HMI Graphics Creator

Dear Friends,

I am trying to create some graphics for an HMI screen. Does anybody have an idea how and where I can find or make some nice graphics for an HMI screen.

Any suggestion would be highly appreciated.

Thank You,

I like to make graphics in a vector format. For this one of the best programs ot use is inkscape.

Even if your HMI only accepts bitmaps, it really helps to work in vector format for the originals.

For manipulating bitmap images, Paint.net is the way to go:
