MyWDPicImage is WDPic = "Test.gif" // Identify the opacity of the pixel (15, 25) // on MyWDPicImage ResOpacity = MyWDPicImage.PixelOpacity(15, 25) IMG_MyDrawing = MyWDPicImage
Syntax
<Result> = <WDPic image>.PixelOpacity(<X-coordinate> , <Y-coordinate>)
<Result>: Integer Opacity of specified pixel (included between 0 for transparent and 255 for opaque). <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.
