PDF Export speed

Stoyan,

Exporting PDF is taking a lot longer than it used to (up to almost 30 seconds) and is creating a large file than expected. What can I do to speed up this process and help the file become smaller?

I think it used to work faster in older versions. Am I correct?

Thank you.

There was an entirely new PdfExporter implementation for the 2.0 release, if by older versions you mean 1.x. We haven't changed the exporter code much since then. Perhaps you have recently set some appearance properties that might take longer to process when exporting?

Stoyan,

Through some more testing, I found out that the speed is very sensitive to length of the text in each node.

More specifically, "vbNewLine" and " " that are part of the text in the node.

If I replace all " " with any character to remove spaces but keep the length same for testing, the pdf is created about 1/2 to 1/3 of the time.

Is this expected or is there something I can do to optimize this?

Thanks.

The last build we sent you has some new code for detecting the character encoding that should be applied for each PdfGraphics.DrawString call. Perhaps that causes the delay if you noticed it with the latest version.

Is there anyway to override or set the encoding to a specific one to speed this process?

Thank you.

There isn't. We'll try to optimize this for the official release, or will add some property to turn the detection off.

Try the version from the PM page. PdfExporter should work faster now with lots of text.
