This is wv2qt-0.4.2, initial source see: http://wvware.sourceforge.net/
We slightly modified the code to meet our need.

To build libs ... take qt5 & cd to wv2qt path
Edit the iconv lib path (only this need) or build self:

wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.13.1.tar.gz
gzip -dc < libiconv-1.13.1.tar.gz | tar -xf -
ls
cd libiconv-1.13.1
./configure --prefix=/opt/icon
make
sudo make install

after this lib...
qmake && make
at end
sudo make install
on error handle this..

this static or shared lib only need iconv.. this is deal... qt having all to handle image
on Window .... hmm google search word QAxWidget from qt or try to build this and handle error...
Ready to use on project:
Tested on Mac && linux
LIBS += -lz
LIBS += -L/opt/icon/lib -liconv -I/opt/icon/include
LIBS += -L/opt/icon/lib -lwv2qt -I/opt/icon/include

Dear reader this word lib is the result of hard, hard, hard work from many
week .... ok? Be Careful With My Heart... :-)
