You can see how the colored regions map to the example grid shown above. This is a simple example slot machine games win real money, but the user can create multiple regions in the same image like so: Defining the content area gives the user the ability to assist Android in providing the proper location where source content (text, other images, etc.) are placed when this image is a background or other content wrapper image. Think of the standard Button as an example. When a user defines android:text (of android:src on an ImageButton), this is the button content. That content is laid out inside of the content area that was defined in the button background image (a 9-patch, by the way). Creating 9 Patch Images What is a 9 Patch Image? For more information roulette online 411, the official Android documentation on 9-patch can be found here and a really good tutorial can be found here. The border is used to indicate which area(s) of the image can be stretched and optionally which area(s) of the image are fillable (i.e. can be overlaid with text when the image is used as a background image for an Android View object, such as a Button ). The black pixels in the top and left borders ensure that only the blue background portion of the image will be stretched when the available display area is larger than the image size. The center logo and the outer red box will remain static. What is a 9-patch image? Creating a 9-patch splash screen image If for some reason you would rather use your favorite image editor, remember the following 9-patch image constraints: A very handy, but little advertised feature introduced in MAF 2.2.0 is the ability to use 9-patch splash screen images for Android. Today I discovered nine patch images. The documentation linked to in the other answers is ok I suppose online slots real money canada international phone, but they really lack in examples. This little tutorial has some great examples at the end that answer the second part of your question, explaining how the scaling works - not just for buttons - but also frames. The nine patch can specify non-contiguous areas to scale. Make sure you only have 1 image under the main /drawable folder (not a version for each dpi folder) Reference the drawable with the name but don't include .9.png (auto-complete in eclipse will take care of this) Just to flesh out the the answers to the first part of your question, the SDK ships with "draw9patch" (in the tools folder) which is a simple editor. Here is another downloadable one which is good online slots real money canada mosque, and it has a simple but clever default image. Most of the examples talk about creating a 9-patch image, but implementation details are usually left at a high level. A NinePatchDrawable graphic is a stretchable bitmap image, which Android will automatically resize to accommodate the contents of the View in which you have placed it as the background. An example use of a NinePatch is the backgrounds used by standard Android buttons — buttons must stretch to accommodate strings of various lengths. Make sure the image and layout that contains it are using: It's important to note that 9-patch images don't scale down - they only scale up. So it's best to start as small as possible. Basically, 9-patch uses png transparency to do an advanced form of 9-slice or scale9. The guides are straight, 1-pixel black lines drawn on the edge of your image that define the scaling and fill of your image. By naming your image file name.9.png. Android will recognize the 9.png format and use the black guides to scale and fill your bitmaps. Your guides must be solid black (#000000). Even a slight difference in color (#000001) or alpha will cause it to fail and stretch normally. This failure won't be obvious either* casino yellow head, it fails silently! Yes. Really. Now you know. The black guide lines are cut-off/removed from your image - they won't show in the app. Guides must only be one pixel wide, so if you want a 48x48 button, your png will actually be 50x50. Anything thicker than one pixel will remain part of your image. (My examples have 4-pixel wide guides for better visibility. They should really be only 1-pixel). Also gambling advent chronicle kaiji, you can leave out portions in the middle of the scale line. So for example, if you have a button with a sharp glossy edge across the middle, you can leave out a few pixels in the middle of the LEFT guide. The center horizontal axis of your image won't scale, just the parts above and below it, so your sharp gloss won't get anti-aliased or fuzzy. The image inside the square will not be distorted on any screen size, but it may be stretched. Using the highest resolution files possible. I recommend you also generate these for a landscape mode as well. Once you have defined your aspect ratio locked area, download the zip. It will contain all the resolutions with your <imagename>.9.png. Splashscreen images for Xamarin Android can be tricky to create, as you must account for portrait and landscape modes in a large array of possible screen resolutions and density’s. Fortunately, Android has a solution for this called a 9-Patch image. As you know – there is a standard WYSIWYG editor for nine-patch (.9.png) files within the dev tools for Android developers. Once i have started integrating nine-patch file format support into Swing components i noticed that its really inconvenient to use. So i got an idea to create my own small nine-patch file editor… 1. Possibility to work with multiple nine-patch images at the same time 1. Comfortable WYSIWYG editor – easily add, move, resize and remove patches Thanks buddy. It’s the best and the easyest tool I’d found. 1) Whether the image is or is not a 9patch should be determined from file extension *.9.png. I encounter a problem when I tried to create a 9patch from image which already had black outline – it was processed as if it was already a 9patch, destroing image outline. Thanks for the feedback! 2) Some cropping capabilites. I’m looking for a feature that would allow me to delete (or add) rows/columns from image – to resize big stretchable areas. 2. I will allow cropping image like in all other graphic editors (by selecting area you want to keep) but will also allow to remove selected columns/rows from the image (basically – the same way patches could be added now paypal job openings, but cropping will be done with another tool). Or you meant the downscaling? That is something that could actually be done online gambling canada viagra, but I’m not sure how exactly should it work. 3) Some image scaling capabilities – it would be great to have some tool that would be able to scale 9patch in a way that keeps the border 1px large and up-/downscales the rest of the image.
