Public Methods

public void setConnectHyphens (boolean connect)

Specifies whether hyphens in the PDF should be connected. Default is false. Note: This option is only available for e_reflow_paragraphs and e_reflow_full modes.

Parameters
connect if true, hyphens in the PDF will be connected.
Throws
PDFNetException

public void setContentReflowSetting (int reflow)

Switch between fixed (pre-paginated) and reflowable HTML generation. Default is e_fixed_position. In e_reflow_paragraphs mode (now deprecated), conversions require that the optional PDFTron HTML reflow paragraphs add-on module is available. In e_reflow_full mode, conversions require that the optional PDFTron StructuredOutput add-on module is available.

Parameters
reflow the generated HTML will be either fixed or reflowable.
Throws
PDFNetException
PDFNetException

public void setDPI (int dpi)

The output resolution, from 1 to 1000, in Dots Per Inch (DPI) at which to render elements which cannot be directly converted. Default is 140. Note: This option is only available for e_fixed_position mode.

Parameters
dpi the resolution in Dots Per Inch
Throws
PDFNetException

public void setDisableVerticalSplit (boolean disable)

Specifies whether to disable the detection of section columns. Default is false. Enable this if your tables are coming out as section columns. Note: This option is only available for e_reflow_paragraphs mode. In e_reflow_full mode, columns are detected automatically.

Parameters
disable if true, the detection of section columns are disabled.
Throws
PDFNetException

public void setEmbedImages (boolean embed)

Specifies whether images are embedded in the HTML without having to link to external files. Default is true. Note: This option is only available for e_reflow_paragraphs and e_reflow_full modes.

Parameters
embed if true, images are embedd in the HTML, otherwise, images are saved as external files.
Throws
PDFNetException

public void setExternalLinks (boolean enable)

Enable the conversion of external URL navigation. Default is false. Note: This option is only available for e_fixed_position mode.

Parameters
enable if true, links that specify external URL's are converted into HTML.
Throws
PDFNetException

public void setFileConversionTimeoutSeconds (int seconds)

Specifies the amount of time in seconds after which the conversion fails. Default is 300. Very long files need more time to convert. Note: This option is only available for e_reflow_paragraphs mode. The timeout feature is not necessary in other modes.

Parameters
seconds the timeout in seconds.
Throws
PDFNetException

public void setImageDPI (int dpi)

Specifies the output image resolution, from 8 to 600, in Pixels Per Inch (PPI). The higher the PPI, the larger the image. Default is 192. Note: This option is only available for e_reflow_paragraphs mode. In other modes, image resolution is determined automatically for an optimal result.

Parameters
dpi the resolution in Pixels Per Inch.
Throws
PDFNetException

public void setInternalLinks (boolean enable)

Enable the conversion of internal document navigation. Default is false. Note: This option is only available for e_fixed_position mode.

Parameters
enable if true, links that specify page jumps are converted into HTML.
Throws
PDFNetException

public void setJPGQuality (int quality)

Specifies the compression quality to use when generating JPEG images. Note: This option is only available for e_fixed_position and e_reflow_paragraphs modes. In e_reflow_full mode, the optimal JPEG quality is chosen automatically for best balance between size and quality.

Parameters
quality the JPEG compression quality, from 0(highest compression) to 100(best quality).

PDFNetException

public void setLanguage (Convert.OutputOptionsOCR.LanguageChoice language)

Specifies the OCR language. Default is automatic language detection. Note: This option is only available for e_reflow_full mode.

Parameters
language the OCR language.
Throws
PDFNetException

public void setMaximumImagePixels (int max_pixels)

Specifies the maximum image slice size in pixels. Default is 2000000.

Note: This setting now will no longer reduce the total number of image pixels. Instead a lower value will just produce more slices and vice versa.

Note: Since image compression works better with more pixels a larger max pixels should generally create smaller files. Note: This option is only available for e_fixed_position mode.

Parameters
max_pixels the maximum number of pixels an image can have
Throws
PDFNetException

public void setNoPageWidth (boolean enable)

Determines whether to flow contents across the entire browser window. Default is false. Note: This option is only available for e_reflow_paragraphs mode. In e_reflow_full mode, content always flows across the entire browser window.

Specifies the password if the PDF requires one. Note: This option is only available for e_reflow_paragraphs and e_reflow_full modes.

Parameters
password the PDF password, if required; an empty string otherwise.
