I have spent some time investigating this in order to ask intelligent
questions but I give up, here goes.
I use Gimp for photography and as pre-press for presentations and
web-sites. I am retired from a career of medical image processing, so
I have a history and a library of C++ image manipulation routines.
I would like some new tools in Gimp and I've searched plug-ins and
scripts. My first problem is that I am not comfortable that the tools
I want don't exist rather than I just haven't found them yet.
What I'd like to do is:
- Rotate by an arbitrary angle. I've scanned an image but the page
was not square in the scanner or camera. The best way to do this is to
draw a line on the edge of the page and have a command that rotates it
to horizontal or vertical. The algorithm is well defined and easy
(except for indexed color images).
- Draw arrows and shapes over an image (new vector layer). I found
a shape drawing plugin that is fine except you fill in a form instead
of draw the outline with a cursor, and it doesn't use the pen defined
in the main window.
My questions:
- Do plug-ins like this already exist?
- Would you write these as core, plug-ins, or scripts?
I did download and build 2.7.1 from sources and have a NetBeans project
working for development, I've been using my compiled version. I'm
exploring the sources and while I'm familiar with the algorithms for
what I want to do, I have a long way to go figuring out where to hook
in. I'd appreciate advice on documentation, and source modules to read.
Sorry for the newbie questions to the list.
Joe
