Examples
This example shows how to load a JPEG2000 image from a file and save it to PNG.
[C#]
string dir = "c:\\temp\\";
// Load a JPEG2000 image.
using (Aspose.Imaging.FileFormats.Jpeg2000.Jpeg2000Image jpeg2000Image = new Aspose.Imaging.FileFormats.Jpeg2000.Jpeg2000Image(dir + "sample.jp2"))
{
// Save to PNG
jpeg2000Image.Save(dir + "sample.output.png", new Aspose.Imaging.ImageOptions.PngOptions());
