Interface PageSpan

All Superinterfaces:

ImageSpan, Span, Span1D

All Known Implementing Classes:

ScrollBlockManager.PageSpanBase

public interface PageSpan

extends ImageSpan, Span1D

A page span - contiguous piece of a permascroll consisting of pages of the same size - e.g.postscript or pdf file. These spans are rectangular regions of one or more pages.

ImageSpan.getImage should return the image of a page when a single page is in the span, calling getImage for a PageSpan of more than one page is currently undefined (!!), waiting for a decision between showing the first page, the first page in a graphical representation showing a stack of pages, some type of splicing of the pages or whatever. It is also possible that it will be decided that an IllegalArgumentException should be thrown in this case.
