How can I open a CMYK tif image and read the pixels CMYK values?

Question

I have search around and can see many questions on converting values but I cant find a library that gives me the CMYK values, I can only see examples that get the RGB values?

If there a library that can open CMYK tif files and do this?

Answer 1

One option is to use LibTiff.Net library (disclaimer: I am one of it's developers). The library can provide access to data in TIFF without conversion of the data.

Following methods might be useful for you:

• Tiff.ReadScanline (generic access to decoded but not converted samples grouped in scanlines)
• Tiff.ReadEncodedStrip (the same as above but for strips)
• Tiff.ReadEncodedTile (the same as above but for tiles)

There are also Getting Started tutorial and some samples.
