Currently required an application program (either in flash or other platform, what ever best implement the result)
that would allow me to take a large high-resolution image and divide into an MXN array of smaller images with a gap
specified between each image. For each resulting smaller image, pixelate to an array of PxQ squares each of one solid
color. For each pixelated smaller image, output to a file format convenient for digital printing. So basically take a large
high-resolution image and pixelate down to a specific size square, but need ability to add gaps between sub-images.
More details provided into attached .PDF file.
Its small and simple application program, only expert coder required, who implement it effective way.
