创建横线遇到的问题：

格局太小，之前没有想过PdfCanvas要变成照片形式利用起来，于是创建了多个PdfCanvas，导致无法将多个PdfCanvas变成一个PdfCanvas利用，代码如下：

// TODO: 实现印章
		PdfPage pdfPage = pdfdocument.getPage(1);
		PdfCanvas pdfCanvas1 = new PdfCanvas(pdfPage);

		// 直线问题
		// 第一个
		pdfCanvas1.moveTo(299, 475);
		PdfCanvas line = pdfCanvas1.lineTo(342, 475);
		line.setLineWidth(500f);
		line.setColor(ColorConstants.RED, true);

		pdfCanvas1.fill();

		// 第二个
		PdfCanvas pdfCanvas2 = new PdfCanvas(pdfPage);
		pdfCanvas2.moveTo(297, 462);
		PdfCanvas line2 = pdfCanvas2.lineTo(344, 462);
		line2.setLineWidth(500f);
		line2.setColor(ColorConstants.RED, true);

		pdfCanvas2.fill();

		// 第三个
		PdfCanvas pdfCanvas3 = new PdfCanvas(pdfPage);
		pdfCanvas3.moveTo(301, 450);
		PdfCanvas line3 = pdfCanvas3.lineTo(340, 450);
		line3.setLineWidth(500f);
		line3.setColor(ColorConstants.RED, true);

		pdfCanvas3.fill();

这样就变成了了：多条直线是于多个PdfCanvas组成的，没法将其变成照片，难道三个一起变吗?

不好实现，不过暂时看还是蛮好看的

于是进行代码优化：

// TODO: 实现印章
		PdfPage pdfPage = pdfdocument.getPage(1);
		PdfCanvas pdfCanvas1 = new PdfCanvas(pdfPage);

		// 直线问题
		// 第一个
		pdfCanvas1.moveTo(299, 475);
		pdfCanvas1.lineTo(342, 475).setColor(ColorConstants.RED, true);
		pdfCanvas1.fill();

		// 第二个
		pdfCanvas1.moveTo(297, 462);
		pdfCanvas1.lineTo(344, 462).setColor(ColorConstants.RED, true);
		pdfCanvas1.fill();

		// 第三个
		pdfCanvas1.moveTo(301, 450);
		pdfCanvas1.lineTo(340, 450).setColor(ColorConstants.RED, true);
		pdfCanvas1.fill();

叫自己一声小天才，这也可以

保存代码，明天干

尾声：

最后前端几行代码实现了，搞不搞这么复杂的PDF，为什么需要后端一点一点画出来，太扎心了

很疑惑，Java实现PDF的意义在哪里，技术难道不应该是谁方便谁做吗，后端做前端实现不了的，前端做后端实现不了的

一个星期的任务就这么……
