C# 클래스 Bloom.BookThumbNailer

This class is a place to gather the methods that have to do with making thumbnails of pages of books. Three of the methods were previously methods of Book itself, but the fourth (MakeThumbnailOfCover) needed to do too much UI stuff to belong in a model class, so it seemed worth pulling all this out to a new class. In live code there is typically only one instance of this created by the ApplicationServer. In test code they may be created as needed; nothing requires this to be a singleton. Indeed, it could be a static class except that it requires the HtmlThumbNailer.

BookThumbNailer ( HtmlThumbNailer thumbNailer ) : System
GetThumbNailOfBookCover ( Book book, HtmlThumbNailer thumbnailOptions, Action callback, Action errorCallback, bool async ) : void
GetThumbnailForPage ( Book book, IPage page, bool isLandscape ) : Image	Currently used by the image server to get thumbnails that are used in the add page dialog. Since this dialog can show an enlarged version of the page, we generate these at a higher resolution than usual. Also, to make more realistic views of template pages we insert fake text wherever there is an empty edit block. The result is cached for possible future use so the caller should not dispose of it.
MakeThumbnailOfCover ( Book book, Control invokeTarget ) : void
MakeThumbnailOfCover ( Book book, int height, Control invokeTarget ) : void
RebuildThumbNailAsync ( Book book, HtmlThumbNailer thumbnailOptions, Image>.Action callback, Exception>.Action errorCallback ) : void	Will call either 'callback' or 'errorCallback' UNLESS the thumbnail is readonly, in which case it will do neither.
RebuildThumbNailNow ( Book book, HtmlThumbNailer thumbnailOptions ) : void	Will make a new thumbnail (or throw) UNLESS the thumbnail is readonly, in which case it will do nothing.
