今天在研究bmp文件，发现建立单色bmp(2色)图片时，用utraedit打开发现没用的空位，不知作何解释，高手请教！
现象，如建立大小为16*14的单色图片，数据为：
00h:42 4d 76 00 00 00 00 00 00 00 3E 00 00 00 28 00
01h:00 00 10 00 00 00 0e 00 00 00 01 00 01 00 00 00
02h:00 00 38 00 00 00 00 00 00 00 00 00 00 00 00 00
03h:00 00 00 00 00 00 00 00 00 00 ff ff ff 00 ff ff
04h:00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff
05h:00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff
06h:00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff
07h:00 00 ff ff 00 00
如按1位2进制对应1个像素的话，ff 后的0应该有效，但实际 0(蓝色部分以及后的0)改成任何数对图片都 没影响？
谁给分析 下原因啊
