Canvas functions work on the current canvas, the last one made with $canvasCreate; they have no canvas-name argument. Called before any $canvasCreate they have no effect. Numeric arguments must be whole numbers; text that is not a whole number gives the default of that parameter.

Parameters

Parameter	Description
x, y	Required. Center of the circle.
radius	Required. Radius in pixels (default 10 if not a whole number).
color	Required. Colors are a 6-digit hexadecimal value with or without # (#5865F2), an 8-digit RRGGBBAA value, or one of these names (case-insensitive): red, green, blue, white, black, transparent, yellow, cyan, magenta, orange, purple, pink, gray, grey, lime, navy, teal, aqua, maroon, silver, gold. An empty or unreadable color becomes white. The 3-digit shorthand #abc is not supported (it is read as 000ABC).
fill	Required. true, yes or 1 fill the shape; false, no or 0 draw only a 1-pixel outline. Any other value fills it.
blend	Optional. Blend modes (case-insensitive): multiply, screen, overlay, darken, lighten, difference, hardlight, softlight. normal, srcover or an empty value use the plain drawing; any other text (for example source-over) is handled as a normal alpha blend.
container	Optional. Name of a container defined earlier with $canvasContainer: the x/y position is then offset by the container’s x/y. An unknown name means no offset.

Behavior

• With a blend mode the pixels are blended one by one instead of simply painted.
• Parts of the circle outside the canvas are cut off.
