Pattern Off Color CIELab Value Attribute

Tag(0070,0252)
TypeOptional (3)
KeywordPatternOffColorCIELabValue
Value Multiplicity3
Value RepresentationUnsigned Short (US)

A color triplet value used to encode the color of parts of the line that are off, i.e., the background. The units are specified in PCS-Values, and the value is encoded as CIELab. See Section C.10.7.1.1.

Section C.10.7.1.1

C.10.7.1.1 Encoding of CIELab Values

Attributes such as Graphic Layer Recommended Display CIELab Value (0070,0401) consist of three unsigned short values:

  • An L value linearly scaled to 16 bits, such that 0x0000 corresponds to an L of 0.0, and 0xFFFF corresponds to an L of 100.0.

  • An a* then a b* value, each linearly scaled to 16 bits and offset to an unsigned range, such that 0x0000 corresponds to an a* or b* of -128.0, 0x8080 corresponds to an a* or b* of 0.0 and 0xFFFF corresponds to an a* or b* of 127.0

Note

This is the same form of encoding as used for the PCS in ICC Profiles.
