问题 I need to find a way to re-size an input raster image (such as jpg) to a specified width/height resolution (given in pixels). It would be great if PyQt while resizing a new image would keep an original image's aspect ratio (so there is no stretching but scaling only). src = '/Users/usrName/Images/originalImage.jpg' (2048x1024) (rectangular image 2:1 ratio) dest= '/Users/usrName/Images/originalImage_thumb.jpg' (64x64) (output image is square 1:1 ratio). Thanks in advance! POSTED RESULTED FUNC:

问题 I try to stretch video in aim to fill videoview. The target is to create view that in device look like the first pic (like it look in layout preview). Most of the answers to this questions refer to this link. I tried this but I still didn't fill video view. This my layout code : <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"

问题 I'm trying to position elements in my Canvas relative to my background. Window is re-sized keeping the aspect ratio. Background is stretched with window size. The problem is once window is re-sized the element positions are incorrect. If window is re-sized just a little, elements will adjust their size a bit and would be still in the correct position, but if window is re-sized to double it's size then positioning is completely off. So far I used Grid , but it was to no avail as well. Here is

问题 My initial problem like many others is to keep a DIV A with a fixed aspect ratio (pure CSS/no JS). It is intended to be reused in any parent DIV B regardless the sizing of B. DIV A should fit the smallest size of B. In this animation, you can see the RED div that is always a square and that fits the outermost div smallest size. No vh or vw or vmin or vmax is used and I don't want to use any of them because vh is sometimes no more reliable to really represent the viewport height (see CSS3

问题 I have not been able to find a solution to this and am willing to change whatever I need to as long as I can keep a couple things. The entire list element needs to be a link, the text within that link needs to be centered to the list item which has a background image. I need this fluid so I choose to use the padding-top to maintain the aspect ratio and to create the correct height. With using that padding top to create the height, I can not for the life of me figure out how to get the text
