QUESTION

How can I display a sudoku solution as an image using C

Asked 2021-May-27 at 18:15

I made a backtracking code which solves a sudoku and I want to display it on the screen using C libraries. I know that I can use GTK, but I think it is too complicated for my level.

How can I create an image with the solution displayed on a sudoku grid. It doesn't need to create the grid too, it is ok if I use an image with a grid as an input. So basically, I have a matrix (the sudoku solution) and I want to display it as an image.

I mention that I use VSC on a Virtual Machine with Mint.

ANSWER

Answered 2021-May-27 at 18:15

From my top comments ...

I assume you already have a 2D matrix that represents your board position.

You might consider using SDL2 instead of GTK as it's much simpler and can display directly to a window.

Or, you can create an image file and then use system to invoke a display program (e.g. ImageMagick's display command). It's pretty easy to output a .bmp file. Or, you could create a .ppm format file--that's even simpler.

You could even output text graphics as a sudoku representation isn't too complex.

ImageMagick's convert can convert a format to any other format.

Thank you for your help! I still have a question. @CraigEstey, How do I convert my 2D matrix who looks like a sudoku into a matrix that can be displayed as a ppm or bmp. I assume that I need to have a matrix of pixels for that. – Ionut Becheru

Yes, you'll need a pixel matrix.

But, if you just create that yourself, you'll have to create a bunch of drawing primitives for drawing rectangles, drawing text fonts, adding colors, etc. In particular, drawing text into an image is complicated (we need a font definition).

So, once again, I suggest using a graphics package that does all that for you. And, again, I suggest SDL2.

In addition to the development package for SDL2, [on fedora, at least], you'll need to install the development package for SDL2_ttf. And, you'll need the font packages.

So, you'll need:

Sudoku algorithm generates duplicate values

ANSWER

Answered 2021-May-21 at 20:09

The main issue is that you are only looking at the original grid to restrict values, whereas really you need to know about the trial values that you have put in your solution grid of Cells. So adjust your gen_possible_for to look at the Cells, not the original puzzle grid.

You also need to make sure that you clear Cell values as you backtrack past them, in that case, and have a way of backtracking past prefilled cells. And you need to hold the list of possible values for each cell (until you backtrack past it); if you .pop() values from this list then you don't also need to keep track of visit numbers.

So you want to find the (index-of) the minimum element according to some metric – in your case number of Nothing elements, but clearly this is a special case of a more general concept: you have some function a -> Int to be used on the elements of an [a] list. In other words, you need a helper with a signature like either

Understanding what you have so far would be easier with a bit more of your code and data structures. Commonly (but definitely not always), a sudoku board is set up as list of rows, each of which is a list of numbers, zeroes representing blanks:
