protected RemoteTransformerClient remoteTransformerClient

Deprecated.

Constructor Detail

AbstractImageMagickContentTransformerWorker

public AbstractImageMagickContentTransformerWorker()

Deprecated.

Method Detail

isAvailable

public boolean isAvailable()

Deprecated.

Description copied from interface: ContentTransformerWorker

Checks if this worker is available.

Specified by:

isAvailable in interface ContentTransformerWorker

Returns:

Returns true if the transformer is functioning otherwise false

setAvailable

protected void setAvailable(boolean available)

Deprecated.

Make the transformer available

Parameters:

available - boolean

setRemoteTransformerClient

public void setRemoteTransformerClient(RemoteTransformerClient remoteTransformerClient)

Deprecated.

Sets the optional remote transformer client which will be used in preference to a local command if available.

Specified by:

setRemoteTransformerClient in interface ContentTransformerWorker

Parameters:

remoteTransformerClient - may be null;

remoteTransformerClientConfigured

public boolean remoteTransformerClientConfigured()

Deprecated.

Specified by:

remoteTransformerClientConfigured in interface ContentTransformerWorker

Returns:

true if ther worker is using a remote server.

afterPropertiesSet

public void afterPropertiesSet()

Deprecated.

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

If initialization is successful, then autoregistration takes place.

Specified by:

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

isSupported

public static boolean isSupported(String mimetype)

Deprecated.

Some image formats are not supported by ImageMagick, or at least appear not to work.

Parameters:

mimetype - the mimetype to check

Returns:

Returns true if ImageMagic can handle the given image format

isTransformable

public boolean isTransformable(String sourceMimetype,
                               String targetMimetype,
                               TransformationOptions options)

Deprecated.

Supports image to image conversion, but only if the JMagick library and required libraries are available.

Specified by:

isTransformable in interface ContentTransformerWorker

getComments

public String getComments(boolean available)

Deprecated.

Description copied from class: ContentTransformerHelper

Overridden to supply a comment or String of commented out transformation properties that specify any (hard coded or implied) supported transformations. Used when providing a list of properties to an administrators who may be setting other transformation properties, via JMX. Consider overriding if {link AbstractContentTransformerLimits.isTransformableMimetype(String, String, TransformationOptions) or ContentTransformerWorker.isTransformable(String, String, TransformationOptions) have been overridden. See ContentTransformerHelper.getCommentsOnlySupports(List, List, boolean) which may be used to help construct a comment.

Specified by:

getComments in interface ContentTransformerWorker

Overrides:

getComments in class ContentTransformerHelper

Parameters:

available - indicates if the transformer has been registered and is available to be selected. false indicates that the transformer is only available as a component of a complex transformer.

Returns:

one line per property. The simple transformer name is returned by default as a comment.
