The following article was posted to a newsgroup (possibly this one) a
few weeks ago.
My guess is that the code is in Fortran rather than C.  I am not sure
this will
solve your problem (viz. synthesis), but maybe it will help.

Preprints and software are available by anonymous ftp from the
Yale Mathematics Department computer ceres.math.yale.edu[130.132.23.22],
in pub/wavelets and pub/software.

epic is pyramid wavelet coder. (For source code, see question 3 in part one).

Bill Press of Harvard/CfA has made some things available for anonymous
ftp on site is 128.103.40.79, directory /pub. There is a short TeX
article on wavelet theory (wavelet.tex, to be included in a future
edition of Numerical Recipes), some sample wavelet code (wavelet.f, in
FORTRAN - sigh), and a beta version of an astronomical image
compression program which he is currently developing (FITS format data
files only, in fitspress08.tar.Z).
