Rotate PNG by ImageMagick

I want to rotate PNG file by convert command. like this.

convert -background 'rgba(0,0,0,0.5)' -rotate 45 1.png r1.png

But result PNG file is wrong like following. https://docs.google.com/spreadsheet/ccc?key=0AqzGWe_mT6dwdEIwa04xRldwVGtOX1VGbVJhRnZwX0E

The gray space is correct.

I don't know why black space exists.

What am I wrong?

thank you.

The image to modify comes straight after convert.

Try:

convert 1.png -background "rgba(0,0,0,0.5)" -rotate 45 r1.png
