gis-l: RE: scale dependable transparency

[Kekelis, Gary]

Great idea, Jorge! I wish ArcMap would do that out of the box. It would be a good feature to suggest to them.

However, I could allow transparency to vary based on scale automatically in the new Map Direct Lite.


Jorge - for Map Direct, given the choice, would you prefer the scale dependent transparency, or would you prefer the fill to go to hatch at some scale and then go empty at another scale?


Currently in Map Direct, I created a feature that allows you to turn polygon fills on and off, which solves the problem to some extent and is very flexible, but requires user interaction. I want to improve this in the new Map Direct Lite to provide some kind of automatic scale dependent rendering to handle the case you mentioned below.

Check out THIS POST<http://gis.stackexchange.com/questions/14476/changing-symbology-as-per-scale-reference-in-arcmap> one of the comments brings up representations as an option also one answer mentions using ArcObjects, I think your work around with the duplicate layer may be the easiest though.

Subject: gis-l: scale dependable transparency

I wonder if it is possible at all to set transparency levels based on the scale. I thought I was overlooking something very simple but perhaps it is not that simple since I am still trying to figure out scale dependable transparency.

Essentially, I want to have a polygon showing  solid from far away but 10% transparent when zoomed close in.

Currently, I have to add the layer twice and apply one scale for the solid and the opposite for the hollow (or  10% transparency)

Thanks for any input.
