  • Method Details

    • notSet

      @Deprecated public boolean notSet(String key)
      Deprecated.
      - kept for backwards code support (do not use)
      Parameters:
      key - is of type String.
      Returns:
      boolean used internally to show if valid.

    • setRealPageRange

      public ConversionOptions setRealPageRange(PageRanges value)
      Set a page range using real page numbering. This setting treats the document as if it contains every page, however only the pages defined in the range will be converted.

      For example, a 7-page document with the page range "2,4,6" will generate 2.html, 4.html and 6.html, and other assets will behave as if pages 1, 3, 5 also 7 exist.

      Important: Some assets such as config.js/properties.json/annotations.json/search.json/index.html may not be compatible with this setting.

      Possible values:

      • Comma separated values including ranges. E.g. "1,3,5-8,10"

      Default value: all pages, e.g. "1-39"

      Also set with -Dorg.jpedal.pdf2html.realPageRange=

      Parameters:
      value - is of Object type PageRanges.
      Returns:
      the ConversionOptions Object.

    • setLogicalPageRange

      public ConversionOptions setLogicalPageRange(PageRanges value)
      Set a page range using logical page numbering. This setting treats the document as if it only contains the pages defined in the page range.

      For example, a 7-page document with the page range "2,4,6" will generate 1.html, 2.html and 3.html, and other assets will behave as if only these pages exist.

      Important: Some assets such as config.js/properties.json/annotations.json may not be compatible with this setting.

      Possible values:

      • comma separated values including ranges. E.g. "1,3,5-8,10"

      Default: null

      Also set with -Dorg.jpedal.pdf2html.logicalPageRange=

      Parameters:
      value - is of Object type PageRanges.
      Returns:
      the ConversionOptions Object.

    • setOmitNameDir

      public ConversionOptions setOmitNameDir(boolean b)
      Controls the folder structure of the output.

      By default, pages are output within a directory with the same name as the PDF file within the output directory specified.

      Setting omitNameDir to true will cause pages to be output directly within the output directory specified. Possible values:

      • true/false

      Default: false

      Also set with -Dorg.jpedal.pdf2html.omitNameDir=

      Parameters:
      b - Boolean true/false.
      Returns:
      the ConversionOptions Object.

    • setCompressSVG

      public ConversionOptions setCompressSVG(boolean b)
      Generates compressed .svgz files rather than .svg (you will need to configure your web server to correctly serve these).

      It is recommended to enable this setting as svg file sizes can be reduced by as much as 80-90%!

      SVGZ files are simply SVG files which have been gzip compressed. Gzip compressed svg files are supported by all modern browsers (IE9 onwards, Firefox, Chrome, etc) as long as the web server is configured correctly.

      Possible values:

      • true/false

      Default: false

      Also set with -Dorg.jpedal.pdf2html.compressSVG=

      Parameters:
      b - Boolean true/false.
      Returns:
      the ConversionOptions Object.

      Pages larger than the given dimensions will be scaled down to fit within those dimensions. Pages smaller than the given dimensions will be unaffected.

      This setting may be useful to prevent rogue documents with unusually large pages from causing OutOfMemoryErrors (which may otherwise bring down the JVM).

      Possible value:

      • true/false

      Default: false

      Also set with -Dorg.jpedal.pdf2html.useLegacyImageFileType=

      Parameters:
      value - is of type boolean.
      Returns:
      the ConversionOptions Object.

    • setCompressImages

      public ConversionOptions setCompressImages(boolean value)
      When enabled, generated PNG images will be compressed to reduce file size.

      This setting has an effect only when svg text modes are used, or when setUseLegacyImageFileType is set to true.

      Rather than producing 24 bit RGB or 32 bit RGBA truecolor PNG images, instead the converter will produce 8 bit palette images that have undergone quantization and dithering. This is a lossy compression, but visual quality remains very high.

      Enabling compression will make conversion slower. On average, expect conversion time to at least double. File size saving can be significant. On files with large images, it is not unusual to see savings of 70-80% on the image file size.

      Possible value:

      • true/false

      Default: true

      Also set with -Dorg.jpedal.pdf2html.compressImages=

      Parameters:
      value - is of type boolean
      Returns:
      the ConversionOptions Object.

    • setImageScale

      public ConversionOptions setImageScale(float imageScale)
      Write out larger images to allow higher quality zooming.

      Default value is 1, which produces images at the same size they are displayed when the zoom is 100%. A value of 1.5 will generate images at 1.5x the standard size. The maximum size of an image is capped at the size of the source image stored in the PDF file. For example if the source image is 150x150, then increasing the imageScale value will not generate an image larger than 150x150.

      It is important to remember that file size grows exponentially with the scaling factor. For example, scaling an image by 2 actually multiplies the number of pixels by 4. We therefore recommend a value such as 1.5 or 2.

      Possible values:

      • Float value greater than 1 e.g. 1.5, 2

      Default: 1

      Also set with -Dorg.jpedal.pdf2html.imageScale=

      Parameters:
      imageScale - is of type float
      Returns:
      the ConversionOptions Object.

    • setPageFlatteningImageThreshold

      public ConversionOptions setPageFlatteningImageThreshold(int threshold)
      Set the threshold for the number of images which, once reached, will cause the page will be flattened into a single image to improve performance in the browser.

      Possible values:

      • Any positive integer value

      Default: 200

      Also set with -Dorg.jpedal.pdf2html.pageFlatteningImageThreshold=

      Parameters:
      threshold - the threshold at which the page will be flattened
      Returns:
      the ConversionOptions Object.

    • setClipOffsetAmount

      public ConversionOptions setClipOffsetAmount(float offsetAmount)
      Set the distance in pixels that polygons are expanded by in order to reduce fractional white lines

      Possible values:

      • Any floating point value

      Default: 0.3

      Also set with -Dorg.jpedal.pdf2html.clipOffsetAmount=

      Parameters:
      offsetAmount - the distance in pixels to expand the clip edges by
      Returns:
      the ConversionOptions Object.

    • setOriginalFileName

      public ConversionOptions setOriginalFileName(String originalFileName)
      Spoof the filename of the document being converted. This setting is useful when the filename is not specified such as when converting from InputStream or byte array, or when the filename has been sanitized.

      This value controls the following:

      • The name of the output directory (sanitized)
      • The title used by the IDRViewer (when a title is not defined within the PDF file)
      • In FormVu, the filename used when resaving the form as PDF
