Android based on Mappwidget implementation freehand Map (v)--How to create a map resource

Map resources can be generated from the slicing tool tools, as follows:

1. Open Eclipse Standard Version 4.3.2, import the "Slicingtool" project as a Java project, run. (Must be eclipse4.3.2 and above version, or will be less packet and error)

2. A new eclipse will be opened at this time, and in the new widow-->show View-->mappwidget-->map slicing Tool, open the window:

Select the size of the block (256 block for general recommendation)

If you want to use the GPS features of the map, fill in the correction data

After export, you will get an XML file and a lot of PNG files and copy them to the project's assets:

Manual calibration: To make it easy for you to calibrate your offline map manually, you can modify the Map.xml, similar to this:

<?xml version= "1.0" encoding= "Utf-8"? ><image format= "PNG" overlap= "1" tilesize= "" "><size height=" 970 "width=" 1665 ">  <calibrationrect>      <point lat=" 51.512234697322576 "lon="- 0.18319487571716309 "topleft=" 1 "x=" 218 "y=" ">      <point lat=" 51.50428161952125 "lon="- 0.15317827463150024 "x=" 1625 "y=" 728 ">  </calibrationrect></image>

The map resource is the following structure:

<map_name>_files files are stored in the Zoom level folder. In this picture 0 is the lowest zoom level, and 11 is the highest zoom level. The highest zoom level is the original picture that is cut into a broken-down grid. Any slice file is named in the following format: (< column name >_< row name >.png)

<map_name>.xml is a configuration file for offline maps.
