Hi,
this is the documentation about layout parameters
Code:
/**
* set layout parameters.
* @param verts applied duals flag for vertical screen
* @param horzs applied duals flag for landscape screen<br/>
* Element which set to true mean this cell treat as dual page, otherwise treat as single page.<br/>
* For example, book has a cover(first page treat as single) just codes:<br/>
* verts = null;<br/>
* horzs = new boolean[1];<br/>
* horzs[1] = false;<br/>
* Pages, those out of array bound:<br/>
* in vertical screen: treat as single page(false).<br/>
* in landscape screen: treat as dual page(true).<br/>
*/
To center the pdf vertically you have to set the last parameter (
page_align_top ) to
false.
