L_SolarizeBitmap

#include "l_bitmap.h"

L_INT EXT_FUNCTION L_SolarizeBitmap(pBitmap, uThreshold)

pBITMAPHANDLE pBitmap;	/* pointer to the bitmap handle */
L_UINT uThreshold;	/* intensity threshold */

Applies an effect that mimics the accidental exposure of photographic film to light. It does so by inverting all color data with an intensity value greater than or equal to the threshold that you specify.

Parameter	Description
pBitmap	Pointer to the bitmap handle that references the bitmap to be affected.
uThreshold	Threshold at or above which colors are to be inverted. The valid range is from 0 - 65535 for 64-bit, 48-bit and 16-bit grayscale images and from 0 - 4095 for 12-bit grayscale images. Otherwise, it is from 0 to 255.

Returns

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

Comments

This function supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.

Example

/* This example loads a bitmap and solarizes it. */
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);
/* Solarize with threshold of 90 */
L_SolarizeBitmap(&LeadBitmap, 90 );
