[mkgmap-dev] Echange .typ-file in gmapsupp.img on Mac OS x 11 or newer?From Gerd Petermann gpetermann_muenchen at hotmail.com on Sat Jul 24 07:40:06 BST 2021
Hi Felix, The speed probably mostly depends on the disk speed (ssd or not). I see less than 10 secs for an extract from ssd to ssd, same for the rewrite for a 969 MB gmapsupp. BTW: It's much easier to use the jar files, memory doesn't seem to matter: java -cp d:\mkgmap\dist\mkgmap.jar;d:\display\dist\display.jar test.ExtractFile c:\temp\gmapsupp.img I think on unix-liked systems you need separator ":" instead of ";" between the two jars: java -cp d:\mkgmap\dist\mkgmap.jar:d:\display\dist\display.jar test.ExtractFile c:\temp\gmapsupp.img @Ticker: I would not mind to add the two methods to the mkgmap uk.me.parabola.util package and extract FileCopier also to that package Gerd ________________________________________ Von: mkgmap-dev <mkgmap-dev-bounces at lists.mkgmap.org.uk> im Auftrag von Felix Hartmann <extremecarver at gmail.com> Gesendet: Freitag, 23.

The components are not altered/rebuilt.
