retina-display

This is probably linked to another unsolved mystery of mine. I'm drawing Orthographic 2d on iPhone, using real device and simulator. I'm trying to color my pixels a given color depending on how far they are from arbitrary point in pixelspace of 'A', which I pass in (hard code). I'm doing everything in Retina 960x640 resolution. I calculate distance from A to gl_FragCoord , and I color based on leaping between 2 colors with the 'max' being 300px distance. When on simulator (with retina display) I need to give a center point of "460" pixels for screen midpoint X.. Y I give 160px, and I look for

is there any way I can change the resolution of Android Studio? recently I migrate my Android Studio from rMBP 13' to rMBP 15' and the text is blurry. I tried to change its resolution hoping to fix it but found no way to do. do you guys met with this before? There's a known issue with IntelliJ and Android Studio on MacOS that only Apple's JDK does proper subpixel antialiasing in its rendering. If you're using an Oracle JDK, then the rendering is not as good. Unfortunately, this means that the only Java version with good rendering is 1.6; Oracle picked up MacOS support for JDK 1.7 and 1.8. The

When testing on my iPad 3, [[UIScreen mainScreen] scale] == 1.0 My understanding is that this should be 2.0. I am using the iOS 5.1 SDK with Xcode 4.2 on Snow Leopard, which I understand is not an "officially supported" configuration. However, I can't imagine why that would affect what is happening purely on the device. (I can imagine all sorts of ways it would break the simulator.) Before XCode version 4.3, [UIScreen scale] will return 1.0 for an iPad 3. Updating to 4.3 will enable the correct value of 2.0 being returned. That's because the screen is not scaled. You can get the ratio like

Just that question I want to detect the retina display in my MonoTouch app. Thanks. poupou There are already answers for ObjectiveC but here's a C# version: bool retina = (UIScreen.MainScreen.Scale > 1.0); That will work for the newer iPhone and iPod Touch and I suspect (will know in less than two weeks) for the new iPad. Jason's approach will work too and can be attractive if you need to know several hardware related features (e.g. retina + camera). 来源： https://stackoverflow.com/questions/9611784/how-to-detect-the-retina-display-in-monotouch

I have a question about updating my app's graphics for the retina display of the iPhone 4. I am keeping each view's resolution to 480 x 320 Points. So I was wondering: suppose I have a 100 x 50 UIImageView. It's better for my actual image I am going to load to be 200 x 100 pixels @ 163 ppi or 100 x 50 pixels @ 326 ppi? Is it the same thing in terms of 'lightness'? which is the preferred way? Thanks, you're awesome Lorenzo 1) Define your UIImageView to be 100 x 50 pixels as you describe it above. 2) Have one image file that is 100x50 pixels "MyImage", and a second image file that is 200x100

On iPhone5 [[UISCreen mainScreen] bounds].size comes back as 320x480. Why. In all the posts I'm reading, people are saying that it returns the correct screen size. What is going on here? Am I missing something in the .plist file or something? BTW I am hand coding the GUI, so there is no XIB. Unless your app includes a Default-568h.png in it's bundle, it will run inside a 480 point high legacy screen sandbox on the iPhone 5, and can't draw or see any dimensions outside that sandbox. Note that including this Default-568h.png is only allowed when building an app using Xcode 4.5 and the iOS 6 SDK

I'm creating an HTML5 canvas game for iPhone. I would like to support both retina and non-retina displays. My question is, how do I support both retina and non-retina displays? I.E., what is the general implementation for doing this? Do I write the game using the iPhone dimension and then add retina support? Or do I create the game retina size and add non-retina support? Is it best to have two images, one retina one non-retina? or just scale the retina image down? Do I have separate canvas sizes for retina and non-retina? Do I need to scale the mouse input? Basically, I have no idea on the

I am using an iMac to do OS X App Development, but my iMac is not a retina display. Is this possible to let me simulate the result on retina display Mac? Thanks. I used Quartz Debug to get a HiDPI entry in Displays. This was pre-Mavericks, so I'm not sure if that's still the recommended way to do it. The answers here mention a couple different ways . You may also need to hold Option while clicking on "Scaled" in Displays . 来源： https://stackoverflow.com/questions/30872623/is-this-possible-to-simulate-an-retina-display-os-x-on-non-retina-display-mac
