Rotate tiff with Aspose.Pdf

Aspose.Total Product Family

Hi,

I believe this is a sales query, sales believe differently…

I am currently using Aspose.Pdf and cannot find a way to rotate documents.

I have many tiffs that need to be merged into many pdfs; we can pick up tif files and insert them into pdf documents as it, but some tifs have orientations set (for when they were scanned upside down) which doesn’t get picked up during conversion to pdf.

Do I need to purchase Aspose.Imaging in order to check rotation and rotate images where necessary or is this functionality in Aspose.Pdf somewhere?

Thank you.

Please use following code snippet in order to meet your requirements:

// Getting the skew angle from scanned text document
using (RasterImage image = (RasterImage)Image.Load("Sample_01_Upright.tif"))
{
    float skewAngle = image.GetSkewAngle();
    // ...
}

// Get rid of the skewed scan with default parameters
using (RasterImage image = (RasterImage)Image.Load("Sample_01_Upright.tif"))
{
    image.NormalizeAngle();
    image.Save("result.tif");
}

// Get rid of the skewed scan with custom parameters
using (RasterImage image = (RasterImage)Image.Load("skewed.png"))
{
    image.NormalizeAngle(false /*do not resize*/, Color.LightGray /*background color*/);
    image.Save("normalized.png");
}

In case you need further assistance, please feel free to let us know.
