Petre S. was kind enough to forward a post by John to the K12OSN list that does a short pro/con comparison of Tux Paint to the commerical product that everyone compares Tux Paint to: Kid Pix. (Note: There seem to be numerous versions of Kid Pix out there, and, in fact, it seems like two versions created by two companies, for OSX. I'm not sure which version of Tux Paint (I assume latest) is being compared to which version of Kid Pix.) I'm sending my reply back to Petre, as well as to the K12OSN list (to which I am not currently subscribed, but hopefully a moderator will be kind...), as well as to the 'tuxpaint-devel' mailing list.

One way I've imagined is to create an animated GIF out of the various PNGs, but then I'm not sure how or if we'd want to be able to load the _GIF_ back up for playback in Tux Paint. (And, if MNG were more mature and commonly supported, I'd be suggesting that format, rather than GIF.) > "There are some things [TuxPaint] doesn't have [that KidPix does] that > are useful: > > - Text is not reselectable/movable once you switch to a different > function I'm assuming text in Kid Pix lives in its own, un-touchable world.

I assume you're talking about Tux the Penguin? If so, I certainly would love more 'people' to put into Tux Paint.

See the OPTIONS documentation: http://www.tuxpaint.org/docs/html/OPTIONS.html (Search in that page for the keyword "colorfile".)

Along with Tux Paint Config and/or editing the configuration text file by hand, there is a simply little GUI solution for this that's admittedly not very mature, but should do the trick. See: ftp://ftp.tuxpaint.org/unix/x/tuxpaint/savedir/ Also, how well Tux Paint works out-of-the-box depends on how bizarrely the network/logins are set up.

The tuxpaint-users mailing list is a good start. Checking over the documentation (FAQ, OPTIONS, etc.) can be helpful, too. And, as you've learned... just ask! I'm happy to help!

I've had talks with people in the toy industry about this (which once included myself.) The consensus seems to be that the western kids prefer realistic imagery over cartoonish imagery, whereas asian kids prefer cartoonish imagery. I think a good example of it is Street Fighter II (a Japanese product) vs. Mortal Kombat (an American product). Street Figher II did quite well in the U.S., but Mortal Kombat, with its later entrance into the market (I think) and less-than-smooth fighting sequence, still did quite well in the U.S. market. I don't even remember hearing a mention of Mortal Kombat in Japan or Korea, though that could be because I ran in a different circle. [re: editable text feature] > It really is one of the #1 requested features, though. I'm not sure why, > exactly. It's always from school settings, of course. Probably because people like to change their text. It's something I wanted to do with paint programs when I was little, too. Texts stand out distinctictly as individual objects in my mind that I wish to manipulate as I paint. It wasn't until I discovered poligon drawing programs on Mac and PC (which has text manipulation post-insertion) I realized text manipulation ruins bitmap painting program's paradigm. I'm all for it if the two paradigms can be merged. I'm not sure if it's possible in any simple, elegant manner, though. > > Consider changing the background after something has been drawn. > > Go from white to black.

Maybe it's a flyfish... =p I don't know. Changing background seems reasonable enough thing to do.

If you look at a old vacation images, it might look like changing the background is a big thing (mom and dad in front of famous building, mom and dad in front of famous bridge, ... ;-) but when you create a picture, I don't think it is a normal action in most cases. I think a more interesting feature would be to change which stamps are available, based on which starter image you choose. Underwater-image: fish, submarine, ... Street-picture: cars, people, bicycles, ... Space-picture: ufo, astronaut, space ships, ... Picture of your local school: teachers, pupils, ... With such a feature, it would be possible to set up projects to work with themes, whitout your theme getting drowned among all the other stamps. For instance have a picture of your local park, and stamps with local flowers with a informative text description connected to them. Kind regards, Tore |

The magic can be divided into several categories: actions on the whole image, actions on a small well-defined area (which would work well with the brushes) and actions on a small ill-defined area. Screen space is a serious concern. There is also the need to resist adding complicated features. The UI needs to remain workable for the 3-year-olds. At some point you just have to say "use a grown-up program" or "use a special-purpose tool". > > Realistic stamps - See? People DO like actual photos.

There are numerous other usability problems, some fundamental to the whole idea of a background. Consider changing the background after something has been drawn. Go from white to black. How???? Can it be done without leaving ugly white halos around every object? Remember, Tux Paint alpha blends against the background. FYI this can be made to work, but it greatly changes the CPU requirement.

The typical result is one white woman and one man of African ancestry going by whatever name is currently in fashion.

Do they save to floppies? Have they found floppies to be tolerant of being taken to the gym, cafeteria, bus stop, etc.? Do the drives work fine after reading potato chips? When the floppies go bad, do the kids cry? Are the kids running with admin rights? Are they the ones who keep the computers operating? Elementary schools don't hire good-quality full-time sysadmins.

Full filesystem browsing would be a big disaster. Possibly the installer should allow using the "desktop" directory as the "saved" folder. |

Two cases I myself witnessed: One person couldn't get his floppy to work. It had been in his backpack without its cover (not to mention without any hard box or book to protect it from being damaged), and he had actually managed to get butter on the exposed part of the disc! Another person managed to put his floppy between the two floppy drives (in the narrow opening between the physical boxes) and couldn't get it out again. You don't have to be a small child to get in trouble with floppies ;-) Now they might use memory sticks which at least will survive a lot more than a floppy. A friend forgot to remove his memory stick from his pocket before putting his trousers into the washing machine, and the memory stick still worked after it was washed. Kind regards, Tore |

I don't _mind_ cartoons, but I think kids are generally more excited about _real_ things. Things they can later try to draw themselves.

How???? Wow, I had never considered that. Of course, I see it from this standpoint: why would you draw fish on a reef, and then suddenly decide you want the skyline behind the fish...? Perhaps I (we?) see Tux Paint more as virtual paper than others (hence the stamps, etc. being 'applied' to the picture, rather than objects that may be moved later.) > > Characters?

He's in my version, near the fire, explosion and lightning. <snip> > It doesn't work all that well for the cop car. Good point, but the cop car is pretty small, and it's a little hard to tell what the stamp is, or how to use it. It's also really only good for that one stamp. (I've considered using some metadata to all stamps to be joined... e.g., the cop car stamp could be linked to the car stamp... to the user, it looks like its own stamp, when in fact it's an amalgamation. Any other vehicle emblem stamps we come up with for the car could also share the car stamp.

It's not the same, but yes, there are animated brushes. That raises a question... does Kid Pix have animated brushes? I'm almost positive it doesn't have directional brushes. It's kind of a silly feature for Tux Paint, and I've never seen it elsewhere.

Nice. And maybe have a small batch script that lives in the Start->All Programs->Tux Paint that actually figures out where the saved folder is, and launches a windows file explorer window there...? -- -bill! bi...@ne... http://www.newbreedsoftware.com/ |

It would be good to find out a lot more about the usage case.
Some random mostly-wrong guesses, one of which may be right:
a. Teachers can not resist correcting bad spelling or math, and
can not stand to let it be.
b. They really want a story+picture program, half word processor.
Normal business software handles this by letting users embed
objects into a word processing document. We can imagine a
Tux Word program that allows this, possibly even starting up
Tux Paint when the user clicks on an image.
c. They really want something more like a CAD program.

Maybe the reef's front overlay starts to get in the way. Maybe you
realize that goldfish don't like salt water. Maybe it's the reef that was
forgotten, and you drew the fish on plain white by mistake.

So what is the expectation? Is it indeed the floppy disk?
It seems they want access control... without doing access control!
Maybe they'd like Tux Paint to use CD-RW media and write
out an index.html file.
