plt

basic hpgl plt editor written in python & tkinter

The generated .plt files work on the engraver I have available, probably not standard hpgl code. That being said, it does open random plt files I found on the internet.

Fonts

True Type fonts can be used, it parses the fonts folder to find them. Some work, some don't, depending on how complex they are.

Visualize plot

You can use this menu option to visualize the path the plotter is going to take. You can hit ESC to cancel the simulation.

Pens

I implemented basic support for changing pens. The engraver I tested on doesn't support this option, but it should work. You select the lines you want to be a different pen, and then use the menu to change them. Everything is drawn in pen 1 by default.

You can’t perform that action at this time.
