vsp_state()                                                             VDI

Syntax

VOID vsp_state( handle, port, film, lightness, interlace, planes, indexes )
WORD handle, port, film, lightness, interlace, planes;
WORD *indexes;

Function      vsp_state() sets the palette driver state.

Opcode        5

Sub-Opcode    93

Availability  Supported by all camera drivers.

Parameters    handle specifies a valid workstation handle. port specifies
              the communication port number of the camera device.
              film specifies the index of the desired type of film (0-4).
              lightness specifies the modification to apply to the
              camera's default f-stop setting (-3-3). A value of 0 uses
              the default setting. A value of -3 results in an exposure of
              half of the default length whereas a value of 3 doubles the
              exposure time. interlace is set to 0 for non-interlaced or 1
              for interlaced output. planes specifies the number of planes
              to output (1-4). indexes points to an array of 16 WORDs
              which define the color codes for the palette.
