Method Detail

getScaled16x16Icon

@CheckForNull
public static ResizableIcon getScaled16x16Icon(@CheckForNull
                                                             ResizableIcon icon)

Return scaled to 16x16 icon for a given icon. Scaling factor is taken into account, so in scaled environment icon size will be scaled by a scale factor. Scaled icons are cached using WeakReferences.

Parameters:

icon - icon

Returns:

scaled icon

getNonScaledIcon

@CheckForNull
public static ResizableIcon getNonScaledIcon(@CheckForNull
                                                           ResizableIcon icon,
                                                           int size,

Return icon scaled down to a given size. Scaled icons are cached using WeakReferences.

Parameters:

icon - icon

Returns:

icon of given size
