How can I calculate Text Note height without making a commit for performance

[WorldDue]

Hello,

In case of inserting many Text notes, I want to commit once without making sub Transactions or such which is costly to performance.

So how can I pre-calculate the text height in C#

Can I use the Graphics.MeasureString() function? If so how can I set the size and width of the TextNoteType in C# Graphics module, and also what about the units used in both the API and the Graphics c# class..

Thanks.

Well, apparently querying the bounding box requires a regeneration; that is a lot less heavy than a sub-transaction or transaction:

Here is a sample showing how to use MeasureText:

I hope that is useful.
