<Image variable>.DrawPolygon (Function) In french: <Variable Image>.DessinePolygone
MyImage is Image = "Test.gif" // Draw a 4-side polygon whose // background is light yellow and whose border is light blue MyImage.DrawPolygon(4, 10, 20, 20, 50, 40, 60, 50, 10, LightYellow, LightBlue) IMG_MyDrawing = MyImage
Syntax
Building a polygon point by point Hide the details
<Image variable>.DrawPolygon(<Number of sides> , <X1> , <Y1> , <X2> , <Y2> [, <X3> , <Y3> [... [, <Xn> , <Yn>]]] [, <Background color> [, <Side color>]])
<Image variable>: Image variable Name of the Image variable to use. <Number of sides>: Integer Number of sides in the polygon (up to 23 sides). This parameter defines the number of <X>, <Y> pairs to specify in the function. <X1>: Integer X coordinate of first point of the polygon. These coordinates are expressed in pixels. <Y1>: Integer Y coordinate of first point of the polygon. These coordinates are expressed in pixels. <X2>: Integer X coordinate of second point of the polygon. These coordinates are expressed in pixels. <Y2>: Integer Y coordinate of second point of the polygon. These coordinates are expressed in pixels. <X3>: Integer X coordinate of 3rd point of the polygon. These coordinates are expressed in pixels. <Y3>: Integer Y coordinate of 3rd point of the polygon. These coordinates are expressed in pixels. <Xn>: Optional integer X coordinate of nth point of the polygon. These coordinates are expressed in pixels. <Yn>: Optional integer Y coordinate of nth point of the polygon. These coordinates are expressed in pixels. <Background color>: Integer or constant (optional) Background color of polygon. This color can correspond to:If this parameter is not specified, the background color: <Side color>: Integer or constant (optional) Color of polygon sides. This color can correspond to:If this parameter is not specified, the line color:

Remarks Coordinates Drawing a polygon:
MyImage.DrawPolygon(5, 80, 10, 10, 150, 100, 200, 160, 80, 140, 40)
Coordinates are given with respect to the top left corner of the image (coordinates: (0.0)). Important: There is no need to close the polygon (the coordinates of last point do not have to be equal to the coordinates of first point). The polygon is automatically "closed". Limits: a polygon can contain up to 100 000 points in WINDEV, WEBDEV and Java, and up to 1000 points in Windows CE.
