Image Display: Image zooming

People have brought the problem up many times that it would be better if we could display images dynamically and be able to zoom in.

A quick and easy solution is Zoomify EZ (which is free) or other more expensive versions of Zoomify that have more features.

Zoomify will work with high resolution images relatively quickly. It works by saving the image in a mosaic of smaller images at different resolutions. It only deals with a few sections of the image at a time instead of dealing with the whole image, so there is very little lag. The speed is determined more by the computer and the internet connection than the size of the image itself.

With this software, the level of zoom is determined by the DPI of the image. It will allow someone to zoom in till the section they are viewing has reached the original DPI.
Since the free version of Zoomify uses flash, it also helps to prevent people from downloading the image. This can be a problem if your goal is to share the pictures. You will have to include a link to the original image to allow people to download it easily.

Zoomify can also work with Photoshop and there are many resources on-line discussing how:

Atiz scanner and Kirtas scanner aren’t playing nice with eachother

I love the Atiz scanner for it's simplicity, good design, and utility. I love the Kirtas scanners for their speed and their "wow" factor when people see the things work. The only problem I have at the moment is taking our current Kirtas workflow (using Kirtas's software Bookscan Editor, Superbatch, and OCR manager), and finding a way to make the Atiz scanner workflow work with it. The Atiz machine came with a hefty batch editing program that does a great job of cleaning up the images and making them wonderfully presentable. The machine even came with a PDF maker, but it doesn't OCR on its own, and it doesn't give you the options that Kirtas' OCR manager do. So, I want to process the Atiz scanner finished images using Kirtas’s OCR manager. However, that seems to be more difficult than I had first expected. For the next month, I’ll be trying to figure out how to make this marriage of Atiz and Kirtas systems work. If it ends up failing, then I may have t...

Ex Libris Digital Preservation system

Today I attended a webinar from Sun Microsystems about the new Ex Libris Digital Preservation system. You can view the webinar here . The talking points are they handle all the hardware and they can handle the software. They claim it’s secure and built with redundancy. The major problem is that they say you can’t provide access to the files without getting Primo (Ex Libris’s new Amazon-like catalog toy-which is looking fun). They won’t convert the files for you when the formats out of style, but they make it so that you can maintain and upgrade the files. All and all, I like the idea of a comprehensive digital preservation system being handled by people who know hardware. I Just think it is going to be too expensive for most libraries. Time will tell how many libraries pick this up.

Microfilm and Microfiche scanners

I have been researching high speed microfiche and microfilm scanners for the last year. There are four major companies that produce microform scanners. Mekel (a Crowley Company), Wicks and Wilson , nextScan ,and Sunrise . They each have their advantages and disadvantages. Both nextScan and Sunrise have 3-in-1 or 2-in-1 models, where you have one machine (~$100,000) that comes with one attachment, and you buy other attachments for different types of microform (Microfilm, Microfiche, and Aperture card). Each attachment costs extra. I never figured out the cost for the attachments. nextScan also has a dedicated roll film scanner , that I’ve heard good reviews from the Newspaper Digitization Project in Australia . In general, I have heard that the 3-in-1 or 2-in-1 machines are fine, but they tend to go slower than dedicated machines. They really are built for versatility and marketed toward libraries who can only afford one machine that can do all types (Paying $100,000+ for one...
