Image Compositions
In this example we compose a new image / texture out of one image and some 2d effects.
Basic Setup
Image compose
creates a new texture, the children ops ofImage Compose
apply 2D effects onto the textureDrawImage
applies an image- This example does not change the image at all, it is just a basic setup
Apply An Effect
- To blur the image we add
Blur
to the end of the image composition chain - The image is now blurred, you can change the
Blur
parameters, or animate them
Add an Alpha Mask
DrawImage
has a a slot calledimageAlpha
- Create a new
texture
op and connect it to theimageAlpha
port of thedrawImage
op. - Select it and now click
file
in the main panel. Browse through the library until you find an image like this.
- Using the
AlphaSrc
setting in thedrawImage
op you can select what defines the alpha / opacity value, in this case it's luminance of our alpha image. - If nothing happens try changing the
AlphaSrc
setting toalpha channel
.
