Used this module in ionic page

Add the module in an ionic page with this line.

<color-picker [connectingLineColor]="'yellow'" (colorChanged)="newcolor($event)" ></color-picker>

The module comes with differents and optionals parameters described as follow :

/* ================ INPUTS =================*/
[connectingLineColor]="'yellow'" /* Connecting line betwen center circle and gauge user click (default : yellow) */

[connectingLineThickness]="5" /*  Connecting line thickness (default : 5) */

[enable]="true" /* Enable or disable color picker (default is true, enabled) */

[outputColorFormat]="'HEX'" /* Select output format value (default is 'HEX')(possibilities : 'RGBW' - 'RGB' - 'HEX') */

[imageB64Source]="base64Imagesource"
/* This component allow you to change to background image of circular color picker. 
 Image should be 300x300px and type of : "data:image/png;base64 ... " 
 Transparent pixels will be ignored on user selection */
 
[selectedColor]="#ff0100" /* Pre-selected color (no default pre-selected color) */
 
 /* ================= OUTPUTS ================= */
(colorChanged)="newcolor($event)"  /* Subscribe to event when user as selected a new color */

(isUsed)="func($event)" /* Subscribe to event allowing you to know if user is using the color picker ($event is boolean value) */

You should take care of colorChanged event. It will be called each time a new color is found (if user slide on color picker, called a lot of times).

You can use the isUsed event output in order to block page scrolling/change in your application.

newcolor(color){
 selectedColor = color;
}
