Working with Snapshots: Advanced Use of Snapshots

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).
