Image processing: Auto Level, Auto Color, Auto Contrast ...

I like one of the functions in Adobe PhotoShop: Auto Level. How can I achieve that using LeadTools?

Thanks!

Hello,

What is the programming interface (COM, OCX, API, etc.) you are using?

However, LEADTOOLS supports the AutoLevel functionality in our Raster Pro and above toolkits:

=========================
AutoLevel functionality:
=========================
1. If you are using the API programming interface, you can use the L_AutoColorLevelBitmap function to implement the AutoLevel feature as shown below:
-----------------------------------------
nRet = L_AutoColorLevelBitmap (&pData->LeadBitmap, NULL, DEFAULT_BLACK_CLIP, DEFAULT_WHITE_CLIP, AUTO_LEVEL);
-----------------------------------------

For more information, you can refer to the "LEADTOOLS Main API Help file, Version 14" and read the following topic:
- L_AutoColorLevelBitmap
 
2. If you are using the COM programming interface, you can use the AutoColorLevel method (ILEADRasterProcess) to implement the AutoLevel feature as shown below:
-----------------------------------------
Dim RasterProc As New LEADRasterProcess
RasterProc.AutoColorLevel LEADRasterView1.Raster, 50, 50, AUTO_LEVEL
-----------------------------------------

 
For more information, you can refer to the following topic in the "LEADTOOLS Main COM Object Help file":
- AutoColorLevel method (ILEADRasterProcess)
