man SWF::Shape (3): Shape class

SYNOPSIS

use SWF::Shape;
$shape = new SWF::Shape();
$dispitem = $movie->add($shape);

DESCRIPTION

SWF::Shape is the fundamental object of a flash movie.

METHODS

new SWF::Shape()

Creates a new Shape object.

$shape->movePenTo($x, $y)

Move the Shape's (imaginary) pen location to ($x, $y) in the Shape's coordinate space.

$shape->movePen($dx, $dy)

Add ($dx, $dy) to the Shape's pen current location.

$x = $shape->getPenX()

Returns Pen's x-coordinates

$y = $shape->getPenY()

Returns Pen's y-coordinates

($x, $y) = $shape->getPen()

Returns Pen's (x,y) coordinates

$shape->drawLineTo($x, $y)

Draw a line (using current line style, set by one of the setLine...() methods) from the current position to ($x, $y).

$shape->drawLine($dx, $dy)

Draw a line (using current line style set by one of the setLine...() methods) from the current position to displacement ($dx, $dy).

$shape->drawCurveTo($controlx, $controly, $anchorx, $anchory)

Draw a quadratic curve (using current line style, set by one of the setLine...() methods) from current pen position to ($anchorx, $anchory) using control point ($controlx, $controly).

$shape->drawCurve($controldx, $controly, $anchorx, $anchory)

Draw a quadratic curve (using current line style, set by one of the setLine...() methods) from current pen position to displacement ($anchordx, $anchordy) using displacement control point ($controldx, $controldy).

$shape->drawCubicTo($bx,$by,$cx,$cx,$dx,$dy)

$shape->drawCubic($bx,$by,$cx,$cx,$dx,$dy)

Draw a cubic curve (using current line style). [ToDo: Add some more details and demo code]

$shape->setLine($width, $r, $g, $b [,$a])

Sets Shape's line width and color (RGB). To remove the Shape's line style call $shape->hideLine(). The used line width for drawing is a product of $width argument and scale value set, see SWF::setScale($scale). Arguments $r, $g, $b stand for red, green and blue color parts, optional $a for alpha value.

$shape->setLineStyle($width, $r, $g, $b [,$a])

This OLD deprecated method is documented here only for compatibility reason. The line width -in TWIPS units- is independent of Ming scale value (more bug than feature).

$shape->setLine2($width, $r, $g, $b ,$a, $flags, $miterLimit)

A new method available for SWF version >=8 setting shape's line width and color (RGBA) with additional control flags (see below) and miter limit. To remove the Shape's line style call $shape->hideLine(). The used line width for drawing is a product of $width argument and scale value set, see SWF::setScale($scale). Arguments $r, $g, $b, $a stand for red, green, blue and alpha color parts. $a is not optional here.

Available flags are: Line cap style: select one of the following flags (default is round cap style)

        SWF_LINESTYLE_CAP_ROUND 
        SWF_LINESTYLE_CAP_NONE
        SWF_LINESTYLE_CAP_SQUARE

Line join style: select one of the following flags (default is round join style)

        SWF_LINESTYLE_JOIN_ROUND
        SWF_LINESTYLE_JOIN_BEVEL 
        SWF_LINESTYLE_JOIN_MITER

Scaling flags: disable horizontal / vertical scaling

        SWF_LINESTYLE_FLAG_NOHSCALE
        SWF_LINESTYLE_FLAG_NOVSCALE

Enable pixel hinting to correct blurry vertical / horizontal lines: all anchors will be aligned to full pixels

        SWF_LINESTYLE_FLAG_HINTING

Disable stroke closure: if no-close flag is set caps will be applied instead of joins.

        SWF_LINESTYLE_FLAG_NOCLOSE

End-cap style: default round

        SWF_LINESTYLE_FLAG_ENDCAP_ROUND
        SWF_LINESTYLE_FLAG_ENDCAP_NONE
        SWF_LINESTYLE_FLAG_ENDCAP_SQUARE

If join style is SWF_LINESTYLE_JOIN_MITER a miter limit factor must be set. Miter max length is then calculated as: max miter len = miter limit * width. If join style is not miter, this value will be ignored.

$shape->setLineStyle2($width, $r, $g, $b ,$a, $flags, $miterLimit)

This OLD deprecated method is mentioned here only for compatibility reason, you'd better use setLine2().

$shape->setLine2Filled($width, $fill, $flags, $miterLimit)

A new method available for SWF version >=8 setting shape's line width and fill style, $fill is an object of SWF::Fill class. For other argument details see item $shape->setLine2().

$shape->setLine2StyleFilled($width, $fill, $flags, $miterLimit)

This OLD deprecated method is mentioned here only for compatibility reason, you'd better use setLine2Filled().

$shape->hideLine()

Remove the Shape's line, i.e. make lines painted after this method call invisible.

$fill = $shape->addSolidFill($r, $g, $b [,$a])

$fill = $shape->addFill($r, $g, $b [,$a])

Adds a solid fill to $shape list of fill styles and returns an SWF::Fill object. This object is used with the ``setLine()'' method described below. The default value of $a is 0.

$fill = $shape->addBitmapFill($bitmap [,FLAG])

$fill = $shape->addFill($bitmap [,FLAG])

Adds a bitmap fill to $shape list of fill styles and returns an SWF::Fill object. This object is used with the ``setLine()'' method described below.

$bitmap is an SWF::Bitmap object while FLAG argument can be SWFFILL_TILED_BITMAP or SWFFILL_CLIPPED_BITMAP. Make sure to import these constants to your package before useing it, i.e. use the following statement:

     use SWF::Fill <list of constants>;

The default value of FLAG is SWFFILL_TILED_BITMAP.

$fill = $shape->addGradientFill($gradient [,FLAG])

$fill = $shape->addFill($gradient [,FLAG])

Adds a gradient fill to $shape list of fill styles and returns an SWF::Fill object. This object is used with the ``setLine()'' method described below.

$gradient is an SWF::Gradient object while FLAG argument can be SWFFILL_LINEAR_GRADIENT or SWFFILL_RADIAL_GRADIENT, plus SWFFILL_FOCAL_GRADIENT for V8. Make sure to import these constants to your package before useing it, i.e. use the following statement:

     use SWF::Fill <list of constants>;

The default value of FLAG is SWFFILL_LINEAR_GRADIENT.

$shape->xs_setLeftFill($fill)

$shape->setLeftFill($fill)

Sets the fill on the left side of the edge. $fill is an SWF::Fill object returned from ``addFill'' method.

$shape->setLeftFill($r, $g, $b [,$a])

This is another way of saying:

     my $fill = $shape->addSolidFill($r, $g, $b [,$a]);
     $shape->setLeftFill($fill);

$shape->xs_setRightFill($fill)

$shape->setRightFill($fill)

Sets the fill on the right side of the edge. $fill is an SWF::Fill object returned from ``addFill'' method.

$shape->setRightFill($r, $g, $b [,$a])

This is another way of saying:

     my $fill = $shape->addSolidFill($r, $g, $b [,$a]);
     $shape->setRightFill($fill);

$shape->drawCircle($r)

Draws a circle with radious $r, also changes current position.

$shape->drawArc($r, $startAngle, $endAngle)

Draws an arc with radious $r form start to end.

$shape->useVersion(version)

This function allows to set the shapes version information. The version is only a hint. If necessary the version is upgraded. Valid values: are 3 and 4. Value of 3 is default, but 4 if linestyle2 is used. Some shape features are available only for shape version 4 and SWF file version>=8. One example is the usage of focal gradients:

        $g = new SWF::Gradient();
        $g->setFocalPoint(-0.9);
        $g->addEntry(0.000000,0xff,0x00,0x00,0xff);
        $g->addEntry(1.000000,0x00,0xff,0x00,0xff);
        $shape->useVersion(4);
        $shape->addGradientFill($g,SWFFILL_FOCAL_GRADIENT);

$version = $shape->getVersion()

Gets the current shape object version.

$shape->dumpOutline()

Returns a string describing shape's outline. After drawing in a shape expect getting a multi-line string like:

        moveto 368,5
        curveto 348,5 327,1
        curveto 307,-3 284,-15
etc. etc.

$shape->end()

Stops drawing on this shape and make the shape complete. Further method calls won't produce any lines, circles etc. By using this demo code later no circle is painted:

        $shape->drawLineTo(300,300);
        $shape->end();
        $shape->drawCircle(200);

$shape->drawGlyph($font, $cnumber [, $size])

Draws character of $cnumber of $font. Also Unicode fonts are possible, if the font does provide that, just like next example:

        $font=new SWF::Font("Thai-Bold.fdb");
        $sh->drawGlyph($font, 0x0E44, 44);

$shape->drawCharacterBounds($character)

Draws an outer rectangle fitting for $character, an object of SWF::Character.

$shape->setRenderHintingFlags(flags)

Set render hinting flags. Possible values are SWF::Constants::SWF_SHAPE_USESCALINGSTROKES and
SWF::Constants::SWF_SHAPE_USENONSCALINGSTROKES

This method also will set version of this SWF::Shape object to 4.
