A shading dictionary specifies details of a particular gradient fill, including the
type of shading to be used, the geometry of the area to be shaded, and the geometry of the gradient fill. Various shading types are available, depending on the value of the dictionary’s ShadingType entry:

• Coons patch meshes (type 6) construct a shading from one or more color
  patches, each bounded by four cubic Bézier curves.

When importing a document with a missing "endobj" operator, an exception is thrown: InvalidCastException: 'Unable to cast object of type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfInt' to type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.IndirectObject'.'

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

Before:

<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:

After:
Result: TelerikHeading3 and its properties are ignored and not applied during the conversion to inline styles. The font-size is now 14.6666666666667px.

 

ArgumentOutOfRangeException is thrown when creating a CapPathRound for an SVG element.

InvalidCastException is thrown when importing a document with an annotation declared in the Fields collection.

InvalidCastException is thrown due to incorrectly parsed stream dictionary.

When importing an xlsx document with a comment that does not have an author, an exception is thrown "Sequence contains no matching element" Note that this is a different bug from the very similar SpreadProcessing: Exception "Sequence contains no matching element" thrown in files containing notes or comments (telerik.com)

When the worksheet contains fraction numbers with fractional parts > 0.5 and < 0.5 and both these numbers have fraction format applied, the number with fractional part < 0.5 will have incorrect whole part.

IndexOutOfRangeException is thrown due to wrongly processed image data.

Currently, the SkiaImageFormatProvider considers the RadFixedPage.Size when creating the image. If the RadFixedPage.CropBox is specified, the developer can control what rectangle of the page to be displayed/printed. However, it is not considered when exporting to an image. Improving the SkiaImageFormatProvider to respect the CropBox as well will give the opportunity to crop just a certain region of the PDF page and save it as an image.

Exporting a specific PDF file generates large amounts of ExtGState entries, which results in large file sizes.

When a document has a deleted text as part of track changes and there is a comment on the deletion, the document throws InvalidOperationException upon import.
