Exporting & Saving One thing that SVG can’t do is save the resulting image as a bitmap. It’s easy for <canvas> because the element is already a bitmap in the first place! The canvas can export its image to a data URL (e.g., data:image/png;base64,iVBORw0KGg...). This data may then be rendered in the browser, which could then be saved or dragged to the desktop, used in a new canvas, and so on. The browser must support PNG images, and it may have varying support for GIF and JPG. For our example, we’ll stick with PNG since it supports alpha transparency, and where we haven’t drawn on the canvas, it’ll be transparent. To get the data URL, we simply call canvas.toDataURL('image/png'). Note that we’re calling toDataURL() on the <canvas> element, not on the 2D context. This is because we’re getting all the pixels in the canvas, not just the pixels in a particular context. So taking the example we’ve put together already, we’ll make the browser redirect to a PNG version of the image when a user clicks on the <canvas> element (a contrived example, I know!): canvas.onclick = function () {  window.location = canvas.toDataURL('image/png');};

Augmented reality, or the blending of the real world with computer graphics on the fly, is one of the most exciting fields in tech right now

Zugara, an interactive marketing agency, has built something a bit more practical for the time being. It’s put together the Webcam Social Shopper, offering a way to help you try on clothes online from the comfort of your bedroom.

t lets you overlay a static image on top of your body and pretend you’re wearing it. Which is sort of a start.

The iPad has a bigger screen, and so it has a bigger resolution. With the iPhone 4, however, Apple did something different: they increased the resolution without changing the physical size of the screen. This makes for a higher pixel density, pixels are smaller and more tightly packed. In one square inch of the iPhone 4’s screen there are around 106 thousand pixels (at 326 PPI, or Pixels per Inch), while the older models have only about 26 thousand (at 163 PPI) in an inch – 4 times less! This makes graphics on the screen seem like continuous lines, because your eye can’t see the individual pixels. Apple calls this technology the “Retina Display” because they claim the human eye (the retina) can’t physically see the pixels at this resolution.

Using Two Images The official way of adding high-resolution support to your application is by having two versions of each Image, one in “regular” resolution and one in double resolution. Whenever your application is viewed on the Retina Display, the larger Image will be loaded automatically. This method allows for full and precise control of how your application will look in each case, and is very easy to apply to your existing applications. The full size Image file should be named however you want, such as “Button.png”. Use this Image name in your code and Interface Builder wherever you want to reference the Image. The double-size Image should be twice the size of its matching smaller Image and named exactly the same with “@2x” appended to the name. In our example, we would name it “Button@2x.png”. Unfortunately, this technique will not work on the iPad; a pixel-doubled application will not load the higher resolution resource. This will probably be addressed in the future iOS 4 update which is scheduled to come to iPad this fall.

At Adobe’s MAX conference the other night, that message was made manifest with a live demonstration of a Flash to HTML5 conversion tool, which is currently in the works. The tool is incredibly impressive in that it can convert full Flash animation into HTML5 on the fly

Watch the demonstration video to get an idea of how users will be able to take elements from within the newly converted HTML5 code to re-insert elsewhere on a web page

Those animations or interactions will now be viewable on all kinds of devices — including the iPhone () and iPad. This is where we think that this HTML5 conversion tool has real possibilities. It’s one thing to be able to convert a movie or animation

Google () announced Wednesday morning that it has begun rolling out mobile editing for Google Docs (). The update isn’t yet available for everyone, but it should be available to all over the next few days.To date, only Google Docs spreadsheets have supported mobile editing. When the the update hits, all Google Docs documents will be editable on devices running Android () 2.2 (and higher) and iOS 3.0+.We’ve not been able to test it out yet, but Google has released a little video — as seen above — showcasing the new mobile editing capabilities of Google Docs.

The problem is amplified when saving for Retina, where there’s twice as many images, and the 1× images must match the 2× images precisely. The best solution I’ve come up with so far is: Build your design at 1×. Use copy merged to save all the 1× images. Duplicate the entire folder containing the 1× images. Use Automator to add @2x to all the filenames. Open each @2x image and run the Scale by 200% Photoshop action. This gives you a file with the correct filename and size, but upscaled content. Scale your main Photoshop design document by 200%. Use copy merged to paste the higher quality elements into each @2x document, turn off the lower quality layer, then save for web, overwriting the file.

So why, then, would it be better to work with a 16-bit image? One word - flexibility. When you're editing an image in Photoshop, sooner or later, if you continue making edits, you're going to run into problems. The most common problem is what's known as "banding", where you've lost so much detail in the image that Photoshop can no longer display smooth transitions from one color to the next. Instead, you get an ugly stair-stepping effect between colors and tonal values.
