Re: Separating, then conversion to matrix

Thanks, there was some extra confusion, because I didn't realise that the image was 'small' [256x 256], so now I can read the first column as x,y [? I hope!] coordinates and the rest as 'colour'.

My ugly way of doing this is currently:
#!/usr/bin/perl -w

Separating, then conversion to matrix

Hi folks

I want to make a matrix of ones and zeros out of some red bits of an image, so:

convert 5446.png -separate -channel Red out.txt

Which give me a file containing lines like this:
146,255: (152,152,152) #989898 rgb(152,152,152)
147,255: (210,210,210) #D2D2D2 rgb(210,210,210)
148,255 ...
