What are ngx-color-picker's main functionalities?

Basic Color Picker

This feature allows you to add a basic color picker to your Angular application. The selected color is bound to the 'color' variable in your component.

<color-picker [(color)]="color"></color-picker>

Preset Colors

This feature allows you to provide a set of preset colors that users can choose from. The 'presetColors' variable should be an array of color strings.

<color-picker [(color)]="color" [presetColors]="presetColors"></color-picker>

Output Events

This feature allows you to handle color change events. The 'onColorChange' method will be called whenever the user selects a new color.

<color-picker [(color)]="color" (colorChange)="onColorChange($event)"></color-picker>

Custom Styles

This feature allows you to customize the dimensions of the color picker. The 'cpWidth' and 'cpHeight' properties set the width and height of the color picker, respectively.

<color-picker [(color)]="color" [cpWidth]="200" [cpHeight]="200"></color-picker>
