My requirement is to write data to excel Header & Footer section which is accomplished using the following code. HSSFHeader header=this.sheet.getHeader(); header.setCenter("XXX"); header.setLeft("YYY"); header.setRight(HSSFHeader.page()); HSSFFooter footer=this.sheet.getFooter(); footer.setCenter("XXX"); footer.setLeft("YYY"); footer.setRight("ZZZ"); My question is how can I write an image (for eg:a logo)to the header/footer? setCenter() setLeft() setRight() alll expects String Please help me to resolve the issue.

Created Unassigned: IPatternFormatting.FillPattern should be of type FillPattern, not short [13973]
Looks like I missed at least once place when I revamped the API a while back, fixing all of the 'short' and 'int' properties to be the appropriate enum types instead.
I just noticed that I missed IPatternFormatting.FillPattern.

Created Unassigned: XSSFPatternFormatting does not have a way to set an XSSFColor [13974]
This API may be missing because it's not possible, I don't know...
I'm hoping it's just something that's been overlooked :)
For now I can just use the IndexedColors, so this isn't a high priority...

I gave a quick look at the code last night and I *suspect* that I could probably clone the logic from XSSFCellStyle's `SetFillForegroundColor(XSSFColor)` over to XSSFPatternFormatting, but I am just guessing :)

Commented Unassigned: Incorrect value of calculation with INT operator [13924]
In the following example I try to calculate different formulas, but the results of calculation are sometimes incorrects (and really understandables) :
```
var workbook = new HSSFWorkbook();
var sheet = workbook.CreateSheet();
var row = sheet.CreateRow(0);
var cell = row.CreateCell(0);
var evaluator = workbook.GetCreationHelper().CreateFormulaEvaluator();
// should be 6.0 => OK
cell.SetCellFormula("INT(6.99)");
var cellValue = evaluator.Evaluate(cell);
var result = cellValue.NumberValue;
// should be 6.0 => KO : 7.0 is returned
var cell1 = row.CreateCell(1);
cell1.SetCellFormula("INT(6.991)");
var cellValue1 = evaluator.Evaluate(cell1);
var result1 = cellValue1.NumberValue;
// should be 6.0 => OK
var cell2 = row.CreateCell(2);
cell2.SetCellFormula("INT(6.9900000000000005)");
var cellValue2 = evaluator.Evaluate(cell2);
var result2 = cellValue2.NumberValue;

cell3.SetCellFormula("INT(6.9900000000000007)");

New Post: How To Convert Shape to Image
I have requirement to get all images including shapes from excel (.xls and .xlsx) and save it in directory, I've trying using HSSFWorkbook.GetAllPictures(), it does get all images but not the shapes, so i find another method and i found GetSheetAt(0).DrawingPatriarch.
here snippet of my code :
Question is, how to convert HSSFSimpleShape data to Image? Is that Possible? Is there anything I miss?
Hope Someone can help, Thanks
here snippet of my code :
var dr = workbook.GetSheetAt(sht).DrawingPatriarch;
HSSFPatriarch pat = (HSSFPatriarch)dr;
var shape = pat.Children;
int i = 0;
foreach (var s in shape)
{
string patType = s.GetType().ToString();
switch (patType)
{
case "NPOI.HSSF.UserModel.HSSFSimpleShape":
{
var simpleshape = (HSSFSimpleShape)s;
/*Save Shape*/
break;
}
case "NPOI.HSSF.UserModel.HSSFPicture":
{
var pic = (HSSFPicture)s;
byte[] data = pic.PictureData.Data;
/*Code to Save Image From Byte[]*/
break;
}
default: break;
}
}Question is, how to convert HSSFSimpleShape data to Image? Is that Possible? Is there anything I miss?
Hope Someone can help, Thanks

This is controlled in the source code here:
main\SS\Formula\Functions\Int.cs
public class Int : OneArg
{
public override double Evaluate(double d)
{
if (d > 0)
return Math.Round(d - 0.49);
else
return Math.Round(d - 0.5);
}
}
Should be Math.Floor(d) instead of Round I think.

Thanks a lot !
This code corrects the problem
```
public class Int : OneArg
{
public override double Evaluate(double d)
{
return Math.Floor(d);
}
}
```
Both Excel and Math.Floor give the same result
```
- INT(-2) => -2
- INT(-1,9) => -2
- INT(-2,1) => -3
- INT(6,99) => 6
- INT(6,991) => 6
- INT(6,9900000000000005) => 6
- INT(6,9900000000000007) => 6
- Math.Floor(-2) => -2
- Math.Floor(-1.9) => -2
- Math.Floor(-2.1) => -3
- Math.Floor(6.99) => 6
- Math.Floor(6.991) => 6
- Math.Floor(6.9900000000000005) => 6
- Math.Floor(6.9900000000000007) => 6
