如何使用ng2- pdf -viewer获取pdf格式的点击部分坐标

npm install ng2-pdf-viewer

import { Component } from '@angular/core';
import { PDFDocumentProxy, PDFPageProxy } from 'ng2-pdf-viewer';

export class YourComponent {
  clickCoordinates: { x: number, y: number }[] = [];
}

<pdf-viewer
  [src]="pdfUrl"
  (after-load-complete)="onPDFLoadComplete($event)"
  (click)="onPDFClick($event)"
></pdf-viewer>

export class YourComponent {
  pdfUrl = 'path/to/your/pdf/file.pdf';

  onPDFLoadComplete(pdf: PDFDocumentProxy) {
    // PDF加载完成后的处理逻辑
  }

  onPDFClick(event: MouseEvent) {
    const pdfViewerElement = event.target as HTMLElement;
    const boundingRect = pdfViewerElement.getBoundingClientRect();
    const offsetX = event.clientX - boundingRect.left;
    const offsetY = event.clientY - boundingRect.top;
    const clickCoordinate = { x: offsetX, y: offsetY };
    this.clickCoordinates.push(clickCoordinate);
  }
}
