ImageIO.write bmp does not work

Question

I\'m trying to save an image in bmp format, but it doesn\'t create any file. If I use \"png\" instead, everything works fine. Any ideas?

didn't try but I think the format should be "BMP" and not "bmp" actually. Please try with

ImageIO.write(bi, "BMP", new File("D:\\MyImage.bmp"));

and see what happens.

We can't see how your bi is build.

BufferedImage bufferedImage = new BufferedImage(w,h,BufferedImage.TYPE_INT_RGB);

Is the encodingType is set properly ?

I think your bi is corrupted, that's work perfectly for me.

BufferedImage bi = new BufferedImage(50,50,BufferedImage.TYPE_INT_RGB);
Graphics gd = bi.getGraphics();
gd.drawRect(0, 0, 10, 10);      
try {
    ImageIO.write(bi, "BMP", new File("C:\\test.bmp"));
    ImageIO.write(bi, "PNG", new File("C:\\test.png"));
} catch (IOException e) {
    System.out.println("error "+e.getMessage());
}
