I think I saw a similar question here a few years back, just just can't find it.

I would like to draw descriptions of messages like this:

enter image description here

From a plain-text input file which describes them.

Maybe something like:

  • start byte
  • start bit
  • length
  • text

Preferably cross-platform, but I will settle for Windows.

    Any particular requirements for the output (e.g. file format, image size, resolution/DPI, etc.)?

If you accept pseudo-graphic lines in text, then CudaText is a solution. It has plugin Draw Lines (install from Plugins/ Addon Manager) to draw such lines/frames in plain text. Here is example of frames:

│ 0 │     IE identifier       │
│    Length of IE             │
│          Data               │

Paint such lines by Shift+arrows while plugin is activated. Toggle single/double lines by F9.
