I suspect I need to use a function that is going to create a font matrix that is to my liking.. umm.. I probably need to get the existing font matrix some how.. first I use the function right below to get the matrix.. so I already created my personal variable "fatrix" 18 cairo_matrix_t * fatrix; That's in the file I originally attached.. so now I am going to use the get and set functions.. but in between, don't I have to rescale my matrix some how? so This function <a href="http://cairographics.org/manual/cairo-matrix.html#cairo-matrix-t">http://cairographics.org/manual/cairo-matrix.html#cairo-matrix-t</a> <h3>cairo_matrix_init_scale ()</h3> <pre class="programlisting">void cairo_matrix_init_scale (<a class="link" href="http://cairographics.org/manual/cairo-matrix.html#cairo-matrix-t" title="cairo_matrix_t">cairo_matrix_t</a> *matrix, double sx, double sy);</pre> Initializes <code>matrix</code> to a transformation that scales by <code>sx</code> and <code>sy</code> in the X and Y dimensions, respectively. <div class="variablelist"><table border="0"> <col align="left" valign="top"> <tbody> <tr> <td><code>matrix</code> :</td> <td> a <a class="link" href="http://cairographics.org/manual/cairo-matrix.html#cairo-matrix-t" title="cairo_matrix_t">cairo_matrix_t</a> </td> </tr> <tr> <td><code>sx</code> :</td> <td> scale factor in the X direction </td> </tr> <tr> <td><code>sy</code> :</td> <td> scale factor in the Y direction in betweem get and set? </td></tr></tbody></table></div> </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> behdad <div class="im"> > On Tue, Jul 27, 2010 at 11:50 PM, Kayven Riese <<a href="mailto:kayvey@gmail.com">kayvey@gmail.com</a> </div><div class="im">> <mailto:<a href="mailto:kayvey@gmail.com">kayvey@gmail.com</a>>> wrote: > > but that takes only cr as an argument.. so it is going to scale my > entire canvas right?
