Hi all,
I would like to create some kind of artistic project on Pharo/Squeak. The idea is to make some images appear and vanish slowly after a while. Browsing the net I have found this code on pharo to change the background:
|form| form := (Form fromBinaryStream: (HTTPSocket httpGet: 'http://ubuntu.ecchi.ca/wallpapers/10.04/' , 'Maraetaibeforesunrise.jpg')). World backgroundImage: form layout: #scaled
and I imagine that something similar is needed to load any image from Internet or hard disk changing the path and making it appear on the screen. I have tried this:
x := ImageMorph new. x image: (Form fromFileNamed: '/home/offray/Temp/myFile.png'). x openInWorld.
and is working, but I can get the halos on this image on pharo using Ctrl + Shif + Click on Pharo, but is not working. So I have 3 questions:
1. There is any way to get halos on the image by coding instead of clicking on it?
2. Can I use alpha channels to make the loaded image fade after a while once it appeared?
3. I'm using Pharo one click image. There is any way to use the local paths of the image to load some images and load some others from the Internet? The idea is to distribute the small artistic project in this way.
This is trying to be a weekend newbie project, to show to my interactive art teacher, so any quick help would be really appreciated (first I was trying to get the idea, and the using Etoys, so now I'm on pharo, hoping to make this work easily).
Thanks,
Offray
Hi,
Some post about my advances.

This is not needed. Now I can use Shift + Ctrl + Middle Click to get the proper halos without any problem. Now I want to scale the image from code. I will keep you posted.
This two are still open questions.
- Can I use alpha channels to make the loaded image fade after a while
once it appeared?
- I'm using Pharo one click image. There is any way to use the local
paths of the image to load some images and load some others from the Internet? The idea is to distribute the small artistic project in this way.

So one way to make a loaded image "fade" us to place a playfield over the image (with alpha = 0), then have a script that increases the alpha to 100 over a period of time. The playfield should be the same color as your background.
Also it would be great if you could share the code that loads the image and make it appear on the screen.

Steve, Great idea to use the playfield that way, thanks for sharing! Kathleen

Sounds good. I have decided to create a "biography of a incomplete project" as my "interactive art" project talking about how it started with "physical etoys", went to "Etoys" then Pharo, but still is not finished (in Spanish) I will be sharing the link with you.
The code to load a file is this:
x := ImageMorph new. x image: (Form fromFileNamed: '/home/offray/Temp/myFile.png'). x openInWorld.

Hi Offray,
Regarding fading images I think you'll find this useful: http://coweb.cc.gatech.edu/cs2340/4278.
The example there works fine in Squeak but I couldn't make it work in Etoys yet. It's possibly a BitBlt bug but I haven't checked further.
Cheers, Richo

Thanks a lot. It seems realy close to what I was looking for. Yerterday the dead line for submissions of our interactive art project were closed, so I decided to send a "Digital Distopia: a biography of an unfinished project" as my project. Is in Spanish, so you can check it here:
The future explorations posted in the article are now the way to go :-).
Thanks,
