问题 We are capturing a visible tab in a Chrome browser (by using the extensions API chrome.tabs.captureVisibleTab) and receiving a snapshot in the data URI scheme (Base64 encoded string). Is there a JavaScript library that can be used to scale down an image to a certain size? Currently we are styling it via CSS, but have to pay performance penalties as pictures are mostly 100 times bigger than required. Additional concern is also the load on the localStorage we use to save our snapshots. Does

问题 I have custom UITableViewCell with 4 UIImageViews it. I set image in UIImageView.image different size, but i want to scale it proportion (without black lines top/bottom and left/right. How can i do it? 回答1: You can use the contentMode property to get your image scaled.

问题 i'm having an issue with the top and bottom of an image getting cut off, on a website that uses a full screen background image. i initially thought that the padding: 0px and margin: 0px properties (set for html, body in the CSS) were the culprit, but i tried removing these to no avail. it should be noted that this layout was borrowed from elsewhere. there is a separate .js file, without any styling in it, that rotates the background image. which part(s) of my CSS are the problem and how can i
