SWF::Movie(3) User Contributed Perl Documentation SWF::Movie(3)NAME
SWF::Movie - SWF Movie class
SYNOPSIS
use SWF::Movie;
$m = new SWF::Movie();
$m = SWF::Movie::newSWFMovieWithVersion(8);
DESCRIPTION
SWF::Movie is the root object of your flashfile. It contains all your
other objects you want in your movie. Ming supports many Flash4,
Flash5 F6,7,8,9.. features.
The SWF::Movie object contains information like the flashversion, the
size, the frames per second, the background color. Except that, the
SWF::Movie behaves like a SWF::MovieClip. It only cannot be added to
another SWF::Movie or SWF::MovieClip.
Notice: The version of your flashmovie can be set by the object SWF.
See SWF for more details.
METHODS
$m = new SWF::Movie()
Creates a Movie object.
$m = newSWFMovieWithVersion(version)
Creates a Movie object with version value (e.g. 8) set.
$displayItem=$m->add($SWFObject)
Add an instance of a SWF-object to your current frame. The
returnvalue is a SWF::DisplayItem.
Some possible SWF-objects are:
SWF::Action
SWF::MovieClip
SWF::Shape
SWF::Sound
SWF::Text
SWF::TextField
SWF::Bitmap
SWF::PrebuiltClip
$m->add($shape); # possible, but not more accessible for us
$shape_1 = m->add($shape); # good instance
$m->addExport($block, $name)
Prepare linkage to Action script code.
$m->addExport($mc, 'mc');
# and later inside action script....:
$ac = new SWF::Action("_root.attachMovie('mc','mc1',11);");
$m->writeExports()
Export prepared names to Action script.
remove($displayItem)
Removes the given SWF::DisplayItem instance from the current and
following frames of the main timeline.
$m->remove($shape_i);
nextFrame()
Finish a frame of the main timeline. New added objects will be
added in the next frame.
$m->nextFrame();
setNumberOfFrames($frames) =item setFrames($frames)
Preset the number of frames of the main timeline. n not used frames
before finishing the movie will filled with n nextFrame()
statements. If you inserted more nextFrame() commands than you set
with setFrames() the setFrames() will be ignored.
$m->setFrames(100);
$m->setBackground($red,$green,$blue)
Set the background in red, green, blue values. Possible value are
0..255 or hexvalues 0x0..0xff.
$m-setBackground(0xff,0x99,0x00); # orange bg
$m-setBackground(0,200,255) # green bg
A transparency level isn't available I asume. (In Flash MX/F6?). A
transparent background can be set in the HTML-code for Internet
Explorer. Please inform the Authors if that is available for nonIE-
browsers.
$m->namedAnchor($label)
This function adds a named anchor to the movie.
$m->setDimension(x,y)
Set the dimension in pixel.
#ToDo:
#min: (0.0,0.0) # ;-)
#max: (?,?)
#default: (0.0?,0.0?)
#Behavior when values <min: ming sets it to min
#Behavior when values >max: ming sets it to max
$m->setDimension(200,100);
$m->setDimension(123.45,67.89);
$m->setRate(int)
Set the playing speed in frames/second.
#ToDo:
#min: 0
#max: ?
#default: ?
#Behavior when value <min: ming sets it to min
#Behavior when value >max: ming sets it to max
$m->setRate(30);
$m->protect()
A feature that prevents only flashnewbies from importing your movie
into Macromedias Flash authoring tools. It cannot protect your
content from being loaded by other flashmovies, deleting of the
protection with a hexeditor or disassembling with tools.
$m->setSoundStream($soundstream, [$skip])
Puts an SWF::SoundStream object as streaming sound into the main
timeline. The optional skip parameter describes the time in
seconds to be skiped.
$m->setSoundStream($soundstream);
$m->streamMp3($filename)
Simplifies the setSoundStream(). You only need the filename.
$m->streamMp3("iloveyou.mp3");
Hint: If you want to reuse this sound/mp3 later in this movie,
create a reusable SWF::SoundStream object and then put it into
setSoundstream().
$soundinstance = $m->startSound($sound)
Play a prepared SWF::Sound object into the main timeline. Returns
an object of SWF::SoundInstance.
$sound = new SWF::Sound("loveyoutoo.mp3", SWF_SOUND_MP3_COMPRESSED );
$si = $m->startSound($sound);
$m->stopSound($sound)
Stop playing sound.
$m->labelFrame($string)
Gives the current frame a label that can be used by actionscript as
anchor. Then you don't have to count your nextFrame() lines
anymore. :-)
$m->labelFrame("win");
#ToDo:
#max characters of a label???
#What happen if we put there a big string??
#Which characters are allowed??
$m->setScriptLimits($maxRecursion, $timeout)
Set limits for resource usage, related to action script. Setting
timeout will protect your computer from too long loops and stack
overflow. So endless scripts like "while (1){};" will be
interrupted after timeout seconds. The default recursion depth is
265, the default timeout is 15 seconds.
$m->defineScene($offset, $name)
Define scenes for the movies' main timeline using integer value for
frame offset and name of the scene.
$m->setNetworkAccess($flag)
Sets network / fileaccess policy. If the flag is set to 0 a localy
loaded movie will be unable to access the network but is allowed to
access local files. If the flag ist set to 1 a localy loaded movie
will be unable to access local files but is allowed to access the
network. For SWF >= 8: default is 0,
$m->addMetadata($xml)
Adds Metadata to the movie: this function inserts a metadata-tag
into the movie. Only one metadata-tag can be set to a movie.
Metadata is specified as an XML string.
$m->assignSymbol($character, $name)
Assigns a symbolic name for a SWF::Character object. Such classes
are available for usage in other SWF files and can be referenced
from inside the current movie. To assign a symbol to the root
movie use NULL as character value.
$m->setTabIndex($depth, $index)
Sets tab index for specified depth level.
$fontchar = $m->addFont($font)
Adds a font to a movie. An object of SWF::FontCharacter class
returned.
$font = new SWF::Font('Arial.fdb');
$fch = $m->addFont($font);
$fontchar = $m->importFont($file, $name)
Imports a font from an other SWFFile. An object of
SWF::FontCharacter class returned.
$fch = $m->importFont('textField.swf', 'Arial337a');
$m->importCharacter($url, $name)
Not yet documented (ToDo!)
$result = $m->replace($item, $block)
This method replaces a displayable character with a new one.
Returns 0 on success , -1 else.
$dispitem = $movie->add($shape1);
$movie->nextFrame();
print $movie->replace($dispitem, $shape2);
$movie->nextFrame();
$written = $m->xs_output([$compresslevel])
$written = $m->output([$compresslevel])
Writes the SWF::Movie to stdout. This is normally used for
webservers/cgi-scripts. Don't forget to send the
"Content-Type:"-lines before writing out the movie.
The parameter compresslevel is optional. compresslevel between 0
and 9. Higher values will be interpreted as 9. Values smaller 0
mean no compression. By default the SWF::Movie will be send without
compression. Notice: compression available since Flash MX(Flash
6). Ming does not check this for you if you write flash4 or flash5
movies.
Unlike xs_output() the output() method prepared for using via
webservers (but not limited to webservers).
Both methods return number of bytes written.
$written = $m->save($filename [, $compresslevel])
Method saves the SWF::Movie to a file and returns the number of
bytes written. The parameter compresslevel is optional.
compresslevel between 0 and 9. Higher values will be interpreted as
9. Values smaller 0 mean no compression. By default the SWF::Movie
will be saved without compression. Notice: compression available
since Flash MX(Flash 6). Ming does not check this for you if you
write flash4 or flash5 movies.
