Blends two images together. This allows you to create fade-in effects between 2 images.
Example
MyWDPicImage is WDPic = "Test.gif"
MyLayer is picLayer
// Declare the promotion image
MyPromoImage is Image = "PromoImage.png"
// Blend the promotion image in the product image with an opacity set to 80%
MyLayer.AlphaBlend(MyPromoImage, 80)
IMG_MyDrawing = MyWDPicImage
Syntax
<Destination image>.Blend(<Source image> [, <Opacity>])
<Destination image>: picLayer variable
Name of the picLayer variable in which the blend must be performed. For the blend, this image will be considered as the background image.
<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 an Image variable.
  • Versions 25 and later
    WINDEVWEBDEV - Server code the name of a WDPic variable. Only the background layer will be handled.
    New in version 25

<Opacity>: Optional real
Percentage of opacity that must be applied to <Source image> before performing the blend (100% by default, no opacity is applied).
Remarks
  • The size of the destination image corresponds to the reference size.
  • <picLayer variable>.AlphaBlend performs the merge by keeping the alpha layer of the destination image. Therefore, the alpha layer of the source image is not used.
