1 Tools on top of VCL. Common dialogs, file and print dialogs, wizards, vcl filters, lots of helper code.
6 LO has two kind of swapout mechanisms:
8 1) Size based auto swapping: when the size of all graphic objects reaches a configurable limit (20 MB by default)
9 then some of the graphics are saved to the local file system and freed in the memory.
10 Configure: Tools -> Options -> Memory -> GraphicsCache -> Use for LibreOffice
12 2) Time based auto swapping: after an image is swapped in / loaded a timer starts and when the timer (1 min by default)
13 has a time out this image is swapped out ( sometimes this time out is ignored when the image is in use ).
14 Configure: Tools -> Options -> Memory -> GraphicsCache -> Remove from memory after
16 Both swapping are done by GraphicObject and GraphicManager.
