Enhances an images contrast, edges, and density range for use in Computed Radiography (CR), in a way that all relevant image features are rendered with an appropriate level of visibility.
Parameter |
Description |
||
pBitmap |
Pointer to the bitmap handle. |
||
uContrast |
Amount of contrast enhancement. |
||
uEdgeLevels |
Number of levels used in edge enhancement. |
||
uEdgeCoeff |
Degree of edge enhancement. |
||
uLatitudeLevels |
Number of levels used in latitude reduction. |
||
uLatitudeCoeff |
Degree of latitude reduction. |
||
uFlags |
Value that determine the type of filter that will be used when applying the MultiScale enchancment filter, one or more flag can be used. Possible values are: |

Flags |
Meaning | |
|
MSE_GAUSSIAN |
[0x0000] Uses Gaussian filter. | |
|
MSE_RESAMPLE |
[0x0001] Uses Resmaple filter. | |
|
MSE_BICUBIC |
[0x0002] Uses Bicubic filter. | |
|
MSE_NORMAL |
[0x0003] Uses Normal filter. | |
|
MSE_EDGEENH |
[0x0010] Adds the latitude reduction option. When this flag is set, the uLatitudeLevels and uLatitudeCoeff parameters will be used. | |
|
MSE_LATRED |
[0x0020] Adds the edge enhancement option. When this flag is set, the uEdgeLevels and uEdgeCoeff properties will be used. |
Returns
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Comments
It also can process the whole image or a region of the image. If a bitmap has a region, the effect is applied only to the region.
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
This example loads a bitmap and applies multiscale enhancement.
L_INT MultiScaleEnhancementBitmapExample(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("IMAGE1.CMP")), &LeadBitmap, sizeof(BITMAPHANDLE), 0, ORDER_BGRORGRAY, NULL, NULL); if(nRet !=SUCCESS) return nRet; // Apply multiscale enhancement nRet = L_MultiScaleEnhancementBitmap(&LeadBitmap, 2000, 4, MSE_DEFAULT , 0, 0, MSE_GAUSSIAN | MSE_EDGEENH); 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; }
