  • PDF Report generation

    - by IniTech
    EDIT : I completed this project using ABCpdf. For anyone interested, I love this product and their support is A+. Everything I listed as a 'Con' for the HTML - PDF solution was easily doable in ABCpdf. I've been charged with creating a data driven pdf report. After reviewing the plethora of options, I have narrowed it down to 2. I need you all to to help me decide, or offer alternatives I haven't considered. Here are the requirements: 100% Data driven Eventually PDF (a stop in HTML is fine, so long as it is converted) Can be run with multiple sets of data (the layout is always the same, the data is variable) Contains normal analysis-style copy (saved in DB with html markup) Contains tables (data for tables is generated at run-time) Header/Page # on each page Table of Contents .NET (VB or C#) Done quickly Now, because of the fact that the report is going to be generated with multiple sets of data, I don't think a stamped pdf template will work since I won't know how long or how many pages a certain piece of the report could require. So, I think my best options are: Programmatic creation using an iText-like solution. Generate in HTML and convert to PDF using a third-party application (ABCPdf is the tool I have played with so far) Both solutions have their pro's and con's. Programmatic solution: Pros: Flexible Easy page numbering/page header/table of contents Free Cons: Time consuming (to write a layer on top of iText to do what I need and keep maintainable) Since the copy is already stored in the db with html markup, I would have to parse through the data before I place it into the pdf, ensuring I don't have to break the paragraph into chunks so I can apply bold, italic, underline, etc. to specific phrases. This seems like a huge PITA, and I hope I am wrong about that assumption. HTML - PDF Pros: Easy to generate from db (no parsing necessary) Many tools for conversion Uses technology I am already familiar with Built-in "Print Preview" - not a req, but nice Cons: (Edited after project completion. All of my assumptions were incorrect and ABCpdf is awesome) 1. Almost impossible to generate page headers - Not True 2. Very difficult to generate page numbers Not True 3. Nearly impossible to generate table of contents Not True 4. (Cross-browser support isn't a con; Since its internal, I can dictate what browser to use) 5. Conversion tool quirks - may not convert exactly as rendered in browser Not True 6. Overall, I think it would be very hard to format the HTML exactly as I would want it to appear/convert to PDF. Not True That's it - I need the communitys help in deciding which way I should go. I might be wrong about some of my Pro/Con assumptions. If I am, please tell me. All thoughts and suggestions are welcome and appreciated. Thanks

  • Stream/string/bytearray transformations in Python 3

    - by Craig McQueen
    Python 3 cleans up Python's handling of Unicode strings. I assume as part of this effort, the codecs in Python 3 have become more restrictive, according to the Python 3 documentation compared to the Python 2 documentation. For example, codecs that conceptually convert a bytestream to a different form of bytestream have been removed: base64_codec bz2_codec hex_codec And codecs that conceptually convert Unicode to a different form of Unicode have also been removed (in Python 2 it actually went between Unicode and bytestream, but conceptually it's really Unicode to Unicode I reckon): rot_13 My main question is, what is the "right way" in Python 3 to do what these removed codecs used to do? They're not codecs in the strict sense, but "transformations". But the interface and implementation would be very similar to codecs. I don't care about rot_13, but I'm interested to know what would be the "best way" to implement a transformation of line ending styles (Unix line endings vs Windows line endings) which should really be a Unicode-to-Unicode transformation done before encoding to byte stream, especially when UTF-16 is being used, as discussed this other SO question.

  • ASP.NET Deploying websites

    - by Bridget
    I have some websites that use ImageMagick to convert images and place them in a created folder. Locally it all worked fine, but once I deployed it to my network's webserver it would not convert the images nor create the folders. My asp.net pages that read data from a database work. All the users have full control permissions over the site. I don't know if I need to modify the Web.config or some other permissions. Maybe it has to do with ImageMagick. I've just run out of ideas on what the problem could even POSSIBLY be. Any suggestions?

  • converting GPS latitude/longitude from different formats to one format (in PHP)

    - by Dave
    Hi. i'm trying to built in support for locations in my application and i'm expecting users to be inputting gps coordinates in a variety of ways. I need to convert all of the below to: latitude - direction (N/s), degres, minutes, seconds; longitude (E/W) - degrees, minuts, seconds. Each user input will be in a single line. eg: 9.182, -39.140625 9.182 / -39.140625 9.182,-39.140625 9.182 -39.140625 21° 16' 674S[some_separator]27° 30' 318E 21 16 674S[some_separator]27 30 318E [some_separator] may be a single space as well... The final format needs to beas: latitude.direction = south latitude.degrees = 21 latitude.minutes = 16 latitude.seconds = 674 longitude.direction = east longitude.degrees = 27 longitude.minutes = 30 longitude.seconds = 318 (a) what is the simplest way of asking ordinary-non-tech users to input the GPS coordinate?s (b) how do i convert the above to the final format? any built in functions that handle these variations in data input? i've seen http://stackoverflow.com/questions/2548943/gps-format-in-php - but i need to handle a more varied input.

  • WPF Animate a Maxtrix using interpolation

    - by Mark
    Im having a issue with my application that is using touch gestures to scale, translate and rotate my scene. I was using a TransformGroup which contained TranslateTransform, ScaleTransform and a RotateTransform but I could not get the movement correct, it always jumps and skips, so I moved to a MaxtrixTransform which I was able to use much easier to get my scene to be zoomable, rotatable and panable nicely. However, what I later found out was that you cannot animate smoothly (using interpolation) the values of a Matrix, for what reason I have no idea, but its part of the MSDN doco and the properties of the Matrix are not dependency properties anyways... Has anyone had any luck animating a maxtrix to make it smooth? The only idea(s) I have had is to animate a few different, custom DP which all have callbacks that I update the Matrix from OR To convert the Maxtix to a set of Transform object that I then animate and then afterwords convert back. Is there a smarter way to do this?

  • How can an animator do animation targeted for the iPhone

    - by teepusink
    Hi, I'm working with an animator for the iPhone. The animator I'm working with isn't a programmer and has a background in Flash. (right now she's doing the animation in Flash and I need to convert to Objective C). For some it's ok because I can just use image frames, but there are more complex animation that would take longer for me to convert to Objective C. Is there any tools out there that can help the work flow easier? Just trying to find a way so I can just take the animation and stick it into the project. Thanks, Tee

  • I'm mplement http live streaming video from my webserver to iPhone. Will I get rejected for bandwid

    - by yujean
    Apache webserver setup added: AddType application/x-mpegURL .m3u8 AddType video/MP2T .ts to "httpd.conf" file. Movie file preparation I have 3 movie files (9mb - 25mb each). Used QuickTime to convert movies into iPhone format. Used mediafilesegmenter to convert .m4v into 10-second segments of .ts files, with an accompanying .m3u8 file. Placed these in a folder on webserver. iPhone App implementation Created UIWebView whose URL points to http://71.191.59.68/~yujean/stream.html Simulator accesses the site and streams the movie-files just fine. Question Will I still get rejected by apple for bandwidth issues over the 3G and/or Edge network? Do I need to somehow check which network the end-user is on first? And then provide a different movie accordingly? If so, how do I do that ...? Thank you in advance, Eugene

  • Does a PHP library exist to work with PRC/.mobi files?

    - by Chris Clarke
    I'm writing a WordPress plugin to create an eBook from a selected category in most major eBook formats. I would like to support MobiPocket since that's the format used by the Kindle but I'm not sure how to go about it. From what I've read .mobi files are actually Palm Resource Databases (PRC) but I haven't been able to find a PHP class to work with these. I thought about using exec along with KindleGen but that would be undesirable as it would complicate initial setup. I've also thought about hosting a web service somewhere and using XML-RPC to accomplish this but that also complicates things. My question is: is there a PHP class/library (PHP-only preferred) that can work with PRC or even better, a class that specialises in creating MobiPocket ebooks? (needs to be open source since I'm releasing under the GPL) I've tried searching but haven't been able to find anything.

  • C / JSON Library in popular Linux distros?

    - by Tim Post
    I have a program written in C that has to input and output JSON over a local domain socket. I've found several C / JSON libraries that 'almost work' through searches. Prior to taking one of the libraries that I found .. I want to be sure that I'm not over-looking a library that is commonly found on modern Linux distros. I'd also really appreciate links to libraries that you use. Most likely, I'll just drop it in tree, unless I realize that I've over looked something widely distributed. I am tagging this as subjective because the answer that I select is the one linking to a library that works for me, that does not mean its the 'best' library. I want to take an existing array and easily convert it to a buffer that can be sent, or take a buffer and easily convert it into an allocated array. Thanks in advance!

  • Converting datetime.ctime() values to Unicode

    - by Malcolm
    I would like to convert datetime.ctime() values to Unicode. Using Python 2.6.4 running under Windows I can set my locale to Spanish like below: import locale locale.setlocale(locale.LC_ALL, 'esp' ) Then I can pass %a, %A, %b, and %B to ctime() to get day and month names and abbreviations. import datetime dateValue = datetime.date( 2010, 5, 15 ) dayName = dateValue.strftime( '%A' ) dayName 's\xe1bado' How do I convert the 's\xe1bado' value to Unicode? Specifically what encoding do I use? I'm thinking I might do something like the following, but I'm not sure this is the right approach. codePage = locale.getdefaultlocale()[ 1 ] dayNameUnicode = unicode( dayName, codePage ) dayNameUnicode u's\xe1bado' Malcolm

  • Why '.png' files produced by ImageMagick are so much bigger than '.jpg' & '.gif' files?

    - by Nick Gorbikoff
    Hello. I'm using ImageMagick to convert some files from one format to another. I was always under the impression that .png files were supposed to be as big/small as .jpg if not smaller, and definitely smaller than .gif. However when I run convert photo.jpg photo.png The files I'm getting out is about 6 times bigger than the original jpg. Original jpg is a regular photo about 300x500 px, 52 kb. Output is a proper png of the same dimensions, but size is about 307 kb? Does anyoone know what the hack is going on? Am I doing something wrong? P.S.: I tried both on Debian and Windows with the same results.

  • Converting BMPs to avi

    - by Lucas
    I want to convert folders with video-frames in bitmaps into avi or mpeg files. I already have a VBScript which does a lot of stuff on those files, so it would be neat to integrate a functionallity to convert those folders automatically from my script. I can only find solutions that seem pretty low level and unfortunatley I don't know a whole lot about video file formats. What is the easiest approach to achieve that without reinventing the wheel? My problem is that there is seem to be so much information that I am not sure where to start.

  • Compressing a hex string in Ruby/Rails

    - by PreciousBodilyFluids
    I'm using MongoDB as a backend for a Rails app I'm building. Mongo, by default, generates 24-character hexadecimal ids for its records to make sharding easier, so my URLs wind up looking like: example.com/companies/4b3fc1400de0690bf2000001/employees/4b3ea6e30de0691552000001 Which is not very pretty. I'd like to stick to the Rails url conventions, but also leave these ids as they are in the database. I think a happy compromise would be to compress these hex ids to shorter collections using more characters, so they'd look something like: example.com/companies/3ewqkvr5nj/employees/9srbsjlb2r Then in my controller I'd reverse the compression, get the original hex id and use that to look up the record. My question is, what's the best way to convert these ids back and forth? I'd of course want them to be as short as possible, but also url-safe and simple to convert. Thanks!

  • Beginner Java Question about Integer.parseInt() and casting

    - by happysoul
    so when casting like in the statement below :- int randomNumber=(int) (Math.random()*5) it causes the random no. generated to get converted into an int.. Also there's this method I just came across Integer.parseInt() which does the same ! i.e return an integer Why two different ways to make a value an int ? Also I made a search and it says parseInt() takes string as an argument.. So does this mean that parseInt() is ONLY to convert String into integer ? What about this casting then (int) ?? Can we use this to convert a string to an int too ? sorry if it sounds like a dumb question..I am just confused and trying to understand Help ?

  • markdown to HTML with customised WMD editor

    - by spirytus
    For my application I customized slightly the way WMD behaves so when user enters empty lines, these are reflected in HTML output as <br />'s. Now I came to a point when I should store it somewhere at backend and so after going thru SO posts for a while I'm not sure what is the best way to do it. I have few options and if you could point out which their pros/cons that would be much appreciated. send to server and store as markdown rather than HTML. To me obvious advantage would be keeping exactly same formatting as user originally entered. But then how can I convert it back to HTML for display to a client? It seems very troublesome to convert it on client side as even if it would be possible what would happen if JS would be disabled? If I wanted to do it on the server, then standard server side implementations of markup to HTML might be resource expensive. Would that be an issue in your opinion? Even if it wouldn't be the case then as I mentioned my WMD implementation is customised and those server side solutions wouldn't probably do the right conversion to markdown anyway and there always would be a risk that something would convert wrong. Send to server as converted HTML. Same as above.. conversion on client side would be difficult, server side same with possibility of getting it wrong. send original markdown and converted HTML and store both. No performance issues related to converting markdown to HTML on client side, nor on server side. Users would have always same markdown they originally entered and same HTML they originally saw in preview (possibly sanitized in php though). It would have to take twice that much storage space though and that is my biggest worry. I tend to lean towards 3rd solution as it seems simplest, but there is a worry of doubled storage space needed for this solution. Please bear in mind that my implementation of WMD is slightly modified and also I'm going with PHP/MySql server side implementation. So apart from 3 options I listed above, are there any other possible solutions to my problem? Did I miss anything important that would make one of the options above better then the rest? And what other pros/cons would apply to each solution I listed? Also how is it implemented on SO? I read somwhere that they using option 3, and so if its good enough for SO would be good enough for me :) but not sure if its true anyway, so how is it done? Also please forgive me, but at least for once I got to say that StackOverflow IS THE BEST DAMN RESOURCE ON THE WEB and I truly appreciate all the people trying to help others here! The site and users here are simply amazing!

But after executing I'm getting: org.hibernate.QueryException: Not all named parameters have been set: [:TEXT] [select * from news WHERE lower(ID::TEXT) LIKE '%5%' Exception. Looks like hibernate parse my convert exp as parameter. Any help is appreciated. Thanks.
