Does anyone know of a free Windows software for drawing circuit diagrams with the following features? It does not have to be a dedicated prog for schematics and I'm *not* talking about a CAD program with schematic capture, simulation and pcb layout. It can be a painting program with these features.
- Have a symbols library from which symbols can be selected with a mouse click and placed anywhere on the work space with another click - like brushes in a painting program..
- Being bundled with an extensive library of electronic symbols would be a bonus, but this is not essential as long as user-created symbols can be added easily.
- Can save directly in popular image formats like bmp, png, jpeg, gif.
