A simple Win32 program that displays a window of a given colour (by default, white)
When taking screenshots in Windows, it usually suffices to press Alt+PrtScn. However, if capturing multiple overlapping windows, the icons and wallpaper on the desktop can intrude. The purpose of this program is to provide a blank background that screenshots can be taken against without having to rearrange one's desktop to do so.
If run from the command-line, it will accept a HTML-style RGB hex triplet of the form #rrggbb as an argument. If run from Explorer, it will present a standard colour picker.
Clicking on the backdrop window with the left mouse button or pressing ESC will close it.
This was thrown together in a hurry. The command-line parser is particularly egregious. It does the job but is not very robust.
Built with MingW32.
