I need to provide a means for a user to upload photos to their web site in jpeg format. However, the photos are very large in original size, and I would like to make the resize before upload option very effortless for the user. It seems my only options are a client side application that resizes the photos before uploading them via a web service, or a client side JavaScript hook on the upload operation that resizes the images. The second option is very tentative because I don't have a JavaScript image resizing library, and it will be difficult to get the JavaScript to run my current resize tool, ImageMagick.
I'm sure this is not too uncommon a scenario, and some suggestions or pointers to sites that do this will be appreciated.
In 2011, we can know do it with the File API, and canvas.
This works for now only in firefox and chrome.
Here is an example :
var file = YOUR_FILE,
fileType = file.type,
reader = new FileReader();
reader.onloadend = function() {
var image = new Image();
image.src = reader.result;
image.onload = function() {
var maxWidth = 960,
maxHeight = 960,
imageWidth = image.width,
imageHeight = image.height;
if (imageWidth > imageHeight) {
if (imageWidth > maxWidth) {
imageHeight *= maxWidth / imageWidth;
imageWidth = maxWidth;
}
}
else {
if (imageHeight > maxHeight) {
imageWidth *= maxHeight / imageHeight;
imageHeight = maxHeight;
}
}
var canvas = document.createElement('canvas');
canvas.width = imageWidth;
canvas.height = imageHeight;
var ctx = canvas.getContext("2d");
ctx.drawImage(this, 0, 0, imageWidth, imageHeight);
// The resized file ready for upload
var finalFile = canvas.toDataURL(fileType);
}
}
reader.readAsDataURL(file);
There is multiple-technology-capable Plupload tool which declares that it can do resizing before upload, but I haven't tried it yet. I have also find a suitable answer in my question about binary image handling javascript libs.
You have several options:
Java
ActiveX (only on windows)
Silverlight
Flash
Flex
Google Gears (the most recent version is capable of resizing and drag and drop from your desktop)
I've done a lot of research looking for a similar solution to what you have described and there a lot of solutions out there that vary a lot in quality and flexibility.
My suggestion is find a solution which will do 80% of what you need and customize it to suit your needs.
I think you need Java or ActiveX for that. For example Thin Image Upload
What jao and russau say is true. The reason being is JavaScript does not have access to the local filesystem due to security reasons. If JavaScript could "see" your image files, it could see any file, and that is dangerous.
You need an application-level control to be able to do this, and that means Flash, Java or Active-X.
Unfortunately you won't be able to resize the images in Javascript. It is possible in Silverlight 2 tho.
If you want to buy something already done: Aurigma Image Uploader is pretty impressive - $USD250 for the ActiveX and Java versions. There's some demos on the site, I'm pretty sure facebook use the same control.
Here some modifications to feed tensorflow.js(soo fast with it!!) with resized and cropped image (256x256px), plus showing original image under cropped image, to see what is cut off.
$("#image-selector").change(function(){
var file = $("#image-selector").prop('files')[0];
var maxSize = 256; // well now its minsize
var reader = new FileReader();
var image = new Image();
var canvas = document.createElement('canvas');
var canvas2 = document.createElement('canvas');
var dataURItoBlob = function (dataURI) {
var bytes = dataURI.split(',')[0].indexOf('base64') >= 0 ?
atob(dataURI.split(',')[1]) :
unescape(dataURI.split(',')[1]);
var mime = dataURI.split(',')[0].split(':')[1].split(';')[0];
var max = bytes.length;
var ia = new Uint8Array(max);
for (var i = 0; i < max; i++)
ia[i] = bytes.charCodeAt(i);
return new Blob([ia], { type: mime });
};
var resize = function () {
var width = image.width;
var height = image.height;
if (width > height) {
if (width > maxSize) {
width *= maxSize / height;
height = maxSize;
}
} else {
if (height > maxSize) {
height *= maxSize / width;
width = maxSize;
}
}
if (width==height) { width = 256; height = 256; }
var posiw = 0;
var posih = 0;
if (width > height) {posiw = (width-height)/2; }
if (height > width) {posih = ((height - width) / 2);}
canvas.width = 256;
canvas.height = 256;
canvas2.width = width;
canvas2.height = height;
console.log('iw:'+image.width+' ih:'+image.height+' w:'+width+' h:'+height+' posiw:'+posiw+' posih:'+posih);
canvas.getContext('2d').drawImage(image, (-1)*posiw, (-1)*posih, width, height);
canvas2.getContext('2d').drawImage(image, 0, 0, width, height);
var dataUrl = canvas.toDataURL('image/jpeg');
var dataUrl2 = canvas2.toDataURL('image/jpeg');
if ($("#selected-image").attr("src")) {
$("#imgspeicher").append('<div style="width:100%; border-radius: 5px; background-color: #eee; margin-top:10px;"><div style="position: relative; margin:10px auto;"><img id="selected-image6" src="'+$("#selected-image").attr("src")+'" style="margin: '+document.getElementById('selected-image').style.margin+';position: absolute; z-index: 999;" width="" height=""><img id="selected-image2" src="'+$("#selected-image2").attr("src")+'" style="margin: 10px; opacity: 0.4;"></div><div class="row" style="margin:10px auto; text-align: left;"> <ol>'+$("#prediction-list").html()+'</ol> </div></div>');
}
$("#selected-image").attr("src",dataUrl);
$("#selected-image").width(256);
$("#selected-image").height(256);
$("#selected-image").css('margin-top',posih+10+'px');
$("#selected-image").css('margin-left',posiw+10+'px');
$("#selected-image2").attr("src",dataUrl2);
$("#prediction-list").empty();
console.log("Image was loaded, resized and cropped");
return dataURItoBlob(dataUrl);
};
return new Promise(function (ok, no) {
reader.onload = function (readerEvent) {
image.onload = function () { return ok(resize()); };
image.src = readerEvent.target.result;
};
let file = $("#image-selector").prop('files')[0];
reader.readAsDataURL(file);});});
Html implementation:
<input id ="image-selector" class="form-control border-0" type="file">
<div style="position: relative; margin:10px auto; width:100%;" id="imgnow">
<img id="selected-image" src="" style="margin: 10px; position: absolute; z-index: 999;">
<img id="selected-image2" src="" style="margin: 10px; opacity: 0.4;">
</div>
Also not resize to a maximum width/height, but to minimum. We get a 256x256px square image.
Pure JavaScript solution. My code resizes JPEG by bilinear interpolation, and it doesn't lose exif.
https://github.com/hMatoba/JavaScript-MinifyJpegAsync
function post(data) {
var req = new XMLHttpRequest();
req.open("POST", "/jpeg", false);
req.setRequestHeader('Content-Type', 'image/jpeg');
req.send(data.buffer);
}
function handleFileSelect(evt) {
var files = evt.target.files;
for (var i = 0, f; f = files[i]; i++){
var reader = new FileReader();
reader.onloadend = function(e){
MinifyJpegAsync.minify(e.target.result, 1280, post);
};
reader.readAsDataURL(f);
}
}
document.getElementById('files').addEventListener('change', handleFileSelect, false);
You can resize the image in the client-side before uploading it using an image processing framework.
Below I used MarvinJ to create a runnable code based on the example in the following page:
"Processing images in client-side before uploading it to a server"
Basically I use the method Marvin.scale(...) to resize the image. Then, I upload the image as a blob (using the method image.toBlob()). The server answers back providing a URL of the received image.

form.append('name', event.target.files[0].name);

image.load(reader.result, imageLoaded);
};
});

I'm having trouble getting the dimensions of a series of images that are loading via PHP.
<?
$Ldir="imgs/liveGallery/"; // Directory where files are stored
if ($Lhandle = opendir($Ldir)) {
while (false !== ($Lfile = readdir($Lhandle))) {
if ($Lfile != "." && $Lfile != "..") $Lthefiles[] = $Lfile;
}
closedir($Lhandle);
}
sort($Lthefiles);
for ($Li=0;$Li<count($Lthefiles);$Li++) { ?>
<a href="<?php echo $Ldir.$Lthefiles[$Li]; ?>" class="ilightbox">
<div class="adj">
<img src="<?php echo $Ldir.$Lthefiles[$Li]; ?>" class="percent">
</div>
</a>
<?php }
?>
In the above code PHP is doing its job loading all the images from a nearby directory. The .adj class is formatting the <div> into a square and floating them all to the left so they tile the screen. It's also hiding the overflow so that no matter the dimensions all you see is a square.
My issue comes when trying to read the widths and heights of the images that are being loaded into that <div>. I want to have the image fit at a width or height of 100% depending on which is proportional to fill the square. Here's the jquery code I thought should work.
$(window).load(function() {
$(".adj").each(function() {
var $this = $(this);
var imageWidth = $this.children("img").attr("width");
var imageHeight = $this.children("img").attr("height");
if (imageWidth < imageHeight){
$this.addClass("aW");
} else if (imageWidth > imageHeight) {
$this.addClass("aH");
}
});
});
I don't seem to be capturing an image width or height at all, with what I wrote above.
I'm using fullpage.js and ilightbox.js which may be messing with my code, but I doubt it. I've also tried putting a modified version of this code inside the PHP for loop (without the jquery each function) and that doesn't work either. HELP!
Here's a link for you.
You can try somethig like
$(window).load(function() {
$(".adj").each(function () {
var $this = $(this);
var img = new Image();
//Set Image source
img.src = $this.children("img").attr("src");
//Wait for image to be loaded.
//Event will fire when image is loaded
img.onload = function () {
//Get Height and width
var imageWidth = img.width;
var imageHeight = img.height;
if (imageWidth < imageHeight) {
$this.addClass("aW");
} else if (imageWidth > imageHeight) {
$this.addClass("aH");
}
};
});
});
Note: I am not sure, this is a best practice
You have set the width and height in the css styling and not inline as attributes,
So attributes width and height are empty
$this.children("img").attr("width"); // .attr would not work
Should be
$this.children("img").css("width"); // .css is the method
And
$(window).load(function() {
$(".adj").each(function() {
var $this = $(this);
// when your referring same img multiple times, grab it in a variable
var image = $this.children("img");
var imgWidth = image.width(); // or image.css("width")
var imageHeight = image.height(); // or image.css("height")
if (imageWidth < imageHeight){
$this.addClass("aW");
} else if (imageWidth > imageHeight) {
$this.addClass("aH");
}
});
});
note .css() gives in the px'.
Example 100px even though you set the values in pt or em etc. After seeing your code since your comparing the values I would suggest .width() and .height() as they return integer values and easy to compare
jQuery documentation
Note that .width() will always return the content width, regardless of the value of the CSS box-sizing property. As of jQuery 1.8, this may require retrieving the CSS width plus box-sizing property and then subtracting any potential border and padding on each element when the element has box-sizing: border-box. To avoid this penalty, use .css( "width" ) rather than .width()
I make a form validation with javascript for field image upload but i stuck on point of how to validate image size(width and height) through javascipt for only 600 width and 300 height image is post by form .
So guys if you have any solution are demo code share with mi .
Thanks in advance !
You can use following function in javascript side to check whether image has desired resolution or not.
If it has correct resolution than proceed with form submission otherwise show error message.
var _URL = window.URL || window.webkitURL;
$("#file").change(function(e) {
var file, img;
if ((file = this.files[0])) {
img = new Image(); // create a Image object which contain height & width property of image
img.onload = function() {
alert(this.width + " " + this.height);
};
img.onerror = function() {
alert( "not a valid file: " + file.type);
};
img.src = _URL.createObjectURL(file);
}
});

I am new to Jquery and ajax.
I need to upload multiple images to server folder and store the details in a db table. After uploading, I need to display all images which set as 'active' in database.( I have looked into many codes which are not working for me)
After that I need to drag some images to an area and also need to store dragged images information in an another table.
Anyone have any idea?Please help me?
Thanks
Nowadays Dropzone.js is the best js plugin to upload multiple images using drag and drop.
official site. https://www.dropzonejs.com/
A complete example of the demo is here.
https://learncodeweb.com/web-development/drag-drop-images-with-bootstrap-4-and-reorder-using-php-jquery-and-ajax/
For uploading multiple images you can use this script. By using single browse button you can upload multiple images
$(function(){
var btnUpload=$('#photo_0'); // id of browse button
new AjaxUpload(btnUpload, {
action: 'url_to_upload_function',
name: 'uploadfile',
onSubmit: function(file, ext){
if (! (ext && /^(jpg|png|jpeg|gif|JPG|PNG|GIF|JPEG)$/.test(ext))){
$("#photo_div1").html('Only JPG,PNG,GIF files are allowed'); //
return false;
}
var path="<?=base_url()?>images/wait.gif"; //losding image
$("#photo_div1").html("<img src="+path+" width='32' height='32' style='border:#b6b6b6 solid 1px;'>");
},
onComplete: function(file, response){
response = jQuery.trim(response);
if(response=="error")
{
$("#photo_error").css("display","block");
$("#upload_photo1").html("");
}
else if(response!="error")
{
$("#photo_error").css("display","none");
$("#photo_div1").html("");
var path="uploads/"+response; //echo the image name from the upload function
var img="<table><tr><td ><img src="+path+" style='border:#b6b6b6 solid 1px;'></td></tr></table>";
$("#img_div1").html(img);// display the image in a div it will display only one image. If you want to add more you can code according to that by using append or something like that
$("#upload_photo1").val(response);
$("#photo_hid1").val(response);
} else
{
alert("error");
}
}
});
});

and for drag and drop you need to write another function for that you can refer this site or this
http://www.plupload.com/example_queuewidget.php
Here you can find a nice plugin that will help you to upload multiple images.I have used this and works well for me.
I have this script from JQuery.
<script>
// create custom animation algorithm for jQuery called "drop"
$.easing.drop = function (x, t, b, c, d) {
return -c * (Math.sqrt(1 - (t/=d)*t) - 1) + b;
};
// loading animation
$.tools.overlay.addEffect("drop", function(css, done) {
// use Overlay API to gain access to crucial elements
var conf = this.getConf(),
overlay = this.getOverlay();
// determine initial position for the overlay
if (conf.fixed) {
css.position = 'fixed';
} else {
css.top += $(window).scrollTop();
css.left += $(window).scrollLeft();
css.position = 'absolute';
}
// position the overlay and show it
overlay.css(css).show();
// begin animating with our custom easing
overlay.animate({ top: '+=55', opacity: 1, width: '+=20'}, 400, 'drop', done);
/* closing animation */
}, function(done) {
this.getOverlay().animate({top:'-=55', opacity:0, width:'-=20'}, 300, 'drop', function() {
$(this).hide();
done.call();
});
}
);
$("img[rel]").overlay({
effect: 'drop',
mask: '#789'
});
</script>
Right now it works by me clicking on an image. Then the overlay comes up with whatever is in the div. However I want to take out clicking the image and just have the overlay come up with an if statement in PHP. any ideas...im not very good at js.
EDIT:
yes im using the JQuery plugin Easing. However the overlay works great...and the overlay works by clicking on an image with the rel attribute like this
<img src="http://farm4.static.flickr.com/3651/3445879840_7ca4b491e9_m.jpg" rel="#mies1"/>
However I don't want to click on the images I want it to come up automatically.
<?php if ($whatever) { ?>
$(document).ready(function() {
$("img[rel]").click();
});
<?php } ?>
