How to update Linked Picture


I write data to an existing excel-file which has linked pictures in it (see screenshots for what I mean).
I then want to export this linked picture as an image (as part of a group, but that does not matter here).
When the image is created the values in the linked picture are not updated.
Now my question:
Is there a function, that one can use to update the linked graphic? When I open the excel-file in the excel interface, the old values in the linked graphic are displayed for a short moment and are then automatically replaced. When I close the file (without changing anything else on my own), excel will ask me to save the file. So the excel interface updates this linked graphic and I now want to know how to do this in the code with aspose.

Thanks for your help


Thanks for the screenshot.

Linked pictures take time to be loaded in MS Excel application. Whereas Aspose.Cells is a library that only processes and parses file format data (source XML data of the file), so it fetches the relevant data from the source which is saved in the file when loading the file into object model.
