Hello everyone
I am working on converting cmyk jpeg images to rgb.
Here I used NvJpg Decoder and I was able to get YCCK Data.
I want to convert this to RGB data.
However, I have a question about nppi’s CMYK_OR_YCCK_JPEG_TO_RGB api during the conversion process.
In the image above, the RED arrow is the result of converting CMYK data to RGB via nppiCMYKOrYCCKToRGB_JPEG_8u_P4P3R_Ctx API.
In the image above, the BLUE arrow is the result of converting YCCK data directly to RGB via nppiCMYKOrYCCKToRGB_JPEG_8u_P4P3R_Ctx.
In both processes, the results are very different from what I expected.
What did I do wrong?
Can someone tell me the conversion process used in the nppiCMYKOrYCCKToRGB_JPEG_8u_P4P3R_Ctx API?
Thank you all for reading this. Have a happy day!
