HPALETTE hPalette; |
/* handle to the palette */ |
Converts a Windows device dependent bitmap (DDB) into an LBitmapBase object’s bitmap. When this function is completed, there are two copies of the image in memory: the original DDB and the LEAD bitmap. Freeing one will not affect the other.
Parameter |
Description |
hDC |
Handle to the device responsible for the conversion. The mapping mode of the device context must be MM_TEXT. |
hBitmap |
Handle to the DDB to be converted. |
hPalette |
Handle to the palette. This value can be NULL if the hDC parameter refers to a device that is greater than 8 bits, or if the bitmap will use the system palette. |
Returns
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Comments
This function updates information in the bitmap handle and copies the DDB image data into the LBitmapBase object’s bitmap.
