itext image to pdf 大小設定

Document document = new Document();
String filePath = "D:/J089/J089-workspace/SimpleTest/pdf/temp/tmp.pdf";

PdfWriter.getInstance(document, new FileOutputStream(filePath));

document.open();
Image image1 = Image.getInstance(imgPath);


方法一：

float pageWidth = document.getPageSize().getWidth();
float leftMargin = document.leftMargin();
float rightMargin = document.rightMargin();
float imageWidth = image1.getWidth();

float scaler = (( pageWidth - leftMargin - rightMargin ) / imageWidth ) * 100;

image1.scalePercent(scaler);

方法二：

float documentWidth = document.getPageSize().getWidth() - document.leftMargin() - document.rightMargin();

float documentHeight = document.getPageSize().getHeight() - document.topMargin() - document.bottomMargin();

image1.scaleToFit(documentWidth, documentHeight);

document.add(image1);

document.close();
