  • PhantomJS not exactly rendering HTML to PNG

    - by John Leonard
    I'm having trouble adjusting PhantomJS to create a PNG file that matches the original browser presentation. Here is the entire sample html file. It's a sankey diagram creating using rCharts and d3-sankey. (You'll need to save the file to your hard drive and view it from there.) I'm running on Windows and using rasterize.js: >> phantomjs.exe rasterize.js test.html test.png ISSUE: Below is a snip of one of the text strings when viewed in a browser: And here is a snip of the same string from the PNG created by PhantomJS: How do I make the text-shadow go away? I've played around with various CSS attributes (text-shadow) and webkit-specific attributes (e.g., -webkit-text-rendering), but can't seem to make it go away. Is this a setting in PhantomJS? in the underlying webkit? or somewhere else? Many thanks!

  • Nested table height in TCPDF

    - by Kuroki Kaze
    Is it possible to make nested table fit height of its parent cell in TCPDF? My code: <?php require_once('tcpdf/config/lang/eng.php'); require_once('tcpdf/tcpdf.php'); $pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false); $pdf->setPrintHeader(false); $pdf->setPrintFooter(false); $pdf->SetFont('times', 'BI', 8); $pdf->AddPage(); $pdf->writeHTML('<table> <tr><td bgcolor="gray"> Angoisse et vif espoir, sans humeur factieuse.<br/> Plus allait se vidant le fatal sablier,<br/> Plus ma torture était âpre et délicieuse;<br/> Tout mon coeur s’arrachait au monde familier</td> <td bgcolor="lightgray">Second</td> <td bgcolor="gray">Third</td> <td> <table style="height: 100%"> <tr bgcolor="blue" style="height: 30%"><td bgcolor="yellow" style="height: 30%">Ichi</td></tr> <tr bgcolor="white" style="height: 30%"><td bgcolor="cyan" style="height: 30%">Ni</td></tr> <tr bgcolor="blue" style="height: 30%"><td bgcolor="yellow" style="height: 30%">San</td></tr> </table> </td></tr> </table>'); $pdf->Output('example_002.pdf', 'I'); ?> I want table in last cell to fill it entirely. Is there any way to do this?

  • Programmatically implementing an interface that combines some instances of the same interface in var

    - by namin
    What is the best way to implement an interface that combines some instances of the same interface in various specified ways? I need to do this for multiple interfaces and I want to minimize the boilerplate and still achieve good efficiency, because I need this for a critical production system. Here is a sketch of the problem. Abstractly, I have a generic combiner class which takes the instances and specify the various combinators: class Combiner<I> { I[] instances; <T> T combineSomeWay(InstanceMethod<I,T> method) { // ... method.call(instances[i]) ... combined in some way ... } // more combinators } Now, let's say I want to implement the following interface among many others: Interface Foo { String bar(int baz); } I want to end up with code like this: class FooCombiner implements Foo { Combiner<Foo> combiner; @Override public String bar(final int baz) { return combiner.combineSomeWay(new InstanceMethod<Foo, String> { @Override public call(Foo instance) { return instance.bar(baz); } }); } } Now, this can quickly get long and winded if the interfaces have lots of methods. I know I could use a dynamic proxy from the Java reflection API to implement such interfaces, but method access via reflection is hundred times slower. So what are the alternatives to boilerplate and reflection in this case?

  • jQuery Validation rule inner HTML

    - by Sam Zhou
    As we know, jquery.validation.js is very powerful. In common, we should define the rule in js first, and then apply to input element or form. I'd like to declare the rule inner HTML code, then validator to find and apply the rule. just as below: <input MaxLength="10" id="StrField" class="required" name="StrField" type="text" value="Test" /> I have used to rules: required MaxLength My question is all the rules in jquery.validation could be wrote in HTML tag using attribute, and where I could get the document? can the jquery.metadata help for this?

  • Compact representation of GUID/UUID?

    - by chakrit
    I need to generate a GUID and save it via a string representation. The string representation should be as short as possible as it will be used as part of an already-long URL string. Right now, instead of using the normal abcd-efgh-... representation, I use the raw bytes generated and base64-encode them instead, which results in a somewhat shorter string. But is it possible to make it even shorter? I'm OK with losing some degree of uniqueness and keeping a counter, but scanning all existing keys is not an option. Suggestions?

  • XML to DOC to PDF

    - by Max
    what is the easiest(and fastest) way to perform this kind of transformation: "Data in XML" to "Some MS Word 2003 Supported format" to PDF using Java? My first guess was to fill the template with XML data (using Placeholders for example) and then save it and convert it to PDF. But I can't just put placeholders to DOC files, and I can't convert from some other Word formats to PDF... My primary task is to convert XML Data to PDF allowing users to change the PDF on-demand. The best way to change the PDF on-demand seems to give user some kind of MS Word readable document, and then convert it back. There are 2 main problems with this task: 1) I can't use OpenOffice for conversion. 2) System should be able to convert ~1 page of table-based document per 1 second on 2Ghz Core. 3) RTF does not provide enough styling, so some more complex format should be used. Thanks in advance.

  • Html.RenderAction<MyController> - does not have type parameters

    - by Ami
    Hi, I'm trying to use RenderAction in the following way: '<% Html.RenderAction( x = x.ControllerAction() ); %' as seen here: http://devlicio.us/blogs/derik_whittaker/archive/2008/11/24/renderpartial-vs-renderaction.aspx and here: http://eduncan911.com/blog/html-renderaction-for-asp-net-mvc-1-0.aspx but I keep getting an error about the method not having type parameters. also in MSDN I see there is no documentation for it, and also checking the MVC source code I can't find anything. I'm using the latest ASP.Net MVC (2.0 RTM) is this feature no longer available? how can I use it? thanks.

  • svcutil, WSDL, and the generated interfaces not being sufficient for implementation

    - by chtmd
    I have a WSDL file defining a service that I have to implement in WCF. I had read that I could generate the proxy using svcutil from the WSDL file, and that I could then use the generated interfaces to implement the service. Unfortunately, I can't quite seem to find a way to have the interfaces contain the correct attributes to expose the contracts. All operations have the "OperationContractAttribute" attribute, but it appears as though for the service to be exposed, I require the "OperationContract" for each one. Same thing with "ServiceContractAttribute" and "ServiceContract", and I imagine DataContract, but I haven't gotten that far. I could manually make these changes, but I would much prefer a technique where the existing code could be easily used, or better code could be generated for my uses. Is there some way that this can be done? Thanks. EDIT: Command used: svcutil ObjectManagerService.wsdl /n:*,Sample /o:ObjectManagerServiceProxy.cs /nologo Code sample: public interface ObjectManagerSyncPortType { // CODEGEN: Generating message contract since the operation createObject is neither RPC nor document wrapped. [System.ServiceModel.OperationContractAttribute(Action="http://www.sample.com/createObject", ReplyAction="*")] [System.ServiceModel.XmlSerializerFormatAttribute()] Sample.createObjectResponse1 createObject(Sample.createObjectRequest1 request); As best as I can tell/see the WSDL file is entirely self-contained and requires no additional XSD files.

  • Creating a multi-page PDF doc

    - by codemercenary
    Hi, has anyone already created a PDF document in an iPad app. i see that there are new functions in the UIKit to do this, but I can't find any code example for this. BOOL UIGraphicsBeginPDFContextToFile ( NSString *path, CGRect bounds, NSDictionary *documentInfo ); void UIGraphicsBeginPDFPage ( void ); I found an example that is supposed to work on the iPhone, but this gives me errors: Fri Apr 30 11:55:32 wks104.hs.local PDF[1963] <Error>: CGFont/Freetype: The function `create_subset' is currently unimplemented. Fri Apr 30 11:55:32 wks104.hs.local PDF[1963] <Error>: invalid Type1 font: unable to stream font. Fri Apr 30 11:55:32 wks104.hs.local PDF[1963] <Error>: FT_Load_Glyph failed: error 6.

  • Adding text over existing PDFs using reportlab

    - by Shane
    I'm interested in filling out existing PDF forms programatically. All I really need to do is pull information from user input and then place the appropriate text over an existing PDF in the appropriate locations. I can already do this with reportlab by feeding the same sheet of paper into a printer, twice, but this just really rubs me the wrong way. I'm tempted to just personally reverse engineer each existing PDF and draw every line and character myself before adding the user-inputted text, but I wanted to check to see if there was an easy way to take an existing PDF and set it as a background for some extra text. I'd really prefer to use python as it's the only language I feel comfortable with. I also realize that I could just scan the document itself and use the resulting raster image as a background, but I would prefer the precision of vector graphics. It seems like ReportLab has a commercial product with this functionality, and the specific function I'm looking for is in it (copyPages) - but it seems like overkill to pay for a 4 figure product for a single, simple function for a nonprofit use.

  • x86 instruction encoding tables

    - by Cheery
    I'm in middle of rewriting my assembler. While at it I'm curious about implementing disassembly as well. I want to make it simple and compact, and there's concepts I can exploit while doing so. It is possible to determine rest of the x86 instruction encoding from opcode (maybe prefix bytes are required too, a bit). I know many people have written tables for doing it. I'm not interested about mnemonics but instruction encoding, because it is an actual hard problem there. For each opcode number I need to know: does this instruction contain modrm? how many immediate fields does this instruction have? what encoding does an immediate use? is the immediate in field an instruction pointer -relative address? what kind of registers does the modrm use for operand and register fields? sandpile.org has somewhat quite much what I'd need, but it's in format that isn't easy to parse. Before I start writing and validating those tables myself, I decided to write this question. Do you know about this kind of tables existing somewhere? In a form that doesn't require too much effort to parse.

  • How to keep unreachable code?

    - by Gabriel
    I'd like to write a function that would have some optional code to execute or not depending on user settings. The function is cpu-intensive and having ifs in it would be slow since the branch predictor is not that good. My idea is making a copy in memory of the function and replace NOPs with jumps when I don't want to execute some code. My working example goes like this: int Test() { int x = 2; for (int i=0 ; i<10 ; i++) { x *= 2; __asm {NOP}; // to skip it replace this __asm {NOP}; // by JMP 2 (after the goto) x *= 2; // Op to skip or not x *= 2; } return x; } In my test's main, I copy this function into a newly allocated executable memory and replace the NOPs by a JMP 2 so that the following x *= 2 is not executed. The problem is that I would have to change the JMP operand every time I change the code to be skipped. An alternative that would fix this problem would be: __asm {NOP}; // to skip it replace this __asm {NOP}; // by JMP 2 (after the goto) goto dont_do_it; x *= 2; // Op to skip or not dont_do_it: x *= 2; This way, as a goto uses 2 bytes of binary, I would be able to replace the NOPs by a fixed JMP of alway 2 in order to skip the goto. Unfortunately, in full optimization mode, the goto and the x*=2 are removed because they are unreachable at compilation time. Hence the need to keep that dead code.

  • I want to merge two PostScript Documents, pagewise. How?

    - by Peter Miehle
    hello, i have a tricky question, so i need to describe my problem: i need to print 2-sided booklets (a third of a paper) on normal paper (german A4, but letter is okay also) and cut the paper afterwards. The Pages are in a Postscript Level 2 File (generated by an ancient printer driver, so no chance to patch that, except ps2ps) generated by me with the ancient OS's Printing driver facilities (GpiMove, GpiLine, GpiText etc). I do not want to throw away two-thirds of the paper, so my idea is: Take file one, two and three, merge them (how?) on new double-sided papers by translate/move file two and three by one resp. two thirds and print the resulting new pages. If it helps, I can manage to print one page of the booklet per file. I cannot "speak" postscript natively, but I am capable of parsing and merging and manipulating files programmaticly. Maybe you can hint me to a webpage. I've read through the manuals on adobe's site and followed the links on www.inkguides.com/postscript.asp Maybe there are techniques with PDF that would help? I can translate ps2pdf. Thanks for help Peter Miehle PS: my current solution: i.e. 8 pages: print page 1, 4 and 7 on page one, 2,5,8 on page two and 3,6,blank on page three, cut the paper and restack. But i want to use a electrical cutting machine, which works better with thicker stacks of paper.

  • C# WebClient only downloads partial html

    - by H4mm3rHead
    Hi, I am working on some scraping app, i wanted to try to get it to work but ran into a problem. I have replaced the original scraping destination in the below code with googles webpage, just for testing. It seems that my download doesnt get everything, i note that the body and the html tags are missing their close tags. How do i get it to download everything? Whats wrong with my sample code: string filename = "test.html"; WebClient client = new WebClient(); string searchTerm = HttpUtility.UrlEncode(textBox2.Text); client.QueryString.Add("q", searchTerm); client.QueryString.Add("hl", "en"); string data = client.DownloadString("http://www.google.com/search"); StreamWriter writer = new StreamWriter(filename, false, Encoding.Unicode); writer.Write(data); writer.Flush(); writer.Close();

  • Need to merge multiple pdf's into a single PDF with Table Of Contents sections

    - by Jason
    Will have 50-100 single PDF's that we'll be generating with a php script. PDF's are generally grouped into groups of 10-20. Each group needs to have it's own Table of Contents or Index, and then there also needs to be a Master Table of Contents or Index at the beginning. Or if that is too difficult we could get away with a single Table of Contents at the beginning. What's the best way to go about this? Will we need to create the Table of Contents and then export that to PDF and append it to the beginning and mash the rest of the files after that? Or is there a better solution? And what's the best tool for us to merge the pdf's? Will be running on a Linux server.

  • How can I get PowerShell Added-Types to use Added References

    - by Scott Weinstein
    I'm working on a PoSh project that generates CSharp code, and then Add-Types it into memory. The new types use existing types in an on disk DLL, which is loaded via Add-Type. All is well and good untill I actualy try to invoke methods on the new types. Here's an example of what I'm doing: $PWD = "." rm -Force $PWD\TestClassOne* $code = " namespace TEST{ public class TestClassOne { public int DoNothing() { return 1; } } }" $code | Out-File tcone.cs Add-Type -OutputAssembly $PWD\TestClassOne.dll -OutputType Library -Path $PWD\tcone.cs Add-Type -Path $PWD\TestClassOne.dll $a = New-Object TEST.TestClassOne "Using TestClassOne" $a.DoNothing() "Compiling TestClassTwo" Add-Type -Language CSharpVersion3 -TypeDefinition " namespace TEST{ public class TestClassTwo { public int CallTestClassOne() { var a = new TEST.TestClassOne(); return a.DoNothing(); } } }" -ReferencedAssemblies $PWD\TestClassOne.dll "OK" $b = New-Object TEST.TestClassTwo "Using TestClassTwo" $b.CallTestClassOne() Running the above script gives the following error on the last line: Exception calling "CallTestClassOne" with "0" argument(s): "Could not load file or assembly 'TestClassOne,...' or one of its dependencies. The system cannot find the file specified." At AddTypeTest.ps1:39 char:20 + $b.CallTestClassOne <<<< () + CategoryInfo : NotSpecified: (:) [], MethodInvocationException + FullyQualifiedErrorId : DotNetMethodException What am I doing wrong?
