Fields

Field Description

LOAD_AND_RELEASE The source will be locked only for a time of IPresentation constructor execution.
If IBlobManagementOptions.is_temporary_files_allowed is set to false, all BLOBs
will be loaded into memory. Otherwise, other means such a temporary files might be used.This behavior is slower than PresentationLockingBehavior.KEEP_LOCKED, and if it is possible to pass the
ownership of the source to IPresentation, it is recommended to use PresentationLockingBehavior.KEEP_LOCKED.

KEEP_LOCKED The source will be locked for a whole lifetime of IPresentation instance, until it will
be disposed.
IBlobManagementOptions.is_temporary_files_allowed is must be set to true for using
this behavior, otherwise exception will be thrown.This behavior is recommended, it is faster and consumes less memory than PresentationLockingBehavior.LOAD_AND_RELEASE.

Remarks

The source is the parameter passed to the IPresentation constructor. In the example below, the source is the “pres.pptx” file:

        For this example, the source ("pres.pptx" file) will be locked for a [`IPresentation`](/slides/python-net/aspose.slides/ipresentation) 
        instance lifetime, i.e. can't be changed or deleted by the other process.
