magnum.trade.ImageData2D class

Memory ownership and reference counting

The class can be both owning an non-owning depending on the value of data_flags. If they contain neither DataFlags.OWNED nor DataFlags.GLOBAL, the owner property references the object actually owning the pixel data the image points to. This ensures calling del on the original object will not invalidate the data.

Pixel data access

The class makes use of Python’s dynamic nature and provides direct access to pixel data in their concrete types via pixels. See ImageView2D documentation for more information and usage example.

Compared to Image2D and ImageView2D / MutableImageView2D, the data and pixels views are immutable and mutable access is provided depending on the value of data_flags via mutable_data and mutable_pixels.
