Fri Feb 2 17:16:09 2001 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkcolor-x11.c (gdk_colormap_sync): Make gdk_colormap_sync private since it was never exported in a header file. * gdk/x11/gdkcolor-x11.c (gdk_colormap_new): Fill in colormap->colors[] for StaticGray, StaticColor colormaps. * gdk/gdkpixbuf-drawable.c: Fix problems where image->bpp was being used as if it was image->bits_per_pixel. * gdk/gdkimage.h, gdk/x11/gdkimage-x11.c: Save the bits-per-pixel for the image in the GdkImage structure since it isn't reconstructable, and we need it to handle packed types * gdk/win32/gdkimage-win32.c: Set image->bits_per_pixel. (I'm making the assumption that on Win32 image->bits_per_pixel == image->depth, always. * gdk/linux-fb/gdkimage-fb.c: Set image->bits_per_pixel. * gdk/gdkrgb.c (gdk_rgb_select_conv): Exit with an informative warning message if no converter can be found.

/* Types of images.
|
|
* Normal: Normal X image type. These are slow as they involve passing
|
|
* the entire image through the X connection each time a draw
|
|
* request is required. On Win32, a bitmap.
|
|
* Shared: Shared memory X image type. These are fast as the X server
|
|
* and the program actually use the same piece of memory. They
|
|
* should be used with care though as there is the possibility
|
|
* for both the X server and the program to be reading/writing
|
|
* the image simultaneously and producing undesired results.
|
|
* On Win32, also a bitmap.
