ImageSharp image -> ImageData ? #119

Closed NnWinter closed 2 years ago

NnWinter commented 2 years ago

An ImageSharp image as var img = new Image(size.Width, size.Height); file.Video.AddFrame() need ImageData

How does it convert?

As I don't know how you load image and which pixel format it has, but here is example for Rgba32:

using var image = Image.Load<Rgba32>(@"/path/to/image.jpg");

// Copy to bytes
byte[] pixelBytes = new byte[image.Width * image.Height * Unsafe.SizeOf<Rgba32>()];
image.CopyPixelDataTo(pixelBytes);

var imageData = ImageData.FromArray(pixelBytes, ImagePixelFormat.Rgba32, image.Width, image.Height);

// Do something with ImageData

Replace Rgba32 with Rgb32 or another px format.
