The samples in the slideshow below show 15 of the 17 symmetry groups, where you can export a rectangular tile. Below this gallery, I will explain how to use this tile in Photoshop to create large scale files for canvas or paper prints.
Filling a large surface with your KaleidoPaint tile using Photoshop.
This is a quick method of plane filling. A plane, as in a large two dimensional surface, like one that you would use to create the file for a high quality print, where you need a high pixel resolution.
- Export the tile from you KaleidoPaint drawing using the new menu option. Only 15 of the 17 symmetry groups can be tiled in a perfectly square group.
- Go to your photos folder and email that tile to yourself.
- Open the tile in Photoshop. Note the tile’s dimensions in pixel width and height. Here 1906×1100.
- Decide how large a canvas you want, possibly in multiples of your tile’s dimension. 300 dpi is a good resolution for large paper prints. Let’s choose 6000 x 4000 pixels for our file.
- Place the first tile in the upper left, flush top and side
- CTRL/CMD-J is the key combination to duplicate the layer
- Select this layer then pull up the offset filter, way at the bottom of the list under “other”
- For the first operation, do the horizontal repeats, the slide number should be the width of your tile, 1906 pixels for our example, the vertical will stay at zero for now
- Apply the filter. The offset filter moves this layer the exact number of pixels you’ve entered
- CTRL/CMD-J again to duplicate this new shifted tile layer
- Repeat the filter on the new layer and continue till you reach the other edge (latest filter shows up at the top) The operation becomes a dance of CTRL-J then CTRL-F till you reach the right edge of your canvas.
- Select this series of layers and merge them
- Duplicate this strip of tiles
- Go to the full offset menu, not the shortcut key, horizontal should be zero, vertical should be 1100, the height of the tile
- Apply the offset filter, duplicate the layer and repeat the filter, till you reach the bottom, again, dancing with your shortcut keys, CTRL-J then CTRL-F.
- Flatten the image and you’re done!
- The other two radical symmetry groups that do not conform to this exact method of tiling are P1 and P2. They will give you a rectangle as well, but in order to line up the design, you must figure out the horizontal offset to the tile.
