Aspose cell: ToTiff function Issues

Hi Team,


I am using below code to generate tiff image from Excel file.
I am leveraging Page Break and Page titles in excel.

Workbook excelDocument = new Workbook(excelStream);
LicenseManagement.SetAsposeCellLicense();
Worksheet sheet = excelDocument.Worksheets[excelDocument.Worksheets.ActiveSheetIndex];
Aspose.Cells.Rendering.ImageOrPrintOptions imageAndPrintOptions = new Aspose.Cells.Rendering.ImageOrPrintOptions();

imageAndPrintOptions.TiffCompression = Aspose.Cells.Rendering.TiffCompression.CompressionLZW;
imageAndPrintOptions.IsCellAutoFit = true;
imageAndPrintOptions.ImageFormat = System.Drawing.Imaging.ImageFormat.Tiff;
imageAndPrintOptions.PrintingPage = Aspose.Cells.PrintingPageType.Default;
Aspose.Cells.Rendering.SheetRender sr = new Aspose.Cells.Rendering.SheetRender(sheet, imageAndPrintOptions);
MemoryStream fs = new MemoryStream();
sr.ToTiff(fs);// You can save to file system here

Below issues are found in Tiff image generation.
1. Mismatch in number of columns in generated page. It should be exactly as Print Preview of excel.
2. Cell with orientation not reflected in output.
3 Lost of data: When we set Print title : Columns to Repeat in source excel. Last column data is lost.
4. Extra column is displayed if we set columns to repeat in source excel.

You can use above code with attached excel documents to reproduce the issues.
Feel free to ask any details.


Thanks and Regards,
Nakul

Hi Team,

Good job on this one and a special thanks goes to Nakul. Thank you very much Nakul.

I was facing the same issue (CELLSNET-41190) as Nakul and I'm glad to see that it is fixed in Aspose.Cells for .NET 7.4.1 (and 7.4.2).

Unfortunately, I've noticed that even if Text orientation is now fixed, the text alignment is not working.
So if the text orientation is "angled" *AND* alignment is set to Middle Align (vertical) and Center (horizontal),
the resulting image does not respect the alignment.

I'm using SheetRender ToImage
