Subject: Re: Reading Images

Fleck, thanks for this really good answer, but could you tell then what
other data format may I use to avoid such parsings? I don't want to use
anything extra. Dunno about RMagick, but I've seen some rubyrames
example, where it's also done easy, but I wanna make it with ass few
external libs as possible, that's the idea  - I wanna see if ruby "da
solo" is enough to coupe with such problems.
