Bored by Scribble I have written an alternative handwriting for readers with sensor: PB PRO series 603, 903, 612, 622, 912.
You can draw with 5 types of thick lines - selectable in the palette vertically.
Colour (16 shades of gray) can be selected in the palette horizontally.
Black and white drawn faster than a semitone.
Files are automatically saved like "/My Pictures/pbdraw1.bmp".
The files will not be overwritten, after editing the new file is created.
You can choose and open previously saved file using the "next page" - "previous page" or by menu(3 and 4 buttons).
1-st button - New (without saving);
2 - to delete last opened file;
5 - the main freehand drawing mode;
6 - drawing lines by mark at the start and end points;
7 - "tonal brush" of five sizes with a given "color";
8 - filled square;
9 - one-level UNDO;
10 - close with saving.
You can edit the screenshots files. Put it to the folder "/ My Pictures" and rename the file to "pbdraw1.bmp" with the next available number in place of sequence.
