retina-display

The next update of my iPhone app will be targeted for iOS7 only. A couple of questions? Does this mean I can delete all the non-retina images from my app? If I have only retina images left do I still need to mark them @2x? Does Apple keep older iOS versions of my app on the store so those running older versions of iOS who have bought or want to buy can still access it? Any help would be most appreciated. Yes you still need to have the @2x at the end. Yes you can drop all the non-retina images but could affect performance as even the newer devices will use some none-retina images but the main

I've got a Java desktop app that works, amongst other, on OS X. Now the new MacBook Pro has a retina display and I'm concerned: how is it going to work regarding Swing? What about when a Java app uses both Swing components and some bitmap graphics (like custom icons / ImageIcon)? Shall all desktop Java apps be automatically resized (for example by quadrupling every pixel) or am I going to need to create two versions of my icons set (for example one with 24x24 icons and the other with 96x96 icons) and somehow determine that the app is running on a retina display? Use IconLoader library. It

In my iPad app, I am rendering to an offscreen bitmap, and then drawing the bitmap to the screen. (This is because I want to re-use existing bitmap rendering code.) On the iPad 2, this works like a charm, but on the new iPad with Retina display, drawing the bitmap is really slow, even though its resolution is still the same. To draw the bitmap, we use the regular Quartz 2D functions: CGImageCreate with a data provider created by CGDataProviderCreateWithData , 32-bit RGBA format with kCGImageAlphaNoneSkipLast . In the UIView that displays the bitmap, in drawRect: , we use CGContextDrawImage to

I have an application that breaks in HiDPI mode unless I chose "get Info" in finder and there tick the "open in low resolution" checkbox. Fixing the application is not an option as it was made using authoring software that is no longer really actively maintained by its vendor. Now here is the thing: When I take the application, put it on the desktop, zip it and afterwards set the "open in low resolution" checkbox to true, delete the application and unzip the original one the checkbox stays checked. So wherever OS X stores the property "open in low resolution" it's not along with the file. That

how to detect, in a cross-browser compatible way , the pixel density of the device visiting a webpage so that one can either serve standard or highres images without forcing doubled images to any device? Is there any javascript library that automates this? Why setting for Retina iPhone 4s, iPhone 5, iPad3, iPad4, Macbook 15", Macbook 13" all use Retina display. Android also support high resolution display, as well as Windows 8(Lumia 920) as mentioned by @JamWaffles. Adding high resolution support is good for user experience but it definitely add load for developer, as well as bandwidth for

I'm designing a responsive site that will look different on mobile devices. I have three separate media queries in my css plus a query for retina display(s). /** 768PX IPAD PORTRAIT **/ @media screen and (max-width: 768px) {} /** 480PX IPHONE LANDSCAPE **/ @media screen and (max-width: 480px) {} /** 320PX PORTRAIT **/ @media screen and (max-width: 320px) {} /** RETINA IMAGES **/ @media all and (-webkit-min-device-pixel-ratio: 2) {} When iPad is in portrait mode, it will get the mobile version, but when it's in landscape mode it will get the regular version of the site. My problem is this, now

I am using the following code to perform some manipulations on the image that I loaded, but I find that the display becomes blurry when it is on the retina display - (UIImage*)createImageSection:(UIImage*)image section:(CGRect)section { float originalWidth = image.size.width ; float originalHeight = image.size.height ; int w = originalWidth * section.size.width; int h = originalHeight * section.size.height; CGContextRef ctx = CGBitmapContextCreate(nil, w, h, 8, w * 8,CGImageGetColorSpace([image CGImage]), kCGImageAlphaPremultipliedLast); CGContextClearRect(ctx, CGRectMake(0, 0, originalWidth *
