Document Processing

When there are split panes in a workbook, the topLeftCell property can be omitted. In this case, the format provider throws NullReferenceException.

CMYK color may be set using SCN, scn, K and k operators.

Provide the ability to work with images in headers/footers of a worksheet. Note that large images put in headers are visualized as watermarks on printing/exporting to PDF.

The issue is reproducible only in a specific setup with a specific document. It is related to the calculations of the line spacing when the table row should be split between two pages.

Workaround: Change the line spacing:
foreach (var paragraph in this.document.EnumerateChildrenOfType<Paragraph>())
{
paragraph.Properties.LineSpacingType.LocalValue = HeightType.Exact;
paragraph.Properties.LineSpacing.LocalValue = 15;
}

Applying LockAspectRatio to an image is not respected after opening the document in MS Word - the LockAspectRatio checkbox in the is not checked. An additional XML element (cNvGraphicFramePr) should be added so the UI can respect it.
