L_TissueEqualizeBitmap

#include "l_bitmap.h"

L_LTIMGCOR_API L_INT EXT_FUNCTION L_TissueEqualizeBitmap(pBitmap, uFlags)

Performs equalization between the hard tissue and the soft tissue in X-ray images, resulting in better quality for better interpretation and understanding of the image.

Parameters

pBITMAPHANDLE pBitmap

Pointer to the bitmap handle referencing the bitmap to perform the equalization operation on.

L_UINT uFlags

Flags that indicate the type of processing. Possible values are:

Value Meaning
TISSUEEQUALIZE_INTENSIFY [0x00000002] Performs tissue equalization with contrast intensification.
TISSUEEQUALIZE_SIMPLIFY [0x00000001] Performs tissue equalization with simplification of intensity values across the image.

Returns

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

Comments

If the bitmap has a region, the effect will be applied on the region only; otherwise the whole image will be processed.

This function supports DICOM images.

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.

Required DLLs and Libraries

Platforms

Win32, x64, Linux.

Example

This example loads a bitmap and applies the Tissue Equalization on it

L_INT TissueEqualizeExample(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\\Image3.cmp")),  
      &LeadBitmap, sizeof(BITMAPHANDLE), 0, 
      ORDER_BGR, NULL, NULL); 
   if(nRet != SUCCESS) 
      return nRet; 
 
   //Apply Tissue Equalize filter with Intensify option 
   nRet = L_TissueEqualizeBitmap(&LeadBitmap, TISSUEEQUALIZE_INTENSIFY); 
   if(nRet != SUCCESS) 
      return nRet; 
 
   //free bitmap  
   if(LeadBitmap.Flags.Allocated)   
      L_FreeBitmap(&LeadBitmap); 
   return SUCCESS; 
 
}
