Question

How to convert images with following extensions jpg, pdf, gif, xls, xlsx, doc, docx, rtf, bmp, jpeg, csv to .TIFF in Java ?

I want to convert all the above mentioned image extensions to .TIFF extension.

Answer 1

Apache Commons Sanselan has support for reading and writing BMP , JPEG/JFIF , TIFF , GIF and PNG from your list.

Apache PDFBox can convert PDF files to images (see PDFToImage code).

Apache POI can read doc , docx , xls and xlsx , but I am not aware of an easy way to convert them to an image (if that is what you would want to do). What you could probably do is make a conversion to a PDF first and then from PDF to an image.

Answer 2

You can use JAI for converting images to TIFF format.
