entY8 Posted October 4, 2006 Share Posted October 4, 2006 what does "100% quality" actually mean, when you save the picture as jpeg? will every pixel contain exactly the same color value as before? but somehow it doesn't seem to be this way, since when trying it out some colors actually changed :?

l4c_1 Posted October 4, 2006 Share Posted October 4, 2006 my understanding is that reducing the quality (that is, less than 100%) decreases the palette information (colors available to the image), beginning with the least often occuring colors (or colors that don't appear at all). Usually if you save an image as 85+% you should notice very little or no change at all (although you may notice change if you magnify and examine the pixels of the image). hope that helps...if someone else can explain it better, go for it!

entY8 Posted October 4, 2006 Author Share Posted October 4, 2006 Lots of info here:http://en.wikipedia.org/wiki/Jpeg yeah, lots; too many actually :? (since it also differs between the precise jpeg formats)if you oversee the data clearly, could you please tell me what "100%" quality actually means? (i couldn't find it there in five minutes searching) Quote Link to comment Share on other sites More sharing options...
BoltBait Posted October 4, 2006 Share Posted October 4, 2006 Sorry, but the jpeg format implemented in Paint.net is not lossless--even at 100% quality. Quote Download: BoltBait's Plugin Pack | CodeLab | and a Free Computer Dominos Game Link to comment Share on other sites More sharing options...

Picc84 Posted October 5, 2006 Share Posted October 5, 2006 Yes, now.. hears a question, is it worth having it at 100%? because all the pictures i upload to the internet are .jpeg's... should I use 100% when memorie is not an issue? Quote Link to comment Share on other sites More sharing options...
SHMCMINN Posted October 6, 2006 Share Posted October 6, 2006 I reccomend saving in PNG format if you want the best quality, it saves it almost exactly pixel by pixel. Quote Link to comment Share on other sites More sharing options...
Illnab1024 Posted October 6, 2006 Share Posted October 6, 2006 It does save lossless, it just compresses very well... Quote ~~ Link to comment Share on other sites More sharing options...
