<br>
The mkgmap / display tool has a function to extract all the components<br>
from a gmapsupp.img and another function to take components and build a<br>
composite image.<br>
<br>
You'll need to get the sources from svn - see:<br>
<br>
<a href="https://www.mkgmap.org.uk/mkgmap/display" rel="noreferrer" target="_blank">https://www.mkgmap.org.uk/mkgmap/display</a><br>
<br>
and build it.<br>
<br>
In an empty directory, my unix command to extract is<br>
<br>
$ java -Xmx1540M -ea -classpath \<br>
/myMkgmap/display/trunk/build/classes:\<br>
/myMkgmap/svn/trunk/build/classes:\<br>
/myMkgmap/svn/trunk/lib/compile/fastutil-6.5.15-mkg.1b.jar:\<br>
/myMkgmap/svn/trunk/lib/compile/osmpbf-1.3.3.jar:\<br>
/myMkgmap/svn/trunk/lib/compile/protobuf-java-2.5.0.jar \<br>
test.ExtractFile ../gmapsupp.img<br>
<br>
Adjust paths as necessary to reference the display build and your<br>
standard mkgmap build.<br>
<br>
To reconstitute, adjust the contents of the folder to have the new TYP,<br>
then use the same command as above but replace the last line with, eg:<br>
test.ZipFile ../newgmap.img *<br>
<br>
This will probably change the order of the components and I've no idea<br>
if this matters, but, if it does, give an explicit list, derived from<br>
the output of ExtractFile, instead of *<br>
<br>
