C/C++: Compressing(gz) data without using temporary file -


इस सवाल का पहले से ही एक उत्तर है: < / P>

  • 1 उत्तर

    मेरे पास कुछ डेटा है सरणी, 

      uchar * डेटा = "संपीड़ित होने वाला डेटा।"; [कुछ डेटा]   
     मैं इस डेटा को संकुचित करना चाहता हूं ( gz ) और बफर में आउटपुट प्राप्त करना चाहते हैं।  
      uchar gzData [MAX_LEN];   
     ऐसा करने का एक तरीका है:  
      1. एक `ऑगस्टस्ट्रीम` वस्तु बनाना 2. इस डेटा को एक अस्थायी फ़ाइल में लिखना 3. अस्थायी फ़ाइल को बंद करें। 3. एक `इस्ट्रीम ™ ऑब्जेक्ट बनाएँ 4. अगर ऑस्ट्रिस्ट ऑब्जेक्ट का इस्तेमाल करते हुए बफ़र में अस्थायी फ़ाइल पढ़ें।   
     लेकिन मैं इस के लिए एक अस्थायी फ़ाइल का उपयोग नहीं करना चाहता क्योंकि यह पूरी प्रक्रिया धीमा कर रहा है।  
     क्या इस डेटा का उपयोग किए बिना संपीड़ित करने का कोई सीधा तरीका है किसी भी मध्यवर्ती फ़ाइल   
     
     
     आप ऐसा करने के लिए फ़िल्टरिंग  streambuf  का उपयोग कर सकते हैं उड़ान पर। यह बहुत आसान है, लेकिन बूस्ट :: Iostreams ने पहले से ही आपके लिए किया है।

python - how we can use ajax() in views.py in django? -

I have a little code here. Could you please tell me what this code really does? please. Here in the AJAX call: $ .ajax ({url: "{% url} upload_document '%}", type: "POST", data : {Csrfmiddletoken: document.getElementsByName ('csrfmiddletoken') [0] Price, Title: document.getElementById ('title'). Value, // document: document: document.getElementById ('document'),}, datatype: "Jason", success: function (feedback) {if (feedback == "true") {// success} other {// attachment errors}}}); How AJAX works in the Django and how we can see the AJAX request. Here is the idea of ​​my thoughts def upload_document (requested): Print request. POTT print request FILES if request.is_ajax (): If request.method == 'POST': form = UploadForm (request.POST, request.FILES, user = request.user) if form.is_valid (): Form.save () return HTTPPCS (SimpleJason Dumps ('True'), Mime Type = 'App / Jason') Other:...

matlab - Using loops to get multiple values into a cell -

I have 31 topics (S1, S2, S3, S4, etc.) 3 images in each topic, opposite 1 IMG, Contrast 2 IMG and Contrast 3 Are IMG I p In a NX1 cell named P, I would like to use a loop to get all the paths of contrasts from all the subjects: data / S1 / contrast1.img / S1 / contrast2.img data / S1 / contrast3.img data / s2 / contrast1.img data / S2 / contrast2.img Data / S2 / contrast3.img ... Data / S31 / contast3.img This is what I've tried: A = {'S1', 'S2', 'S3', ..., 'S31'}; % All topics C = {'contrast1.img', 'contrast2.img', 'contrast3.img'}; For each = P = cell (31 * 3,1) for each topic, the required contrast images: Length = A for Jammu = 1: Length (C) P {j} = spm_select ('FPList', Fullfile (data_path, q {i}) sprint ('% s', cell2mat (c))); % Of each topic is to select three contrast images, it works in my script, it is probably not 100% correct, because I had to simplify this example. End of ...

python - Sequence Pattern recognition with Pybrain -

Image
I am constantly trying to use recurrent neural networks to classify a series of data. To be more specific, I have a sequence of sensor reading (which is continuous over time), I have to learn an algorithm which can detect the state related to this pattern, given the readings change. Example: Time step_1: 1.4 Time step_2: 1 Time step_3: 0.8 State = New Sequence: Time Phase 1: 0.4 Time Phase 2: 0.3 Time Phase 3: 0.1 State = Sitting I actually have 12 censors, I'm just showing a sequence of numbers for convenience. (Numbers are not real, I'm just trying to fulfill this idea)! I am trying to make my network with PyBrain RNN, however, I can not get a Data Set Container that can detect it, like information I tried to use sequential data But after some testing I came to know that this number is the next element in the sequence of numbers. Here's how I prepare my dataset: self.alldata = SequentialDataSet (ds.num_features, 1) # Now add samples to the dat...
