I’m using the dojo toolkit and want to try Image Cropper on the same page.
It seems that these two libraries don’t work together…
(conflict between IC classes and dojo.io.IframeIO)
Anyone knows how to solve this issue ?

Thx !!

I found my answer through a previous post.

Thanks Adam B! Check out post #147.

I modified it a little bit for what I wanted, but this was just what I needed.

I’m having problems with IE.
I set my Event observe like this:

Event.observe(
‘testImage’,
‘click’,
function() {
new Cropper.Img(‘testImage’,{
minWidth: 10,
minHeight: 332,
onEndCrop: onEndCrop

});
});
So, when I click on the image (that have ID=”testImage”), crop works normally, but the image get blank. I can do everything that Cropper demos show, but the image is now a “white retangle”.

I noticed this bug just in IE… Firefox works perfectlly. What it can be?

Thanks!

By the way… the problem I reportted is for IE 7

Yes, It is inside a table. I tested without table, just the img tag and it works. Is there a way to fix it? Because I won’t be able to modify the page structure.

Thanks for the “on-the-fly” answer and congrats for this app.

i have a problem with it when i use it in layers, “advanced layer popup” to be exact. http://www.dmxzone.com/ShowDetail.asp?NewsId=12769

when the crop script is put in the layer popup and run from there, when you go and crop the image in internet explorer 6 or 7 the crop area i like an xray and puts a hole through the layers to the page underneath. anyone give me any advice on how to correct this problem?
the demo above works fine, just when you combine the cropper and popup layer is where the problem starts with the xray.

Full details are here in this thread on this forum below.
can anyone help me out here??

Thank you for this amazing tool!

I have a couple of questions/problems about it.
1. I would like to crop again the same image (without using the remove() and reset() methods), but it seems it doesn’t work in IE7 (you can move the handles, but it doesn’t update coordinates). If I use either the remove() or reset() methods, I get an error, but the line of code indicated doesn’t exist. In FF works without a problem in both cases.
2. I would like to crop a new image, but the cropper still shows the previous one (although when the crop is made, it’s a piece of the new image).

I’m using the ImgWithPreview and a couple of functions to show and hide the div when called. I have an iframe which passes the URL of the image loaded to the showDiv function, and when the user presses the submit button for cropping the image, the hideDiv function passes the coordinates to the iframe which performs the cropping in PHP and shows the result in the iframe.

Thank you in advance for your help.

Gret tool, I have it doing almost everything I want. Combining it with imageCFC I can upload, crop and rotate the image.
But one other feature I need is that if a user uploads a big image, I need to resize it for display purposes only so it fits on the screen, but crop the true image.
So if for example they uploaded an image of 800×600, I would set the img display height and width as 400×300, but I need the crop to occur on the real dimensions of the image not the dimensions that they select on the page.

Any suggestions ?

Any reason why the uncompressed version doesn’t work? (the compressed version works [almost] fine for me .. but the compressed version doesn’t seem to work at all).

In my (german) example at http://familientagebuch.de/rainer/2006/50.html#5 is left a thumbnail and the imagemagick convert tools cut from the original size.
It is very easy and similar to http://familientagebuch.de/rainer/2007/09.html#i95

First of all: great work! I’ve seen quite a few image-cropping utilities but your solution is really nice (and doesn’t hurt my eyes).
What do you think of this feature: update the dimension/position info on Drag? So we could have a live update of how big our Croparea is and where it is (like in photoshop). That would really help.
[sorry, but english is not my first language]

I think you already heard this many thimes, but here’s one more time: GREAT WORK!

I tried to integrate your script in a netbeans Visual Web Pack project. There where two problems I faced, here are the solutions:

1. The scripts have to be included in the following way(i think this is true for all VWP projects):
var fake=null;
var fake=null;
var fake=null;

2. You should use a plain GraphicImage component, and put it into a GroupPanel. Other ways the selection box won’t appear, or there could be problems with the position. If you put it into another type of panel then it’s the same bug what fialik wrote about.

It seems that the code did’t appear right
so it was:
script src=”cropper/lib/prototype.js” type=”text/javascript”>var fake=null;

I am using crop with preview, but it appears the preview size is tied to the minWidth and minHeight of the crop. This is a shame, I cant have a large preview and a small minimum size which seems very strange.

Can you change it so that there is a specific previewWidth and previewHeight that we can set externally and still be able to have a smaller crop area.

Thanks

It would be very nice if you could nudge the ‘size’ of the crop as well as the position. Something like:
CTRL+LEFT will make it smaller width
CTRL+SHIFT+LEFT will make it smaller width in bigger jump
CTRL+RIGHT will make it larger width
CTRL+SHIFT+RIGHT will make it larger width in bigger jump

CTRL+UP will make it smaller height
CTRL+SHIFT+UP will make it smaller height in bigger jump
CTRL+DOWN will make it larger height
CTRL+SHIFT+DOWN will make it larger height in bigger jump

Basically you are moving the right edge or the bottom edge.

Is this code is used for crop a some portion of site?

I’m testing the component but I have a problem.
The image is displayed in an IFRAME. I added the code to the page that is displayed in the IFRAME. But nothing happends when I click on the image.

What’s wrong ?

For a given image I have used
//zoomWidth: Final image width after applying zoom(in/out)
//zoomHeight: Final image height after applying zoom(in/out)
//x1,y1, cropWidth and cropHeight are same as x1, y1 , w & h in above example

image = ScaleToFixedSize(image, zoomWidth, zoomHeight);
image = Crop(image, x1,y1,cropWidth,cropHeight);

private Image ScaleToFixedSize(Image imgPhoto, int Width, int Height)

{
int sourceWidth = imgPhoto.Width;
int sourceHeight = imgPhoto.Height;
int sourceX = 0;
int sourceY = 0;
int destX = 0;
int destY = 0;

float nPercent = 0;
float nPercentW = 0;
float nPercentH = 0;

nPercentW = ((float)Width / (float)sourceWidth);
nPercentH = ((float)Height / (float)sourceHeight);

//if we have to pad the height pad both the top and the bottom
//with the difference between the scaled height and the desired height
if (nPercentH

I implemented the cropper but found a few problems :

1. After using the arrows to move the crop area, the callback function OnEndCrop is not called. How to display the coordinates after each move with the arrows ?

2. When displaying an initial crop area on the image (onload), the arrow keys do not work. We first have to move the area a bit to make the arrows work.

Hi,

Can I save the cropped image using code ????

For the problem in post 223(“2. When displaying an initial crop area on the image (onload), the arrow keys do not work. We first have to move the area a bit to make the arrows work.”) additionally: – if the ratio is set and the image is in the initial state, if the side of the image is dragged to the right, or up, the selection box jumps out of the image. If the image is moved a little then there are no problems. This seems to be some initialization problem, so isn’t there a way to set the fields of the image crop after the instantiation to simulate an image move without explicitely having to move the image by hand?

Thanks!

test2 error
help me

两个测试，试一下，可以发现，测试一没问题。因为图片不大。

但，测试二，问题来了。大图片，我虽然按比例缩小显示了，但裁减的时候，其实还是在原大小上裁减。所以造成定位不准。

我呼唤高手，怎样做到，让大图缩小显示，裁减的位置也是在缩小的图上进行的。

good job !
thanks !

这几天一直在做这个，终于可以实际应用了：

http://www2.zhuatu.com/crop/index.asp?testImage=2.jpg

只是还有几个问题，一直无法解决：

1、图片放大缩小后，那个透明层没有随之放大缩小。找不到解药。
2、图片下那几个文本框，无法直接填数字。怎样改成直接填数字也可以？
3、裁减后为什么只能另存为bmp？我想另存为jpg。

pls improve:
add the function of zoom in/out,
input data directly to textfield

It doesn’t seem to work with Scriptaculous 1.6.5. Can anyone confirm?

AMAZÄ°NG!!!!

i would like to use the selected image on a new image in order to zoom the selected image some ideas pls
to use in a state map
how to use the selected image as a new image
and how to avoid the darkening of the image is there an option fej same color and a rectangle with border to select
thanks

I like your updates! They are very useful. Thanks.

Hi all
I have problem with IE 6. I can’t load the page. The problem is with scriptoculous.js file. This script writes to the output only libraries given as script params and ended. :/ There is no following page code. When I am removing this file from code, all page is loaded. Under firefox 1.5 there is no problem Thanks for any help

hi
I have found the solution. I am including all needed .js files directly, without using scriptaculous.js.

and I am moving onEndDrop function from .html file to other .js file which is included to HTML file

that’s solved problem with using tools at IE 6.

Wow! This script is something! Thank you so much for seeing the effort.

... But I also have a small problem, as I’m not that much of a javaScript developer. All of the test HTML scripts work just fine, but when I include the script to my site, it works quite randomly. So of course I’m a bit confused ‘cos I’ve ran out of knowledge here. I’m building a feature that users can upload an image if they want and its resized on the server side. Later on they can crop the image (just as an extra feature) on their browser. So the image data is read from a database blob, user can define the crop area on their browser and then the co-ordinates are sent to server and voila! If I’ve understood correctly, that Event.observe(‘load’ ...) should take care that the page and the image is loaded before the script is run. But I think 4 times out of five I’ll get 2 errors. a) Draggable is not defined (line19/cropper.js) and new Cropper.Img has no properties (on the HTML page). So it seems to me that the script is run before the image is loaded. Can someone give me a gentle push towards how to solve this problem? Like I wrote, I’m bit confused since sometimes the script works and sometimes it doesn’t… Tried all of the trick I know, but of course that is not a lot :)

But keep up the good work! This script is really something!!

hmm I am seeing that code was removed from my last post Sammy I had the same problem under IE 6 My solution does not use scriptocoluos.js I am inluding all scripts directly into page
src=”/mim/wspolne/.js/cropper/lib/prototype.js” defer=”defer”>
src=”/mim/wspolne/.js/cropper/lib/builder.js” defer=”defer”>
src=”/mim/wspolne/.js/cropper/lib/dragdrop.js” defer=”defer”>
src=”/mim/wspolne/.js/cropper/cropper.js” defer=”defer”>
src=”/mim/wspolne/.js/cropper/onEndCrop_function.js” defer=”defer”>
The order is important.
The last one file consist of my implementation of onEndCrop and code used for creating Cropper object. I hope it helps :)

I have just downloaded ther cropper and it is great. just wondered if there is any way to change the ratio of the selection box, after the cropper has been initiated? IE, i have a selection box with different ratios in, and i need it to change without a page reload.

Many Thanks.

still waiting for a reply, been months now. If you dont have any idea, just say so, come on. IM not going to give up until i get an answer, IM not like that. IM persistent.

This demo looks really cool, and I was able to get it to run without a problem on my server. My only question is once the image has the crop marks set.. then what? How do you save that cropped image, or pass the information on? Am I missing something? I guess I am looking for a button that says “Crop Complete” or something, and when that is pressed, the image is saved in cropped form, and you move on to the next screen… is that possible?

Thanks!

Joe,

You use the callback mechanism. See the references to “onEndCrop” above. The callback mechanism will call some javascript code that you write. Mine sets a couple of hidden variables and then submits the whole page, then on the server side I process the actual cropping using the values from the hidden fields. There is no reason that you couldn’t do this in an AJAX way though. Hope that helps.

Cheers,
Dave

Love this cropping code, very very good stuff.

I’m utilising the previewWrap, but I’d like to set it to a specific size, not the minWidth and minHeight.

The reason: the actual picture that will be cropped on the server side is much larger than the one that I’m displaying, so I apply a ratio to the crop dimensions that I receive from your cropping code.

e.g. say the real image is a 1000 pixel square, I might display a 250 pixel square in the browser, giving a ratio of 4. So the dimensions and initial position I receive on the server must be multiplied by 4 before the real cropping takes place. Since everything is multiplied by 4, the minWidth and minHeight are only a quarter of what the real values will be will be, thus the previewWrap image is VERY small (too small to be useful). I’d like to manually set it to a different size.

I tried to modify the code myself, by changing all references in the preview specific code to use my static size rather than minWidth and minHeight. This was partially successful, but seemed to mess with the overflow a little.

Any ideas on which bits I should change to get it to work?

Cheers,
Dave

Thanks so much for this tool, it is really coming in handy. I am using it specifically as an admin tool to create flickr like tooltip-hotspots for photos in a photo gallery, in conjuction with JQuery. This tool makes it very easy!

However! One effect I’m trying to accomplish is to have the tooltip-hotspots that are already made to show up as dashed outlines within the image that the cropper is attached to. I’m doing this so that I can see where each hotspot will overlap as I create new ones. My problem is, that when I click on the image to use the cropper, my outlined hotspots disappear. They are generated divs that are attached dynamically using JQuery, and I have followed their instructions to make sure that JQuery is not clashing with the other libraries.

Is there a reason why the cropper tool would remove other divs? and is it possible to keep that from happening?

well done arvind kumar, you do that. Nice comment.

Hi.
I just have to say I love this cropper utility, and I’d like to use it in my own little image editor tool on the CMS I’m currently working on. You don’t seem to mention details about the license for this code. Is it allowed to use it in commercial applications?
Other than that, I’m wondering about the same thing as Dave Bolton (a few comments back).

Cheers

Dave,
when an image is uploaded, if it exceeds my maxwidth, I create a resized working copy setting this to the maxwidth and work out the ratio. This working image is what I use in the cropper, so the minWidth and minHeight still work fine.
You don’t want to resize the big image inside the cropper, this just doesn’t work right, and also means that the big image has to be submitted each time.
