Reduce the size of the image to no wider than 448 pixels
across and no taller than 376 pixels tall. (i.e., the
maximum size is 448 x 376 pixels)
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.

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.
