说明 | 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. | 差不多所有数码相机都会有把图像保存为JPEG的选项。JPEG格式支持每色8位(红,绿,蓝),文件大小也比较小。只要不使用重度压缩,图像质量不会受太大的影响。不过JPEG文件如果不断被修改,保存的话,很有可能会退化。若您计划以后修改照片图像,或不能接受图像失真,把它们保存为非JPEG的无损图像格式的话会比较好。话虽如此,JPEG大致上是最适合网络发布的格式。 |
优点 | 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. | 小的文件大小,非常受欢迎 |
缺点 | not many programs handle it | 质量损失 |
