Fixed

• Ensure images are disposed early throughout the codebase (#114).

• Methods which modify the image, such as setting or removing metadata requires an MutableImage (see image.Mutate).

1.2.4

Changed

• Update methods/enums for libvips 8.10.

1.2.3

Added

• Add support for a single shared libvips binary on Linux and macOS (#83).

1.2.1

Fixed

1.2.0

Added

• Add support for true streaming (#33).
  • See the blogpost and the tutorial for more information.
• A new NetVips.Extensions package containing useful helpers (#41).

• Add VipsProgress struct to the public API.
• Add image.WriteToMemory(out ulong) to write the image to an unformatted C-style array.
  • This is a low-level operation, make sure you free the returned memory with NetVips.Free.

Changed

• The image.SetType() function has been renamed to image.Set().
• The Image.Sum() function uses the params keyword.
