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. |
