Having read the thread on images, it looks like there is a lot of thought and effort being put into adding images to Archi and ensuring compatibility with plugins like jArchi.
Having the ability to add images to archimate elements, groups, notes and stickies and also manage the image dimensions through jArchi would be immensely helpful.
I have recently been playing with the jArchi script to generate a single page HTML as a way to generate interactive documentation. The use of markdown embedded in the model for documentation is a great idea. However, due to limiting factors in jArchi I tried a different approach; adapting the standard Jasper report to perform some regex substitution and render basic markdown within PDF reports.
Being able to automate inclusion of images in stickies/notes from jArchi script and produce documentation from embedded markdown would be a game changer for me.
Keep up the great work!
