Method Detail

setExecuter

public void setExecuter(org.alfresco.util.exec.RuntimeExec executer)

Set the runtime command executer that must be executed in order to run ImageMagick. Whether or not this is the full path to the convertCommand or just the convertCommand itself depends the environment setup.

The command must contain the variables ${source} and ${target}, which will be replaced by the names of the file to be transformed and the name of the output file respectively.

    convert ${source} ${target}
 

Parameters:

executer - the system command executer

init

public void init()

Checks for the JMagick and ImageMagick dependencies, using the common transformation method to check that the sample image can be converted.

Overrides:

init in class AbstractImageMagickContentTransformer

transformInternal

protected void transformInternal(java.io.File sourceFile,
                                 java.io.File targetFile,
                                 TransformationOptions options)
                          throws java.lang.Exception
