The Zoom functions provide a means to modify the magnification level of the image. Zooming in to an image is useful for pixel level image modifications and zooming out can be handy for working with broad effects.
Two of the common zoom commands are Zoom In, and Zoom Out. Each time Zoom In is used, the zoom level is increased by a factor of 100% and each time Zoom Out is used, the zoom factor is decreased. When zooming out, the factor will slowly decrease and there is a minimum zoom level of 6% whereas the maximum zoom level is 1600%.
Default Keyboard Shortcuts: = zooms in, - zooms out, and 1 resets the zoom level to 1:1.
