how to resize an image without loosing its quality in c#.net
?
Stream myBlob;
var encoder = new JpegEncoder();using (var output = new MemoryStream())
using (SixLabors.ImageSharp.Image<Rgba32> image = Image.Load(myBlob))
{ var divisor = image.Width / 100;
var height = Convert.ToInt32(Math.Round((decimal)(image.Height/divisor)));
image.Mutate(x => x.Resize(320, 640));
image.Save(output, encoder);
output.Position = 0;
await blockBlob.UploadFromStreamAsync(output);
}
You can use the overloaded Bitmap constructor to create the new re-sized image, as can be seen bellow:
public static Image Resize(Image image, Size size)
{
return (Image)(new Bitmap(image, size));
}
And you call it using:
var result = Resize(image, new Size(320,640));
