How to set background image in PdfPCell in iText?
I am currently using iText to generate PDF reports. I want to set a medium size image as a background in PdfPCell
instead of using background color. Is this possible?

There is no PdfPCell
class in iText 7. You should use Cell
instead. To set your own custom background you need to extend CellRenderer
and override draw()
method like this:
private class ImageBackgroundCellRenderer extends CellRenderer {
protected Image img;
public ImageBackgroundCellRenderer(Cell modelElement, Image img) {
super(modelElement);
this.img = img;
}
@Override
public void draw(DrawContext drawContext) {
img.scaleToFit(getOccupiedAreaBBox().getWidth(), getOccupiedAreaBBox().getHeight());
drawContext.getCanvas().addXObject(img.getXObject(), getOccupiedAreaBBox());
super.draw(drawContext);
}
}
Then you should create an instance of this renderer and declare it to the cell that needs this background:
Image img = new Image(ImageDataFactory.create(IMG));
// Draws an image as the cell's background
cell.setNextRenderer(new ImageBackgroundCellRenderer(cell, img));
Take a look at the ImageBackground example for the full code.
