We have dozens of tests which deal with image scaling. May be you have 
found a case which is not covered by our tests. On the other hand, may 
be your issue is triggered by the context in which you use the 
fo:external-graphic.

Don't know.

Please provide us with an actual, valid, XSL-FO file (a .fo, not a .xsl) 
which would allow us to quickly and easily reproduce the problem here at 
XMLmind. If this XSL-FO file references external graphics files (e.g. 
PNG), please also send us these graphics files.
