Build 3.5.0.123 of xlsgen exposes column widths in pixels, through a new property called WidthInPixels in the IXlsWorksheetColumns interface.

So far the width exposed the metrics used by Excel for column widths in XLS and XLSX files (and their variants). The metrics were not pixels, inches or anything of this.

A few months ago, we introduced pixel-based API in the object model for working with many objects such as charts, text boxes and so on.

This build exposes column widths so it is possible to get or set the width in pixels.
