說明 |
差不多所有數碼相機都會有把圖像保存為JPEG的選項。JPEG格式支持每色8位(紅,綠,藍),文件大小也比較小。只要不使用重度壓縮,圖像質量不會受太大的影響。不過JPEG文件如果不斷被修改,保存的話,很有可能會退化。若您計劃以後修改照片圖像,或不能接受圖像失真,把它們保存為非JPEG的無損圖像格式的話會比較好。話雖如此,JPEG大致上是最適合網絡發佈的格式。 |
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. |
