 <p>Packs <em class="parameter"><code>width</code></em>
  pixels from <em class="parameter"><code>src</code></em>
  to the given planes and strides in the
 format <em class="parameter"><code>info</code></em>
 . The pixels from source have each component interleaved
 and will be packed into the planes in <em class="parameter"><code>data</code></em>
 .</p>
 <p>This function operates on pack_lines lines, meaning that <em class="parameter"><code>src</code></em>
  should
 contain at least pack_lines lines with a stride of <em class="parameter"><code>sstride</code></em>
  and <em class="parameter"><code>y</code></em>

 should be a multiple of pack_lines.</p>
 <p>Subsampled formats will use the horizontally and vertically cosited
 component from the source. Subsampling should be performed before
 packing.</p>
 <p>Because this function does not have a x coordinate, it is not possible to
 pack pixels starting from an unaligned position. For tiled images this
 means that packing should start from a tile coordinate. For subsampled
 formats this means that a complete pixel needs to be packed.</p>

 <p>pixel stride for the given component. This is the amount of bytes to the
 pixel immediately to the right, so basically bytes from one pixel to the
 next. When bits &lt; 8, the stride is expressed in bits.</p>
 <p>Examples: for 24-bit RGB, the pixel stride would be 3 bytes, while it
 would be 4 bytes for RGBx or ARGB, and 8 bytes for ARGB64 or AYUV64.
 For planar formats such as I420 the pixel stride is usually 1. For
 YUY2 it would be 2 bytes.</p>
