Button("添加示例文字")
          .fontSize(12)
          .onClick(async () => {
            let page: pdfService.PdfPage = this.document.getPage(this.pageIndex);
            let textStyle: pdfService.TextStyle = new pdfService.TextStyle;
            let fontList: Array<string> = font.getSystemFontList();
            if (fontList.length == 0) {
              this.showDialog('系统无可用字体','请尝试更新版本或设备');
              return;
            }
            let fontInfo: font.FontInfo = font.getFontByName(fontList[0]); //获取系统默认字体
            textStyle.fontInfo = { fontPath: fontInfo.path };
            textStyle.textSize = 20;
            page.addTextObject("hello world", 0, 0, textStyle); //添加示例文字
            this._pixelMap = page.getPagePixelMap();
          }).margin({ left: 15 })
