Color::Object is a OO-Color Module. A module for manipulation Colors within RGB, HSV and HSL color-spaces for usage within PDF-Documents especially with the Text::PDF::API modules. SYNOPSIS use Color::Object, $cl = Color::Object->new, $cl = Color::Object->newRGB($r;$g,$b), $cl = Color::Object->newHSV($h,$s,$v), $cl = Color::Object->newHSL($h,$s,$l), $cl->setRGB($r;$g,$b), $cl->addBrightness($br), ($h,$s,$l) = $cl->asHSL, METHODS Color::Object->new Color::Object->newRGB $r; $g, $b Color::Object->newHSV $h, $s, $v Color::Object->newHSL $h, $s, $l Color::Object->newGrey $grey ( $r; $g, $b ) = $cl->asRGB Returns $cls rgb values. Range [0 . 1]. ( $h, $s, $v ) = $cl->asHSV Returns $cls hsv values. Ranges h [0 . 360], s/v [0 . 1]. ( $h, $s, $l ) = $cl->asHSL Returns $cls hsl values. Ranges h [0 . 360], s/l [0 . 1]. $grey = $cl->asGrey $grey = $cl->asGrey2 Returns $cls grey value. Range [0 . 1]. Functions 2 returns the geometric mean of the corresponding RGB values. ( $c, $m, $y )= $cl->asCMY Returns $cls cmy values. Range [0 . 1]. ( $c, $m, $y, $k )= $cl->asCMYK ( $c, $m, $y, $k )= $cl->asCMYK2 ( $c, $m, $y, $k )= $cl->asCMYK3 Returns $cls cmyk values. Range [0 . 1]. Function 2 returns a 25% lighter color-equivalent. Function 3 returns a 25% lighter color-equivalent. $hex = $cl->asHex Returns $cls rgb values as 6 hex-digits. $cl->setRGB $r; $g, $b Sets the $cls rgb values. Valid range [0 . 1]. $cl->setHSV $h, $s, $v Sets the $cls hsv values. Valid ranges: h [0.360], s/v [0.1]. $cl->setHSL $h, $s, $l Sets the $cls hsl values. Valid ranges: h [0.360], s/l [0.1]. $cl->setGrey $grey Sets the $cls grey value. Valid range [0 . 1]. $cl->setHex $hex Sets the $cls rgb values using 6 hex-nibbles. $cl->addSaturation $saturation Adds to the $cls saturation in the HSV model. Valid range [-1 . 1]. $cl->setSaturation $saturation Sets the $cls saturation in the HSV model. Valid range [0 . 1]. $cl->rotHue $degrees Rotates the $cls hue in the HSV/L model. Valid range [-360 . 360]. $cl->setHue $hue Sets the $cls hue in the HSV/L model. Valid range [0 . 360]. $cl->addBrightness $brightness Adds to the $cls brightness in the HSV model. Valid range [-1 . 1]. $cl->setBrightness $brightness Sets the $cls brightness in the HSV model. Valid range [0 . 1]. $cl->addLightness $lightness Adds to the $cls lightness in the HSL model. Valid range [-1 . 1]. $cl->setLightness $lightness Sets the $cls lightness in the HSL model. Valid range [0 . 1].
