GIFX.EXE (CONSOLE GIF JOIN TOOL, COPYRIGHT@2017~2019 BY HAPPY, VERSION 1.0)
摘要：
=========================================================================
GIFX.EXE，是一款奇异的命令行gif拼接、解包利器。 能将gif动态图的每一帧拼接
为一整张静态图，亦能将gif文件解包。同时也支持其他图片格式的转换、裁剪、透
明色处理等操作。
=========================================================================

版本：
VERSION 1.0

用法：
-------------------------------------------------------------------------
gifx   [输入文件]
    -o [输出文件]
    -c [[裁剪区域X坐标],[裁剪区域Y坐标],[裁剪区域宽度],[裁剪区域高度]]
    -s [[显示宽度],[显示高度]]
    -i [帧间隔]
    -j [跳过的帧]
    -t [[R],[G],[B]]
    -m [l|v|x]
-------------------------------------------------------------------------

示例：
-------------------------------------------------------------------------
REM 解包test.gif并设白色为透明色，输出为png格式
gifx test.gif -o.png -t255,255,255 -mx

REM 解包test.gif并拼接每一帧为一整张纵向图，输出为jpg格式
gifx test.gif -o.\out.jpg -t255,255,255 -mv

REM 解包test.gif每帧为宽100、高300的位图并拼接每一帧为一整张横向图，输出为bmp格式
gifx test.gif -o.\out.jpg -s100,300 -ml   

REM 图片格式转换
gifx test.png -o.\test.jpg

REM 图片裁剪
gifx test.png -c20,30,100,300 -s100,600 -o.\out.png

REM 设置某色为透明色，颜色为RGB格式，中间用英文逗号隔开
gifx test.png -t255,255,255 -o.\out.png
