MiniCap

"Cmmandline screenshot capure; by name, pid, hwnd, interactively, etc."
By SoftCns Editor: MiniCap is a minimal screenshot capture app, with great commandline support, including the ability to launch (and then terminate) apps, capture windows by pid, handle, program name. And a nice interactive mode including scrolling capture. Tons of options for saving files in different formats with automatic naming and versioning.
