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

setCheckCommand

public void setCheckCommand(org.alfresco.util.exec.RuntimeExec checkCommand)

Sets the command that must be executed in order to retrieve version information from the converting executable and thus test that the executable itself is present.

Parameters:

checkCommand - command executer to retrieve version information

getVersionString

public String getVersionString()

Gets the version string captured from the check command.

Returns:

the version string

afterPropertiesSet

public void afterPropertiesSet()

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

Specified by:

afterPropertiesSet in interface org.springframework.beans.factory.InitializingBean

Overrides:

afterPropertiesSet in class AbstractImageMagickContentTransformerWorker

transformInternal

protected void transformInternal(File sourceFile,
                                 String sourceMimetype,
                                 File targetFile,
                                 String targetMimetype,
                                 TransformationOptions options)
                          throws Exception

Transform the image content from the source file to the target file

Specified by:

transformInternal in class AbstractImageMagickContentTransformerWorker

Parameters:

sourceFile - the source of the transformation

sourceMimetype - the mimetype of the source of the transformation

targetFile - the target of the transformation

targetMimetype - the mimetype of the target of the transformation

options - the transformation options supported by ImageMagick

Throws:

Exception

getImageMagickVersionNumber

protected String getImageMagickVersionNumber()

isAlphaOptionSupported
