Java™ Media APIs: Cross-Platform Imaging, Media, and Visualization

ch5ImageMetadata

This is the class used to hold the image metadata (see Listing 5.9). For reading, its values are taken from the input stream. For writing, its values must be set by the application. The DTD for this class is the following:

<!ELEMENT ch5.imageio.ch5image_1.0 (imageDimensions)>
<!ATTLIST imageDimensions
    imageWidth   CDATA  #REQUIRED
    imageHeight  CDATA  #REQUIRED
>

As was true for the ch5StreamMetadata class, this is a very minimal set of metadata used for illustrative purposes, and in practice these classes will be much more complicated.
