6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	40 * to paint using methods such as <code>GC.drawImage()</code>
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	41 * and display on widgets with, for example, <code>Button.setImage()</code>.

6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	43 * If loaded from a file format that supports it, an
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	44 * <code>Image</code> may have transparency, meaning that certain
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	45 * pixels are specified as being transparent when drawn. Examples
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	46 * of file formats that support transparency are GIF and PNG.
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	47 * </p><p>
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	48 * There are two primary ways to use <code>Images</code>.
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	49 * The first is to load a graphic file from disk and create an
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	50 * <code>Image</code> from it. This is done using an <code>Image</code>
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	51 * constructor, for example:
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	52 * <pre>
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	53 * Image i = new Image(device, "C:\\graphic.bmp");
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	54 * </pre>
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	55 * A graphic file may contain a color table specifying which
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	56 * colors the image was intended to possess. In the above example,
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	57 * these colors will be mapped to the closest available color in
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	58 * SWT. It is possible to get more control over the mapping of
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	59 * colors as the image is being created, using code of the form:
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	60 * <pre>
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	61 * ImageData data = new ImageData("C:\\graphic.bmp");
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	62 * RGB[] rgbs = data.getRGBs();
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	63 * // At this point, rgbs contains specifications of all
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	64 * // the colors contained within this image. You may
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	65 * // allocate as many of these colors as you wish by

6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	67 * // create the image:
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	68 * Image i = new Image(device, data);

6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	71 * Applications which require even greater control over the image
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	72 * loading process should use the support provided in class
