如何使用 java 中的 pdfbox 从 pdf 获取图像坐标

Question

I want to get image field from existing pdf and fill it with other image to create new pdf file using pdfbox library in java

Answer 1

If your trying to get image coordinates from a PDF you could try PDF Mantis which has a function to extract this information - See example below:

// Load your PDF
PdfMantis pdf = new PdfMantis("/home/example.pdf");

// Get the image index
List <ImageIndex> imageIndex = pdf.getImageIndex().buildIndex();

// Iterate over each entry in the index
for (ImageIndex image : imageIndex) {

    // And then we can get coordinates like so...
    image.getX();
    image.getY();
    image.getHeight();
    image.getWidth();
}
