Removing/disabling some colors.
Please describe your issue and provide steps to reproduce it:
I am looking a way to remove some color from PDF file… for instance for a given PDF file I would like to remove/disable “Magenta” color from CMYK color space and save PDF. Have trouble to find appropriate color space and color component.
Any help is welcome, thanks in advance!

Thank you for contacting Apryse support.
I’m reviewing your request and will get back to you shortly.
Take a look at our ElementEdit sample, it shows ways to looping through every element in a PDF and modifying it, including examples of how to get colour space and removing or changing a specific colour:
Let me know how that works for you and if you have any other questions.
Thanks kmirsalehi, it helped. So there is no “central” place to removing some color component from color space, but have to iterate through all elements.
That’s correct, each element has it’s own graphical state so you need to iterate through each to remove a specific colour.
