#include "ltwrappr.h"

virtual L_INT LBitmapBase::ConvertFromDDB(hDC, hBitmap, hPalette)

HDC hDC;	/* handle to the device responsible for the conversion*/
HBITMAP hBitmap;	/* handle to the DDB to be converted*/
HPALETTE hPalette;	/* handle to the palette */

Converts a Windows device dependent bitmap (DDB) into an LBitmapBase objects 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 objects bitmap.
