hi jerome,

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.
  

Yours in curiosity and service, --Jerome Peace

hiya all!

is it possible to alter the alpha value of an
        

imported
    

image [jpg, png, etc]?

        

The short answer is yes.

The long answer depends on what you want to do.

Alter how?
