Syntax
Draw an arc, specifying all the coordinates of the rectangle containing the arc Hide the details
<Image control>.DrawArc(<X1> , <Y1> , <X2> , <Y2> , <X3> , <Y3> , <X4> , <Y4> [, <Line color> [, <Line thickness>]])
<Image control>: Control name Name of the Image control to be used. <X1>: entier X-coordinate (in pixels) of the upper-left corner of the rectangle containing the circle. <Y1>: entier Y-coordinate (in pixels) of the upper-left corner of the rectangle containing the circle. <X2>: entier X-coordinate (in pixels) of the lower-right corner of the rectangle containing the circle. <Y2>: entier Y-coordinate (in pixels) of the lower-right corner of the rectangle containing the circle. <X3>: entier X-coordinate (in pixels) of the starting point of the arc. <Y3>: entier Y-coordinate (in pixels) of the starting point of the arc. <X4>: entier X-coordinate (in pixels) of the end point of the arc. <Y4>: entier 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 the function <Image>.Pen has not been used before.
New in version 2024In the case of an Variable type Image, the row will have the black Color.. - corresponds to the color specified in the last call to <Image>.Pen.
<Line thickness>: Optional integer New in version 2024 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)).
