说明 |
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。 |
TARGA File Format, is a raster graphics file format. It was the native format of Truevision Inc.'s TARGA and VISTA boards, which were the first graphic cards for IBM-compatible PCs to support Highcolor/truecolor display. |
