I'm trying to get an X11 Pixmap from a GDK rendering function as follows
(my_pixbuf has been created by gdk-pixbuf-csource):
GdkPixmap *gdkIcon;
GdkBitmap *gdkIconMask;
Pixmap Icon;
Pixmap IconMask;
gtk_init(&argc, &argv);

Hello, I'm new to the mailing list, but the reason I signed up was because
I've been trying to find out

For example, this code is purely pseudo code but should hopefully make it

How can I check the maximal width/height of GdkPixmap?

What is this program intende
ere a way to transform a pixbuf to a pixmap
without losing the alpha channel?
gdk_pixbuf_render_pixmap_and_mask returns a GdkPixmap and a GdkBitmap;
the mask; from a GdkPixbuf. I don't need any pixbuf at all, but that's
the only convenient way I found to load any picture forma

Image is not well written ...
lines seems to be mixed ... Alignement is incorrect ..
I suppose this is due to a wrong usage of dithering/depth parameters ...
data is pointing to a rgb buffer ...
the same call was working fine when writing directly to a windows instead of
a newly created
pixmap.

Thanks to those who replied. gdk_draw_drawable is working. I know you
have to unref certain kinds of objects. Do you have to unref a GdkPixmap
when finished with it?

I have a GdkPixmap. I need to programmatically extract a new GdkPixmap
from this image based on x- and y-coordinates, plus width and height. The
x, y, width, and height parameters will vary too much at runtime to store
all the copies needed. Conceptually this seems simple. But from among

Hi,
after following the scribble example on the Gtk tutorial I try to save
the image produced. Looking on the documentation of GdkPixbuf I found
I could use the following which however gives me a segmentation fault
in my program.

Hi,
I have written a program pretty much by re-adjusting the scribble

Isnt g_object_ref suppose to create a completely new
image or does always point to the same image. Maybe
thats why the image keeps updating itself.
Yes, g_object_ref just increases the reference counter of the object, it doesn't
create a new object.

Hello all,
I'm having a really difficult time doing something I feel ought to be
rather easy.
I'd like to draw arbitrary widgets surrounded by a colored border. I
decided the best way to do this would be to layout the widgets normally
inside of a container (e.g. a VBox) then plac
Hi,
We are working on gtk+2.0/gnome libraries.
We hv created a GdkPixmap object which is

the window.
Now, I need to convert the pixmap to a bitmap
and
store it in a file as .bmp .
Can someone help in converting it and storing it
as
a file.?
Thanks
