THotPDF.LocalFileMappingWindowSize

Sets the target byte range covered by each cached read-only view

Declaration

property LocalFileMappingWindowSize: Integer;

Default

16777216 bytes, or 16 MiB

Behavior

• The effective size is aligned to the operating-system allocation granularity
• With adaptive geometry enabled, this value and LocalFileMappingCacheWindows define a fixed total mapped-byte limit that can be redistributed across active windows
• Cross-window reads are copied in bounded segments
• Values below 64 KiB raise ERangeError
