问题 Scenario : I convert a pdf file to base64 and put it in an xml, and Problem : when I receive the xml I will have to convert this base64 data back to the original pdf file using SQL Server and store it somewhere. I found this link but could not figure out how to do it. This is what I have: DECLARE @SQLcommand VARCHAR(8000), @MyOriginalFile VARCHAR(8000), @RawData VARCHAR(8000) SET @RawData = 'JVBERi0x etc' SET @SQLcommand = 'bcp "SELECT @MyOriginalFile = @RawData" queryout "\\MY-SERVER

问题 I have a 20GB library of images stored as a high-dimensional numpy array. This library allows me to these use images without having to generate them anew each time. Now my problem is that np.load("mylibrary") takes as much time as it would take to generate a couple of those images. Therefore my question is: Is there a way to store a numpy array such that it is readily accessible without having to load it? Edit: I am using PyCharm 回答1: I would suggest h5py which is a Pythonic interface to the

问题 I was wondering if there is a method similar to UIImageWriteToSavedPhotosAlbum(UIImage *image, id completionTarget, SEL completionSelector, void *contextInfo), that saves Videos taken from the iphone camera to the u sers Photo Albums... been trying to look for it in apple docs but havent found anything.
