<enum> <realm>Client</realm> <description> Used by <page>render.OverrideBlend</page> to determine how texture RGBA information should be interpreted when rendered. For more information refer to OpenGL's glBlendFunc page here: https://www.khronos.org/registry/OpenGL-Refpages/gl4/html/glBlendFunc.xhtml ⤶ <upload src="19952/8d96354db95acb4.png" size="573673" name="image.png" />⤶ ⤶ Clientside only.⤶ </description>⤶ These enums are used by <page>render.OverrideBlend</page> to determine what the Source and Destination color and alpha channel values for a given pixel will be multiplied by before they are sent to the <page text="Blend Function">enums/BLENDFUNC</page> to calculate the pixel's final color during draw operations. For an interactive demonstration of how these enums behave, see [Anders Riggelsen's Visual glBlendFunc Tool here](https://www.andersriggelsen.dk/glblendfunc.php) ⤶ </description>⤶ <items> <item key="BLEND_ZERO" value="0"></item>⤶ <item key="BLEND_ONE" value="1"></item>⤶ <item key="BLEND_DST_COLOR" value="2"></item>⤶ <item key="BLEND_ONE_MINUS_DST_COLOR" value="3"></item>⤶ <item key="BLEND_SRC_ALPHA" value="4"></item>⤶ <item key="BLEND_ONE_MINUS_SRC_ALPHA" value="5"></item>⤶ <item key="BLEND_DST_ALPHA" value="6"></item>⤶ <item key="BLEND_ONE_MINUS_DST_ALPHA" value="7"></item>⤶ <item key="BLEND_SRC_ALPHA_SATURATE" value="8"></item>⤶ <item key="BLEND_SRC_COLOR" value="9"></item>⤶ <item key="BLEND_ONE_MINUS_SRC_COLOR" value="10"></item>⤶ <item key="BLEND_ZERO" value="0">⤶ The Multiplier will be `r=0`, `g=0`, `b=0`, `a=0`⤶ ⤶ This is useful for removing the Source or Destination from the final pixel color.⤶ </item>⤶ <item key="BLEND_ONE" value="1">⤶ The Multiplier will be `r=1`, `g=1`, `b=1`, `a=1`⤶ ⤶ This is useful for keeping the Source or Destination as their starting values.⤶ </item>⤶ <item key="BLEND_DST_COLOR" value="2">⤶ The Multiplier will be the same as the Destination color and alpha.⤶ </item>⤶ <item key="BLEND_ONE_MINUS_DST_COLOR" value="3">⤶ Each color and alpha channel value of the Destination is subtracted from `1`.⤶ ⤶ **For Example:** ⤶ If your Destination channels are: `r=1`, `g=0.25`, `b=0.1`, `a=1` ⤶ They will be modified by: `r=1-1`, `g=1-0.25`, `b=1-0.1`, `a=1-1` ⤶ The final Multiplier value will be: `r=0`, `g=0.75`, `b=0.9`, `a=0`⤶ </item>⤶ <item key="BLEND_SRC_ALPHA" value="4">⤶ All color and alpha channels will be the same as the Source alpha value. ⤶ ⤶ **For Example:** ⤶ If your Source channels are: `r=0.1`, `g=0`, `b=1`, `a=0.5` ⤶ The final Multiplier value will be: `r=0.5`, `g=0.5`, `b=0.5`, `a=0.5`⤶ </item>⤶ <item key="BLEND_ONE_MINUS_SRC_ALPHA" value="5">⤶ All color and alpha channels will be set to the Source alpha value subtracted from `1`.⤶ ⤶ **For Example:** ⤶ If your Source channels are: `r=0`, `g=0.23`, `b=1`, `a=0.6` ⤶ The alpha channel will be modified by `a=1-0.6` ⤶ The final Multiplier value will be: `r=0.4`, `g=0.4`, `b=0.4`, `a=0.4`⤶ </item>⤶ <item key="BLEND_DST_ALPHA" value="6">⤶ All color and alpha channels will be set to the the Destination alpha value.⤶ ⤶ **For Example:** ⤶ If your Destination channels are: `r=0.1`, `g=0`, `b=1`, `a=0.5` ⤶ The final Multiplier value will be: `r=0.5`, `g=0.5`, `b=0.5`, `a=0.5`⤶ </item>⤶ <item key="BLEND_ONE_MINUS_DST_ALPHA" value="7">⤶ All color and alpha channels will be set to the Destination alpha value subtracted from `1`.⤶ ⤶ **For Example:** ⤶ If your Destination channels are: `r=0`, `g=0.23`, `b=1`, `a=0.6` ⤶ The alpha channel will be modified by `a=1-0.6` ⤶ The final Multiplier value will be: `r=0.4`, `g=0.4`, `b=0.4`, `a=0.4`⤶ </item>⤶ <item key="BLEND_SRC_ALPHA_SATURATE" value="8">⤶ </item>⤶ <item key="BLEND_SRC_COLOR" value="9">⤶ The Multiplier will be the same as the Source color and alpha.⤶ </item>⤶ <item key="BLEND_ONE_MINUS_SRC_COLOR" value="10">⤶ Each color and alpha channel value of the Source is subtracted from `1`.⤶ ⤶ **For Example:** ⤶ If your Source channels are: `r=1`, `g=0.25`, `b=0.1`, `a=1` ⤶ They will be modified by: `r=1-1`, `g=1-0.25`, `b=1-0.1`, `a=1-1` ⤶ The final Multiplier value will be: `r=0`, `g=0.75`, `b=0.9`, `a=0`⤶ </item>⤶ </items> </enum>
