I am new to IMAGEEN ,

I want to switch the colorspace of a jpg image, from RGB to CMYK

And after that to work with the C, M, Y channels as with the R, G, B
channels respectively

for example , extract histograms per channel

and get CalcAverageCMY ....

Many Thanks

Ohad

Hi

You can convert the pixel format of an image to ieCMYK using TIEBitmap.PixelFormat.

Then you can work with the CMYK pixels using TIEBitmap.Pixels_ieCMYK.

- IECMYK2RGB() and IERGB2CMYK() in imageenio.pas
