About
|
|
|
|
What Is 'Tux Paint?'
|
|
|
|
Tux Paint is a free drawing program designed for young children (kids
|
|
ages 3 and up). It has a simple, easy-to-use interface, fun sound
|
|
effects, and an encouraging cartoon mascot who helps guide children as
|
|
they use the program. It provides a blank canvas and a variety of
|
|
drawing tools to help your child be creative.
|
|
|
|
License:
|
|
|
|
Tux Paint is an Open Source project, Free Software released under the
|
|
GNU General Public License (GPL). It is free, and the 'source code'
|
|
behind the program is available. (This allows others to add features,
|
|
fix bugs, and use parts of the program in their own GPL'd software.)
|
|
|
|
See COPYING.txt for the full text of the GPL license.
|
|
|
|
Objectives:
|
|
|
|
Easy and Fun
|
|
Tux Paint is meant to be a simple drawing program for young
|
|
children. It is not meant as a general-purpose drawing tool.
|
|
It is meant to be fun and easy to use. Sound effects and a
|
|
cartoon character help let the user know what's going on, and
|
|
keeps them entertained. There are also extra-large
|
|
cartoon-style mouse pointer shapes.
|
|
|
|
Extensibility
|
|
Tux Paint is extensible. Brushes and "rubber stamp" shapes can
|
|
be dropped in and pulled out. For example, a teacher can drop
|
|
in a collection of animal shapes and ask their students to
|
|
draw an ecosystem. Each shape can have a sound which is
|
|
played, and textual facts which are displayed, when the child
|
|
selects the shape.
|
|
|
|
Portability
|
|
Tux Paint is portable among various computer platforms:
|
|
Windows, Macintosh, Linux, etc. The interface looks the same
|
|
among them all. Tux Paint runs suitably well on older systems
|
|
(like a Pentium 133), and can be built to run better on slow
|
|
systems.
|
|
|
|
Simplicity
|
|
There is no direct access to the computer's underlying
|
|
intricacies. The current image is kept when the program quits,
|
|
and reappears when it is restarted. Saving images requires no
|
|
need to create filenames or use the keyboard. Opening an image
|
|
is done by selecting it from a collection of thumbnails.
|
|
Access to other files on the computer is restricted.
|
|
|

|
|
|
Using Tux Paint
|
|
|
|
Loading Tux Paint
|
|
|
|
Linux/Unix Users
|
|
|
|
Tux Paint should have placed a laucher icon in your KDE and/or GNOME
|
|
menus, under 'Graphics.'
|
|
|
|
Alternatively, you can run the following command at a shell prompt
|
|
(e.g., "$"):
|
|
|
|
$ tuxpaint
|
|
|
|
If any errors occur, they will be displayed on the terminal (to
|
|
"stderr").
|
|
|
|
----------------------------------------------------------------------
|
|
|
|
Windows Users
|
|
|
|
[Icon]
|
|
Tux Paint
|
|
|
|
If you installed Tux Paint on your computer using the
|
|
'Tux Paint Installer,' it will have asked you whether you wanted a
|
|
'Start' menu short-cut, and/or a desktop shortcut. If you agreed,
|
|
you can simply run Tux Paint from the 'Tux Paint' section of your
|
|
'Start' menu (e.g., under "All Programs" on Windows XP), or by
|
|
double-clicking the "Tux Paint" icon on your desktop.
|
|
|
|
If you installed Tux Paint using the 'ZIP-file' download, or if you
|
|
used the 'Tux Paint Installer,' but chose not to have shortcuts
|
|
installed, you'll need to double-click the "tuxpaint.exe" icon in
|
|
the 'Tux Paint' folder on your computer.
|
|
|
|
By default, the 'Tux Paint Installer' will put Tux Paint's folder in
|
|
"C:\Program Files\", though you may have changed this when the
|
|
installer ran.
|
|
|
|
If you used the 'ZIP-file' download, Tux Paint's folder will be
|
|
wherever you put it when you unzipped the ZIP file.
|
|
|
|
----------------------------------------------------------------------
|
|
|
|
Mac OS X Users
|
|
|
|
Simply double-click the "Tux Paint" icon.
|
|
|
|
----------------------------------------------------------------------
|
|
|
|
Title Screen
|
|
|
|
When Tux Paint first loads, a title/credits screen will appear.
|
|
|
|
[Title Screenshot]
|
|
|
|
Once loading is complete, press a key or click on the mouse to
|
|
continue. (Or, after about 30 seconds, the title screen will go away
|
|
automatically.)
|
|
|
|
----------------------------------------------------------------------
|
|
|
|
Main Screen
|
|
|
|
The main screen is divided into the following sections:
|
|
|
|
Left Side: Toolbar
|
|
|
|
The toolbar contains the drawing and editing controls.
|
|
|
|
[Tools: Paint, Stamp, Lines, Shapes, Text, Magic, Undo, Redo, Eraser, New,
|
|
Open, Save, Print, Quit]
|
|
|
|
Middle: Drawing Canvas
|
|
|
|
The largest part of the screen, in the center, is the drawing
|
|
canvas. This is, obviously, where you draw!
|
|
|
|
[(Canvas)]
|
|
|
|
Note: The size of the drawing canvas depends on the size of
|
|
Tux Paint. You can change the size of Tux Paint using the
|
|
Tux Paint Config. configuration tool, or by other means. See
|
|
the OPTIONS documentation for more details.
|
|
|
|
Right Side: Selector
|
|
|
|
Depending on the current tool, the selector shows different
|
|
things. e.g., when the Paint Brush tool is selected, it shows
|
|
the various brushes available. When the Rubber Stamp tool is
|
|
selected, it shows the different shapes you can use.
|
|
|
|
[Selectors - Brushes, Letters, Shapes, Stamps]
|
|
|
|
Lower: Colors
|
|
|
|
A palette of available colors are shown near the bottom of the
|
|
screen.
|
|
|
|
[Colors - Black, White, Red, Pink, Orange, Yellow, Green, Cyan, Blue,
|
|
Purple, Brown, Grey]
|
|
|
|
(NOTE: You can define your own colors for Tux Paint. See the
|
|
"Options" documentation.)
|
|
|
|
Bottom: Help Area
|
|
|
|
At the very bottom of the screen, Tux, the Linux Penguin,
|
|
provides tips and other information while you draw.
|
|
|
|
(For example: 'Pick a shape. Click to pick the center, drag, then let go
|
|
when it is the size you want. Move around to rotate it, and click to draw
|
|
it.)
|
|
|
|
----------------------------------------------------------------------
|
|
|
|
Available Tools
|
|
|
|
Drawing Tools
|
|
|
|
Paint (Brush)
|
|
|
|
The Paint Brush tool lets you draw freehand, using various
|
|
brushes (chosen in the Selector on the right) and colors
|
|
(chosen in the Color palette towards the bottom).
|
|
|
|
If you hold the mouse button down, and move the mouse, it
|
|
will draw as you move.
|
|
|
|
As you draw, a sound is played. The bigger the brush, the
|
|
lower the pitch.
|
|
|
|
----------------------------------------------------------------------
|
|
|
|
Stamp (Rubber Stamp)
|
|
|
|
The Stamp tool is like a set of rubber stamps or stickers.
|
|
It lets you paste pre-drawn or photographic images (like a
|
|
picture of a horse, or a tree, or the moon) in your picture.
|
|
|
|
As you move the mouse around the canvas, an outline follows
|
|
the mouse, showing where the stamp will be placed, and how
|
|
big it will be.
|
|
|
|
There can be numerous categories of stamps (e.g., animals,
|
|
plants, outer space, vehicles, people, etc.). Use the Left
|
|
and Right arrows to cycle through the collections.
|
|
|
|
Some stamps can be colored or tinted. If the color palette
|
|
below the canvas is activated, you can click the colors to
|
|
change the tint or color of the stamp before placing it in
|
|
the picture.
|
|
|
|
Stamps can be shrunk and expanded, and many stamps can be
|
|
flipped vertically, or displayed as a mirror-image, using
|
|
controls at the bottom right of the screen.
|
|
|
|
Different stamps can have different sound effects and/or
|
|
descriptive (spoken) sounds. Buttons at the lower left (near
|
|
Tux, the Linux penguin) allow you to re-play the sound
|
|
effects and descriptive sounds for the currently-selected
|
|
stamp.
|
|
|
|
(NOTE: If the "nostampcontrols" option is set, Tux Paint
|
|
won't display the Mirror, Flip, Shrink and Grow controls for
|
|
stamps. See the "Options" documentation.)
|
|
|
|
----------------------------------------------------------------------
|
|
|
|
Lines
|
|
|
|
This tool lets you draw straight lines using the various
|
|
brushes and colors you normally use with the Paint Brush.
|
|
|
|
Click the mouse and hold it to choose the starting point of
|
|
the line. As you move the mouse around, a thin 'rubber-band'
|
|
line will show where the line will be drawn.
|
|
|
|
Let go of the mouse to complete the line. A "sproing!" sound
|
|
will play.
|
|
|
|
----------------------------------------------------------------------
|
|
|
|
Shapes
|
|
|
|
This tool lets you draw some simple filled, and un-filled
|
|
shapes.
|
|
|
|
Select a shape from the selector on the right (circle,
|
|
square, oval, etc.).
|
|
|
|
In the canvas, click the mouse and hold it to stretch the
|
|
shape out from where you clicked. Some shapes can change
|
|
proportion (e.g., rectangle and oval), others cannot (e.g.,
|
|
square and circle).
|
|
|
|
Let go of the mouse when you're done stretching.
|
|
|
|
Normal Mode
|
|
|
|
Now you can move the mouse around the canvas to
|
|
rotate the shape.
|
|
|
|
Click the mouse button again and the shape will
|
|
be drawn in the current color.
|
|
|
|
Simple Shapes Mode
|
|
If simple shapes are enabled (e.g., with the
|
|
"--simpleshapes" option), the shape will be
|
|
drawn on the canvas when you let go of the
|
|
mouse button. (There's no rotation step.)
|
|
|
|
----------------------------------------------------------------------
|
|
|
|
Text
|
|
|
|
Choose a font (from the 'Letters' available on the right)
|
|
and a color (from the color palette near the bottom). Click
|
|
on the screen and a cursor will appear. Type text and it
|
|
will show up on the screen.
|
|
|
|
Press [Enter] or [Return] and the text will be drawn onto
|
|
the picture and the cursor will move down one line.
|
|
|
|
Alternatively, press [Tab] and the text will be drawn onto
|
|
the picture, but the cursor will move to the right of the
|
|
text, rather than down a line, and to the left. (This can be
|
|
useful to create a line of text with mixed colors, fonts,
|
|
styles and sizes: Like this.)
|
|
|
|
Clicking elsewhere in the picture while the text entry is
|
|
still active causes the current line of text to move to that
|
|
location (where you can continue editing it).
|
|
|
|
International Character Input
|
|
|
|
Tux Paint allows inputting characters in
|
|
different languages. Most Latin characters
|
|
(A-Z, n, e, etc.) can by entered directly. Some
|
|
languages require that Tux Paint be switched
|
|
into an alternate input mode before entering,
|
|
and some characters must be composed using
|
|
numerous keypresses.
|
|
|
|
When Tux Paint's locale is set to one of the
|
|
languages that provide alternate input modes, a
|
|
key is used to cycle through normal (Latin
|
|
character) and locale-specific mode or modes.
|
|
|
|
Currently supported locales, the input methods
|
|
available, and the key to toggle or cycle
|
|
modes, are listed below. Note: Many fonts do
|
|
not include all characters for all languages,
|
|
so sometimes you'll need to change fonts to see
|
|
the characters you're trying to type.
|
|
* Japanese - Romanized Hiragana and
|
|
Romanized Katakana - right [Alt]
|
|
* Korean - Hangul 2-Bul - right [Alt] or
|
|
left [Alt]
|
|
* Traditional Chinese - right [Alt] or
|
|
left [Alt]
|
|
* Thai - right [Alt]
|
|
|
|
----------------------------------------------------------------------
|
|
|
|
Magic (Special Effects)
|
|
|
|
The 'Magic' tool is actually a set of special tools. Select
|
|
one of the "magic" effects from the selector on the right.
|
|
Then, depending on the tool, either click and drag around
|
|
the picture, or simply click the picture once, to apply the
|
|
effect.
|
|
|
|
Each 'Magic' tool's instructions are contained within the
|
|
"magic-docs" folder.
|
|
|
|
----------------------------------------------------------------------
|
|
|
|
Eraser
|
|
|
|
This tool is similar to the Paint Brush. Wherever you click
|
|
(or click and drag), the picture will be erased. (This may
|
|
be white, some other color, or to a background picture,
|
|
depending on the picture.)
|
|
|
|
A number of eraser sizes are available, both round and
|
|
square..
|
|
|
|
As you move the mouse around, a square outline follows the
|
|
pointer, showing what part of the picture will be erased to
|
|
white.
|
|
|
|
As you erase, a "squeaky clean" eraser/wiping sound is
|
|
played.
|
|
|
|
----------------------------------------------------------------------
|
|
|
|
Other Controls
|
|
|
|
Undo
|
|
|
|
Clicking this tool will undo the last drawing action. You
|
|
can even undo more than once!
|
|
|
|
Note: You can also press [Control]-[Z] on the keyboard to
|
|
undo.
|
|
|
|
----------------------------------------------------------------------
|
|
|
|
Redo
|
|
|
|
Clicking this tool will redo the drawing action you just
|
|
"undid" with the 'Undo' button.
|
|
|
|
As long as you don't draw again, you can redo as many times
|
|
as you had "undone!"
|
|
|
|
Note: You can also press [Control]-[R] on the keyboard to
|
|
redo.
|
|
|
|
----------------------------------------------------------------------
|
|
|
|
New
|
|
|
|
Clicking the "New" button will start a new drawing. A dialog
|
|
will appear where you may choose to start a new picture
|
|
using a solid background color, or using a 'Starter' image
|
|
(see below). You will first be asked whether you really want
|
|
to do this.
|
|
|
|
Note: You can also press [Control]-[N] on the keyboard to
|
|
start a new drawing.
|
|
|
|
'Starter' Images
|
|
|
|
'Starters' can be like a page from a coloring book (a
|
|
black-and-white outline of a picture, which you can then
|
|
color in), or like a 3D photograph, where you draw the
|
|
bits in between.
|
|
|
|
When you load a 'Starter,' draw on it, and then click
|
|
'Save,' it creates a new picture file (it doesn't
|
|
overwrite the original 'Starter,' so you can use it again
|
|
later).
|
|
|
|
----------------------------------------------------------------------
|
|
|
|
Open
|
|
|
|
This shows you a list of all of the pictures you've saved.
|
|
If there are more than can fit on the screen, use the "Up"
|
|
and "Down" arrows at the top and bottom of the list to
|
|
scroll through the list of pictures.
|
|
|
|
Click a picture to select it, then...
|
|
|
|
* Click the green "Open" button at the lower left of
|
|
the list to load the selected picture.
|
|
|
|
(Alternatively, you can double-click a picture's icon
|
|
to load it.)
|
|
|
|
* Click the brown "Erase" (trash can) button at the
|
|
lower right of the list to erase the selected
|
|
picture. (You will be asked to confirm.)
|
|
|
|
* Click the blue "Slides" (slide projector) button at
|
|
the lower left to go to slideshow mode. See "Slides",
|
|
below, for details.
|
|
|
|
* Or click the red "Back" arrow button at the lower
|
|
right of the list to cancel and return to the picture
|
|
you were drawing.
|
|
|
|
If choose to open a picture, and your current drawing hasn't
|
|
been saved, you will be prompted as to whether you want to
|
|
save it or not. (See "Save," below.)
|
|
|
|
Note: You can also press [Control]-[O] on the keyboard to
|
|
get the 'Open' dialog.
|
|
|
|
----------------------------------------------------------------------
|
|
|
|
Save
|
|
|
|
This saves your current picture.
|
|
|
|
If you haven't saved it before, it will create a new entry
|
|
in the list of saved images. (i.e., it will create a new
|
|
file)
|
|
|
|
Note: It won't ask you anything (e.g., for a filename). It
|
|
will simply save the picture, and play a "camera shutter"
|
|
sound effect.
|
|
|
|
If you HAVE saved the picture before, or this is a picture
|
|
you just loaded using the "Open" command, you will first be
|
|
asked whether you want to save over the old version, or
|
|
create a new entry (a new file).
|
|
|
|
(NOTE: If either the "saveover" or "saveovernew" options are
|
|
set, it won't ask before saving over. See the "Options"
|
|
documentation.)
|
|
|
|
Note: You can also press [Control]-[S] on the keyboard to
|
|
save.
|
|
|
|
----------------------------------------------------------------------
|
|
|
|
Print
|
|
|
|
Click this button and your picture will be printed!
|
|
|
|
On most platforms, you can also hold the [Alt] key (called
|
|
[Option] on Macs) while clicking the 'Print' button to get a
|
|
printer dialog. Note that this may not work if you're
|
|
running Tux Paint in fullscreen mode. See below.
|
|
|
|
Disabling Printing
|
|
|
|
If the "noprint" option was set (either with
|
|
"noprint=yes" in Tux Paint's configuration
|
|
file, or using "--noprint" on the
|
|
command-line), the "Print" button will be
|
|
disabled.
|
|
|
|
See the "Options" documentation.)
|
|
|
|
Restricting Printing
|
|
|
|
If the "printdelay" option was used (either
|
|
with "printdelay=SECONDS" in the configuration
|
|
file, or using "--printdelay=SECONDS" on the
|
|
command-line), you can only print once every
|
|
SECONDS seconds.
|
|
|
|
For example, with "printdelay=60", you can
|
|
print only once a minute.
|
|
|
|
See the "Options" documentation.)
|
|
|
|
Printing Commands
|
|
|
|
(Linux and Unix only)
|
|
|
|
Tux Paint prints by generating a PostScript
|
|
representation of the drawing and sending it to
|
|
an external program. By default, the program
|
|
is:
|
|
|
|
lpr
|
|
|
|
This command can be changed by setting the
|
|
"printcommand" value in Tux Paint's
|
|
configuration file.
|
|
|
|
If the [Alt] key on the keyboard is being
|
|
pushed while clicking the 'Print' button, as
|
|
long as you're not in fullscreen mode, an
|
|
alternative program is run. By default, the
|
|
program is KDE's graphical print dialog:
|
|
|
|
kprinter
|
|
|
|
This command can be changed by setting the
|
|
"altprintcommand" value in Tux Paint's
|
|
configuration file.
|
|
|
|
For information on how to change the printing
|
|
commands, see the "Options" documentation.
|
|
|
|
Printer Settings
|
|
|
|
(Windows and Mac OS X)
|
|
|
|
By default, Tux Paint simply prints to the
|
|
default printer with default settings when the
|
|
'Print' button is pushed.
|
|
|
|
However, if you hold the [Alt] (or [Option])
|
|
key on the keyboard while pushing the button,
|
|
as long as you're not in fullscreen mode, your
|
|
operating system's printer dialog will appear,
|
|
where you can change the settings.
|
|
|
|
You can have the printer configuration changes
|
|
stored by using the "printcfg" option, either
|
|
by using "--printcfg" on the command-line, or
|
|
"printcfg=yes" in Tux Paint's own configuration
|
|
file ("tuxpaint.cfg").
|
|
|
|
If the "printcfg" option is used, printer
|
|
settings will be loaded from the file
|
|
"print.cfg" in your personal folder (see
|
|
below). Any changes will be saved there as
|
|
well.
|
|
|
|
See the "Options" documentation.)
|
|
|
|
Printer Dialog Options
|
|
|
|
By default, Tux Paint only shows the printer
|
|
dialog (or, on Linux/Unix, runs the
|
|
"altprintcommand", e.g., "kprinter" instead of
|
|
"lpr") if the [Alt] (or [Option]) key is held
|
|
while clicking the 'Print' button.
|
|
|
|
However, this behavior can be changed. You can
|
|
have the printer dialog always appear by using
|
|
"--altprintalways" on the command-line, or
|
|
"altprint=always" in Tux Paint's configuration
|
|
file. Or, you can prevent the [Alt]/[Option]
|
|
key from having any effect by using
|
|
"--altprintnever", or "altprint=never".
|
|
|
|
See the "Options" documentation.)

|
|
|
|
Slides (under "Open")
|
|
|
|
The "Slides" button is available in the "Open" dialog. It
|
|
displays a list of your saved files, just like the "Open"
|
|
dialog.
|
|
|
|
Click each of the images you wish to display in a
|
|
slideshow-style presentation, one by one. A digit will
|
|
appear over each image, letting you know in which order they
|
|
will be displayed.
|
|
|
|
You can click a selected image to unselect it (take it out
|
|
of your slideshow).
|
|
|
|
A sliding scale at the lower left of the screen (next to the
|
|
"Play" button) can be used to adjust the speed of the
|
|
slideshow, from slowest to fastest. Choose the leftmost
|
|
setting to disable automatic advancement - you will need to
|
|
press a key or click to go to the next slide (see below).
|
|
|
|
Note: The slowest setting does not automatically advance
|
|
through the slides. Use it for when you want to step through
|
|
them manually.
|
|
|
|
When you're ready, click the "Play" button to begin the
|
|
slideshow. (Note: If you hadn't selected ANY images, then
|
|
ALL images will be played in the slideshow.)
|
|
|
|
During the slideshow, press [Space], [Enter] or [Return] or
|
|
the [Right Arrow], or click the "Next" button at the lower
|
|
left, to manually advance to the next slide. Press [Left] to
|
|
go back to the previous slide.
|
|
|
|
Press [Escape], or click the "Back" button at the lower
|
|
right, to exit the slideshow and return to the slideshow
|
|
image selection screen.
|
|
|
|
Click "Back" in the slideshow image selection screen to
|
|
return to the "Open" dialog.
|
|
|
|
Quit
|
|
|
|
Clicking the "Quit" button, closing the Tux Paint window, or
|
|
pushing the [Escape] key will quit Tux Paint.
|
|
|
|
You will first be prompted as to whether you really want to
|
|
quit.
|
|
|
|
If you choose to quit, and you haven't saved the current
|
|
picture, you will first be asked if wish to save it. If it's
|
|
not a new image, you will then be asked if you want to save
|
|
over the old version, or create a new entry. (See "Save"
|
|
above.)
|
|
|
|
NOTE: If the image is saved, it will be reloaded
|
|
automatically the next time you run Tux Paint!
|
|
|
|
NOTE: The "Quit" button and [Escape] key can be disabled
|
|
(e.g., by selecting "Disable 'Quit' Button" in
|
|
Tux Paint Config. or running Tux Paint with the "--noquit"
|
|
command-line option).
|
|
|
|
In that case, the "window close" button on Tux Paint's title
|
|
bar (if not in fullscreen mode) or the [Alt] + [F4] key
|
|
sequence may be used to quit.
|
|
|
|
If neither of those are possible, the key sequence of
|
|
[Shift] + [Control] + [Escape] may be used to quit. (See the
|
|
"Options" documentation.)
|
|
|
|
Sound Muting
|
|
|
|
There is no on-screen control button at this time, but by
|
|
pressing [Alt] + [S], sound effects can be disabled and
|
|
re-enabled (muted and unmuted) while the program is running.
|
|
|
|
Note that if sounds are completely disabled (e.g., by
|
|
unselecting "Enable Sound Effects" in Tux Paint Config or
|
|
running Tux Paint with the "--nosound" command-line option),
|
|
the [Alt] + [S] key sequence has no effect. (i.e., it cannot
|
|
be used to turn on sounds when the parent/teacher wants them
|
|
disabled.)
|

|
Loading Other Pictures into Tux Paint
|
|
|
|
Since Tux Paint's 'Open' dialog only displays pictures you created with
|
|
Tux Paint, what if you want to load some other picture or photograph
|
|
into Tux Paint to edit?
|
|
|
|
To do so, you simply need to convert the picture into a PNG (Portable
|
|
Network Graphic) image file, and place it in Tux Paint's "saved"
|
|
directory:
|
|
|
|
Windows
|
|
Inside the user's "Application Data" folder, e.g.: "C:\Documents
|
|
and Settings\(user name)\Application Data\TuxPaint\saved\"
|
|
|
|
Mac OS X
|
|
Inside the user's "Library" folder:
|
|
"/Users/(user name)/Library/Application
|
|
Support/Tux Paint/saved/"
|
|
|
|
Linux/Unix
|
|
Inside a hidden ".tuxpaint" directory, in the user's home
|
|
directory: "$(HOME)/.tuxpaint/saved/"
|
|
|
|
Using 'tuxpaint-import'
|
|
|
|
Linux and Unix users can use the "tuxpaint-import" shell script which
|
|
gets installed when you install Tux Paint. It uses some NetPBM tools
|
|
to convert the image ("anytopnm"), resize it so that it will fit in
|
|
Tux Paint's canvas ("pnmscale"), and convert it to a PNG ("pnmtopng").
|
|
|
|
It also uses the "date" command to get the current time and date,
|
|
which is the file-naming convention Tux Paint uses for saved files.
|
|
(Remember, you are never asked for a 'filename' when you go to Save or
|
|
Open pictures!)
|
|
|
|
To use 'tuxpaint-import', simply run the command from a command-line
|
|
prompt and provide it the name(s) of the file(s) you wish to convert.
|
|
|
|
They will be converted and placed in your Tux Paint 'saved' directory.
|
|
(Note: If you're doing this for a different user - e.g., your child,
|
|
you'll need to make sure to run the command under their account.)
|
|
|
|
Example:
|
|
|
|
$ tuxpaint-import grandma.jpg
|
|
grandma.jpg -> /home/username/.tuxpaint/saved/20020921123456.png
|
|
jpegtopnm: WRITING A PPM FILE
|
|
|
|
The first line ("tuxpaint-import grandma.jpg") is the command to run.
|
|
The following two lines are output from the program while it's
|
|
working.
|
|
|
|
Now you can load Tux Paint, and a version of that original picture
|
|
will be available under the 'Open' dialog. Just double-click its icon!
|
|
|
|
Doing it Manually
|
|
|
|
Windows, Mac OS X and BeOS users must currently do the conversion
|
|
manually.
|
|
|
|
Load a graphics program that is capable of both loading your picture
|
|
and saving a PNG format file. (See the documentation file "PNG.txt"
|
|
for a list of suggested software, and other references.)
|
|
|
|
When Tux Paint loads an image that's not the same size as its drawing
|
|
canvas, it scales (and sometimes smears the edges of) the image so
|
|
that it fits within the canvas.
|
|
|
|
To avoid having the image stretched or smeared, you can resize it to
|
|
Tux Paint's canvas size. This size depends on the size of the
|
|
Tux Paint window, or resolution at which Tux Paint is run, if in
|
|
fullscreen. (Note: The default resolution is 800x600.) See
|
|
"Calculating Image Dimensions", below.
|
|
|
|
Save the picture in PNG format. It is highly recommended that you name
|
|
the filename using the current date and time, since that's the
|
|
convention Tux Paint uses:
|
|
|
|
YYYYMMDDhhmmss.png
|
|
|
|
* YYYY = Year
|
|
* MM = Month (01-12)
|
|
* DD = Day (01-31)
|
|
* HH = Hour, in 24-hour format (00-23)
|
|
* mm = Minute (00-59)
|
|
* ss = Second (00-59)
|
|
|
|
e.g.:
|
|
|
|
20020921130500 - for September 21, 2002, 1:05:00pm
|
|
|
|
Place this PNG file in your Tux Paint 'saved' directory. (See above.)
|
|
|
|
Calculating Image Dimensions
|
|
|
|
The width of Tux Paint's canvas is simply the width of the window
|
|
(e.g., 640, 800 or 1024 pixels), minus 192.
|
|
|
|
Calculating the height of Tux Paint's canvas requires multiple
|
|
steps:
|
|
1. Take the height of the window (e.g, 480, 600 or 768 pixels) and
|
|
subtract 144
|
|
2. Take the result of Step 1 and divide it by 48
|
|
3. Take the result of Step 2 and round it down (e.g., 9.5 becomes
|
|
simply 9)
|
|
4. Take the result of Step 3 and multiply it by 48
|
|
5. Finally, take the result of Step 4 and add 40
|
|
|
|
Example: Tux Paint running at fullscreen on a 1440x900 display.
|
|
* The canvas width is simply 1440 - 192, or 1248.
|
|
* The canvas height is calculated as:
|
|
1. 900 - 144, or 756
|
|
2. 756 / 48, or 15.75
|
|
3. 15.75 rounded down, or 15
|
|
4. 15 * 48, or 720
|
|
5. 720 + 40, or 760
|
|
So the canvas within a 1440x900 Tux Paint window is 1248x760.
