I am preparing a Powerpoint presentation in which I will be showing a full musical score (lots of horizontal lines). The original scores are being scanned in and sent to me in GIF. The GIFs look fine when they get to me...but when I insert the GIF pic into the Powerpoint slide, it is really missing quite a few of the lines in the score. I was thinking that it might help if I adjusted the Brightness/contrast through Paint.NET. This doesn't really have much effect on it. Any suggestions?
Thanks!
