<h3 id="image">The image package</h3>
|

|

<p>
|

The <a href="/pkg/image/"><code>image</code></a> package has had a number of
|
||||
minor changes, rearrangements and renamings.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
Most of the color handling code has been moved into its own package,
|
||||
<a href="/pkg/image/color/"><code>image/color</code></a>.
|
||||
For the elements that moved, a symmetry arises; for instance,
|
||||
each pixel of an
|
||||
<a href="/pkg/image/#RGBA"><code>image.RGBA</code></a>
|
||||
is a
|
||||
<a href="/pkg/image/color/#RGBA"><code>color.RGBA</code></a>.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
The old <code>image/ycbcr</code> package has been folded, with some
|
||||
renamings, into the
|
||||
<a href="/pkg/image/"><code>image</code></a>
|
||||
and
|
||||
<a href="/pkg/image/color/"><code>image/color</code></a>
|
||||
packages.
|
||||
</p>
|
||||
|

<p>
|

The old <code>image.ColorImage</code> type is still in the <code>image</code>
|
||||
package but has been renamed
|
||||
<a href="/pkg/image/#Uniform"><code>image.Uniform</code></a>,
|
||||
while <code>image.Tiled</code>
|

has been renamed
