If a GIF defines a background color, -as many animated GIFs do, then selecting <strong>Background</strong> will use the GIF's background color. -If the image has transparency, which is possible with images of type GIF, PNG, and ICO, then selecting <strong>Display Mask</strong> will draw the image's transparency -mask to the right of the image. You can change the background color of the ImageAnalyzer in order to see the transparency work. -To turn off transparency, deselect <strong>Display Transparency</strong>. -After an image is loaded, it can be scaled with the <strong>Scale</strong> combo, or have alpha transparency applied to it using the <strong>Alpha-K</strong> combo -and <strong>Alpha</strong> menu. <strong>File</strong> > <strong>Reopen</strong> restores the scaling and alpha attributes to their default values and reloads the current image file. -If the image has transparency, -<strong>File</strong> > <strong>Save Mask As...</strong> can be used to save the image's transparency mask. -</p> -<p> -When SWT loads an image file, an instance of <code>org.eclipse.swt.graphics.ImageData</code> is created (though in the case of an ICO file or -multi-image GIF an array of <code>ImageData</code> instances is created). The ImageAnalyzer displays all of the data stored in the <code>ImageData</code> -instance(s) for the currently loaded image file, including the pixel data. Hovering over a pixel in the image display will show the RGB -color data for that pixel. For certain images, particularly animated GIFs, additional data is stored in the <code>org.eclipse.swt.graphics.ImageLoader</code> -instance that is used to load the image. The ImageAnalyzer displays this data as well. -</p> - -<h3>Running the example</h3> - -<p> -Follow the <a href="swt_manual_setup.html">SWT standalone examples setup</a> -instructions to install and run the example from your workspace. -</p> -<p> -The "Main" class is <code>org.eclipse.swt.examples.imageanalyzer.ImageAnalyzer</code>. -</p> -<p> -This example can also be run using the <a href="swt_launcher_ex.html">Example Launcher</a>. -Select the <strong>Image Analyzer</strong> item from the <strong>Standalone</strong> category and click <strong>Run</strong>. -</p> - -</body> -</html> |
