- changing the Pantone color. This is easy to do as all that is required is to change the ColorSpace key in the page dictionary.
True, if the color is referenced from page content. But keep in mind that content can also be in Xobjects, Patterns, etc.
- changing the tint from 100% to 40%, for example, is trickier. It requires parsing the content to look for the the colorspace setting and changing the tint. It's some work but comparing to text extraction it's a ride in the park.
Yes, but you also need to keep a state stack to make sure you are changing the right ops.
