About the notecards
There are two notecards for this HUD that will not appear in the drop-down menu for loading notecards: .help (this one) and .config. DO NOT REMOVE THESE - particularly the .config as you will need it to set the channel so that the HUD and the Image Display Screen can communicate. There is also a configuration notecard for the Image Display Screen, and again, it must not be removed or the screen will not function.
.config notecard
This is a simple notecard in the Contents tab of the HUD containing the following:
# Configuration notecard for "Black Tulip Presenter" # Lines beginning with # are ignored # If ProjectorChannel is set to 0, please change it (preferably to a negative integer value) # Don't forget to set the same value in the Image Display Screen. The script inside the Image # Display Screen says in its comments where to change it. ProjectorChannel = -6728 ChatReceiverChannel = 3 PassPhrase = this iS An exAMple of passPHRASE to ENCODE UUIds to send the viEWeR
The purpose of these parameters is as follows:
ProjectorChannel: This is the channel for communication between the HUD and the Image Display Screen to display the images you have named in your presentation notecard (see below). Change the -6728 to another integer number - any number other than 0 (preferably a large negative integer). Then edit the Image Display Screen (rezz) object and open the .config notecard in the contents tab and change the number next to ProjectorChannel = to match the number here.
ChatReceiverChannel: This is the channel that accepts ad hoc chat input from the presenter, so that it can be displayed in green in local chat. We recommend that you set it to some small, easy-to-remember value (e.g. 66, or perhaps your birth year ;-) )
PassPhrase: This is a password used to encrypt the UUIDs of images and sounds that are sent to the Image Display Screen. This is done so if anybody has a chat listener, it doesn't matter that it intercepts the message. They will not be able to intercept the texture or sound UUID if they don't have this master password. You can change this as desired – the longer the pass phrase, the better. This must match the PassPhrase specified in the configuration notecard of the Image Display Screen.
.slideReceiver.config notecard
This is a simple notecard in the Contents tab of the Image Display Screen containing the following:
# Configuration notecard for the Image Display Screen accompanying the "Black Tulip Presenter"
# Lines beginning with # are ignored
# If ProjectorChannel is set to 0, please, change it (preferably to a negative integer value)
ProjectorChannel = -6728
BaseSize = 8
AspectRatio = 1:1
PassPhrase = this iS An exAMple of passPHRASE to ENCODE UUIds to send the viEWeR
The purpose of these parameters is as follows:
ProjectorChannel: This is the channel for communication between the HUD and the Image Display Screen to display the images you have named in your presentation notecard (see below). Change the 0 to another integer number - any number other than 0 (preferably a large negative integer). This should normally match the value in the .config notecard of the HUD for your primary display screen. However, you can configure another Image Display Screen to a different channel, and then send images to that screen by including its channel number in the commands in your Presentation Notecard. See "Projecting an Image" below for an example.
BaseSize: This is the width (in meters) of the Image Display Screen when you rez it.
AspectRatio: This is the aspect ratio of the Image Display Screen when you rez it.
PassPhrase: This is a password used to encrypt the UUIDs of images and sounds that are sent to the Image Display Screen. This is done so if anybody has a chat listener, it doesn't matter that it gets the message. They will not be able to intercept the texture or sound UUID if they don't have this master password. You can change this as desired – the longer the pass phrase, the better. This must match the PassPhrase specified in the configuration notecard of the HUD.
