How to convert .pdf to .png

Question

Using ImageMagick I can convert any pdf document into images by using command "convert":

convert abc.pdf abc.png

This will convert all pdf pages to png images.

How can I implement this using PHP or Java so that I can provide this functionality on my website to enable users to read books online as Google Books does.

You could consider executing ImageMagick from within Java or PHP if possible — Pekka, Sep 30 '10 at 19:13

There is a Java API for ImageMagick called JMagick.

Here is a list of available ImageMagick APIs for various languages.

You could use Java and the pdf-renderer library. Look at this post.

In Java you can call Ghostscript from the command line. Ghostscript is freely available.

ProcessBuilder processBuilder = new ProcessBuilder("C:\\Programme\\gs\\gs9.00\\bin\\gswin32c.exe", "-dSAFER", "-dBATCH", "-dNOPAUSE", "-sDEVICE=pngalpha", "-r300", "-sOutputFile=C:\\TemplateEditor\\AdGenXTest\\Testdaten\\ActualPNGs\\" + fileName + ".png", "C:\\TemplateEditor\\AdGenXTest\\Testdaten\\ActualPDFs\\" + fileName + ".pdf");

processBuilder.start();

Executing a process from Java is a bit wonky, and there are better in-Java ways to do this -- Apache PDFBox, Aspose, Java SE ImageIO – Don Cheadle Feb 13 '15 at 12:24
