[pygtk] GdkImLib: Image(filename) seems to cache
Hi! I use GdkImLib.Image(filename) to load and display jpeg files. The picture gets displayed on a window where the user can choose to rotate the image: img=GdkImLib.Image(filename) #(1)... rotate filename with shell script calling image-magic img=GdkImLib.Image(filename) The second time I load it, it is not rotated although the jpeg data got rotated. Does GdkImLib cache the image? It even gets stranger: If I add img=None at (1) the image gets rotated if I rotate it 90 or 270 degrees. If it gets rotated 180 I still see the old picture. Does someone know why the images gets cached? thomas -- Thomas Guettler <[EMAIL PROTECTED]> http://www.thomas-guettler.de ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/

Well, it might not be the answer you wanted, but according to the gnome documentation, if you plan to work with gnome 2.0, you should switch to gdk-pixbuf, which actually works under windows : http://developer.gnome.org/doc/API/2.0/gdk-pixbuf/a4076.html Hope this help, -- Prof ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/

See http://groups.yahoo.com/group/gimpwin-dev/message/91 The native port of gdkimlib has been "abandoned" by the author of gtk+ on win32. I guess the only solution is to compile gtk+-1.2, gdkimlib and pygtk for X11 using cygwin and its port of XFree 4.2. The other solution is to port your application to pygtk-1.99.x !

[pygtk] GdkImlib under MS Windows ?
Hello, I am trying to port an existing Python (pygtk) application to run under Windows. The library that I am unable to find for windows is GdkImlib. Is there an existing windows port (any version at this point)? If not, are there reasons why it might not compile (dependencies?).

[pygtk] GdkImlib question
In my pygps application, I've got a map that moves as you walk around
with your GPS connected to your laptop or (in my case) Linux iPAQ.
But I'm having a really weird problem. I do this to load the map:
img = GdkImlib.Image("maps/"+world[8])
and I save it in a global variable. Then, later, I do this:
img.render()
pix, mask = img.get_pixmap()
print img, pix, mask
win = mapd.get_window()
if win:
# draw the map on the pixmap.
# if this map does not completely cover the screen, we might want to
# draw another map next to this one.
draw_pixmap(map_pixmap, mapd.get_style().white_gc, pix,
current_map_center[0] - win.width/2, current_map_center[1] -
win.height/2,
0,0, win.width,win.height)
See that print statement? When the program works, it prints this:
None
If I move the img.render() call immediately after I load the map, it
prints this:
None
Is there anything I can do about this? Obviously I can't draw a
Pixmap using a Window, so the draw_pixmap() fails. I'd really prefer
to leave the image rendered so I can scribble the user's movements on
the pixmap in the form of an arrow. Also, I'd like to be able to zoom
in or out, so I'll render the pixmap twice or half size. That's an
expensive operation, so I'd like to only do it once.

Change this to:

If the pixmap has some transparency, then you will want to set the
clipmask for the GC first. If it is just a normal square pixmap, you can
ignore the mask.

There are two problems, though i don't know what's causing them. I've filed bug reports. Everything works perfectly in C, so i don't know what's going on. The first problem is that for some reason Imlib doesn't think it knows how to load PNGs any images when accessed from Python. Because of this, it tries to use convert from ImageMagick. Unfortunately, it doesn't have the correct path to conver (it's using /convert). That is the problem with the Helix packages. The normal Debian packages only have the first problem. They successfully load images with convert, but transparency doesn't work. Imlib loads the images without convert when accessed from a C program. -- Eric Gillespie, Jr. <*> [EMAIL PROTECTED] "With sufficient thrust, pigs fly just fine.

It looks like your version of imlib was compiled without built-in xpm
support and tried to fall back on ImageMagick to convert the xpm file
into something it could handle. Since "convert" wasn't found you either
don't have ImageMagick on your system, or your PATH doesn't include the
directory convert was installed in. The best solution would be to
recompile imlib with xpm support, but you could try installing
ImageMagick (or updating your PATH if it's already installed) if you
want a quick fix.

For me, this program dies at the same place my test did (in

Is it "/home/epg/test.xpm" or "/home/epg/1.xpm" ?? Check the filename
