Example 56 with java.awt.image

use of java.awt.image in project JMRI by JMRI.

the class LcdClockFrame method scaleImage.

// size of the display window

    //      Ugly hack to force frame to redo the layout.
    //      Without this the image is scaled but the label size and position doesn't change.
    //      doLayout() doesn't work either
