Although most image formats support only a single image, formats such as TIFF can store multiple images. Important: While NSImage objects support multiple representations, CGImage does not. The window server composites drawing operations to an offscreen buffer called the backing store. Simple questions: What is an AMOLED screen? The system must magnify the contents of the backing store to fill the display. Apps that aren’t Cocoa apps have this checkbox selected and unavailable (dimmed). For example, is it possible to use a 720p TV to watch a 1080p video? An interlaced display paints all the odd lines first, then all the even lines. For that reason, NSImage is the class of choice for supporting images on high-resolution displays. A user can choose to run a Cocoa app in magnified mode if the app has usability issues related to high resolution. The virtual screen decouples the physical pixels drawn in device space from the user space your app draws to, so you don’t need to concern yourself with the characteristics of the display on which your app runs. In framework-scaled mode, the application framework automatically adjusts the drawing size to ensure sharp graphics whether the display is standard or high resolution. What does OLED mean? 4:3 aspect ratio resolutions: 640×480, 800×600, 960×720, 1024×768, 1280×960, 1400×1050, 1440×1080, 1600×1200, 1856×1392, 1920×1440, and 2048×1536. However, any drawing code that uses memory you create, such as Quartz bitmaps, will require you to manage the content. High Resolution Explained: Features and Benefits. The controls appear the same size to the user regardless of the backing store size, but on a high-resolution display, the controls look sharper due to the density of the backing pixels. Floating-point advancements result in more precise layout, as shown in Figure 1-4, and allows for kerning and ligatures for smaller font sizes.

The user interface is sized as you expect, with no additional detail, and might look slightly blurry as a result. A “p” stands for progressive, and an “i” stands for interlaced. EGA (Enhanced Graphics Adapter): Following CGA, an adapter that could display 16 colors with a screen resolution of 640x350 pixels. Motion picture aspect ratio changed much more quickly to a wider screen, which meant that, when movies were shown on TV, they had to be cropped or the image had to be manipulated in other ways to fit the TV screen. The backing store of a window is owned by the display on which the window is drawn. The aspect ratio is not used to describe screens (or any rectangular shapes) in portrait mode. Let’s look at what today’s terminology is, and what it means: The term “resolution” is not correct when it is used to refer to the number of pixels on a screen. As monitor quality improved, Windows began offering a few more built-in options, but the burden was still mostly on the graphics card manufacturers, especially if you wanted a really high-resolution display. OS X refers to screen size in points, not pixels. The fact that the backing scale factor is always a whole number is another key feature of high resolution. Typical printing PPI values range from 150 to 300 PPI, although some high-end magazines may require images that are 1200 PPI. In all cases, this value will be either 1.0 or 2.0, depending on the resolution of the underlying device. In framework-scaled mode, the backing store has the same number of pixels as the display. Free for commercial use High Quality Images The system scales the contents using nearest-neighbor interpolation to draw the content on a high-resolution display. Since the beginning, the resolution has been described (accurately or not) by the number of pixels arranged horizontally and vertically on a monitor. 1440p = 2560 x 1440 – is commonly known as QHD or Quad HD resolution, and it is typically seen on gaming monitors and on high-end smartphones.

See high resolution stock video clips. 2160p is called 4K because the width is close to 4000 pixels. In magnified mode (shown in Figure 1-5), the backing store has one-fourth the number of pixels as a high-resolution display (half the width and height of the display). An image representation object (NSImageRep) represents an image at a specific user size and pixel density, using a specific color space, and in a specific data format. 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). An increase in pixel density means that drawing is more precise, resulting in sharper text, extremely detailed photos, and a more defined user interface. For example, a resolution of 1920×1080 pixels is the same as 1080×1920 pixels; it is just that the orientation differs. The higher you set the resolution, the smaller the images on the screen are, and there comes a point at which the text on the screen becomes so small it is not readable. When it comes time to display the image in your app, NSImage chooses the smallest image representation that has more pixels than the destination. A point is one unit in user space, prior to any transformations on the space. How do I get a photo that is high resolution? Eroare.

In other words, you could say that an aspect ratio of 16×9 is the same as 9×16, but the latter is not an accepted form of referring to aspect ratio. Most Cocoa apps have this checkbox available, but not selected. All apps that are not Cocoa apps run in magnified mode. How well an existing app runs in high resolution depends on the frameworks and graphics resources it uses. The system frameworks are optimized and updated to perform the work needed to map user space to device space. Capable of producing 16 colors at 160x200 pixels. If the “Open in Low Resolution” checkbox is selected by default for your app—whether the checkbox is available (dimmed) or not—you can change the default by: Fixing all bugs related to high resolution. Background: The characteristics of plaque that ultimately lead to different subcortical infarctions remain unclear. 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. For example, if you want to watch a video with a 4K resolution on a 720p screen, that video is shown at 720p resolution, because that is all that your screen can offer. Most of the time, OS X automates dynamic resolution changes, seamlessly switching content from standard to high resolution. “Resolution” is technically the number of pixels per unit of area, rather than the total number of pixels. The backing scale factor is not global—it is a property of the object (layer, view, window) and is influenced by the display on which it is placed. The most recent versions of Windows set the framerate at 60 Hertz or 60 cycles per second, and LED screens do not flicker. Nowadays, nearly all computer monitors and TVs are only available in widescreen, and TV broadcasts and web pages have adapted to match. However, this also means that there are a lot more options to choose from, with something to suit almost everyone’s preferences. But after you provide those versions, AppKit will manage loading the appropriate version for the resolution. Let’s get started: The color graphics technology was first developed by IBM. Although a 4:3 TV’s display can be adjusted to show black bars at the top and bottom of the screen, while a widescreen movie or show is being displayed, this does not make sense with a monitor, so Windows does not even offer you the widescreen display as a choice. The display resolution or display modes of a digital television, computer monitor or display device is the number of distinct pixels in each dimension that can be displayed. In your own drawing code you will use points most of the time, but there are instances when you might need to know how points are mapped to pixels.
