L_ColoredPencilBitmap
#include "l_bitmap.h"
L_INT EXT_FUNCTION L_ColoredPencilBitmap(pBitmap, uRatio, uDim);
|
pBITMAPHANDLE pBitmap; |
/* pointer to the bitmap handle */ |
|
L_UINT uRatio; |
/* color adjustment percentage */ |
|
L_UINT uDim; |
/* size of the pencil coloring neighborhood */ |
Applies an effect to a bitmap that makes it look like it has been drawn with colored pencils. This function is available in the Raster Pro and above toolkits.
|
Parameter |
Description |
|
pBitmap |
Pointer to the bitmap handle that references the bitmap on which to apply the effect. |
|
uRatio |
Value that represents how much the bitmap colors should be adjusted so they appear to be colored pencil colors. Valid values range from 0 to 100. A value of 0 means that the bitmap will not have any change in pixel values, whereas a value of 100 means that the maximum possible amount will be added to the pixel values. |
|
uDim |
Value that represents the size of the pencil coloring neighborhood. It is the length, in pixels, of one side of a square. Valid values range from 0 to 100. Increasing this value increases the thickness of the edges that are detected. |
Returns
|
SUCCESS |
The function was successful. |
|
< 1 |
An error occurred. Refer to Return Codes. |

Example
/* The following example loads a bitmap and applies the colored pencil 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);
/* pencil color the bitmap with Ratio value of 50 and with a neighborhood of 3x3 pixels*/
L_ColoredPencilBitmap(&LeadBitmap, 50, 3);
