问题 I've just moved to a macbook pro retina with Mavericks and have started getting these warning messages in my rspec output: webkit_server[55708:507] CoreText performance note: Client called CTFontCreateWithName() using name "Arial" and got font with PostScript name "ArialMT".

问题 When showing images from python/tkinter, using code such as: self.label = tk.Label(self.root, image=image) self.label.pack() the image appears pixelated on a MBP retina, i.e. pixel-doubled in each axis. Is there a way to persuade tkinter to show the image at 'native' resolution? If not, what other solutions are available to show the image? Of course the image can be saved a viewed elsewhere but I am after a GUI option. 回答1: If you use the Cocoa version of Tk (for example the ActiveState

问题 I have a set of images with @2x for retina display detection. This works fine on most images, however 1 image is elongated. This image was added to an UIImageView in Interface Builder. I know the names are the same (aside from the @2x part) and the files are both the same type (PNG). What else could be causing this issue? 回答1: You will need to manually set the frame of the UIImageView. 来源： https://stackoverflow.com/questions/4442401/ios-2x-elongated-images

问题 I’m having a lot of problems trying to draw body shapes on my sprites. I tried a lot of combinations but I’m not able to make it work on retina display.

I read several posts and I don’t know if PTM stands for “ Point To Meter ” or “ Pixel To Meter ”. ¿Which column is the right one? B. Physics I want do draw a

问题 I'm trying to emulate Xcode's toolbar controls to show/hide the Navigator and Inspector: ...but without the bottom pane (only left and right: two segments) I screen-captured the icons from Xcode's UI and traced them in an image editing application. The resources for the left pane are: @1x: (20x20 @72 dpi) @2x: (40x40 @72 dpi, although using 20x20 @144 dpi seems to make no difference) The right-pane counterparts are identical, but flipped horizontally. All rhe resources are stored in the asset

问题 I have a very strange problem in my app which only happen on Retina display and not simulator . I developped a set of applications with embedded openstreetmaps tiles (pieces of map). In each app, I have a lot of pieces of map (256px/256px) that I display in a UIScrollView. It works perfectly on non-retina devices and on retina simulator . The problem : each tile appear with the last row of pixel in a randow color (most time it's black) To illustrate, I made to screenshot of the same place,

问题 I'm currently working on enabling support for retina display for my game. In the game, we have a feature that the user can take screenshot. We are using these part of code we found online a while ago and it's working fine when we are not supporting retina display: CCDirector* director = [CCDirector sharedDirector]; CGSize size = [director winSizeInPixels]; //Create buffer for pixels GLuint bufferLength = size.width * size.height * 4; GLubyte* buffer = (GLubyte*)malloc(bufferLength); //Read

问题 I understand that i can't adapt GLPainter example from apple to retina due to a bug mentioned here: Problems displaying full-screen CAEAGLLayer on Retina iPad Any one knows a good starting point to creating an Open-GL basic painter with brushes, that will work on Retina? or - creating an openGL painter without CAEAGLLayer 回答1: I think that the starting point can still be GLPaint , only you need to set to NO hte value of kEAGLDrawablePropertyRetainedBacking and change the way you draw in your

问题 I'm using cocos2D and TexturePacker. My game is working correctly with iOS < 6. Since I upgraded to iOS 6, my images are displayed 4 times bigger in retina.
