Class members

Properties

Name	Type	Default value	Description
color	ThemePalette		Theme color palette for the component.
value	string		Icon value, which can be either a ligature name or a custom icon in the format [namespace]:[name].

Details

You can register custom SVG files as named icons in the format [namespace]:[name].

The example below shows how to register a new icon named adf:move_file that points to an external file within the assets folder:

import { Component, OnInit } from '@angular/core';
import { MatIconRegistry } from '@angular/material/icon';
import { DomSanitizer } from '@angular/platform-browser';

@Component({...})
export class AppComponent implements OnInit {

    constructor(
        private matIconRegistry: MatIconRegistry,
        private sanitizer: DomSanitizer
    ) {}

    ngOnInit() {
        this.matIconRegistry.addSvgIconInNamespace(
            'adf',
            'move_file',
            this.sanitizer.bypassSecurityTrustResourceUrl(
                './assets/images/adf-move-file-24px.svg'
            )
        );
    }
}

In the HTML, you can now use the icon as shown below:

<adf-icon value="adf:move_file"></adf-icon>

Thumbnail Service

You can also reference the icons registered with the Thumbnail Service using the adf: namespace.

<adf-icon value="adf:image/gif"></adf-icon>
