the image metadata as a map String -> Object

getImageMimeType

String getImageMimeType(File file)

Returns the mime-type for the given file.

getImageMimeType

String getImageMimeType(Blob blob)

Returns the mime-type for the given Blob

@Deprecated
String getImageMimeType(InputStream in)

Deprecated. since 5.5

Returns the mime-type for the given input stream.

getImageInfo

ImageInfo getImageInfo(Blob blob)

Retrieves the ImageInfo of the Blob that is received as parameter.

The information provided by the ImageInfo, like width, height or format, is obtained using ImageMagick (see http://www.imagemagick.org/script/index.php for more details on ImageMagick).

Returns:

the ImageInfo of a blob

getConfigurationValue

String getConfigurationValue(String configurationName)

Returns the value a configuration which name is received as parameter.

Parameters:

Returns the value a configuration which name is received as parameter. In case no configuration with the specified name was registered, the received defaultValue parameter will be returned.

Parameters:

configurationName - the name of the configuration

defaultValue - the value of the configuration

setConfigurationValue

void setConfigurationValue(String configurationName,
                         String configurationValue)

Sets the value of a configuration which could be used by the ImagingService.

Parameters:
