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.
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.
