Hello,

I used CombineImages() function to merge 4 channels(CMYK) image and then to create a color image.
The color image open in Photoshop is normal, But open in Preview (Mac Preview) is negative image?
Why?

Platform : Mac OS 10.6 (Snow Leopard)

Somebody can help me.
Thanks a lot.

Hello guys, In my OS had a dynamic zlib library at /usr/lib (old version), But I don't want to use system level dynamic zlib. So, I compiled ImageMagick with a static zlib, but i confuse It, why ImageMagick always use system level dynamic zlib. My configuration refer to following: ./configure ...

You are provide very useful information!

MagickSetImageColorspace() and MagickSetColorspace()

Your mean is use CombineImages() function. Right?

Dear Master, I know that about API. I encountered a big problem When I using MagickCore and MagickWand's C API. Sometimes I do not understand function and argument's descriptions (It's not clear), So I have to post a question again again again and again!! For example, I try to compose 4 channel ...

About API description??

Dear Master, I'm using CompositeImageChannel to compose CMYK files, But black channel always appear "black" no any image in in. C,M,Y channels are look very well. . . status = CompositeImageChannel(cmykImage, BlackChannel , CopyBlackCompositeOp , srcImage, 0, 0); . . WriteImage(imageInfo, cmykImage ...

Thanks!

If I focus on hardware, Which one to replace can be speedup!!

Thanks
