Hi
I just was going to suggest a similar macro. BTW, I noticed, if a macro
takes very long to process or runs totally berserk, how to abort it?
I see there is a built in function to do it, is there a way to access this
from the main window?

Here is a macro that does this:
requires("1.35g");
f = File.open(""); // prompt for file name
for (y=0; y<getHeight; y++) {
showProgress(y, getHeight);
for (x=0; x<getWidth; x++) {
print(f, x+"\t"+y+"\t"+getPixel(x,y));
}
}
