  • PHP-GD: Dealing with Unicode characters

    - by sehugg
    I am developing a web service that renders characters using the PHP GD extension, using a user-selected TTF font. This works fine in ASCII-land, but there are a few problems: The string to be rendered comes in as UTF-8. I would like to limit the list of user-selectable fonts to be only those which can render the string properly, as some fonts only have glyphs for ASCII characters, ISO 8601, etc. In the case where some decorative characters are included, it would be fine to render the majority of characters in the selected font and render the decorative characters in Arial (or whatever font contains the extended glyphs). It does not seem like PHP-GD has support for querying the font metadata sufficiently to figure out if a character can be rendered in a given font. What is a good way to get font metrics into PHP? Is there a command-line utility that can dump in XML or other parsable format?

  • Lost in UTF-8 hell. (Django and Python)

    - by user140314
    I am working through the Django RSS reader project here. The RSS feed will read something like "OKLAHOMA CITY (AP) — James Harden let". The RSS feed's encoding reads encoding="UTF-8" so I believe I am passing utf-8 to markdown in the code snippet below. The em dash is where it chokes. I get the Django error of "'ascii' codec can't encode character u'\u2014' in position 109: ordinal not in range(128)" which is an UnicodeEncodeError. In the variables being passed I see "OKLAHOMA CITY (AP) \u2014 James Harden". The code line that is not working is: content = content.encode(parsed_feed.encoding, "xmlcharrefreplace") I am using markdown 2.0, django 1.1, and python 2.4. What is the magic sequence of encoding and decoding that I need to do to make this work? Thanks.

  • Generic Text Only printer driver mangles control codes

    - by Terry
    If an escape character (or most other characters < 0x20) is sent to the generic / text only printer it gets printed as a period. Using the code in the WinDDK is it possible to 'correct' this behaviour so that it passes it through unmodified? The general scenario for this is that some application ('user app') outputs a document to a windows printer. My application requires this data in plain text form and so what I do is run a generic / text only printer that talks to a virtual com port. This generally works fine except where the 'user app' outputs binary data to the print queue without using the correct mechanism (which seems to work fine on some printer drivers, such as the Epson POS ones, but not the generic / text only one). I've tried changing the print processor selection without success and also tried looking at the gtt files to see if I could readily map in these characters as though they were printable, but the minidriver tool won't let me do that. Any suggestions?

  • How to make Excel strip ALL quotes from CSV text fields

    - by Klay
    When importing a CSV file into Excel, it only strips the double-quotes from the FIRST field on the line, but leaves them on all other fields. How can I force Excel to strip the quotes from ALL strings? For instance, I have a CSV file: "text1", "text2", "numeric1", "numeric 2" "abc", "def", 123, 456 "abc", "def", 123, 456 "abc", "def", 123, 456 "abc", "def", 123, 456 I import it into Excel using Data Import External Data Import Data. I specify that the fields are delimited by commas, and that the text delimiter is the double-quote character. Both the data preview and the actual Excel spreadsheet columns only strip the double-quotes from the first text field. All other text fields still have quotes around them. What's really strange is that Access is able to import this data correctly (i.e. strips quotes from every text field. Note that this is NOT a matter of internal commas or quotes or escape characters. This happens in Excel 2003 and Excel 2007.

  • Detect the URI encoding automatically in Tomcat

    - by Roland Illig
    I have an instance of Apache Tomcat 6.x running, and I want it to interpret the character set of incoming URLs a little more intelligent than the default behavior. In particular, I want to achieve the following mapping: So%DFe => Soße So%C3%9Fe => Soße So%DF%C3%9F => (error) The bevavior I want could be described as "try to decode the byte stream as UTF-8, and if it doesn't work assume ISO-8859-1". Simply using the URIEncoding configuration doesn't work in that case. So how can I configure Tomcat to encode the request the way I want? I might have to write a Filter that takes the request (especially the query string) and re-encodes it into the parameters. Would that be the natural way?

  • Hidden features of CSS

    - by alex
    I have definitely picked up some useful tips in the hidden features style questions concerning PHP and XHTML. So here is one to cover CSS. While easy to pick up, it takes a little while to learn about everything, their default behaviors, properties etc Here are some to start the ball @charset "UTF-8"; /* set the character set. must be first line as Gumbo points out in comments */ .element { /* takes precedence over other stylings */ display: block !important; /* mozilla .... rounded corners with no images */ -moz-border-radius: 10px; /* webkit equivalent */ -webkit-border-radius: 10px } These are not so much hidden, but their use is not often widespread. What tips, tricks, rare features have you discovered with CSS?

  • cgi.FieldStorage translating unicode strangely

    - by trydyingtolive
    I have a form that is on a UTF-8 encoded page. When I submit the form cgi.FieldStorage converts any non-ascii character to an odd format. For example if I submit the value c. The browser will send %c4%87. I want to convert that to the string \xc4\x87. However, cgi.FieldStorage is converting it to \\xc4\\x87. post = cgi.FieldStorage(fp=env['wsgi.input'], environ=env, keep_blank_values=True) Python 2.6 on Ubuntu 9.10SE, Apache2, mod_wsgi.

  • How to access pixels of an NSBitmapImageRep?

    - by Paperflyer
    I have an NSBitmapImageRep that is created like this: NSBitmapImageRep *imageRep = [[NSBitmapImageRep alloc] initWithBitmapDataPlanes:NULL pixelsWide:waveformSize.width pixelsHigh:waveformSize.height bitsPerSample:8 samplesPerPixel:4 hasAlpha:YES isPlanar:YES colorSpaceName:NSCalibratedRGBColorSpace bytesPerRow:0 bitsPerPixel:0]; Now I want to access the pixel data so I get a pointer to the pixel planes using unsigned char *bitmapData; [imageRep getBitmapDataPlanes:&bitmapData]; According to the Documentation this returns a C array of five character pointers. But how can it do that? since the type of the argument is unsigned char **, it can only return an array of chars, but not an array of char pointers. So, this leaves me wondering how to access the individual pixels. Do you have an idea how to do that? (I know there is the method – setColor:atX:y:, but it seems to be pretty slow if invoked for every single pixel of a big bitmap.)

  • Which is the correct shorthand - "regex" or "regexp".

    - by Vilx-
    Most of us computer programmers are pretty obsessed about correct terminology. I certainly am, especially because sometimes changing just one character in a word can drastically change its meaning. So... what is the correct shorthand for "regular expression"? Is it "regex" or "regexp"? On the internet I see both uses, although "regex" seems to be more popular, and the tag list here on SO also includes just "regex". But plenty of people also use "regexp" in their questions.

  • what architecture for implementing a richtext editor?

    - by genesys
    Hi! Can someone give me some hints on how a clean implementation (designwise) of a richtext editor could look like that allows for things like setting fonts, setting character colors and so on? And when and how are characters rendered? are characters rendered only once and the bitmap representation is cached? Is there any article or book covering what software design would be appropriate for that? background is that we're working on a text editing software for a language that cannot be displayed with unicode any hint is appreciated! thanks!

  • Java NIO SocketChannel writing problem

    - by Nilesh
    I am using Java NIO's SocketChannel to write : int n = socketChannel.write(byteBuffer); Most of the times the data is sent in one or two parts; i.e. if the data could not be sent in one attemmpt, remaining data is retried. The issue here is, sometimes, the data is not being sent completely in one attempt, rest of the data when tried to send multiple times, it occurs that even after trying several times, not a single character is being written to channel, finally after some time the remaning data is sent. What could be the cause of such behaviour? Could external factors such as RAM, etc cause the hindarance? Please help me solve this issue. If any other information is required please let me know. Thanks

  • how to prevent white spaces in a regular expression regex validation

    - by Rees
    i am completely new to regular expressions and am trying to create a regular expression in flex for a validation. using a regular expression, i am going to validate that the user input does NOT contain any white-space and consists of only characters and digits... starting with digit. so far i have: expression="[A-Za-z][A-Za-z0-9]*" this correctly checks for user input to start with a character followed by a possible digit, but this does not check if there is white space...(in my tests if user input has a space this input will pass through validation - this is not desired) can someone tell me how i can modify this expression to ensure that user input with whitespace is flagged as invalid?

  • C++/CLI .ToString() returning error

    - by George Johnston
    I am a beginner to C++/CLI as I come from a C# background. I am currently writing a wrapper for some native C++ code. I have the following methods: void AddToBlockList(System::String^ address) { char* cAddress = (char*)(void*)Marshal::StringToHGlobalAnsi(address); _packetFilter->AddToBlockList(cAddress); } void AddToBlockList(IPAddress^ address) { char* cAddress = (char*)(void*)Marshal::StringToHGlobalAnsi(address.ToString()); _packetFilter->AddToBlockList(cAddress); } ...The first method works fine and converts my string into the character array. However, the second function with the IPAddress object as the signiture gives me the following error: error C2228: left of '.ToString' must have class/struct/union ...When I type ? address.ToString() ...in the command window, the IP Address prints. Not sure where I'm going wrong. Any ideas?

  • django 'urlize' strings form tect just like twitter

    - by dana
    heyy there i want to parse a text,let's name it 'post', and 'urlize' some strings if they contain a particular character, in a particular position. my 'pseudocode' trial would look like that: def urlize(post) for string in post if string icontains ('#') url=(r'^searchn/$', searchn, name='news_searchn'), then apply url to the string return urlize(post) i want the function to return to me the post with the urlized strings, where necessary (just like twitter does). i don't understand: how can i parse a text, and search for certain strings? is there ok to make a function especially for 'urlizing' some strings? The function should return the entire post, no matter if it has such kind of strings. is there another way Django offers? Thank you

  • Exception design: Custom exceptions reading data from file?

    - by User
    I have a method that reads data from a comma separated text file and constructs a list of entity objects, let's say customers. So it reads for example, Name Age Weight Then I take these data objects and pass them to a business layer that saves them to a database. Now the data in this file might be invalid, so I'm trying to figure out the best error handling design. For example, the text file might have character data in the Age field. Now my question is, should I throw an exception such as InvalidAgeException from the method reading the file data? And suppose there is length restriction on the Name field, so if the length is greater than max characters do I throw a NameTooLongException or just an InvalidNameException, or do I just accept it and wait until the business layer gets a hold of it and throw exceptions from there? (If you can point me to a good resource that would be good too)

  • Getting the Value of a UITextField as keystrokes are entered?

    - by Nocturne
    Let's say I have the following code: IBOutlet UITextField* nameTextField; IBOutlet UILabel* greetingLabel; I'd like the greetingLabel to read "Hello [nameTextField]" as soon as the user presses any key. What I need basically is the iPhone equivalent of the Cocoa delegate method -controlTextDidChange: The -textField:shouldChangeCharactersInRange: delegate method is called each time a keystroke occurs: - (BOOL) textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string The string argument returns the character that is pressed. The actual textField's value (nameTextField.text) remains blank however. What am I missing here? (I'd like nameTextField to reflect the exact string that the user has entered so far)

  • Where is the Android Metamodel located?

    - by Dominik
    Hey, I would like to use Android for Model-Driven-Software-Development. For this, I need to locate the Android Model in the SDK. I already searched a while for it, but were not able to find it. Has anyone an idea where it could be? Is it possible, that it is the AndroidManifest.xml-File in the folder android-sdk-\platforms\android-x\android.jar? After unpacking this file, I am not able to open that file correctly on Windows XP, because a lot of characters have the wrong character set. Or is it also possible, that it is only located in the source code? Thanks in advance, Dominik

  • How to write to the OpenGL Depth Buffer

    - by Mikepote
    I'm trying to implement an old-school technique where a rendered background image AND preset depth information is used to occlude other objects in the scene. So for instance if you have a picture of a room with some wires hanging from the ceiling in the foreground, these are given a shallow depth value in the depthmap, and when rendered correctly, allows the character to walk "behind" the wires but in front of other objects in the room. So far I've tried creating a depth texture using: glTexImage2D(GL_TEXTURE_2D, 0, GL_DEPTH_COMPONENT, Image.GetWidth(), Image.GetHeight(), 0, GL_DEPTH_COMPONENT, GL_UNSIGNED_BYTE, pixels); Then just binding it to a quad and rendering that over the screen, but it doesnt write the depth values from the texture. I've also tried: glDrawPixels(Image.GetWidth(), Image.GetHeight(), GL_DEPTH_COMPONENT, GL_UNSIGNED_BYTE, pixels); But this slows down my framerate to about 0.25 fps... I know that you can do this in a pixelshader by setting the gl_fragDepth to a value from the texture, but I wanted to know if I could achieve this with non-pixelshader enabled hardware?

  • How to use Unicode characters in a vim script?

I'd hoped the following would work: if has("multi_byte") set lcs=tab:? else set lcs=tab:>- endif However, this gives me E474: Invalid argument: lcs=tab:? The file is UTF-8 encoded and includes a BOM. Googling "vim encoding" or similar gives me many results about the encoding of edited files, but nothing about the encoding of executed scripts. How to get this character into my .vimrc so that it is properly displayed?
