Example 1 with BufferedImageWriter

use of loci.formats.gui.BufferedImageWriter in project digilib by robcast.

the class BioFormatsDocuImage method writeImage.

@Override

            // copy out file
            ostream.write(dataBuffer, 0, len);
        }
    } catch (IOException e) {

Example 2 with BufferedImageWriter

use of loci.formats.gui.BufferedImageWriter in project bioformats by openmicroscopy.

the class SumPlanes method main.

public static void main(String[] args) throws Exception {
    String id = args[0];
    BufferedImageReader r = new BufferedImageReader();
    System.out.print("Reading " + id);
    r.setId(id);
    int imageCount = r.getImageCount();
    BufferedImage[] images = new BufferedImage[imageCount];
    for (int i = 0; i < imageCount; i++) {
        System.out.print(".");
        images[i] = r.openImage(i);
    }
    r.close();
    System.out.println(" [done]");
    String outId = id + ".tif";
    BufferedImageWriter w = new BufferedImageWriter();
    System.out.print("Writing " + outId);
    w.setId(outId);
    w.saveImage(0, sum(images));
    w.close();
    System.out.println(" [done]");
}
