# NAME

SWF::Bitmap - Bitmap class

# SYNOPSIS

            use SWF::Bitmap;
            $bitmap = new SWF::Bitmap('filename');
            $fill = $shape->addBitmapFill($bitmap);

# DESCRIPTION

SWF::Bitmap enables you to add JPG and DBL files. It is a helper class most useful for filling shapes (i.e. SWF::Shape objects). DBL files ('Define Bitmap Lossless') are produced from PNG or GIF files by using png2dbl or gif2dbl tools.

# METHODS

new SWF::Bitmap($file, [$alpha])

  Creates a new SWF::Bitmap object using 'file'. The file extension has to be one of ".jpg",".jpeg" or ".dbl" (not case sensitive). In all other cases use either `newSWFDBLBitmap()` or newSWFJpeg...() constructors. The alpha parameter represents a filename for opacity data ('alpha' channel), but only for JPG files. Alpha data files are produced by tool gif2mask. The original GIF used for gif2mask input file containing alpha information should have same dimensions (width x height) as the JPG file.

newSWFDBLBitmap SWF::Bitmap($file)

  Creates a new SWF::Bitmap object using DBL file. Use this constructor if you have a file with DBL data, but not with .dbl filename extension.

newSWFJpegBitmap SWF::Bitmap($file)

  Creates a new SWF::Bitmap object using JPG file. Use this constructor if you have a file with JPG data, but not with .jpg or .jpeg filename extension.

newSWFJpegWithAlpha SWF::Bitmap($file,$alpha)

  Creates a new SWF::Bitmap object using JPG file similar `newSWFJpegBitmap()` with additional opacity information in 'alpha' file. Use this constructor if you have a file with JPG data, but not with .jpg or .jpeg filename extension and if there is opacity information available in 'alpha' file. Alpha data files are produced by gif2mask tool. The original GIF file containing alpha information used for gif2mask input should have same dimensions as the JPG file.

$width = $bitmap->`getWidth()`;

  Returns width of bitmap in pixels.

$height = $bitmap->`getHeight()`;

  Returns height of bitmap in pixels.
