Constructors

DeviceContext1(Device1, DeviceContextOptions)

Initializes a new instance of the DeviceContext1 class using an existing Device1.

public DeviceContext1(Device1 device, DeviceContextOptions options)

Parameters

device Device1

The device.

options DeviceContextOptions

The options to be applied to the created device context.

Remarks

The new device context will not have a selected target bitmap. The caller must create and select a bitmap as the target surface of the context.

DeviceContext1(nint) 

public DeviceContext1(nint nativePtr)

Parameters

nativePtr nint

Methods

DrawGeometryRealization(GeometryRealization, Brush)

Renders a given geometry realization to the target with the specified brush.

public void DrawGeometryRealization(GeometryRealization geometryRealization, Brush brush)

Parameters

geometryRealization GeometryRealization

The geometry realization to be rendered.

brush Brush

The brush to render the realization with.

Remarks

This method respects all currently set state (transform, DPI, unit mode, target image, clips, layers); however, artifacts such as faceting may appear when rendering the realizations with a large effective scale (either via the transform or the DPI). Callers should create their realizations with an appropriate flattening tolerance using either D2D1_DEFAULT_FLATTENING_TOLERANCE or ComputeFlatteningTolerance to compensate for this.

Additionally, callers should be aware of the safe render bounds when creating geometry realizations. If a geometry extends outside of [-524,287, 524,287] DIPs in either the X- or the Y- direction in its original (pre-transform) coordinate space, then it may be clipped to those bounds when it is realized. This clipping will be visible even if the realization is subsequently transformed to fit within the safe render bounds.

Operators

explicit operator DeviceContext1(nint)
