Basically whats going on here is were create an image using the land map generation library which I have wrapped in a service called CreateMapService. This on its own, because we are creating an image, takes a smidge.
But on to the real meat.
The rest of this walks over 350 pixels (349 because of imagecolorat) then I check if the x, y are the waterRgb.
If so, I then attempt to create (as long as it doesn't exist, see why below) a port. To do this, if we are on water, we check in all 8 directions around that pixel to se if there is land, if there is we do a random check to see if we should create a port or not. If so we create the location with is_port set to true.
This is why, as above, I stated we check if the location exists, so we don't re-create it.
The issue is that this seed takes more then 10 minutes to create. I expect with the image generation for it to take at least a few minutes, it has to create the image.
I also expect a few minutes for the looping and the checking, but I feel it shouldn't take up to and including 30+ minutes.
So my question for you is how do I make this code cleaner, more robust and faster (if possible) (not counting the image generation part)

Basically whats going on here is were create an image using the land map generation library which I have wrapped in a service called CreateMapService. This on its own, because we are creating an image, takes a smidge.
But on to the real meat.
The rest of this walks over 350 pixels (349 because of imagecolorat) then I check if the x, y are the waterRgb.
If so, I then attempt to create (as long as it doesn't exist, see why below) a port. To do this, if we are on water, we check in all 8 directions around that pixel to se if there is land, if there is we do a random check to see if we should create a port or not. If so we create the location with is_port set to true.
This is why, as above, I stated we check if the location exists, so we don't re-create it.
The issue is that this seed takes more then 10 minutes to create. I expect with the image generation for it to take at least a few minutes, it has to create the image.
I also expect a few minutes for the looping and the checking, but I feel it shouldn't take up to and including 30+ minutes.
So my question for you is how do I make this code cleaner, more robust and faster (if possible) (not counting the image generation part)

I don't proclaim to be the best developer, but I am always looking for new ways to learn how to improve my code. I have never posted on this stack section before so please be gentle.
consider the following code:
