In an earlier posting I wrote, that I wanted to have a simple way to convert a few lines of plain-old-basic text, into an SVG-Image-File. In that posting I had created a set of templates, which would do so from the command-line, but which nevertheless required that the user do some work.
I also explained that the font-family “Liberation” needed to be installed on the machine, in order for that exact variant of the templates to be valid. And of course, ‘Inkscape’ must also be installed.
Well under Linux, if we’re given such templates, we can next proceed to write a shell-script, which does all the work for us, of assembling the templates, and then of executing some jobs.
Therefore, the only logical conclusion now was, that I created a Shell-Script, which I can enter as a command with the base-name, as the parameter to the script (without any .svg or .png extension), and which will expect some text from the standard input – Initially no more than 6 lines of 25 characters – and which creates the SVG as well as the PNG -Files. This script now works as expected. One finishes entering text with <Ctrl>+D .
The previous article described the theoretical basis on which this script works, and now I’m sharing the script with my readers – who are using Linux.

I’ve refined my script, so that it allows the user to specify, optionally, a different text-color, a larger image-size if needed, and an external text-file to use as input, in that order. Also, my code now preserves spaces in the input-text, and escape-codes certain dangerous characters, if fed in through an external text-file.

I’ve updated my script again. In general, it’s not good for any ‘program’ to have too many dependencies, and the previous version of this script depended on ‘tr’, ‘wc’, ‘sed’, and ‘gawk’, as well as on ‘Inkscape’. While this worked fine on my own computer, it doesn’t serve my potential readers well, who may not want to have all that installed, just to use my script. And so by now, I’ve removed the dependency on ‘gawk’, because what it did, ‘sed’ can do as well.
