Hi everybody!

PDFsharp and MigraDoc 1.50.4000-beta3b are now available via NuGet.

Further information can be found here:
http://pdfsharp.net/Preview_Information.ashx

Do not forget to select “Include Prerelease” when trying to get the packages using the NuGet Package Manager.

PDFsharp now supports reading PDF files with Object Streams (IRef and XRef streams). This works with many files, but some files may cause exceptions when you open them with PDFsharp. Please submit samples of files that cannot be opened with PDFsharp 1.50 beta 3.

Creating PDF files using the GDI+ or WPF builds of PDFsharp or MigraDoc should work well and stable. We fixed many bugs and we hope our bug fixes did not introduce new bugs.

New for beta 3:
  • Several bug fixes
  • Options that allow to either create smaller PDF files or to speed up PDF creation

The new PDF Core build and the Silverlight build are incomplete.

The complete source code for PDFsharp was released on CodePlex and SourceForge today.
https://pdfsharp.codeplex.com/releases/view/618773
The source for MigraDoc and the samples will follow soon. Source will also be available on GitHub.


You can follow PDFsharp on Twitter to get information about new releases.

New for beta 3a (December 9, 2015):
Bug: File not closed after call to PdfDocument.Save().
Bug: XPrivateFontCollection for GDI build sometimes caused exceptions.

New for beta 3b (December 15, 2015):
Bug: Exception when opening valid PDF files.

As of beta 3b, we have published the source code on GitHub:
https://github.com/empira/PDFsharp
https://github.com/empira/MigraDoc
You can also find it on CodePlex and SourceForge.

Is there an estimation of when will the 1.50 version become stable?
We are really looking forward to use a version with this bug fixed, but we'd rather not use a lib marked as beta on a production.

Hi, David!

As of today I cannot make an official statement about this.

IMHO 1.50 beta 3b is pretty stable - the stupid bugs that lead to 3a and 3b may make it look more immature than it is.
Support for IRef streams is a new feature and it is essential that many people test this feature with different PDF files and provide feedback.

There were no new issues with IRef streams since beta 2, so this new feature also seems to be pretty stable.
We use 1.50 beta in production code. It is far better than 1.32 stable.

@all: information about PDFsharp 1.50 beta 3b in first post.

Does the beta3b release include any table rendering speed enhancements beyond those in beta2?

I saw there were some links to patches hosted on http://www.pakeha_by.my-webs.org/ in earlier threads that claimed to improve the rendering performance many times - were those improvements included in the beta2 or beta3 builds?

Thanks!

None I am aware of.

No.

With PDFsharp 1.50 beta 2 (available on NuGet as a prerelease package), table rendering got much faster.

PDFsharp + MigraDoc WPF 1.32.2608:
Average: 24.443 seconds
MigraDoc-1.32-patched-release (WPF) from Pakeha:
Average: 9.114 seconds
PDFsharp + MigraDoc (WPF) 1.50.3638-beta:
Average: 16.114 seconds
PDFsharp + MigraDoc (WPF) 1.50.3915-beta2:
Average: 1.559 seconds

So maybe it is worth giving the new NuGet packages a try.

Bug report : PDFsharp/MigraDoc 1.503638 beta 3b

When the e.g text is written over rectangle which is filled with solid brush and RGB color 0,0,0 is used, the text is invisible. If you use value 1,1,1, the text is shown

We need code to replicate the issue.
A solution based on our Issue Submission Template would be great.
