Classe: Image_Color - X-Ref
Image_Color handles color conversion and mixing.| mixColors($col1 = false, $col2 = false) X-Ref |
| Mix two colors together by finding their average. If the colors are not passed as parameters, the class's colors will be mixed instead. author: Jason Lotito <jason@lehighweb.com> param: string $col1 The first color you want to mix param: string $col2 The second color you want to mix return: string The mixed color. |
| setWebSafe($bool = true) X-Ref |
| Determines whether colors the returned by this class will be rounded to the nearest web safe value. author: Jason Lotito <jason@lehighweb.com> param: boolean $bool Indicates if colors should be limited to the return: void |
| setColors($col1, $col2) X-Ref |
| Set the two colors this class uses for mixing and ranges. author: Jason Lotito <jason@lehighweb.com> param: string $col1 The first color in hex format param: string $col2 The second color in hex format return: void |
| getRange($degrees = 2) X-Ref |
| Get the range of colors between the class's two colors, given a degree. author: Jason Lotito <jason@lehighweb.com> param: integer $degrees How large a 'step' we should take between the return: array Returns an array of hex strings, one element for each |
| changeLightness($degree = 10) X-Ref |
| Change the lightness of the class's two colors. author: Jason Lotito <jason@lehighweb.com> param: integer $degree The degree of the change. Positive values return: void |
| getTextColor($color, $light = ') X-Ref |
| Determine if a light or dark text color would be more readable on a background of a given color. This is determined by the G(reen) value of RGB. You can change the dark and the light colors from their default black and white. author: Jason Lotito <jason@lehighweb.com> param: string $color The hex color to analyze param: string $light The light color value to return if we should param: string $dark The dark color value to return if we should have return: string The light or dark value which would make the text most |
| _setColors($col1, $col2) X-Ref |
| Internal method to set the colors. author: Jason Lotito <jason@lehighweb.com> param: string $col1 First color, either a name or hex value param: string $col2 Second color, either a name or hex value return: void |
| _splitColor($color) X-Ref |
| Given a color, properly split it up into a 3 element RGB array. author: Jason Lotito <jason@lehighweb.com> param: string $color The color. return: array A three element RGB array. |
| _returnColor( $color ) X-Ref |
| This is deprecated. Use rgb2hex() instead. |
| rgb2hex($color) X-Ref |
| Convert an RGB array to a hex string. author: Jason Lotito <jason@lehighweb.com> param: array $color 3 element RGB array. return: string Hex color string. |
| hex2rgb($hex) X-Ref |
| Convert a hex color string into an RGB array. An extra fourth element will be returned with the original hex value. author: Jason Lotito <jason@lehighweb.com> param: string $hex Hex color string. return: array RGB color array with an extra 'hex' element containing |
| hsv2rgb($h, $s, $v) X-Ref |
| Convert an HSV (Hue, Saturation, Brightness) value to RGB. author: Jason Lotito <jason@lehighweb.com> param: integer $h Hue param: integer $s Saturation param: integer $v Brightness return: array RGB array. |
| hsv2hex($h, $s, $v) X-Ref |
| Convert HSV (Hue, Saturation, Brightness) to a hex color string. Originally written by Jurgen Schwietering. Integrated into the class by Jason Lotito. author: Jurgen Schwietering <jurgen@schwietering.com> param: integer $h Hue param: integer $s Saturation param: integer $v Brightness return: string The hex string. |
| allocateColor(&$img, $color) X-Ref |
| Allocates a color in the given image. User defined color specifications get translated into an array of RGB values. param: resource $img Image handle param: string|array $color Name or hex string or an RGB array. return: resource Image color handle. |
| color2RGB($color) X-Ref |
| Convert a named or hex color string to an RGB array. If the color begins with the # character it will be treated as a hex value. Everything else will be treated as a named color. If the named color is not known, black will be returned. author: Laurent Laville <pear@laurent-laville.org> param: string $color return: array RGB color |
| namedColor2RGB($color) X-Ref |
