DPI in Retina iPad app design

北战南征 提交于 2019-12-03 01:45:21
I don't know if this belongs in StackOverflow or some other SE site, but here goes. I have a PSD design I have an iOS development team turning into a Retina iPad app. However, this design is made in the default 72 dpi. The development team is now saying the design should be 264 dpi (same as a Retina iPad) -- as well as a 132 dpi version for the non-Retina edition. This confuses me, as I was under the impression that dpi just represents how many pixels go into an inch of output, and therefore would only matter in printing. The dpi of an iPad just represents the number of pixels for each inch of

OS X icons size

六眼飞鱼酱① 提交于 2019-12-03 01:43:20
问题 What size should an application icon and menu bar icon for OS X be? I can deal with small resolution displays but what about Retina - does an icon displayed on the menu bar (e.g. 20 x 20 ) will be smaller or blurred on a new MacBook Pro with Retina display? I reckon that the Application icon will be scaled, so if I'll prepare twice larger than regular it should be OK on Retina. I found an excellent guide for iOS development with sizes specification but I can't find similar size specifications

iOS: How do I support Retina Display with CGLayer?

拥有回忆 提交于 2019-12-03 01:04:51
问题 I'm drawing a graph on a CALayer in its delegate method drawLayer:inContext: . Now I want to support Retina Display, as the graph looks blurry on the latest devices. For the parts that I draw directly on the graphics context passed by the CALayer, I could nicely draw in high resolution by setting the CALayer's contentScale property as follows. if ([myLayer respondsToSelector:@selector(setContentsScale:)]) { myLayer.contentsScale = [[UIScreen mainScreen] scale]; } But for the parts that I use

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago . I've seen this news from Apple talking about new iOS app submissions needing to be built for retina devices: https://developer.apple.com/news/?id=3212013b I know that it says that apps and app updates "must be built for iOS devices with Retina display", which is pretty generic and could maybe include the iPad,

Configuring Jupyter notebooks for inline Retina Matplotlib figures

落花浮王杯 提交于 2019-12-02 19:18:09
I want the effect of import numpy as np import matplotlib.pyplot as plt %matplotlib inline %config InlineBackend.figure_format='retina' at the launch of all my Jupyter notebooks, but I can't figure out what the current approach is for accomplishing this. There are many answers here and elsewhere, but none that I can find seem to be up to date. How do I accomplish the above in the current versions of Jupyter notebooks (but not IPython generally!): what settings should I apply where is the configuration file I should put them in? I've tried c.InteractiveShellApp.matplotlib = "inline" c

Why doesn't icon composer 2.4 support the 1024x1024 size icon any more?

核能气质少年 提交于 2019-12-02 16:26:39
The icon composer 2.2 in Xcode 4.3.3 supports the icns of 1024x1024. However, for icon composer 2.4, it doesn't support that any more. This is ironic, since Apple pushes for the retina display mbp and requires the newly submitted app to use 1024x1024 icon, but the icon composer doesn't support it any more. Is there any alternative or newly introduced solution by Apple for creating the icon of the size 1024x1024? I really don't understand why Apple is doing this. Thanks! Nick Haddad Icon Composer 2.4 doesn't support 1024x1024 size icons anymore because the workflow for creating application

Box2d custom polygon and sprites mis-matching

问题 I am using the Physics Editor for creating the Polygon in Box2d. It generates the Polygon and works fine in the non-retina display but doesn't work in the retina display..... I have attached the screen shot for both of the displays.Now when comes to retina display the polygon is not set over the car here's the image for that Here's my code which I am using in the Project CCSprite *car = [CCSprite spriteWithFile:@"opp_car.png"]; [car setPosition:ccp(wSize.width/2+50,wSize.height/2-120)]; [self

No mention of retina iPad whatsoever. So, will it really be mandatory for submitted iPad apps to be compatible with the New iPad

iPad retina images - Why use two different image sizes?

时间秒杀一切 提交于 2019-12-02 09:45:58
问题 For iPad Retina (or iPhone Retina as well), why do we need to have two types of image sizes and add a suffix like @2x for the retina version? Can't we just have one type of retina resolution images and for devices that do not have retina display, let the device handle resizing the image to smaller (non-retina) size? 回答1: Resizing takes time and memory. And resizing while retaining sharpness is hard to do. Which algorithm do you use? Bicubic or bilinear? "But this icon looks better when
