Method Detail

getMimeForRawFlavor

public static java.lang.String getMimeForRawFlavor(ImageFlavor flavor)

Returns the MIME type for a given ImageFlavor if it is from a format that is consumed without being undecoded. If the ImageFlavor is no raw flavor, an IllegalArgumentException is thrown.

Parameters:

flavor - the image flavor

Returns:

the associated MIME type

getSupportedMIMETypes

public java.lang.String[] getSupportedMIMETypes()

Returns an array of MIME types supported by this implementation.

Returns:

the MIME type array

getSupportedFlavors

public ImageFlavor[] getSupportedFlavors(java.lang.String mime)

Returns an array of ImageFlavors that are supported by this implementation for a given MIME type.

Parameters:

mime - the MIME type

Returns:

the ImageFlavor array

newImageLoader

public ImageLoader newImageLoader(ImageFlavor targetFlavor)

Creates and returns a new ImageLoader instance.

Parameters:

targetFlavor - the target image flavor to produce

Returns:

a new ImageLoader instance

isAvailable

public boolean isAvailable()

Indicates whether the underlying libraries needed by the implementation are available.

Returns:

true if the implementation is functional.

isSupported

public boolean isSupported(ImageInfo imageInfo)

Indicates whether the given image (represented by an ImageInfo object) is supported by the loader. By default, implementations return true assuming all images of the supported MIME types can be processed correctly. In some cases, however, an ImageLoader may only support a subset of a format because it offers an optimized way to embed the image in the target format (for example: CCITT compressed TIFF files in PDF and PostScript). For this to work, the preloader must register some information in the ImageInfo's custom objects so the factory can identify if an image may or may not be supported.

Specified by:

isSupported in interface ImageLoaderFactory

Overrides:

isSupported in class AbstractImageLoaderFactory

Parameters:

imageInfo - the image info object

Returns:

true if the image is supported by the loaders generated by this factory
