Thanks. I've just been looking at the x11 protocol and xpixmaps width/height is stored as 16-bit unsigned int (CARD16.) Anyways, it just makes sense to run out of memory for really huge pixmpas. -- Emmanuel Thomas-Maurin manutm...@gmail.com ___ XFree86 mailing list XFree86@XFree86.Org http://XFree86.Org/mailman/listinfo/xfree86
[XFree86] Is there a defined xpixmap width limit?
Good day list! I've been searching for this for a while but, so far, it's still unclear to me : Is there a width and height limit for pixmaps? Widht / height type is int but I'm wondering what's the maximum supported values. I'm using GTK and I know GDK pixmaps and windows can't be wider than 65535. But I got a crash in a GTK app when trying to create a big pixmap, less wide than 65535 but wider than 32767: The program 'my_app' received an X Window System error. This probably reflects a bug in the program. The error was 'BadAlloc (insufficient resources for operation)'. So my question is: Is it an 'out of memory' error (returned by malloc) or a width value above a defined limit? Mainly, I'd like to know if this is documented somewhere. I can provide an example programme that reproduces the issue. Thanks in advance for any hints. -- Emmanuel Thomas-Maurin manutm...@gmail.com ___ XFree86 mailing list XFree86@XFree86.Org http://XFree86.Org/mailman/listinfo/xfree86
