<br>
I prepared a small set of codes to load compressed blob file from<br>
database and convert to png.<br>
<br>
It's on my github account here:<br>
<br>
<a href="https://github.com/cgilles/digikam-pgf-database" rel="noreferrer" target="_blank">https://github.com/cgilles/digikam-pgf-database</a><br>
<br>
To compile, you need Qt5 devel package (core and gui) and cmake :<br>
<br>
git clone <a href="https://github.com/cgilles/digikam-pgf-database.git" rel="noreferrer" target="_blank">https://github.com/cgilles/digikam-pgf-database.git</a><br>
cd digikam-pgf-database<br>
mkdir build<br>
cd build<br>
cmake ..<br>
make<br>
<br>
enjoy...<br>
