Interestingly, I can't recreate the problem when the source image comes from a "colorwheel".
I've added a convert and extend node so when querying the node information, all the properties match the colorwheel node;
eg range, frame rate, extend, planes (C{rgb} 16 bit float, A 16 bit float)

This suggests there's something in the input image that's breaking the cornerpin node.
The source image is a jpg, loaded in with a file node with all settings default.

Also, the documentation mentions a mask input. My cop2 cornerpin node doesn't have a mask input or any mask parameters.

Hi there,
I'm trying to do a simple cornerpin setup, but it appears to be ignoring the alpha of the source.
I have an image with alpha=0.
I add a ChannelCopy node, set the target to "new plane" and set that to A, and set the source to 1.
My image now has solid alpha.
I then add a cornerpin node. Move the handles, then check the alpha. The alpha is black.
The corner_pin "plane scope" is set to *.
Is this a bug?
Thanks in advance for any help.
