Hi,
We have a huge svg of size
<svg width="3750" height="12245" xmlns="http://www.w3.org/2000/svg";>
How to optimse the below code for optimum memory.. say it should not
take x times more memory than width etc.. i.e in case the api allows
writing line by line of slice by slice converstion rather than entire
width x height x y bytes metrics etc. This way, I hope memory
requirements can be as low as possible through slice or line by line
writing approach to give infinate size svg images conversion.
The code used is
TranscoderInput bInputSVG =newTranscoderInput(lInputReader);
TranscoderOutput bOutputPNG =newTranscoderOutput(lOutputStream);
Transcoder bTranscoder = aTranscoderExt.getTranscoder();
bTranscoder.addTranscodingHint(ImageTranscoder.KEY_PIXEL_UNIT_TO_MILLIMETER,newFloat(0.256));
bTranscoder.addTranscodingHint(ImageTranscoder.KEY_BACKGROUND_COLOR,
Color.white);
bTranscoder.addTranscodingHint(JPEGTranscoder.KEY_QUALITY,newFloat(1.0));
//bTranscoder.addTranscodingHint(ImageTranscoder.KEY_WIDTH, new
Float(svgWidth));
bTranscoder.transcode(bInputSVG, bOutputPNG);
but we are getting out of memory error

Process finished with exit code -1
Any pointers to optimum api usage for least memory irrespective of svg
image sizes would help a lot.
