<html> <head> <meta http-equiv="content-type" content="text/html; charset=ISO-8859-1"> </head> <body bgcolor="#FFFFFF" text="#000000"> I need the "disable antialias" feature because some of my bar codes no longer have sharp edges comparing with the image I drew through Window's DC. I suspect disabling antialias will get the sharp edge back. I also suspect antialias slow things down. My batch processing program generates many images, so some speedup is quite valuable. I tested <tt>cairo_set_antialias(cr, CAIRO_ANTIALIAS_NONE);</tt> It has no effect in my case, and I understand it is just a hint for the back end. I searched the archive and found some messages about "disable subpixel antialiasing" from Jan-2011. It seems that there was no solution at that time, hopefully someone can give an update on the current situation. Suggestions for improving the bar code is also appreciated.
