You can draw the image with a scale of 72 / 200, in other words: double dpi = 200; // you’ll want to fetch this from the tiff content.drawImage(image, x, y, image.getWidth() * 72 / dpi, image.getHeight() * 72 / dpi; — John --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
