How to install
- Unpack the tar.gz file with "tar xzvf readbarcode-x.x.x.tar.gz" (replace x.x.x with right version number). Change into the dir, and "./configure", make then make install
- If you need a GUI, then download it, and install like above. But you need install Spca5xx first, donot forget the video4linux module.
How to use
- If you use GUI, link your webcam and PC like the photo show below. ( C: your PC USB plug; B: the webcam; A: things with Bar code ) Type "ppmGet" to get start.
- If you ues readbarcode in command line, type
"readbarcode -i inputpic.ppm -p 0.2 -o result.txt -try" will be OK.
-i input picture (ppm format, better at size 640X480)
-o output decode result to a txt file (you need it, because STDOUT is full of debug messages) - Now it can only work with HEX ppm format ( not ascii format, no annotation begin with # ) you'd better use GUI ppmGet to get your ppm picture files ,or samplePIC.ppm and other sample pictures in img directory in the source
