The ImageInline class in the WordsProcessing library has a Description available as a property of the Image property. The FloatingImage class also has an Image property but it is internal and its Description property is not available for users of the SpreadProcessing library.

Exporting specific documents with fields to PDF causes NullReferenceException.

When a format string of type: _ * # ##0_ ;_ * -# ##0_ ;_ * "-"??_ ;_ @_  is set through code and the culture settings of the machine are set so that the number grouping symbol is space, the resulting format string comes out incorrect on export: _,*,# ##0_,;_,*,-# ##0_,;_,*,"-"??_,;_,@_, 

This will happen every time the symbols in-between and after _ and * coincide with the number group separator.

After Excel introduced the dynamic array support, files produced with the older Excel versions have formulas that may be displayed with @ in some contexts. For example a file that had the following:

=SUM(IF(A1:A10=1, B1:B10, 0))

Will be displayed like so:

=SUM(IF(@A1:A10=1, B1:B10, 0))

This is done in order to preserve the behavior of the files created in older versions of Excel.

The files created by SpreadProcessing are also treated by Excel as if they are created by pre-dynamic array Excel. Please, introduce support for the new behavior.

At the moment the only data that can be passed to FloatingChartShape is a CellRange to be parsed to a chart. Some clients would like to use the IChartData implementations: NumericChartData and StringChartData. We need a FloatingChartShape constructors like this:

public FloatingChartShape(Worksheet worksheet, CellIndex cellIndex, IChartData values, IChartData categories)

And others if necessary.

The export method of the WorkbookFormatProviderBase does not use its timeout parameter.
