Требования Imagick. Можно создавать такие изображения:

beginDocument(40, 30, 40, 30);
 $idg->beginRow();
        $idg->beginColumn(300);
            $idg->image('test_image.jpg');
            $idg->beginBlock()->setLeft(20);
                $idg->text('Figure 1. Dolore eu fugiat nulla pariatur.')
                ->setFont($fontRegular)->setFontSize(14)->setTextColor('#555');
            $idg->endBlock();
        $idg->endColumn();
        $idg->beginColumn(600);
                $idg->text('Lorem ipsum dolor sit amet,
