Hello Aspose, we noticed a decrease in memory usage with Workbook.getSettings().setMemorySetting(MemorySetting.MEMORY_PREFERENCE) during Excel document creation (aspose docs: Optimizing Memory Usage while Working with Big Files having Large Datasets|Documentation (aspose.com) . Is there a comparable memory setting for optimizing memory usage in Presentation or Slides objects?
Regarding Aspose.Slides, by default memory optimization is on when you open any presentation or even large presentation using Presentation class. You may set options under LoadOptions when reading the large file accordingly. See the documents with examples for your reference.
