SWF::Builder::CharacteUseriContributed Perl SWF::Builder::Character::Bitmap(3)

NAME
       SWF::Builder::Character::Bitmap - SWF Bitmap object

SYNOPSIS
	   my $jpeg = $mc->new_jpeg( 'picture.jpg' );
	   $jpeg->place;

	   use GD;
	   $gd = GD::Image->newFromPng(	'tile.png' );
	   my $bm = $mc->new_bitmap( $gd, 'GD' );
	   my $shape = $mc->new_shape
		       ->fillstyle($bm,	'tiled', $bm->matrix)
		       ->box(0,	0, 100,	100);

DESCRIPTION
       SWF supports JPEG and lossless bitmaps.

       $jpg_bm = $mc->new_jpeg(	JPEGFile => $filename /	JPEGData => $jpegdata,
       AlphaFile => $filename /	AlphaData => $alphadata	/ Alpha	=> $alpha )
       $jpg_bm = $mc->new_jpeg(	$filename )
	   returns a new JPEG bitmap. It can take named	parameters as follows:

	   JPEGFile / JPEGData
	       set a JPEG Data from a file and a binary	data string,
	       respectively.

	   AlphaFile / AlphaData / Alpha
	       set an alpha (transparency) data	from a file, a binary data
	       string, and a single byte, respectively.	 The alpha data	is
	       width x height length string of byte, 0(transparent) to
	       255(opaque). A single byte Alpha	is expanded into the proper
	       size.

	   When	you give a single parameter, it	is regarded as the JPEG	file
	   name. Same as JPEGFile => $filename.

       $jpg_bm->JPEGData/AlphaData/Alpha( $data	)
	   set a JPEG/Alpha data.

       $jpg_bm->load_jpeg/load_alpha( $filename	)
	   load	a JPEG/alpha data file.

       $ll_bm =	$mc->new_bitmap( $obj [, $type]	)
	   returns a new lossless bitmap converted from	a $type	of $obj.  If
	   $type is omitted, it	is guessed.  If	$obj is	not an object, it is
	   treated as a	file name.

	   Acceptable types are	as follows:

	   GD  takes a GD::Image object.

	   ImageMagick
	       takes an	Image::Magick object.

	   Custom
	       takes an	array reference	of [ $width, $height, $colors,
	       $is_alpha, \&pixsub ].  $width and $height are the width	and
	       height of the bitmap.  $colors is a total number	of colors of
	       the bitmap. If it is under 256, the bitmap is converted to
	       colormapped image, otherwise 24-bit full	color.	$is_alpha is a
	       flag whether the	bitmap has an alpha data.  &pixsub is a
	       subroutine, which takes pixel coordinates ($x, $y) and returns
	       an array	of the color data of the pixel,	($r, $g, $b, $a).

       $bm->width
	   returns the bitmap width.

       $bm->hegiht
	   returns the bitmap height.

       $bm->get_bbox
	   returns the bounding	box of the bitmap, (0, 0, width, height).

       $bm->matrix
	   returns a bitmap transformation matrix.

       $bm_i = $bm->place( ... )
	   returns the display instance	of the bitmap (to be exact, returns
	   the instance	of a box shape which filled with the bitmap).  See
	   SWF::Builder.
