Dans Chrome sont incluses.<\/a><\/noindex> une nouvelle mise en \u0153uvre de l'interface du visualiseur de documents PDF int\u00e9gr\u00e9. L'interface se distingue par le regroupement dans la barre sup\u00e9rieure de tous les param\u00e8tres. Auparavant, la barre sup\u00e9rieure affichait uniquement le nom du fichier, des informations sur les pages, ainsi que les boutons de rotation, d'impression et de sauvegarde, mais elle int\u00e8gre d\u00e9sormais \u00e9galement le contenu du panneau lat\u00e9ral, qui comprenait les \u00e9l\u00e9ments de contr\u00f4le de zoom et d'ajustement du document \u00e0 la taille de la page. Ajout\u00e9<\/a><\/noindex> la possibilit\u00e9 de sauvegarder des formulaires PDF modifi\u00e9s, ainsi que mode<\/a><\/noindex> la vue en double page.<\/p>\n

Pour activer les nouvelles fonctionnalit\u00e9s, les drapeaux \u00ab chrome:\/\/flags#pdf-viewer-update \u00bb, \u00ab chrome:\/\/flags\/#pdf-form-save \u00bb et \u00ab chrome:\/\/flags\/#pdf-two-up-view \u00bb sont propos\u00e9s.<\/p>\n

\"Un<\/a><\/noindex><\/center><\/p>\n

\"Un<\/a><\/noindex><\/center><\/p>\n

Parmi les changements notables dans Chrome, on peut aussi mentionner l'inclusion<\/a><\/noindex> la prise en charge par d\u00e9faut du format d'images AVIF<\/a><\/noindex> (AV1 Image Format), qui utilise des technologies de compression intra-image du codec vid\u00e9o AV1. Le conteneur pour la distribution de donn\u00e9es compress\u00e9es en AVIF est enti\u00e8rement analogue \u00e0 HEIF. AVIF prend en charge tant les images HDR (High Dynamic Range) et l'espace colorim\u00e9trique Wide-gamut que celles en plage dynamique standard (SDR). Dans Firefox, le support exp\u00e9rimental d'AVIF a \u00e9t\u00e9 ajout\u00e9 dans la version Firefox 77 (activ\u00e9 via image.avif.enabled dans about:config).<\/p>\n

Auparavant, Chrome mettait en avant le format d'images WebP<\/a><\/noindex>, qui permettait \u00e0 Google de r\u00e9duire la taille des fichiers images de 25% \u00e0 34% tout en maintenant la qualit\u00e9 au niveau du format JPEG. Des tests alternatifs les tests<\/a><\/noindex> , montrent que WebP n'est pas aussi efficace que souhait\u00e9 \u2014 si on ne le compare pas \u00e0 l'encodeur de r\u00e9f\u00e9rence cjpeg du JPEG Group, mais en utilisant un encodeur plus efficace, montrent<\/a><\/noindex>, ce qui signifie que WebP n'est pas aussi efficace que souhait\u00e9 \u2014 si l'on le compare non pas \u00e0 l'encodeur de r\u00e9f\u00e9rence cjpeg du JPEG Group, mais en utilisant un encodeur plus efficace. , le gain de WebP n'est perceptible que pour des r\u00e9solutions faibles (500px), les plus couramment utilis\u00e9es sur le Web. \u00c0 une r\u00e9solution de 1000px, le r\u00e9sultat est presque identique, et \u00e0 1500px, WebP est m\u00eame moins performant que MozJPEG. AVIF surpasse consid\u00e9rablement MozJPEG, cjpeg et WebP dans les m\u00eames tests, et est donc consid\u00e9r\u00e9 par les fabricants de navigateurs comme un format plus prometteur.<\/a><\/noindex>Une nouvelle impl\u00e9mentation de l'interface du visualiseur de documents PDF int\u00e9gr\u00e9 a \u00e9t\u00e9 incluse dans Chrome.<\/p>\n
