Package com.idrsolutions.image.emf

Class EmfDecoder

java.lang.Object
com.idrsolutions.image.JDeliImage
com.idrsolutions.image.emf.EmfDecoder
All Implemented Interfaces:
com.idrsolutions.image.Decoder
public class EmfDecoder extends com.idrsolutions.image.JDeliImage implements com.idrsolutions.image.Decoder
Class reads EMF images as BufferedImage Make NO assumptions about the BufferedImage type returned as this may change

Example 1 (Using raw byte data):


 EmfDecoder decoder = new EmfDecoder();
 BufferedImage decodedImage = decoder.read(emfBytes);

Example 2 (Using a File):


 File enfFile = new File("C:\\path\\to\\file\\image.emf");
 EmfDecoder decoder = new EmfDecoder();
 BufferedImage decodedImage = decoder.read(emfFile);
