Hello,
I use the PDFTranscoder to create a PDF document from SVG, but the quality of the result is bad. I tried it with the pdftranscoder.jar from Batik 1.5/1.5.1 and with the fop.jar (FOP 0.20.5) and the results were different.
Yes, Batik ships with a newer version of the PDF transcoder files.
pdftranscoder: -the colors are a little different
I have not seen this, can you provide sample content?
-the text has no anti-aliasing
This depends on how you have your PDF viewer setup, by default Acrobat doesn't anti-alias text, you can tell it you want it to (Preferences somewhere). I don't think there is currently an option to always output text as paths.
-the opacity seems to be okay
fop: -the colors are okay -the opacity does not work -the text has anti-aliasing
How can I create a pdf document wich looks like the original SVG? The created JPG, PNG and TIFF documents are correct.
It's usually the wrong thing to do but you could just embed a JPEG/PNG in the PDF. The simplest way to do this would be to create a 'small' SVG that consisted just of an image element that referenced the rasterized PNG. Of course when you went to print it the result would probably look a bit blurry.
public static void transcodeSVG2PDF(byte[] svgInput, OutputStream output, Color backgroundColor) throws TranscoderException, IOException { TranscoderOutput transcoderOutput = new TranscoderOutput(output); PDFTranscoder transcoder = new PDFTranscoder(); transcoder.addTranscodingHint(ImageTranscoder.KEY_BACKGROUND_COLOR, backgroundColor); transcoder.transcode(new TranscoderInput( new ByteArrayInputStream(svgInput)), transcoderOutput); output.flush(); }
Thanks! Mathias Kalb
