Locus Map enables using custom icons for Points, points folders and also Tracks/routes folders (custom icons are not supported in Livetracking).

Once you create or download an icon pack you may simply select folder icons in Folder add/edit dialog or in Edit dialog for points (simply tap on point and choose edit from sub-menu)

• directory: usually Android/data/menion.android.locus/files/Locus/icons/ (check in the “About App” section of the main menu)
• pack: zipped (*.zip)

• create or download custom icons in .PNG format
• the size of icons is upon you but we recommend the size 96x96px. You can also set the size by adding the _sX.X parameter to the icon filename - the range is 0.5 to 10.0 times the default size. Example: icon_sX.X.png
• default align of all icons is center bottom line. If you want the icons to be aligned center-center, add _hscc (hot spot - center-center) to the end of the icon name. Example: icon_hscc.png
• both parameters can be combined. Size first, align second. Example: icon_sX.X_hscc.png
• pack the icons to a ZIP file and copy it into the Locus/icons directory. DO NOT compress a folder with icons - the icons must be in the root of the ZIP file.
• some icons are already available in the Locus Store. Do you want to place some of your own there? Get in touch with us!

If you need to have your custom icons sorted into groups here's the solution:

• edit and add the following XML file into the .ZIP pack with the icons. It defines commonly used “info” that Locus Map uses in many places for various files. Next to this main <item> tag with meta-information, there's a new container <content> that contains meta-information related to the content of the file itself. There are also a few comments so it should be clear:
  

info.xml

<?xml version="1.0" encoding="utf-8"?>
<items version="1">
 
	<!-- container with item meta information -->
	<item>

Important is tag <category> that defines your group of items.

One of the possible custom modifications in Locus Map is the option to set your own cursors (images) on the map. Here is a short explanation of how to do it:

All possibilities are divided into two packs – Basic cursors and Navigation cursors

• all subfolders in the ZIP file are optional. They may be used if you want to create some publicly available icons (we’ll gladly put them in Locus Store, possibly also as paid content). In this case, Locus Map selects automatically the best folder.
• if you want to use the pack just for your personal purposes, best is to put the icons at root of the .zip file

• directory: Locus/icons/cursors/
• pack: zipped (*.zip)
• where to select: Locus settings > Controlling > Map screen > Screen cursors

content: (example name ‘myIcons.zip’) - name the files according to this sample:

  myIcons.zip
    nodpi/ (optional)
      ic_location_gps.png
      ic_location_network.png
      ic_location_cross.png
      ic_location_move.png
      ic_location_view.png
      ic_rotate_arrow.png
    xhdpi/ (optional)
      ic_loc …
    hdpi/ (optional)
      ic_loc …
    mdpi/ (optional)
      ic_loc …
    ldpi/ (optional)
      ic_loc …
    ic_location_gps.png
    ic_loc…

• directory: Locus/icons/navigation/
• pack: zipped (*.zip)
• where to select: Locus settings > Navigation > Advanced settings > Navigation cursors

content: (example name ‘myIcons.zip’) - name the files according to this sample:

  myIcons.zip
      nodpi/ (optional)
          ic_navig_foot.png
          ic_navig_cycle.png
          ic_navig_car.png
      xhdpi/ (optional)
          ic_nav …
      hdpi/ (optional)
          ic_nav …
      mdpi/ (optional)
          ic_nav …
      ldpi/ (optional)
          ic_nav …
      ic_navig_foot.png
      ic_nav …

Locus Map offers also ability to create custom icons for geocaches. Current implementation isn't as straightforward as adding custom icons described above, anyway we suggest to read that also.

The whole procedure requires a few steps:

• creating an icon pack
• uploading it into Locus/icons directory
• configuring Locus Map to use these icons

Images of caches are usually created from one icon (in case of disabled and other statuses it's more than one). Anyway this new system offers to create icons with various parameters.

Firstly, prepare images you want to use. At the bottom of this page, there is a list of possible image names. I'll not explain all images, as all are self-explaining by their names.

You don't have to use all images. Locus Map will firstly try to load images from your pack and in case an icon is missing, the default will be used.

Compress all icons to a .zip file (icons will be stored directly in zip, not in any sub-directory) and place them into Locus/icons directory.

In order to use these icons as a substitution for default Locus Map icons you have to specify this file in Locus Configuration file. So edit this file and specify the zipped file into the parameter geocaching_icon_pack. That's all you need to do.
