Could you add support for JPEG? For this game I'm helping with has a title screen that in JPEG format is around 40bytes, and in PNG, and TIF is around 500bytes.
Forty bytes? I think you probably mean kilobytes. I've never seen a 40 byte JPEG, and I imagine it would be rather small. =)
JPEG support would be nice, I guess, for those rare cases when you could use it.
You wouldn't be able to get transparency with it (you can't even define a colour as transparent, because solid blocks of colour are not "solid" in JPEG format - they're artifacted)... but if it's a case where you need a JPEG (like a title screen), you probably don't want transparency anyway. =)
I would like to bring this back up as I would like it. I have a lot of image files that are a core component to the game and if they are not in JPEG format they have a 1000% increase in size on average.
JPEG is supported in BYOND 4.0, although frankly I have difficulty believing a properly compressed PNG would be 11× as bulky. If your PNG files aren't compressing down enough, try using advpng which may spare you some space. I recommend it for all PNG files. In fact, if it preserves comments (and I think it does), you can even use it on .dmi files in BYOND 4.0.
hmm, so dmi files are simply png files with comments storing state information and whatnot. Good to know how they technically work, there might be some room to use some imaging effects on an entire icon file now..
