Constructor Details

SVGImageReader

public SVGImageReader(ImageReaderSpi provider)

Creates an SVGImageReader.

Parameters:

provider - the provider

Method Details

resetMembers

protected void resetMembers()

Description copied from class: ImageReaderBase

Resets all member variables. This method is by default invoked from:

• ImageReaderBase.setInput(Object, boolean, boolean)
• ImageReaderBase.dispose()
• ImageReaderBase.reset()

Specified by:

resetMembers in class ImageReaderBase

dispose

public void dispose()

Overrides:

dispose in class ImageReaderBase

setInput

public void setInput(Object input,
 boolean seekForwardOnly,
 boolean ignoreMetadata)

Description copied from class: ImageReaderBase

Overrides setInput, to allow easy access to the input, in case it is an ImageInputStream.

Overrides:

setInput in class ImageReaderBase

Parameters:

input - the ImageInputStream or other Object to use for future decoding.

seekForwardOnly - if true, images and metadata may only be read in ascending order from this input source.

ignoreMetadata - if true, metadata may be ignored during reads.
