Examples
L’exemple següent mostra com crear una imatge APNG d’una altra imatge de raster de pàgina única.
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();
}
