Gtans is a tangram game that runs in X. Tangram is a kind of puzzle game where the player
has to arrange a set of pieces to match a given shape.
No command-line options
Use the graphical interface to customize the program. See below.
move the pieces (known as tans) until they match the figure drawn on the right window.
You must always use the seven tans and they should not be laid on top of one another.
To move a tan, click and drag it with left mouse button, for rotation click AROUND it.
You can flip the selected tan by right-clicking. This is usefull for the parallelogram tan
(all positions can not be reached by rotating only).
If you are a beginner to Tangram you should try the first 10 figures. The other ones are
not sorted, some of them are very difficult (to my taste).
When a figure has been solved the background color of the silhouette area changes. The
solved figures are remembered by saving a status file in the user's directory
(~/.gtans/afile.figures.status for a figure file called afile.figures)
Show a tan This button shows the position of a tan. Each further click will display an
Show outline Draw the figure in the main area. This makes the game much easier.
Preferences Most of this menu's options allow you to change the colors used by the game.
For the main area you may choose textures (pixmap files) instead of colors. Some sample
files are supplied (I can't remember where I found them) but as the complete pathname is
saved in the config file you can choose a file located anywhere (for example in
/usr/share/pixmaps/). On a 8 bits display the colors may not be exactly what you want (GTK
tries to find the best matching color).
Preferences/Tans size/Increase Makes the tans 5 % bigger relatively to the game area. If
you resize the window the tans size will be scaled.
Preferences/Tans size/Decrease Makes the tans 4.76 % smaller
Preferences/Accuracy Changes the precision of the comparison between the tans position and
the solution. A lower accuracy makes the game more easy.
Preferences/Rotation Step by step allows only rotation by increment of 11.5 degrees. Con‐
tinuous rotation makes the game more difficult and you probably shouldn't use it unless
you really dislike step by step rotation.
Preferences/Figures file Allows you to choose another figures file.
Preferences/Save config Save a config file in the user's home directory.
Misc/Clear figure status Set the current figure as unsolved.
Misc/Clear all figures status Set all the loaded figures (i.e. from the current figure
file) as unsolved.
~/.gtans/.gtansrc Configuration options for gtans. All of these options
can be set from the interface, there should be no need to edit this file.
~/.gtans/somename.figures.status Status files (for each figures file the
user played with) remenbering which figures where solved.
