We would use Inkscape for drawing lithography mask. The document size and the PNG output size is 16384*16384 pixel. The exposure time per pixel is coded in the pixel color (non linear). So we need a PNG export without antialiasing/blur.

Sorry, not possible in Inkscape as of yet. If it's b/w, you can just process it with threshold in any bitmap processor. Otherwise you can export it several times as big as needed and scale down without AA in a bitmap processor.

I have found the getUseAntialias in filedialog.cpp. But I think this is a unused function yet. Is this right?

no idea what this is for

Then I have found in png-write.cpp:

335 // export with maximum blur rendering quality 336 int saved_quality = prefs_get_int_attribute ("options.blurquality", "value", 0); 337 prefs_set_int_attribute ("options.blurquality", "value", 2);

I have set options.blurquality to zero, but this has no effect for the exported png!?

This is only for specifically blurred objects, not for AA.
