| == Image swapping == |
| |
| LO has two kind of swapout mechanisms: |
| |
| 1) Size based auto swapping: when the size of all graphic objects reaches a configurable limit (20 MB by default) |
| then some of the graphics are saved to the local file system and freed in the memory. |
| Configure: Tools -> Options -> Memory -> GraphicsCache -> Use for LibreOffice |
| |
| 2) Time based auto swapping: after an image is swapped in / loaded a timer starts and when the timer (1 min by default) |
| has a time out this image is swapped out ( sometimes this time out is ignored when the image is in use ). |
| Configure: Tools -> Options -> Memory -> GraphicsCache -> Remove from memory after |
| |
| Both swapping are done by GraphicObject and GraphicManager. |
