[comp.windows.x] Need help displaying bit-mapped images

thomas@cme-durer.ARPA (Bruce Thomas) (03/26/88)

I need to know the format for a file holding a bit-map image for display
under X windows V10.  This file format will have to handle images of different
sizes.  What are the functions for displaying this image?

The bitmap storage format is documented in the bitmap(1) manual page.

You want to start with a look at XReadBitmapFile(), as defined in
Xlib/XReadBitmapF.c.  If you plan on using larger bitmaps (like a
full-screen background), you probably want to change the line

    while ((status = fscanf (file, "#define %80s %2d\n", variable, &value))==2)

to

    while ((status = fscanf (file, "#define %80s %d\n", variable, &value))==2)
