MONITOR_DPI_TYPE Enumeration

Identifies the dots per inch (dpi) setting for a monitor.

Syntax

typedef enum MONITOR_DPI_TYPE {
  MDT_EFFECTIVE_DPI,
  MDT_ANGULAR_DPI,
  MDT_RAW_DPI,
  MDT_DEFAULT
} ;

Constants

MDT_EFFECTIVE_DPI The effective DPI. This value should be used when determining the correct scale factor for scaling UI elements. This incorporates the scale factor set by the user for this specific display.
MDT_ANGULAR_DPI The angular DPI. This DPI ensures rendering at a compliant angular resolution on the screen. This does not include the scale factor set by the user for this specific display.
MDT_RAW_DPI The raw DPI. This value is the linear DPI of the screen as measured on the screen itself. Use this value when you want to read the pixel density and not the recommended scaling setting. This does not include the scale factor set by the user for this specific display and is not guaranteed to be a supported DPI value.
MDT_DEFAULT The default DPI setting for a monitor is MDT_EFFECTIVE_DPI.

Remarks

All of these settings are affected by the PROCESS_DPI_AWARENESS of your application
