SYNOPSIS

10       #include <allegro.h>
11
12
13       int is_linear_bitmap(BITMAP *bmp);
14

DESCRIPTION

16       Returns TRUE if bmp is a linear bitmap,  i.e.  a  bitmap  that  can  be
17       accessed  linearly  within  each scanline (for example a memory bitmap,
18       the DOS VGA or SVGA screen, Windows bitmaps, etc). Linear  bitmaps  can
19       be  used  with  the  _putpixel(),  _getpixel(),  bmp_write_line(),  and
20       bmp_read_line() functions.
21
22       Historically there were only linear and planar bitmaps for Allegro,  so
23       is_linear_bitmap() is actually an alias for !is_planar_bitmap().
