About this 'How-To'
This 'How-To' assumes that you want to make an excellent Tux Paint
stamp, in PNG bitmapped format, from a JPEG image (e.g., a digital
photograph). There are easier and faster methods that produce lower
quality.

There are easier and faster methods that produce lower quality.
This 'How-To' assumes you are dealing with normal opaque objects.
Dealing with semi-transparent objects (fire, moving fan blade, kid's
balloon) or light-giving objects (fire, lightbulb, sun) is best done
with custom software. Images with perfect solid-color backgrounds are
also best done with custom software, but are not troublesome to do as
follows.

Image Size and Orientation
Image Size and Orientation
You need an image that has a useful orientation. Perspective is an
enemy. Images that show an object from the corner are difficult to fit
into a nice drawing. As a general rule, telephoto side views are the
best. The impossible ideal is that, for example, two wheels of a car
are perfectly hidden behind the other two.

are perfectly hidden behind the other two.
Rotating an image can make it blurry, especially if you only rotate by
a few degrees. Images that don't need rotation are best, images that
need lots of rotation (30 to 60 degrees) are next best, and images
that need just a few degrees are worst. Rotation will also make an
image darker because most image editing software is very bad about
gamma handling. (Rotation is only legitimate for gamma=1.0 images.)

Very large images are more forgiving of mistakes, and thus easier to
work with. Choose an image with an object that is over 1000 pixels
across if you can. You can shrink this later to hide your mistakes.

Pay attention to feet and wheels. If they are buried in something, you
will need to draw new ones. If only one is buried, you might be able
to copy the other one as a replacement.

Prepare the image
First of all, be sure to avoid re-saving the image as a JPEG. This
causes quality loss. There is a special tool called jpegtran that lets
you crop an image without the normal quality loss.

Bring that image up in your image editor. If you didn't crop it yet, you
may find that your image editor is very slow. Rotate and crop the image
as needed. Save the image — choose whatever native format supports
layers, masks, alpha, etc. GIMP users should choose "XCF", and Adobe
Photoshop users should choose "PSD", for example.

start with a selection, or by using the grayscale value of the WIP
layer. You might invert the mask.

Prepare the mask
Get used to doing [Control]-click and [Alt]-click on the thumbnail
images in the layers dialog. You will need this to control what you are
looking at and what you are editing. Sometimes you will be editing
things you can't see. For example, you might edit the mask of the WIP
layer while looking at the unmodified image. Pay attention so you don't
screw up. Always verify that you are editing the right thing.

Set an unmodified image as what you will view (the top one is easiest).
Set the WIP mask as what you will edit. At some point, perhaps not
immediately, you should magnify the image to about 400% (each pixel of
the image is seen and edited as a 4x4 block of pixels on your screen).

Select parts of the image that need to be 100% opaque or 0% opaque. If
you can select the object or background somewhat accurately by color, do
so. As needed to avoid selecting any pixels that should be partially
opaque (generally at the edge of the object) you should grow, shrink,
and invert the selection.

(generally at the edge of the object) you should grow, shrink, and invert

Fill the 100% opaque areas with white, and the 0% opaque areas with
black. This is most easily done by drag-and-drop from the
foreground/background color indicator. You should not see anything
happen, because you are viewing the unmodified image layer while editing
the mask of the WIP layer. Large changes might be noticable in the
thumbnail.

Check your work. Hide the top unmodified image layer. Display just the
mask, which should be a white object on a black background (probably
with unedited grey at the edge). Now display the WIP layer normally, so
that the mask is active. This should show your object over top of the
next highest enabled layer, which should be green or magenta as needed
for maximum contrast. You might wish to flip back and forth between
those backgrounds by repeatedly clicking to enable/disable the green
layer. Fix any obvious and easy problems by editing the mask while
viewing the mask.

Go back to viewing the top unmodified layer while editing the WIP mask.
Set your drawing tool the paintbrush. For the brush, choose a small
fuzzy circle. The 5x5 size is good for most uses.

With a steady hand, trace around the image. Use black around the
outside, and white around the inside. Avoid making more than one pass
without switching colors (and thus sides).

Flip views a bit, checking to see that the mask is working well. When
the WIP layer is composited over the green or magenta, you should see a
tiny bit of the original background as an ugly fringe around the edge.
If this fringe is missing, then you made the object mask too small. The
fringe consists of pixels that are neither 100% object nor 0% object.
For them, the mask should be neither 100% nor 0%. The fringe gets
removed soon.

View and edit the mask. Select by color, choosing either black or white.
Most likely you will see unselected specks that are not quite the
expected color. Invert the selection, then paint these away using the
pencil tool. Do this operation for both white and black.

Replace the fringe and junk pixels
Still viewing the mask, select by color. Choose black. Shrink the
selection by several pixels, being sure to NOT shrink from the edges of
the mask (the shrink helps you avoid and recover from mistakes).

Now disable the mask. View and edit the unmasked WIP layer. Using the
color picker tool, choose a color that is average for the object.
Drag-and-drop this color into the selection, thus removing most of the

This solid color will compress well and will help prevent ugly color
fringes when Tux Paint scales the image down. If the edge of the object
has multiple colors that are very different, you should split up your
selection so that you can color the nearby background to be similar.

To reduce accidents, you may wish to select only those pixels that are
not grey in the mask. (Select by color from the mask, choose black, add
mode, choose white, invert. Alternately: Select all, select by color
from the mask, subtract mode, choose black, choose white.) If you do
this, you'll probably want to expand the selection a bit and/or hide the
"crawling ants" line that marks the selection.

Use the clone tool and the brush tool. Vary the opacity as needed. Use
small round brushes mostly, perhaps 3x3 or 5x5, fuzzy or not. (It is
generally nice to pair up fuzzy brushes with 100% opacity and non-fuzzy
brushes with about 70% opacity.) Unusual drawing modes can be helpful
with semi-transparent objects.

The goal is to remove the edge fringe, both inside and outside of the
object. The inside fringe, visible when the object is composited over
magenta or green, must be removed for obvious reasons. The outside
fringe must also be removed because it will become visible when the
image is scaled down. As an example, consider a 2x2 region of pixels at
the edge of a sharp-edged object. The left half is black and 0% opaque.
The right half is white and 100% opaque. That is, we have a white object
on a black background. When Tux Paint scales this to 50% (a 1x1 pixel
area), the result will be a grey 50% opaque pixel. The correct result
would be a white 50% opaque pixel. To get this result, we would paint
away the black pixels. They matter, despite being 0% opaque.

Tux Paint can scale images down by a very large factor, so it is
important to extend the edge of your object outward by a great deal.
Right at the edge of your object, you should be very accurate about
this. As you go outward away from the object, you can get a bit sloppy.
It is reasonable to paint outward by a dozen pixels or more. The farther
you go, the more Tux Paint can scale down without creating ugly color
fringes. For areas that are more than a few pixels away from the object
edge, you should use the pencil tool (or sloppy select with
drag-and-drop color) to ensure that the result will compress well.

Save the image for Tux Paint
It is very easy to ruin your hard work. Image editors can silently
destroy pixels in 0% opaque areas. The conditions under which this
happens may vary from version to version. If you are very trusting, you
can try saving your image directly as a PNG. Be sure to read it back in
again to verify that the 0% opaque areas didn't turn black or white,
which would create fringes when Tux Paint scales the image down. If you
need to scale your image to save space (and hide your mistakes), you are
almost certain to destroy all the 0% opaque areas. So here is a better
way...

A Safer Way to Save
A Safer Way to Save
Drag the mask from the layers dialog to the unused portion of the
toolbar (right after the last drawing tool). This will create a new
image consisting of one layer that contains the mask data. Scale this
as desired, remembering the settings you use. Often you should start
with an image that is about 700 to 1500 pixels across, and end up with
one that is 300 to 400.

Save the mask image as a NetPBM portable greymap (".pgm") file. (If
you are using an old release of The GIMP, you might need to convert
the image to greyscale before you can save it.) Choose the more
compact "RAW PGM" format. (The second character of the file should be
the ASCII digit "5", hex byte 0x35.)

Going back to the multi-layer image, now select the WIP layer. As you
did with the mask, drag this from the layers dialog to the toolbar.
You should get a single-layer image of your WIP data. If the mask came
along too, get rid of it. You should be seeing the object and the
painted-away surroundings, without any mask thumbnail in the layers
dialog. If you scaled the mask, then scale this image in exactly the
same way. Save this image as a NetPBM portable pixmap (".ppm") file.
(Note: .ppm, not .pgm.) (If you choose the RAW PPM format, the second
byte of the file should be the ASCII digit "6", hex byte 0x36.)

Storage-related environment variables
HOME
HOME
Specifies the user's "home directory", which is used to locate
numerous other files or directories. In some cases, it is utilized
as part of a fall-back location, when other environment variables
(elsewhere in this documentation) are not set. Sometimes, the
location to use can be overridden by options provided on the
command-line or via Tux Paint's configuration file. See the
"OPTIONS" documentation for details.

XDG_CONFIG_HOME
On Linux and other platforms where the X Desktop Group standards
are used, the location of the user's configuration files.
Specifically, where to find "user-dirs.dirs", where the
"XDG_PICTURES_DIR" might be defined. It is used for exporting
drawings and animated GIFs. Generally it's set to something like
"$HOME/Pictures/". If not specified, Tux Paint checks in the
directory "$HOME/.config/". If the configuration cannot be found,
Tux Paint simply exports drawings and GIFs to "$HOME".

"user-dirs.dirs", where the "XDG_PICTURES_DIR" might be defined. It is used
for exporting drawings and animated GIFs. Generally it's set to something

exports drawings and GIFs to "$HOME".
On Linux and other platforms where the X Desktop Group standards
are used, the location of the user's data directories.
Specifically, where to find the "Trash" directory. It is used when
deleting images from Tux Paint's "Open" dialog. If not set, the
location "$HOME/.local/share/Trash/" is used, if available. If
not, images are simply deleted, rather than moved anywhere.
TEMP
Specifies the location where temporary files may be created. Only
used by Tux Paint on Microsoft Windows OSes. Uses "userdata" if
not set.

About PNGs
About PNGs
PNG is the Portable Network Graphic format. It is an open standard, not
burdened by patents (like GIFs). It is a highly compressed format (though
not "lossy" like JPEGs - lossiness allows files to be much smaller, but
introduces 'mistakes' in the image when saved), and supports 24-bit color
(16.7 million colors) as well as a full "alpha channel" - that is, each
pixel can have a varying degree of transparency.

Tux Paint responds as if the "Quit" button were pressed, or the desktop
environment was told to close Tux Paint (e.g., by clicking a window close

From the main interface, Tux Paint will prompt whether or not you
wish to quit, and (unless overridden by the auto-save option, e.g.
"--autosave") if you'd like to save the current drawing (if
unsaved), and if so, and it's a modified version of an existing
drawing (unless overridden by the options to save over old images,
or always save new images; e.g. "--saveover" and "--saveovernew",

💡 Note: From other parts of the interface, the signal is currently
interpreted as a request to go back (e.g., from the "New" dialog
back to the main interface), as if a "Back" button in Tux Paint
were clicked, or the [Esc] was key pressed.

SIGUSR1 & SIGUSR2
Tux Paint responds by setting its auto-save option (as if it had
been launched with "--autosave"), as well as either the option to
always save new images (as if launched with "--saveovernew") in
the case of receiving a SIGUSR1 signal, or to always save over the
existing image (as if launched with "--saveover") in the case of
receiving SIGUSR2. Then Tux Paint sends itself a SIGTERM signal,
in an attempt to quit. (See above.)
So, from the main interface, Tux Paint should quit almost
immediately, with no questions asked.

Example: killall -s SIGUSR1 tuxpaint
💡 Note: From other parts of the interface, unfortunately, Tux Paint will go

necessary to send this signal to Tux Paint a few times, for it to quit
completely.
