i'd like to have different images in a project and change their alpha property dynamically using scripts.
since i can't find the color category of an image in the viewer i don't know how to access its alpha property.
thanks for your time!
Hmm. Etoys taught me how to use squeak. Basicly the Etoys "safe" environment taught me that it was easier to get things done if I focused on using the more dangerous but less restrictive environment it was written in.
Karl is right about the restrictions of the tiling system. While I found some easy ways to modify a picture that comes from a .gif file. I couldn't find a good way to do it in the tile scripting system.
Its a good ability to want. So I think you raised a good question. You've just thought of something other's haven't addressed. I intend to play with is some more. If I come up with something I will let you know.
Here is a good starting point. http://wiki.squeak.org/squeak/2411 I'm not sure if a alpha filter is implemented in this package.
I think this would be a nice addition to the Etoys image as well, with some needed integration with Etoys.

Yours in curiosity and service, --Jerome Peace

The short answer is yes.
The long answer depends on what you want to do.
