Learn Photo Editing
As handheld devices become more and more powerful, many of the features that could exist only on a desktop computer are now possible on a mobile device. Once the purview of desktop apps such a Photoshop and the like, image editing and processing can now be accomplished on a phone.
Picasa is Google's online and desktop photo software, and it is the default photo service for unmodified Android phones. It is one of your choices when using the Share button, and it provides an easy way to upload a photo for embedding into a web page. Technically, Picasa and Picasa Web Albums are two separate products, but the distinction is fuzzy, since you can sync online and desktop photos. Picasa Web Albums is located on the Web at http picasaweb.google.com. Think of Picasa Web Albums as Google's answer to Flickr. You can upload photos and organize them into albums. Each album can have privacy settings, captions, tags, and location information (geotags). When using the service in a standard web browser, it also has facial recognition capabilities. So far this hasn't been translated into the phone version, but it's only a matter of time. The Xperia X10 has facial recognition software built into it, so it's not a stretch to imagine other phones will follow suit. Picasa doesn't...
Adobe Photoshop is probably the most trusted name in photo-editing software, and Adobe has expanded to also offer a mobile version of its product, as shown in Figure 9-12. It's not nearly as full featured as the desktop version, but it is considerably cheaper. The current price is free. Figure 9-12. Photoshop Mobile Figure 9-12. Photoshop Mobile Photoshop Mobile doesn't let you take new photos from within the program, but it lets you work with the photos you already have. Think of it as a Gallery app alternative. It allows you to edit a variety of photos features, including soft focus, saturation, tint, cropping, and color effects. You can upload photos to a free Photoshop.com account (you'll be prompted to create account if you don't have one already). Once your photos have been uploaded, you can share and edit them from your Photoshop.com account.
The icon templates are provided in Adobe Photoshop and Adobe Illustrator file formats, which preserves the layers and design treatments we used when creating the standard icons for the Android platform. You can load the template files into any compatible image-editing program, although your ability to work directly with the layers and treatments may vary based on the program you are using.
In order to use this Bitmap as the source for our image editing experiments, we need to be able to draw this Bitmap onto the screen with the effects applied. Additionally, it would be great to draw it to an object that we can use to save the resulting image from. It makes sense that we'll want to create an empty Bitmap object with the same dimensions as this one and use that as the destination for our altered Bitmap.
Additional terms for specific Google APIs Use of the Android Maps API is subject to further Terms of Service (specifically use of the following packages com.google.android.maps and com.android.location.Geocoder).You must agree to these additional terms before using those specific APIs and always include the Google Maps copyright notice provided. Use of Google Data APIs (Google Apps such as Gmail, Blogger, Google Calendar, Google Finance Portfolio Data, Picasa,YouTube, and so on) is limited to access that the user has explicitly granted permission to your application by accepted permissions provided by the developer during installation time.
If you have a Picasa account associated with a Google Account that you've added to your phone, and if you have configured it to sync with Picasa, Gallery also presents your Picasa web albums. See Configuring account sync and display options on page 105. If you have a great many pictures or videos on your SD card or in Picasa web albums, it may take Gallery a few minutes when you open it to discover and organize them. A Picasa web album.

Sending a multimedia file directly from the file you want to send is easy, too. Navigate to the file you want to send, press the Menu key, and select Share. A Share Picture Via menu appears, as shown in Figure 3.7. You should see options to share via Google Mail and Messaging, but if you have third-party applications (such as MySpace and Picasa) installed, you might also have options for sharing via those services. Chapter 9, Adding Applications to Your Device, covers adding third-party applications to your device, if you want to learn more about those options. Messaging MySpace Q P Picasa
Buttons on the right side of the screen provide quick ways to delete the image to share it via Bluetooth, email, text message, Picasa, or any social networking app installed on your phone and to set the image as your main system wallpaper or as an icon for someone in There's no default Google app for image editing in Android, but in the Android Market you'll find plenty of options for manipulating your pictures. Among the most advanced utilities is Adobe's free Photoshop Express app. As you'd expect, it's a far cry from the full desktop version of Photoshop, but the app makes it easy to perform essential operations such as cropping and colour correction and blurring of your images. Another useful option is the PicSay Photo Editor. This free app includes tools for colour-correcting images and for adding visual effects, graphics, and word balloons. PicSay Pro ( 1.99) adds a bevy of additional photo-editing features, including painting tools, functions to cut out and paste parts of...
You can get photos from your phone to your computer in many different ways. The method you use depends on the bandwidth you have available, your privacy concerns with the photos, and your personal style. You can e-mail photos to yourself or upload them to Picasa and download them to your desktop from the Web. This may present privacy issues if the photos are sensitive, and it may just take too long if you've taken a lot of photos.
PicSay is probably the best known of several photo-editing apps that allow you to make artistic and novel changes to photos before uploading them, as shown in Figure 9-13. PicSay comes in a free trial version and a paid app (about 4.00 as I write this). Google Checkout will convert the currency if you buy the app through the Android Market. The trial version of PicSay has an older version of the interface than the for-pay version, and limits the size of pictures. The pro version also offers more editing options. Similar photo-editing apps include Pic Paint and Camera Illusion.
Picasa is the default option for web albums, but it certainly isn't the only option. You can share photos using Gmail, Email, and MMS messaging, or using a paired Bluetooth device for Bluetooth-capable phones. On many phones, Facebook sharing is also included by default.
EXIF, which stands for exchangeable image file format, is a standard way of saving metadata within an image file. Many digital cameras and desktop applications support the use of EXIF data. Since EXIF data is actually a part of the file, it shouldn't get lost in the transfer of the file from one place to another. For instance, when copying a file from the SD card of the Android device to a home computer, this data would remain intact. If you open the file in an application such as iPhoto, the data will be present.

When developing an application for the desktop, such as Microsoft Word or Adobe PhotoShop, application developers create their core application in a language such as C++ and share that core code across platforms, but then use platform-specific APIs to access the filesystem and develop the user interface. In the 1990s, a number of cross-platform desktop frameworks emerged, making it easier for companies to develop a single codebase that they could compile for each target platform (typically, just Mac and Windows). For mobile development, this is a bigger challenge.
The Gallery app is built into Android phones. In earlier versions of Android, the graphics weren't quite as fancy, but the concept was the same. You see a visual representation of pictures you have stored both on your phone and through Google's Picasa Web Albums. Launch the Gallery app to browse your photos. Photos in the gallery can either come from your phone's storage or from Picasa. You'll see an icon to indicate the source, including folders, the camera folder, and Picasa albums. In Figure 9-7, all the pictures on the screen came from Picasa, as indicated by the white Picasa logo on the corner of each album. NOTE You can upload or delete multiple photos at once through the gallery by viewing an album and pressing the Menu button twice. Gray check marks will appear on each photo or video. Select multiple items by pressing each one. You can then mass-delete them with the Delete button, or upload them to Picasa or YouTube using the Share button.
If you prefer not to use Picasa for your online photo albums, you can use Photobucket, Flickr, or Facebook, so long as you have a compatible app installed. You can also share photos using Bump, an app that allows you to exchange contact info by physically bumping the phone of another user. Bump was previously an iPhone-only app, but it is now cross-platform compatible with Android users.
Default Android settings give you a few options for editing videos, such as cropping or rotating the picture, and you can adjust the white balance for certain lighting conditions. But what if you want to add an effect after you've already taken the photo or edit out red eye Fear not, there are tons of apps that allow you to edit photos directly from your phone. Nothing offers the same quality you'd get from a desktop photo-editing program, but you're using this with a phone camera, not the latest SLR.
