Example
MyWDPicImage is WDPic = "Test.gif"
// Identify the color of the pixel (15, 25)
// on MyWDPicImage
ResColor = MyWDPicImage.PixelColor(15, 25)
IMG_MyDrawing = MyWDPicImage
Syntax
<Result> = <WDPic image>.PixelColor(<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, ...).
<WDPic image>: WDPic variable
Name of the WDPic variable to be used. Only the background layer will be handled.
<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 upper-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 <WDPic 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).
Component: wd270obj.dll
