DpiHelper.DpiHelperImplementation Class
The DpiHelper actual implementation. Derives from the DpiHelper scaling helper, and overrides a couple of functions allowing user-override of the scaling algorithms via registry settings under the running appid's hive.

![]() | DpiHelper.DpiHelperImplementation() | Initializes a new instance of DpiHelperImplementation. |
| Name | Description | |
|---|---|---|
![]() | BitmapScalingMode | The BitmapScalingMode.(Inherited from DpiHelper.) |
![]() | DeviceDpiX | Gets the screen's (device) current horizontal DPI.(Inherited from DpiHelper.) |
![]() | DeviceDpiY | The screen's (device) current vertical DPI.(Inherited from DpiHelper.) |
![]() | DeviceToLogicalUnitsScalingFactorX | Converts to the horizontal logical units scaling factor.(Inherited from DpiHelper.) |
![]() | DeviceToLogicalUnitsScalingFactorY | Converts to the vertical logical units scaling factor.(Inherited from DpiHelper.) |
![]() | DpiScalePercentX | (Inherited from DpiHelper.) |
![]() | DpiScalePercentY | (Inherited from DpiHelper.) |
![]() | 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.(Inherited from DpiHelper.) |
![]() | IsScalingRequired | Determines whether scaling is required when converting between logical-device units(Inherited from DpiHelper.) |
![]() | LogicalDpiX | Gets the helper's logical horizontal DPI.(Inherited from DpiHelper.) |
![]() | LogicalDpiY | Gets the helper's vertical horizontal DPI.(Inherited from DpiHelper.) |
![]() | LogicalToDeviceUnitsScalingFactorX | (Inherited from DpiHelper.) |
![]() | LogicalToDeviceUnitsScalingFactorY | (Inherited from DpiHelper.) |
![]() | PreScaledImageLayoutTransformScaleX | Gets the horizontal scale value that should be used with a LayoutTransform/ScaleTransform to scale back an image pre-scaled in HighDPI with DpiPrescaleImageSourceConverter in order to obtain crisp results.(Inherited from DpiHelper.) |
![]() | PreScaledImageLayoutTransformScaleY | Gets the vertical scale value that should be used with a LayoutTransform/ScaleTransform to scale back an image pre-scaled in HighDPI with DpiPrescaleImageSourceConverter in order to obtain crisp results.(Inherited from DpiHelper.) |
![]() | SettingsStore | |

![]() | TransformToDevice | (Inherited from DpiHelper.) |
![]() | UsePreScaledImages | Determines whether images should be pre-scaled at zoom levels higher than 200%, using NearestNeighbor up to the largest multiple of 100%(Inherited from DpiHelper.) |
| Name | Description | |

![]() | CreateDeviceFromLogicalImage(Bitmap, Size, Color, ImageScalingMode) | Creates and returns a new bitmap strip from the logical Bitmap scaled for the device units. When displayed on the device, the scaled image strip will have same size as the original image strip would have when displayed at 96dpi. This should be used for converting imagelists bitmap strips instead of simply scaling the bitmap, because the resultant bitmap strip size may be different from just upscaling as bitmap N * Math.Round(width * dpiscale) != Math.Round(N * width * dpiscale). This may happen depending on the image width because dpiscale is a double not an int.(Inherited from DpiHelper.) |
![]() | CreateDeviceFromLogicalImage(Bitmap, Size, ImageScalingMode) | Creates and returns a new bitmap strip from the logical Bitmap scaled for the device units. When displayed on the device, the scaled image strip will have same size as the original image strip would have when displayed at 96dpi. This should be used for converting imagelists bitmap strips instead of simply scaling the bitmap, because the resultant bitmap strip size may be different from just upscaling as bitmap N * Math.Round(width * dpiscale) != Math.Round(N * width * dpiscale). This may happen depending on the image width because dpiscale is a double not an int.(Inherited from DpiHelper.) |
![]() | CreateDeviceFromLogicalImage(Icon, ImageScalingMode) | Creates and returns a new icon scaled for the device units. When displayed on the device, the scaled icon will have same size as the original icon would have when displayed at 96dpi.(Inherited from DpiHelper.) |
![]() | CreateDeviceFromLogicalImage(Image, Color, ImageScalingMode) | Creates and returns a new ImageList scaled for the device units. When displayed on the device, the scaled ImageList will have same size as the original ImageList would have when displayed at 96dpi.(Inherited from DpiHelper.) |
