Hello,

  I am a user of  [VC++/Raster Imaging Pro v15], and the import form is C++ CLIB.

   In my project, I met a question about image processing related to saturation. In order to adjust the "saturation" function, I used the function named as "LBitmap::ChangeSaturation".
   However, the effect is different with the desired effect(PhotoShop effect). How should I do?
   Please confirm the above problem, and thanks in advance.

Aspire,

Can you please tell me how exactly the effect differs between LEADTOOLS and PhotoShop? Can you provide me with sample images that shows the difference in effect? Also, how exactly are you applying the Saturation effect?

If you decided to send me images for comparison, put them in a ZIP or RAR file first.

Aspire,


The only difference is that the
value range is different. This means if you need a similar effect to what
PhotoShop is giving you, you must use larger values when calling our Saturation function.


If want more saturation than the maximum value gives you, simply call the function more than once until you get the result you want.
