In the above example, I've restricted the largest square plate to 6圆 anyway. It supports plates up to 16x16 in size, but those are only available in a few colours. There's no interactivity yet, and I'm not sure there will be, as I only wrote it to produce a layout for myself (it's surprising how productive you can be when you haven't got an internet connection for an evening.) Another nice function would be if it could spit out a parts list of all the pieces in their desired it's still a work in progress, but I've fully automated the process of turning a photo or other image into a reduced colour version, using either all Lego colours, greyscales, or just whatever colours are readily available from the Lego shop. What I like with yours already out of the gate, is that the sections have division lines between the plates. You should give it a spin to see how your app compares in functionality. So will need to use a different app if you want to make a bigger or smaller sized one. The other restraint is that it is confined to the default grid size I used. It also allows you to choose the type of color scheme of the mosaic, to a limited point. I'm not familiar with what a 'PNG' version means? I used the iPhone app named Lego Photo to convert the normal pic. Definitely wasn't the cost efficient way to do it, but now I know better for the future. I did this as my first MOC before I learned how to use Bricklink, so parts were gathered by breaking up Creator sets like Highway Transport or Prehistoric Hunters. ^^Thanks I was only able to use large plates for the black sections, but most other colors & areas had to use small sized plates like 2x2 corners, 1x3, 1x1, etc.
