Possible bug in transparency of column chart - Aspose.Cells .Net

Aspose.Cells Product Family
1

Please see attached workbook column_test.xlsx


Using Aspose.Cells .NET 7.5.0.5 on this workbook causes the transparency to become deeper.

The code is very simple (just load into Aspose and save out again):

Workbook columnTest = new Workbook(“column_test.xlsx”);

columnTest.Save(“output.xlsx”);

If you check the red of the column chart you will see that it becomes deeper - yet underneath if I check transparency then it is still set at 50% - Aspose seems to somehow be messing up transparency?

See attached image showing comparison of before on the left and after on the right. Why does the transparency of the chart get messed up by using Aspose here? Is there a workaround?
