Servlets inheriting from this class need to implement getDom(HttpServletRequest req, HttpServletResponse res) which returns a SPDocument.

Use the class like this:

 ImageInfo ii = new ImageInfo();
 ii.setInput(in); // in can be InputStream or RandomAccessFile
 ii.setDetermineImageNumber(true); // default is false
 if (!ii.check()) {
 System.err.println("Not a supported image file format.");
 } else {
 System.out.println(ii.getFormatName() + ", " + ii.getMimeType() + 
 ", " + ii.getWidth() + " x " + ii.getHeight() + " pixels, " + 
 ii.getBitsPerPixel() + " bits per pixel, " + ii.getNumberOfImages() +
 " image(s).");
 }
 

 java ImageInfo *.jpg *.png *.gif
 

 cat image.jpg | java ImageInfo
 

Known limitations:

• When the determination of the number of images is turned off, GIF bits per pixel are only read from the global header. For some GIFs, local palettes change this to a typically larger value.

This class is an abstraction of a servlet request.
