Examples
هذا المثال يظهر كيفية إنشاء صورة WebP من صورة أخرى مع نوعية ضغط مختلفة.
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(

image.Save(

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(

image.Save(

image.Save(

}يظهر المثال التالي كيفية تحويل صورة متعددة الصفحات إلى تنسيق WEBP بشكل عام دون الإشارة إلى نوع صورة معين.

string inputFilePath = System.IO.Path.Combine(dir, "Multipage.cdr");
string outputFilePath = System.IO.Path.Combine(dir, "Multipage.cdr.webp");

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));
}
