In principle, the blend function B (Cb , Cs ) is used in the compositing formula to customize the blending operation in Adobe transparency imaging model. The blending mode may define any function which yields another result color from the backdrop and source colors. This will allow overlaying objects on each other forming a transparency stack.

Support for the Blend Mode parameter of the external graphic state should be implemented.

Currently adding an Image content element with ImageSource instantiated with a PNG file format leads to NotSupportedException: 'Can not export other than Jpeg and Jpeg2000 and ImageQuality different than High', when exporting the document.

Support for adding PNG images and exporting to PDF should be implemented for PdfProcessing for .NET Standard scenario.

Support for exporting WMF (Windows Metafile) and EMF (Enhanced Metafile) images should be implemented.

Workaround: Convert the WMF images to PNG before exporting:
ImageSource imageSource = new ImageSource(new MemoryStream(this.ConvertWmfImageToPng(stream)));
document.Pages.AddPage().Content.AddImage(imageSource);
...
private byte[] ConvertWmfImageToPng(Stream wmfImageStream)
{
    byte[] pngBytes;
 
    using (MemoryStream pngImageStream = new MemoryStream())
    {
        System.Drawing.Image imageDrawing = System.Drawing.Image.FromStream(wmfImageStream);
        imageDrawing.Save(pngImageStream, System.Drawing.Imaging.ImageFormat.Png);
        pngBytes = pngImageStream.ToArray();
    }
 
    return pngBytes;
}

Release LIB 2019.2.701 (07/01/2019)
By the PDF format specification, CIDToGIDMap is optional. The default value is Identity. However when exporting CID Font with missing CIDToGIDMap property the analyzing tool causes the following warning message:

"PDF/A requires that a Type 2 CIDFont has a stream mapping from CIDs to glyph indices or the name Identity as its value."

When merging files the documents might have the same fonts embedded. Then the PdfProcessing should use only one of the fonts and skip embedding the second font in the resulting document.

Release LIB 2019.2.624 (06/24/2019)

When there is long text that is out of the used cell range area, this text should be included in page splitting calculations.

Also, when a cell has text that overflows its width, the text is again clipped by the cell boundaries and is not visible in the exported PDF. In a similar case Excel exports the surrounding cells to ensure that the content is visible.

Workaround: Extend the used cell range to include all the cells which the text content spans.

By specification, the InteractiveForm fields can have the same name if they are descendants of a common ancestor. Such fields are different representations of the same underlying field; they should differ only in properties that specify their visual appearance. When such a document is imported an ArgumentException: 'An item with the same key has already been added.' is thrown.

A free text annotation displays text directly on the page. Unlike an ordinary text annotation, a free text annotation has no open or closed state; instead of being displayed in a pop-up window, the text is always visible.

By specification, the document AcroForm contains fields with no parents. However, some documents may have child fields in the AcroForm. This leads to ArgumentException when importing the child and parent fields - 'An item with the same key has already been added.' since the child field is added twice.
