[mkgmap-dev] Find Address - No cities

From Gerd Petermann GPetermann_muenchen at hotmail.com on Thu Aug 3 09:38:19 BST 2017

Hi  Ticker,

thanks. Please review:
You introduced new methods put1 and put2 in Interface ImgFileWriter and SectionWriter implements them but I don't find where they are used.

Gerd

Hi Gerd

Sorry - I did do "ant test", but this doesn't detect the missing
methods unless attempt made to call then.

New patch attached - I noticed that some of the new method comments
where not quite correct so I've improved these.

Regards
Ticker
