The DpiHelper type exposes the following members.

Properties

	Name	Description
	BitmapScalingMode	Gets the BitmapScalingMode algorithm to be used for resizing images in WPF. This allows the shell to control the algorithm depending on the dpi zoom scale, and allows the user to override it via registry settings like General\BitmapScalingXXX = (BitmapScalingMode)value, with XXX the zoom factor in percents, e.g. BitmapScaling150, etc.
	DeviceDpiX	Microsoft internal use only.
	DeviceDpiY	Microsoft internal use only.
	DeviceToLogicalUnitsScalingFactorX	Microsoft internal use only.
	DeviceToLogicalUnitsScalingFactorY	Microsoft internal use only.
	ImageScalingMode	Gets the ImageScalingMode algorithm to be used for resizing images in WinForms/Win32. This allows the shell to control the algorithm depending on the dpi zoom scale, and allows the user to override it via registry settings like General\ImageScalingXXX = (ImageScalingMode)value, with XXX the zoom factor in percents, e.g. ImageScaling150, etc.
	IsScalingRequired	Determines whether scaling is required when converting between logical-device units.
	LogicalToDeviceUnitsScalingFactorX	Microsoft internal use only.
	LogicalToDeviceUnitsScalingFactorY	Microsoft internal use only.
	TransformFromDevice	Microsoft internal use only.
	TransformToDevice	Microsoft internal use only.

Methods

	Name	Description
	CreateDeviceFromLogicalImage(Icon, ImageScalingMode)
	CreateDeviceFromLogicalImage(Image, ImageScalingMode)	Creates and returns a new bitmap or metafile scaled for the device units. When displayed on the device, the scaled image will have same size as the original image would have when displayed at 96dpi.
	CreateDeviceFromLogicalImage(ImageList, ImageScalingMode)	Creates and returns a new bitmap or metafile scaled for the device units. When displayed on the device, the scaled image will have same size as the original image would have when displayed at 96dpi.
	CreateDeviceFromLogicalImage(Bitmap, Size, ImageScalingMode)	Creates and returns a new bitmap or metafile scaled for the device units. When displayed on the device, the scaled image will have same size as the original image would have when displayed at 96dpi.
	CreateDeviceFromLogicalImage(Image, Color, ImageScalingMode)	Creates and returns a new bitmap or metafile scaled for the device units. When displayed on the device, the scaled image will have same size as the original image would have when displayed at 96dpi.
	CreateDeviceFromLogicalImage(ImageList, Color, ImageScalingMode)	Creates and returns a new bitmap or metafile scaled for the device units. When displayed on the device, the scaled image will have same size as the original image would have when displayed at 96dpi.
