$tagBITMAPINFO

这个结构定义基于Windows的设备无关位图(DIB)的尺寸和颜色信息.

Global Const $tagBITMAPINFO = "dword Size;long Width;long Height;word Planes;word BitCount;dword Compression;dword SizeImage;" & _
        "long XPelsPerMeter;long YPelsPerMeter;dword ClrUsed;dword ClrImportant;dword RGBQuad"

 

参数

Size The number of bytes required by the structure, minus the size of the RGBQuad data
Width 指定位图宽度, 单位为像素
Height 指定位图高度, 单位为像素
Planes Specifies the number of planes for the target device. This must be set to 1
BitCount Specifies the number of bits-per-pixel
Compression Specifies the type of compression for a compressed bottom-up bitmap
SizeImage Specifies the size, in bytes, of the image
XPelsPerMeter Specifies the horizontal resolution, in pixels-per-meter, of the target device for the bitmap
YPelsPerMeter Specifies the vertical resolution, in pixels-per-meter, of the target device for the bitmap
ClrUsed Specifies the number of color indexes in the color table that are actually used by the bitmap
ClrImportant Specifies the number of color indexes that are required for displaying the bitmap
RGBQuad An array of tagRGBQUAD structures. The elements of the array that make up the color table.
