API Doc
Area
An area is described (when retrieved or set) by a json object:
{
x, // X coordinate (Position)
y, // Y coordinate (Position)
z, // Z-index (0 when inactive or 100 when focused)
width, // Width of the area (Size)
height // Height of the area (Size)
}
Options and parameters
Here is a list of available options for selectAreas, with their default value:
-
ng-areas : Required attribute. Area list areas ([]) : list of areas to add to the image from the beginning (id will be ignored);
controller i.e.:
$scope.areasArray = [ {
"x" : 557,
"y" : 35,
"z" : 100,
"height" : 130,
"width" : 925,
"name" : "Menu Options",
"cssClass" : "class_red",
"id" : 37,
"description" : "Menu"
}, {
"x" : 822,
"y" : 274,
"z" : 0,
"height" : 250,
"width" : 829,
"name" : "AngularJS Main Logo",
"cssClass" : "class_red",
"id" : 35,
"description" : "AngularJS Main Logo"
} ];
template i.e.:
<img ng-areas="areasArray" src="aImage.jpg">
-
ng-areas-width (0) : When not 0, scale the image to this width (px).
-
ng-areas-extend-data each area will have the properties defined on this JSON object. This can be used when you have multiple images with areas on them and you want to know to what image belongs a area-box. You could also use this to create tags to identify the fields.
-
ng-areas-allow : Json Object
i.e. ng-areas-allow="{'edit':true, 'move':true, 'resize':false, 'select':true, 'remove':false, 'nudge':false}"
- edit (true) : When set to false, unset allowMove, allowResize, allowSelect and allowDelete
- move (true) : When set to false, Areas can not be moved with a drag & drop.
- resize (true) : When set to false, Areas can not be resized.
- select (true) : When set to false, Areas can not be created.
- remove (true) : When set to false, Areas can not be removed.
- nudge (true) : When set to false, Areas can not be moved with arrow keys.
Events handlers
Three events are fired by the plugin:
- ng-areas-on-remove (null): fired a selected area is removed. arguments : (event, id, areas, area)
- ng-areas-on-add (null): fired when a selection is released. arguments : (event, id, areas, area)
- ng-areas-on-change (null) : triggered when the event "changed" is fired. arguments : (event, id, areas, area)
Event listeners / subscribers
So far one event is listening by the plugin:
- on "ngAreas:renameByAreaId"
usage
$scope.$broadcast("ngAreas:renameByAreaId", {
areaid : areaid,
name : "a new Label or Name for this box"
});
