SYNOPSIS ^

 use App::MathImage::Image::Base::BMP;
 my $image = App::MathImage::Image::Base::BMP->new (-width => 100,
                                                    -height => 100);
 $image->rectangle (0,0, 99,99, '#FFF'); # white
 $image->xy (20,20, '#000');             # black
 $image->line (50,50, 70,70, '#FF00FF');
 $image->line (50,50, 70,70, '#0000AAAA9999');

Colour Names

There's no named colours as such, only hex

    #RGB

FUNCTIONS ^

$image = App::MathImage::Image::Base::BMP->new (key=>value,...)

Create and return a new image object. A new image can be started with -width and -height,

    $image = App::MathImage::Image::Base::BMP->new (-width => 200, -height => 100);

Or an existing file can be read,

    $image = App::MathImage::Image::Base::BMP->new (-file => '/some/filename.bmp');

Or an Image::BMP object can be given,

    my $bmpobj = Image::BMP->new (20, 10);
    $image = App::MathImage::Image::Base::BMP->new (-imagebmp => $bmpobj);
$new_image = $image->new (key=>value,...)

There's no image clone as yet.

$image->load ()
$image->load ($filename)

Read the -file, or set -file to $filename and then read.

$image->save ()
$image->save ($filename)

Save to -file, or with a $filename argument set -file then save to that.

ATTRIBUTES ^

-width (integer)
-height (integer)

The size of the image.

-imagebmp

The underlying Image::BMP object.
