Is it possible to convert eps/tiff files into jpg format image by GD library or any php library? If possible then please show me a way how to start. may be a link to study will be very helpful. If it is not possible to convert eps and tiff files into jpg/gif format then please at least answer that it is not possible.
EPS and TIFF files are not natively supported by PHP. ImageMagik has support for TIFF. I don't recall offhand if it supports EPS however. There are a variety of interfacing scripts available from various venues for ImageMagik.
