免费在线 SFW 转 RGBA 转换器

Format for bitmap images that were created in the Seattle FilmWorks video editor, which is no longer being actively developed. It was also used to create slideshows. The format has a MGI PhotoSuite file structure that supports bitmap images. SFW files can be converted into JPG images.

This format has the same color structure as RGB, but it includes an alpha channel that is used to display various levels of transparency. The transparency value is set from 0 to 1, where 1 corresponds to opacity. It is described using the CSS3 programming language.
