The TDx_DrawPalette::GetCaps method will return the palette capabilities.

If the method call fails, the OnError event will be triggered with one of the following values:
DDERR_INVALIDOBJECT
DDERR_INVALIDPARAMS

Caps
The Caps parameter will reference the palette capabilities if this method returns successfully.
The described effect applies when the flag is set.
These flags are the same as those listed for TDDCaps::PalCaps.
DDPCAPS_1BIT

There will be 2 color table entries.

DDPCAPS_2BIT

There will be 4 color table entries.

DDPCAPS_4BIT

There will be 16 color table entries.

DDPCAPS_8BIT

There will be 256 color table entries.

DDPCAPS_8BITENTRIES
The palette index is an index to a 8-bit color index.
This flag is only valid when the target surface is 8 bpp and either DDPCAPS_1BIT, DDPCAPS_2BIT or DDPCAPS_4BIT is set. Color entries are 8 bits and are indexes into the 8 bpp palette of the destination surface.

DDPCAPS_ALLOW256
The palette can have all 256 entries specified by the application.
Entry 0 and entry 255 on 8-bit palettes are reserved for system use unless this flag is set.

The palette is attached to the primary surface.
Changes to the palette will be immediately apparent on the display unless DDPCAPS_VSYNC is set and supported.
