property Bitmap: TBitmap;
Description
Bitmap points to a TBitmap object that holds a BMP image. If Bitmap is nonempty, the BMP image (rather than the Style property) defines the brush抯 pattern. If the image is larger than eight pixels by eight pixels, only the top left eight-by-eight region is used.
Changing the image does not affect the brush until the TBitmap is reassigned to the Bitmap property. Be sure to free the TBitmap after finishing with the brush, since TBrush will not free it.请注意一下 eight pixels by eight pixels的要求。谢谢
UINT fuColorSpec // color table data
);
ParametershglbDIBPackedIdentifies a global memory object containing a packed DIB, which consists of a BITMAPINFO structure immediately followed by an array of bytes defining the pixels of the bitmap. Windows 95: Creating brushes from bitmaps or DIBs larger than 8x8 pixels is not supported. If a larger bitmap is specified, only a portion of the bitmap is used.
