XPM格式說明:

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表示象素寬度，12表示象素高度，4表示色彩種類，最后一個數(shù)字說明的是每個字母當作各個顏色的標記

下面4行就是每個字符代表的色彩

再下面的10列12行的字符表示圖像的每個像素
