Using Locus Pro 2.20.2 on Android Gingerbread.
Have got a JPEG, imported it into Map Calibrate section and set up 4 points which are all green and all within tolerance.
I have made the calibrated map and it appears in my Data screen under 'Items'. I select it or import it and nothing happens. The overlay of my JPEG doesnt appear on my map.
I have carefully followed the instructions on: http://docs.locusmap.eu/doku.php?id=manual:functions:on_board_map_calibrator
but if you look at the very last picture on that webpage... it shows the calibrated map sitting perfectly overlaid ontop of the regular map.... mine just doesnt appear and I've tried this over and over.edit
I made the calibrated map for a 5th time but this DIDN'T use the3 optimize map which it says in the app is 'highly recommended'.
It seems to have worked this time although the street names on the calibrated JPEG are completely unreadable as it seems to have knocked the image quality really down as the original image is big enough.
I have attached the original image for an opinion on it but as I say - every street name is just mush when used in Locus Pro.
Would be handy to know if the lack of using 'optimize map' is a bug or not?
Okay. I have just managed to figure it out myself and so hope my 3 posts on my thread help someone else.
The key to it is very important.... don't use any spaces when saving the calibrated map file name!
The optimize tickbox works well. If you leave it ticked you will end up with a calibrated map of the same quality you imported as your JPEG. But if you untick it, you will end up with a very low quality calibrated map in which certain aspects cannot be read.
So, all in all I've finally figured out this amazing feature. Keep the optimized box ticked, ensure you have 4 green calibrated points and most of all do not use any spaces when saving your file name,
Hope that helps someone else. Locus continues to amaze me.
