Class ApngOptions
Namn på plats: Aspose.Imaging.ImageOptions Församling: Aspose.Imaging.dll (25.5.0)
API för animerad PNG (Animated Portable Network Graphics) bildfilformatskapande är ett dynamiskt verktyg för utvecklare som vill generera lockandeanimerade bilder. med anpassningsbara alternativ som ramtid ochantal gånger att löpa, detta API tillåter fin-tuning animerad innehållefter specifika behov. oavsett om du skapar engagerande webgrafik ellerinteraktiva visualer, kan du använda denna API för att integreraAPNG-bilder med exakt kontroll över animationsparametrar.

Examples
Följande exempel visar hur man exporterar apng APNG-filformat från andra icke-animerade multi-sidorformat.
using Aspose.Imaging;
using Aspose.Imaging.ImageOptions;
using (Image image = Image.Load("img4.tif")) {
// Setting up the default frame duration
image.Save("img4.tif.500ms.png", new ApngOptions() { DefaultFrameTime = 500 }); // 500 ms
image.Save("img4.tif.250ms.png", new ApngOptions() { DefaultFrameTime = 250 }); // 250 ms
}Följande exempel visar hur man exporterar till APNG-filformat.
using Aspose.Imaging;
using Aspose.Imaging.ImageOptions;
using (Image image = Image.Load("Animation1.webp")) {
// Export to APNG animation with unlimited animation cycles as default
image.Save("Animation1.webp.png", new ApngOptions());
// Setting up animation cycles
image.Save("Animation2.webp.png", new ApngOptions() { NumPlays = 5 }); // 5 cycles
}Följande exempel visar hur man skapar APNG-bild från en annan raster ensidig bild.

using Aspose.Imaging.ImageOptions;
using Aspose.Imaging.FileFormats.Apng;
const int AnimationDuration = 1000; // 1 s
const int FrameDuration = 70; // 70 ms

ColorType = PngColorType.TruecolorWithAlpha,

sourceImage.Width,
sourceImage.Height))
{
// It is possible to set image default frame time there: apngImage.DefaultFrameTime = (uint)FrameDuration;
int numOfFrames = AnimationDuration / FrameDuration;
int numOfFrames2 = numOfFrames / 2;
// Cleaning because the image contains one frame by default
apngImage.RemoveAllFrames();
// add first frame
apngImage.AddFrame(sourceImage);
// add intermediate frames
for (int frameIndex = 1; frameIndex < numOfFrames - 1; ++frameIndex)
{
apngImage.AddFrame(sourceImage);
ApngFrame lastFrame = (ApngFrame)apngImage.Pages[apngImage.PageCount - 1];

lastFrame.AdjustGamma(gamma);
}
// add last frame
apngImage.AddFrame(sourceImage);
apngImage.Save();
}
