问题 I want to delete all *.jpg files in a specific folder and all its subfolders which have e.g. width unequal 800 and height unequal 600 (leaving only 800x600 jpg images). Can someone tell me how to do this in Powershell? I know I can remove *.jpg images with Get-ChildItem -Path .\ -Filter *.jpg -Recurse | foreach ($_) {remove-item $_.fullname} But I can't seem to find how to select height/width of an image. 回答1: You could use the System.Drawing.Image .NET Object: $(Get-ChildItem -Filter *.jpg)

问题 I am trying to upload and save an image file using Django and respond the image itself to use in ongoing javascript functions. The problem is that the image doesn't get saved, the request.FILES is empty. When using request.body, I can see that there is not the actual file path, but a C://fakepath. Because I want the uploaded image to save immediately, I do the post using a jquery ajax call, the data is then saved creating a new Object, then the function should return a success, which it does.

To ilustrate this, see this image: Text detected with CRAFT I am interested in detecting the code part, which is: FBIU0301487. However, it seems that the caracter 'F' cannot be detected even using a threshold equals to zero, i.e. let every bounding box be consired as a valid detection.
