BITMAPV5HEADER结构是位图信息头文件。 它是BITMAPINFOHEADER结构的扩展版本。 语法 C++复制 typedefstruct{DWORD bV5Size; LONG bV5Width; LONG bV5Height; WORD bV5Planes; WORD bV5BitCount; DWORD bV5Compression; DWORD bV5SizeImage; LONG bV5XPelsPerMeter; LONG bV5YPelsPerMeter; DWORD bV5ClrUsed; ...
如果将BITMAPINFOHEADER强制转换为BITMAPINFO,则 bmiHeader成员引用BITMAPINFOHEADER,bmiColors成员引用颜色表中的第一个条目或第一个颜色掩码。 请注意,如果位图使用颜色表或颜色掩码,则整个格式结构的大小 (BITMAPINFOHEADER加上颜色信息) 不等于sizeof(BITMAPINFOHEADER)或sizeof(BITMAPINFO)。 必须计算每个实例的实...
If the bitmap is a packed bitmap (a bitmap in which the bitmap array immediately follows the BITMAPINFO header and is referenced by a single pointer), the biClrUsed member must be either zero or the actual size of the color table.b...
