Page orientation.

[vishy]

Hi Team,

Hope you guys are doing great.

Currently we are using Spire.PDF Pro Edition and would like to know following.

Can we progrmatically find the orientration of text/image in page which have gone wrong , so that we can auto rotate pages (90/180/270 degrees) which are disoriented.

Business case -> we have many pdf files which manually has to be rotated because their orientation is wrong.

Thanks,

Hi,

Thanks for your inquiry.
Sorry we can not fulfil your requirement now for we can not get original orientation of image/text in PDF page. But, if your PDF page and its image/text keep the same orientation, you could directly rotate pages by using the following code. If there is any question, welcome to write back and share us a sample PDF file.

Code: Select all

PdfDocument doc = new PdfDocument();
doc.LoadFromFile("Sample1.pdf");
foreach (PdfPageBase page in doc.Pages)
{
    int rotation = (int)page.Rotation;
    if (page.Rotation == PdfPageRotateAngle.RotateAngle90)
    {
        rotation += (int)PdfPageRotateAngle.RotateAngle270;
        page.Rotation = (PdfPageRotateAngle)rotation;
    }
    if (page.Rotation == PdfPageRotateAngle.RotateAngle180)
    {
        rotation += (int)PdfPageRotateAngle.RotateAngle180;
        page.Rotation = (PdfPageRotateAngle)rotation;
    }
    if (page.Rotation == PdfPageRotateAngle.RotateAngle270)
    {
        rotation += (int)PdfPageRotateAngle.RotateAngle90;
        page.Rotation = (PdfPageRotateAngle)rotation;
    }
}
doc.SaveToFile("result.pdf", FileFormat.PDF);
