Nothing to see here….
I’ve hit somewhat of a brick wall. I managed to get some morphological hit&miss code that thinned the images down to 1px wide and it worked fine on the previously posted test. However after that I started getting horrible loops … Continue reading
A sample of a ‘scanned’ puzzle.
So this is a section of a sudoku puzzle as the code sees it: <img src="http://www.thelostsouls.org.uk/wp-content/uploads/2010/06/binarysample.jpg" alt="" title="Binary Sample" width="800" height="399" class="size-full wp-image-65" srcset="https://www.thelostsouls.org.uk/wp-content/uploads/2010/06/binarysample Continued.jpg 800w, https://www.thelostsouls.org.uk/wp-content/uploads/2010/06/binarysample-300×149.jpg 300w” sizes=”(max-width: 800px) 100vw, 800px” /> A small section of a Sudoku converting … Continue reading

An address of a pointer as opposed to a pointer to a pointer?
EDIT@22:14 I take it back. The data was getting borked on exit from the function. Turns out that the code in use had RETURN() as a macro which freed the pointer I was using when I called RETURN(TRUE). Haha…. still … Continue reading

Well that was sodding hard work….
OK so I’ve praised MagicWand now I feel I can curse it. I want a 1bit BMP out of the thing. A bitmap is easy, it’s smart. I write something ending in jpg it writes a jpg, I want a … Continue reading

MagickWand and OCR

A strange bug moving from 64bit to 32bit.
So I installed an SSH client on my iPhone today, TouchTerm (which so far I think is excellent, especially how it handles ctrl keys etc.), and the first thing I do? SSH to my server and compile the previously mentioned … Continue reading
It lives!
Finally. Stripped out loads of code having realised that keeping a list of possible answers to each square is all well and good but the computational time spent maintaining it outweighs the benefits of just err.. well figuring it out … Continue reading
A short note on arrays and ncurses with a bit of a git.
So ncurses operates on a y,x co-ordinate system. All of it’s functions expect y first, for example: getyx(y,x); which gets the location of the cursor putting the values into y and x. This sounds a bit counter intuitive to us, … Continue reading
