现在我使用pdfCanvas绘制矩形,代码如下:
PdfPage页面= pdf.getFirstPage();

    PdfCanvas canvas = new PdfCanvas(page, true);
    float x = 35;
    float y = 480;
    canvas.rectangle(x, y, 30, 30).stroke();

实际上,我想将矩形添加到表格中
 Table table = new Table(2);
    table.setWidth(261.5f);

iText 5,可以将画布设置为图像对象并添加到表格中。但是在iText 7中,该功能不起作用。如何在iText7中将图片绘制到表格上?

最佳答案

您可以从独立的PdfCanvas创建XObject,将其转换为XObject,然后将Image添加到Image:

    Rectangle boundingBox = new Rectangle(20,470,50,50);
    PdfFormXObject xObject = new PdfFormXObject(boundingBox);
    xObject.makeIndirect(pdfDoc);//Make sure the XObject gets added to the document
    PdfCanvas canvas = new PdfCanvas(xObject, pdfDoc);//Create a canvas from the XObject
    canvas.setStrokeColor(Color.BLUE).setLineWidth(3f).rectangle(35, 480, 30, 30).stroke();
    Image rect = new Image(xObject);
    table.addCell(rect);
