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.

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 HTMLXRes and HTMLYRes. HTMLXRes specifies the width of the output image and HTMLYRes 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]
      HTMLXRes=0
      HTMLYRes=400

      If you set both HTMLXRes and HTMLYRes 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 HTMLXRes to a negative value and HTMLYRes to 0 (a negative value for HTMLYRes 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]
      HTMLXRes=-150
      HTMLYRes=0

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

[pdf2sr]
HTMLXRes=-113
HTMLYRes=0
