I have a requirement in the project I am working on for a piece of JavaScript which will allow the user to pan over and zoom in and out of a large image.
Unfortunately, my experience with JavaScript is limited.
Does anybody know of a free script out there which would satisfy my requirements?
There is a jquery ZoomImage plug-in to my opinion which would be good use for this case..Examples for code are here or here.
There is one that also uses a zoom toolbar next to the image

It has been a long time since I have had to do Image Mapping! Probably like 4-5 years.
The last time I achieved this using the tag and creating tags for polygonal shapes. This of course works, and is still supported html, even in HTML5. Question is though, is this still a good way to go for image mapping? Or should i scrap this direction and aim to use Canvas or SVG techniques instead?
There are a couple of factors in regards to the decision:
The client uses IE7, so the solution has to work with IE7 and IE8, hence me thinking not to use SVG or Canvas, it would be easier I guess to use the old school map tag, at least it will easily work across all platforms.
The Map has quite custom styles (strokes around the areas with a margin gap too)
Each area has a rollover state, with a popup with content unique for each region. This will have to be achieved with JS. Are there any issues using JS to interact with the DOM structure of the map using map tag?
It's not essential, but I would to make the map somewhat responsive to the viewport.
Using the tag frankly feels really old school, dated and dirty. But, to be honest for my case, it seems like the most suited solution. What does everyone think?
Any feedback welcome,
Thanks,
Craig
For your requirements I think best suite is SVG. By some work around you can make use of all time favorite jQuery with SVG and build cool stuff so quickly. I was able to develope a ticket booking tool on theaters with SVG maps within two weeks.
Also now every one needs every thing on mobile and it works on mobile with just no efforts.
Try to convince client to upgrade IE, that will be best for you. All the best.
I'm searching for a JS framework that is compatible with CreateJS and KineticJS to create tooltips on a canvas.
I'm making an app that uses both CreateJSs and KineticJS and I want to draw tooltips on both of them (without using two libraries).
Thank you.
There are dozens (if not hundreds) of tooltip scripts out there—just ask google!
I assume that since you want to support both createJS and kineticJS that you must have already coded the trigger that requests a tooltip.
With that in mind, here is one tooltip library: http://www.opentip.org/documentation.html
It’s open-source so you can use/modify it freely.
It’s controlled by javascript so you have createJS/kineticJS independence while still working in JS.
It uses html canvas to display the tip so customizations should be familiar to you.
The tip-canvas is temporary and it floats so it should not interfere with your main canvas.
It allows you to offset the tooltip, so your code can exactly position the tip as you need.
For my recent project I need to add a specific text animation - to achieve the effect of a pen writing some text on canvas.
I would like to hear your thoughts what would be the best way how to do that based on your experience?
Could you point me in the right direction and include some references where I could learn how to do that?
I am currently using Twitter Bootstrap Framework for Frontend.
http://lazylinepainter.info/
This is just the tool you need
There are a lot of libraries helping you to animate your content without using canvas (not cross browser...)

I am looking for a Flash based image uploader with resize and possibly rotate function.
I have checked many possibilities, and the very best in simplicity and unser experience I found is Kroppr at a very affordable €29/license.
The downside is, it comes with encrypted PHP code to bind the product to a subdomain. That is understandable, but while I'm perfectly happy to pay money for a tool as great as that, and ready to sign all sorts of legal agreements to protect the license, I am not ready to use encrypted PHP code, especially not from an outlet that doesn't even have a postal address on its web site.
Does anybody know an Open Source or commercial solution that comes close to Kroppr and ships with source, or allow for full customization and free definition of the server-side backend?
The features in detail:
Rectangular selection to crop image, slider or similar to zoom
Optionally: Rotating
"Accept" and "Reset" buttons, "accept" triggers a call to the server and submits the image
Full visual customizability (at least background and text colours)
Possibility to rename all controls
The server side technology would preferably be PHP.
http://deepliquid.com/content/Jcrop.html i love this one, every easy to use and tons of features. i know your searching a flash cropper but this question is tagged with js too so....
I found these three image utilities during my search:
Flex Image Cropping Component
HOW TO CROP AND RESIZE AN IMAGE USED AS BACKGROUND FOR CANVAS
Building an image-viewing widget with ActionScript 3.0
The first one is an open source flex component using an MIT license. The second one is a how to,with full source available. It doesn't have a sizable box, but it seems ok otherwise. The last one is also a how to article from adobe.com with source available.
Here is a list of good javascript based croppers:
Yahoo! UI ImageCropper
Jcrop
MooCrop
UvumiTools
PHP & jQuery Image Upload and Crop
Here is a list of action script based croppers:
Flex Image Cropping Component
Image Crop

I would take a look at the free pixlr editor and their developers API : http://pixlr.com/wiki/developer
I've used RadActive's I-Load component before, with great success. The UI customisation options are a little limited, but as far as functionality goes, I'm pretty sure it meets all your requirements.
EDIT: You don't specify what server-side technology you're using (if any). I'm pretty sure I-Load is designed for ASP.NET - this may or may not be an issue for you.
This is also a nice once and its only $10.

Still doesn't have image rotation/cropping. I most definitely do plan to add that, but after checking out all the things I could find I still wasn't happy. I researched out all the particulars and just ended up building my own. You're welcome to use it if you like and haven't found something else by now. Keep checking the link, I'll update it to include the rotation and crop feature along with multiple image uploads.
Something like this?

I'm perfectly happy to pay money for a tool as great as that
To carry out the responsibility of posting the answer for stackoverflow users, here is part of the crop image code:
var tNewImage:BitmapData=new BitmapData(mouseX-vCropX,mouseY-vCropY,true,0);
iImg.getChildAt(0).x = vSize/2 -vCropX;
iImg.getChildAt(0).y = vSize/2 -vCropY;
tNewImage.draw(iImg);
Where iImg is the movieclip containing the image with the image center positioned at (0,0) , vSize is the image dimension, vCropX and vCropY is the top left cropping coordinate. The tNewImage BitmapData is used for constructing the new Cropped Bitmap image
is there any library or component that allows photoshop or pdf style zooming where i have images that i want users to be able to click to zoom in and out and i want to support being able to zoom in a number of times and zoom out a number of times
i want the equivalent of every user having the ability to do stuff like this:
https://addons.mozilla.org/en-US/firefox/addon/139
Have a look at:
the jQuery gzoom plugin
shiftzoom (example here)
the jQuery MapBox plugin (works with scroll whell and I'm sure you can stick + / - buttons)
the MooZom plugin (works with scroll whell and I'm sure you can stick + / - buttons)
Anything Zoomer is also nice
Then, there is Zoomorama which is an alternative to Microsoft's Seadragon if you don't mind using flash.
You can use Google Maps API to do that. All you need to do is to generate custom map tiles. There is a nice tutorial here.
EDIT: Just found another site that uses the same technique.
I have also found some alternative solutions that are not based on Google Maps API (1st is the best in my opinion):
Microsoft's Seadragon

and other questions about this topic:
Image Zoom using javascript?
Javascript for zooming and panning an image
Javascript / jQuery image zoom plugin
EDIT: If you have really large images, you can upload the files to GigaPan(SM) and embed them in your website.
Have a look at GWT too...
here is a zoomer made in GWT:

Silverlight Deep Zoom is one cool way if your environment permits it.
Here's a kind of overkill example of it : http://memorabilia.hardrock.com/
Also from a Flash advocate. And some more stuff - and maybe most fun of all a 13 gigapixel image.
