Jpeg2000Options.Irreversible

Jpeg2000Options.Irreversible property

Gets or sets a value indicating whether use the irreversible DWT 9-7 (true) or use lossless DWT 5-3 compression (default).

public bool Irreversible { get; set; }

Examples

This example shows how to create a PNG image and save it to JPEG2000 with the desired options.

[C#]

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

// Create a PNG image of 100x100 px.
using (Aspose.Imaging.FileFormats.Png.PngImage pngImage = new Aspose.Imaging.FileFormats.Png.PngImage(100, 100))
{
    Aspose.Imaging.Graphics graphics = new Aspose.Imaging.Graphics(pngImage);

    // Fill the entire image in red.
    Aspose.Imaging.Brushes.SolidBrush brush = new Aspose.Imaging.Brushes.SolidBrush(Aspose.Imaging.Color.Red);
    graphics.FillRectangle(brush, pngImage.Bounds);

    Aspose.Imaging.ImageOptions.Jpeg2000Options saveOptions = new Aspose.Imaging.ImageOptions.Jpeg2000Options();

    // Use the irreversible Discrete Wavelet Transform 9-7
    saveOptions.Irreversible = true;

    // JP2 is the "container" format for JPEG 2000 codestreams.
    // J2K is raw compressed data, without a wrapper.
    saveOptions.Codec = Imaging.FileFormats.Jpeg2000.Jpeg2000Codec.J2K;

    // Save to a file
    pngImage.Save(dir + "output.j2k", saveOptions);
