NAME ^

Gtk2::Ex::Xor -- shared support for drawing with XOR

DESCRIPTION ^

This is support code shared by Gtk2::Ex::CrossHair and Gtk2::Ex::Lasso.

Both those add-ons draw using an "xor" onto the pixels in a widget (hence the dist name), using a value that flips between the widget background and the cross or lasso line colour. Drawing like this is fast and portable, though doing it as an add-on can potentially clash with what the widget does natively.
