}
Expand description

Different normal forms of buffers.

A normal form is an unaliased buffer with some additional constraints. The ÌmageBuffer uses row major form with packed samples.

Variants§

§

Unaliased

No pixel aliases another.

Unaliased also guarantees that all index calculations in the image bounds using dim_index*dim_stride (such as x*width_stride + y*height_stride) do not overflow.

§

PixelPacked

At least pixels are packed.

Images of these types can wrap [T]-slices into the standard color types. This is a precondition for GenericImage which requires by-reference access to pixels.

§

ImagePacked

All samples are packed.

This is orthogonal to PixelPacked. It requires that there are no holes in the image but it is not necessary that the pixel samples themselves are adjacent. An example of this behaviour is a planar image layout.

§

RowMajorPacked

The samples are in row-major form and all samples are packed.

In addition to PixelPacked and ImagePacked this also asserts that the pixel matrix is in row-major form.

§

ColumnMajorPacked

The samples are in column-major form and all samples are packed.

In addition to PixelPacked and ImagePacked this also asserts that the pixel matrix is in column-major form.
