Multiple CSS classes on an element are not correctly resolved when converted to inline styles.

Before:

.TelerikNormal {font-family: Calibri;font-size: 14.6666666666667px;margin-top: 0px;margin-bottom: 0px;line-height: 100%;color: #000000;}
.TelerikHeading3 {font-family: Calibri Light;font-size: 22.6666666666667px;}
<p class="TelerikNormal TelerikHeading3"><span>Test</span></p>

Due to order priority, the TelerikHeading3 values override the TelerikNormal values. The font-size becomes 22.6666666666667px.

Convert:

provider.ExportSettings.StylesExportMode = StylesExportMode.Inline;
After:
<p style="font-family: Calibri;font-size: 14.6666666666667px;margin-top: 0px;margin-bottom: 0px;line-height: 100%;color: #000000;"><span>Test</span></p>
ResultTelerikHeading3 and its properties are ignored and not applied during the conversion to inline styles. The font-size is now 14.6666666666667px.

Hi, we are facing the below error when trying to convert a Docx file type to PDF type using RadFlowDocument in C# (.NET core 6.0). Please can you help with this issue as soon as possible?

Error message: "Negative height, if converting in Net Standard try registering a smaller font (Parameter 'height: -17.908799999999985')"

 

C# code snippet for reference:

  BinaryFormatProviderBase<RadFlowDocument> provider;
  RadFlowDocument document;

  using (var output = new MemoryStream())
  {
      provider.Export(document, output)

  }

When you have indented and justified text, it is wrongly exported to PDF:

			<w:pPr>
				<w:spacing w:after="0" w:line="360" w:lineRule="auto"/>
