GetCTable

Allocate and initialize a new color table data structure

#include <Quickdraw.h> Color QuickDraw

short ctID ; ID of desired color table resource

returns CTabHandle leading to the color table's data structure

GetCTable obtains a new color table data structure and initializes it from

data in the 'clut' resources for that specific ID.

ctID is the identifier of the desired color table resource.

Returns: a CTabHandle leading to the specified resource. If the

resource ID ctID can't be found, the return value is NIL.

Notes: Dispose of any old handles in a PixMap before putting a new CTabHandle

into it. All of your application's 'clut' ID values have to be above 128 and

below 1024. Anything from 0 to 127 has already been reserved.

Values used by your application must be in the ctSeed field in the resource

and Color QuickDraw will put them in the ctSeed field of the color table.

Every other seed value is used to identify new or newly modified color

tables.

Invalidate a modified color table by changing its ctSeed field. Use

GetCTSeed to get a new value for the ctSeed of the changed color table.
