The Print Preview Components v5.0 has been released. This is an upgrade release.

• [feature] Display rendering for PrintPreview, ThumbnailPreview, and PaperPreview controls are highly optimized.
• [feature] Before this version, the PrintPreview control was keeping only one single page on memory. Now, you can set the number of cached pages using the new CacheSize property.
• [change] As of now, when there are more pages than cache size, the PrintPreview control uses only a temporary file (very optimum). Because of that UseTempFile property is obselete and has been removed.
• [feature] Besides editing a page, you can now insert new or replace an existing page. Deleting and reordering of pages is also possble. The methods for these actions are BeginReplace, EndReplace, BeginInsert, EndInsert, Delete, Exchange, and Move.
• [feature] To know at each time which page owns the PrentPreview canvas, the new CanvasPageNo property is added.
• [feature] To make conversion of units a bit easier, BoundsFrom, RectFrom, PointFrom, XFrom, and YFrom methods are added.
• [change] Because for adding a new printer form the user must have the required priviledge on Windows, the control no more automatically add or remove forms. As the result, AutoFormName property and OnAutoCustomForm are obsolete and removed. Instead, use IsDummyFormName property to know the FormName property contains an actual form name or a temporary name.
