Calling offset method when rectangle is empty.

Hello mindfusion team!

I just wanted to know if there is possibility of avoiding empty rectangles when calling method Rect.Offset() in SvgExporter.Export()? I get the following exception when all diagram items don't have empty bounds and don't have NaN height or width.
Code
Select All
2023-03-28 11:05:29.8787|Fatal|Unexpected error occurred. | System.InvalidOperationException: Cannot call this method on the Empty Rect.

Hi,

SvgExporter calls that only on GlyphRun boundaries and we can't think of why would be empty. Please post exact text and font with which you are seeing the error.

Nevermind. It turned out the problem was with text with "-" symbol and whitespaces around it. For example, "text - text" caused this error during exporting, but it seems you've fixed it. Well done Wink
