He has also developed a number of other programs, including the Tiny C Compiler.<\/p>\n<p>According to Bellard the main advantages of the new BPG image format are:<\/p>\n<ul>\n<li>High compression ratio. Files are much smaller than JPG for similar quality.<\/li>\n<li>Supported by most Web browsers with a small Javascript decoder (gzipped size: 71 KB).<\/li>\n<li>Based on a subset of the HEVC open video compression standard.<\/li>\n<li>Supports the same chroma formats as JPG (grayscale, YCbCr 4:2:0, 4:2:2, 4:4:4) to reduce the losses during the conversion. An alpha channel is supported. The RGB, YCgCo, and CMYK color spaces are also supported.<\/li>\n<li>Native support of 8 to 14 bits per channel for a higher dynamic range.<\/li>\n<li>Lossless compression is supported.<\/li>\n<li>Various metadata (such as EXIF, ICC profile, XMP) can be included.<\/li>\n<\/ul>\n<p>Bellard said that Mozilla did a study of various lossy compressed image formats, and\u00a0BPG was a clear winner by a wide margin.<\/p>\n<p>\u201cBPG natively supports 8 to 14 bits per channel when most other formats use 8 bits, including most of the JPG implementations and WEBP,\u201d said Bellard.<\/p>\n<p>\u201cIt gives a higher dynamic range (which is important for cameras and new displays) and a slightly better compression ratio (because there are less rounding errors in the decoder).\u201d<\/p>\n<p><em><strong><a title=\"BPG\" href=\"http:\/\/bellard.org\/bpg\/\" target=\"_blank\">More about BPG here<\/a><\/strong><\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Fabrice Bellard has developed a new image format called BPG (Better Portable Graphics), with the aim of replacing JPG<\/p>\n","protected":false},"author":23,"featured_media":93603,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_sma_x_autopost_status":"idle","_sma_x_autopost_error":"","_sma_x_post_id":"","_sma_facebook_post_id":"","_sma_instagram_post_id":"","_sma_threads_post_id":"","_sma_x_attempts":0,"footnotes":""},"categories":[17],"tags":[36,27961,27965,27963],"class_list":["post-115669","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-technology","tag-active","tag-bpg","tag-fabrice-bellard","tag-jpg"],"_links":{"self":[{"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/posts\/115669"}],"collection":[{"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/users\/23"}],"replies":[{"embeddable":true,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/comments?post=115669"}],"version-history":[{"count":1,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/posts\/115669\/revisions"}],"predecessor-version":[{"id":115671,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/posts\/115669\/revisions\/115671"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/media\/93603"}],"wp:attachment":[{"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/media?parent=115669"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/categories?post=115669"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/tags?post=115669"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
