Export or Save to a specific size PNG/JPEG

I need to export a Graffle for a logo for my wife. The logo needs to be 244 x 50 pixels in size (for a discourse forum). How do I export to a specific size?


A possible workaround. Perhaps you could “Copy As” a PDF the objects you wish to include in the logo, “Paste in Place”, and resize that to the desired size (with appropriate border spacings) prior to export?
