SymmetryMill snapshots are essentially concise recipes for creating patterns
from a source image. They do not contain any information about actual pixel
content (other than thumbnail icons in the
Snapshots panel). You can therefore edit
your source image in any application of your choice and re-build patterns
saved as snapshots, simply by re-loading the image in SymmetryMill.
When editing images, preserve the image (canvas) size so that SymmetryMill
could re-apply your recipes correctly.
You can similarly apply the same snapshots to completely different images.
Note: To apply the saved snapshots to an edited image, the image must have the
same file name (if loaded by browsing your local computer) or be stored at
the same location (if loaded by web address).
