| Paulo | Can anyone point me to hwere will be the best place to make a request for a feature -- the creation of a device that will be able to recognize (and list) the colorspaces of an EPS? | 12:08.34 |
| kens | You can open enhancement requests at our Bugzilla | 12:15.20 |
| | But to be honest, I don't think its something we are likely to do | 12:15.34 |
| | Note that it could not be limited to EPS files either, it would have to cover all input formats (as a device). | 12:16.02 |
| | You could write a PostScript program to 'hook' the colour operators (setgray, setrgbcolor, setcmykcolor, setcolorspace) and report from teh PostScript level | 12:16.42 |
| Paulo | Nice idea! I want something simple. Can you point me to an example of such PS program so I can get started? | 12:27.41 |
| kens | Off the top of my head, no, sorry. | 12:28.04 |
| chrisl | Have a look at: https://stackoverflow.com/questions/16680747/how-can-i-extract-color-values-from-an-eps-file | 12:32.00 |
| kens | <sigh> quoting an answer from me :-) | 12:32.30 |
| Paulo | My question originated with that posting. | 12:32.51 |
| | Would you edit your answer and elaborate further? | 12:33.20 |
| kens | Oh, well that shows you hot to redefine a PostScript operator as a user-supplied procedure. In this case the 'stroke' operator. | 12:33.21 |
| Paulo | Would you edit your answer and elaborate further? | 12:33.46 |
| kens | You would neeed to do similar code to save the original operator and redefine the colour operators in PostScript. That's the setgray, setrgbcolor, setcmykcolor and setcolorspace operators. | 12:34.04 |
| | gray, rgb and CMYK are easy to deal with. setcolorspace you would need to look at the operands to determine what kind of space it is. | 12:34.32 |
