Examples of javax.imageio.metadata.IIOInvalidTreeException

javax.imageio.metadata.IIOInvalidTreeException
An IIOInvalidTreeException is thrown when an attempt by an IIOMetadata object to parse a tree of IIOMetadataNodes fails. The node that led to the parsing error may be stored. As with any parsing error, the actual error may occur at a different point that that where it is detected. The node returned by getOffendingNode should merely be considered as a clue to the actual nature of the problem. @see IIOMetadata#setFromTree @see IIOMetadata#mergeTree @see IIOMetadataNode
