Other Information
Keyboard Limitations. Some keyboards may not respond to all available built-in keys used by CapSnapper. For example, on the Microsoft@ Multimedia keyboard, the Pause and ScrollLock keys are on the same key, and do not properly handle Ctrl or Shift, and the PrintScreen key requires that you turn FunctionLock off. So you may want to remap to available keys on your keyboard.
Shadowed Menus. Because shadowed menus are implemented using layered windows, the captured menu includes the shadow, with any underlying screen pixels. For best menu capturing, turn off menu shadows. Of course, you can add drop-shadows in Adobe Photoshop or your favorite image editing program.
The Alt key. When selecting a keystroke, the Alt key is not available because it causes any menus to close.
Remote Desktop Connection (RDC). Windows RDC may act strangely with CapSnapper. For example, if you are running CapSnapper on both the local and remote systems, the local system will receive the keystroke. If you want to use CapSnapper through RDC, be sure it is off on the local system. Additionally, RDC occasionally sends keystrokes that CapSnapper may interpret as PrintScreen or ScrollLock, causing spurious captures or entering Mouse Capture mode, so you may wish to assign different keys.
Alpha Channel. Image files must be rectangular, but captured windows need not be. When corners are rounded, or unusually-shaped windows are captured, or when multiple windows (or windows and menus) are captured, the "leftover area" will be filled with the background color. When saving as RGBA (Red-Blue-Green-Alpha) color format in either TIFF or PNG files, CapSnapper will also mark these leftover areas as transparent. Most browsers and other image viewing programs will properly display the current background behind these windows. Note that you should set a reasonable background color anyway, in case the image is used by a program that does not handle alpha channels properly.
