View mode
There are a few view modes which can be adjusted to provide an optimal presentation such as layout, fit, or reflow.
Page fit & default zoom mode on iOS
PDFViewCtrl's page view mode controls the default zoom level of pages and documents. New documents will automatically open at the zoom level specified by the mode.
Page view modes
PDFViewCtrl supports the following page view modes:
| Page view mode | Description | Screenshot-portrait | Screenshot-landscape |
|---|---|---|---|
e_trn_fit_page | The zoom is set so that the entire page is visible without scrolling. |  |  |
e_trn_fit_width | The zoom is set so that the page's width matches the viewer's width. | |  |
e_trn_fit_height | The zoom is set so that the page's height matches the viewer's height. |  | |
e_trn_zoom | The viewer's zoom is not adjusted based on the page. |  |  |
Set the default page fit mode
You can set a default page fit mode in your PDFViewCtrl by using setPageRefViewMode(_:).
Set the page fit mode dynamically
If you want to dynamically change the page fit mode, use setPageViewMode(_:). Note that when the user flips the page, the page view mode will be automatically reset to the default mode set by setPageRefViewMode.
