Inherited static methods

Arc	Adds a circular arc of the given Radius to the current path. The arc is centered at (XC, YC), begins at Angle and proceeds counter-clockwise during Length radians.
Begin	Starts painting on the specified device.
Clip	Establishes a new clip region by intersecting the current clip region with the current path as it would be filled by Paint.Fill and according to the current fill rule (see Paint.FillRule).
ClosePath	Adds a line segment to the path from the current point to the beginning of the current sub-path, (the most recent point passed to Paint.MoveTo), and closes this sub-path. After this call the current point will be at the joined endpoint of the sub-path.
Color	Creates a new brush corresponding to an opaque or translucent color.
CurveTo	Adds a cubic Bézier spline to the path from the current point to position (X3, Y3) in user-space coordinates, using (X1, Y1) and (X2, Y2) as the control points. After this call the current point will be (X3, Y3).
DrawImage	Draw an image, or part of it.
DrawPicture	Draw a Picture, or part of it.
DrawRichText	Draws a piece of rich text.
DrawText	Draws the specified text.
Ellipse	Adds an elliptic arc to the current path. The ellipse is defined by its (X, Y, Width, Height) bounding-box, begins at Angle and proceeds counter-clockwise during Length radians.
End	Ends a painting.
Fill	A drawing operator that fills the current path according to the current fill rule, (each sub-path is implicitly closed before being filled).
FillRect	Fill a rectangle with a specific color.
Image	Creates a new brush from an image.
LineTo	Adds a line to the path from the current point to position (X, Y) in user-space coordinates. After this call the current point will be (X, Y).
LinearGradient	Creates a new linear gradient brush along the line defined by (X0, Y0) and (X1, Y1), and using color stops defined by the Colors and Positions arguments.
MoveTo	Begin a new sub-path. After this call the current point will be (X, Y).
NewPath	Clears the current path. After this call there will be no path and no current point.
PathContains	Tests whether the given point is inside the area described by the current path. Device dimensions and clipping are not taken into account.
Polygon	Add a closed sub-path polygon to the current path.
RadialGradient	Creates a new radial gradient paint brush that interpolates colors between a focal point ( FX , FY ) and end points on a circle defined by ( CX0 , CY0 , Radius0 ), and using color stops defined by the Colors and Positions arguments.
Rectangle	Adds a closed sub-path rectangle of the given size to the current path at position (X, Y) in user-space coordinates.
RelCurveTo	Relative-coordinate version of CurveTo.
RelLineTo	Relative-coordinate version of LineTo.
RelMoveTo	Begin a new sub-path. After this call the current point will be offset by (X, Y).
Reset	Resets the transformation matrix to the identity.
ResetClip	Reset the current clip region to its original, unrestricted state. That is, set the clip region to an infinitely large shape containing the target surface. Equivalently, if infinity is too hard to grasp, one can imagine the clip region being reset to the exact bounds of the target surface.
Restore	Restores the drawing state to the state saved by a preceding call to Save and removes that state from the stack of saved states.
RichText	Adds the specified rich text to the current path, using the current font defined by the Font property.
RichTextExtents	Gets the extents for a string of rich text.
RichTextSize	Return the bounding box needed by a string of rich text.
Rotate	Modifies the current transformation matrix (CTM) by rotating the user-space axes by angle radians. The rotation of the axes takes places after any existing transformation of user space. The rotation direction for positive angles is from the positive X axis toward the positive Y axis.
Save	Makes a copy of the current drawing state and saves it on an internal stack of saved states.
Scale	Modifies the current transformation matrix (CTM) by scaling the X and Y user-space axes by sx and sy respectively. The scaling of the axes takes place after any existing transformation of user space.
Stroke	A drawing operator that strokes the current path according to the current line width, line join, line cap, and dash settings.
Text	Adds the specified text to the current path, using the current font defined by the Font property.
TextExtents	Gets the extents for a string of text.
TextSize	Return the bounding box needed by a string of text.
Translate	Modifies the current transformation matrix (CTM) by translating the user-space origin by (TX, TY).
ZoomImage	Draw a quick zoomed version of an image or a part of it.
