I need your idea

[Simpson]

I think your imagery will completely fill output image if dimensions of
output image are adjusted to the same aspect ratio as your imagery.

x	521317 - 414562 = 106755
y	4617510- 4510820 = 106690

ratio y/x = 0.999391

So in pixels, if you prefer to leave your x at 400, then your y should be
400 * 0.999391 = 399.7565, round to 400.

Not sure what you mean by the 'The image is unzoomed'.  What result do you
get?

Drew.

    if Mapserver maintains aspect ratio, all my efforts will be useless.
    But with zoom tool I can achieve the zooming of satellite imagery.
    Besides, I tried (0,406,400,0) pixel extent. The image is unzoomed.
