VgetRGB()                                                             XBIOS

Syntax

VOID VgetRGB( index, count, rgb )
WORD index, count;
RGB *rgb;

Function      VgetRGB() returns palette information as 24-bit RGB data.

Opcode        94 (0x5E)

Availability  Available if the '_VDO' cookie has a value of 0x00030000 or
              greater.

Parameters    index specifies the beginning color index in the palette to
              read data from. count specifies the number of palette
              entries to read. rgb is a pointer to an array of RGBs which
              will be filled in by the functions. RGB is defined as:

              typedef struct
              {
               BYTE reserved;
               BYTE red;
               BYTE green;
               BYTE blue;
              } RGB;

Binding       pea      rgb
              move.w   count,-(sp)
              move.w   index,-(sp)
              move.w   #$5E,-(sp)
              trap     #14
              lea      10(sp),sp

Comments      VgetRGB() is device-dependent in nature and it is therefore
              recommended that vq_color() be used instead.
