Thumbnail Generation

PDF Highlighter can generate page thumbnails as a part of document indexing process.

highlighter {
  indexing {
    buildPageThumbs = [
      {
        page = 1        # document page for which to generate the thumbnail (default is 1)
        scale = 1       # scale factor (default is 1)
        format = "png"  # image format (default is "png")
        width = 170     # max width
        height = 240    # max height
        filepath = "/my/thumbs/{docId}.{format}"   # image path and file naming scheme
      }
    ]
  }
}

The following variables can be used in the filepath:

docId - Internal document identifier generated by Highlighter
docCachePath - Path to document cache folder
