Blending two images

[Ikerkaz]

Hi to all

I would like to blend two identical images. I am doing a space game, and I want to show some kind of warp flash in the ship engines

I have a flash sprite (PNG with transparency), and I want to paint two of them, one very close to the other.

But the image blending is not showing the way I like...

This is what QB64 does:


I would like to paint something like this (I made the example in photoshop):


Is there any way to paint this images as the second example?

Thank yoy very much
