L_EmbossBitmap

#include "l_bitmap.h"

L_LTIMGEFX_API L_INT L_EmbossBitmap(pBitmap, uDirection, uDepth, uFlags)

pBITMAPHANDLE pBitmap;	pointer to the bitmap handle
L_UINT uDirection;	direction of the apparent light source
L_UINT uDepth;	apparent depth of this three-dimensional effect
L_UINT32 uFlags;	flags

Applies an emboss effect to a bitmap, letting you specify the depth and direction of the effect.

Parameter	Description
pBitmap	Pointer to the bitmap handle referencing the target bitmap.
uDirection	The direction of the apparent light source. Valid values are:
	EMBOSS_N	[0]
	EMBOSS_NE	[1]
	EMBOSS_E	[2]
	EMBOSS_SE	[3]
	EMBOSS_S	[4]
	EMBOSS_SW	[5]
	EMBOSS_W	[6]
	EMBOSS_NW	[7]
uDepth	The apparent depth of this three-dimensional effect. Valid values are 0 to 1000, with 500 as normal.
uFlags	Reserved for future use. Must be 0.

Returns

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

Comments

To update a status bar or detect a user interrupt during execution of this function, refer to L_SetStatusCallback.

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 in the Document and Medical Imaging toolkits.

This function does not support 32-bit grayscale images. It returns the error code ERROR_GRAY32_UNSUPPORTED if a 32-bit grayscale image is passed to this function.

Example

For complete sample code, refer to the CHILD.C module of the DEMO example. This example loads a bitmap and embosses it.

#define MAKE_IMAGE_PATH(pFileName) TEXT("C:\\Users\\Public\\Documents\\LEADTOOLS Images\\")pFileName 
L_INT EmbossBitmapExample(L_VOID) 
{ 
   L_INT nRet; 
   BITMAPHANDLE LeadBitmap;   /* Bitmap handle to hold the loaded image. */ 
   /* Load the bitmap, keeping the bits per pixel of the file */ 
   nRet = L_LoadBitmap (MAKE_IMAGE_PATH(TEXT("ImageProcessingDemo\\NaturalFruits.jpg")), &LeadBitmap, sizeof(BITMAPHANDLE), 0, ORDER_BGR, NULL, NULL); 
   if(nRet !=SUCCESS) 
      return nRet; 
   /* Emboss with northeast direction and average depth */ 
   nRet = L_EmbossBitmap(&LeadBitmap, EMBOSS_NE, 500 , 0); 
   if(nRet !=SUCCESS) 
      return nRet; 
   nRet = L_SaveBitmap(MAKE_IMAGE_PATH(TEXT("Result.BMP")), &LeadBitmap, FILE_BMP, 24, 0, NULL); 
   if(nRet !=SUCCESS) 
      return nRet; 
   //free bitmap 
   if(LeadBitmap.Flags.Allocated) 
      L_FreeBitmap(&LeadBitmap); 
   return SUCCESS; 
}
