Grayscale
The Grayscale option converts all views of the current document to Grayscale, suitable for black and white image requirements. You may find this useful when sending images to a black and white printer, or for capturing black and white image files.
Grayscale is available in the toolbar, View menu, or right-click menu. The Grayscale option works as a toggle, and all previous colour settings will be restored when Grayscale is toggled off.
