void pdftron::PDF::Reflow::Destroy | ( |  | ) |

UString pdftron::PDF::Reflow::GetAnnot | ( | UString | in_id | ) |

void pdftron::PDF::Reflow::SetDoNotReflowTextOverImages | ( | bool | do_not_reflow_text_over_images | ) |

Determines whether to not reflow text that appears over images. Default is false.

Parameters

  do_not_reflow_text_over_images | – if true, text that appears over images will not be included in the output HTML.

void pdftron::PDF::Reflow::SetFontOverrideName | ( | UString | font_family | ) |

Overrides the font to use for reflowed content. If this property is empty, the default PDF font will be used. Default is no override.

Parameters

  font_family | – the font-family value that goes to the CSS in the output HTML.

If SetHideImagesUnderInvisibleText() is set to true while SetHideImagesUnderText() is set to false, then images that are covered by invisible text will not be included in the output HTML. This can be useful when processing scanned documents that are processed by OCR.

Parameters

  hide_images_under_invisible_text | – if true, images that are covered by invisible text will not be included in the output HTML.

void pdftron::PDF::Reflow::SetHideImagesUnderText | ( | bool | hide_images_under_text | ) |

Determines whether to hide images that are covered by text. Default is false.

Parameters
