Hi,

I just started using your library to move my cursor.

Is it possible that it ignores negative values in moveBy?

In other words, I can only move the cursor into one direction.

I did some research, and traced this to a bug in an old (1.6) version of xcb-proto [1]. The coordinates were declared incorrectly as Word16, instead of Int16 as they should have been. It's been fixed in xcb-proto since 1.7.

Okay, I've released a new version of Robot (1.0.1.1), that should fix this bug. Niklas: can you try it out please? Also, it turns out taking a screenshot is much easier than I thought. A single call to getImage returns a list of bytes, which happens to match exactly the internal structure used by JuicyPixels. I'll look deeper into this when I get the time.
