NAME

       odfhighlight - search, replace and highlight text in a document

SYNOPSIS

       odfhighlight "source.odt" "search string" -r "replacement" -o "target.odt"

       replaces "search string" by "replacement" in the file "source.odt", highlights each replacement with a yellow (default) backgound, then
       writes the resulting document as "target.odt"

       odfhighlight "myfile.odt" "search string" -color "green"

       highlights each occurrence of "search string" in "myfile.odt" with a green background color, without changing the text (without "-o"
       option, the changes apply to "myfile.odt"

ARGUMENTS AND OPTIONS

   Default behaviour
       With the "minimal" command line, with only a filename and a string as arguments, each matching string is highlighted with a yellow
       background and represented with the "Standard" style.

   Options
	       -e --encoding "xxxxxx"

		       character set to use, if different from the default

	       -r --replacement "new string"

		       "new string" is used as a replacement for "search string"

	       -c --color "code"

		       an RGB color code, expressed either as the concatenation of
		       3 comma-separated decimal values (each one in the range
		       0..255, ex: "72,61,139" for a dark slate blue), or a 6-digit
		       hexadecimal number, preceded by a "#" (ex: #00ff00 for green)
		       or, if a colormap is available and known in your
		       OpenOffice::OODoc installation, a symbolic color name (ex:
		       "sky blue")

	       -s --stylename "name"

		       the name of the color style (default: "MyHighlight"); the
		       user must provide a style name that is not already in use
		       in the document

	       -p --property "property=value"

		       This option can be repeated; each occurrence gives an
		       additional property for the highlight style (font name, size,
		       foreground color, ...). For example, with the combination of
		       -p 'fo:color=#ff0000' and -p 'fo:font-size=18pt', the
		       highlighted text will be made of 18pt-sized, red characters.
		       In order to master these options, you should have some
		       knowledge of the Form Objects (FO) vocabulary that is used
		       in the OpenDocument specification.

	       -o --output "filename"
	       -t --target "filename"

		       an alternative filename to save the modified document, when
		       the source document must remain unchanged

NAME

       "Convert::Color::RGB" - a color value represented as red/green/blue

SYNOPSIS

       Directly:

	use Convert::Color::RGB;

	my $red = Convert::Color::RGB->new( 1, 0, 0 );

	# Can also parse strings
	my $pink = Convert::Color::RGB->new( '1,0.7,0.7' );

       Via Convert::Color:

	use Convert::Color;

	my $cyan = Convert::Color->new( 'rgb:0,1,1' );

DESCRIPTION

       Objects in this class represent a color in RGB space, as a set of three floating-point values in the range 0 to 1.

       For representations using 8- or 16-bit integers, see Convert::Color::RGB8 and Convert::Color::RGB16.

CONSTRUCTOR

   $color = Convert::Color::RGB->new( $red, $green, $blue )
       Returns a new object to represent the set of values given. These values should be floating-point numbers between 0 and 1. Values outside of
       this range will be clamped.

   $color = Convert::Color::RGB->new( $string )
       Parses $string for values, and construct a new object similar to the above three-argument form. The string should be in the form

	red,green,blue

       containing the three floating-point values in decimal notation.

METHODS

   $r = $color->red
   $g = $color->green
   $b = $color->blue
       Accessors for the three components of the color.

   ( $red, $green, $blue ) = $color->rgb
       Returns the individual red, green and blue color components of the color value.

   $mix = $color->alpha_blend( $other, [ $alpha ] )
       Return a new color which is a blended combination of the two passed into it.  The optional $alpha parameter defines the mix ratio between
       the two colors, defaulting to 0.5 if not defined. Values closer to 0 will blend more of $color, closer to 1 will blend more of $other.

   $measure = $color->dst_rgb( $other )
       Return a measure of the distance between the two colors. This is the unweighted Euclidean distance of the three color components. Two
       identical colors will have a measure of 0, pure black and pure white have a distance of 1, and all others will lie somewhere inbetween.

   $measure = $color->dst_rgb_cheap( $other )
       Return a measure of the distance between the two colors. This is the sum of the squares of the differences of each of the color components.
       This is part of the value used to calculate "dst_rgb", but since it involves no square root it will be cheaper to calculate, for use in
       cases where only the relative values matter, such as when picking the "best match" out of a set of colors.  It ranges between 0 for
       identical colours and 3 for the distance between pure black and pure white.

EXAMPLES

   Generating Gradients
       The "alpha_blend" method can be used to generate a smooth gradient between two colours.

	use Convert::Color;

	my $blue = Convert::Color->new("vga:blue");
	my $cyan = Convert::Color->new("vga:cyan");

	say $blue->alpha_blend( $cyan, $_/10 )->as_rgb8->hex for 0 .. 10
