| FillRoundRect | Fills a rectangle with rounded corners using the specified fill style. |
| GetFillColor | Returns the current fill color applied to the canvas. |
| GetMatrix | Returns the current transformation matrix applied to the canvas. |
| PathClose | Closes the current open sub-path by connecting the last point back to the first point. |
| PathLineTo | Adds a straight line segment from the current path cursor to the specified point. |
| PathMoveTo | Moves the path cursor to the specified point without drawing a line. |
| PathOpen | Opens an existing path object to prepare it for new segment additions. |
| Render | Flushes pending drawing operations and renders the current frame to the canvas. |
| ResetClip | Removes any active clipping region, restoring the full canvas drawing area. |
| ResetTextAngle | Resets a previously applied text rotation angle. |
| ResetTransform | Resets all active transformation matrices to the identity transform. |
| RestoreState | Restores a previously saved graphics state including transforms, clip, and style settings. |
| RotateTransform | Applies a rotation transformation to the current drawing context. |
| SaveState | Saves the current graphics state into the provided state object. |
| ScaleTransform | Applies a scale transformation to the current drawing context. |
| SetAntiAliasing | Enables or disables anti-aliasing for drawing operations. |
| SetFill | Applies all properties of the given fill descriptor to the canvas fill settings. |
| SetFillColor | Sets the solid fill color for subsequent fill operations. |
| SetFillKind | Sets the fill kind, such as solid, gradient, or bitmap. |
| SetFont | Applies all properties of the given font object to the canvas text settings. |
| SetFontColor | Sets the foreground color used for subsequent text rendering. |
| SetFontName | Sets the font family name for subsequent text rendering. |
| SetFontSize | Sets the font size for subsequent text rendering. |
| SetFontStyles | Sets the font style flags such as bold, italic, or underline. |
| SetMatrix | Replaces the current transformation matrix with the specified matrix. |
| SetScale | Applies a uniform scale factor to the current transformation. |
| SetShowAcceleratorChar | Controls whether keyboard accelerator characters are underlined in drawn text. |
| SetSize | Updates the logical size of the drawing surface. |
| SetStroke | Applies all properties of the given stroke descriptor to the canvas stroke settings. |
| SetStrokeColor | Sets the stroke color for subsequent outline drawing operations. |
