Stack web interface
Stack Annotate
StackAnnotate is an add-on to the Stack web interface that allows basic drawing and text annotations to
be superimposed on the web preview window of a Delta show, and saved with the underlying frame as
a snapshot. These snapshot images can be retrieved for reference.
In essence, it is a transparent surface that accepts markers, and snapshot is a Delta web capture
recording of the show frame as seen through it.
How it works
A web capture resource is used on the DeltaGUI timeline to receive annotations from the preview web
page. The transparent annotation area is thereby placed over the currently visible show media in
playback.
The snapshot feature records the playback frame view, saves a full resolution image, and displays all
available snapshots as a thumbnail gallery. Snapshots can be redisplayed, further annotated and saved
as new snapshots.
Stack Annotate Installation
Requirements
StackAnnotate requires Delta 2.6 and Stack 1.1 build 7 or later, on the Delta Media Server. The preview
PC requires only a web browser. Chrome is installed on Delta servers, and is recommended.
Browser Support
The Stack web service aims to provide a modern and powerful web-based interface to the Delta Media
Server, using a selection of web technologies to allow advanced user interfaces and real-time feedback.
Some of these are not implemented in older web browsers. Whilst Delta Web Service may run without
major issues in older browser versions, we do not actively test these versions and do not fix bugs or
support issues that appear in them. If in doubt, use an up to date browser and version for the most
reliable performance.
Delta Server
For annotated snapshots to be saved, the Delta server running StackAnnotate needs to run in
Composition Mode, and therefore requires a Registry edit:

set 7thSense > Delta > Graphics : RenderAtCanvasRes to ‘1’.
