it is at +least 32. +.bp +.TS +center tab(:) delim($$) ; +lb cb cb cb cb +l c c c c. +_ +_param1:Lookup Index:Lookup Value:Initial Size:Initial Value +_ +_const(PIXEL_MAP_I_TO_I):color index:color index:1:0 +_const(PIXEL_MAP_S_TO_S):stencil index :stencil index :1:0 +_const(PIXEL_MAP_I_TO_R):color index :R:1:0 +_const(PIXEL_MAP_I_TO_G):color index :G:1:0 +_const(PIXEL_MAP_I_TO_B):color index:B:1:0 +_const(PIXEL_MAP_I_TO_A):color index:A:1:0 +_const(PIXEL_MAP_R_TO_R):R:R:1:0 +_const(PIXEL_MAP_G_TO_G):G:G:1:0 +_const(PIXEL_MAP_B_TO_B):B:B:1:0 +_const(PIXEL_MAP_A_TO_A):A:A:1:0 +_ +.TE + +.RE +.SH ERRORS +_const(INVALID_ENUM) is generated if _param1 is not an accepted value. +.P +_const(INVALID_VALUE) is generated if _param2 is less than one +or larger than _const(MAX_PIXEL_MAP_TABLE). +.P +_const(INVALID_VALUE) is generated if _param1 is +_const(PIXEL_MAP_I_TO_I), +_const(PIXEL_MAP_S_TO_S), +_const(PIXEL_MAP_I_TO_R), +_const(PIXEL_MAP_I_TO_G), +_const(PIXEL_MAP_I_TO_B), or +_const(PIXEL_MAP_I_TO_A), +and _param2 is not a power of two. +.P +_const(INVALID_OPERATION) is generated if _cmnd +is executed between the execution of _cmnd(Begin) +and the corresponding execution of _cmnd(End). +.SH ASSOCIATED GETS +_cmnd(GetPixelMap) +.br +_cmnd(Get) with argument _const(PIXEL_MAP_I_TO_I_SIZE) +.br +_cmnd(Get) with argument _const(PIXEL_MAP_S_TO_S_SIZE) +.br +_cmnd(Get) with argument _const(PIXEL_MAP_I_TO_R_SIZE) +.br +_cmnd(Get) with argument _const(PIXEL_MAP_I_TO_G_SIZE) +.br +_cmnd(Get) with argument _const(PIXEL_MAP_I_TO_B_SIZE) +.br +_cmnd(Get) with argument _const(PIXEL_MAP_I_TO_A_SIZE) +.br +_cmnd(Get) with argument _const(PIXEL_MAP_R_TO_R_SIZE) +.br +_cmnd(Get) with argument _const(PIXEL_MAP_G_TO_G_SIZE) +.br +_cmnd(Get) with argument _const(PIXEL_MAP_B_TO_B_SIZE) +.br +_cmnd(Get) with argument _const(PIXEL_MAP_A_TO_A_SIZE) +.br +_cmnd(Get) with argument _const(MAX_PIXEL_MAP_TABLE) +.SH SEE ALSO +_cmnd(ColorTable), +_cmnd(ColorSubTable), +_cmnd(ConvolutionFilter1D), +_cmnd(ConvolutionFilter2D), +_cmnd(CopyPixels), +_cmnd(CopyTexImage1D), +_cmnd(CopyTexImage2D), +_cmnd(CopyTexSubImage1D), +_cmnd(CopyTexSubImage2D), +_cmnd(DrawPixels), +_cmnd(Histogram), +_cmnd(Minmax), +_cmnd(PixelStore), +_cmnd(PixelTransfer), +_cmnd(ReadPixels), +_cmnd(SeparableFilter2D), +_cmnd(TexImage1D), +_cmnd(TexImage2D), +_cmnd(TexImage3D), +_cmnd(TexSubImage1D), +_cmnd(TexSubImage2D), +_cmnd(TexSubImage3D) |
