[MBS] lcms Questions

Hi.

We are looking at integrating some basic colour management into our application when displaying pictures. I know MBS supports lcms and I would appreciate it if anyone could give me some pointers on how to do this on both Mac & Windows.

1. When displaying RGB TIFF / JPEG images on-screen show them with the embedded profile.

2. Convert all RGB TIFF / JPEG images to sRGB.

3. Convert all CMYK TIFF / JPEG images to sRGB.


Cheers,
Kev.

Well, the TIFF and JPEG plugins can load those pictures. For a RGB image
they can give you a Picture and for CMYK a memoryblock with the data.

That data can be send through the cmtransformMBS object class to
transform it. You should check this examples:

/LCMS/CMYK/CMYK Example
/LCMS/CM image test
