Re: [Tuxpaint-devel] Magic API updated: switchin() and switchout()

[Bill K. <nb...@so...>]

I understand the jist, but could you give me an example chunk of code
(within a Magic tool) where this is used, so I can make sure I do it
properly?  (I don't want to forget to do this, which I will in a matter
of days :^/ )

Oh, I was asking Luc (Begasus).  He may be using the latest Tux Paint code
from CVS (which now needs 'swithcin/switchout' functions in the Magic tools),
which your Magic code might not have yet.

Hi Adam,

Nice to see your admitions, creating new tools for TuxPaint is always nice.
Now on to porting the source to BeOS/ZETA in my case, I just had to add a few 
brackekts {} in the source to make them compile. After that compiling and 
installing works fine.
I don't see the tools showing up in the magic tools section when starting 
TuxPaint though.

Anyway will keep you informed on porting issues and fixes if you need them. 
Keep up the good work! 

Greets,

Luc

Quick, before this feature gets abused, add this:

Each history level should have a void* that can be
filled in by a tool, and a void(fn*)(void*,etc) that gets
called when the history level is destroyed. This would
allow tool-private data.

For example, suppose I paint with bricks. At long as
the top-most history level is the bricks tool, I want to
keep using the same old brick connectivity map. When
the user draws with something else, I need a fresh map.
If the user reverts via undo however, I want my old map.

Hi Vicki - this is more of a question for 'tuxpaint-users', but I'll
answer it here on 'tuxpaint-devel'.  (I'm also Cc'ing Vicki since it looks
like she's not actually subscribed to the list; at least not with the
address she tried to post from.)

Unfortunately, the Slide Show tool is pretty basic.  No sound effects.
At some point in the future, I'd like to make a completely separate
presentation/animation program that integrates with Tux Paint, and it would
have this feature and, obviously, much more.  I'd also like to add
sound-recording support, if possible. :)

As for changing the action sounds in Tux Paint, yes this is possible.
They are simply a collection of OGG (or perhaps some are also still WAV)
sound files that live in Tux Paint's folder.

What platform are you using Tux Paint on?  (Windows?  Mac?  Linux?)

Thanks and good luck!

[Tuxpaint-devel] Magic API updated: switchin() and switchout()

[Bill K. <nb...@so...>]

Magic Tools now receive calls to "switchin()" and "switchout()" functions
to tell them when they are being activated and deactivated.

Currently, deactivation includes when temporary events happen,
such as the user clicking Undo or Redo (or hitting Ctrl-Z, etc.),
or using Open, Save, Print, Quit, etc. functionality.
Activation occurs when those activities are finished.

I haven't tested it much, I just added some printf() to one of my tools
to check when the functions are called, but it seems to work.

Please do "cvs update -dPC" to grab the latest from the main CVS
repository.  (GSOC folks in their own branches/sandboxes/whatever,
please talk to your mentor about how to grab this.)

This won't be all -- I plan to add a UI and API for "paint or entire-image"
modes for Magic tools.  But... dinner time!

Adam - it is time for mid-term evaluations.  Do you have code that you can

Also, I'd appreciate some feedback on what you (and everyone else

[Tuxpaint-devel] TuxPaint Question

[Vicki A. <abe...@gm...>]

Hi,

I'm helping at a university and we're helping rural teachers in computer 
science.  We are using Tuxpaint to show the elementary teachers a 
paint/drawing program that their young ones can use.  The teachers have 
a question, how can one import sound to play while the kids' pictures 
are up or during the slide show?  Also, can they customize the action 
sounds?

Thanks,

Vicki

Well, I think it's unfriendly (and dangerous) to instruct people to
bring up the Windows task manager, since they can (1) lose their work in
Tux Paint if they don't realize that they need to click "End Task", then
click the Tux Paint task to bring it back up, so they can click "Yes"
to Tux Paint's "Quit, are you sure?" prompt, and (2) they can murder all
sorts of other processes.

What's a safe combination on Windows?  Ctrl+Alt+Esc?

I figure that was the intent. The key sequence is built-in
on the Windows platform, already supplied by Microsoft.
Since Linux doesn't have a task manager key sequence
you can rely on, Tux Paint provides a compatible one.

(task manager being how you quit a program that won't
respond to normal quit events)

[Tuxpaint-devel] Tux Paint issues on Windows

[Bill K. <nb...@so...>]

So I'm at my inlaws', and they have a Windows 2000 Professional system
with Tux Paint 0.9.19 installed on it.

I let my ~19 month old son bang around on it in fullscreen mode and
I noticed two very troublesome issues.

(1) Hitting the Windows or Menu key on the keyboard (I'm not sure which,
or if both do it) causes Tux Paint to disappear and the desktop to reappear.
We've discussed this previously, but now that I've seen it in action,
I'd _really_ like to see it fixed soon! :^)

(2) Hitting the Quit key sequence in Tux Paint (for when --noquit is set)
actually brings up the Windows task manager.  (Ctrl+Shift+Escape)
Oops!  Noone ever mentioned this conflict before!

I'll make sure both of these issues are bugged, and will assign them to
John (I hope that's ok!)

[Tuxpaint-devel] Check when magic tool is switched

[Namrata N. <n.n...@gm...>]

I hope that everyone already knows that I am building a character
recognition magic tool as part of GSOC 2008. I have created the part where
characters drawn by using the pen tool are converted to .ink files and are
recognized as language alphabets. This is done through shape recognizer and
hence is completely language (not programming language, but spoken language)
independent.

But now I am building the user interface for my magic tool and I am
encountering few usability issues. I would like some hints and suggestions
from other tuxpaint developers. After the user draws a character using the
pen tool, on what event should the recognition begin? Bill had mentioned
that the user should click on checkbox/button when done. But I have not
found an easy way to create a checkbox/button using magic tools. Another
Idea could be that when another magic tool is selected the recognition
should begin i.e. the user first selects my magic tool called drawText, then
draws a character on the canvas, then clicks on another magic tool, then the
recognition will begin and the character will be displayed as font.

But even a magic_tool_change_event is unavailable through the api. How do
you suggest I can implement this workflow? Any other ideas?

Namrata Nehete.

[Tuxpaint-devel] Corrupted source .tar.gz - sourceforge.net

[foo-script <foo...@o2...>]

The compressed source I downloaded from:
http://sourceforge.net/project/downloading.php?groupname=tuxpaint&filename=tuxpaint-0.9.20.tar.gz

seems to be corrupted. 
After command:

tar -zxvf tuxpaint-0.9.20.tar.gz
an error message occured:

gzip: stdin: invalid compressed data--crc error
tar: Child returned status 1

I tried two different mirrors. The effect is the same. However this problem doesn't make compilation (for Linux) impossible. Everything seems to be OK.

BTW: Yesterday I came back from all-Poland conference in Warsaw-the capitol of Poland. The conference was about information society in Poland and way we create such society. I was talking about education software on GNU/GPL licence (or similar), also about TuxPaint. I showed them some screenshots, sample art galleries, told about capabilities and how to get this software (how to install/download etc...). I also mentioned about Tuxpaint participating in GSoC. Hope TuxPaint will have some more users :) I had only 15 minutes for everything. Next  year I'll have whole an hour :D

This can be the lower level if you implement a level controller for
greyscale.
Also, tuxpaint having yet a colorpicker, it should not be difficult to

specify the colors, being black and white the default.

I agree with you that would be a great idea and there are obviously another
number of tools that would benefit from the ability to control some sort of
variable. Unfortunatly the magic tools api has no facility to have this sort
of feature. I belive that kendrick is very interested in adding this to the
program but its rather singificant proposal.

Are Snow* the same with different images?, if yes, maybe you can join
both and add an image chooser.
I can imagine flowers: adds flowers to the image. fish: adds fishes to
the image. coral: adds corals to the image, sandstorm: adds sand to the

image, etc.

Snowflake does indeed use an image however snowballs simply draws white
circles. It would be great to be able to add other images in a similar
fashion however that would either require lots of tools (a bit messy and
overengineered in my opinion) or a modification to the plugin api to allow
the selection of images inside a magic tool.

I can imagine too they will follow the sparkles evolution from magic to
brush, but I am speaking withouth knowing your work.

some ideas:
rain: like glass tile but with random water drops instead of squares
glass sand: like glass tile but with very small squares or triangles and
saturating the colors.

railroad: draw a railroad, automatically joining rails when crossing

Those sound like some very interesting ideas - I'll definatly look into
them.

Can the number of grey levels be specified in some way?
  I am thinking in something similar to the size controller for stamps.

This can be the lower level if you implement a level controller for
greyscale.

[vudem a. <aru...@gm...>]

hi all,

Mark asked me to post my GSoC project status on the devel list. As
Bill had suggested I am implementing a label tool.  I am implementing
the tool as an option in the current text tool.  Because there will be
only a few more surfaces added, I think that performance will not be
affected much. The basic framework for adding text to a separate layer
has been completed. The layer is transparent except for rendered text
pixels which are opaque. The user interface has also been completed.
There still a little work to be done with regards to the mouse cursor
code. I am currently working on the self referential data structures
to hold the data so that later selection and editing is possible. The
basic selection and editing utility is almost nearing completion. Only
VIDEO_BPP of 32 is supported at the moment.

My next goals in order of priority are:
supporting undo and redo and then to support saving, loading, saving
the data about the layer to support editing across sessions, scaling
which might also be essential for across the session editing,
supporting other bpp.

I'd love to hear your comments and suggestions!

regards,
Arunodai

Keep only the best.

How about a brush with a 3D shaded effect? It would
look kind of like fabric paint, toothpaste, caulking, etc.

How about "vertical wood" and "horizontal wood"?
(tile an image in a hidden buffer, then copy it to the
screen as the user paints)

Try to concentrate on the use case: making art.
Always ask yourself if the tool would be really good
for that. There are some really neat tools that don't
actually do something useful; avoid those.
