| *Title* \\ | Checking significant properties of images have been retained after migration |
| *Detailed description* | When we convert images between formats to create preservation or dissemination versions, we would like some way of checking if the conversion is successful (other than by just checking a random few by eye). Would be great if there could be a way that certain quantifiable properties of raster image files could be extracted and compared. \\
* dimensions
* number of pixels
* presence and content of metadata
This would be useful for conversions between jpg/tif/gif/png and possibly other formats too.\\ |
