Hi,

Aspose.Slides throws Stream was too long exception when attempting to load a large size files(3.5 GB).
i am using Aspose slides 16.12.1.0 in Win 7 64 bit SP1 core i7 3.40GHz with 16 GB RAM

Code:
----------
FileStream fis = new FileStream(InputFileName, FileMode.Open, FileAccess.Read);
Aspose.Slides.Presentation pres = new Presentation(fis); // throw Exception

Aspose.Slides.Export.PdfOptions opts = new Aspose.Slides.Export.PdfOptions();
opts.JpegQuality = 90;
opts.SaveMetafilesAsPng = true;
opts.TextCompression = Aspose.Slides.Export.PdfTextCompression.Flate;
opts.Compliance = Aspose.Slides.Export.PdfCompliance.Pdf15;
pres.Save(FilePath + "\\" + Path.GetFileNameWithoutExtension(InputFileName) + ".pdf", Aspose.Slides.Export.SaveFormat.Pdf, opts);


Exception:

Hi Adnan,

Please let me know if you have any updates. We are receiving huge amount of support tickets from our customers and we fear we might lose lot of customers because of this issue. We have been Aspose customer for a long time and we feel we are let down by Aspose. Document to PDF conversion is the heart of our application and without the conversion our application (which is used by lot of enterprise customer) will not work at all. Please let me know how we can escalate this issue to a higher level in Aspose. I request your team to provide a quick fix till this issue is resolved.

Looking forward to response.

Thanks
Anbu
