I am using batik library for image conversion , I need to convert jpeg/png to tiff format. Can anyone help me on how to do the conversion using batik (preferable) , because i am using the same library for other SVG conversions.
You could probably do PNG - > SVG - > TIFF conversion.
This link should point you in the right direction: http://xmlgraphics.apache.org/batik/tools/rasterizer.html
check the "Examples of using the rasterizer task" section.
Hope this helps.
