Rasterizer TIFF Compression

[M V <ht...@hotmail.com>]

Hello.  I'm currently using the rasterizer from the DOS prompt to convert 
batches of SVG files to high resolution TIFF format for use in print.  I 
didn't know this before, but apparently the TIFF format used is 
uncompressed.  Is there a way to rasterize the files using LZW compression?

Thanks.

   No (ex-patent issues), but the Tiff encoder we use (from JAI) does support
Deflate compress (similar to LZW - lossless and generally produces smaller files).
We currently don't export a mechanism for turning this on but if you know
anything about Java adding this would be fairly simple.

   You might also consider using PNG which also uses deflate and has some
'predictors' which can help a lot in compression.

   Also if you are generating 'high resolution TIFF' images have you looked
at using the TiledTranscoder from the contrib area?
