About clearing buffers

Your buffer is effectively your pasteboard (otherwise referred to as ‘clipboard’.)

If you have been copying large raster areas (see copying a raster area) your computer’s resources (i.e. your RAM) may become bloated which will in-turn prevail less than optimum PC performance.

The Clear Buffers tool is a useful feature in these circumstances. When executed you will permanently delete your  pasteboard therefore freeing some of your computer’s resources.

How to clear buffers

Select Raster Edit Menu > Clear Buffers.

Clear Buffers clears the Pasteboard.

Please note: You cannot undo Clear Buffers.
