I need to redraw a map using a palette of certain colors. There cannot be any other colors in the map but those which are included in the palette. However, as I am drawing a new map upon an old one, there are colors from the old map. Maybe I should have started drawing on two layers or something (too late, I have made it a bmp already), I am not sure, because I am novice at photoshop, however, I have some ideas, how can I solve this problem. First of all, could you tell me, is there a way to make the pencil ignore certain colors (not color over them) but color over all the other colors? For example, I have a green patch which I do not want to color, but I want to color everything (each pixel) around it. The background consists of different colors. Another thing - maybe I can "filter" the unnecesery color out? Like telling the image that - all the colors which are not in this palette should be erased. Any ideas?
PS
The image is 10400x10400 bmp. It is being made for a program which will generate a computer game map file from it, that is why no pixel can be of other color than that which is included in the palette. And I am using PS CS2!
Thanks. |
