85 Specifing DIVE_BUFFER_GRAPHICS_PLANE results in the image being
86 transferred to the graphics plane.
87 Specifing DIVE_BUFFER_ALTERNATE_PLANE results in the image being
88 transferred to the alternate (e.g. overlay) plane. If your
89 hardware doesn't support such a plane, this is an error.
90 Specifing DIVE_BUFFER_SCREEN will result in the image being
91 transferred to either the graphics plane buffer or the alternate
92 plane buffer based on if an alternate buffer exists and based on
93 the suitability the overlay plane to accelerate the scaling of
94 the image. If DIVE chooses to use the alternate buffer, it
95 will also paint the overlay "key" color on the graphics plane.
96 This automatic painting does not occur if the alternate plane
97 is explicitly specified.

363/* Notes on palettes:
364 Neither DiveSetSourcePalette nor DiveSetDestinationPalette API's will set
365 the physical palette. If your application MUST set the PHYSICAL palette,
366 try using no more than 236 entries (the middle 236: 10-245, thus leaving
367 the top and bottom 10 entries for the Workplace Shell). If your
368 application MUST use ALL 256 entries, it must do so as a full-screen
369 (i.e. maximized) application. Remember, No WM_REALIZEPALETTE message
370 will be sent to other running applications, meaning they will not redraw
371 and their colors will be all wrong. It is not recommended that a
372 developer use these commands:
373
374 To set physical palette, do the following:
375 hps = WinGetPS ( HWND_DESKTOP );
376 hdc = GpiQueryDevice ( hps );
377 GpiCreateLogColorTable ( hps, LCOL_PURECOLOR | LCOL_REALIZABLE,

380 WinInvalidateRect ( HWND_DESKTOP, (PRECTL)NULL, TRUE );

382
383 To reset physical palette, do the following:

469/* Notes on transparent blitting:
470 Supported transparent blitting functions are all based on source pixel
471 values. A pixel in the destination image buffer is not modified if the
472 corresponding pixel in the source buffer is "transparent". The color
473 values or color value ranges specified in ulValue1 and ulValue2 are
474 dependent on the source image color format (fccSrcColorFormat) and the
475 color space in which the range comparison is taking place.
476
477 FOURCC_LUT8:
478 The color value is specified in the low 8 bits of parameter
479
480 FOURCC_Y888, FOURCC_Y2X2, FOURCC_Y4X4, FOURCC_YUV9, FOURCC_Y644, FOURCC_Y422:
481 23:8 - Y, 15:8 - U, 7:8 - V (bits 31:8 ignored)
482
483 FOURCC_R565, FOURCC_R555, FOURCC_R664, FOURCC_RGB3, FOURCC_BGR3, FOURCC_RGB4,
484 FOURCC_BGR4:
485 23:8 - R, 15:8 - G, 7:8 - B (bits 31:8 ignored)
486 R, G, and B components are specified with 8 bit significance, regardless
487 of significance in the source data.
488
489 Transparent blitting of other source image formats is not supported.
490
491 For range comparisons in RGB or YUV, the three components are compared
492 independently against the minimum and maximum values specified by the
493 ulValue1 and ulValue2 parameters respectively. A value is considered to
494 within the specified range if all three components satisfy:
495 min <= value <= max.
496
497 For EXCLUDE_SOURCE_VALUE tranparent blitting, the specified value in
498 ulValue1 is assumed to be in the source color space as described above.
499 For range comparisons, the values specified in ulValue1 and ulValue2 are
500 assumed to be in the color space in which the range comparison is to be
501 performed, either YUV or RGB.
502
503 - For range comparisons in YUV where the source data format is a YUV
504 form, the values in ulValue1 and ulValue2 are in the source YUV
505 format.
506
507 - For range comparisons in YUV where the source data format is RGB,
508 conversion of source data format from RGB to YUV using standard
509 CCIR601 equations is assumed (refer to fourcc.h).
510
511 - For range comparisons in RGB where the source data format is an RGB
512 form, the values in ulValue1 and ulValue2 specify the RGB range with
513 5 bits significance in R, 6 bits in G, and 5 bits in B.
514
515 - For range comparisons in RGB where the source data format is YUV,
516 conversion of source data format from YUV to RGB using standard
517 CCIR601 equations is assumed (refer to fourcc.h).

744 Ú¿ To convert from the four-bit chrominance
745 ÀÙ components to normal 8-bit, do:
746 U = 6.375 * ( U' - 5 )
747 V = 7.500 * ( V' - 6 )

760 two pixels. The left Y, the U and the V combine to
761 form the left CCIR601 color, and the right Y, the

763 effectively a 2x1 subsampling.

765 FOURCC_Y42B : Same as FOURCC_Y422, except byte swapped within words:

779 ³ ³ Use four consecutive 2-byte words as four pixels.
780 ³ ³ The is effectively a 4x1 subsampling. Each word

787 ÚÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ¿
788 Therefore, four pixels in a ³ Cr ³
789 row share a chrominace pair ÃÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄŽ
