EPSTranscoder > Rotate

Hi,


I have got a strange problem while rasterizing in EPS format : Image needs a
rotation and a mirror transformations after processing.
This does not happen with jpeg and png rasterizers.

Any idea ?


Thanks

GR.

Well maybe I should say Transcoder instead of Rasterizer.
I do not use any 3rd party tool. I use only libs coming from batik 1.7b

This is my code.
*********************************
EPSTranscoder epstranscoder = new EPSTranscoder();
if (resolution != null){
   float myvalue = ((2.54f/resolution)*10);
   epstranscoder.addTranscodingHint(
EPSTranscoder.KEY_PIXEL_UNIT_TO_MILLIMETER, myvalue);
}
epstranscoder.transcode(svgInput, imageOutput);
//ko : eps image needs additional transformations
*********************************

I hage got something similar with PNG
*********************************
PNGTranscoder pngTranscoder = new PNGTranscoder();
if (resolution != null){
     float myvalue = ((2.54f/resolution)*10);
     pngTranscoder.addTranscodingHint(
PNGTranscoder.KEY_PIXEL_UNIT_TO_MILLIMETER, myvalue);
     pngTranscoder.addTranscodingHint(
PNGTranscoder.KEY_FORCE_TRANSPARENT_WHITE, transparent);
}
pngTranscoder.transcode(svgInput, imageOutput);
//ok works fine
*********************************

Maybe I forgot someting in the transcoding hints of the EPSTranscoder ?

   Given that PNG and JPEG work I would guess that the problem

   As far as I know Batik doesn't provide an EPS rasterizer.
Are you using some "3rd party" tool or custom code? 

   Given that PNG and JPEG work I would guess that the problem 
is in what ever the EPS part is.
