is_linear_bitmap(3)             Allegro manual             is_linear_bitmap(3)

NAME
       is_linear_bitmap - Tells if a bitmap is linear. Allegro game
       programming library.

SYNOPSIS
       #include <allegro.h>

       int is_linear_bitmap(BITMAP *bmp);

DESCRIPTION
       Returns TRUE if bmp is a linear bitmap, i.e. a bitmap that can be
       accessed linearly within each scanline (for example a memory bitmap,
       the DOS VGA or SVGA screen, Windows bitmaps, etc). Linear bitmaps can
       be used with the _putpixel(), _getpixel(), bmp_write_line(), and
       bmp_read_line() functions.

       Historically there were only linear and planar bitmaps for Allegro, so
       is_linear_bitmap() is actually an alias for !is_planar_bitmap().
