Examples

This example shows how to create a WebP image from another raster image with different compression quality.

[C#]

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

// Load a GIF animation
using (Aspose.Imaging.Image image = new Aspose.Imaging.Image.Load(dir + "test.gif"))
{
    // for lossless compression, increasing the quality setting increases the compression quality and decreases the file size
    image.Save(
        dir + "output_lossless_20.webp",
        new  Aspose.Imaging.ImageOptions.WebPOptions() { Lossless = true, Quality = 20 }); // file size: 42 KB

    image.Save(
        dir + "output_lossless_50.webp",
        new  Aspose.Imaging.ImageOptions.WebPOptions() { Lossless = true, Quality = 50 }); // file size: 41 KB

    image.Save(
        dir + "output_lossless_80.webp",
        new  Aspose.Imaging.ImageOptions.WebPOptions() { Lossless = true, Quality = 80 }); // file size: 40 KB


    // for lossy compression, increasing the Quality value increases the image quality and increases the file size
    image.Save(
        dir + "output_lossy_20.webp",
        new  Aspose.Imaging.ImageOptions.WebPOptions() { Lossless = false, Quality = 20 }); // file size: 24 KB

    image.Save(
        dir + "output_lossy_50.webp",
        new  Aspose.Imaging.ImageOptions.WebPOptions() { Lossless = false, Quality = 50 }); // file size: 36 KB

    image.Save(
        dir + "output_lossy_80.webp",
        new  Aspose.Imaging.ImageOptions.WebPOptions() { Lossless = false, Quality = 80 }); // file size: 51 KB
}
