When we resize image with both h and w there are transparent bands created

[whizzzkid]

when ever the image is resized with a new height and width. the scrip creates and image of the new height and width, but the actual image is smaller than the allocated leaving bands on sides and top/bottoms

when height>width then bands are created on left and right
when width>height bands are created on top and bottom

Solution in my next commit.
