Hello, Is is still true that exported PNGs will always have antialiasing? ( http://wiki.inkscape.org/wiki/index.php/FAQ#How_to_suppress_antialiasing.3F ) Maintaining the number of colors in the exported bitmap requires the Cairo renderer, right?
I've never seen a request for software to not use AA :) How are you finding the AA a problem?
A couple of friends manufacture jewelry using software which reads a special 2D image and drives a milling machine. The color of each pixel in the drawing signifies the depth of the cut at that point, so any artwork with too many colors will result in bad parts. Antialiased images must be cleaned up before being sent to the mill. If, for example, I create an orange oval with a black border, I just want 2 colors in the PNG for 2 levels of cut in the physical part.
I'd like to have a workflow like this: design in Inkscape, export to PNG, import in milling application, cut stuff.
A way around the lack of 'disable AA' option would be to export the image at a super resolution then resize it down in your prefered raster application, making sure to not 'resample' the image. In photoshop you would use the setting 'Nearest Neighbour'.
Yup, there are ways in image editors to reduce colors, but I was hoping to skip this step in the process.
Thanks, John
