Public API Changes
Support of Presentation to animated GIF export
Support of Presentation to animated GIF export has been added. Using this new functionality it is now possible to export Presentation into animated GIF with slides changes, including animated transitions:
using namespace Aspose::Slides;
using namespace Aspose::Slides::Export;
auto presentation = System::MakeObject<Presentation>(u"pres.pptx");
auto gifOptions = System::MakeObject<GifOptions>();
// the size of the resulted GIF
gifOptions->set_FrameSize(System::Drawing::Size(180, 135));
// how long each slide will be showed until it will be changed to the next one
gifOptions->set_DefaultDelay(2500);
// increase FPS to better transition animation quality
gifOptions->set_TransitionFps(12);
presentation->Save(u"pres.gif", SaveFormat::Gif, gifOptions);
Export result:
IChartDataWorkbook::CalculateFormulas() and ChartDataWorkbook::CalculateFormulas() methods have been added
IChartDataWorkbook::CalulateFormulas() and ChartDataWorkbook::CalulateFormulas() methods have been added. These methods provide the functionality of an explicit formulas calculation within the workbook. The calculation performers in two steps:
- check for unsupported formulas within the entire workbook. If found, the CellUnsupportedDataException will be thrown. Values will not be updated.
- if the unsupported formulas check was passed, formulas will be calculated for the workbook, and cells values will be updated.
Cell’s formula reset on setting the value (and vice versa) has been removed.
