例子

此示例说明如何使用指定选项创建多帧动画 WebP 图像。

[C#]

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

Aspose.Imaging.ImageOptions.WebPOptions createOptions = new Aspose.Imaging.ImageOptions.WebPOptions();
createOptions.Lossless = true;
createOptions.Quality = 100f;
createOptions.AnimBackgroundColor = (uint)Aspose.Imaging.Color.Gray.ToArgb();

// 默认帧加上 36 + 36 个附加帧。
createOptions.AnimLoopCount = 36 + 36 + 1;

// 创建一个 100x100 像素的 WebP 图像。
using (Aspose.Imaging.FileFormats.Webp.WebPImage webPImage = new Aspose.Imaging.FileFormats.Webp.WebPImage(100, 100, createOptions))
{
    // 第一个圆圈是红色的
    Aspose.Imaging.Brushes.SolidBrush brush1 = new Aspose.Imaging.Brushes.SolidBrush(Aspose.Imaging.Color.Red);

    //第二个圆圈是黑色的
    Aspose.Imaging.Brushes.SolidBrush brush2 = new Aspose.Imaging.Brushes.SolidBrush(Aspose.Imaging.Color.Black);

    // 逐渐增加红色弧形的角度。
    for (int angle = 10; angle <= 360; angle += 10)
    {
        Aspose.Imaging.FileFormats.Webp.WebPFrameBlock block = new Aspose.Imaging.FileFormats.Webp.WebPFrameBlock(100, 100);
        Aspose.Imaging.Graphics graphics = new Aspose.Imaging.Graphics(block);
        graphics.FillPie(brush1, block.Bounds, 0, angle);

        webPImage.AddBlock(block);
    }

    // 逐渐增加黑色弧线的角度，将红色弧线抹去。
    for (int angle = 10; angle <= 360; angle += 10)
    {
        Aspose.Imaging.FileFormats.Webp.WebPFrameBlock block = new Aspose.Imaging.FileFormats.Webp.WebPFrameBlock(100, 100);

        Aspose.Imaging.Graphics graphics = new Aspose.Imaging.Graphics(block);
        graphics.FillPie(brush2, block.Bounds, 0, angle);
        graphics.FillPie(brush1, block.Bounds, angle, 360 - angle);

        webPImage.AddBlock(block);
    }

    // 保存到 WebP 文件
    webPImage.Save(dir + "output.webp");
}
