NAME

Image::XBin - (DEPRECATED) Load, create, manipulate and save XBin image files

DEPRECATION NOTICE

This module has been replaced by Image:TextMode.

SYNOPSIS

use Image::XBin;

            # Read in a file...
            my $img = Image::XBin->new( file => 'myxbin.xb' );

            # Image width and height
            my $w = $img->width;
            my $h = $img->height;

            # get and put "pixels"
            my $pixel = $img->getpixel( $x, $y );
            $img->putpixel( $x, $y, $pixel );

            # font (XBin::Font)
            my $font = $img->font;

            # palette (XBin::Palette)
            my $palette = $img->palette;

            # save the data to a file
            $img->write( file => 'x.xb' );

DESCRIPTION

XBin stands for "eXtended BIN" -- an extention to the normal raw-image BIN files.

XBin features:

• allows for binary images up to 65536 columns wide, and 65536 lines high
• can have an alternate set of palette colors either in blink or in non-blink mode
• can have different textmode fonts from 1 to 32 scanlines high, consisting of either 256 or 512 different characters
• can be compressed

XBin file stucture:

            +------------+
            | Header     |
            +------------+
            | Palette    |
            +------------+
            | Font       |
            +------------+
            | Image Data |
            +------------+

Note, the only required element is a header. See the XBin specs for for information. http://www.acid.org/info/xbin/xbin.htm

METHODS
new( %options )
Creates a new XBin image. Currently only reads in data.

            # filename
            $xbin = Image::XBin->new( file => 'file.xb' );
            
        # file handle
            $xbin = Image::XBin->new( handle => $handle );

            # string
            $xbin = Image::XBin->new( string => $string );

clear( )
Clears any in-memory data.

read( %options )
Explicitly reads in an XBin.

write( %options )
Write the XBin data to a file, handle of string.

as_string( )
Returns the XBin data as a string - suitable for saving.

as_png( [%options] )
Returns a binary PNG version of the image.

            # Thumbnail -- Default
            $xbin->as_png( mode => 'thumbnail' );

            # Full size
            $xbin->as_png( mode => 'full' );

This function is just a wrapper around as_png_thumbnail() and as_png_full().

as_png_thumbnail( [%options] )
Creates a thumbnail version of the XBin.

as_png_full( [%options] )
Creates a full-size replica of the image. You can pass a "crop" option to crop the image at certain height.

            # Crop it after 25 (text-mode) rows
            $xbin->as_png_full( crop => 25 );

has_palette( )
Returns true if the file has a palette defined.

has_font( )
Returns true if the file has a font defined.

is_compressed( )
Returns true if the data was (or is to be) compressed

is_nonblink( )
Returns true if the file is in non-blink mode.

has_512chars( )
Returns true if the font associated with the XBin has 512 characters

sauce( [File::SAUCE] )
Gets / sets the SAUCE object associated with the XBin.

putpixel( $x, $y, $pixel )
Sets the pixel at $x, $y with $pixel (which should be an Image::XBin::Pixel).

getpixel( $x, $y )
Returns the Image::XBin::Pixel object at $x, $y (or undef).

pixel( [$x, $y, $pixel] )
Generic get / set method used by both getpixel and putpixel.

font( [Image::XBin::Font] )
Gets or sets the font. Must be of type Image::XBin::Font. Passing anything but that type will remove the font and change related header data.

palette( [Image::XBin::Palette] )
Gets or sets the palette. Must be of type Image::XBin::Palette. Passing anything but that type will remove the font and related header data.

compress( [true or false] )
Get / sets the compression header value to true or false. Affect the output from as_string() and write().

width( )
Returns the image width.

height( )
Returns the image height.

TODO

• fix write() method to include compression
• use new()'s options to create a new file from scratch
