The most succinct format is 0x hex representation as mentioned in the docs.

But I use a more obvious and "readable" binary specification, as follows:

-- binary string to number
local function b(e)
    return tonumber(e, 2)
end

pattern = {	--  diagonal lines
    b('11110000'),
    b('11100001'),
    b('11000011'),
    b('10000111'),
    b('00001111'),
    b('00011110'),
    b('00111100'),
    b('01111000'),
}

Other versions of FreeHand might have different patterns.

There may be more but I've not been able to find a download of version 1.7.x which added patterns.

There might be nothing new in a lot of these Apple apps.

original patterns are stored as a PAT# rsrc in the resource fork of MacPaint

I'm happy to submit my pattern collection.

• Will have to dig for old screens, because they have been decomposed into just the 8x8 patterns, with no references as to where they came from.
  I decided to capture most of them again as I had kept all the apps installed.

• I have a script that sorts them by brightness, and I keep only those with brightness between 128 and 255, as the lower half of the range can be filled with inverted patterns.

• I store them as pgm text based image format, which makes processing them easier and makes removing duplicates much easier as there is no need to deal with differences in image compression, colour depth, etc.

• I'm still figuring out a way to deal with patterns that are the same but offset. Maybe there's a rule that can be introduced to unify the offset?

• I use Piskel to split an image/screengrab into tiles, at which point it can save them as a handy zip. Let me know if you want more info!
