_i_n_p_u_t_U_s_a_g_e Specifies the modes in which the destination field buffers
(ffffiiiieeeellllddddAAAA and ffffiiiieeeellllddddBBBB) will be used as input; says how the
image will be read from the buffers and used as input to a
plug-in or application. The value is a bitwise combination
of one or more of: bbbbuuuuffffIIIInnnnppppuuuuttttDDDDiiiirrrreeeecccctttt, bbbbuuuuffffIIIInnnnppppuuuuttttTTTTeeeexxxxttttuuuurrrreeee,
bbbbuuuuffffIIIInnnnppppuuuuttttDDDDrrrraaaawwwwPPPPiiiixxxxeeeellllssss, bbbbuuuuffffIIIInnnnppppuuuuttttMMMMoooovvvviiiieeee. The options set must
include all of the different ways in which ffffiiiieeeellllddddAAAA and ffffiiiieeeellllddddBBBB
will be used.
_s_r_c_F_r_a_m_e The source frame to copy scanlines from. The even numbered
scanlines (counting from 0) will be copied to ffffiiiieeeellllddddAAAA, and
the odd numbered scanlines will be copied to ffffiiiieeeellllddddBBBB.
_f_i_e_l_d_A The "top-most" field.
_f_i_e_l_d_B The "bottom-most" field.
DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN
ddddmmmmFFFFXXXXSSSSpppplllliiiittttFFFFiiiieeeellllddddssss will create two fields from a single frame. The source
frame buffer must be twice the height of the two field buffers (see
mmmmFFFFXXXXAAAAllllllllooooccccaaaatttteeeeIIIImmmmaaaaggggeeeeBBBBuuuuffffffffeeeerrrrssss), and the source frame width must match the width
of the two field buffers.
The scanlines from the source frame are split out into two field buffers.
The even numbered scanlines (counting from 0) from the source frame
(ssssrrrrccccFFFFrrrraaaammmmeeee) are copied into ffffiiiieeeellllddddAAAA, and the odd numbered scanlines are
copied into ffffiiiieeeellllddddBBBB.
