Ask HN: How do drawing programs work?

2 pointsby icimi13 lat temu2 comments

I have a decent idea how the web works. From the DOM to the database, I have a fairly solid understanding of each. Now I want to learn something new.

Drawing programs. How do they work? How does MS Paint work? How does Photoshop work? How does Autocad work?

What kind of architecture do these systems have? What kind of systems and subsystems is needed for this to work? How different are drawing programs from MVC and network architecture?

Can anyone point me to some good resources?

http://pinta-project.com/ This is open source, with a little bit of hacking you can get to study the source code of one of the most-used drawing/painting applications.

Is this based on some parts of GIMP?

I haven't heard much good news coming out of the GIMP world.
