public static final org.eclipse.swt.graphics.Color	getBoundedShade(org.eclipse.swt.graphics.Color original, int delta) Gets a new SWT color that has been uniformly added with delta If the a RGB value goes out of bounds, the delta will be applied negatively param original Original color param delta Delta in 8bit RGB values return New color final RGB newRGB = new RGB( getBoundedShade(original.getRed(), delta), getBoundedShade(original.getGreen(), delta), getBoundedShade(original.getBlue(), delta) ); return new Color(Display.getDefault(), newRGB);
private static int	getBoundedShade(int origValue, int delta) Gets a 8bit RGB value that has been added with delta If the RGB value goes out of bounds, the delta will be applied negatively param origValue Original RGB value param delta Delta return New RGB value int result = origValue + delta; if(result > 255) { result = origValue - delta; if(result < 0) { result = origValue; } } else if(result < 0) { result = origValue - delta; if(result > 255) { result = origValue; } } return result;
public static final org.eclipse.swt.graphics.Color	getShade(org.eclipse.swt.graphics.Color original, int delta) Gets a new SWT color that has been uniformly added with delta There is range checking such that the new RGB values are 0 <= x <= 255 param original Original color param delta Delta in 8bit RGB values return New color final RGB newRGB = new RGB( Math.min(255, Math.max(0, original.getRed() + delta)), Math.min(255, Math.max(0, original.getGreen() + delta)), Math.min(255, Math.max(0, original.getBlue() + delta)) ); return new Color(Display.getDefault(), newRGB);
