- Changing the color of an area
Changing the color of an area The following code changes the color of an area in an Image control (IMG_ImageDrawing). The user clicks the Image control to select the area. The new color is selected by the user via a radio button (RADIO_SelectColor). The coordinates of the mouse click can be retrieved with MouseXPos and MouseYPos. In this example, we will assume that the Image control (IMG_ImageDrawing) contains several drawings. // -- Click code of "IMG_ImageDrawing"
// Declare the variables
AreaColor is int
XCoord is int
YCoord is int
Â
// Declare the drawing in the "IMG_ImageDrawing" control
dStartDrawing(IMG_ImageDrawing)
Â
// Retrieve the coordinates of the mouse click
XCoord = MouseXPos()
YCoord = MouseYPos()
Â
// Retrieve the selected fill color
SWITCH RADIO_SelectColor
CASE 1: AreaColor = LightRed
CASE 2: AreaColor = LightBlue
CASE 3: AreaColor = LightGreen
CASE 4: AreaColor = LightYellow
END
Â
// Color the area
dFill(XCoord, YCoord, AreaColor)
