SetPaletteDataExt

Programs the hardware color palette using 16-bit per color channel

Declaration

void NAPI GA_driverFuncs::SetPaletteDataExt(
GA_paletteExt *pal,
N_int32 num,
N_int32 index,
N_int32 waitVRT)

Prototype In

snap/graphics.h

Parameters

pal | Pointer to the extended palette data to program
num | Number of palette entries to program
index | Index of first entry to program
waitVRT | Wait for vertical retrace flag

Description

This function programs the color palette information for the current graphics mode, and is only valid in 8-bpp and lower color index modes. Color palette information is passed to the function in an array of GA_paletteExt structures. Each value in the GA_paletteExt structure is 16-bits wide, with a range of 0 to 65535. Note that this is different to the regular SetPaletteData function, which takes 8-bit wide values. Internally the driver will convert the 16-bit palette values to 8-bits if this is what the underlying hardware supports.

This function is basically the same as SetPaletteData except it deals with a palette with 16-bit color values per channel.
