CHAPTER 1
Extending Fireworks
Overview
To extend Macromedia Fireworks 8, you must write JavaScript code. You can use JavaScript to
write your own objects and commands that affect Fireworks documents and the elements
within them. To accomplish these tasks, you must be proficient in JavaScript and
in Fireworks.
This guide introduces the Fireworks Object Model, explains how to write cross-product
extensions (extensions written in, or for, other Macromedia applications), and discusses the
JavaScript Auto Shape construction. The final chapter is a reference to the Fireworks
JavaScript application programming interface (API)—the custom JavaScript functions that
are built into Fireworks.
Prerequisites
Because Fireworks extensions must be written in JavaScript, this guide assumes that readers
are familiar with JavaScript syntax and with basic programming concepts such as functions,
arguments, and data types. It also assumes that readers understand the concept of working
with objects and properties. This guide does not attempt to teach programming in general or
JavaScript in particular.
Anyone who wants to extend Fireworks should have a good JavaScript reference to help with
syntax questions (for example, is it substring() or subString()?). Useful JavaScript
references include JavaScript Bible by Danny Goodman (IDG), JavaScript: The Definitive
Guide by David Flanagan (O’Reilly), and Pure JavaScript by R. Allen Wyke, Jason D. Gilliam,
and Charlton Ting (Sams).

6 Extending Fireworks Overview
Installing an extension
As you start learning the process of writing extensions, you might want to explore the
extensions and resources already available through the Macromedia Exchange website
(www.macromedia.com/exchange). By installing an existing extension, you will become
familiar with some of the tools that you need to work with your own extensions.
To install an extension:
1. Download and install the Extension Manager, which is available on the Macromedia
Downloads website (www.macromedia.com/software/downloads).
2. Log on to the Macromedia Exchange website (www.macromedia.com/exchange).
3. Click the Fireworks Exchange link.
4. From the available extensions, choose one that you want to use. Click the Download link
to download the extension package.
5. Save the extension package in a directory on your machine.
6. In Fireworks, choose Commands > Manage Extensions to start the Extension Manager (or
you can start Extension Manager, located in the Macromedia program group,
independently from Fireworks).
7. In the Extension Manager, choose File > Install Extension, and choose the extension
package you just saved.
The Extension Manager automatically installs the extension into Fireworks.
You cannot begin using some extensions until you restart Fireworks. If you are running
Fireworks when you install the extension, you might be prompted to quit and restart
the application.
To view basic information on the extension after its installation, go to the Extension Manager
(Commands > Manage Extensions) in Fireworks.
What’s new in Extending Fireworks 8
Fireworks 8 includes the following new features and interfaces that you can use to develop
extensions for the product:
Marquee-to-path and path-to-marquee conversions In Fireworks 8 you can convert
marquees drawn with any of the marquee tools to a vector path. You can also convert any
vector path to a marquee and set its edge to hard, anti-aliased, or feathered.

Conventions used in this guide 7
Vector path compatibility with Macromedia FreeHand Although Fireworks 8 imports
winding fills from FreeHand MX, it does not provide a user interface that lets you create a
winding fill. However, Fireworks 8 has APIs that let third-party developers create an interface
where a user can specify if a path uses an even/odd or winding fill.
Lock individual objects within a layer Instead of having to create a new layer specifically
for an object you want to lock, Fireworks 8 lets you lock specific objects on a layer without
locking the other objects on the same layer. Three new APIs let you specify which object to
lock.
New panels and commands Fireworks 8 introduces three new panels and a new
command. Several new APIs let you set selections within these panels and access the new
command.
Access dialog boxes Fireworks 8 introduces a new Dialogs class as a property of the
Fireworks object. The APIs in this class let you run standard application dialog boxes that are
usually accessible only through the menu.
Get system information The new System class in Fireworks 8 provides APIs that let you
query for information about the operating system.
Conventions used in this guide
The following typographical conventions are used in this guide:
■Code font indicates code fragments and API literals, including class names, method
names, function names, type names, scripts, SQL statements, and HTML and XML tag
and attribute names.
■Italic code font indicates replaceable items in code.
■The continuation symbol (¬) indicates that a long line of code has been broken across two
or more lines to fit on the page. When copying the lines of code, eliminate the
continuation symbol and type the code as one line.
■Curly braces ({ }) around a function argument indicate that the argument is optional.
The following naming conventions are used in this guide:
■You refers to the developer who is responsible for writing extensions.
■The user refers to the person using Fireworks.
■The visitor refers to the person who views the graphic that the user created.

CHAPTER 2
The Fireworks Object Model
If you want to extend the functionality of Macromedia Fireworks 8 by writing or modifying a
JavaScript extensibility file, you must become familiar with the objects that Fireworks makes
available through JavaScript. The hierarchy of these objects comprises the Fireworks Object
Model, which contains the following major components:
■Six global methods that are available from any part of the application and need not be
declared as methods of a particular object. For more information, see “Global methods”
on page 12.
■Six core objects: Dialogs, Document, Errors, Files, Find, and System. For more
information, see “Core objects” on page 13. (The App object that was used in Fireworks 3
is supported for backward compatibility, but its use is deprecated in favor of the Fireworks
object.)
■The Fireworks object (for more information, see “The Fireworks object” on page 26).
■Numerous objects associated with Fireworks documents, such as ExportOptions, Guides,
Path, Image, and Text. For more information, see “Objects within Fireworks documents”
on page 32.
■A set of objects that you can use to specify the format of HTML code when exporting
from Fireworks. For more information, see “HTML export objects” on page 80.
Using the Fireworks Object Model
When scripting extensions for Fireworks, you write JavaScript commands that send calls to
the Fireworks Object Model to determine or change the current settings for a Fireworks
document. For example, the following command calls the Fireworks object (fw) to obtain the
path to the Export Settings directory (appExportSettingsDir), which is expressed as a file:/
/URL. In other words, fw references the Fireworks global object, of which
appExportSettingsDir is a property (for more information, see “The Fireworks object”
on page 26), so a JavaScript command can assign the resulting value to a variable, as follows:
var expSetDir = fw.appExportSettingsDir;

10 The Fireworks Object Model
Accessing a Fireworks document
All the functions listed in “Document functions” on page 132 are methods of the Document
object, which represents a Fireworks document. To perform a function on a Document
object, you must first get the Document Object Model (DOM) of the document. You then
call the functions as methods of that DOM.
■To use a DOM function with a document other than the active document, use the
following syntax; note that documentIndex is a zero-based index that specifies which
document the command will affect.
fw.documents[documentIndex].functionName();
■To use a DOM function with the active document, use
fw.getDocumentDOM().functionName() (for more information, see
fw.getDocumentDOM()).
Passing values
For all properties that are not read-only, you can pass values to change elements of a
document. For example, the following command sets the fifth brush in the third open
document to a square shape:
fw.documents[2].brushes[4].shape = "square";
The preceding example includes the following properties:
■documents is a property of the Fireworks object and contains an array of
Document objects.
■brushes is a property of the Document object and contains an array of Brush objects.
■shape is a property of the Brush object.
Fireworks Object Model calls and API calls
In some cases, you can use Fireworks Object Model calls or API calls to perform the same
operations. In other cases, a certain function might be available in either the Fireworks Object
Model or the API, but not in both.
NOTE
You can use methods that operate on a document’s DOM only on open documents.
NOTE
Throughout this manual, optional arguments are enclosed in {braces}.

Using the Fireworks Object Model 11
For example, if the first open document is the current document, the first code fragment has
the same effect as the second and third code fragments. The fw.getDocumentDOM() function
references the current document (for more information, see “Accessing a Fireworks
document” on page 10).
fw.getDocumentDOM().setDocumentResolution({pixelsPerUnit:72, units:"inch"})
;
fw.documents[0].resolution =72;
fw.documents[0].resolutionUnits ="inch";
Formatting nonstandard data types
In addition to the standard data types that can be passed to functions as arguments, or used as
properties, such as integer, string, and so on, Fireworks accepts other data types.
■Some functions accept values that are Fireworks objects. For more information, see “The
Fireworks Object Model” on page 9.
■Some functions accept a string in a specific format. Others accept value types that are not
Fireworks objects but are JavaScript object types that are specific to Fireworks. These types
of arguments are described next, in alphabetical order.
Color string data type
Functions that accept colors as arguments use the HTML syntax "#rrggbb". You can
specify a color with an alpha (transparency) component by passing a longer string of the
form "#rrggbbaa".
Mask data type
The format for a mask is {maskBounds: rectangle, maskKind: string, maskEdgeMode:
string, featherAmount: int, maskData: hex-string}.
■maskBounds specifies the bounding rectangle of the mask area.
■Acceptable values for maskKind are "rectangle", "oval", "zlib compressed",
"rle compressed", or "uncompressed".
■If the value of maskKind is "rectangle"or "oval", the maskData string is ignored, and a
mask of the right shape is constructed that fills maskBounds and that has the edge
specified by maskEdgeMode and featherAmount.
■If the value of maskKind is "zlib compressed", "rle compressed", or
"uncompressed", the maskData string is presumed to contain 8-bit mask data in
hexadecimal format that precisely matches the maskBounds to define the mask.

12 The Fireworks Object Model
Matrix data type
The format for a matrix is {matrix:[float, float, float, float, float, float,
float, float, float]}. This guide assumes that you know how to use these nine values to
construct a three-by-three transformation matrix; discussion of the construction of
transformation matrices is beyond the scope of this manual.
Point data type
The format for a point is {x: float,y: float}. For instance,
dom.addNewLine(startPoint, endPoint)could look like the following example:
fw.getDocumentDOM().addNewLine({x:64.5, y:279.5}, {x:393.5, y:421.5});
Rectangle data type
The format for a rectangle is {left: float, top: float, right: float, bottom:
float}. For instance, dom.addNewOval(boundingRectangle)could look like the following
example:
fw.getDocumentDOM().addNewOval({left:72, top:79, right:236, bottom:228});
Resolution data type
The format for resolution is {pixelsPerUnit: float, units: string}. Acceptable values
for units are "inch" or "cm". For instance, dom.setDocumentResolution(resolution)could
look like the following example:
fw.getDocumentDOM().setDocumentResolution({pixelsPerUnit:72, units:"inch"})
;
Global methods
The following table lists the global Fireworks methods, along with their argument data types
and, where appropriate, acceptable values and notes.
Method Data type Notes
alert(message) string Displays a string in a modal alert box, along
with an OK button. Returns nothing.
confirm(message) string Displays a string in a modal alert box, along
with OK and Cancel buttons. Returns true
if OK is clicked, false if Cancel is clicked.

Core objects 13
Core objects
This section describes the six core objects that are always available: Dialogs, Document,
Errors, Files, Find, and System.
Dialogs object
The following table lists the methods of the Dialogs object, along with their data types and,
where appropriate, acceptable values and notes.
prompt(caption, text)string, string Prompts the user (with the string that is
specified by text) to enter a string in a
modal dialog box; the dialog box is titled
with the string that is specified by caption.
Returns the string entered if OK is clicked,
null if Cancel is clicked.
write(arg1, arg2, ..., argN)string Same as WRITE_HTML; WRITE_HTML was
created to let you differentiate HTML
output calls from other JavaScript calls in
your code.
WRITE_CSS string Available only when exporting. Writes the
CSS as an external file.
WRITE_HTML(arg1, arg2, ...,
argN)
string Available only when exporting. Converts
each argument to a string and writes it to
the HTML output file. To enter an end-of-
line character, use "\n"; this is converted to
the correct line ending for your platform.
For more information, see “HTML export
objects” on page 80.
NOTE
For information on how to format nonstandard data types, such as rectangle or point,
see “Formatting nonstandard data types” on page 11.
Method Data type Notes
runEditGrids() none Opens the Edit Grids dialog box.
runEditGuides() none Opens the Edit Guides dialog box.
runNumericTransform() none Opens the Numeric Transform dialog box.

“Guides object” on page 67).
Property Data type Notes

16 The Fireworks Object Model
height integer Total height of the document, in pixels.
To find the bottom edge of the document,
use document.
top + document.height.
isDirty Boolean Set to true if the document was modified
since the last ti me it was saved.
isPaintMode • Boolean Set to true if the document is currently in
paint-mode editing, false otherwise.
isSymbolDocument • Boolean Set to true if the document is a Symbol or
Button document, false if it is an ordinary
document. You might see this when looking
through the list of open documents and one
is a symbol-editing window.
isValid Boolean Set to true if the document is open in
Fireworks; false otherwise. (Occasionally
the JavaScript object that is associated
with a document lingers after the document
closes; this property lets you check for
that eventuality.)
lastExportDirectory string The path to the last directory to which the
file was exported, which is expressed as
file://URL, or null if the file was never
exported. For instance, if the document
was last exported to "file:///files/
current/logo.gif", it returns "file:///
files/current".
lastExportFile string The name that was used the last time the
file was exported, or null if the file was
never exported. For instance, if the
document was last exported to "file:///
files/current/logo.gif", it returns
"logo.gif".
layers • array An array of Layer objects in the document
(for more information, see “Layer object”
on page 67).

useMatteColor property.
onionSkinAfter integer Number of frames after the current frame to
show through onion skinning. Corresponds
to the onion-skin controls in the left edge of
the Frames panel. A value of 0indicates no
onion skinning; a very large value (such as
99,999) indicates onion skinning of all
frames after the current frame.
onionSkinBefore integer Similar to the onionSkinAfter property,
but refers to the number of frames to show
through onion skinning before the
current frame.
patterns • object List of internal pattern names.
pathAttributes object PathAttrs object (for more information, see
“PathAttrs object” on page 68). This object
specifies default attributes that will be
applied to all newly created objects.

various chunks of text in a well-known
format. For more information, see “The
pngText object” on page 18.
resolution float Document resolution, in pixels per unit (for
more information, see resolutionUnits).
The range is 1 to 5000.
resolutionUnits string The units to be used with the resolution
property. Acceptable values are "inch"
and "cm".

active document.
Property Data type Notes

18 The Fireworks Object Model
The pngText object
Fireworks maintains the following fields for use with the pngText object:
You can edit these or add your own fields, and they will be preserved across file saves.
The pngText object corresponds directly to the 'tEXt' chunk of the document’s PNG
structure.
Errors object
All Errors object properties are read-only strings that are used to simplify the localizing of
scripts. They return localized error messages appropriate to the specific error. For example, the
English version of Fireworks returns "Memory is full." for the EOutOfMem property.
textures array Array of Texture objects that are available
for use in the document (for more
information, see “Texture object”
on page 56).
top integer Coordinate of the top edge of the
document, in pixels. To find the bottom
edge of the document, use
document.top + document.height.
useMatteColor Boolean If set to true, the matteColor property is
used when exporting documents with
transparent backgrounds. If set to false,
the matteColor property is ignored in this
situation, and the exported file is matted
against the document’s canvas color.
width integer The width of the document, in pixels. To
find the right edge of the document, use
document.left + document.width.
Field name Value
CreationTime The date and time the document was created.
Software The software used to create the document. The current version of
Fireworks always sets this value to “Macromedia Fireworks 8.”
Property Data type Notes

Files object
The following table lists the methods of the Files object, along with their data types and,
where appropriate, acceptable values and notes.
Method Data type Notes
copy(docname1, docname2)string, string Copies the file specified in the first
argument to the file specified in the
second argument. Each argument must
be the name of a file, which is expressed
as file://URL. Only files (not directories)
can be copied. The files do not need to
reside on the same drive, and the
method does not overwrite a file if it
already exists. Returns a value of true if
the copy is successful; false otherwise.
createDirectory(dirname) string Creates the specified directory. Returns
true if successful; false otherwise.
createFile(fileURL, fileType,
fileCreator)
string, string,
string
Creates the specified file. The file must
not already exist. The first argument is
the name of the file, which is expressed
as file://URL. The last two arguments let
you specify the file type and file creator
strings. The fileType and fileCreator
strings should each be strings of exactly
four characters in length, for example:
Files.createFile(newFile,".txt","FWM
X");

20 The Fireworks Object Model
deleteFile(docOrDir) string Deletes the specified file or directory.
Returns true if successful; false if the
file or directory does not exist or cannot
be deleted. Compare with
deleteFileIfExisting().
deleteFileIfExisting (docOrDir) string Deletes the specified file or directory.
Returns true if successful; false if the
file or directory cannot be deleted.
Unlike deleteFile(), this method
returns true if the file or directory does
not exist.
enumFiles(docOrDir) string Returns an array of file URLs. If
docOrDir is a directory, the array
contains an entry for every file or
directory that is contained in
the specified directory. If docOrDir is a
file, the array contains a single entry
(the file passed in).
exists(docOrDir) string Returns true if docOrDir refers to a
directory or file that exists; false
otherwise.
getDirectory(docname) string Returns only the directory name from
docname, which is expressed as file://
URL. For example,
Files.getDirectory("file://work/
logo.png") returns "file:///work".
getExtension(docname) string Returns the filename extension, if any,
of docname. For example,
Files.getExtension("birthday.png")
returns ".png". If the filename has no
extension, an empty string is returned. A
filename that is expressed as file://URL
is acceptable.
getFilename(docname) string Returns just the filename from docname,
which is expressed as file://URL. For
example, Files.getFilename("file:///
work/logo.png") returns "logo.png".
getLanguageDirectory() string Returns the URL of the language
directory associated with the currently
running language.
