Examples
Detta exempel visar hur man skapar en multi-frams animerad WebP-bild med de angivna alternativen.
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();
// The default frame plus 36 + 36 additional frames.
createOptions.AnimLoopCount = 36 + 36 + 1;
// Create a WebP image of 100x100 px.
using (Aspose.Imaging.FileFormats.Webp.WebPImage webPImage = new Aspose.Imaging.FileFormats.Webp.WebPImage(100, 100, createOptions))
{
// The first circle is red
Aspose.Imaging.Brushes.SolidBrush brush1 = new Aspose.Imaging.Brushes.SolidBrush(Aspose.Imaging.Color.Red);
// The second circle is black
Aspose.Imaging.Brushes.SolidBrush brush2 = new Aspose.Imaging.Brushes.SolidBrush(Aspose.Imaging.Color.Black);
// Gradually inscrease the angle of the red arc shape.
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);
}
// Gradually inscrease the angle of the black arc and wipe out the red arc.
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);
}
// Save to a WebP file
webPImage.Save(dir + "output.webp");

Examples
Följande exempel laddar upp en WEBP-bild och skriver ut information om rådataformat och alfa-kanal.
string dir = "c:\\temp\\";
string fileName = dir + "sample.webp";
using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(fileName))
{
Aspose.Imaging.FileFormats.Webp.WebPImage webpImage = (Aspose.Imaging.FileFormats.Webp.WebPImage)image;
// If the active TIFF frame has alpha channel, then the entire TIFF image is considered to have alpha channel.
System.Console.WriteLine("ImageFile={0}, FileFormat={1}, HasAlpha={2}", fileName, webpImage.RawDataFormat, webpImage.HasAlpha);
int i = 0;
foreach (Aspose.Imaging.FileFormats.Webp.IFrame frame in webpImage.Blocks)
{
Aspose.Imaging.FileFormats.Webp.WebPFrameBlock frameBlock = frame as Aspose.Imaging.FileFormats.Webp.WebPFrameBlock;
if (frameBlock != null)
{
System.Console.WriteLine("Frame={0}, FileFormat={1}, HasAlpha={2}", i++, frameBlock.RawDataFormat, frameBlock.HasAlpha);
}
}
}
