Implements a drawing surface for GcBitmap.
public class GcBitmapGraphics : GcGraphics, IDisposableGets the source GcBitmap.
public GcBitmap Bitmap { get; }Gets the height of the image, in DIPs.
public float Height { get; }Gets the BitmapRenderer that is used to draw on the GcBitmap.
public BitmapRenderer Renderer { get; }Gets the resolution of the current graphics (always 96 DPI for GcBitmapGraphics).
public override float Resolution { get; set; }Gets the resolution of the underlying drawing surface (pixels per inch).
public override float? SurfaceResolution { get; }Gets or sets the transformation matrix of the current graphics.
public override Matrix3x2 Transform { get; set; }Gets the width of the image, in DIPs.
public float Width { get; }For internal use.

protected override void InternalSetClip(IClipRegion clipRegion)clipRegion IClipRegionIndicates whether this graphics implementation supports a specified blend mode.
GcBitmapGraphics supports all blend modes, so this method always returns true.
public override bool IsBlendModeSupported(BlendMode blendMode)blendMode BlendModeThe blend mode to check.
Indicates whether this graphics implementation supports a specified interpolation mode.
GcBitmapGraphics supports all interpolation modes, so this method always returns true.
public override bool IsInterpolationModeSupported(InterpolationMode interpolationMode)interpolationMode InterpolationModeThe interpolation mode to check.
true if the specified interpolation mode is supported by GcBitmapGraphics, false otherwise.
Stops redirecting drawing operations to the transparency layer that was created by the last PushTransparencyLayer(RectangleF?, float) call.
public override void PopTransparencyLayer()Adds a transparency layer to the GcBitmapGraphics so that it receives all subsequent drawing operations until PopTransparencyLayer() is called.
public override void PushTransparencyLayer(RectangleF? contentBounds, float opacity)contentBounds RectangleF?The content bounds of the transparency layer. Content won't render outside these bounds. When set to null, the content bounds are effectively taken to be the bounds of the current GcBitmapGraphics.
opacity floatAn opacity value that is applied uniformly to all drawings in the layer when compositing to the backplate.
