- <p>OCD is a set of Open Color format Definitions.</p>
-<p>Color formats are used in everything from BLTers to video codecs, and from cameras to displays. But although

- <p>OCD attempts to solve this problem. It provides logical color format codes, and

-<p class="Header1">Header File</p>
-<p><span class="filename">ocd.h</span> contains the Open Color format Definitions.</p>
-<p class="Header1">How does it work?</p>
-<p>OCD was designed to allow a single 32-bit word (int) to specify the
-color format. The color format is specified as an enumeration. The
-enumeration values are constructed using bitfields.</p>
-<p>OCD breaks off a chunk of those 32 bits to specify a vendor ID. With
-this, OCD can allow vendors with very unique formats to obtain their own vendor
-ID and specify any of 16 million formats of their own. Minimum sharing
-here, but maximum flexibility.</p>
-<p class="Code_Header_2">OCDFMTDEF_VENDOR_ALL</p>
-<p>The power of OCD lies in the shared vendor ID. The
-<span class="inline_code">OCDFMTDEF_VENDOR_ALL</span> vendor ID indicates that the common set of definitions is
-being used. And this set of definitions is designed to specify pretty much
-any reasonably common color format in use today.</p>
-<p>When <span class="inline_code">OCDFMTDEF_VENDOR_ALL</span> is chosen, the remaining 24 bits of the format are
-sub-divided into bitfields used to describe the format.</p>
-<p class="Header2">Predefined Names</p>
-<p>A set of enumeration values are already provided with predefined names.
-It is easiest for clients to use these predefined values. They already cover most of
-the formats likely to be encountered.</p>
-<p class="note">NOTE: The naming conventions of the predefined formats are based on their byte
-ordering, so they are not endian-dependent. The exceptions are the 16-bit
-packed formats, which are little-endian.</p>
-<p>Some examples:</p>
-<p class="indent"><span class="inline_code">OCDFMT_RGB24</span> is a format
-where each pixel consists of 3 bytes (24 bits). The first byte in memory
-(at address A, read as a byte) is the red component. The second byte in
-memory (at address A+1, read as a byte) is the green component. The third
-byte in memory (at address A+2, read as a byte) is the blue component.</p>
-<p class="indent">OCDFMT_xRGB24 is a format where each pixel consists of 4 bytes
-(32 bits), but only 3 of these (24 bits) contain color information. The
-remaining 8 bits are ignored on a read, or filled with 0s on a write.</p>
-<p>If the format of interest is not already specified, it is still likely that
-the format is supported by the VENDOR_ALL design. Using the bitfields below, new combinations can be constructed. These
-combinations are already legal, but they just have not been given names.
-Users of OCD can define their own names in a separate header file and include it
-using the OCD_EXTERNAL_INCLUDE mechanism:</p>
-<p class="indent">file: <span class="filename">myocdfmts.h</span></p>
-<p class="style5">MYOCDFMT_ALPHAMONO8 = OCDFMT_MONO8 |<br />
-
-OCDFMTDEF_ALPHA,</p>
-<p class="indent">file: <span class="filename">mysource.c</span></p>
-<p class="style5">#define OCD_EXTERNAL_INCLUDE "myocdfmts.h"<br />
-#include <ocd.h></p>
-<p class="Header2">VENDOR_ALL Bitfields</p>
-<p>The following bitfields only apply to the <span class="inline_code">
-OCDFMTDEF_VENDOR_ALL</span> color formats. </p>
-<p class="Header3">Color Space</p>
-<p>The first field specifies the color space. Currently there are five
-color spaces defined, but there is room for three more if the need arises:</p>
-<ul>
- <li>Monochrome - <span class="inline_code">OCDFMTDEF_CS_MONO</span></li>
- <li>Look-Up Table - <span class="inline_code">OCDFMTDEF_CS_LUT</span></li>
- <li>RGB -<span class="inline_code"> OCDFMTDEF_CS_RGB</span></li>
- <li>YCbCr (a.k.a. YUV) - <span class="inline_code">
- OCDFMTDEF_CS_YCbCr</span></li>
- <li>Alpha - <span class="inline_code">OCDFMTDEF_CS_ALPHA</span></li>
-</ul>
-<p>Once the color space has been selected, the remaining bits depend on that
-choice:</p>
-<p class="Code_Header_3">OCDFMTDEF_CS_MONO</p>

-<p class="Header3">Standard (YCbCr)</p>
-<p>This field specifies the standard being used for this color space.</p>
-<p>Currently, this field is only defined for the YCbCr color space:</p>
-<ul>
- <li><a href="http://www.itu.int/rec/R-REC-BT.601/en">ITU-R BT.601</a> - <span class="inline_code">
- OCDFMTDEF_STD_ITUR_601_YCbCr</span></li>
- <li><a href="http://www.itu.int/rec/R-REC-BT.709/en">ITU-R BT.709</a> - <span class="inline_code">
- OCDFMTDEF_STD_ITUR_709_YCbCr</span></li>
- <li><a href="http://www.w3.org/Graphics/JPEG/jfif3.pdf">Full Scale</a> - <span class="inline_code">
- OCDFMTDEF_FULLSCALE_YCbCr</span></li>
-</ul>
-<p>We believe that this field will be used to add linear format support in the
-very near future.</p>
-<p class="Header3">Fill Empty 0 (Mono, RGB, YCbCr)</p>
-<p>When there is no alpha included with a format, but the color components don't
-fill up the container, the remainder of the bits must be filled with something
-when written. When the <span class="inline_code">OCDFMTDEF_FILL_EMPTY_0</span>
-flag is not set, they are filled with 1. This is done in case they are
-later used as an alpha value, which will already represent an opaque pixel
-(whether the pixel is premultiplied or not). When the flag is set, they are
-filled with 0, to accommodate those environments where they are required to be
-cleared when unused.</p>
-<p class="Header3">Alpha (Mono, RGB, YCbCr)</p>
-<p>The <span class="inline_code">OCDFMTDEF_ALPHA</span> bit indicates that the
-format includes an alpha channel along with the main color components.</p>
-<p class="Header3">Non-Premult (Mono, RGB, YCbCr)</p>
-<p>Formats with alpha can have their color components pre-multiplied by the
-alpha component or not. When the <span class="inline_code">
-OCDFMTDEF_NON_PREMULT</span> bit is set, the color components are not
-premultiplied by the accompanying alpha. When the bit is not set, the
-color components are already multiplied by the alpha.</p>
-<p class="Header3">Subsampling (YCbCr)</p>
-<p>Some formats can be subsampled. At this point, only subsampled YCbCr is
-supported.</p>
-<ul>
- <li>No subsampling - <span class="inline_code">
- OCDFMTDEF_SUBSAMPLE_NONE</span></li>
- <li>4:2:2 subsampling - <span class="inline_code">
- OCDFMTDEF_SUBSAMPLE_422_YCbCr</span></li>
- <li>4:2:0 subsampling - <span class="inline_code">
- OCDFMTDEF_SUBSAMPLE_420_YCbCr</span></li>
- <li>4:1:1 subsampling - <span class="inline_code">
- OCDFMTDEF_SUBSAMPLE_411_YCbCr</span></li>
-</ul>
-<p class="Header3">Subsample Position (YCbCr)</p>
-<p>Subsampling can have different equivalent positions relative to the pixels.
-Vertical subsampling positions are consistent, so the following are supported to
-control the horizontal subsampling position:</p>
-<ul>
- <li><span class="inline_code">OCDFMTDEF_SUBSAMPLE_HORZ_ALIGNED </span>- subsamples are aligned with first pixel (e.g. MPEG-2
- spec)</li>
- <li><span class="inline_code">OCDFMTDEF_SUBSAMPLE_HORZ_CENTERED
- </span>- subsamples are centered between the pixels (e.g. MPEG-1
- spec)</li>
-</ul>
-<p>NOTE: It is encouraged that users of OCD be generous when handling
-subsampling positions. Allowing misaligned subsampling is preferable to
-complete failure.</p>
-<p class="Header3">Alpha Components (Alpha)</p>
-<p>To support applying alpha values to the individual components of other color
-spaces, the alpha color space can have more than one alpha value per pixel.
-This field specifies how many:</p>
-<ul>
- <li><span class="inline_code">OCDFMTDEF_ALPHA_COMPONENTS_1 </span>- pixel contains 1 alpha value (default)</li>
- <li><span class="inline_code">OCDFMTDEF_ALPHA_COMPONENTS_2
- </span>- pixel contains 2 alpha values</li>
- <li><span class="inline_code">OCDFMTDEF_ALPHA_COMPONENTS_3
- </span>- pixel contains 3 alpha values; suitable for RGB
- manipulation (e.g. FreeType/ClearType)</li>
- <li><span class="inline_code">OCDFMTDEF_ALPHA_COMPONENTS_4
- </span>-- pixel contains 4 alpha values</li>
-</ul>
-<p class="Header3">Layout (RGB, YCbCr)</p>
-<p>The layout values, in conjunction with the reversed and left-justified
-modifiers, specify how the pixel components are placed into memory. All
-non-RGB/YCbCr formats are packed.</p>
-<ul>
- <li><span class="inline_code">OCDFMTDEF_PACKED </span>- pixel
- components are sequential in memory, defaulting to RGB or CbCr
- order, right justified</li>
- <li><span class="inline_code">OCDFMTDEF_DISTRIBUTED </span>-
- pixel components that don't fill the container are evenly
- distributed within the container (e.g. 32 bits of ARGB in a
- 64-bit container is distributed 8 bits every 16 bits: xAxRxGxB)</li>
- <li><span class="inline_code">OCDFMTDEF_2_PLANE_YCbCr </span>-
- for subsampled formats only, Y plane is followed by subsampled
- interleaved CbCr plane</li>
- <li><span class="inline_code">OCDFMTDEF_3_PLANE_STACKED </span>-
- pixel components are divided into planes that are sequential in
- memory</li>
- <li><span class="inline_code">
- OCDFMTDEF_3_PLANE_SIDE_BY_SIDE_YCbCr </span>- for subsampled
- formats only pixel components are divided into planes, with the
- non-subsampled component followed by the subsampled components
- stored side-by-side (lines interleaved) </li>
-</ul>
-<p class="Header3">Reversed (RGB, YCbCr)</p>
-<p><span class="inline_code">OCDFMTDEF_REVERSED</span> indicates that the order
-of the color components is the opposite of the defaults. For RGB formats,
-this means BGR. For YCbCr formats, this means CrCb.</p>
-<p class="Header3">Left-Justified (RGB, YCbCr)</p>
-<p><span class="inline_code">OCDFMTDEF_LEFT_JUSTIFIED</span> indicates that the
-color components are shifted to the left, as opposed to the default of shifting
-to the right.</p>
-<p>Some examples for <span class="inline_code">OCDFMTDEF_REVERSED</span> and
-<span class="inline_code">OCDFMTDEF_LEFT_JUSTIFIED</span>:</p>
-<ul>
- <li>Packed RGB: x,R,G,B is the default byte order<ul>
- <li>x,B,G,R is the format if
- <span class="inline_code">OCDFMTDEF_REVERSED</span>
- is set</li>
- <li>R,G,B,x is the format if
- <span class="inline_code">
- OCDFMTDEF_LEFT_JUSTIFIED</span> is set</li>
- <li>B,G,R,x is the format if
- <span class="inline_code">OCDFMTDEF_REVERSED</span>
- and <span class="inline_code">
- OCDFMTDEF_LEFT_JUSTIFIED</span> are set</li>
- </ul>
- </li>
- <li>Packed YCbCr 4:2:2: U,Y,V,Y is the default byte order<ul>
- <li>V,Y,U,Y is the format if
- <span class="inline_code">OCDFMTDEF_REVERSED</span>
- is set</li>
- <li>Y,U,Y,V is the format if
- <span class="inline_code">
- OCDFMTDEF_LEFT_JUSTIFIED</span> is set</li>
- <li>Y,V,Y,U is the format if
- <span class="inline_code">OCDFMTDEF_REVERSED</span>
- and <span class="inline_code">
- OCDFMTDEF_LEFT_JUSTIFIED</span> are set</li>
- </ul>
- </li>
- <li>3-Plane YCbCr 4:2:2 or 4:2:0: The default is the Y
- plane, followed by the Cb plane and then the Cr plane. The
- Cb and Cr planes have half of the stride of the Y plane.<ul>
- <li>If <span class="inline_code">
- OCDFMTDEF_REVERSED</span> is set, the Cb and Cr
- planes are reversed.</li>
- <li><span class="inline_code">
- OCDFMTDEF_LEFT_JUSTIFIED</span> has a special
- case for this layout. When set, it
- indicates that the Cb and Cr planes have the
- same stride as the Y plane, and the Cb and Cr
- data is shifted to the left.</li>
- <li>If both <span class="inline_code">
- OCDFMTDEF_LEFT_REVERSED</span> and
- <span class="inline_code">
- OCDFMTDEF_LEFT_JUSTIFIED</span> are set, the Cb
- and Cr planes are reversed and double width.</li>
- </ul>
- </li>
- <li>2-Plane YCbCr 4:2:2 or 4:2:0: The default is the Y
- plane, followed by the CbCr interleaved plane, with the same
- stride as the Y plane.<ul>
- <li><span class="inline_code">OCDFMTDEF_REVERSED</span>
- swaps the Cb and Cr components.</li>
- </ul>
- </li>
-</ul>
-<p class="Header3">Container (All)</p>
-<p>The container field indicates the total size of all the bits of the color
-components of a color format. This does not include the alpha component,
-if it is present.</p>
-<ul>
- <li><span class="inline_code">OCDFMTDEF_CONTAINER_8BIT</span> -
- Indicates the container is 8 bits. When the pixel
- component size is 4 bits or less, multiple pixels are stored in
- the container.</li>
- <li><span class="inline_code">OCDFMTDEF_CONTAINER_16BIT</span> -
- Indicates the container is 16 bits. When the pixel
- component size is less than 16 bits, the remaining bits are
- available to be used as an alpha channel.</li>
- <li><span class="inline_code">OCDFMTDEF_CONTAINER_24BIT</span> -
- Indicates the container is 24 bits. When the pixel
- component size is less than 24 bits, the remaining bits are
- available to be used as an alpha channel.</li>
- <li><span class="inline_code">OCDFMTDEF_CONTAINER_32BIT</span> -
- Indicates the container is 32 bits. When the pixel
- component size is less than 32 bits, the remaining bits are
- available to be used as an alpha channel.</li>
- <li><span class="inline_code">OCDFMTDEF_CONTAINER_48BIT</span> -
- Indicates the container is 48 bits. When the pixel
- component size is less than 48 bits, the remaining bits are
- available to be used as an alpha channel.</li>
- <li><span class="inline_code">OCDFMTDEF_CONTAINER_64BIT</span> -
- Indicates the container is 64 bits. When the pixel
- component size is less than 64 bits, the remaining bits are
- available to be used as an alpha channel.</li>
-</ul>
-<p class="Header3">Component Size (All)</p>
-<p>The component size field specifies the total number of bits in the color
-components, not including the alpha component. (It is specified in the
-code with one subtracted.)</p>
-<p class="note">NOTE: The alpha only color space uses this to specify the total number
-of alpha bits.</p>
