DESCRIPTION

Tux Paint is a drawing program for young children. It is meant to be easy and fun to use. It provides a simple interface and fixed canvas size, and provides access to previous images using a thumbnail browser (i.e., no access to the underlying filesystem). Unlike popular drawing programs like "The GIMP," it has a very limited toolset. However, it provides a much simpler interface, and has entertaining, child-oriented additions such as sound effects.

OPTIONS - INFORMATIONAL
tuxpaint accepts the following options to emit information about the program. It then exits immediately (without opening a graphical window).

--help
    Display short, helpful information about Tux Paint.

--version
    Output the version info.

--verbose-version
    Output the version info and compile-time build options.

--usage
    Display a list of all commandline options.

--copying
    Show the license (GNU GPL) under which Tux Paint is released.

--listfonts
    Display a list of fonts found by Pango (and so available to Tux Paint via --uifont).

OPTIONS - INTERFACE
tuxpaint accepts the following options to alter the interface. They can be used along with, instead of, or to override options set in configuration files. (See below.)

  VIDEO

--fullscreen=yes --fullscreen=native --fullscreen=no --windowed
    Run Tux Paint in full-screen mode at its default -- or a specified -- screen resolution ("--fullscreen=yes"); or in full-screen mode at the system's native resolution ("--fullscreen=native"); or run in a window ("--fullscreen=no" or "--windowed") (default).

--native
    When in fullscreen mode, use the system's default screen resolution.

--WIDTHxHEIGHT
    Run Tux Paint in a particularly-sized window, or at a particular fullscreen resolution (if --native is not used). Default is 800x600. Minimum width is 640. Minimum height is 480. Portrait and landscape orientations are both supported. (Also see --orient, below.)

--orient=landscape --orient=portrait
    If --orient=portrait is set, asks Tux Paint to swap the WIDTH and HEIGHT values it uses for windowed or fullscreen mode, without having to actually change the WIDTH and HEIGHT values in the configuration file or on the command-line. (This is useful on devices where the screen can be rotated, e.g. tablet PCs.)

--allowscreensaver --disablescreensaver
    Normally, tuxpaint disables your screensaver. Use --allowscreensaver to prevent this from happening.

  SOUND

--nosound --sound
    Disable or enable (default) sound.

--nostereo --stereo
    Disable or enable (default) stereo panning support.

  INTERFACE SIZE

--buttonsize SIZE --buttonsize auto
    Adjust the size of the buttons in Tux Paint's user interface, between 24 and 192 pixels (48 is the default, and suitable for displays with 96 to 120dpi pixel density). Use "auto" to have Tux Paint choose a button size based on Tux Paint's window/display size.

--colorsrows=ROWS
    How many rows of color palette buttons to show; useful when using a large color palette, and/or for use with coarse input devices (like eyegaze trackers). It can be between 1 (default) and 3.

  INTERFACE SIMPLIFICATION

--simpleshapes --complexshapes
    Disable or enable (default) the rotation step when using the Shape tool within Tux Paint. When disabled, shapes cannot be rotated; however, the interface is easier (click, drag, release), which can be useful for younger or disabled children.

--nooutlines --outlines
    With "--nooutlines" enabled, much simpler outlines and 'rubber-band' lines are displayed when using the Lines, Shapes, Stamps and Eraser tools. (This can help when Tux Paint is run on slower computers, or displayed on a remote terminal.)

--uppercase --mixedcase
    With "--uppercase" enabled, all text prompts and the Text and Label drawing tools will display only uppercase letters. This is useful for children who are not yet comfortable with the lowercase characterset. Default mode is mixed case.

  INITIAL STAMP SIZE

--stampsize=SIZE --stampsize=default
    Overrides the default size of all stamps, relative to their possible sizes (determined by Tux Paint, based on the dimensions of both the stamps themselves, and the drawing canvas). Valid values are from 0 (smallest) to 10 (largest). Use "--stampsize=default" to let Tux Paint choose on a per-stamp basis (this is the default setting).

  STARTING OUT

--startblank --startlast
    When you start Tux Paint, it loads the last image that was being worked on.
     The "--startblank" option disables this, so it always starts with a blank canvas. The default behavior is "--startlast".

--newcolorslast --newcolorsfirst
    List solid (blank) colors at the end, or beginning (default) of the options displayed when using the New tool to start a new picture.

  CONTROL SIMPLIFICATION

--noquit --quit
    Disable or enable (default) the on-screen Quit button and [Escape] key for quitting Tux Paint. Instead, use the window close button in the titlebar, the [Alt]+[F4] key sequence, or the [Shift]+[Control]+[Escape] key sequence.

--nostamps --stamps
    With "--nostamps" set, Rubber Stamp images are not loaded, so the Stamps tool will not be available. This option can be used to reduce the time Tux Paint takes to load, and reduce the amount of RAM it requires.

--nostampcontrols --stampcontrols
    Disable or enable (default) buttons to control stamps. Controls include mirror, flip, shrink and grow. (Note: Not all stamps will be controllable in all ways.)

--nostamprotation --stamprotation
    Disable or enable (default) the rotation step when placing a stamp in the drawing.

--nomagiccontrols --magiccontrols
    Disable or enable (default) buttons to control Magic tools. Controls include controlling whether a Magic tool is used like a paint brush, or if it affects the entire image at once. (Note: Not all Magic tools will be controllable.)

--nomagicsizes --magicsizes
    Disable or enable (default) Magic size controls. (Note: Not all Magic tools offer size controls.)

--ungroupmagictools --groupmagictools
    Disable or enable (default) grouping of Magic tools.

--noshapecontrols --shapecontrols
    Disable or enable (default) buttons to change the Shape tool's behavior -- shapes expanding from the center, or from a corner, where the mouse is initially clicked.

--nolabel --label
    Disable or enable (default) the Label tool, which lets you create text which can be altered or moved later.

--nobrushspacing --brushspacing
    Disable or enable (default) the brush spacing option of the Paint and Lines tools, which allows you to override the default spacing of a brush.

--complexity=advanced --complexity=beginner --complexity=novice
    Set the complexity (expertise) level, which affects whether certain Magic tools are available, or how they operate. (advanced is the default)

--notemplateexport --templateexport
    Disable or enable (default) the ability to create new Templates from saved drawings via the Open dialog.

--noerase --erase
    The --noerase option disables Tux Paint's ability to erase files (saved drawings, via the Open dialog, and exported templates, via the New dialog). Useful to prevent a user from accidentally erasing their own work, or that of others (especially used in combination with --saveovernew).

OPTIONS - CONTROLLING TUX PAINT
tuxpaint accepts the following options to alter how you control Tux Paint. They can be used along with, instead of, or to override options set in configuration files. (See below.)

  CURSOR

--nofancycursors --fancycursors
    Disable or enable (default) the 'fancy' mouse pointer shapes in Tux Paint. While the shapes are larger, and context sensitive, some environments have trouble displaying the mouse pointer, and/or leave 'trails' on the screen.

--hidecursor --showcursor
    Completely hide, or enable (default) the mouse pointer in Tux Paint. This can be useful on touchscreen devices, such as tablet PCs.

  KEYBOARD

--noshortcuts --shortcuts
    If "--noshortcuts" mode, keyboard shortcuts (e.g., [Ctrl]+[S] for Save) will be disabled. Default mode is for shortcuts to be enabled.

  MOUSE AND ACCESSIBILITY

--grab --dontgrab
    Grab the mouse and keyboard input (if possible), so that the mouse is confined to the Tux Paint window. Default is to not grab.

--nowheelmouse --wheelmouse
    By default, the wheel (jog dial) on a mouse will be used to scroll the completely ignored, with the "--nowheelmouse" option. This is useful for children who aren't yet comfortable with the mouse. Default is to support the wheel.

--mouse-accessibility
    In this mode, instead of clicking, dragging and releasing (e.g., to draw), you click, move, and click again to end the motion. ("Sticky mouse clicks.")

--keyboard --mouse
    The "--keyboard" option lets the mouse pointer in Tux Paint be controlled with the keyboard. The [Up], [Down], [Left], and [Right] arrow keys move the pointer. [Spacebar] acts as the mouse button.

--nobuttondistinction --buttondistinction
    By default, only mouse button #1 (typically the leftmost mouse button on mice with more than one button) can be used for interacting with Tux Paint.
     With the "--nobuttondistinction" option, mouse buttons #2 (middle) and #3 (right) can be used, as well. This is useful for children who aren't yet comfortable with the mouse. Default is to only recognize button #1.

  ONSCREEN KEYBOARD

--onscreen-keyboard
    Presents a clickable on-screen keyboard when using the Text and Label tools.

--onscreen-keyboard-layout LAYOUT
    Specify the default layout for the on-screen keyboard (see above).

--onscreen-keyboard-disable-change
    Disables the left/right arrow buttons visible on the on-screen keyboard, which are used to switch between the available on-screen keyboard layouts.

  JOYSTICK

--joystick-dev=DEVICE
    Specify which joystick device should be used by Tux Paint. Default value is 0 (the first joystick).

--joystick-dev=list
    List the system's available joysticks and exit. (Does not launch Tux Paint.)

--joystick-slowness=SPEED
    Sets a delay at each axis motion, allowing to slow the joystick. Allowed values are from 0 to 500. Default value is 15.

--joystick-threshold=THRESHOLD
    Sets the minimum level of axis motion to start moving the pointer. Allowed values are from 0 to 32766. Default value is 3200.

--joystick-maxsteps=STEPS
    Sets the maximum pixels the pointer will move at once. Allowed values are from 1 to 7. Default value is 7.

--joystick-hat-timeout=MILLISECONDS
    Sets the delay after wich the pointer will start moving automatically if the hat is keeped pushed. Allowed values are from 0 to 3000. Default value is 1000.

--joystick-hat-slowness=SPEED
    Sets a delay at each automatic motion, allowing to slow the speed of the hat. Allowed values are from 0 to 500. Default value is 15.

--joystick-btn-escape=BUTTON
    Selects the joystick button number, as seen by SDL, that will be used to generate a escape event. Useful to dismiss dialogs and quit.

--joystick-btn-COMMAND=BUTTON
    Selects the joystick button number, as seen by SDL, that will be a shortcut to various tools within Tux Paint.

    -   brush | Paint
    -   stamp | Stamp
    -   lines | Lines
    -   shapes | Shapes
    -   text | Text
    -   label | Label
    -   magic | Magic
    -   undo | Undo
    -   redo | Redo
    -   eraser | Eraser
    -   new | New
    -   open | Open
    -   save | Save
    -   pgsetup | Print (dialog)
    -   print | Print (immediate)

--joystick-buttons-ignore=BUTTON1,BUTTON2,...
    A set of joystick button numbers, as seen by SDL, that should be ignored. Otherwise, unless they are used by one of the "--joystick-btn-..." options above, buttons will be seen as a mouse left-click. Comma-separated.

OPTIONS - PRINTING
tuxpaint accepts the following options to alter how Tux Paint handles printing. They can be used along with, instead of, or to override options set in configuration files. (See below.)

  PRINT PERMISSIONS

--noprint --print
    Disable or enable (default) the Print command within Tux Paint.

--printdelay=SECONDS --printdelay=0
    Only allow printing (via the Print command) once every SECONDS seconds. Default is 0 (no limitation).

  SHOW PRINTER DIALOG

--altprintmod --altprintnever --altprintalways
    These options control whether an system printer dialog appears when the user clicks the Print button. By default ("--altprintmod"), pressing [Alt] while clicking Print will bring up a dialog (unless you're in fullscreen mode). With "--altprintalways", the dialog will always appear, even if [Alt] is not being held. With "--altprintnever", the dialog will never appear, even if [Alt] is being held.

  SAVE PRINTER CONFIGURATION

--printcfg --noprintcfg
    (Windows and Mac OS X only.) Enable or disable loading and saving of printer settings. By default, Tux Paint will print to the default printer with default settings. Pressing [Alt] while pushing the Print button will cause a printer dialog to appear (as long as you're not in fullscreen mode; see also "--altprintalways" and "--altprintnever", below.) Unless "--noprintcfg" is used, your previous settings will be loaded when Tux Paint starts up, and setting changes will be saved for next time.

  PRINT COMMANDS

--printcommand COMMAND
    (Only when PostScript printing is used.) Have Tux Paint print via an alternate command, rather than lpr(1).

--altprintcommand COMMAND
    (Only when PostScript printing is used.) Have Tux Paint print via an alternate command, when a dialog is expect (e.g., when holding [Alt] while clicking Print; see above), rather than kprinter.

  PAPER SIZE

--papersize PAPERSIZE
    (Only when PostScript printing is used.) Ask Tux Paint to generate PostScript of a particular paper size. Valid sizes are those supported by libpaper. See papersize(5).

OPTIONS - SAVING
tuxpaint accepts the following options to alter how Tux Paint operates when saving or exporting drawings. They can be used along with, instead of, or to override options set in configuration files. (See below.)

  SAVE OVER EARLIER WORK

--saveover --saveovernew --saveoverask
    If, when saving a picture, an older version of the file will be overwritten, Tux Paint will, by default, ask for confirmation: either save over the old file, or create a new file. This prompt can be disabled with "--saveover" (which always saves over older versions of pictures) or "--saveovernew" (which always saves a new file). The default is to prompt ("--saveoverask").

  SAVE AND EXPORT DIRECTORIES

--savedir DIR
    Specify where Tux Paint should save and load its drawings.

--exportdir DIR
    Specify where Tux Paint should export drawings and animations.

  MORE SAVING OPTIONS

--nosave --save
    The --nosave option disables Tux Paint's ability to save files. This can be used in situations where the program is only being used for fun, or in a test environment.

--autosave --noautosave
    The --autosave option prevents Tux Paint from asking whether you want to save the current picture when quitting, and assumes you do.

--reversesort --noautosave
    The --reversesort option causes Tux Paint's Open and Slideshow dialogs to display the oldest images at the top of the list (normally the newest appear at the top, and the oldest at the bottom.

OPTIONS - DATA FILES
tuxpaint accepts the following options to alter where Tux Paint loads data (stamps, brushes, etc.) They can be used along with, instead of, or to override options set in configuration files. (See below.)

--datadir DIR
    Specify where Tux Paint should look for personal data files (brushes, stamps, etc.).

--colorfile FILE
    This option allows you to override the default color palette in Tux Paint and replace it with your own. The file should be a plain ASCII text file containing one color description per line. Colors may be in decimal or 6- or 3-digit hexadecimal, and followed by a description. (For example, "#000 Black" and "255 192 64 Orange".)

OPTIONS - LANGUAGE
tuxpaint accepts the following options to alter the language used by Tux Paint's interface, and other related settings. They can be used along with, instead of, or to override options set in configuration files. (See below.) Various parts of Tux Paint have been translated into numerous languages. Tux Paint will try its best to honor your locale setting (i.e., the "LANG" environment variable), if possible. You can also specifically set the language using options on the command-line or in a configuration file.

--locale LOCALE
    Specify the language to use, based on locale name (which is typically of the form "language[_territory][.codeset][@modifier], where "language" is an ISO 639 language code, "territory" is an ISO 3166 country code, and "codeset" is a character set or encoding identifier like "ISO-8859-1" or "UTF-8".)

    For example, "de_DE@euro" for German, or "pt_BR" for Brazilian Portuguese.

--lang LANGUAGE
    Specify the language to use, based on the language's name (as recognized by Tux Paint). Choose one of the language names listed below:

    -   english | american-english
    -   acholi | acoli

--mirrorstamps --dontmirrorstamps
    With "--mirrorstamps" set, stamps which can be mirrored will appear mirrored by default. This can be useful when used by people who prefer things right-to-left over left-to-right.

  FONTS

--nosysfonts --sysfonts
    Tux Paint normally attempts to search for additional TrueType Fonts installed in common places on your system. If this causes trouble, or you'd prefer to only make fonts installed in Tux Paint's directory available, use the "--nosysfonts" option to disable this feature.

--alllocalefonts --currentlocalefont
    Tux Paint avoids loading any fonts found in its "locale" font subdirectory, except any that match the current locale Tux Paint is running under. Use the "--alllocalefonts" option to load all such fonts, for use in the Text and Label tools. (This was the default behavior, prior to version 0.9.21.)

--uifont="FONT NAME" --uifont=default
    Specify the name of a font for Tux Paint to attempt to use for its user interface (UI) -- button labels, dialog pop-up text, instructional text at the bottom. If left unspecified, or "default" is given, then "DejaVu Sans" will be used. (This was the default behavior, prior to version 0.9.31.)

OPTIONS - MISCELLANEOUS
tuxpaint accepts the following options to alter its behavior. They can be used along with, instead of, or to override options set in configuration files. (See below.)

--nosysconfig
    With this option, Tux Paint will not attempt to read the system-wide configuration file (typically "/etc/tuxpaint/tuxpaint.conf" or "/usr/local/etc/tuxpaint/tuxpaint.conf").

--nolockfile
    By default, Tux Paint uses a lockfile (stored in the user's local Tux Paint directory) which prevents it from being launched more than once in 30 seconds. (Sometimes children get too eager, or user interfaces only require one click, but users think they need to double-click.) This option makes Tux Paint ignore the current lockfile.

ENVIRONMENT
While Tux Paint may refer to a number of environment variables indirectly (e.g., via SDL(3)), it directly accesses the following: (See "FILES" below, as well.)

HOME
    to determine where picture files go when using the Save and Open commands within Tux Paint, to keep track of the current image, when quitting and restarting Tux Paint, and to get the user's configuration file.

LANG, LC_ALL, LANGUAGE, and LC_MESSAGES
    to determine language to use, if setlocale(3) refers to "LC_MESSAGES".

SDL_VIDEO_ALLOW_SCREENSAVER
    Set this environment variable to '1' to allow a screensaver to appear while Tux Paint is running. This can also be done via the "--allowscreensaver" option.

SDL_VIDEO_WINDOW_POS
    If this is NOT set, Tux Paint will set it to "center", to attempt to place the Tux Paint window in the center of a display. If it IS set (e.g., to "nopref", meaning "no preference"), Tux Paint will not override it.

FILES

[/usr/local/]/etc/tuxpaint/tuxpaint.conf
    System-wide configuration file. It is read first (unless the "--nosysconfig" option was given on the command-line).

    (Created during installation.)

$HOME/.tuxpaintrc
    User's configuration file. It can be used to set default options (rather than setting them on the command-line every time), and/or to override any settings in the system-wide configuration file.

    (Not created or edited automatically; must be created manually. You can do this by hand, or use tuxpaint-config(1).)

$HOME/.tuxpaint/saved/
    A directory of previously-saved images (and thumbnails). Only files in this directory will be made available using the Open command within Tux Paint. Overridden via the "--savedir" option.

    (Created when Save command is used.)

$HOME/.tuxpaint/current_id.txt
    A reference to the image which was being edited when Tux Paint was last quit. (This image is automatically loaded the next time Tux Paint is re-run, unless the "--startblank" option is set.)

    (Created when Tux Paint is Quit.)

$HOME/.tuxpaint/lockfile.dat
    A lockfile that prevents Tux Paint from being launched more than once every 30 seconds. Disable checking the lockfile by using the "--nolockfile" option.

    (There's no reason to delete the lockfile, as it contains a timestamp inside which causes it to expire after 30 seconds.)

$XDG_CONFIG_HOME[XDG_PICTURES_DIR]/TuxPaint/
    A directory where images and animations should be exported (via options found in Tux Paint's Open dialog), if the "--exportdir" option is not used to override it. If "$XDG_CONFIG_HOME" is set, a configuration file "user-dirs.dirs" will be scanned within the directory it points to; if not, Tux Paint will attempt to do so within "$HOME/.config/". If a setting named "XDG_PICTURES_DIR" is found, it will be used as the location to export images. If all else fails, then "$HOME/Pictures/" will be used. A "TuxPaint" subdirectory will be created.

$XDG_DATA_HOME/Trash/ or $HOME/.local/share/Trash/
    A directory where images are placed when the Erase option is used from the Open dialog.
