<p><a class="reference internal" href="#c.TIFFDeferStrileArrayWriting" title="TIFFDeferStrileArrayWriting"><code class="xref c c-func docutils literal notranslate"><span class="pre">TIFFDeferStrileArrayWriting()</span></code></a> is an advanced writing function
that must be used in a particular sequence, and generally together
with <a class="reference internal" href="#c.TIFFForceStrileArrayWriting" title="TIFFForceStrileArrayWriting"><code class="xref c c-func docutils literal notranslate"><span class="pre">TIFFForceStrileArrayWriting()</span></code></a>, to achieve its intended
effect. Their aim is to control when and where the
<code class="docutils literal notranslate"><span class="pre">StripOffsets</span></code> / <code class="docutils literal notranslate"><span class="pre">StripByteCounts</span></code> or <code class="docutils literal notranslate"><span class="pre">TileOffsets</span></code> / <code class="docutils literal notranslate"><span class="pre">TileByteCounts</span></code>
arrays are written into the file.</p>
<p>The purpose of this is to generate ‘cloud-optimized geotiff’ files where
the first KB of the file only contain the IFD entries without the potentially
large strile arrays. Those are written afterwards.</p>
<p>More precisely, when <a class="reference internal" href="TIFFWriteDirectory.html#c.TIFFWriteCheck" title="TIFFWriteCheck"><code class="xref c c-func docutils literal notranslate"><span class="pre">TIFFWriteCheck()</span></code></a> is called, the tag entries for
those arrays will be written with type = count = offset = 0 as a temporary value.</p>
<p>Its effect is only valid for the current directory, and before
<a class="reference internal" href="TIFFWriteDirectory.html#c.TIFFWriteDirectory" title="TIFFWriteDirectory"><code class="xref c c-func docutils literal notranslate"><span class="pre">TIFFWriteDirectory()</span></code></a> is first called, and will be reset
when changing directory.</p>
<p>The typical sequence of calls is:</p>
<div class="highlight-c notranslate"><div class="highlight"><pre><span></span><span class="n">TIFFOpen</span><span class="p">()</span>
<span class="cm">/* or TIFFCreateDirectory(tif) */</span>
<span class="cm">/* Set fields with calls to TIFFSetField(tif, ...) */</span>
<span class="n">TIFFDeferStrileArrayWriting</span><span class="p">(</span><span class="n">tif</span><span class="p">)</span>
<span class="n">TIFFWriteCheck</span><span class="p">(</span><span class="n">tif</span><span class="p">,</span><span class="w"> </span><span class="p">...)</span>
<span class="n">TIFFWriteDirectory</span><span class="p">(</span><span class="n">tif</span><span class="p">)</span>
<span class="cm">/* ... potentially create other directories and come back to the above directory */</span>
<span class="n">TIFFForceStrileArrayWriting</span><span class="p">(</span><span class="n">tif</span><span class="p">)</span><span class="w"> </span><span class="cm">/* emit the arrays at the end of file */</span>
