<Image variable>.AlphaBlend (Function)

In french: <Variable Image>.Fusionne

Blends two images together. This allows you to create fade-in effects between 2 images.

Caution: In Linux, this function requires a specific configuration. For more details, see Drawing in WINDEV, WEBDEV and WINDEV Mobile.

Example

MyImage is Image = "Test.gif"
// Declare the promotion image
MyPromoImage is Image = "PromoImage.png"
// Blend the promotion image in the product image with an opacity set to 80%
MyImage.AlphaBlend(MyPromoImage, 80)
IMG_MyDrawing = MyImage

Syntax

<Destination image>.AlphaBlend(<Source image> [, <Opacity>])

<Destination image>: Image variable

Name of the Image 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 a variable of type Image.
the name of a variable of type WDPic. Only the background layer will be handled.
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).

Remarks

The size of the destination image corresponds to the reference size.
<Image variable>.AlphaBlend blends the images and keeps the alpha channel of the destination image. Therefore, the alpha channel of the source image is not used.
