Description

The SVG_New_circle command creates a new circle in the SVG container designated by parentSVGObject and returns its reference. If parentSVGObject is not an SVG document, an error is generated.

The circle is positioned and sized according to the center coordinates (x and y) and the radius passed as a parameter.

The optional foregroundColor and backgroundColor parameters contain, respectively, the name of the line color and of the background color. (For more information about colors, please refer to the commands of the Colors and Gradients theme).

The optional strokeWidth parameter contains the size of the pen expressed in pixels. Its default value is 1.

Draw a circle (default fill and border color, default line thickness):

 svgRef:=SVG_New

 objectRef:=SVG_New_circle(svgRef;100;100;90)

Example 2

Draw a light blue circle with a blue edge and a 2-point link thickness:

 svgRef:=SVG_New

 objectRef:=SVG_New_circle(svgRef;100;100;90;"blue";"lightblue";2)
