But this all has, in my case, a lot of disadvantages. First, Batik spent a lot of time to process (since in ARGB colorspace) whenever Color is not required for our output. Secondly, Batik spent time to convert the ARGB RenderedImage to GRAY or Bilevel Colorspace when trying to Encode the RenderedImage.
I would need to be able to customize Batik to process in Gray Colorspace. Is it possible easily? What are things/Classes i need to modify to achieve this?
This depends a lot on how you are doing the transcoding. If you are using the TiledTranscoder (which I think you are) then you need to come up with a replacement for batik.gvt.filter.GraphicsNodeRed8bit that uses a gray ColorModel instead of the sRGB ColorModel. You will also need to replace the GraphicsNodeRable8Bit with one that uses your GraphicsNodeRed. This should mostly be cut and paste.
If you are using the JPEG/TIFF transcoders then you should only need to subclass and replace the 'createImage' method.
In doing this there is some chance that everything will fall apart because something in Batik is assuming the destination will have 3/4 bands. I don't think this will happen but it might (especially with filters).
Good luck!
