I am looking for a graphics editing tool that can convert an image (photo or cartoon) into a grid (MxN) of square mono-color cells (pixels?) that when viewed from a distance will resemble the original image. Is this called "pixelating"?


I just bought a new building block toy called PinBlock. One of the things it is good at is making "pixelated" images. All of the building "blocks" are identical except for color. Each one is 3/8" x 3/8". If I could find an image processing tool that would "pixelate" an image (photo or cartoon). I could then construct that image out of PinBlocks. I think that would be a fun project to do with the grandkids.


I believe high-end tools like PhotoShop can do this, but I don't have $800 to spend just for this. I do have IrfanView. It has a Resize/Resample feature, but I haven't been able to get it to produce the result I am looking for.


For example, I have a cartoon image of Peppa Pig that IV says is 900 x 900 x 24 BPP. At 72 PPI, that's 12.5" x 12.5", which would be about 33 blocks x 33 blocks (each 3/8" wide) or 1,089 blocks in all. Each box has 1,000 blocks, so this is theoretically doable, but I'd need more that pne box to get enough of the colors I need. So I need to be able to chop this image up into a 33x33 grid where each cell in one single color that best represents the colors in that original cell (and, perhaps, the surrounding neighbors).


Here's a tutorial on YouTube by the founder that shows a simple (crude) pixelation of Iron Man.



Can anyone show me how to do this in IrfanView or suggest a different program that can do this?


I would want to be able to specify the total number of pixels so I can tradeoff the number of PinBlocks needed against the quality of the result.
