<button (click)="page = page - 1">Previous</button>
<button (click)="page = page + 1">Next</button>

Zoom

<pdf-viewer [src]="'path/to/pdf-file.pdf'" [zoom]="zoom"></pdf-viewer>
<button (click)="zoom = zoom + 0.1">Zoom In</button>
<button (click)="zoom = zoom - 0.1">Zoom Out</button>

Rotation

This feature allows you to rotate the PDF document. The 'rotation' attribute specifies the rotation angle, and you can use a button to rotate the document by 90 degrees.
