Examples
Contoh ini menunjukkan cara membuat gambar WebP dari gambar raster lain dengan kualitas kompresi yang berbeda.
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
}Contoh berikut menunjukkan bagaimana untuk menukar gambar vektor multipage ke format WEBP secara umum tanpa merujuk pada jenis gambar tertentu.
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.webp");
Aspose.Imaging.ImageOptionsBase exportOptions = new Aspose.Imaging.ImageOptions.WebPOptions();
using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(inputFilePath))
{
exportOptions.MultiPageOptions = null;
// Export only first two pages. These pages will be presented as animated frames in the output WEBP.
Aspose.Imaging.IMultipageImage multipageImage = image as Aspose.Imaging.IMultipageImage;
if (multipageImage != null && (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);
