L_MosaicBitmap

#include "l_bitmap.h"

L_INT EXT_FUNCTION L_MosaicBitmap(pBitmap, uDim)

pBITMAPHANDLE pBitmap;	/* pointer to the bitmap handle */
L_UINT uDim;	/* dimensions of the tiles (uDim x uDim), in pixels */

Imposes a mosaic effect on a bitmap by dividing the bitmap into tiles of a specified size and changing the color of all pixels in each tile to the average color of pixels within the tile.

Parameter	Description
pBitmap	Pointer to the bitmap handle that references the bitmap to be affected.
uDim	Dimensions of the tiles (uDim x uDim), in pixels.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Example

For complete sample code, refer to the CHILD.C module of the DEMO example.

/* This example loads a bitmap and applies a mosaic effect. */
BITMAPHANDLE LeadBitmap; /* Bitmap handle to hold the loaded image. */
/* Load the bitmap, keeping the bits per pixel of the file */
L_LoadBitmap (TEXT("IMAGE1.CMP"), &LeadBitmap, sizeof(BITMAPHANDLE), 0, ORDER_BGR, NULL, NULL);
/* Apply a mosaic effect with 3x3 tiles */
L_MosaicBitmap(&LeadBitmap, 3 );
