Drawing a circle section in an Image control
The following code is used to draw a circle section in an Image control (IMG_ImageDrawing). The coordinates of the rectangle where the circle will be drawn and the coordinates of the start and end points of the circle section are entered by the user in edit controls (EDT_X1, EDT_Y1, EDT_X2, EDT_Y2, EDT_X3, EDT_Y3, EDT_X4, EDT_Y4). The background color and the line color of the circle section are selected by the user via two radio buttons (RADIO_SelectBackground and RADIO_SelectLine).
// Declare the variables
BackgroundColor is int
LineColor is int

// The drawing will be drawn in the "IMG_ImageDrawing" control
dStartDrawing(IMG_ImageDrawing)

// Retrieve the selected background color
SWITCH RADIO_SelectBackground
CASE 1: BackgroundColor = LightRed
CASE 2: BackgroundColor = LightBlue
CASE 3: BackgroundColor = LightGreen
CASE 4: BackgroundColor = LightYellow
END

// Retrieve the selected line color
SWITCH RADIO_SelectLine
CASE 1: LineColor = LightRed
CASE 2: LineColor = LightBlue
CASE 3: LineColor = LightGreen
CASE 4: LineColor = LightYellow
END

// Draw the circle section
dSlice(EDT_X1, EDT_Y1, EDT_X2, EDT_Y2, EDT_X3, EDT_Y3, EDT_X4, EDT_Y4, BackgroundColor, LineColor)
