Class HiDPIScaleUtilities

  • @OpenApiAll
public class HiDPIScaleUtilities
extends com.nomagic.ui.HiDPIScaleUtilitiesInternal
    Utilities to work with various scaling aspects on HiDPI screens.

    These utilities do not have any affect on Mac Retina screens. On Retina screens RetinaUtilities should be used.

    There are two types of scaling factors: system and user. System scaling factor is managed by JVM. If it is enabled - graphics is scaled automatically. System Scaling factor is calculated using Toolkit.getScreenResolution() value. User scaling factor is defined by user supplying jvm argument magicdraw.resolution.scale. For example -Dmagicdraw.resolution.scale=2 means scale ui two times. Both scaling factors has multiplicative relation, ui is scaled by both scaling factors.
