Package org.pepstock.charba.client.colors

Contains the enumerations of HTML and GWT Material colors, to consume out-of-the-box, and utilities to create and manage own colors and classes to define gradients of patterns for charts.

Interface Summary

Interface	Description
IsColor	Defines the methods that all colors must have and many of them have got already an implementation that usually does not need to be changed.

Class Summary

Class	Description
Area	Contains the coordinates of an area. Used inside the canvas object factory.
CanvasObject	Base object for pattern and gradient instances, based on canvas element.
CanvasObjectFactory	Abstract utility class which creates a canvas gradient and pattern java script objects using a Charba gradient or pattern. A Charba gradient or pattern describes how a canvas gradient or pattern must be created.
Center	Contains the coordinates of a center of arc. Used inside the canvas object factory.
Color	This class contains information about a color. You can requests a specific alpha (starting form source color and cloning it).
ColorBuilder	Utility to create colors by red, green and blue values, HEX value and RGB and RGBA strings. It checks if the requested color is already defined in HTML colors.
ColorUtil	Utility to check alpha value. Internally is checking red, green, blue and alpha values and creates string representation of a color, to HEX, RGB, RGBA, HSL or HSLA strings.
Gradient	A gradient is an image consisting of a progressive transition between two or more colors. Could be Linear or Radial. Can be created using the size of CANVAS or CHART area. The orientation to have a progressive transition, is defined by an enumeration in order to creates the gradient using the right coordinates and dimension, based on existing items (canvas and chart).
GradientBuilder	The gradient builder is the entry point to create a canvas gradient. A gradient is an image consisting of a progressive transition between two or more colors. Could be Linear or Radial. Can be created using the size of CANVAS or CHART area. The orientation to have a progressive transition, is defined by an enumeration in order to creates the gradient using the right coordinates and dimension, based on existing items (canvas and chart).
GradientColor	Contains the color and its offset to set a gradient.
Pattern	Entity to apply a canvas pattern in the a data set as background. See here some interesting pattern images.
PatternBuilder	The pattern builder is the entry point to create a canvas pattern. Entity to apply a canvas pattern in the a data set as background. See here some interesting pattern images.
Radius	Contains the radius of inner and outer of an arc. Used inside the canvas object factory.

Enum Summary

Enum	Description
GoogleChartColor	Google Chart colors provided as enumeration of colors.
GradientOrientation	Represents the gradient orientation for gradient. Every orientation contains also on which gradient type can be applied.
GradientScope	A gradient needs to have coordinates and/or radius to be created. The dimension to create a gradient are decided by Charba, automatically based on canvas or chart area element.
GradientType	A gradient must have a type. The possible types are: LINEAR RADIAL
GwtMaterialColor	GWT material color constants.
HtmlColor	All modern browsers support the following 140 color names.
UiGradient	uiGradients is a community contributed collection of beautiful multi-color gradients. Enumerates the uiGradients items, with a set of predefined colors, in order to create Charba Gradients.
