THotPDF.LoadedFontDecoderCacheMaxBytes

Defines the maximum estimated memory retained by parsed font decoders for the current loaded document

Declaration

property LoadedFontDecoderCacheMaxBytes: Int64
  read GetLoadedFontDecoderCacheMaxBytes
  write SetLoadedFontDecoderCacheMaxBytes;

Behaviour

• The default budget is 33554432 bytes and the cache also retains at most 128 entries
• Reducing the budget evicts least recently used entries immediately
• Setting the budget to zero disables retention while decoder requests continue to work
• Negative values are normalised to zero
• Loading another document clears retained decoders and resets statistics
