; GIF LITE v3.0 by Willow
|
||||
; Written in pure assembler by Ivushkin Andrey aka Willow
|
||||
; Modified by Diamond
|
||||
;
|
||||
; This include file will contain functions to handle GIF image format
|
||||
;
|
||||
; Created: August 15, 2004
|
||||
; Last changed: June 24, 2007
|
||||
|
||||
; Requires kglobals.inc (iglobal/uglobal macro)
|
||||
; (program must 'include "kglobals.inc"' and say 'IncludeUGlobal'
|
||||
; somewhere in uninitialized data area).
|
||||
|
||||
; Configuration: [changed from program which includes this file]
|
||||
; 1. The constant COLOR_ORDER: must be one of
|
||||
; PALETTE - for 8-bit image with palette (sysfunction 65)
|
||||
; MENUETOS - for MenuetOS and KolibriOS color order (sysfunction 7)
|
||||
; OTHER - for standard color order
|
||||
; 2. Define constant GIF_SUPPORT_INTERLACED if you want to support interlaced
|
||||
; GIFs.
|
||||
; 3. Single image mode vs multiple image mode:
|
||||
; if the program defines the variable 'gif_img_count' of type dword
|
||||
; somewhere, ReadGIF will enter multiple image mode: gif_img_count
|
||||
; will be initialized with image count, output format is GIF_list,
|
||||
; the function GetGIFinfo retrieves Nth image info. Otherwise, ReadGIF
|
||||
; uses single image mode: exit after end of first image, output is
|
||||
; <dd width,height, times width*height[*3] db image>
|
||||
|
||||
if ~ (COLOR_ORDER in <PALETTE,MENUETOS,OTHER>)
