这里要注意的是,此图像是A4 尺寸的纵向纸张图像。您可能需要将Bitmap picEdit = new Bitmap(PrePrintedCertificate, new System.Drawing.Size(1241, 1756)); 更改为Bitmap picEdit = new Bitmap(PrePrintedCertificate, new System.Drawing.Size(1756,1241));
另一件事是名称和其他详细信息已随机打印在图像上,但您可以看到您希望打印详细信息的确切位置。
您可以使用g.DrawRectangle(new System.Drawing.Pen(System.Drawing.Color.Red, 2), 662, 530, 90, 40);查看它的打印位置,您将在此处传递的参数将与 RectangleF 参数相同。
