JP2 and colour profile limitations: a positive conclusion and findings

At the National Library of Scotland we were finding that some colour profiles in tif files were causing errors when we tried to convert them to JP2. So a couple of weeks ago I posted a question to the DPC-Discussion list asking members for their advice on JP2 files and colour profile support.  In the end we had some great help from Johan van der Knijff, from the Koninklijke Bibliotheek (KB) in the Netherlands, who has given me permission to use a distillation of our email exchange...

Current Trends and Future Directions for Digital Imaging in Libraries and Archives

Introduction Issues of validation, compression and preservation become more important in image management as collections grow in size and complexity. On one hand compression is seen as a necessary requirement to deal with the scale of the collection on order to make preservation a practical reality, but preservation advice generally discourages compression which is seen as a preservation risk. Validation is essential for quality assurance in the development of large collections and is a...

JPEG 2000 for the Practitioner

Introduction A free seminar to explore and examine the use of JPEG 2000 in the cultural heritage industry was held at the Wellcome Trust. The seminar included specific case studies of JPEG 2000 use. It examined technical issues that have an impact on practical implementation of the format, and explored the context of how and why organisations have chosen to use JPEG 2000. Although the seminar had an emphasis on digitisation and digital libraries, the papers are relevent to a range...

DPC/BL Joint JPEG 2000 Workshop

Introduction The JPEG2000 image compression technique has been cited by experts as a new archiving format for digital images. It is both a preservation and delivery format, and has been seen as a possible alternative to the TIFF format which most institutions use as a long-term archiving standard. Produced by both imaging experts and the Joint Photographic Experts Group, it is now a recognised ISO standard. The standard JPEG file format which is so widely in use is not yet an ISO...
