Utilities for processing uploads.
|
|
|
|
Processors have 3 methods available:
|
|
|
|
- process/3:
|
|
Takes an analysis, file path, and version list and generates an
|
|
"edit script" that represents how to store this file according to the
|
|
given version list. See Philomena.Images.Thumbnailer for more
|
|
information on how this works.
|
|
|
|
- post_process/2:
|
|
Takes an analysis and file path and performs optimizations on the
|
|
upload. See Philomena.Images.Thumbnailer for more information on how this
|
|
works.
|
|
|
|
- intensities/2:
|
|
Takes an analysis and file path and generates an intensities map
|
|
appropriate for use by Philomena.DuplicateReports.
