This sets the zoom level. If $zoom is 1, it means no zoom. If
|
|
it's smaller than 1, it means zoom in. If it's bigger than 1,
|
|
it means zoom out. For example, $zoom 1 will be 1:1 pixel for
|
|
pixel. $zoom 2 will be 2:1 (that is 2x2 photo pixels will
|
|
display as 1 on-screen pixel) which is a zoom out. 4:1 will
|
|
be 4x4 photo pixels as 1 screen pixel, and so on. The $zoom
|
|
parameter must be greater than 0. It is suggested to stick
|
|
to powers of 2. (1, 2, 4, 8, 16, 32, etc.).

ensure no pixels within the frame are left unfilled.
