Sophisticated HTML5 Image Map? - image

I have an image of a living room, which I'm turning into a menu for a new site I'm working on. The idea is that you can click on certain items in the room, like a chair, desk, couch, etc and get taken to the desired page. I'm wondering if there is a clever way of doing this. Since the items are not simple shapes, I don't want to use a standard image map.
Thanks for you help!

I'm answering because a Google search brought me here...
Because you asked for a tool:
GIMP Has a really good Image map creation function.
Open your image in GIMP and select Filters > Web > ImageMap
From there you can create image maps by drawing on the image. Saving will generate HTML you can then tailor to your needs.

This tool looks to be a solid image mapper: http://www.image-maps.com/
I'd suggest doing this with a canvas and SVG's, it would make this quite a bit easier, and more professional.

As Korvin mentioned, doing this in SVG is probably the easiest option, because you can attach events to objects in SVG rather than having to manually specify a particular area in which to listen for events.
If you go this route, I recommend using the RaphaelJS library which has a nice syntax and the advantage of working in IE pre version 9. Here's a demo which, although it uses onmouseover instead of onclick, it might be close to what you're trying to achieve:

Is there a way to manually scroll a large image in PowerPoint?

Preview of what I'm looking for
Hello, I'm looking for a way to manually scroll a large image in PowerPoint. In the image there's an example of what I'm looking for. I want to have a preview of the image that I can scroll through and the actual image that moves accordingly to the scrollbar.
Thanks!
I assume you want this in SlideShowView? For sure this can be achieved only by scripting. Essentially you would have to program buttons for up and down movements and use vba do apply this to the image. The preview is a bit more complicated since you would have to do some math too to achieve the conversion in the size differences. All in all a job for a programmer. Are you looking for programming support here?

How can I draw images, lines, etc. on google maps

I'm investigating how I might best create an app that allows drawing of arbitrary shapes, images, etc. on google maps, based on lat/lon coords of the shapes or coords/rotations for images. Surprisingly I haven't found anything out there that offers much in the way of flexibility. Scribble-maps has created something close to what I'd aim for, but they're using flash. I'd ideally like to build something that draws on the google maps html map.
I suppose I could build a div, lay it on top of the map, and if I can listen on the map scroll/zoom events I should be able to figure out how to do everything myself. Thoughts?
You need to use overlays, check the Google API documentation.
There's an example of mouse interaction to draw lines in the Polyline Arrays section. To show images have a look at the Ground Overlays section.
I know this is a very a late response, but we have launched an API for Scribble Maps. You can check it out at http://www.scribblemaps.com/api/

Lightbox for Flex

Ey. I've seen the other post about Lightbox gallery effect for Flex, but after having played around with it I cant seem to get it to work 100% (The image is as small as the thumb, and I cant make it bigger). And this also lacks some functionality I'd like to have.
So, one example would be, of course, this: http://lokeshdhakar.com/projects/lightbox2/
If you click any image on the image set you can swap between them with an arrow. This is what I'd like to have.
Also, it would be nice if it was possible to display the thumbnails for the other images in the same set under the bigger picture(when one image is already clicked).
I've tried to search for components like this, but I cant seem to find any other.
If any of you know of any nice components or snippets of code for this kind of effect then please let me know! =)
Kind regards,
Stian Berg Larsen
  
EDIT:
So I've searched around and tried a number of examples, but I cant seem to get any of them to work. There is always an error, and none of the examples are exactly what I want.
I simply need a way to show images like Lightbox. With a prev/next arrow and maybe a close button. Nothing more than that. How would I go about making this, or use an existing component?
Im using a TileGroup to hold all my thumbs (so that they will fill out the width of the Group with more images if there are room for it). If it's possible to generate this list of thumbnails dynamically too then that would be great, but basically what I need is to show images with a Lightbox style when I click them.
Thanks! =)
I ended up just making my own lightbox effect. :)
Created an Actionscript class (based on Group) and added image loading functionality, prev/next/close buttons and borders and such. Works like a charm :)

Set a country background to my Google Geomap

A few days ago I've explored geomaps and, however, it turned out to be easy to change the properties of the elements.
But I have two questions:
I'd like to add rivers and forests on the maps. So Ive considered to set a background image instead of the geomaps figure. But I can't find a way to get this one fixed. Is there a way to set a background picture for a country or region?
How can I change the shape of the "bubbles" when you select a city e.g. "London"? I'd like to change it to a square.
Thanks in advance for your help!
Unfortunately what you're looking for is not available in geocharts in their current implementation.
Using a background image is possible in the sense that you can use CSS to make all shapes in the map transparent, and use a background image in the div to make it appear as if the little circles are being drawn on a map with forest and rivers, but you will run in to two big hurdles:
Your map will need to be identical in size/layout to the Google Maps SVG
If Google ever changes the SVG they use (or the view/projection they use) you will need to edit yours too
This isn't ideal, obviously. You could work around it by creating custom javascript to write rivers and forests on your map, but that is going to be a huge headache (especially if you are using multiple maps/views).
As for the circles, you can't change them to squares without hacking the actual SVG in the background with javascript. While this is definitely possible (if you're really good with SVG/Javascript), it again isn't using any of the fancy features of geocharts, and is more just a custom solution that will have to be updated if/when google updates their API.
Rather than doing it that way, you may want to look in to the same implementation on google maps itself. That will allow you to use custom markers, draw custom shapes, etc. with a lot more flexibility (and a much more stable API).

Preventing web images from being taken

I've been looking around to see if there exists a good way to prevent viewers from using their right click options to download images that I upload to my website.
I know that people can look at the image url in the page source, and was wondering if you suggest a way to prevent them being taken, by disabling the save image option.
This is an unsolvable problem.
As long as you actually want people to see the images, you cannot prevent them from saving them via a number of methods (e.g. screenshots). All measures you might think of will just annoy your users, without actually preventing them from doing what they want anyway. Also consider that the people watching those images will have some interest in them (otherwise they would not watch them in the first place), so there we already have a motive for them to keep a copy.
The only way to reliably prevent people from saving the images is to never let them copy them onto their computers in the first place (and remember: showing something on another computer always entails making a copy).
One solution could be to invite people into a place where they can view the image on a screen which you control, and not let them take any pictures. Think of modern cinemas where security people with night sights watch the spectators and pull out those who might have been handling any camera like device.
If you want to make it even more difficult, do not use an IMG tag. Instead, define the image using CSS with the property 'background-image'. To make it even more tricky, define that property at runtime using JavaScript that was placed on the page using base64 encoding.
You can try this...
onload=function(){
document.oncontextmenu=function(){return false;}
}
This will disallow the operation of the context (right mouse button click) menu...
If a user knows what they're doing they can get around this, though.
I suggest not doing this. It's annoying and you're not actually protecting yourself.
If you must, jQuery makes it pretty easy to disable the right click menu:
$(document).ready(function(){
$('img').bind("contextmenu",function(){
return false;
});
});
Just make your images so ugly no one would want to take them.
Seriously, what are you worried about?
If you use the Microsoft Ajax Seadragon Deep Zoom viewer for you images then you can present your images as lots of overlapping tiles - a real pain to stick back together, difficulty depends on images size, but for hi-resolution images it makes 'printscreen' the only option for those wanting to steal stuff.
Incidentally the contextmenu thing works on divs better than images (things bubble) and you don't have to offend people by doing no click on the whole document.
To do it by class, e.g. with Prototype:
$$('.your-image-container-class').each(function(s) {s.oncontextmenu=function(){return false;}});
