==Definition==
'''INT''' blendop_grayscale ( <'''INT''' blendopID> , <'''INT''' mode> )

Modify the [[blend table]] of the [[blend operation]] by modifying the colours, so the compononts of one colour is the same (this makes them appear gray). This means that the [[graphic]] the blend operation is assigned to will appear gray.

The source section of the [[blend table]] will be modified; this will clear the destination section of the blend table.

== Parameters ==
{|
| '''INT''' blendopID || - The [[blendopID]] of the [[blendop]] to modify.
|-
| '''FLOAT''' amount || - The mode to perform the grayscaling (see [[#Notes|notes]]).
|}

== Returns ==
'''INT''' : [[true]]
