retina-display

I have an old app and created @2x high res images for it. Now I've incorporated all these into my project, but when I build and run the app on the retina display test device I do not see the high res images. To be sure, I made some of them with strange colors so I know exactly if @2x is used or not. I also tried to clean my build and all targets first. It just seems the device is refusing to use high res images. Must I set a flag in the info.plist? it's a known issue with imageWithContentsOfFile: . In API docs, it says it should work, in reality it doesn't (didn't work in 4.0.x, not sure about

I wanted to know that how should i proceed to support graphics properly on both retina and non-retina display ? I have a background image of dimension 640 * 920, i think it is for retina display. But i how would i go for supporting non retina display having dimension 320*480 ? How do you structure your graphics resources ? I have group called "Art" having all graphics (right now all for retina display dimension). Will ios automatically scale down my graphics to non - retina display ? I had one more query, like i am dragging one button to a view on some absolute position for retina display,

i have button image of size 560*66 can i put this button image iPhone 4.0 device?and also how will i give aspect ratio this button by using @2x. If you are making a universal app, for both iphone and ipad, then you need to have a naming scheme like this MyIcon.png //ipad MyIcon~iphone.png //low res iphone MyIcon@2x~iphone.png //high res iphone You don't need to have a pixel wise correlation between the ipad and the iphone pictures, but the low res and high res pictures need to be exactly 1:2, ie. if the low res is 50x50 then the high res should be 100x100. There is a bug in 4.0 where you have

The way UIImageView autorotates some images and not others (or autorotates images at all) completely baffles me and I can't find the settings to turn off this autorotate behavior. As a test I created a project using the iOS6 SDK targeted to iPhone 5 with the following steps: I took a photo using my iPhone 4's front facing camera with portrait orientation transferred it to my desktop using DropBox imported it into my project and specified it in StoryBoard as the source for a UIImageView. These are the layout settings for the imageView: Running it in the simulator for the retina3.5 and iPhone 5

Python's matplotlib does not generate Retina display quality LaTeX text by default. Are there settings or add-on package that generate Retina quality output? Are you using 'Agg' mode (standard) to create PNG Graphs? You can create SVG Graphs with Matplot lib which have way better quality using matplotlib.use('svg') tacaswell If you look into texmanager.py you see that it makes the png by a call to dvipng and the function that makes the system call to dvipng has an argument for dpi To get higher resolution TeX on a per-figure basis for existing figures plt.gcf().canvas.renderer.dpi = what_ever

Javascript tells me that my Galaxy S3 has a screen resolution of 720x1280 But the document is reported as 360x567. Is it possible to get the document to more accurately reflect the screen resolution? Initial-scale on the viewport perhaps? I don't seem to be able to manage it! To clarify, I know my device resolution is 720px wide in portrait mode, however when putting an element on a webpage the element fills the width of the page at 360px wide because the device is using 2 hardware pixels for each css pixel. Can I stop the device from doing this? First, why not to use that information most of
