Question

How can I modify image from java through ImageMagick? Is there any way of doing it?

Answer 1

Use JMagick (docs). Read the documentation. It provides all the functionality of ImageMagick. You may also look into another ImageMagick Java wrapper, im4java.

There is a good starters document for im4java here

Here is an example, I’ve worked out.

/** Typical scaling implementation using JMagick **/
ImageInfo origInfo = new ImageInfo(absPath); //load image info
MagickImage image = new MagickImage(origInfo); //load image
image = image.scaleImage(finalWidth, finalHeight); //to Scale image
image.setFileName(absNewFilePath); //give new location
image.writeImage(origInfo); //save

Edit #1:

If you are wondering for the Jar file of JMagick. Download jMagick tarball, untar it.

$ tar xvzf jmagick-linux-6.4.0-Q32.tar.gz 
./jmagick-6.4.0.jar
./jmagick.jar
./libJMagick-6.4.0.so
./libJMagick.so
