# OCRmyPDF-AppImage [](https://travis-ci.com/FPille/OCRmyPDF-AppImage)
|
||||
[AppImage][APPIMAGE] for [OCRmyPDF][OCRMYPDF]
|
||||
|
||||
## Usage
|
||||
Download OCRmyPDF*.AppImage, make it executable and run it.
|
||||
```
|
||||
wget https://github.com/FPille/OCRmyPDF-AppImage/releases/download/continuous/OCRmyPDF-8.3.2-x86_64.AppImage
|
||||
chmod +x OCRmyPDF*.AppImage
|
||||
./OCRmyPDF*.AppImage --help
|
||||
```
|
||||
|
||||
Beside OCRmyPDF additional command line programs can be run with this AppImage like:
|
||||
* img2pdf
|
||||
* ghostscript
|
||||
* pngquant
|
||||
* python3.6
|
||||
* qpdf
|
||||
* tesseract
|
||||
* unpaper
|
||||
|
||||
Just use the program name as first parameter plus options:
|
||||
```
|
||||
./OCRmyPDF*.AppImage tesseract -v
|
||||
tesseract 4.1.0
|
||||
leptonica-1.76.0
|
||||
libjpeg 8d (libjpeg-turbo 1.3.0) : libpng 1.2.50 : libtiff 4.0.3 : zlib 1.2.11 : libwebp 0.4.0 : libopenjp2 2.3.0
|
||||
Found AVX2
|
||||
Found AVX
|
||||
Found SSE
|
||||
```
|
||||
Or create a symlink for the corresponding program:
|
||||
```
|
||||
ln -s OCRmyPDF*.AppImage tesseract
|
||||
./tesseract --list-langs
|
||||
```
