<a name="details" id="details"></a><h2 class="groupheader">Detailed Description</h2>
<p>The GLC transformation commands modify the value of <b>GLC_BITMAP_MATRIX</b>. </p>
<p>Glyph coordinates are defined in the em coordinate system. When the value of <b>GLC_RENDER_STYLE</b> is <b>GLC_BITMAP</b>, GLC uses the 2x2 <b>GLC_BITMAP_MATRIX</b> to transform layouts from the em coordinate system to the GL raster coordinate system in which bitmaps are drawn.</p>
<p>When the value of the variable <b>GLC_RENDER_STYLE</b> is not <b>GLC_BITMAP</b>, GLC performs no transformations on glyph coordinates. In this case, GLC uses em coordinates directly as GL world coordinates when drawing a layout, and it is the responsibility of the GLC client to issue GL commands that set up the appropriate GL transformations.</p>
<p>There is a stack of matrices for <b>GLC_BITMAP_MATRIX</b>, the stack depth is at least 32 (that is, there is a stack of at least 32 matrices). Matrices can be pushed or popped in the stack with <a class="el" href="group__transform.html#ga4c4a11ea77e853c2196d5f62133a89db" title="This command pushes the stack down by one, duplicating the current GLC_BITMAP_MATRIX in both the top ...">glcPushMatrixQSO()</a> and <a class="el" href="group__transform.html#gacab52dd7062ee6fc45cac447b9ce48fa" title="This command pops the top entry off the stack, replacing the current GLC_BITMAP_MATRIX with the matri...">glcPopMatrixQSO()</a>.
