struct ITab { SInt32 iTabSeed; SInt16 iTabRes; Byte iTTable[1]; }; typedef ITab ITabPtr;
The iTabSeed value, initially set from the corresponding CLUTs ctSeed field. If at any time these do not match, then the color table was changed, and the inverse table needs to be rebuilt.
The resolution of this inverse table.
An array of index values. The size of the iTabTable field in bytes is 23*iTabRes.
The ITab data structure contains the inverse table information that the Color Manager uses for fast mapping of RGB color values.
