L_FillBitmap

#include "l_bitmap.h"

L_LTKRN_API L_INT L_FillBitmap(pBitmap, crFill)

pBITMAPHANDLE pBitmap;	/* pointer to the bitmap handle */
L_COLORREF crFill;	/* fill color */

Fills the specified bitmap with the specified color.

Parameter	Description
pBitmap	Pointer to the bitmap handle referencing the target bitmap.
crFill	The fill color. The standard Windows values for COLORREF represent either red, green, and blue color values, or an index into the bitmap's palette. A COLORREF value with the format 0x00BBGGRR represents the blue, green, and red color values for the specified pixel, where 0xBB is the blue value, 0xGG is the green value and 0xRR is the red value. If 0x01000000 is set in the COLORREF value (0x010000ZZ), the lower 8 bits (0xZZ) represent an index into the bitmap's palette which holds the color value. These COLORREF values can be used with any Windows function and macro that takes a COLORREF parameter
	In the Document/Medical Imaging editions, the COLORREF value may represent a 16 bit grayscale value if pBitmap is a 12 or 16-bit grayscale bitmap. So that the value is not confused with an RGB value, the COLORREF_GRAY16 mask (0x04000000) is set. In this case (0x0400YYYY), the lower 16 bits (0xYYYY) of the COLORREF value represent the 16-bit grayscale value. (0x0400FFFF is 16-bit white and 0x04000000is 16-bit black.) This is not a standard Windows value. Therefore, LEADTOOLS functions will recognize a COLORREF having this format, but Windows functions will not. For information on how to use a 16-bit grayscale COLORREF in a non-LEADTOOLS function, refer to L_GetPixelColor.

Returns

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

Example

For complete sample code, refer to the FEATURE3 example. This example loads a bitmap and fills it with blue.

 L_INT FillBitmapExample(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 (TEXT("C:\\Program Files\\LEAD Technologies\\LEADTOOLS 15\\Images\\IMAGE1.CMP"), &LeadBitmap, sizeof(BITMAPHANDLE), 0, ORDER_BGR, NULL, NULL);
   if(nRet != SUCCESS)
      return nRet;
   /* Fill the bitmap with blue */
   nRet = L_FillBitmap(&LeadBitmap,RGB(0, 0, 255));
   if(nRet != SUCCESS)
      return nRet;

   nRet = L_SaveBitmap(TEXT("C:\\Program Files\\LEAD Technologies\\LEADTOOLS 15\\Images\\Result.BMP"), &LeadBitmap, FILE_BMP, 24, 0, NULL);
   if(nRet != SUCCESS)
      return nRet;
   if(LeadBitmap.Flags.Allocated)
      L_FreeBitmap(&LeadBitmap);  
   return SUCCESS;
