CMYK RGB detection

Hi! I try to detect if an image file is CMYK or RGB. I need to check uploaded files for printability. I used to do this simply with PHP (getimagesize) checking the channels. But I could not find a simple way to get this with uploaded files on Cloudinary. I was trying to get this information within the 'image_metadata'. But there are no save or default key/values for the color mode. I can parse all values for specific strings - but that's just a dirty and inaccurate hack. Any ideas to this issue?

  Thank you for this link. Unfortunately I can not see how to detect if the uploaded image is saved as CMYK.

  It's on our roadmap to support detection of CMYK/RGB. We will update once it's available.

  UPDATE - You can now get the colorspace information together with the image metadata. To get the image metadata please set image_metadata to true on the upload API, or by getting details of a single resource on the Admin API.
