问题 On Mac, is it possible to use AppleScript/Automator to show a preview of an image in the background, while the Automator app is running? I have hundreds of images to which I want to add meta data so that they can be displayed on a web site. My plan is to create a *.meta file with the same name as the original image, so that a PHP script can read in the meta data at the same time that it generates the URL for the image. I have created an AppleScript file (see below), which I have embedded in

问题 I currently have files stored in Firebase Storage. I want to be able to generate a file preview for each file in real time (mapping).

In a general case the size WxH I want is not supported by the camera therefore I will need to crop the captured picture in order to match my specifications. This apparently simple program is driving me crazy for the problem of "good" corrispondence among preview and picture sizes and format. Let me explain: I need a format (let's give some numbers: 800x600) for the output image, and I

问题 Has anyone else noticed that Chrome's preview tab in the network panel now outputs json as a string (just as the response tab) rather than formatting it into a tree? If so, can you point me in the right direction to get it solved? Chrome version is 43.0.2357.81 m Cheers! 回答1: Do you set right content type header for the response?

Use one output of the tee
