Functions
Arc
arc(x, y, w, h, start, extent, type, border_color, fill_color)Draws an arc.
Parameters
- x: the x coordinate of the upper-left corner of the arc's framing rectangle
- y: the y coordinate of the upper-left corner of the arc's framing rectangle
- w: the overall width of the full ellipse of which this arc is a partial section
- h: the overall height of the full ellipse of which this arc is a partial section
- start: the starting angle of the arc in degrees
- extent: the angular extent of the arc in degrees
- type: the closure type for the arc: "open", "chord" or "pie"
- border_color: fill color can be set using an RGB comma separated numeric notation, with primary color numbers from 0 to 255 (for example, “color:255,0,0” is red), or using color names. The valid names are: black, blue, cyan, darkgray, gray, lightgray, green, magenta, orange, pink, red, white, yellow.
- fill_color: fill color can be set using an RGB comma separated numeric notation, with primary color numbers from 0 to 255 (for example, “color:255,0,0” is red), or using color names. The valid names are: black, blue, cyan, darkgray, gray, lightgray, green, magenta, orange, pink, red, white, yellow.
