Unfortunately, even if I thought about it for days I have no ideas about how to start, can I have any advice?

Try, for every pattern, to generate rows that already match the requirements of the pattern, and then you can assemble these rows into matrices (see the recursion here?)

Probably the best strategy here is to "divide and impera". Create algorithms that work for each property, then put them together. I can't say more than this.

Totally agree, you can't take such a big problem all together. Think how to solve each small step.

You can model the problem as a "Game Tree" where the state (node) is the current matrix/image that gets built and the "move" (edge) is adding something to the image so that you go into another state.

In the end, you should hit a final state in which the image is complete. In the case of a pattern, think well at the "moves" you have to do to keep your solution valid. Hope this helps.
