[218]Write a text into an image
By Anonymous on 2004/05/12 04:58:38  Rate
//The following code reads an image, writes a string onto the image and  
 //writes it out as a TIFF file. With small modifications ( changing the  
 //encode parms and compression ) , this code will work for JPEGs or any other  
 //image formats. This code used JAI. 
  
  
  
 ParameterBlock pb = new ParameterBlock (  ) ; 
 RenderedImage ri = JAI.create ( "fileload", filename ) ; 
  
  
  
 PlanarImage image= new RenderedImageAdapter ( ri ) ; 
  
  
 BufferedImage bufImg = image.getAsBufferedImage (  ) ; 
 Graphics2D g2d = bufImg.createGraphics (  ) ; 
 g2d.setColor ( Color.black ) ; 
 g2d.drawString ( "annotation", 50, 200 ) ; 
  
  
 PlanarImage planarImage = PlanarImage.wrapRenderedImage ( bufImg ) ; 
 pb.addSource ( planarImage ) ; 
  
  
 TIFFEncodeParam encodeParam = new TIFFEncodeParam (  ) ; 
 encodeParam.setCompression ( TIFFEncodeParam.COMPRESSION_GROUP4 ) ; 
 encodeParam.setExtraImages ( images.iterator (  )  ) ; 
 OutputStream os = new FileOutputStream ( "bi.tiff" ) ;
