Class Jpeg2000Options

Namespace: Aspose.Imaging.ImageOptions
Assembly: Aspose.Imaging.dll (25.7.0)

Create JPEG2000 (JP2) image files with our API, utilizing advanced wavelet technologyfor coding lossless content. Benefit from support for various codecs, includingirreversible and lossless compression, as well as XMP metadata containers, ensuringversatility and high-quality image creation tailored to your needs.

Examples

The following example shows how to convert a multipage vector image to JPEG 2000 format in general way without referencing to a particular image type.

string dir = "C:\\aspose.imaging\\net\\misc\\ImagingReleaseQATester\\Tests\\testdata\\2548";
   string inputFilePath = System.IO.Path.Combine(dir, "Multipage.cdr");
   string outputFilePath = System.IO.Path.Combine(dir, "Multipage.cdr.j2k");
   Aspose.Imaging.ImageOptionsBase exportOptions = new Aspose.Imaging.ImageOptions.Jpeg2000Options();
   using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(inputFilePath))
   {
       exportOptions.MultiPageOptions = null;
       if (image is Aspose.Imaging.IMultipageImage multipageImage && multipageImage.Pages != null && multipageImage.PageCount > 2)
       {
           exportOptions.MultiPageOptions = new Aspose.Imaging.ImageOptions.MultiPageOptions(new Aspose.Imaging.IntRange(0, 2));
       }
       if (image is Aspose.Imaging.VectorImage)
       {
           exportOptions.VectorRasterizationOptions = (Aspose.Imaging.ImageOptions.VectorRasterizationOptions)image.GetDefaultOptions(new object[] { Aspose.Imaging.Color.White, image.Width, image.Height });
           exportOptions.VectorRasterizationOptions.TextRenderingHint = Aspose.Imaging.TextRenderingHint.SingleBitPerPixel;
           exportOptions.VectorRasterizationOptions.SmoothingMode = Aspose.Imaging.SmoothingMode.None;
       }
       image.Save(outputFilePath, exportOptions);
   }
