如何获取指定关键字在iText7中的位置？

PdfReader reader = new PdfReader("path/to/your/pdf/file.pdf");

int totalPages = reader.getNumberOfPages();
for (int i = 1; i <= totalPages; i++) {
    PdfPage page = reader.getPage(i);
    // 在每一页中查找关键字的位置
}

TextRenderer renderer = new TextRenderer(page);
List<TextRenderInfo> textInfos = renderer.getTextRenderInfos();
for (TextRenderInfo info : textInfos) {
    String text = info.getText();
    if (text.contains("关键字")) {
        Rectangle2D.Float boundingBox = info.getBoundingBox();
        // 获取关键字的位置信息
        float x = boundingBox.x;
        float y = boundingBox.y;
        float width = boundingBox.width;
        float height = boundingBox.height;
        // 处理关键字的位置信息
    }
}

reader.close();
