Dopo tre anni di sviluppo, \u00e8 stata pubblicata la specifica per il formato delle immagini AVIF 1.2 (AV1 Image Format), che utilizza tecnologie di compressione intra-frame impiegate nel formato di codifica video AV1. Il contenitore per la distribuzione dei dati nel formato AVIF \u00e8 simile a HEIF. Oltre alle immagini in gamma dinamica standard (SDR), AVIF supporta immagini in gamma dinamica elevata (HDR, High Dynamic Range) e in spazio colorimetrico Wide-gamut. <\/p>\n

Nella nuova versione \u00e8 stata standardizzata la supporto del meccanismo \u00abSample Transform\u00bb, che consente di creare un'immagine finale combinando una o pi\u00f9 immagini ausiliarie e costanti, utilizzando trasformazioni matematiche sui pixel, il cui tipo e parametri vengono conservati nell'area dei metadati. Ad esempio, questo meccanismo pu\u00f2 essere utilizzato per generare immagini con una maggiore profondit\u00e0 di colore partendo da immagini a bassa profondit\u00e0 di colore, mantenendo al contempo la retrocompatibilit\u00e0. Nella libreria libavif, che offre un'implementazione di riferimento del formato AVIF, il supporto sperimentale per \u00abSample Transform\u00bb \u00e8 presente da aprile 2024.
