<p>The pitch's absolute value is the number of bytes taken by one bitmap row, including padding. However, the pitch is positive when the bitmap has a &lsquo;down&rsquo; flow, and negative when it has an &lsquo;up&rsquo; flow. In all cases, the pitch is an offset to add to a bitmap pointer in order to go down one row.</p>
<p>Note that &lsquo;padding&rsquo; means the alignment of a bitmap to a byte border, and FreeType functions normally align to the smallest possible integer value.</p>
<p>For the B/W rasterizer, &lsquo;pitch&rsquo; is always an even number.</p>
<p>To change the pitch of a bitmap (say, to make it a multiple of 4), use <a href="ft2-bitmap_handling.html#FT_Bitmap_Convert">FT_Bitmap_Convert</a>. Alternatively, you might use callback functions to directly render to the application's surface; see the file &lsquo;example2.cpp&rsquo; in the tutorial for a demonstration.</p>
