XPM格式说明:

xpm_data = [
"10 12 4 1",
"  c Green",
". c Red",
"X c Blue",
"Y c #00000FFFFFF",
"XXXXXXXXXX",
" XXXXXXXX ",
"  XXXXXX  ",
"   YYYY   ",
"    YY    ",
"    YY    ",
"    YY    ",
"    YY    ",
"..........",
"..........",
"..........",
".........."
]

 

"10 12 4 1",其中10表示象素宽度，12表示象素高度，4表示色彩种类，最后一个数字说明的是每个字母当作各个颜色的标记

下面4行就是每个字符代表的色彩

再下面的10列12行的字符表示图像的每个像素
