DicomImageRotate Method (Single, Boolean, Color)
[!:RasterCahcedMultipageImage.Rotate] image around the center.

Namespace: Aspose.Imaging.FileFormats.Dicom
Assembly: Aspose.Imaging (in Aspose.Imaging.dll) Version: 20.06
Syntax
public override void Rotate(
	float angle,
	bool resizeProportionally,
	Color backgroundColor
)

Parameters

angle
Type: SystemSingle
The rotate angle in degrees. Positive values will rotate clockwise.
resizeProportionally
Type: SystemBoolean
if set to true you will have your image size changed according to rotated rectangle (corner points) projections in other case that leaves dimensions untouched and only internal image contents are rotated.
backgroundColor
Type: Aspose.ImagingColor
Color of the background.
Examples
This example shows how to rotate all pages of a DICOM image and save them all to a multi-frame TIFF image.
[C#]

string dir = "c:\\temp\\";

// Load a DICOM image from a file stream.
using (System.IO.Stream stream = System.IO.File.OpenRead(dir + "multiframe.dicom"))
{
    using (Aspose.Imaging.FileFormats.Dicom.DicomImage dicomImage = new Aspose.Imaging.FileFormats.Dicom.DicomImage(stream))
    {
        // Rotate the image around the center by 60 degrees clockwise.
        // Use gray as the background color.
        dicomImage.Rotate(60, true, Aspose.Imaging.Color.Gray);

        Aspose.Imaging.ImageOptions.TiffOptions createOptions = new Aspose.Imaging.ImageOptions.TiffOptions(Imaging.FileFormats.Tiff.Enums.TiffExpectedFormat.Default);
        createOptions.Compression = Aspose.Imaging.FileFormats.Tiff.Enums.TiffCompressions.Deflate;

        // Note that if the image is colorful, it will be automatically converted to the grayscale format according to the options below
        createOptions.Photometric = Aspose.Imaging.FileFormats.Tiff.Enums.TiffPhotometrics.MinIsBlack;
        createOptions.BitsPerSample = new ushort[] { 8 };

        // Create an array of TIFF frames.
        // The number of the frames is equal to the number of the DJVU pages.
        Aspose.Imaging.FileFormats.Tiff.TiffFrame[] tiffFrames = new Aspose.Imaging.FileFormats.Tiff.TiffFrame[dicomImage.DicomPages.Length];

        // Save each page as an individual TIFF frame.
        foreach (Aspose.Imaging.FileFormats.Dicom.DicomPage dicomPage in dicomImage.DicomPages)
        {
            // Create a TIFF frame based on the DICOM page.
            tiffFrames[dicomPage.Index] = new Aspose.Imaging.FileFormats.Tiff.TiffFrame(dicomPage, createOptions);
        }

        // Compose a TIFF image from the frames.
        using (Aspose.Imaging.FileFormats.Tiff.TiffImage tiffImage = new Aspose.Imaging.FileFormats.Tiff.TiffImage(tiffFrames))
        {
            // Save to a file.
            tiffImage.Save(dir + "multiframe.tif");
        }
    }
}
