Example
MyImage is Image = "Test.gif"
// Draw a circle section whose
// background is light yellow and whose border is light blue
MyImage.DrawSlice(10, 10, 50, 50, 20, 20, 40, 50, LightYellow, LightBlue)
IMG_MyDrawing = MyImage
 
Syntax
<Image variable>.DrawSlice(<X1> , <Y1> , <X2> , <Y2> , <X3> , <Y3> , <X4> , <Y4> [, <Background color> [, <Line color>]])
<Image variable>: Image variable
Name of Image variable to use.
<X1>: Integer
X coordinate of top left corner of the rectangle containing the circle. These coordinates are expressed in pixels.
<Y1>: Integer
Y coordinate of top left corner of the rectangle containing the circle. These coordinates are expressed in pixels.
<X2>: Integer
X coordinate of bottom right corner of the rectangle containing the circle. These coordinates are expressed in pixels.
<Y2>: Integer
Y coordinate of bottom right corner of the rectangle containing the circle. These coordinates are expressed in pixels.
<X3>: Integer
X coordinate of start point of the circle section. These coordinates are expressed in pixels.
<Y3>: Integer
Y coordinate of start point of the circle section. These coordinates are expressed in pixels.
<X4>: Integer
X coordinate of end point of the circle section. These coordinates are expressed in pixels.
<Y4>: Integer
Y coordinate of end point of the circle section. These coordinates are expressed in pixels.
<Background color>: Integer or constant (optional)
Background color of circle section. This color can correspond to:
If this parameter is not specified, the background color:
<Line color>: Integer or constant (optional)
Color of the line for the circle section. This color can correspond to:
If this parameter is not specified, the line color:
Remarks

Coordinates

If the start point and the end point 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).
Coordinates are given with respect to the top left corner of the image (coordinates: (0.0)).
The drawing sections are drawn anticlockwise.

Non-solid figure

To draw a non-solid figure (without taking into account the center of the circle), use <Image variable>.DrawChord.

Drawing with opacity or anti-aliasing

For a drawing with opacity (<Image variable>.StartDrawing with the dWithOpacity constant) or anti-aliasing (<Image variable>.ChangeMode with the drawAntiAliasing constant), the outline is drawn over the inside of the section: therefore, the line is partly combined with the inside of the section. If the line is very thick, it will be displayed in two colors.
