IndigoCanvasRenderingContext2D

Adds an arc to the path which is centered at (x, y) position with radius r starting at startAngle and ending at endAngle going in the given direction by anticlockwise (defaulting to clockwise).

Adds an arc with the given control points and radius, connected to the previous point by a straight line.

Starts a new path by resetting the list of sub-paths. Call this method when you want to create a new path.

Sets all pixels in the rectangle defined by starting point (x, y) and size (width, height) to transparent black.

Creates a clipping path from the current sub-paths. Everything drawn after clip() is called appears inside the clipping path only. For an example, see Clipping paths in the Canvas tutorial.

Tries to draw a straight line from the current point to the start. If the shape has already been closed or has only one point, this function does nothing.

Creates a new, blank ImageData object with the specified dimensions. All of the pixels in the new object are transparent black.

Draws the specified image. This method is available in multiple formats, providing a great deal of flexibility in its use.

The ellipse() method creates an elliptical arc centered at (x, y) with the radii radiusX and radiusY. The path starts at startAngle and ends at endAngle, and travels in the direction given by anticlockwise (defaulting to clockwise).

Fills the subpaths with the current fill style.

Draws a filled rectangle at (x, y) position whose size is determined by width and height.

Returns an ImageData object representing the underlying pixel data for the area of the canvas denoted by the rectangle which starts at (sx, sy) and has an sw width and sh height.

Returns a dash list array containing an even number of non-negative numbers.

Reports whether or not the specified point is contained in the current path.

Connects the last point in the subpath to the x, y coordinates with a straight line.

Moves the starting point of a new subpath to the (x, y) coordinates.

Restores the drawing style state to the last element on the 'state stack' saved by save().

Saves the current drawing style state using a stack so you can revert any change you make to it using restore().

Strokes the subpaths with the current stroke style.

Paints a rectangle which has a starting point at (x, y) and has a w width and an h height onto the canvas, using the current stroke style.

Moves the origin point of the context to (x, y).

Text direction, left to right, right to left

"ltr" || "rtl" || "inherit"

Back-reference to the canvas element for which this context was created. Read only.

A CSS color, a CanvasGradient or CanvasPattern, to use as a fill.

Default value 10px sans-serif

Alpha value that is applied to shapes and images before they are composited onto the canvas. Default 1.0 (opaque).

With globalAlpha applied this sets how shapes and images are drawn onto the existing bitmap. Possible values: source-atop source-in source-out source-over (default) destination-atop destination-in destination-out destination-over lighter darker copy xor

A boolean value indicating whether to smooth scaled images or not. The default value is true.

Type of endings on the end of lines. Possible values: butt (default), round, square

Specifies where to start a dasharray on a line.

Defines the type of corners where two lines meet. Possible values: round, bevel, miter (default)

Width of lines. Default 1.0

Default 10

Specifies the blurring effect. Default 0

Color of the shadow. Default fully-transparent black.

Horizontal distance the shadow will be offset. Default 0.

Vertical distance the shadow will be offset. Default 0.

A CSS color, a CanvasGradient or CanvasPattern, to use as a line around shapes.

Possible values: start (default), end, left, right or center.

Possible values: top, hanging, middle, alphabetic (default), ideographic, bottom
