宽度和高度的值是多少?
答案 0 :(得分:2)
Offset (hex) Offset (dec) Size (bytes) Windows BITMAPINFOHEADER[1]
0E 14 4 the size of this header (40 bytes)
12 18 4 the bitmap width in pixels (signed integer)
16 22 4 the bitmap height in pixels (signed integer)
使用您发布的位图标题,宽度和高度将为
Width: D1 02 00 00
Height: 1D 02 00 00
上面的维基百科链接指出
所有整数值都以little-endian格式存储(即 最不重要的字节优先。)
如果我的理解是正确的,那就转换为
Width = 209 + (2 x 256) + (0 x 256^2) + (0 x 256^3) = 721
Height = 29 + (2 x 256) + (0 x 256^2) + (0 x 256^3) = 541
