Configure the Size of Exported Images

When you use the pdf2sr reader to export images of the pages in a PDF file, you can configure the size of the images produced by KeyView.

NOTE: When a page in a PDF document consists of a single embedded image (such as when the PDF is a scanned document), the page image is output at the original size of the embedded image and the following settings have no effect.

To configure the size of images produced by pdf2sr

  1. Open the configuration file formats_e.ini.
  2. Find the section [pdf2sr], or create the section if it does not exist.
  3. Set the configuration parameters XMLXRes and XMLYRes. XMLXRes specifies the width of the output image and XMLYRes specifies the height.

    • To specify an absolute size, in pixels, use positive values. The aspect ratio is always maintained, so you can set one of the dimensions and set the other parameter to 0. For example, to output images of PDF pages where the height of each image is 400 pixels, use the following configuration:

      [pdf2sr]
      XMLXRes=0
      XMLYRes=400

      If you set both XMLXRes and XMLYRes to positive values, KeyView produces the largest image that fits within the specified dimensions (the width or height will be as requested, and the other dimension is smaller than requested if required to preserve the aspect ratio).

    • To specify a relative size, set XMLXRes to a negative value and XMLYRes to 0 (a negative value for XMLYRes is ignored). The aspect ratio is always maintained. For example, to output images of PDF pages where the size of each image is 150% of the original size, use the following configuration.

      [pdf2sr]
      XMLXRes=-150
      XMLYRes=0

NOTE: The default values for XMLXRes and XMLYRes are shown below. These values produce an image at 113% of the original page size:

[pdf2sr]
XMLXRes=-113
XMLYRes=0
