useSaveIncremental property
Whether to use incremental save. Default is true. Enabling incremental save can improve save speed and reduce memory usage, but may increase file size. If you need to generate a smaller file, set this option to false for a full save. This affects all save operations in CPDFReaderWidget, including manual and auto-save, such as saving, sharing, and saving on exit. Only supported on Android platform.
