Ability for Users to Change Overlay Transparency in Neatline Exhibit

[rondauva]

Request for new functionality, via user kteach (k12 teacher) on the Omeka forum:

A slider of some sort that allows a user to adjust the transparency of an overlaid Neatline item to see the base layer underneath. Useful for comparing locations/time in works of literature.

Her use case summary:
"it would be great for my students to be able to more easily look at the contemporary maps underneath the historic maps as they navigate the site. I think that they would be interested in noticing the way that the authors freely mix real street addresses & landmarks with imaginary ones as well as getting a sense of the distances involved in some of the character’s travels given they were often moving by foot. So if they started with a map with various locations marked, they could slide the transparency to reveal which locations are real (and still exist) and which came from the author’s historical research and/or imagination. Also which areas of these cities demonstrate the same racial housing patterns as a century or more ago."
