== Description ==
This style displays the value of [osmwiki:Key:layer] as a colored underlay. This helps to check, if the correct `layer` value is tagged without the need to select every single way and look at the `layer` value. The following values are allowed: -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. All other values are reported as wrong value. There is a [wikitr:/Help/Dialog/MapPaint/StyleSettings style setting] to disallow also `layer=0`. The layers -9 to -4 and 4 to 9 each use the same color because `layer` values above 4 and below -4 are very rare (and often even errors). See also the legend below. You can change the colors in the [wikitr:/Help/Preferences/ColorPreference Colors preferences] of JOSM (also for -9 to -4 and 4 to 9 which use the same color by default). You should use Layer checker together with the default JOSM internal mappaint style. In the List of mappaint styles in the preferences Layer checker need to be below the internal style (which means higher priority).

For ideas/questions/bugs/suggestions or similar please write a message to [osmwww:user/Klumbumbus Klumbumbus]. Feel free to translate this wiki page into more languages. Already translated languages see top right.
