QR code gen app
 

i am looking for a QR image generator app for CentOS. i need to create batches of images (QR codes) in sets of 1000. i will have a list of numbers in a file and i need to send the app every number and app creates a QR code of set size in a image format (jpg, png, bmp, gif).

anyone know of such app?

does this one work ok?

I'm running CentOS 6 and just installed it from the epel repository which has version 3.4.2. Seems to work fine with a quick test although there are known bugs as described in the change logs. qrencode generates a png, if you need the other formats then you can create them using convert which is part of imagemagick.

You should be able to compile it from source and you can write a script to generate batches of qrcodes.

i tried qrencode install on my centOS 6.8 and configure keeps failing libpng check. not sure why, all that stuff is installed.

cli for the utility has -t EPS option. that works for me, but PNG is easier for printer person.

I didn't mention that the default is PNG but version 3.4.2 can output PNG,EPS,SVG,ANSI,ANSI256,ASCII,ASCIIi,UTF8 or ANSIUTF8 formats.

Did you install from a repository or source?

i installed from source, but my issue was PKG_CONFIG_PATH was not a env variable. libpng.pc is in /usr/local/lib/pkgconfig and configure doesnt look here by default !!

all fixed now. now i can just read a line from file and send it to the qr binary via script.

Very good...
