Problem with SetColumnWidthPixel()

[MarkSheehan]

We have recently upgraded from Aspose v4.3 to v6.0.1 and are encountering an error that we did not previously receive. We are attempting to call Cells.SetColumnWidthPixel(5, 2400). While the documentation on-line here does not indicate a limit to the number of pixels one can set with this function, it appears that Aspose.Cells subsequently makes an internal call to SetColumnWidth() function and is attempting to pass a width parameter that is outside the 0-255 range for that function's parameter.

How is the SetColumnWidth() width parameter determined based on a call to SetColumnWidthPixel()? Since 255 is the limit for the SetColumnWidth() function's width parameter, what is the effective limit of the SetColumnWidthPixel() function's width parameter?

I see a similar issue with identical stack track was reported here with SSRS through .NET:

Hi,

Well, we follow MS Excel standards and depends upon the limitation that MS Excel does put forth. In MS Excel how could you do that. You may have a column with a maximum value i.e 1790 (in pixel), you cannot have more than that value for a column. So, consequently you can set Cells.SetColumnWidthPixel(5, 1790) --> 1790 refers to 255 in points. You may check this in MS Excel.

Sample code:

Workbook wb = new Workbook();

Worksheet ws = wb.Worksheets[“Sheet1”];

Cells cells = ws.Cells;

cells.SetColumnWidthPixel(0, 1790); //This works. i.e. 1790 pixels = 255 points

// cells.SetColumnWidthPixel(0, 1791); //This will not work. --You can check.

wb.Save(“e:\test2\columnwidthset.xlsx”);

If you could set more than that, create a template file in Ms Excel and post it here, we will check it soon.

Also, check the document for reference:
