• python convert 12 bit image encoded in a string to 8 bit png

  - by ks

  I have a string that is read from a usb apogee camera that is a 12-bit grayscale image with the 12-bits each occupying the lowest 12 bits of 16-bits words. I want to create a 8-bit png from this string by ignoring the lowest 4 bits. I can convert it to a 16-bit image where the highest 4 bits are always zero using PIL with import Image imageStr is the image string imageSize is the image size img=Image.fromstring("I", imageSize, imageStr, "raw", "I;16", 0,1) img.save("MyImage.png", "PNG") Anyway I can do something similar to create a 8-bit image without completely unpacking the string doing arithmetic and making a new string?

• How to using String.split in this case?

  - by hoang nguyen

  I want to write a fuction like that: - Input: "1" -> return : "1" - Input: "12" -> return : ["1","2"] If I use the function split(): String.valueOf("12").split("") -> ["","1","2"] But, I only want to get the result: ["1","2"]. What the best way to do this? Infact, I can do that: private List<String> decomposeQuantity(final int quantity) { LinkedList<String> list = new LinkedList<String>(); int parsedQuantity = quantity; while (parsedQuantity > 0) { list.push(String.valueOf(parsedQuantity % 10)); parsedQuantity = parsedQuantity / 10; } return list; } But, I want to use split() for having an affective code

• How to convert unicode character to its escaped ascii equivalent in c#

  - by Grant

  Hi, i am beginning with a string containing an encoded unicode character "& #xfc;". I pass the string to an object that performs some logic and returns another string. That string is converting the original encoded character to its unicode equivalent "ü". I need to get the original encoded character back but so far am not able. I have tried using the HttpUtility.HtmlEncode() method but that is returning "& #252;" which is not the same. Can anyone help?

• Best way to reverse a string in C# 2.0

  - by Guy

  I've just had to write a string reverse function in C# 2.0 (i.e. LINQ not available) and came up with this: public string Reverse(string text) { char[] cArray = text.ToCharArray(); string reverse = String.Empty; for (int i = cArray.Length - 1; i > -1; i--) { reverse += cArray[i]; } return reverse; } Personally I'm not crazy about the function and am convinced that there's a better way to do it. Is there?

• C++ STL: Trouble with string iterators

  - by Rosarch

  I'm making a simple command line Hangman game. void Hangman::printStatus() { cout << "Lives remaining: " << livesRemaining << endl; cout << getFormattedAnswer() << endl; } string Hangman::getFormattedAnswer() { return getFormattedAnswerFrom(correctAnswer.begin(), correctAnswer.end()); } string Hangman::getFormattedAnswerFrom(string::const_iterator begin, string::const_iterator end) { return begin == end? "" : displayChar(*begin) + getFormattedAnswerFrom(++begin, end); } char Hangman::displayChar(const char c) { return c; } (Eventually, I'll change this so displayChar() displays a - or a character if the user has guessed it, but for simplicity now I'm just returning everything.) When I build and run this from VS 2010, I get a popup box: Debug Assertion Failed! xstring Line: 78 Expression: string iterator not dereferenceable What am I doing wrong?

• c# counting identical strings from text file

  - by Winkz

  I have a foreach statement where I go through several lines from a text file, where I have trimmed down and sorted out the lines I need. What I want to do is count up on how many times an identical string is present. How do I do this? Here is my code. It's the second if statement where I am stuck: foreach (string line in lines.Where(l => l.Length >= 5)) { string a = line.Remove(0, 11); if ((a.Contains(mobName) && a.Contains("dies"))) { mobDeathCount++; } if (a.Contains(mobName) && a.Contains("drops")) { string lastpart = a.Substring(a.LastIndexOf("drops")); string modifiedLastpart = lastpart.Remove(0, 6); } Heres what some of the lines look like: a bag of coins a siog brandy a bag of coins a bag of coins the Cath Shield a tattered scroll So what im trying to do is counting up there are 3 lines with bag of coins. But i need to make it so that it can be everything, theres a drop lists thats huge. So cant add all of em, would take too long

• For which substring of the string1 matches occurred with the string2.

  - by Harikrishna

  I want to know that in particular string1 for which substring of the string1 the string2 matches.Like String str1="Order Number Order Time Trade Number"; String str2="Order Tm"; string regex = Regex.Escape(str2.Replace(@"\ ", @"\s*"); bool isColumnNameMatched = Regex.IsMatch(str1, regex, RegexOptions.IgnoreCase); I am using regex because "Order Tm" will also matches "Order Time".It gives bool value that matches occurred or not. But if it str2 is in str1 then I want to know at which position in the str1 the str2 matches. Like str2="Order Tm" then something like that returns the string which is matched with str2 in the str1.Here str2="Order Tm" then it should return like in the str1,Order Time is the substring where matches is occurred.

• What are the disadvantages of using a StringBuilder?

  - by stickman

  I know that StringBuilder is more efficient than a normal string when processing code which modifies the string value a lot because although strings act like value types, they are actually reference, which makes them immutable so every time we change it, we need to create a new reference in memory. My question is that, why doesn't .NET just use stringBuilder by default? There must be some disadvantages of it over just using String. Can anyone tell me what they are? The only thing I can think of is perhaps it is a heavier object and it takes more time to instantiate so if you aren't changing the string too much, this would override the benefits of StringBuilder

• Hashing (hidding) strings in Python

  - by Lucas

  What I need is to hash a string. It doesn't really have to be secure because its just going to be a hidden pharse in the text file (simply it doesn't have to be recognizable for a human-eye). It should not be just a random string because when user will be typing the string I would like to hash it and compare it with already hashed one (in the text file). What would be the best for this purpose? Can it be done with the own class?

• Java: equivalent to C's strnicmp? (both startsWith and ignoreCase)

  - by Jason S

  String string1 = "abCdefGhijklMnopQrstuvwYz"; String string2 = "ABC"; I had been using string1.startsWith(string2), which would return false in the above example, but now I need to ignore case sensitivity, and there is not a String.startsWithIgnoreCase(). Besides doing string1.toLowerCase.startsWith(string2.toLowerCase()); is there an efficient way to see if string1 starts with string2 in a case-insensitive way?

• rb_str_modify() equivalent in the Ruby language

  - by Hagbard

  I was trying to add a method to the String class. This method should mutate the current string (of course it would be possible to write a not mutating version but I'd prefer the mutating one). I had no idea how to do this and after some googling I found the method rb_str_modify which makes a given string mutable. That's exactly what I need but I couldn't find an equivalent in the Ruby language. Did I miss something or is there really no possibility in the language itself?

• Removing words from a file

  - by user1765792

  I'm trying to take a regular text file and remove words identified in a separate file (stopwords) containing the words to be removed separated by carriage returns ("\n"). Right now I'm converting both files into lists so that the elements of each list can be compared. I got this function to work, but it doesn't remove all of the words I have specified in the stopwords file. Any help is greatly appreciated. def elimstops(file_str): #takes as input a string for the stopwords file location stop_f = open(file_str, 'r') stopw = stop_f.read() stopw = stopw.split('\n') text_file = open('sample.txt') #Opens the file whose stop words will be eliminated prime = text_file.read() prime = prime.split(' ') #Splits the string into a list separated by a space tot_str = "" #total string i = 0 while i < (len(stopw)): if stopw[i] in prime: prime.remove(stopw[i]) #removes the stopword from the text else: pass i += 1 # Creates a new string from the compilation of list elements # with the stop words removed for v in prime: tot_str = tot_str + str(v) + " " return tot_str

• How to create a datastore.Text object out of an array of dynamically created Strings?

  - by Adrogans

  I am creating a Google App Engine server for a project where I receive a large quantity of data via an HTTP POST request. The data is separated into lines, with 200 characters per line. The number of lines can go into the hundreds, so 10's of thousands of characters total. What I want to do is concatenate all of those lines into a single Text object, since Strings have a maximum length of 500 characters but the Text object can be as large as 1MB. Here is what I thought of so far: public void doPost(HttpServletRequest req, HttpServletResponse resp) { ... String[] audioSampleData = new String[numberOfLines]; for (int i = 0; i < numberOfLines; i++) { audioSampleData[i] = req.getReader().readLine(); } com.google.appengine.api.datastore.Text textAudioSampleData = new Text(audioSampleData[0] + audioSampleData[1] + ...); ... } But as you can see, I don't know how to do this without knowing the number of lines before-hand. Is there a way for me to iterate through the String indexes within the Text constructor? I can't seem to find anything on that. Of note is that the Text object can't be modified after being created, and it must have a String as parameter for the constructor. (Documentation here) Is there any way to this? I need all of the data in the String array in one Text object. Many Thanks!

  EDIT: IT'S FIXED, THANKS FOR THE HELP! So basically I have an array of strings, a question and an answer public static String[][] triviaData = { {"Question2", "Answer1"}, {"Question2", "Answer2"}, {"Question3", "Answer3"}, }; And I am trying to make a method that validates an entered input, lets call the entered input enteredAnswer. enteredAnswer is stored as a String. I am trying to validate that the enteredAnswer is the same as the second index of the array. if (enteredAnswer.equalsIgnoreCase(triviaData[Config.CurrentQuestion][1])) { This is the code I tried, but I get the error "Cannot invoke equalsIgnoreCase(String) on the array type String[]" I am a beginner programmer so if you could help me out it would be highly appreciated. Thanks. enteredAnswer is stored as public String[] enteredAnswer;

• printf("... %c ...",'\0') and family - what will happen?

  - by SF.

  How will various functions that take printf format string behave upon encountering the %c format given value of \0/NULL? How should they behave? Is it safe? Is it defined? Is it compiler-specific? e.g. sprintf() - will it crop the result string at the NULL? What length will it return? Will printf() output the whole format string or just up to the new NULL? Will va_args + vsprintf/vprintf be affected somehow? If so, how? Do I risk memory leaks or other problems if I e.g. shoot this NULL at a point in std::string.c_str()? What are the best ways to avoid this caveat (sanitize input?)

• DexFile.class error in eclipse

  - by ninjasense

  I get this weird error everytime I debug in eclipse. It just seemed to appear one day and I was wondering if anyone else was running int the same problem. It does not affect my app in anyway visibly and does not cause a crash but it is an annoyance while debugging. Here is the full error: // Compiled from DexFile.java (version 1.5 : 49.0, super bit) public final class dalvik.system.DexFile { // Method descriptor #8 (Ljava/io/File;)V // Stack: 3, Locals: 2 public DexFile(java.io.File file) throws java.io.IOException; 0 aload_0 [this] 1 invokespecial java.lang.Object() [1] 4 new java.lang.RuntimeException [2] 7 dup 8 ldc <String "Stub!"> [3] 10 invokespecial java.lang.RuntimeException(java.lang.String) [4] 13 athrow Line numbers: [pc: 0, line: 4] Local variable table: [pc: 0, pc: 14] local: this index: 0 type: dalvik.system.DexFile [pc: 0, pc: 14] local: file index: 1 type: java.io.File // Method descriptor #18 (Ljava/lang/String;)V // Stack: 3, Locals: 2 public DexFile(java.lang.String fileName) throws java.io.IOException; 0 aload_0 [this] 1 invokespecial java.lang.Object() [1] 4 new java.lang.RuntimeException [2] 7 dup 8 ldc <String "Stub!"> [3] 10 invokespecial java.lang.RuntimeException(java.lang.String) [4] 13 athrow Line numbers: [pc: 0, line: 5] Local variable table: [pc: 0, pc: 14] local: this index: 0 type: dalvik.system.DexFile [pc: 0, pc: 14] local: fileName index: 1 type: java.lang.String // Method descriptor #22 (Ljava/lang/String;Ljava/lang/String;I)Ldalvik/system/DexFile; // Stack: 3, Locals: 3 public static dalvik.system.DexFile loadDex(java.lang.String sourcePathName, java.lang.String outputPathName, int flags) throws java.io.IOException; 0 new java.lang.RuntimeException [2] 3 dup 4 ldc <String "Stub!"> [3] 6 invokespecial java.lang.RuntimeException(java.lang.String) [4] 9 athrow Line numbers: [pc: 0, line: 6] Local variable table: [pc: 0, pc: 10] local: sourcePathName index: 0 type: java.lang.String [pc: 0, pc: 10] local: outputPathName index: 1 type: java.lang.String [pc: 0, pc: 10] local: flags index: 2 type: int // Method descriptor #28 ()Ljava/lang/String; // Stack: 3, Locals: 1 public java.lang.String getName(); 0 new java.lang.RuntimeException [2] 3 dup 4 ldc <String "Stub!"> [3] 6 invokespecial java.lang.RuntimeException(java.lang.String) [4] 9 athrow Line numbers: [pc: 0, line: 7] Local variable table: [pc: 0, pc: 10] local: this index: 0 type: dalvik.system.DexFile // Method descriptor #30 ()V // Stack: 3, Locals: 1 public void close() throws java.io.IOException; 0 new java.lang.RuntimeException [2] 3 dup 4 ldc <String "Stub!"> [3] 6 invokespecial java.lang.RuntimeException(java.lang.String) [4] 9 athrow Line numbers: [pc: 0, line: 8] Local variable table: [pc: 0, pc: 10] local: this index: 0 type: dalvik.system.DexFile // Method descriptor #32 (Ljava/lang/String;Ljava/lang/ClassLoader;)Ljava/lang/Class; // Stack: 3, Locals: 3 public java.lang.Class loadClass(java.lang.String name, java.lang.ClassLoader loader); 0 new java.lang.RuntimeException [2] 3 dup 4 ldc <String "Stub!"> [3] 6 invokespecial java.lang.RuntimeException(java.lang.String) [4] 9 athrow Line numbers: [pc: 0, line: 9] Local variable table: [pc: 0, pc: 10] local: this index: 0 type: dalvik.system.DexFile [pc: 0, pc: 10] local: name index: 1 type: java.lang.String [pc: 0, pc: 10] local: loader index: 2 type: java.lang.ClassLoader // Method descriptor #37 ()Ljava/util/Enumeration; // Signature: ()Ljava/util/Enumeration<Ljava/lang/String;>; // Stack: 3, Locals: 1 public java.util.Enumeration entries(); 0 new java.lang.RuntimeException [2] 3 dup 4 ldc <String "Stub!"> [3] 6 invokespecial java.lang.RuntimeException(java.lang.String) [4] 9 athrow Line numbers: [pc: 0, line: 10] Local variable table: [pc: 0, pc: 10] local: this index: 0 type: dalvik.system.DexFile // Method descriptor #30 ()V // Stack: 3, Locals: 1 protected void finalize() throws java.io.IOException; 0 new java.lang.RuntimeException [2] 3 dup 4 ldc <String "Stub!"> [3] 6 invokespecial java.lang.RuntimeException(java.lang.String) [4] 9 athrow Line numbers: [pc: 0, line: 11] Local variable table: [pc: 0, pc: 10] local: this index: 0 type: dalvik.system.DexFile // Method descriptor #42 (Ljava/lang/String;)Z public static native boolean isDexOptNeeded(java.lang.String arg0) throws java.io.FileNotFoundException, java.io.IOException; } Thanks

• Parsing with BeautifulSoup, error message TypeError: coercing to Unicode: need string or buffer, NoneType found

  - by Samsun Knight

  so I'm trying to scrape an Amazon page for data, and I'm getting an error when I try to parse for where the seller is located. Here's my code: #getting the html request = urllib2.Request('http://www.amazon.com/gp/offer-listing/0393934241/') opener = urllib2.build_opener() #hiding that I'm a webscraper request.add_header('User-Agent', 'Mozilla/5 (Solaris 10) Gecko') #opening it up, putting into soup form html = opener.open(request).read() soup = BeautifulSoup(html, "html5lib") #parsing for the seller info sellers = soup.findAll('div', {'class' : 'a-row a-spacing-medium olpOffer'}) for eachseller in sellers: #parsing for price price = eachseller.find('span', {'class' : 'a-size-large a-color-price olpOfferPrice a-text-bold'}) #parsing for shipping costs shippingprice = eachseller.find('span' , {'class' : 'olpShippingPrice'}) #parsing for condition condition = eachseller.find('span', {'class' : 'a-size-medium'}) #parsing for seller name sellername = eachseller.find('b') #parsing for seller location location = eachseller.find('div', {'class' : 'olpAvailability'}) #printing it all out print "price, " + price.string + ", shipping price, " + shippingprice.string + ", condition," + condition.string + ", seller name, " + sellername.string + ", location, " + location.string I get the error message, pertaining to the 'print' command at the end, "TypeError: coercing to Unicode: need string or buffer, NoneType found" I know that it's coming from this line - location = eachseller.find('div', {'class' : 'olpAvailability'}) - because the code works fine without that line, and I know that I'm getting NoneType because the line isn't finding anything. Here's the html from the section I'm looking to parse: <*div class="olpAvailability"> In Stock. Ships from WI, United States. <*br/><*a href="/gp/aag/details/ref=olp_merch_ship_9/175-0430757-3801038?ie=UTF8&amp;asin=0393934241&amp;seller=A1W2IX7T37FAMZ&amp;sshmPath=shipping-rates#aag_shipping">Domestic shipping rates</a> and <*a href="/gp/aag/details/ref=olp_merch_return_9/175-0430757-3801038?ie=UTF8&amp;asin=0393934241&amp;seller=A1W2IX7T37FAMZ&amp;sshmPath=returns#aag_returns">return policy</a>. <*/div> (but without the stars - just making sure the HTML doesn't compile out of code form) I don't see what's the problem with the 'location' line of code, or why it's not pulling the data I want. Help?
