Interface ImgMeta

All Known Implementing Classes:

JpegMeta

public interface ImgMeta

Instances of ImgMeta classes must handle reading and writing text comments. (The idea is to do this to images.) A read or write is complete i.e. you write the entire comment at once, as opposed to doing so in increments as with A Writer/Reader. This makes a crash while writing much less likely so that data corruption isn't such a danger.
