Java / JAI - save grayscale image

Question

I am trying to keep tiff instead of color gray-scaled. How can i do this? (JAI should be used because it's tiff!)

Many thanks in advance and best regards.

Answer 1

You want to download the JAI Image I / O Tools , which provides ImageIO adapters for JAI. Once you have installed this, it will be smooth.

final BufferedImage in = ImageIO.read(new File("frabozzle.tif")); final BufferedImage out = new BufferedImage( in.getWidth(), in.getHeight(), BufferedImage.TYPE_BYTE_GRAY); out.getGraphics().drawImage(in, 0, 0, null); ImageIO.write(out, "TIFF", new File("graybozzle.tif")); 

Answer 2

Given BufferedImage , you can use the filter() method of ColorConvertOp , as shown in this example .
