Many Keléstia Productions products — the numerous Atlas Keléstia squares, the Hârn and Shôrkýnè regional interactive map, and the Chélemby City interactive map — include "layered" PDF files, which allow the user to select which layers of information to display. A few customers have asked how this function works. Read on to find out more.
In most cases, when each of these files is opened, a given selection of layers is pre-set for display. However, users can select which combination of layers they wish to display, so that, for instance, a GM can produce their own player maps which omits "hidden" information.
This functionality is accessed via the "layers" panel in Adobe Acrobat and Adobe Reader versions 7 and later. This is located down the left-hand side of the display window and can be accessed via the "stack" symbol.
Once the Layers panel is open, users can select which layers are shown by toggling on/off the "eye" symbols shown next to each layer name. Attached is an image of the Hârn Interactive PDF map with the layers panel open, which we hope will help users access the function:
Please note: Some PDF display programs, such as Apple's Preview, do not allow the user to choose which layers in a multi-layered PDF to show.
