Hi,

I'm just starting with ImageEn and I'd like to test it for some overlays in Delphi.

I'd like to have an ImageEnView with a loaded image, but I'd like to have another ImageEnView on the top, with a .png file on it. This new png will work as a layer and I'd need the second ImageEnView has a transparent background. That way I can see the first imageEnView

I'm trying to do it, but I'm pretty new to ImageEn

thanks so much

I

A TImageEnView is not a transparent control, so if you stack them you won't be able to see the underlying one.

It sounds like you need to use layers, i.e. a background image layer, and a transparent layer on top.

e.g.

// Load background image
ImageEnView1.IO.LoadFromFile( 'C:\Background.jpg' );

// Add an image layer
ImageEnView1.LayersAdd( ielkImage );

// Load image into the current layer
ImageEnView1.IO.LoadFromFile( 'C:\Transparent.png' );

Please also try the demos under:
