0 |
None |
No fitting. Use Position and ZoomPercent if they have valid values.

1 |
Fit |
Show the whole page in the view. If the page is smaller, do not zoom in.
|
2 |
FitAlways |
Show the whole page in the view. If the page is smaller, zoom in to fit.
|
3 |
FitWidth |
Fit the view so the whole width of the page is visible.
|
4 |
FitHeight |
Fit the view so the whole height of the page is visible.

DocumentPageFitType is used as the value for DocumentLinkTarget.PageFitType.
