Note: nohalo1 still not working. It is producing a bad image, and I am looking into this problem. First, I am assuming the new filter will use an existing filter as a template. For nohalo1, I used sharp. Ensure that ALL code references to sharp are changed to nohalo1 in both the .c and .h files. A simple search/replace usually does the trick. But just double-check, I had problems earlier today with this. The next step is to add nohalo1.c and .h to the file list in MakeFile.am. Next, pick an arbitrary existing filter (yafr for example) and use this name as a reference. In the following files: gegl-buffer-access.c gegl-buffer.c gegl-buffer.h gegl-sampler.c Search for occurrences of "yafr", and add a corresponding entry for the new filter (nohalo1 in this case). Overall it is very trivial now that I figured out the steps. I'll post again here if I find out any more info. Once nohalo1 works I'll need to figure out the git/bugzilla process.
