.SH NAME
is_linear_bitmap \- Tells if a bitmap is linear. Allegro game programming library.\&
.SH SYNOPSIS
.B #include <allegro.h>

.sp
.B int is_linear_bitmap(BITMAP *bmp);
.SH 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().
