Class LicenseFlags

Represents the embedding and licensing restrictions declared in the OS/2 table's fsType field (OpenType spec §5.7).

Inheritance
object
LicenseFlags
Inherited Members
Namespace: DRIT.Drawing.Font.Core
Assembly: DRIT.Drawing.dll
Syntax
public sealed class LicenseFlags
Remarks

Obtain an instance via TtfOs2Table.GetLicenseFlags(). A null return from that method indicates the OS/2 table is absent. When the instance is non-null but FSTypeAbsent is true, the font declares no embedding restrictions (fsType == 0).

Constructors

LicenseFlags(ushort)

Initializes a new LicenseFlags instance from the specified fsType value.

Declaration
public LicenseFlags(ushort fsType)
Parameters
Type Name Description
ushort fsType

The raw OS/2 fsType value.
Remarks

Obtain an instance via TtfOs2Table.GetLicenseFlags(). A null return from that method indicates the OS/2 table is absent. When the instance is non-null but FSTypeAbsent is true, the font declares no embedding restrictions (fsType == 0).

Properties

BitmapEmbeddingOnly

Bit 9 (mask 0x0200). Only bitmaps contained in the font may be embedded; no outline data may be embedded.

Declaration
public bool BitmapEmbeddingOnly { get; }
Property Value
Type Description
bool
Remarks

Obtain an instance via TtfOs2Table.GetLicenseFlags(). A null return from that method indicates the OS/2 table is absent. When the instance is non-null but FSTypeAbsent is true, the font declares no embedding restrictions (fsType == 0).

FSTypeAbsent

True if fsType == 0, meaning the font declares no embedding restrictions and may be freely embedded.

Declaration
public bool FSTypeAbsent { get; }
Property Value
Type Description
bool
Remarks

Obtain an instance via TtfOs2Table.GetLicenseFlags(). A null return from that method indicates the OS/2 table is absent. When the instance is non-null but FSTypeAbsent is true, the font declares no embedding restrictions (fsType == 0).

FsType

Raw OS/2 fsType value.

Declaration
public ushort FsType { get; }
Property Value
Type Description
ushort
Remarks

Obtain an instance via TtfOs2Table.GetLicenseFlags(). A null return from that method indicates the OS/2 table is absent. When the instance is non-null but FSTypeAbsent is true, the font declares no embedding restrictions (fsType == 0).

IsEditableEmbedding

Bit 3 (mask 0x0008), bits 1–2 clear. The font may be embedded and documents using it may be edited on the target system.

Declaration
public bool IsEditableEmbedding { get; }
Property Value
Type Description
bool
Remarks

Obtain an instance via TtfOs2Table.GetLicenseFlags(). A null return from that method indicates the OS/2 table is absent. When the instance is non-null but FSTypeAbsent is true, the font declares no embedding restrictions (fsType == 0).

IsInstallableEmbedding

No restriction bits (1–3) are set; the font may be permanently installed on target systems (installable embedding).

Declaration
public bool IsInstallableEmbedding { get; }
Property Value
Type Description
bool
Remarks

Obtain an instance via TtfOs2Table.GetLicenseFlags(). A null return from that method indicates the OS/2 table is absent. When the instance is non-null but FSTypeAbsent is true, the font declares no embedding restrictions (fsType == 0).

IsPreviewAndPrintEmbedding

Bit 2 (mask 0x0004), bit 1 clear. The font may be embedded for preview and print but must not be installed on the target system.

Declaration
public bool IsPreviewAndPrintEmbedding { get; }
Property Value
Type Description
bool
Remarks

Obtain an instance via TtfOs2Table.GetLicenseFlags(). A null return from that method indicates the OS/2 table is absent. When the instance is non-null but FSTypeAbsent is true, the font declares no embedding restrictions (fsType == 0).

IsRestrictedLicenseEmbedding

Bit 1 (mask 0x0002). The font must not be modified or embedded in any manner without explicit permission of the legal owner.

Declaration
public bool IsRestrictedLicenseEmbedding { get; }
Property Value
Type Description
bool
Remarks

Obtain an instance via TtfOs2Table.GetLicenseFlags(). A null return from that method indicates the OS/2 table is absent. When the instance is non-null but FSTypeAbsent is true, the font declares no embedding restrictions (fsType == 0).

NoSubsetting

Bit 8 (mask 0x0100). The font may not be subsetted prior to embedding.

Declaration
public bool NoSubsetting { get; }
Property Value
Type Description
bool
Remarks

Obtain an instance via TtfOs2Table.GetLicenseFlags(). A null return from that method indicates the OS/2 table is absent. When the instance is non-null but FSTypeAbsent is true, the font declares no embedding restrictions (fsType == 0).
