Quality of transformations¶
Key to quality¶
- poor (very lossy) - the bare minimum of metadata is preserved to allow image display, all other metadata is lost
- fair (lossy) - a portion of the metadata is preserved, at least enough to display the image and some other data, it will be far from complete however
- good - most information is preserved, it may be possible to do a better job but could be difficult for technical reasons or require custom code not just a transform
- excellent - as much information as possible is preserved, some values can still be lost if there are completely incompatible with the new schema
