Resizing a 2r structure at runtime

Question

I am processing small images in an Application. For each pixel I need to store an integer between 40 and 90. I don't know how large the image is until runtime and in a session several images may be processed. I am thinking of using a datatable because it's easy but if an image is 400X500 that means adding 400 columns and 500 rows. A 3d array or list is good but the object needs to be public and resized after an image is loaded. A matrix is a possibility too. The big issue is resizing the object at runtime. I might write it out to a temp csv file and reload it when I need it. Suggestions please.

What I have tried:

Writing it out and arrays but can't resize public arrays at runtime

Solution 1

400 x 500 = 200,000.

Using 1 byte to store the "int" (cast as a byte), your "structure" is 200KB, which in my experience is trivial.

Even if you used "int", until you get to "multi-megabyte" structures, there's nothing to be concerned about.

Program first, tune later (within reason).

Are you saying I resize a 1 D array to 200,000 at th time?

It turns out the majority of processing time is taken up by drawing the grid around the characters not processing the image. I use drawline to draw the grid first vertical then horizontal.
