Large‐scale gravity wave characteristics simulated with a high‐resolution global thermosphere‐ionosphere model L. C. Gardner1 and R. W. Schunk1 Received 30 April 2010; revised 18 February 2011; accepted 10 March 2011; published 2 June 2011. For that reason, NSImage is the class of choice for supporting images on high-resolution displays. before you send us your feedback. See Adjust Font Settings to Ensure Document Compatibility. A CGImageRef is limited to one image at one resolution. On a larger monitor it is possible to push the resolution very high indeed, but if that monitor’s pixel density is not up to par, you won’t get the maximum possible resolution before the image becomes unreadable. Most of your existing drawing code will work without modification because the window server automatically accounts for the size of the backing store for a window graphics context. 720p = 1280 x 720 – is usually known as HD or “HD Ready” resolution, 1080p = 1920 x 1080 – is usually known as FHD or “Full HD” resolution. That is covered by another metric, called PPI (Pixels Per Inch). A user can choose to run a Cocoa app in magnified mode if the app has usability issues related to high resolution. 1440p is four times the resolution of 720p HD or “HD ready.” To make things even more confusing, many premium smartphones feature a so-called 2960×1440 Quad HD+ resolution, which still fits into 1440p. Regardless of what your screen resolution is, you can watch any video on it, no matter the video’s resolution (higher or lower). Then, set the key’s value to NO (Boolean value).

There are some cases for which your app will need to take action when a change in resolution occurs (see Handle Dynamic Changes in Window Resolution Only When You Must). Tip: Make sure your Cocoa app has a Principal class setting. If your app is optimized for high resolution, you can request that the “Open in Low Resolution” checkbox is not displayed by adding the NSHighResolutionMagnifyAllowed key to the Info.plist for your app. But after you provide those versions, AppKit will manage loading the appropriate version for the resolution. Internal waves are extremely important in the atmosphere, and past global studies have looked at the impacts of gravity waves on the thermosphere using gravity wave parameterizations. Echod Graphics high resolution Adhesive Vinyl adhere to almost any smooth surface, and will stand the test of time. The choices available were determined by the capability of the video card, and they differed from manufacturer to manufacturer. To change the resolution to 300 ppi, uncheck the Resample box to lock the Width, Height, and Resolution, then change the Resolution to 300 ppi, like this: Now you can see how big the image is for printing. larry.gardner@usu.edu; Center for Atmospheric and Space Sciences, Utah State University, Logan, Utah, USA.

Your app draws to a view using points in user space. Although most image formats support only a single image, formats such as TIFF can store multiple images. What does OLED mean? In other words, it offers four times the pixels of 1080p FHD or “Full HD.”. This is called downsampling. When used in reference to high resolution in OS X, points in user space do not have any relation to measurements in the physical world. The number always refers to the number of horizontal lines on the display. applications are the two driving forces in the quest for greater bandwidth. Bitmapped images are magnified for high-resolution display. by Jeanine Davis | Blog, Design tips. You may have seen the screen resolution described as something like 720p, 1080i or 1080p. 3,000+ Vectors, Stock Photos & PSD files.

The window server composites drawing operations to an offscreen buffer called the backing store. Keep in mind: cropping and resampling For those cases, it is possible to obtain the backing scale factor, which tells you the relationship between points and pixels for a particular object (a view, window, or screen). The term aspect ratio was initially used in motion pictures, indicating how wide the picture was in relation to its height. starting with a finished graphic at a low but unknown resolution then making changes and saving it at a higher resolution; making a mash-up of several different graphics, each at different resolutions and saving the result as a high resolution image; converting graphics … From experience, you can't just put one model there, shade it, and expect it to look amazing.
