Enum `AlphaColorMode`

enum AlphaColorMode

Handling of color channels in transparent images. For Encoder::with_alpha_color_mode

Variants

UnassociatedDirty

Use unassociated alpha channel and leave color channels unchanged, even if there's redundant color data in transparent areas.

UnassociatedClean

Use unassociated alpha channel, but set color channels of transparent areas to a solid color to eliminate invisible data and improve compression.

Premultiplied

Store color channels of transparent images in premultiplied form. This requires support for premultiplied alpha in AVIF decoders.

It may reduce file sizes due to clearing of fully-transparent pixels, but may also increase file sizes due to creation of new edges in the color channels.

Note that this is only internal detail for the AVIF file. It does not change meaning of RGBA in this library — it's always unassociated.
