Error message

must be a 2d image

What it means

TextureReinterpretationError::WrongDimension: reinterpreting as a 2D (or layered 2D) layout requires a purely 2D image, but the image is 3D — a sentinel guard rejecting the conversion.

Solutions

1. Only reinterpret images whose dimension is TextureDimension::D2
2. Use a different conversion path for 3D textures
3. Check image.texture_dimension() first
