5f2e72114476 Image in work, this revision does not compile Frank Benoit <benoit@tionex.de> parents: diff changeset	52 * There are two primary ways to use <code>Images</code>.
5f2e72114476 Image in work, this revision does not compile Frank Benoit <benoit@tionex.de> parents: diff changeset	53 * The first is to load a graphic file from disk and create an
5f2e72114476 Image in work, this revision does not compile Frank Benoit <benoit@tionex.de> parents: diff changeset	54 * <code>Image</code> from it. This is done using an <code>Image</code>
5f2e72114476 Image in work, this revision does not compile Frank Benoit <benoit@tionex.de> parents: diff changeset	55 * constructor, for example:
5f2e72114476 Image in work, this revision does not compile Frank Benoit <benoit@tionex.de> parents: diff changeset	56 * <pre>
5f2e72114476 Image in work, this revision does not compile Frank Benoit <benoit@tionex.de> parents: diff changeset	57 * Image i = new Image(device, "C:\\graphic.bmp");
5f2e72114476 Image in work, this revision does not compile Frank Benoit <benoit@tionex.de> parents: diff changeset	58 * </pre>
5f2e72114476 Image in work, this revision does not compile Frank Benoit <benoit@tionex.de> parents: diff changeset	59 * A graphic file may contain a color table specifying which
5f2e72114476 Image in work, this revision does not compile Frank Benoit <benoit@tionex.de> parents: diff changeset	60 * colors the image was intended to possess. In the above example,
5f2e72114476 Image in work, this revision does not compile Frank Benoit <benoit@tionex.de> parents: diff changeset	61 * these colors will be mapped to the closest available color in
5f2e72114476 Image in work, this revision does not compile Frank Benoit <benoit@tionex.de> parents: diff changeset	62 * DWT. It is possible to get more control over the mapping of
5f2e72114476 Image in work, this revision does not compile Frank Benoit <benoit@tionex.de> parents: diff changeset	63 * colors as the image is being created, using code of the form:
5f2e72114476 Image in work, this revision does not compile Frank Benoit <benoit@tionex.de> parents: diff changeset	64 * <pre>
5f2e72114476 Image in work, this revision does not compile Frank Benoit <benoit@tionex.de> parents: diff changeset	65 * ImageData data = new ImageData("C:\\graphic.bmp");
5f2e72114476 Image in work, this revision does not compile Frank Benoit <benoit@tionex.de> parents: diff changeset	66 * RGB[] rgbs = data.getRGBs();
5f2e72114476 Image in work, this revision does not compile Frank Benoit <benoit@tionex.de> parents: diff changeset	67 * // At this point, rgbs contains specifications of all
