TIFF (Black and White) (B&W)(*.tif)

Exports as a black and white TIFF (Tagged Image File Format) image.

TIFF is a container format including images and data within a single file with header files describing the internal properties such as the size, definition and applied compression.

When you use this command, the extents of the saved image are not necessarily those of the view you see on screen. 

What is saved is the extents of your last zoom. In the case of raster data, the image dimensions are forced to match the aspect ratio of the current view.

Select File > Export > Export to File and select Tiff (Black and White).
