Sometimes I come across questions on general issues with using graphics software that are tagged photoshop, illustrator, or mention these applciations in the question body, However, solutions to the issue may be identical on many alternative applications, namely open source counterparts like gimpor inkscape, or even command line applications such as imagemagick.
In the past I have refrained from answering if a question appears to be specific to Adobe products; it seems an answer regarding other software would make little sense. This is not always the case. Occasionally, an alternative may even give better results or be faster at doing the issue specified.
Quite often, steps involved for getting any desired result differ only in the names of the tools but not so much in the procedures involved. In these cases, I sometimes still write an answer but I always feel a bit uncomfortable about it as the OP may be looking for Photoshop/Illustrator solutions only.
Am I welcome to do this? Are there circumstances where adding an additional tag to the question may be a good idea (I haven't done this so far)?
