<WDPic variable>.DrawArc (Function) In french: <Variable WDPic>.DessineArc Draws a circle arc or an ellipse arc in a variable of type WDPic. The arc is drawn counterclockwise.
MonWDPic is WDPic = "Test.gif"
MonWDPic.DessineArc(10, 10, 50, 50, 20, 20, 40, 50, LightYellow)
IMG_MonDessin = MonImage
Syntax
Draw an arc specifying all the coordinates of the rectangle containing the arcDraw an arc specifying all the coordinates of the rectangle containing the arc Hide the details
<WDPic image>.DrawArc(<X1> , <Y1> , <X2> , <Y2> , <X3> , <Y3> , <X4> , <Y4> [, <Line color> [, <Line thickness>]])
<WDPic image>: WDPic variable Name of the WDPic variable to be used. Only the background layer will be handled. <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 the function <WDPic variable>.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 <WDPic variable>.Pen.
<Line thickness>: Optional integer New in version 2024

<WDPic image>: WDPic variable Name of the WDPic variable to be used. Only the background layer will be handled. <Rectangle>: Rectangle variable Name of the Variable type Rectangle Receiver in which the circle is inscribed.. <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 <WDPic variable>.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 <WDPic variable>.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)).
