Hello,<br><br>i don&#39;t know if this is the right place to write, sorry if don&#39;t.<br><br>I&#39;m working in a project with PD/Gem and i need more blending methods than the original Alpha object has. I&#39;ve modified slightliy the file alpha.cpp (see atachment) and recompiled Gem. Simply i&#39;ve add the different OpenGL blending mehods to the switch in the function funmess(). Some are working in mi system (Debian Wheezy), others are the same output than GL_ONE. I like specially GL_ONE_MINUS_SRC_COLOR, it doesn&#39;t saturate the bright pixels like GL_ONE_MINUS_SRC_ALPHA does.<br>
<br>My question: Is there any reason to not include different alpha blending methods? the modification i&#39;ve made is very simple and obvious, so i&#39;m thinking about why not had made before... do i have lost something?<br>
<br>Regards and sorry for my english...<br><br>Santi Noreņa     <br>
