Example
MyWDPicImage is WDPic = "Test.gif"
MyLayer is picLayer
 
// Identify the color of the pixel (15, 25)
// on MyLayer
ResColor = MyLayer.PixelColor(15, 25)
IMG_MyDrawing = MyWDPicImage
Syntax
<Result> = dPixelColor([<Image>, ] <X coordinate> , <Y coordinate>)
<Result>: Integer
Color of the specified pixel in RGB format.
Caution: the value returned may differ according to the display configuration (resolution, ...).
<Image>: picLayer variable
Name of the picLayer variable to use.
<X coordinate>: Integer
Horizontal position of pixel to use.
<Y coordinate>: Integer
Vertical position of pixel to use.
Remarks

Coordinates

Coordinates are given in pixels with respect to the top left corner of the image (coordinates: (0.0)).

How to retrieve the components of the color?

To retrieve the components of the color returned by <picLayer variable>.PixelColor:
  • To get the red component, use RGBRed (or perform a division modulo 256 of <Result>),
  • To get the green component, use RGBGreen (or perform a division modulo 256 of <Result>/256),
  • To get the blue component, use RGBBlue (or perform a division modulo 256 of <Result>/256/256).
