NoteShrink
==========
This project makes scans and handwritten notes more beautiful! The program clears synopses and scans from "dirt", improves their readability and reduces the size of the image **up to 10,000 times(!)**.
## Tasks
- [X] Create an algoritm and console app
- [X] Create GUI
- [X] Add scan and print feature
- [ ] Add notes drawing and editing features
- [ ] Add a pen tool
- [ ] Add a text tool
- [ ] Add an eraser tool
- [ ] Add the ability to add more than one page `(30%)`
- [ ] Add the ability to save to PDF
- [ ] Add support for multi-thread processing
- [ ] Translate Python to C/C++ `(25%)`
- [ ] Maybe redraw GUI
- [ ] Create a web site with the same functionality
## Example
#### Input [4.33 Mb]
#### Output [44.1 Kb]
See more examples at [here](/examples)
## Building
### Python
If you want to use the console version you may use only `Python` module. You can compile it to win32 `EXE` file with `cx_Freeze` ([How convert a .py to .exe](https://stackoverflow.com/questions/41570359/how-can-i-convert-a-py-to-exe-for-python)). You may find a python script [here](/PythonModule/noteshrink.py).
#### Requirements for python
- Python 3
- NumPy 1.10 or later
- SciPy
- ImageMagick
- Image module Pillow
#### Usage
```
./noteshrink.py IMAGE1 [IMAGE2 ...]
```
or
```
convert scanned, hand-written notes to PDF
positional arguments:
IMAGE files to convert
optional arguments:
-h, --help show this help message and exit
-q reduce program output
-b BASENAME output PNG filename base (default page)
-o PDF output PDF filename (default output.pdf)
-v PERCENT background value threshold % (default 25)
-s PERCENT background saturation threshold % (default 20)
-n NUM_COLORS number of output colors (default 8)
-p PERCENT % of pixels to sample (default 5)
-w make background white
-g use one global palette for all pages
-S do not saturate colors
-K keep filenames ordered as specified; use if you *really*
want IMG_10.png to precede IMG_2.png
-P POSTPROCESS_CMD set postprocessing command (see -O, -C, -Q)
-e POSTPROCESS_EXT filename suffix/extension for postprocessing command
-O same as -P "optipng -silent %i -out %o"
-C same as -P "pngcrush -q %i %o"
-Q same as -P "pngquant --ext %e %i"
-c COMMAND PDF command (default "convert %i %o")
```
### CShrp
1. Compile `Python` to `EXE`
2. Build C# project
3. Copy a Python `exe`, `dll` file and `lib` folder to `\bin\Debug\` or `\bin\Release\` directory (I'm sorry for this, but I promise I will fix it soon).
### Requirements for CSharp
- Microsoft Visual C++ 2017 Redistributable Package
