Transparent Sprites

What is it you are trying to achieve?
Produce transparent sprites in Turing


What is the problem you are having?

My group is making a Turn based Strategy Game and we are having trouble putting a sprite with a transparent background on a window that is a .jpg image. The sprite is placed on the background but the background of that image is not transparent and the background of the sprite is shown instead of the map.


Describe what you have tried to solve this problem
We tried using the different modes for Pic.Draw but i think i am missing something


Please specify what version of Turing you are using
4.1.1 and 4.0.5 (yes, weird)

First off you shouldn't be using jpg's for that. The reason being is that jpeg compression can cause colours to "bleed" into eachother. I'm pretty sure turing supports raw .bmp's the best.

To blend images into a background use picMerge instead of picCopy

Also that jpegs don't have an alpha (transparency) channel
