This is a custom script to extend Automatic1111 StableDiffusion WebUI, in order to generate useful SVG or PDF icons given by your prompts.

It tunes your prompts in that way to create suitable images to be vectorizied by the POTRACE command line tool. The resulting SVG or PDF file is stored next to your png files in output/samples (default).

• New: Added Visual Styles - RadioButtons provided by the script. Edit the script to extend of modify Stuff like Illustration, Tattoo, Anime etc, to save your time finding prompts on your own. If nothing matches, select "None - promp only" and have back full control.

• New: Linux and Mac support handling POTRACE for you

• Clone or download the txt2vectorgraphics.py file
• place it into your SD-installtion folder into "scripts"
• run your webui as usual
• HINT: Install Microsoft Powertoys for free, and enjoy in your file explorer SVG previews.

If you're running under WSL, Ubuntu or another Linux distro you will need to install potrace. Run sudo apt install potrace.

Run brew install potrace. Ensure potrace is in your PATH so that you could run in simply by calling from a command terminal.

At execution time, the script checks if your have

• already POTRACE in your PATH
• if not, it will download automatically the zip from POTRACE´s sourceforge site (win-x64), https://potrace.sourceforge.net/download/1.16/potrace-1.16.win64.zip
  and extracts only the executable into scripts folder in the scripts folder.

• Use short prompts, like "Einstein", "Happy Einstein" ...
• avoid "realistic" attributes
• Sampling Steps ~40 is my best experience (to reduce noise and avoid details)
• CFG Scale 10-12
• Dont restore faces
• use 512x512 if no special demand on ratio
• Batch count support (16)
• Mostly you want to make white parts opaque (see checkbox in the scripts ui)
• Same for clipping the content to SVG size

Version 0.3:

• Fix on Controlnet internal images
• Display SVGs in gallery!
