org.docbook.extensions.xslt20.ImageIntrinsics

All Implemented Interfaces:

java.io.Serializable

public class ImageIntrinsics
extends net.sf.saxon.lib.ExtensionFunctionDefinition

Saxon extension to obtain the intrinsic size of images. This class provides a Saxon extension to find the intrinsic size of images.

The function attempts to load the image with the AWT Image toolkit. If that fails, it searches for a bounding box (present in, e.g., EPS and PDF images).

If the image can be loaded or a bounding box is found, the width and height of the image are returned.
