</p></dd></dl></div></div><div class="refsect1"><a id="description"></a><h2>Description</h2><p>
Texturing maps a portion of a specified texture image
onto each graphical primitive for which texturing is enabled.
To enable and disable one-dimensional texturing, call <a class="citerefentry" href="glEnable.xml"><span class="citerefentry"><span class="refentrytitle">glEnable</span></span></a>
and <a class="citerefentry" href="glDisable.xml"><span class="citerefentry"><span class="refentrytitle">glDisable</span></span></a> with argument <code class="constant">GL_TEXTURE_1D</code>.
</p><p>
Texture images are defined with <code class="function">glTexImage1D</code>.
The arguments describe the parameters of the texture image,
such as width,
width of the border,
level-of-detail number
(see <a class="citerefentry" href="glTexParameter.xml"><span class="citerefentry"><span class="refentrytitle">glTexParameter</span></span></a>),
and the internal resolution and format used to store the image.
The last three arguments describe how the image is represented in
memory.
</p><p>
If <em class="parameter"><code>target</code></em> is <code class="constant">GL_PROXY_TEXTURE_1D</code>, no data is read from <em class="parameter"><code>data</code></em>, but
all of the texture image state is recalculated, checked for
consistency, and checked against the implementation's capabilities.
If the implementation cannot handle a texture of the
requested texture size, it sets all of the image state to 0,
but does not generate an error (see <a class="citerefentry" href="glGetError.xml"><span class="citerefentry"><span class="refentrytitle">glGetError</span></span></a>). To query for an
entire mipmap array, use an image array level greater than or equal to
1.
</p><p>
If <em class="parameter"><code>target</code></em> is <code class="constant">GL_TEXTURE_1D</code>,
data is read from <em class="parameter"><code>data</code></em> as a sequence of signed or unsigned bytes,
shorts,
or longs,
or single-precision floating-point values,
depending on <em class="parameter"><code>type</code></em>.
These values are grouped into sets of one,
two,
three,
or four values,
depending on <em class="parameter"><code>format</code></em>,
to form elements.
Each data byte is treated as eight 1-bit elements,
with bit ordering determined by <code class="constant">GL_UNPACK_LSB_FIRST</code>
(see <a class="citerefentry" href="glPixelStore.xml"><span class="citerefentry"><span class="refentrytitle">glPixelStore</span></span></a>).
</p><p>
If a non-zero named buffer object is bound to the <code class="constant">GL_PIXEL_UNPACK_BUFFER</code> target
(see <a class="citerefentry" href="glBindBuffer.xml"><span class="citerefentry"><span class="refentrytitle">glBindBuffer</span></span></a>) while a texture image is
specified, <em class="parameter"><code>data</code></em> is treated as a byte offset into the buffer object's data store.
</p><p>
The first element corresponds to the left end of the texture array.
Subsequent elements progress left-to-right through the remaining texels
in the texture array.
The final element corresponds to the right end of the texture array.
</p><p>
<em class="parameter"><code>format</code></em> determines the composition of each element in <em class="parameter"><code>data</code></em>.
It can assume one of these symbolic values:
</p><div class="variablelist"><dl class="variablelist"><dt><span class="term"><code class="constant">GL_RED</code></span></dt><dd><p>
Each element is a single red component.
The GL converts it to floating point and assembles it into an RGBA element
by attaching 0 for green and blue, and 1 for alpha.
Each component is clamped to the range [0,1].
</p></dd><dt><span class="term"><code class="constant">GL_RG</code></span></dt><dd><p>
Each element is a single red/green double
The GL converts it to floating point and assembles it into an RGBA element
by attaching 0 for blue, and 1 for alpha.
Each component is clamped to the range [0,1].
</p></dd><dt><span class="term"><code class="constant">GL_RGB</code>, </span><span class="term"><code class="constant">GL_BGR</code></span></dt><dd><p>
Each element is an RGB triple.
The GL converts it to floating point and assembles it into an RGBA element
by attaching 1 for alpha.
Each component is clamped to the range [0,1].
</p></dd><dt><span class="term"><code class="constant">GL_RGBA</code>, </span><span class="term"><code class="constant">GL_BGRA</code></span></dt><dd><p>
Each element contains all four components.
Each component clamped to the range [0,1].
</p></dd><dt><span class="term"><code class="constant">GL_DEPTH_COMPONENT</code></span></dt><dd><p>
Each element is a single depth value.
The GL converts it to floating point and clamps to the range [0,1].
</p></dd></dl></div><p>
If an application wants to store the texture at a certain
resolution or in a certain format, it can request the resolution
and format with <em class="parameter"><code>internalFormat</code></em>. The GL will choose an internal
representation that closely approximates that requested by <em class="parameter"><code>internalFormat</code></em>, but
it may not match exactly.
(The representations specified by <code class="constant">GL_RED</code>, <code class="constant">GL_RG</code>,
<code class="constant">GL_RGB</code> and <code class="constant">GL_RGBA</code> must match exactly.)

<code class="constant">GL_COMPRESSED_RED</code>, <code class="constant">GL_COMPRESSED_RG</code>,
<code class="constant">GL_COMPRESSED_RGB</code>, or
<code class="constant">GL_COMPRESSED_RGBA</code>, the GL will replace the internal format with the symbolic constant for a specific internal format and compress the texture before storage. If no corresponding internal format is available, or the GL can not compress that image for any reason, the internal format is instead replaced with a corresponding base internal format.

Use the <code class="constant">GL_PROXY_TEXTURE_1D</code> target to try out a resolution and
format. The implementation will
update and recompute its best match for the requested storage resolution
and format. To then query this state, call <a class="citerefentry" href="glGetTexLevelParameter.xml"><span class="citerefentry"><span class="refentrytitle">glGetTexLevelParameter</span></span></a>.
If the texture cannot be accommodated, texture state is set to 0.

A one-component texture image uses only the red component of the RGBA
color from <em class="parameter"><code>data</code></em>.
A two-component image uses the R and A values.
A three-component image uses the R, G, and B values.
A four-component image uses all of the RGBA components.
</p><p>
Image-based shadowing can be enabled by comparing texture r coordinates to depth texture values to generate a boolean result. See <a class="citerefentry" href="glTexParameter.xml"><span class="citerefentry"><span class="refentrytitle">glTexParameter</span></span></a> for details on texture comparison.

<em class="parameter"><code>data</code></em> may be a null pointer. In this case texture memory is
allocated to accommodate a texture of width <em class="parameter"><code>width</code></em>.
You can then download subtextures to initialize the
texture memory. The image is undefined if the program tries to apply
an uninitialized portion of the texture image to a primitive.
