Release R2 2022

Splitting a row leads to copying all rows below it. During that operation, the information for the row height is lost, when the previous row has a cell spanning on the split one, leading to a missing row in the exported document.

The issue is a regression introduced in R1 2021.

Workaround: Set PreferredWidth to the second cell.

 PdfFormatProvider: When Arial Narrow Bold fond is set in the document the font-weight is lost when converting to PDF.

 

Workaround:

var fontData = File.ReadAllBytes(@"C:\Downloads\arial-narrow\arialnb.ttf");
FontsRepository.RegisterFont(new System.Windows.Media.FontFamily("Arial Narrow"), FontStyles.Normal, FontWeights.Bold, fontData);

Currently, the text extraction is following the behavior (text distance) as exported with Adobe.

Provide a setting in TextFormatProvider in order to keep the original distance as in the PDF document.

Release R1 2022 SP1

When exporting PDF documents containing images different than Jpeg and Jpeg2000 the PdfProcessing is using by default the ImageSharp library in order to convert these images to Jpeg.

It seems there is an issue in the older version of the ImageSharp library: Saving a PNG as Jpeg only processes a part of the image on .NET 6.

Workaround: This issue seems to be fixed in the current version (2.0.0) of the ImageSharp library.

When a document containing a SignatureField is exported with the IsEncrypted property set to true, a not set UserPassword is required to open it, which makes it impossible to be opened.

Workaround: Exporting with AES256 encryption does not have this problem:

provider.ExportSettings = new PdfExportSettings
{
	IsEncrypted = true,
	EncryptionType = EncryptionType.AES256
};
