In an app I am working on that goes on an iPad air, I have the camera facing the user turn on and take a live video feed of the user is placed in an outlet called ImagePreviewOutlet. It works but the aspect ratio is too narrow leaving 2 white spaces on the left and right of th...
大多数显示设备(例如,计算机监视器)使用方形像素,且其“像素纵横比”(Pixel Aspect Ratio)为 1。但是,也有一些设备使用非方形像素(例如,NTSC 视频的“像素纵横比”(Pixel Aspect Ratio)为 0.9)。 若要设定像素纵横比,请参见设定分辨率和像素纵横比。 ,...
aspect-square: It replaces CSS aspect-ratio: 1 / 1 property ensuring that the element would remain square-shaped while adapting different screen sizes. aspect-video: It replaces CSS aspect-ratio: 16 / 9 property ensures applying aspect ratio 16/9 for an embedded video element in a responsi...
Hi all, based on my comments in the other issue I have begun brainstorming and writing a polyfill for what an aspect-ratio property might look like. I currently have the logic figured out, and a regex that can extract this custom property from formatted CSS, I think I'm close to a wo...

It's trivial to move and scale a UIImageView in a number of different ways. -- Update: device scaling is now properly handled, thanks to budidino for that! You should resize the image, so that it will have the width of your image view, but by keeping its aspect ratio. After that,...
High aspect ratio chemically and spectrally sensitized tabular grain silver halide emulsions, photographic elements incorporating these emulsions, and processes for the use of the photographic elements are disclosed. In the tabular grain emulsions the silver halide grains having a thickness of less than ...
Aspect ratiois a fancy term for “proportion,” or the ratio of width to height. for example 4:3 for acomputerscreen. For instance, if a direction in a software manual tells you to “hold down the Shift key while you resize a graphic in order to maintain the aspect ratio,” it simpl...
Theory suggests that stretching the structures post-formation is one of the only ways to increase the aspect ratio of the pillars. We developed a tool to physically stretch these structures to increase their aspect ratio from ∼0.1 to ∼0.5. The capabilities and limits of this stretching ...
