我正在尝试将尺寸= 2496 x 3512的图像缩放为PDF文档.我正在使用PDFBox生成它,但缩放的图像最终模糊.

以下是一些片段:

• PDF页面大小(A4)由page.findMediaBox()返回.createDimension():java.awt.Dimension [width = 612,height = 792]

• 然后我根据页面大小与图像大小计算缩放维度,返回:java.awt.Dimension [width = 562,height = 792]我使用下面的代码来计算缩放维度:

  public static Dimension getScaledDimension(Dimension imgSize, Dimension boundary) {
    int original_width = imgSize.width;
    int original_height = imgSize.height;
    int bound_width = boundary.width;
    int bound_height = boundary.height;
    int new_width = original_width;
    int new_height = original_height;
  
    // first check if we need to scale width
    if (original_width > bound_width) {
      //scale width to fit
      new_width = bound_width;
      //scale height to maintain aspect ratio
      new_height = (new_width * …
