As to the EMF format, I downloaded the package and attempted to apply the patch. Failed - probably because it's intended for 0.85 only. I am running 0.90 of MPL.

Re: [Matplotlib-users] SVG vs PNG
Chris, All I want is to: a) Insert all of the plots I create with MPL onto a Word document. As I said before, my version of Word does not recognize the EPS or PS format created by MPL. I am not blaiming MPL. I am just not willing to send Redmond money to see if their later version does the job properly. The version of Word I have does not import PDF files neither. Besides, the PDF backend of MPL fails when the total number of figures is more then 8. b) Be able to cut and paste part of a MPL figure and insert that to Word. I can do it now via the Gimp path but as I explained previously, the quality is not the greatest. I'll look up the cookbook you cited and try that.

Re: [Matplotlib-users] SVG vs PNG
Bingo! My prayer appears to have been answered. inkscape has no trouble reading the .svg files created by MPL, and Word has no trouble reading the .eps files created by inkscape. So, at least I can use it to preserve the vectors. Too bad inkscape doesn't read .eps directly (complaining...complaining) :=) inkscape treats everything as objects and allows you to ungroup the plots into elements and then you can play with each of the elements individually. When I am done, I can then insert into Word. Too bad it doesn't allow me to paste the objects directly over to Windows but I am not complaining.

Re: [Matplotlib-users] SVG vs PNG
Yes, that's what I've been forced to do. The problem with that is that it forces you to fix the size of the figures in your paper. When I reformat things around in subsequent revisions, I have to go back and recreate the figures - if the spacing changes. I would much rather retaining the ability to rescale in Word. Yes, I know that it does change the font size. But as I indicated in my other message, I think Inkscape is the solution. I am still playing around with it and see if that really does it but it looks real promising. Regards, -Original Message- From: David Huard [mailto:[EMAIL PROTECTED] Sent: Friday, May 11, 2007 12:06 PM To: [EMAIL PROTECTED] Subject: Re: [Matplotlib-users] SVG vs PNG My advice would be to define the size you'll want the figure to be on paper once printed, and set the resolution to 300 dpi (for paper) or 100 (for screen): e.g. fig.savefig(figsize=(8,8), dpi=300) Rescaling the figure is generally a bad idea for inclusion in a paper since it changes the font size as well. To get a nice output, you try to keep the same font size for both paper and figures, and the simplest was to do this is by avoiding rescaling.

Actually, Gimp is the problem. It's obvious they don't have a very good rendering engine.

[Matplotlib-users] This is just so perfect! (was: Re: SVG vs PNG)
This is simply too good to be true. I played with manupulating MPL plots using Inkscape and man, somebody ought to include this in the MPL FAQ. I can move everything around by elements, touch-up or remove things I don't want, scale it, rotate it, you name it. And then I can save the file in .eps and include into Office - and I don't loose any quality. Perfect! Here's what I learned: a) Create the plot under MPL, saving the file in .svg format, and use the figsize argument to figure to create a plot of the proper size b) Use Inkscape to open the .svg file and manupulate it. Save in .eps format. c) Import the .eps file into Office. d) Be happy and become famous and rich. (not) Thanks again for all of the suggestions and tips.

[Matplotlib-users] This is just so perfect! (was: Re: SVG vs PNG)
Sorry. Just discover that saving the file in emf format under Inkscape and then import into Word works even better. The eps engine in Word is really bad.

Re: [Matplotlib-users] SVG vs PNG
Not exactly OT.
I would not recommend using .eps format in order to
export MPL graphs for Inkscape. I've been playing
around with Inkscape for a few days now and I've been
using .svg exclusively and don't have any problem.
As I said before, I like the fact that once I am
inside Inscape, I can do an ungroup of the graph, and
work with all of the plotting elements individually.
In fact, I just discover a nice way to "cut and paste"
a particular subplot over to PowerPoint. This gives
me very high quality graphs in Power Point (I can
scale all I want). No more fuzzy, ugly-looking Power
Point charts.
Here's how:
a) Create MPL plots in .svg format
b) From Inscape, read in .svg
c) Select subplot and ungroup
d) Copy and paste to a new page
e) Shrink the page down to the size of the object
f) Save as emf file
g) Import into PowerPoint
In addition, I am also using Inscape to get around the
problem with the PDF backend in MPL. I reported
previously that I am unable to save more then 8 PDF
files per execuation. Now, I save the files in .svg
format, then invoke Inscape in command line mode and
export the file in pdf format. Works great.

Re: [Matplotlib-users] SVG vs PNG
This SVG format gets better everyday. For those of you unfortunate enough not to have the choice of freedom from the M$ Monopoly, I discovered that Visio supports SVG file directly. In fact, the rendering is better then Inscape and get this: you can copy and paste *directly* over to PowerPoint and Word and you can even embed it as a Visio object. The quality is superb! Even the browser can read SVG file (somewhat - the quality isn't very good). > -Original Message- > From: Derek Hohls > Sent: Tuesday, May 15, 2007 12:19 AM > Subject: Re: [Matplotlib-users] SVG vs PNG > > > For those of you fortunate enough to have the > choice be free from the M$ Monopoly, you can > use the Open Office Impress package to do > something similar to the steps below. > > However, if you want to work directly with SVG > files, then you should install the SVG "import > filter", available from: http://www.ipd.uka.de/~hauma/svg-import/ > (Installation and use are described very clearly). > > If you have saved an SVG file from MPL, you > can now open it in Open Office Draw, ungroup > it (you will need to repeat this command a > number of times) and edit the elements. > Save the file as an Open Office drawing > (.odg) for use in other Open Office applications. > > One strange thing I encountered was that the > default background for fonts was blue? > This seems to be a problem with the > import filter, and has been reported on the > wiki support page: > http://wiki.services.openoffice.org/wiki/SVG_User_Experiences# > Blue_background_for_all_text_elements > > but not fixed.
