How to Convert GIFF Image Frame to WebP Image inside .NET Applications
This technical tip explains how .NET developers can Convert GIFF Image Frame to WebP Image inside their .NET applications. Aspose.Imaging enables you to extract a frame or frames from any existing GIFF image and convert it to WebP format. This article shows how you can extract a particular frame from a GIFF image and convert it to a WebP image. Here are some important steps for the conversion, Load an existing GIFF image into an instance of Image using the factory method Load, Create and initialize an instance of GifImage class, Create and initialize an instance of WebPImage class, Access the GIFF image Frame with GifImage.Blocks property, Create and initialize an instance of WebPFrameBlock class, Add WebP frame to WebP image block list, Set WebP image options and Save WebP image.
//your code here...// Converting GIFF Image Frame to WebP Image
//[C# Code Sample]
// Load GIFF image into the instance of image class.
using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(@"D:\animation.gif"))
{
// Create an instance of GIFF image class.
Aspose.Imaging.FileFormats.Gif.GifImage gif = image as Aspose.Imaging.FileFormats.Gif.GifImage;
if (gif == null) return;
// Load an existing WebP image into the instance of WebPImage class.
using (Aspose.Imaging.FileFormats.Webp.WebPImage webp = new Aspose.Imaging.FileFormats.Webp.WebPImage(image.Width, image.Height, null))
{
// Loop through the GIFF frames
for (int i = 0; i < gif.Blocks.Length; i++)
{
// Convert GIFF block to GIFF Frame
Aspose.Imaging.FileFormats.Gif.Blocks.GifFrameBlock gifBlock = gif.Blocks[i] as Aspose.Imaging.FileFormats.Gif.Blocks.GifFrameBlock;
if (gifBlock == null)
{
continue;
}
// Create an instance of WebP Frame instance by passing GIFF frame to class constructor.
Aspose.Imaging.FileFormats.Webp.WebPFrameBlock block = new Aspose.Imaging.FileFormats.Webp.WebPFrameBlock(gifBlock)
{
Top = (short)gifBlock.Top,
Left = (short)gifBlock.Left,
Duration = (short)gifBlock.ControlBlock.DelayTime
};
// Add WebP frame to WebP image block list
webp.AddBlock(block);
}
// Set Properties of WebP image.
webp.Options.AnimBackgroundColor = 0xff; //black
webp.Options.AnimLoopCount = 0; //infinity
webp.Options.Quality = 50;
webp.Options.Lossless = false;
// Save WebP image.
webp.Save(@"D:\saveAnimation.webp");
}
}
