Reports caching

The reports and it's data can be cached both in memory (for speed increasing) and in file on the disk (for saving RAM recourses). There are several types of caching in FastReport:

• TfrxReport.EngineOptions.UseFileCache - if the property is installed in True, than the whole text and objects of built report are saved in temporary file on disk, at that TfrxReport.EngineOptions.MaxMemoSize indicates how many MB are meant for the template in RAM.

• TfrxReport.PreviewOptions.PagesInCache - the number of pages which can be kept in cache memory greatly increases preview speed, but spends much memory (especially when there are pictures in a template).

• TfrxReport.PreviewOptions.PictureCacheInFile - if the property is on, than all the pictures of built report are saved in temporary file on a disk, that greatly reduces memory use in reports with a large amount of pictures, but it reduces the speed.
