I am currently using Batik as part of a workflow to print badges for a convention. I have a java desktop application which:
1. polls a web server for badges to print 2. retrieves the data (type, template name, person's name, id, etc...) 3. loads an appropriate SVG template 4. Uses ZXing to generate a code-128 barcode and an QR code 5. Loads the appropriate picture for the badge 6. converts the barcode and picture PNGs into data: urls 7. find the appropriate elements in the svg dom and replaces the dummy images with the picture and barcode data: urls 8. sets the batik transcoder output resolution 9. rasterizes the svg to a png file 10. sends the png to a photo printer The problem I am having is that resulting badge png has artifacts in the barcodes. They're either antialiasing or scaling artifacts. This makes the barcode a little hard to scan with readers and slowed down our registration system. Does anyone have any suggestions on how I can keep the barcode images as crisp black and white images inside the full color badge? Thanks, Robert
