这个table的8位和16位编码到底包含了什么？
What is contained in this table of 8-bit and 16-bit encodings?
我正在尝试读取一个包含 8 位无符号整数值的文件。在 file description document, Table 70 (below) describes how you get from the 8-bit value to the desired value (known as a* or b*). But I can't figure out what's in the 2nd column under "8 bit". What is 00h, 80h, or FFh? Is this some kind of code? From here 中它们看起来像是数字：0、128 和 255，但是它们在 table 中的格式是什么？
好的，我知道的更多一些：这些值是十六进制（以 16 为底），可以转换为十进制 here. Some background here if, like me, you are unfamiliar with them. I will add that this is related to reading in L* a* b* values from CIELab format Tiff files，以防其他人尝试这样做。
