- Description
The TDx_Draw::CreatePalette method will create a palette to be used by the TDx_Draw component calling this method.
If the method call fails, the OnError event will be triggered with one of the following values:
DDERR_INVALIDOBJECT
DDERR_INVALIDPARAMS
DDERR_NOCOOPERATIVELEVELSET
DDERR_OUTOFMEMORY
DDERR_UNSUPPORTED
- Parameters
Flags
The Flags parameter defines flags indicating the type of index used to access the created palette's color table.
The described effect applies when the flag is set.
-
DDPCAPS_1BIT
The palette index will be 1 bit.
There will be 2 entries in the color table.
DDPCAPS_2BIT
The palette index will be 2 bits.
There will be 4 entries in the color table.
DDPCAPS_4BIT
The palette index will be 4 bits.
There will be 16 entries in the color table.
DDPCAPS_8BIT
The palette index will be 8 bits.
There will be 256 entries in the color table.
DDPCAPS_8BITENTRIES
The palette index will reference an 8 bit color index.
This flag is only valid when one of the DDPCAPS_1BIT, DDPCAPS_2BIT or DDPCAPS_4BIT flags are set and the surface which is to use the new palette has a bit depth of 8.
Each color entry is an 8 bit index into the destination surface's 8 bpp palette.
DDPCAPS_ALLOW256
All 256 entries of the created palette may be accessed.
Entry 0 and entry 255 on 8-bit palettes are reserved for system use unless this flag is set.
DDPCAPS_ALPHA
The peFlags member of the associated PALETTEENTRY structure is to be interpreted as an 8-bit alpha value.
Palettes with this capability may only be attached to textures.
DDPCAPS_INITIALIZE
The palette is to be initialized with the colors referenced by the ColorArray parameter of this method.
DDPCAPS_PRIMARYSURFACE
The palette is attached to the primary surface.
Changes to the palette will have an immediate effect on the display unless the DDPCAPS_VSYNC capability is specified and supported.
DDPCAPS_PRIMARYSURFACELEFT
The palette is attached to the primary surface for the left eye.
Changes to the palette will have an immediate effect on the left eye display unless the DDPCAPS_VSYNC capability is specified and supported.
DDPCAPS_VSYNC
The palette can be modified synchronously with the monitor's refresh rate.
The ColorArray parameter references an array of 2, 4, 16, or 256 PALETTEENTRY structures used to initialize the palette being created.
Palette
The Palette parameter will reference the new palette if this method returns successfully.
