Hello,

This is expected behavior when exporting a report book to a TIFF file.

The reason for this is that all pages in the TIFF file must have the same size, while the report book allows having reports with different page sizes.

As a workaround, you may try exporting the reports in the book individually. In the exportBegin(e,args) report viewer event, the args parameter will have the currently exported to format. You may apply the custom export only for the TIFF export format by hooking to this event similar to the example from the Replace report on export in the Html5 Viewer KB article.

Hello,

Downloading TIFF format of the report doesn't work on Linux Dockers. Is this expected?

Below is the link to article where it says it is not supported (highlighted). "TIFF is not supported by the library libgdiplus. For that reason, the TIFF Image export doesn't work on Linux and Mac platforms."

Is there a workaround?

Thanks, Raj.

Hello Raj,

I am afraid there is no workaround for this problem since it is a limitation of the libgdiplus library itself. We will be migrating to the SkiaSharp library soon and it is possible that this might allow TIF exporting, however, I cannot guarantee it yet as we are still in the process of migrating. The article will be updated if there is a change on this.

Thank you for your understanding.
