This is 3000x600 pixels; what was the original size? (150x30?)

What does the original look like?

You need to test step by step to see at what point it goes wrong. You're scaling by 20 (which is a massive amount); what happens when scaling by 1? And anti-alias is turned off? (Which might let you see by how many pixels each successive line is out and could give a clue.)

It does seem as though something is going amiss with recognising the image dimensions, or you've inadvertently applied a 'shear' or 'slant' transformation. (Maybe you can apply a reverse transform to fix it!)
