What happened

I was trying to transfer styles from an image to Icons, First issue I noticed is that black images can not be used as control layers, The Models totally ignore black images. So for instance i wanted to use a control layer to generate the structure of an Icon on the default transparent background (No Raster Layer). I added a totally black icon outline, Clicked "Invoke", it just made a random image and didnt follow the composition. To test, I opened up the image in Photoshop and inverted the colours, dropped the White icon outline into the control layer and clicked "Invoke" it then followed the compostion exactly.

Another problem I detected was that images smaller than 600px will not work as reference images for Flux.2

Maybe not a problem with Invoke, they might be a Model specific issue for Flux.2 or a Control Adapter issue, but seemed to be the same with both SDXL and Flux 1 Control Adapters.

Just thought i would mention it incase someone else thinks they are going mad aswell

What you expected to happen

Totally black images to be used correctly by the Control Adapter. Flux2 to be able to use references smaller than 600px, such as 512pxx512px icons.
