PdfFontEmbeddingRights Enum
Represents the font embedding licensing rights for the PdfFontFace. Valid fonts must set at most one of Installable, RestrictedLicense, PreviewAndPrint or Editable.
Remarks
Embeddable fonts may be stored in a document. When a document with embedded fonts is opened on a system that does not have the font installed (the remote system), the embedded font may be loaded for temporary (and in some cases, permanent) use on that system by an embedding-aware application. Embedding licensing rights are granted by the vendor of the font.
important
Applications that implement support for font embedding must not embed fonts which are not licensed to permit embedding. Also, when embedding a font into a document, applications must not modify the embedding permissions and restrictions. In addition, applications loading embedded fonts for temporary use (PreviewAndPrint or Editable embedding) must delete the fonts when the document containing the embedded font is closed.
Installable, RestrictedLicense, PreviewAndPrint and Editable fields are mutually exclusive: fonts should never have more than of these fields set. Note that, if two or more bits are set, some applications could assume the least-restrictive permission indicated.
important
GemBox.Pdf ignores the EmbeddingRights, so it is the application developer's responsibility to perform the font licensing rights check. If in doubt, contact the font's vendor.
Fields
| BitmapsOnly | Only bitmaps contained in the font may be embedded. No outline data may be embedded. If there are no bitmaps available in the font, then the font is considered unembeddable and the embedding services will fail. Other embedding restrictions specified in Installable, RestrictedLicense, PreviewAndPrint, Editable, and NoSubsetting also apply. |
| Editable | The font may be embedded, and may be temporarily loaded on other systems. As with PreviewAndPrint embedding, documents containing Editable fonts may be opened for reading. In addition, editing is permitted, including ability to format new text using the embedded font, and changes may be saved. |
| Installable | The font may be embedded, and may be permanently installed for use on a remote systems, or for use by other users. The user of the remote system acquires the identical rights, obligations and licenses for that font as the original purchaser of the font, and is subject to the same end-user license agreement, copyright, design patent, and/or trademark as was the original purchaser. |
| NoSubsetting | The font may not be subsetted prior to embedding. Other embedding restrictions specified in Installable, RestrictedLicense, PreviewAndPrint, Editable, and BitmapsOnly also apply. |
| PreviewAndPrint | The font may be embedded, and may be temporarily loaded on other systems for purposes of viewing or printing the document. Documents containing PreviewAndPrint fonts must be opened "read-only"; no edits can be applied to the document. |
| RestrictedLicense | The font must not be modified, embedded or exchanged in any manner without first obtaining explicit permission of the legal owner. |
