Global Variables
This
chapter describes the Turbine Variables that have a special meaning
inside the Turbine engine.
Media
and System Global Variables
Turbine
includes two automatically defined families of variables that contain
contextual information about the media being generated, as well as a
number of system settings and defaults - the Media and System variable
families:
Media:
| Variable |
Description |
Example |
| {Media.Width} |
The
output native Width in pixels |
550 |
| {Media.Height} |
The
output native Height in pixels |
400 |
| {Media.FrameRate} |
The
number of frames per second |
12 |
| {Media.Color} |
The
native background color to be output |
#FFFFFF |
| {Media.NumFrames} |
Total
number of frames |
20 |
| {Media.Flash.Version} |
The
numeric version to use when generating Flash |
6 |
| {Media.Debug} |
A
boolean value that specifies whether the Turbine Window will be
included on the generated media. On Flash, also defines if a native
debug tag will be emitted, allowing the movie to be debugged on
the browser/Flash editor |
Yes |
| {Media.Protect} |
Whether
the output media will be protected - for example when generating
Flash this means the "protect from import" flag |
No |
| {Media.Compress} |
If
non-zero, specifies the level of output compression, from 1 to 9,
with 9 being the best compression. If 0 or "No", no compression
is applied. On Flash, applies Flash 6+ compression to the generated
movie |
9 |
| {Media.Script} |
The
complete URL path to the executed ASP.NET script |
/turbine/script.aspx |
| {Media.Query} |
The
QUERY_STRING used to call the script |
person=Mathilda |
| {Media.Location} |
The
path and query string used to request this script - very useful
for self-referencing |
/turbine/script.aspx?
person=Mathilda |
| {Movie.Self} |
The
path and query string used to request this script, for use with
the GenerateHTMLFirst command, for self-referencing |
/turbine/script.aspx?
person=Mathilda&
_media |
Media.PDF:
When generating
Adobe PDF documents, Turbine also uses these variables:
| Variable |
Description |
Example |
| {Media.PDF.Version} |
The
numeric PDF version to use when generating PDF.
For Acrobat PDF viewer 6, use 5, for Acrobat PDF viewer 5 use 4
and so on. Default is version 2, requiring Acrobat PDF viewer 3. |
2 |
| {Media.PDF.Title} |
The
title of the PDF document. Visible in the document properties |
My
Title |
| {Media.PDF.Subject} |
The
subject of the PDF document. Visible in the document properties |
My
Subject |
| {Media.PDF.Author} |
The
author of the PDF document. Visible in the document properties |
My
Name |
| {Media.PDF.UserPassword} |
When
defined causes the PDF document to be encrypted. The user must provide
this password in order to open it |
MyPassword |
| {Media.PDF.OwnerPassword} |
When
defined causes the PDF document contents to be encrypted |
MyPassword |
| {Media.PDF.Permissions} |
PDF
document permissions, a combination of:
noPrinting - the PDF user can't print the document
noChanging - the PDF user can't change the document
noContentCopying - the user can't copy the document contents
noCommenting - the user can't comment the document.
This
variable only has any effect if the PDF document is encrypted.
To encrypt a PDF document set {Media.PDF.UserPassword} or {Media.PDF.OwnerPassword} |
noPrinting |
System:
Default
values for System variables are read from the system.settings file on
the Turbine installation directory (or on the bin/ directory of the
Web Application if used without installation) - this file is read during
application load time.
The following System variables are defined:
| Variable |

log level, a combination of:
errors - log errors
warnings - log warnings
info - log information messages |
errors,
warnings |

to log into, a combination of:
media - log into the Turbine Window
file - log to the turbine.log file |
media |
| {System.Debug} |
The
default value to use in the {Media.Debug}, if not specified by user |
No |
| {System.Protect} |
The
default value to use in the {Media.Protect} variable, if not specified |

by 20 - for example a 20 pixel font size should be specified here
as
20 * 20 = 400 |
400 |
| {System.FontColor} |
The
default text color to use when not specified in a <Text> tag |
