!HD
Controls the DPI scaling on high resolution displays. Use this when you display a PV-WAVE Widget application with non-standard fonts and you notice that the text is too large or too small relative to the widget where the text is displayed. If the text extends beyond the bounds of the widget, select a larger scaling percentage to make PV-WAVE allow more space in the widget for the text. Conversely, if PV-WAVE has allocated too much space in the widget for the text, select a smaller scaling percentage.
!HD can be set to the following:
*0 — No scaling occurs. This is the default.
*1 — Enables auto scaling from detected display information.
*percentage — Set a custom DPI percent setting for more precise control. For example a value of 100 percent corresponds to a DPI setting of 96.
!HD is set to 0 by default.
For more information on DPI scaling, see Display Sizes in the PV‑WAVE Application Developer’s Guide.
