aspect-ratio

all. How to change resolution of the video with aspect ratio with FFmpeg? There are options http://manpages.ubuntu.com/manpages/oneiric/man1/ffmpeg.1.html -s size Set frame size. The format is wxh (ffserver default = 160x128, ffmpeg default = same as source). The following abbreviations are recognized: and -aspect aspect Set the video display aspect ratio specified by aspect. aspect can be a floating point number string, or a string of the form num:den, where num and den are the numerator and denominator of the aspect ratio. For example "4:3", "16:9", "1.3333", and "1.7777" are valid argument

With imagemagick, I'd like to crop an image, in a minimal fashion, so that it fits a given aspect ratio. Example: given an image of, say, 3038 x 2014 px, I want to crop it to have a 3:2 aspect ratio. The resulting image would then be 3021 x 2014 px, cropped from the, say, center of the original image. So looking for a command looking something like convert in.jpg -gravity center -crop_to_aspect_ratio 3:2 out.jpg . 1. Specific target resolution If your goal at the end is to have a certain resolution (for example 1920x1080) then it's easy, using -geometry , the circumflex/hat/roof/house symbol (

I have a gallery on my site where users can upload images. I would like the images to sit in a div that maintains its height, the images should be no larger than 500px in height. The width should be automatic to maintain aspect ratio. HTML: <div id="gallery"> <img src="uploads/my-dynamic-img.jpg"> </div> I've tried this CSS: #gallery{ height: 500px; img{ max-height: 500px; max-width: 100%; } } The above works well, the gallery is always 500px high and images never exceed 500px in height. I run into problems though with smaller images, if a user uploads a really small image, I would like it

I have a UIButton in my iPhone app. I set its size to 100x100. I have an image that is 400x200 that I wish to display in the button. The button STILL needs to stay at 100x100... and I want the image to downsize to fit... but keep the correct aspect ratio. I thought that's what "Aspect Fit" was used for. Do I include my image with setImage, or setBackgroundImage? Do I set AspectFit for the button? or the image? or the background image? (I need the smaller images to INCREASE in size. While larger images should DESCREASE in size. Always keeping the button at 100x100.) I've tried countless

I have an application in which end-users can size and position images in a designer. Since the spec calls for the image to be "stretched" to the containing control, the end user can end up with an awkwardly stretched image. To help the user with image sizing I am thinking of implementing a smart resizer function which would allow the the user to easily fix the aspect ratio of the picture so that it no longer appears stretched. The quick way to solve this is to actually provide two options: 1) scale from width 2) scale from height. The user chooses the method and the algorithm adjusts the size

Consider the following layout file: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent"> <android.support.constraint.ConstraintLayout android:id="@+id/activity_main" android:layout_width="match_parent" android:layout_height="match_parent" android:background="#FF0000" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity

Back in the day, 800 x 600 was the screen resolution to design for - and maybe 640 x 480. Then along came 1024 x 768, etc, etc, etc. But then it gets worse: now we have not only different resolutions but also different aspect ratios. What strategies do people use to accommodate today's ever-expanding range of screen sizes and aspect ratios? (BTW - I was only thinking about laptop / desktop hardware, but of course there's smart-phones and tablets to consider too.) I know this would be a somewhat controversial opinion, but I'd say it anyway: Don't Don't design for multiple screen sizes or aspect
