The original size of the image was 7.9 x 1.98 cms. I
am trying to display the image with 2.91 x 0.71 cms.
But this seems not working. I am getting original size
on my document. Any suggestions please..

You should have said which FO processor you are using, you might
have hit an unimplemented feature.

Further (but unrelated) problems:
- The src should be an URL. You supplied a windows file name. You
 are lucky that your FO processor doesn't complain, but it's still
 not portable.
- The fo:external-graphic is defined as an empty element. You have
 put whitespace into it. That's illegal.
