Syntax

<Image variable>.DrawCircle(<X1> , <Y1> , <X2> , <Y2> [, <Background color> [, <Line color>]])

<Image variable>: Image variable

Name of the Image variable to be used.

<X1>: Integer

X-coordinate of the upper-left corner of the rectangle containing the circle. These coordinates are expressed in pixels.

<Y1>: Integer

Y-coordinate of the upper-left corner of the rectangle containing the circle. These coordinates are expressed in pixels.

<X2>: Integer

X-coordinate of the lower-right corner of the rectangle containing the circle. These coordinates are expressed in pixels.

<Y2>: Integer

Y-coordinate of the lower-right corner of the rectangle containing the circle. These coordinates are expressed in pixels.

<Background color>: Integer or constant (optional)

Circle background color. This color can correspond to:
an RGB color (returned by RGB),
an HSL color (returned by HSL),
a WLanguage preset color,
a variable of type Color.
If this parameter is not specified, the background color:
is Transparent if <Image variable>.Background has not been used beforehand,
corresponds to the color specified in the last call to <Image variable>.Background.

<Line color>: Integer or constant (optional)

Color of the circle line. This color can correspond to:
an RGB color (returned by RGB),
an HSL color (returned by HSL),
a WLanguage preset color,
a variable of type Color.
If this parameter is specified, the characteristics indicated by the <Image variable>.Pen function are ignored.. The thickness of the Line is therefore 1.
If this parameter is not specified, the line color:
corresponds to the color specified in the last call to <Image variable>.Pen,
is the same as the background color if <Image variable>.Pen has not been used.

Remarks

Coordinates

Coordinates are specified with respect to the upper-left corner of the Image control (coordinates: (0,0)).
