NAME
LoadRGB4 -- Load RGB color values from table.
SYNOPSIS
LoadRGB4( vp, colors , count )
a0 a1 d0:16
void LoadRGB4( struct ViewPort *, UWORD *, WORD);Links: ViewPort
FUNCTION
load the count words of the colormap from table starting at entry 0.
INPUTS
vp - pointer to ViewPort, whose colors you wish to change colors - pointer to table of RGB values set up as an array of USHORTS background-- 0x0RGB color1 -- 0x0RGB color2 -- 0x0RGB etc. UWORD per value. The colors are interpreted as 15 = maximum intensity. 0 = minimum intensity. count = number of UWORDs in the table to load into the colormap starting at color 0(background) and proceeding to the next higher color number
RESULTS
The ViewPort should have a pointer to a valid ColorMap to store the colors in. Updates the hardware copperlist to reflect the new colors. Updates the intermediate copperlist with the new colors.
BUGS
NOTE: With V36 and up, it is not safe to call this function from an interrupt, because of the semaphore locking on graphics copper lists.
