Enum CicpTransferCharacteristics

Namespace

PaintDotNet.Imaging

Assembly

PaintDotNet.Windows.Core.dll

Identifies the opto-electronic / electro-optical transfer characteristic (the "gamma" or EOTF) of the source. These are the "TransferCharacteristics" code points defined by ITU-T H.273 (Table 3) and used by the PNG cICP chunk.

public enum CicpTransferCharacteristics : byte

Fields

Bt709 = 1

Rec. ITU-R BT.709-6. (Functionally identical to Bt601, Bt2020TenBit, and Bt2020TwelveBit.)

Unspecified = 2

Unspecified. The transfer characteristic is determined by the application or by other means.

Gamma22 = 4

Rec. ITU-R BT.470-6 System M (historical); assumed display gamma of 2.2.

Gamma28 = 5

Rec. ITU-R BT.470-6 System B, G (historical); assumed display gamma of 2.8.

Bt601 = 6

Rec. ITU-R BT.601-7 525 or 625; BT.1358; BT.1700; SMPTE ST 170.

Smpte240M = 7

SMPTE ST 240 (historical).

Linear = 8

Linear transfer characteristics.

Log100 = 9

Logarithmic transfer characteristic (100:1 range).

Log100Sqrt10 = 10

Logarithmic transfer characteristic (100 * Sqrt(10) : 1 range).

Iec6196624 = 11

IEC 61966-2-4 (xvYCC).

Bt1361 = 12

Rec. ITU-R BT.1361-0 extended colour gamut system (historical).

Srgb = 13

IEC 61966-2-1 (sRGB or sYCC).

Bt2020TenBit = 14

Rec. ITU-R BT.2020-2 for a system using 10-bit precision. (Same function as Bt709.)

Bt2020TwelveBit = 15

Rec. ITU-R BT.2020-2 for a system using 12-bit precision. (Same function as Bt709.)

SmpteSt2084PQ = 16

SMPTE ST 2084 for 10-, 12-, 14-, and 16-bit systems; Rec. ITU-R BT.2100-2 perceptual quantization (PQ).

SmpteSt428 = 17

SMPTE ST 428-1.

AribStdB67Hlg = 18

ARIB STD-B67; Rec. ITU-R BT.2100-2 hybrid log-gamma (HLG).

Remarks

The underlying type is byte to match the 8-bit code point in the cICP chunk. Only the values defined by H.273 are named here; reserved and unassigned values (0, 3, and 19–255) are intentionally not enumerated, but still round-trip faithfully because the storage type is a raw byte.
