drawFilledCircle - Circles

This function allows you to draw filled circles. It is possible to tune the rendering by playing with the $Format array. To learn more about this please read the Format array guide. This functions are supporting anti-alias and shadows.

Calling this function
Where :

X1,Y1 are the center coordinate of the circle.
Radius is the radius of the circle.
Format is an array containing the drawing parameters.

Customisation array - Tune up your circle!

It is possible to customize the circle rendering by playing with this array. Providing a detailled configuration is not mandatory, by default the circles will be drawn black with no transparency.

The fill color can be set with R, G, B.
The border color can be set with BorderR, BorderG, BorderB.
The border alpha factor can be set with BorderAlpha.
You can use the Surrounding option to define the border color. This value will be added to the R,G,B factors to define the border color.
The alpha transparency factor can be set with Alpha.
You can draw dashed border lines using the Ticks parameter.

Sample script

 /* Left circles with different alpha transparency */

 /* Active shadow support */

 /* Right circles */
 $CircleSettings = array("R"=>209,"G"=>31,"B"=>27,"Alpha"=>100,"Surrounding"=>30);

 $CircleSettings = array("R"=>209,"G"=>125,"B"=>27,"Alpha"=>100,"Surrounding"=>30);

 $CircleSettings = array("R"=>209,"G"=>198,"B"=>27,"Alpha"=>100,"Surrounding"=>30,"Ticks"=>4);

 $CircleSettings = array("R"=>134,"G"=>209,"B"=>27,"Alpha"=>100,"Surrounding"=>30,"Ticks"=>4);

This will draw some transparency test on the left side of the picture and 4 colored boxes on the right. Shadow support is enabled on a (+1,+1) basis.
