This layer allows one to use any image as a map. You will need to tell it how to align the map to a position in the world and the scale of map.
+
+When a new image is selected the values from a World File will automatically be tried to be found.
+(subject to the setting in )
+
+
+
+&appname; does not currently support skew values and since World Files do not contain what coordinate system the coordinate values are in - &appname; assumes they are in UTM.
+
+
+
+If you do not know the scale of the map but know the coordinates of both upper left and lower right coordinates,
+ you can enter these coordinates (Lat/Lon only) and then use the Calculate MPP values from coordinates button.
+
+
+The map once loaded can be repositioned via , which may be easier than trying to edit the raw property values.

+
+Layer Properties
+
+Configurable properties:
+
+
+
+ The map image file.
+
+
+ X + Y Scales in metres per pixel.
+
+
+ Coordinates of the upper left corner of the map (either UTM or Lat/Lon value).
+
+
+ Alpha. Control the Alpha value for transparency effects using a value between 0 and 255 with the default being 255 for a fully solid image, whereas 0 is transparent.
