Pracuję na płótnie, teraz mogę zapisać do DB i mogę zmienić obraz tła na wybraną z listy obrazów.Zapisz zdjęcie w wybranym tle.
Mój problem polega na tym, że próbowałem zapisać płótno z tłem, na którym zapisany obraz pokazuje mi tylko losowanie, ale czy tło obrazu ... czy ktoś mi w tym nie pomoże?
Pozdrawiamy!
Oto kod:
<script src="js/drawingboard.min.js"></script>
<script data-example="1">
var defaultBoard = new DrawingBoard.Board("default-board", {
background: "#ffff",
droppable: true,
webStorage: false,
enlargeYourContainer: true,
addToBoard: true,
stretchImg: false
});
defaultBoard.addControl("Download");
$(".drawing-form").on("submit", function(e) {
var img = defaultBoard.getImg();
var imgInput = (defaultBoard.blankCanvas == img) ? "" : img;
$(this).find("input[name=image]").val(imgInput);
defaultBoard.clearWebStorage();
});
$(function() {
$("#file-input").change(function(e) {
var file = e.target.files[0],
imageType = /image.*/;
if (!file.type.match(imageType))
return;
var reader = new FileReader();
reader.onload = fileOnload;
reader.readAsDataURL(file);
});
function fileOnload(e) {
var $img = $("<img>", { src: e.target.result });
var canvas = $("#default-board")[0];
var context = canvas.getContext("2d");
$img.load(function() {
context.drawImage(this, 0, 0);
});

// with this code I can change the background
