<picLayer variable>.DrawArc (Function) In french: <Variable picCalque>.DessineArc Draws a circle arc or an ellipse arc in a variable of type picLayer. The arc is drawn counterclockwise.
MyImage is WDPic = "Test.gif" MyLayer is picLayer // Draw a light yellow arc of circle on the layer MyLayer.DrawArc(10, 10, 50, 50, 20, 20, 40, 50, LightYellow) IMG_MyDrawing = MyImage
Syntax
Drawing an arc Hide the details
<picLayer image>.DrawArc(<X1> , <Y1> , <X2> , <Y2> , <X3> , <Y3> , <X4> , <Y4> [, <Line color> [, <Line thickness>]])
<picLayer image>: picLayer variable Name of the picLayer variable to be used. <X1>: Integer X-coordinate (in pixels) of the upper-left corner of the rectangle containing the circle. <Y1>: Integer Y-coordinate (in pixels) of the upper-left corner of the rectangle containing the circle. <X2>: Integer X-coordinate (in pixels) of the lower-right corner of the rectangle containing the circle. <Y2>: Integer Y-coordinate (in pixels) of the lower-right corner of the rectangle containing the circle. <X3>: Integer X-coordinate (in pixels) of the starting point of the arc. <Y3>: Integer Y-coordinate (in pixels) of the starting point of the arc. <X4>: Integer X-coordinate (in pixels) of the end point of the arc. <Y4>: Integer Y-coordinate (in pixels) of the end point of the arc. <Line color>: Integer or constant (optional) Color of the arc of circle. This color can correspond to:If this parameter is not specified, the line color:- is Transparent if <Image>.Pen has not been used beforehand,
- corresponds to the color specified in the last call to <Image>.Pen.
<Line thickness>: Optional integer Remarks Coordinates of the arc If the start and end points are not located on the border of the circle (or on the border of the ellipse), the point taken into account corresponds to the intersection between the circle and the line that joins the specified point and the center of the rectangle (which means the center of the circle).
The origin used to calculate the coordinates corresponds to the upper-left corner of the image (coordinates: (0,0)).
