Documents often have wide margins for printing. They are annoying when reading the document on the screen, because they use up screen space and can cause inconvenient scrolling.
With DocView you can hide these margins by selecting a slice of pages to display. A slice is a rectangle within the page area; once you specify a slice in DocView, it applies to whichever page you look at.
To specify the slice numerically, type s s
doc-view-set-slice); then enter the top left pixel position
and the slice’s width and height.
A more convenient graphical way to specify the slice is with s
doc-view-set-slice-using-mouse), where you use the mouse to
select the slice. Simply press and hold the left mouse button at the
upper-left corner of the region you want to have in the slice, then
move the mouse pointer to the lower-right corner and release the
The most convenient way is to set the optimal slice by using
BoundingBox information automatically determined from the document by
typing s b (
To cancel the selected slice, type s r
doc-view-reset-slice). Then DocView shows the entire page
including its entire margins.
