This positioning allows the points to remain cleanly aligned to the raster grid at higher resolutions, because 2x and 3x are multiples of 1x. When you use resizable vectorized shapes, you might want to position control points at whole values so that they’re cleanly aligned at 1x. Scale and and general, design images at the lowest resolution and scale them up to create high-resolution assets. Use the following values for guidance for additional scale factors, see Layout. As you add each image to your project’s asset catalog, identify its scale factor by appending or to its filename. You accomplish this by multiplying the number of pixels in each image by a specific scale factor.
Supply high-resolution images for all artwork in your app, for every device you support. JPEG files, optimized as necessary, or HEIC filesįlat icons, interface icons, and other flat artwork that requires high-resolution scaling
PNG graphics that don't require full 24-bit color Because of higher pixel densities, high-resolution displays demand images with more pixels.Īs you create different types of images, consider the following recommendations. A 2:1 density (called has a scale factor of 2, and a 3:1 density (called has a scale factor of 3.
High-resolution displays have a higher pixel density, such as 2:1 or 3:1. A standard-resolution display has a 1:1 pixel density (also called where one pixel is equal to one point.
#Perfect layers too mini how to
To make sure your artwork looks great on all devices you support, learn how the system displays content on the screen and how to deliver art at the appropriate scale factors.Īll platforms use a coordinates system based on measurements in points, which map to pixels in the display.
