Hello Batik Users,
I have a weird behaviour with a TIFF transcoder.
I have a Document created by parsing a SVG file. I did time
measurements and saw that the first time when launching the application,
the whole operation takes about 5 seconds. Then, time decreases to 1
second and it stays there.
The rasterization operation is the most time-consuming, and I observed
that the time spent in it decreases about 7 times. Why?!
I am pleased with the behaviour but I fear it hides something dangerous
:-)
Here are the involved code fragments. First call parse, then rasterize.
mDocument is declared at class level like this:
private Document mDocument = null;
public void parse (String fileName) {
try {
String parser = XMLResourceDescriptor.getXMLParserClassName();
SAXSVGDocumentFactory factory = new SAXSVGDocumentFactory(parser);
mDocument = factory.createDocument(fileName);
} catch (IOException ex) {
}
}
public void rasterize (String outputFileName){
byte[] myByteArray;
TIFFTranscoder t = new TIFFTranscoder();
TranscoderInput input = new TranscoderInput(mDocument);
try {
ByteArrayOutputStream ostream = new ByteArrayOutputStream();
TranscoderOutput output = new TranscoderOutput(ostream);
t.transcode(input, output);
ostream.flush();
ostream.close();
myByteArray = ostream.toByteArray();
ByteArrayInputStream istream = new
ByteArrayInputStream(myByteArray);
//read the ARGB TIFF in memory and write it in RGB on the disk
to change the transparency property:
transformImage (istream, outputFileName);
istream.close();
} catch (FileNotFoundException ex) {
} catch (IOException ex) {
} catch (TranscoderException ex) {
}
}
Best Regards,
Felicia
