Example
// Declare the promotion image
MyPromoImage is Image = "PromoImage.png"

// Blend the promotion image in the product image with an opacity set to 80%
dAlphaBlend(IMG_PRODUCT, MyPromoImage, 80)
Syntax
dAlphaBlend(<Destination Image> , <Source Image> [, <Opacity>])
<Destination Image>: Image variable or Image control
Image in which the merge must be performed. This image can correspond:
  • the name of an Image control.
  • the name of an Image variable.
During the merge, this image will be considered as being the background image.
<Source Image>: Image variable or Image control
Image that must be merged with the Destination Image>. This image can correspond:
  • the name of an Image control.
  • the name of an Image variable.
<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.
  • dAlphaBlend performs the merge by keeping the alpha layer of the destination image. Therefore, the alpha layer of the source image is not used.
