Autolevel, Veriation, Selective Color

Nice to meet you

I don't speak English well.. sorry...

I wish..

Same PhotoShop effects.

autolevel, Veriation, Selective color.;

I use leadtool 14.5 version and

VB6. ActiveX controls.

-------------- reference ------------------
I have looked at the code and it does not call any extra functions before calling the AutoColorLevel command. I'll give you the parameters it uses for VB 6. Give these parameters a try and it should give you the same results as the demo. If the defaults do not give you the results you want, consult the help file for explanations on what the values mean so you can try different settings and flags.

RasterProc.AutoColorLevel LEADRasterView1.Raster, DEFAULT_BLACK_CLIP, DEFAULT_WHITE_CLIP, AUTO_LEVEL

---------------------

what is "RasterProce" ????

please help me..

Thanks

It is true that the RasterProc.AutoColorLevel method will do the same job as the Auto Level of Photoshop.  RasterProc
is an instance of our Raster Process COM object which contains the
image processing methods.  I recommend that you use the COM
objects instead of the ActiveX because the new  image processing methods added to LEADTOOLS were not added to the ActiveX.

For the Selective Color command, try the SelectiveColor method.


As for the Variations command, there is no equivalent method in
LEADTOOLS.  However, according to the documentation of this
command (in Photoshop), it is a combination of color balance, contrast
and saturation commands.  In LEADTOOLS, you can try a combination of the BalanceColors, ColorIntensityBalance, Contrast and Saturation methods to acheive something similar.
