推荐答案

当然，您的内容被裁剪掉了，这就是您告诉它要做的.您还需要缩小内容，在页面内容流之前添加缩放矩阵:

Of course your content is cropped off, that's what you told it to do. You need to shrink the content too, be prepending a scaling matrix to the page content stream:

    if (reSizepage != null)
    {
        reSizepage.setMediaBox(mediaBox);

        PDPageContentStream contentStream = new PDPageContentStream(document, reSizepage, PDPageContentStream.AppendMode.PREPEND, false);
        contentStream.transform(Matrix.getScaleInstance(0.9f, 0.9f));
        contentStream.close();
    }
