using iTextSharp.text;

using iTextSharp.text.pdf;

 

string appPath = AppDomain.CurrentDomain.BaseDirectory;

Document doc = new Document(new Rectangle(390, 400), 0, 0, 0, 0); //纸张宽390 高400

PdfWriter.GetInstance(doc, new FileStream(appPath + "/DPD_15505984238198.pdf", FileMode.Create));

doc.Open();

//给pdf添加图片

string filesPath = appPath + (appPath.EndsWith("\\") ? "" : "\\") + "GzImage\\";

string gzImage = ReportPage.GetSession("gzImage");

 

Image image = Image.GetInstance(filesPath + gzImage);

float percentage = 1;

//这里都是图片最原始的宽度与高度

float resizedWidht = image.Width;

float resizedHeight = image.Height;

//这里用计算出来的百分比来缩小图片

image.ScalePercent(percentage * 100);

//gzX居左的距离 gzY居底的距离

int gzX = Int32.Parse(ReportPage.GetSession("gzX"));

int gzY = Int32.Parse(ReportPage.GetSession("gzY"));

image.SetAbsolutePosition(gzX, gzY);

document.Add(image);
