My wife and I are working on a programming project together. I have a |
2 |
number of transparent .gif files that I've converted to BMP with |
3 |
imagemagick's convert command. I'm trying to discover what their |
4 |
background color is so that I can make the backgrounds transparent once |
5 |
again. I've discovered the identify command. Here's one image |

The background of the image looks green to me (0, 255, 0), but identify |
70 |
claims it's white. Is there a way I can know for sure without having to |
71 |
go through all the RGB codes? The convert created BMP's won't open in |
72 |
gimp.... |
