If you want to know more about nonograms, you can find more information on Wikipedia.

This small Python script, based on Pygame, can be used to solve nonograms by hand or automatically.
When starting the script you get a small GUI with two enabled open buttons, to open a new, empty nonogram or to open an already (partly) solved one. A right-click opens a pull-down menu that shows the most recently opened files
The file format of a new nonogram is a text file with one line for each row and one line for each column of the nonogram. Row lines start with 'Z' (upper or lower case), column lines with 'S' (upper or lower case) followed by the block lengths. For example, if the first row of the nonogram has two blocks with lengths 3 and 8, the file entry for this row would be is Z 3 8.
The file extension of new nonograms is .nob, partly solved have .nos
Some nonograms are given in the 'Nono_Examples' folder.
After selecting a valid file the nonogram will be displayed on the GUI.
A left mouse click sets a field to black. With a right mouse click a cross will be set and the middle mousebutton clears the field. You can enter a trial (lower left button) mode to test some moves. In this mode the blocks and crosses will be drawn in red. If you think the red block are correct you can turn all red blocks to black (second lower button). The third lower button deletes all red trial blocks and crosses.
When clicking left on a block length value (left / above the nonogram board) it will be marked with a cross to set this block as completed. With a right click the cross can be removed.
Following key shortcuts are available:
| Key | Function |
|---|---|
| T | Change to trial mode |
| N | Change to normal mode |
| Ctrl + W | Clear all red blocks/crosses |
| Ctrl + B | Set all red blocks/crosses to black |
| Ctrl + Z | Undo |
| Ctrl + Y | Redo |
| Ctrl + A | Fill all overlapping blocks |
| Ctrl + R | Check if blocks/crosses can be set in partially filled rows |
| Ctrl + C | Check if blocks/crosses can be set in partially filled columns |
| Ctrl + S | Solve the nonogram |
Remark: By pressing [Ctrl + A] and alternately [Ctrl + R] and [Ctrl + C], the nonogram will successively be solved
Some user input data (recently opened file, starting directory, ...) will be saved within the environment folder using os.environ['APPDATA'] extendet with "/username/nonogramm". For Windows this will be the directory:
"c:\Users\username\AppData\Roaming\username\Nonogramm".
I do not know what happens on a Linux or Mac OS. If saving files at that location is not desired, the name can be changed in the module "ConfigProperties.py"
