Class ApngOptions
Navne til: Aspose.Imaging.ImageOptions Sammensætning: Aspose.Imaging.dll (25.4.0)
API for animeret PNG (Animated Portable Network Graphics) billedfilformatCreation er et dynamisk værktøj for udviklere, der søger at generere captivatinganimerede billeder. med tilpasningsmuligheder som rammevarighed ogantallet af gange at loop, denne API giver mulighed for fin-tuning animeret indholdefter specifikke behov. uanset om du opretter engagerende webgrafik ellerinteraktive visualer, kan du bruge denne API til at integrereAPNG-billeder med præcis kontrol over animationsparametre.

Examples
Følgende eksempel viser, hvordan man eksporterer apng APNG-filformatet fra andre ikke-animerede multi-page-formater.
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
}Følgende eksempel viser, hvordan man eksporterer til 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
}Følgende eksempel viser, hvordan man opretter APNG-billede fra en anden raster-en-side-bilde.
using Aspose.Imaging;
using Aspose.Imaging.ImageOptions;
using Aspose.Imaging.FileFormats.Apng;
const int AnimationDuration = 1000; // 1 s
const int FrameDuration = 70; // 70 ms
using (RasterImage sourceImage = (RasterImage)Image.Load("not_animated.png"))
{
ApngOptions createOptions = new ApngOptions
{
Source = new FileCreateSource("raster_animation.png", false),
DefaultFrameTime = (uint)FrameDuration,
ColorType = PngColorType.TruecolorWithAlpha,
};
using (ApngImage apngImage = (ApngImage)Image.Create(
createOptions,
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];
float gamma = frameIndex >= numOfFrames2 ? numOfFrames - frameIndex - 1 : frameIndex;
lastFrame.AdjustGamma(gamma);
}
// add last frame
apngImage.AddFrame(sourceImage);
apngImage.Save();
}
