Image Size and Resolution
The coordinate system iOS uses to place content onscreen is based on measurements in points, which map to pixels in the display. A standard-resolution display has a 1:1 pixel density (or @1x), where one pixel is equal to one point. High-resolution displays have a higher pixel density, offering a scale factor of 2.0 or 3.0 (referred to as @2x and @3x). As a result, high-resolution displays demand images with more pixels.

Are there downsides for using only @x3 images, showing the same images on both @x2 devices (iphone 4, 4s, 5, 5s, 6) and @x3 devices (6+) i guess it means resizing on the fly. Or should i use @x1. Similarly tag is used to define an area within an image and take one of the following three shapes: Rectangle. Rectangle is defined with the shape attribute “rect” and accepts the coordinates in the format “x1,y1,x2,y2” where (x1,y1) are the upper left corner of the rectangle and (x2,y2) are the lower right corner of the rectangle. Video Pro X is the only video editing software that makes professional video production accessible for everyone. With intuitive editing tools and workflows, getting started with Video Pro X is easier than with any other professional video editor.
For example, suppose you have a standard resolution (@1x) image that's 100px × 100px. The @2x version of this image would be 200px × 200px, and the @3x version would be 300px × 300px.
Convert JPG/PNG to Webp, make your web faster! WebP file format is a new image format released by Google that stores both lossy and lossless compression formats in high-quality. An app should specify several different icons of different dimensions to suit different screen sizes and different situations. You can save valuable time by using Makeappicon.com to generate app icons of all dimensions you need for submitting your apps to Apple in one click, no matter it’s built for iOS 7, iOS 8 and iOS 9, and focus on coding.
Supply high-resolution images for all artwork in your app, for all devices your app supports. Depending on the device, you accomplish this by multiplying the number of pixels in each image by a specific scale factor.

Designing High-Resolution Artwork
Use an 8px-by-8px grid. A grid keeps lines sharp and ensures that content is as crisp as possible at all sizes, requiring less retouching and sharpening. Snap the image boundaries to the grid to minimize half pixels and blurry details that can occur when scaling down.
Produce artwork in the appropriate format. In general, use de-interlaced PNG files for bitmap/raster artwork. PNG supports transparency and, because it's lossless, compression artifacts don't blur important details or alter colors. It's a good choice for intricate artwork that requires effects like shading, textures, and highlights. Use JPEG for photos. Its compression algorithm usually produces smaller sizes than lossless formats and artifacts are harder to discern in photos. Photo-realistic app icons, however, look best as PNGs. Use PDF for glyphs and other flat, vector artwork that requires high-resolution scaling.
Use the 8-bit color palette for PNG graphics that don’t require full 24-bit color. Using an 8-bit color palette reduces file size without reducing image quality. This palette is not appropriate for photos.
Optimize JPEG files to find a balance between size and quality. Most JPEG files can be compressed without noticeable degradation of the resulting image. Even a small amount of compression can save significant disk space. Experiment with compression settings on each image to find the optimal value that yields an acceptable result.
Provide alternative text labels for images and icons. Alternative text labels aren’t visible onscreen, but they let VoiceOver audibly describe what's onscreen, making navigation easier for people with visual impairments.
According to Apple’s iOS Human Interface Guidelines, every app must provide an icon to be displayed on a device’s Homescreen and in the App Store. An app should specify several different icons of different dimensions to suit different screen sizes and different situations.

Apps distributed via ad-hoc distribution may also include a 512 x 512 pixel version of their icon in the CFBundleIconskey. The name of this file must be iTunesArtwork (with no file extension). The high resolution version of this icon should be 1024 x 1024 pixels and have the name iTunesArtwork@2x (also without file extension). Do not include this icon in your app bundle if you are not distributing your app via ad-hoc distribution.
