Computer program to convert picture to calc grayscale?

[nxtboy III]

Yeahh....
BTW, is this the best grayscale routine or is the one used for rigview better?

Could you help me with my game: http://www.omnimaga.org/index.php?topic=12639

there is a fairly simple way to do what you want using the GIMP. you want to fill in areas that are all one colour with a specific patter, yes?
what you'd need to do is make images with small sections of the patterns you want to use so that, if it were tiled repeatedly, all the lines would match up at the tiles' edges, and then save it as a GIMP pattern (*.pat) file and copy it into the pattern folder wherever you have GIMP installed. from then on, it will appear in your list of patterns. then use the select by colour tool to limit your selection to only the colour you want to replace with the pattern, choose the bucket fill tool, set it to "fill whole selection" and "pattern fill" and you can fill the entire area with that pattern.

Actually, that is what I am doing right now.
But I wanted a very fast way of doing it so I do not have to do it myself.

that seems pretty fast to me, unless you have thousands of images. you're doing this, right?

[nxtboy III]

Yes, I am doing that, but I have to do that 3 times for each image, then save it and everything else. All together that takes a while. That's why I need a program so I can convert tons and tons of files very quickly.

I know that Irfanview has an option to change the color depth to 2 colors (1 bpp) & that you can apply the changes to multiple images. Though I'm not sure if is what you're looking for...

Here's a page I found that mentions more or less how to do it:

umm....
I don't think I can do exactly what I need to on IrfanView...
But thanks anyways.

BlakPilar-
Did you ever happen to make that program?

If there was a program like this that did this nicely that would help greatly.
TokenIDE goes as far as to convert an image to black and white, but not greyscale unfortunately

[nxtboy III]

So there is no program to do this automatically? Could it be easily made?

[Jonius7]

OMG, sorry I didn't realised I'd posted the same post twice
It might be capably possibly to make, however I wouldn't have much of an idea myself though.
