The Special About VPE - Dynamic Layout

Normal report generators and PDF libraries are usually treating text, images and other objects statically within a list.

The Dynamic Layout feature provides an incredible easy but powerful concept, to determine the positions and dimensions of objects (like text, bitmaps, etc.) in relation to their contents and in relation to other objects. Thus, the management of complex positional dependencies between objects becomes a piece of cake.

Besides the free positioning of objects, VPE is capable to compute the width and height of text and images in advance - without placing such objects into a document - so that your program can decide at runtime, how the layout of a document shall be arranged. For text objects the number of characters and the current settings for the font are considered when computing the dimensions. In addition word- and page breaks are computed.

As a result of such computations your program can decide dynamically, if for example some text shall be placed on the current page, or on the next page. Or you can move dynamically other objects dependent from the result, or change the font size to make a text fit into a given area. You can arrange the whole layout of a document dynamically.

You can even switch at any time to any page and insert additional objects. The Professional Edition also provides the option to insert or delete pages retroactively. No report generator can do that!
