說明 | MrSID is an acronym that stands for multiresolution seamless image database. It is a file format (filename extension .sid) developed and patented by LizardTech for encoding of georeferenced raster graphics, such as orthophotos. | JPEG 2000是一個基於小波的圖像壓縮標準。JPEG 2000的目的不僅是改善JPEG的壓縮性能,它也增添(或改善)了很多例如可擴展性和可修改性的功能。 |
優點 | Since MrSID files contain multiple scale and quality levels they are claimed to be well suited for streaming over the World Wide Web. Only the requested zoom and area of the image is sent to the browser making the drawing/navigating/viewing performance extremely fast. | 文件大小小很多,質量卻與JPEG不相上下 |
缺點 | not many programs handle it | 沒那麼受歡迎,需要更多電腦資源 |
