Create image from pixel array in java

Question

Here is my snippet. My original array is a[3][][] and the rgb values are stored in there I want to create a new image from them. The last line of the following code results in symbol not found.

BufferedImage img=newBufferedImage(bi.getWidth(),bi.getHeight(),BufferedImage.TYPE_INT_RGB);
for(int r=0; r<bi.getHeight(); r++)
    for(int c=0; c<bi.getWidth(); c++)
    {
        int red=a[0][r][c];
        int green=a[1][r][c];
        int blue=a[2][r][c];
        int rgb = (red << 16) | (green << 8) | blue;
        img.setRGB(c, r, rgb);
    }
ImageIO.write(img,"jpg", "abc.jpg");

Any suggestions?

You are passing the wrong arguments to ImageIO.write() . From the docs , here are the 3 possibilities:

write(RenderedImage im, String formatName, File output) 
write(RenderedImage im, String formatName, ImageOutputStream output) 
write(RenderedImage im, String formatName, OutputStream output)

If you want to write the image to a file called abc.jpg , maybe try:

ImageIO.write(img, "jpg", new File("abc.jpg");
