<p>When creating a new face object (e.g., with <a href="ft2-base_interface.html#FT_New_Face">FT_New_Face</a>), an <a href="ft2-base_interface.html#FT_Size">FT_Size</a> object is automatically created and used to store all pixel-size dependent information, available in the ‘face->size’ field.</p>
<p>It is however possible to create more sizes for a given face, mostly in order to manage several character pixel sizes of the same font family and style. See <a href="ft2-sizes_management.html#FT_New_Size">FT_New_Size</a> and <a href="ft2-sizes_management.html#FT_Done_Size">FT_Done_Size</a>.</p>
<p>Note that <a href="ft2-base_interface.html#FT_Set_Pixel_Sizes">FT_Set_Pixel_Sizes</a> and <a href="ft2-base_interface.html#FT_Set_Char_Size">FT_Set_Char_Size</a> only modify the contents of the current ‘active’ size; you thus need to use <a href="ft2-sizes_management.html#FT_Activate_Size">FT_Activate_Size</a> to change it.</p>
<p>99% of applications won't need the functions provided here, especially if they use the caching sub-system, so be cautious when using these.</p>

I live in Matão, a small city in Brazil. I studied as Programmer in a College for Software Development in Database.
After finishing the College I have been working with java, c# and Computer Graphics with searches for OpenGL.
