openCV imread limit for large or huge images Mat bug #3258

由 倖福魔咒の 提交于 2021-02-20 02:52:42
问题 I've been searching for days about this issue and didn't find any solved thread. I need loading pretty large images (4 GB and beyond, either .tiff / .png) into openCV code, by means of a simple src = imread(filepath, 1); I'm using Visual Studio 2013, C++. Though I'm using a 96Gb-RAM machine, runtime alerts are coming out when loading these large images by OpenCV's "imread" function. Been trying with smaller and smaller images/files untill the point they are indeed read/loaded, so we know it's

In Python, what is `sys.maxsize`?

问题 I assumed that this number ( 2^63 - 1 ) was the maximum value python could handle, or store as a variable. But these commands seem to be working fine: >>> sys.maxsize 9223372036854775807 >>> a sys.maxsize + 1 >>> a 9223372036854775808 So is there any significance at all? Can Python handle arbitrarily large numbers, if computation resoruces permitt? Note, here's the print-out of my version is: >>> sys.version 3.5.2 |Anaconda custom (64-bit)| (default, Jul 5 2016, 11:41:13) [MSC v.1900 64 bit

Java NegativeArraySizeException in byte

问题 I want to send file with OutputStream, so I use byte[] = new byte[size of file ] but I don't know what the max size is that i can use. This is my code. File file = new File(sourceFilePath); if (file.isFile()) { try { DataInputStream diStream = new DataInputStream(new FileInputStream(file)); long len = (int) file.length(); if(len>Integer.MAX_VALUE){ file_info.setstatu("Error"); } else{ byte[] fileBytes = new byte[(int) len]; int read = 0; int numRead = 0; while (read < fileBytes.length &&

LWP set max_size but still get content

由 为君一笑 提交于 2019-12-11 09:34:37
问题 I am using LWP to get the content from some sites and whenever the page size is larger than one megabyte, I would like LWP to stop downloading the page. This is accomplished with this code: my $ua = LWP::UserAgent->new; $ua->max_size(1024); And it works fine. The only problem is that even when the page is over 1mb, I would still like to be able to get the content of what it has downloaded so far. However, whenever I do this (the traditional way to get content with LWP when there are no errors

问题 On 32 bit System. std::vector<char>::max_size() returns 2 32 -1, size of char — 1 byte std::vector<int>::max_size() returns 2 30 -1, size of int — 4 byte std::vector<double>::max_size() returns 2 29 -1, size of double — 8 byte can anyone tell me max_size() depends on what? and what will be the return value of max_size() if it runs on 64 bit system. 回答1: Simply get the answer by Vector<data-type>v; Cout<< v.max_size(); Or we can get the answer by (2^bit of system)/sizeof(datatype) -1 Eg for 64

http request with timeout, maximum size and connection pooling

由 前提是你 提交于 2019-11-28 21:57:52
I'm looking for a way in Python (2.7) to do HTTP requests with 3 requirements: timeout (for reliability) content maximum size (for security) connection pooling (for performance) I've checked quite every python HTTP librairies, but none of them meet my requirements. For instance: urllib2: good, but no pooling import urllib2 import json r = urllib2.urlopen('https://github.com/timeline.json', timeout=5) content = r.read(100+1) if len(content) > 100: print 'too large' r.close() else: print json.loads(content) r = urllib2.urlopen('https://github.com/timeline.json', timeout=5) content = r.read

How to prevent Warning: POST Content-Length and memory size

由 ＊爱你＆永不变心＊ 提交于 2019-11-28 11:13:20
Currently when user uploads a photo the page says "Warning: POST Content-Length of XXX bytes exceeds the limit of 21000000 bytes in Unknown on line 0". I know what that means and I am NOT looking for the solultions like the increasing the max_upload values or even memory_size_limit... Because users may and users will upload terabytes of nonsense even if you explicitly tell them only max 20MB files and only images are allowed. I am looking for a solution on: How to prevent this warning(s) to even happen? OR at least: How to prevent displaying of this warning(s)? EDIT: PLEASE READ ! - Please
