I am using selectareas.js to select some parts of the image with mouse event and getting coordinates x,y,z of the image, as I am selecting multiple areas of the image, all the values are printing/console in my browser correctly.
Now I am trying to Show all those selected coordinates of image areas as a new image in a different canvas/div on a button click event.
So technically when I am selecting 2,3 or 4 areas all coordinates values prints like this in an array
0: {id: 0, x: 10, y: 20, z: 0, height: 100,width: 60} 1: {id: 1, x: 159.5, y: 286, z: 0, height: 73,width: 220} 2: {id: 2, x: 464.5, y: 300, z: 100, height: 117,width: 221}Now I am trying to figure out how to show these coordinates as a different new image on my page or downloads all as a new image by converting into base64.
$(document).ready(function() { $('img#example').selectAreas({ minSize: [10, 10], onChanged: debugQtyAreas, width: 1000 }); $('#btnView').click(function() { var areas = $('img#example').selectAreas('areas'); displayAreas(areas); }); }); var selectionExists; function areaToString(area) { return (typeof area.id === "undefined" ? "" : (area.id + ": ")) + area.x + ':' + area.y + ' ' + area.width + 'x' + area.height + '<br />' } function debugQtyAreas(event, id, areas) { console.log(areas.length + " areas", arguments); }; function displayAreas(areas) { var text = ""; $.each(areas, function (id, area) { text += areaToString(area); console.log("Here") }); output(text); }<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script> <script src="https://cdn.jsdelivr.net/npm/jquery-select-areas@0.1.0/jquery.selectareas.js"></script> <div class="image-decorator"> <img alt="Image principale" id="example" src="https://raw.githubusercontent.com/360Learning/jquery-select-areas/master/example/example.jpg" /> </div> <table> <tr> <td class="actions"> <input type="button" id="btnView" value="Display areas" class="actionOn" /> <td> <div id="output" class='output'> </div> </td> </tr> </table>
