Wrong document page count

[bstojanovic]

Hi ,
After updating Spire.Pdf to version 9.5.4 and Spire.Doc to version 11.5.6 we notes problem that sometime document after loading from saved blob has page.count 0 and other time same document has page.count in this case 27. All we do is getting data from azure blob to PdfDocument

byte[] fileData data receive by reading from blob
PdfDocument doc = new PdfDocument();
doc.LoadFromBytes(fileData);
doc.Page.Count =>some time 0 sometime 27

Please check more then once we can't conclude anything and we did not change file in any way.
File is more then 3MB so I can't send it trough this form , is there a way to send this file to you?

Regards

I created a smaller sample of a code where you can see this behavior, we load file from disk in to PdfDocument , do some watermarking , and save it to disk . When we load saved version it shows 0 pages instead of 27 as document originally had. This behavior we can't see in all files just some. My file has a little over 3M so I can't upload it is there any other way to send it?
Code :

PdfDocument doc = new PdfDocument();
doc.LoadFromFile(@"someLocation\Fridge Freezer.pdf");

SizeF sizeP = doc.Pages[0].Size;
int fontSize = 0;
string text = "ITS";
foreach (PdfPageBase page in doc.Pages)//page count is 27
{
PdfTilingBrush brush = new PdfTilingBrush(new SizeF(page.Canvas.ClientSize.Width / 2, page.Canvas.ClientSize.Height / 3));
if (page.Canvas.ClientSize.Width > page.Canvas.ClientSize.Height * 1.3)
{
brush = new PdfTilingBrush(new SizeF(page.Canvas.ClientSize.Width / 3, page.Canvas.ClientSize.Height / 2));
}
else if (page.Canvas.ClientSize.Width * 1.3 < page.Canvas.ClientSize.Height)
{

brush = new PdfTilingBrush(new SizeF(page.Canvas.ClientSize.Width / 2, page.Canvas.ClientSize.Height / 3));
}
else
{
brush = new PdfTilingBrush(new SizeF(page.Canvas.ClientSize.Width / 2, page.Canvas.ClientSize.Height / 2));
}
if (fontSize == 0 || sizeP != page.Size)
{
sizeP = page.Size;


int textLength = text.Length;
int margin = 0;
if (textLength > 30) margin = 5;
else if (textLength > 20) margin = 10;
else if (textLength > 10) margin = 20;
else if (textLength > 5) margin = 40;
else margin = 50;
if (brush.Size.Width < brush.Size.Height)
{
fontSize = CalculateFont(brush.Size.Width * 1.14 - brush.Size.Width * margin / 100, text, 20);
}
else
{
fontSize = CalculateFont(brush.Size.Height * 1.14 - brush.Size.Height * margin / 100, text, 20);
}

}
brush.Graphics.SetTransparency(0.3f);
brush.Graphics.Save();
brush.Graphics.TranslateTransform(brush.Size.Width / 2, brush.Size.Height / 2);
brush.Graphics.RotateTransform(-45);
brush.Graphics.DrawString(text, new PdfFont(PdfFontFamily.Helvetica, fontSize), PdfBrushes.Violet, 0, 0, new PdfStringFormat(PdfTextAlignment.Center));
brush.Graphics.Restore();
brush.Graphics.SetTransparency(1);
page.Canvas.DrawRectangle(brush, new RectangleF(new PointF(0, 0), page.Canvas.ClientSize));
}


doc.SaveToFile(@"someLocation\Fridge Freezer_new.pdf");
doc.LoadFromFile(@"someLocation\Fridge Freezer_new.pdf");





int a = doc.Pages.Count; //count is 0

We did not go to new version because we hade open issues , now I can say we found new one. The file with 'odt' extension that we were able to convert to 'pdf' we can't convert with latest version, we are reading data from blob but it is the same if you read from some location.
Code example:
MemoryStream memoryStream = new MemoryStream(fileData)
Document document2 = new Document();
DocFileFormat ff1 = new DocFileFormat();
ff1= DocFileFormat.Odt;
document2 = new Document(memoryStream, ff1);

it breaks on last line. Test with some other documents work, but with document in attachment it breaks with wrong type message. This conversion with older version that we are still on (PDF 9.1.0 version, Doc 11.1.0 version) is working with the same file .
Regards.
