Syntax
dAlphaBlend(<Destination image> , <Source image> [, <Opacity>])
<Destination image>: Image control or Image, WDPic or picLayer variable

<Source image>: Image control or Image, WDPic or picLayer variable
Image to merge. This image can correspond to:
  • the name of an Image control.
  • the name of a variable of type Image.
  • WEBDEV - Server code the name of a variable of type WDPic. Only the background layer will be handled.
  • WEBDEV - Server code the name of a variable of type picLayer.
<Opacity>: Optional real
Percentage of opacity that must be applied to <Source image> before performing the blend (100% by default, no opacity is applied).
