Depends what you want to do. 
Reduce the pasted-in-layer to fit the small canvas. Use one of the scale tools on the pasted in layer 
or
Resize the canvas to fit the pasted in layer. Use Image -> Fit canvas to layers or if you want the 218 x 99 aspect ratio use 'Image -> Canvas size` and set the new size to 2255 x 1024 and resize layers to All layers

Just a question. Why 32 bit linear for a tiny image?

Thanks for helping!

Sorry I'm just a beginner
