      • getRetinaScaleFactor

        public static float getRetinaScaleFactor()
        Macintosh retina display support for Java 7 and newer.
        Returns:
        1.0 on standard resolution devices and 2.0 for retina screens

      • getUIScaleFactor

        public static float getUIScaleFactor()
        For Windows and Linux this method returns the user defined UI scaling factor. This is done by judging from the size of the UIManager's Label.font and comparing it to the unscaled default (13). Typically this factor is larger than 1.0 on HiDPI devices. For this method to work the Look&Feel must consider the OS provided setting and scale its fonts accordingly (Substance LaF does).
        On the Macintosh this factor is usually 1.0, because HiDPI device support uses a different mechanism (see getRetinaScaleFactor()).
        Returns:
        typically 1.0 or 1.25, 1.5, ...

      • scale

        public static int scale​(int value)
        This is a convenience method that scales the passed int value with getUIScaleFactor() and returns the rounded result.
        Parameters:
        value -
        Returns:

      • scaleRetinaAndUI

        public static int scaleRetinaAndUI​(int value)
        This is a convenience method that scales the passed int value with getUIScaleFactor() and with getRetinaScaleFactor() and returns the rounded result.
        Parameters:
        value -
        Returns:

      • getThemeColor

        public static java.awt.Color getThemeColor​(int no)

      • createIcon

        public static javax.swing.Icon createIcon​(java.lang.String fileName,
                                          int rotation)

      • createDisabledIcon

        public static javax.swing.Icon createDisabledIcon​(java.lang.String fileName,
                                                  int rotation)

      • createImage

        public static java.awt.image.BufferedImage createImage​(java.lang.String fileName)
        Creates an image from the fileName. On HiDPI devices this is a high resolution image. If the current look&feel is dark, then colors are adapted for optimal contrast.
        Parameters:
        fileName -
        Returns:

      • createLaFCompatibleImage

        public static java.awt.image.BufferedImage createLaFCompatibleImage​(java.lang.String fileName)

        Parameters:
        fileName -
        Returns:
