@Farrakh it depends on your linux package manager: check http://www.linuxforums.org/forum/linux-tutorials-howtos-reference-material/64958-how-install-software-linux.html for further help – Zac May 06 '14 at 06:57

It's the same concept as jpeg. One of the "magicks" of the library is that it is largely type independent when writing the code. Try doing it the same way.
If you're attempting to do conversion, maybe try looking here.

String fileName = "storage/sdcard0/aaawatermark/canvas.jpg"; ImageInfo info = new ImageInfo(fileName); MagickImage mainImage = new MagickImage(info); String outFileName = "storage/sdcard0/aaawatermark/canvasaaa.png"; mainImage.setImageFormat("png"); mainImage.setFileName(outFileName); mainImage.writeImage(info); – Farrakh May 06 '14 at 06:43
