aspect-ratio

问题 There are some questions that are properly similar, but i can't relate it to my specific situation. I have created a responsive thumbnail grid with 4-to-3-to-2 columns structure (in percentages 25%-33,33%-50%). I'm using a fake placeholder image of 500x330px for testing, but i would like to have a fixed thumbnail placeholder (css code?) with a responsive 500x330 ratio and maintain the aspect radio of the images placed in centered (vertical and horizontal) the placeholder thumbnail. In the

问题 I used the JsFiddle at jsfiddle.net/5tzk3/10. I changed it to display the div as square shaped dialog (both horizontally and vertically centered). The result is at jsfiddle.net/5tzk3/548. As you see, centering horizontally was easy, but I could not get it centered vertically. Anyone who knows how to do that with pure CSS? Edited code below: <div class="blind"> <div class="wrapper"> <div class="main"> I'm your div with an aspect-ratio of 1:1! </div> </div> </div> html, body, .blind { height:

问题 I have an app where user can draw a rectangle, and resize it or move it. I'm interested if is possible to some how bind rectangles width and height in some aspect ratio. E.g. if aspect ratio is 1:2 that user can draw only that kinds of rectangles, or if is 1:1 that user can only draw square. EDIT My eventHandler for MOUSE_DRAGGED event looks something like this EventHandler<MouseEvent> onMouseDraggedEventHandler = event -> { if (event.isSecondaryButtonDown()) return; double offsetX = event

问题 Changing UI Image's sprite, preserve aspect ratio is checked but not working. Version: Unity 2019.1.0f2 What happened I updated to the latest software update for Unity which is Unity 2019.1.0f2. Before when it was version 2018.3.12f, the UI Image's sprite changes normally. But now when I have updated it, it doesn't regain its aspect ratio and gets stretched. When the sprite changes on the UI image, the aspect ratio/width and height changes for the image and when you go back to the original

问题 I'm using bokeh 1.0.4 and I would like to generate an image plot in bokeh using match_aspect=True . Here is a example code for illustration: from bokeh.models.ranges import DataRange1d from bokeh.plotting import figure, show import numpy as np arr = np.array([[1,2,3],[4,5,6]]) plot = figure(match_aspect=True) plot.image([arr], x=0, y=0, dw=3, dh=2) show(plot) This is what I get: There is a lot empty space around the data, too much for my application, and I would like to have the axes more

问题 Java and C# (Xamarin.Android) accepted I have a MediaRecorder that streams the cameraframes onto a TextureView (basic camera2 approach) the TextureView fills my screen. I want the video to fill the screen but keep the aspect ratio. I know I have to eventually cut of either left/right or top/bottom parts of the video, to keep the aspect ratio. How can I make the video fit the TextureView and "zoom in" until the whole screen is filled? I don't want "black bars" that compromise for the ratio to

问题 Is there any way to maintain the aspect ratio of a drawable when applied as background on a Button (cannot use ImageButton (need possibility for text on the Button ), cannot use setCompoundDrawables() , because that also doesn't meet my requirements (I made my own class to support adding backgrounds while still retaining the original android default button, plus I need to set te background in the middle of the button, not left, right, top or bottom)). I tried a solution with a ScaleDrawable ,

问题 I have discovered that certain tablets (e.g. Samsung SM-T210 - Galaxy Tab 3) have equal horizontal and vertical angles of view (implying aspect ratio = 1), while NONE of their camera1.parameters supported picture sizes have an aspect ratio of 1 (closest being 1.33). What's going on? Are pixel pitches different in the x and y directions? Is come kind of cropping always applied? I am testing an augmented reality app, and I need to have a very clear understanding of how an optical point maps

问题 I currently have a user control that contains items that have a certain X, Y coordinate and there are limits to what those points must be within. In this case those positions are 0 > X > 40 and 0 > Y > 80 (40x80). The control I am hosting those items in is dynamic but has a certain aspect ratio based on window size. I need to translate those X & Y coordinates into relative locations within the user control. Any help is greatly apprecaited! Thanks in advance! If it matters/helps, I'm using
