  • Wider than expected margins with CGContextDrawPDFPage

    - by skantner
    I'm rendering PDF pages on iPhone using the code below. It works, but the margins seem much wider than when I view the same PDF using a Acrobat Reader or the Mac's Preview, and that consequently scales the content down much smaller than it otherwise would be. Is my code actually causing this behavior? CGContextSetStrokeColorWithColor(context, backgroundColor.CGColor); CGContextSetFillColorWithColor(context,backgroundColor.CGColor); CGContextSetLineWidth(context, 2.0); CGContextAddRect(context, CGRectMake(0.0,0.0, self.bounds.size.width, self.bounds.size.height)); CGContextDrawPath(context, kCGPathFillStroke); CGContextTranslateCTM(context, 0.0, self.bounds.size.height); CGContextScaleCTM(context, 1.0, -1.0); CGPDFPageRef page = CGPDFDocumentGetPage(myPDF, (size_t) pageNum); CGContextSaveGState(context); CGAffineTransform pdfTransform = CGPDFPageGetDrawingTransform(page, kCGPDFMediaBox, self.bounds, 0, true); CGContextConcatCTM(context, pdfTransform); CGContextDrawPDFPage(context, page); CGContextRestoreGState(context);

  • setAnimationRepeatAutoreverses not behaved as I expected

    - by danielkwan
    I am starting to learn to use UIView animation. So I wrote the following lines: [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:2.0]; [UIView setAnimationRepeatCount:2]; [UIView setAnimationRepeatAutoreverses:YES]; CGPoint position = greenView.center; position.y = position.y + 100.0f; position.x = position.x + 100.0f; greenView.center = position; [UIView commitAnimations]; In this case, the UIView (a green box) moved back and fore 2 times. So far so good, BUT I found out that after the moving twice, the green box ended up jumped to the "new position" (position.x + 100.0f, position.y + 100.0f) instead of going back to the original position (position.x, position.y). That makes the animation look pretty odd (like after the box swing back to the original position caused by setAnimationRepeatAutoreverses, it jumps back to the new position in the last microsecond!) What is the best way to make the green box NOT jump to the new position at the very last minute?

  • Android:Multi touch doesn't work as expected?

    - by user187532
    Hi folks, Help me in resolving the below issue. I have three image buttons on screen. All these three buttons controlled under ontouchlistner as below. buttonOne.setOnTouchListener(this); buttonTwo.setOnTouchListener(this); buttonThree.setOnTouchListener(this); I override "public boolean onTouch(View v, MotionEvent event)". Under this i check for these three image buttons touch events like below. ImageButton imageBtn = (ImageButton) v; if ( imageBtn == buttonOne ) // first button touch ..Log.. else if ( imageBtn == buttonTwo ) ..Log.. else if ( imageBtn == buttonThree ) // first button touch ..Log.. My problem is, as it is under multi touch event handler like above, it does not detect when touch all three button at a time to try to produce multi touch effect, instead it detects only one imagebutton touch at a time even though i touch all three image buttons. As i am developing this project on Android 1.6 SDK, is there any problem accessing my requirement(multi touch) (or) it is a known issue? I am hoping that, when it works for single button touch, why shouldn't it work when clicking three imagebuttons at a time to produce three logs printed as per my above code? How do i resolve it for my case? Please don't question me why i am still developing on 1.6 for such a requirement. Thank you. Appreciate your suggestions !

  • C# yield return not returning an item as expected

    - by Jiho Han
    I have following code: private void ProcessQueue() { foreach (MessageQueueItem item in GetNextQueuedItem()) PerformAction(item); } private IEnumerable<MessageQueueItem> GetNextQueuedItem() { if (_messageQueue.Count > 0) yield return _messageQueue.Dequeue(); } Initially there is one item in the queue as ProcessQueue is called. During PerformAction, I would add more items to _messageQueue. However, the foreach loop quits after the initial item and does not see the subsequent items added. I sense that somehow the initial state of the queue is being captured by yield. Can someone explain what is happening and give a solution?

  • "type" Command Not Working As Expected on Git Bash

    - by trysis
    The type command, in Linux, returns the location, on the filesystem, of the given file, if it is in the current folder or the $PATH. This functionality is also available through Windows with the Git Bash command line program. The command also returns a file's location given the file without its extension (.exe, .vbs, etc.) However, I have run into what seems like a strange corner case where the file exists on the $PATH but doesn't get returned using the command. I am thinking of buying a new computer soon, so I looked up the method of transferring the license key from one computer to another, in preparation for actually doing this. The method I found mentioned the files slmgr.vbs and slui.exe, both of which reside in the C:/Windows\System32 folder, which is in my $PATH, as usual for a Windows computer. However, these two files aren't showing up when I use the type command. Also, neither gets executed when I call the files as commands without their extensions in Git Bash, and only slmgr.vbs gets executed when I call them with the extensions. Finally, slmgr.vbs is shown when listing the folder's contents in Git Bash, as well, but slui.exe isn't. I thought this might have to do with permissions, and, indeed, both files have very restrictive permissions, as you can see in the pictures below, but they both have the same permissions, which wouldn't explain why one gets executed and the other doesn't when called directly, nor why one file is listed on command line but the other isn't. C:\Windows\System32 folder, proving the files exist: File permissions for the Users and Administrators groups for the two files (they are identical): And the folder: type command and its output in Git Bash for the 2 files, plus listing the files in the folder (using grep to filter as the folder is huge), as well as listing part of the $PATH (keep in mind, for all these, that Git Bash changes the paths as they are displayed): Sean@MYPC ~ $ type -a slmgr sh.exe": type: slmgr: not found Sean@MYPC ~ $ type -a slmgr.vbs sh.exe": type: slmgr.vbs: not found Sean@MYPC ~ $ type -a slui sh.exe": type: slui: not found Sean@MYPC ~ $ type -a slui.exe sh.exe": type: slui.exe: not found Sean@MYPC ~ $ slmgr sh.exe": slmgr: command not found Sean@MYPC ~ $ slmgr.vbs /c/WINDOWS/system32/slmgr.vbs: line 2: syntax error near unexpected token `(' /c/WINDOWS/system32/slmgr.vbs: line 2: `' Copyright (c) Microsoft Corporation.

If permissions, why do they seem to have the same permissions, yet both are not handled in the same way?

  • Convert your Hash keys to object properties in Ruby

    - by kerry
    Being a Ruby noob (and having a background in Groovy), I was a little surprised that you can not access hash objects using the dot notation.  I am writing an application that relies heavily on XML and JSON data.  This data will need to be displayed and I would rather use book.author.first_name over book[‘author’][‘first_name’].  A quick search on google yielded this post on the subject. So, taking the DRYOO (Don’t Repeat Yourself Or Others) concept.  I came up with this: 1: class ::Hash 2:  3: # add keys to hash 4: def to_obj 5: self.each do |k,v| 6: if v.kind_of? Hash 7: v.to_obj 8: end 9: k=k.gsub(/\.|\s|-|\/|\'/, '_').downcase.to_sym 10: self.instance_variable_set("@#{k}", v) ## create and initialize an instance variable for this key/value pair 11: self.class.send(:define_method, k, proc{self.instance_variable_get("@#{k}")}) ## create the getter that returns the instance variable 12: self.class.send(:define_method, "#{k}=", proc{|v| self.instance_variable_set("@#{k}", v)}) ## create the setter that sets the instance variable 13: end 14: return self 15: end 16: end This works pretty well.  It converts each of your keys to properties of the Hash.  However, it doesn’t sit very well with me because I probably will not use 90% of the properties most of the time.  Why should I go through the performance overhead of creating instance variables for all of the unused ones? Enter the ‘magic method’ #missing_method: 1: class ::Hash 2: def method_missing(name) 3: return self[name] if key? name 4: self.each { |k,v| return v if k.to_s.to_sym == name } 5: super.method_missing name 6: end 7: end This is a much cleaner method for my purposes.  Quite simply, it checks to see if there is a key with the given symbol, and if not, loop through the keys and attempt to find one. I am a Ruby noob, so if there is something I am overlooking, please let me know.

  • Using Bitmap.LockBits and Marshal.Copy in IronPython not changing image as expected

    - by Leonard H Martin
    Hi all, I have written the following IronPython code: import clr clr.AddReference("System.Drawing") from System import * from System.Drawing import * from System.Drawing.Imaging import * originalImage = Bitmap("Test.bmp") def RedTint(bitmap): bmData = bitmap.LockBits(Rectangle(0, 0, bitmap.Width, bitmap.Height), ImageLockMode.ReadWrite, PixelFormat.Format24bppRgb) ptr = bmData.Scan0 bytes = bmData.Stride * bitmap.Height rgbValues = Array.CreateInstance(Byte, bytes) Runtime.InteropServices.Marshal.Copy(ptr, rgbValues, 0, bytes) for i in rgbValues[::3]: i = 255 Runtime.InteropServices.Marshal.Copy(rgbValues, 0, ptr, bytes) bitmap.UnlockBits(bmData) return bitmap newPic = RedTint(originalImage) newPic.Save("New.bmp") Which is my interpretation of this MSDN code sample: http://msdn.microsoft.com/en-us/library/5ey6h79d.aspx except that I am saving the altered bitmap instead of displaying it in a Form. The code runs, however the newly saved bitmap is an exact copy of the original image with no sign of any changes having occurred (it's supposed to create a red tint). Could anyone advise what's wrong with my code? The image I'm using is simply a 24bpp bitmap I created in Paint (it's just a big white rectangle!), using IronPython 2.6 and on Windows 7 (x64) with .Net Framework 3.5 SP1 installed.

  • DirectSho GMFBridge not working as expected

    - by user1327407
    I am trying to understand why wont the source filter connect with VMR9? mediaController.InsertSourceFilter(sinkFilter, m_pRenderGraph, out sourceFilter); var vmr = new VideoMixingRenderer9(); m_pRenderGraph.AddFilter(vmr as IBaseFilter, "VMR"); IBaseFilter vmrBase = FilterGraphTools.FindFilterByClsid(m_pRenderGraph, Clsid.VideoMixingRenderer9); IVMRFilterConfig9 xd = vmrBase as IVMRFilterConfig9; if (xd != null) { int status = xd.SetRenderingMode(VMR9Mode.Windowless); } FilterGraphTools.ConnectFilters(m_pRenderGraph, sourceFilter, vmrBase, true); mediaController.BridgeGraphs(sinkFilter, sourceFilter); Without going into too much detail: Line „ConnectFilters“ fails because no intermediate filters are found to make that connection work. When trying to debug, I can clearly see that Source filter is not spitting out anything useful. (It’s like that the sink<--source transfer never works), so that’s why it wont connect. However, when I get source filter „Output 1“ pin, and then use myGraph.Render(source_output_pin), it works. Data is being sent from sink to source and everything connects automatically. However the problem is that the wrong VMR is inserted there. It’s VMR Renderer. I would like to have VMR9, that’s why im doing it. Why wont it work with VMR9 and why does source filter not show correct media type. Thank you.

  • Switch-Case for strings in Javascript not working as expected

    - by Coltin
    So I have this problem with strings and switch-case, and I'll try to keep it as simple as possible. Here event.keyCode has the value "65", and is the result of a keydown event of 'a' (using JQuery). if (event.keyCode == "65") { alert("hmmmm"); } That works, but: switch (event.keyCode) { case '65': alert("Yay!"); break; } That doesn't. However this will work: switch ('65') { case '65': alert("Yay!"); break; } And if I do this: var t = '65'; switch (t) { case '65': alert("Yay!"); break; } It works. And then I tried this: var t = event.keyCode; switch (t) { case '65': alert("Yay!"); break; } But it fails! So why does it match in the if-block at the beginning, but not for the switch-case?

  • How to CompareTo two Object without known about their real type

    - by Kamil
    I have to implement a one linked list but it should put object in appropriate position. Everything was OK when I use it in conjunction with specific class, but when I tried make it universal and argument of method insert was Object some problem appeared. When I want to input Object in right position I should use CompareTo method, but there isn't method in Object class! The problem is how to compare two object elements without known about their real types. Maybe I should use generic class type? But what about CompareTo? Or maybe combine with Element class and place CompareTo there? I suppose it is feasible. :) public void insert(Object o) { Element el = new Element(o); // initializing and setting iterators while(!it.isDone() && ((it.current().getValue())).CompareTo(o)<0) // it.current() returns Element of List { //move interators } //... }

  • Cron Job on Ubuntu Hardy Executing But Not Deleting Files As Expected

    - by Patrick McKenzie
    I have a bit of a pickle here and wonder if anyone can give me some pointers: I have a cron job which executes for a particular user daily and is supposed to sweep files in a particular directory. Technically, it is two jobs. I've turned on cron.log to verify they're actually executing, and they are: May 24 11:03:01 AppNameGoesHere /USR/SBIN/CRON[11257]: (mongrel_AppNameGoesHere) CMD (rm -rf /var/www/apps/AppNameGoesHere/current/public/ {popular,index,purchasing,purchasing-alternate,support,about-us,guarantee,screenshots}.htm{,l}) May 24 11:04:01 AppNameGoesHere /USR/SBIN/CRON[11260]: (mongrel_AppNameGoesHere) CMD (rm -rf /var/www/apps/AppNameGoesHere/current/public/ {stats,popular,bcf,articles,expenses}) I have removed the actual usernames and formatted it so that it is less ugly on StackOverflow. Now, my question: Despite the fact that I can see these deletions executing and apparently succeeding in the log, if I go to the specified directory, the files are still there. I initially suspected permission hijinx were going on, but I've verified that I can delete the files manually by su-ing into the mongrel_AppNameGoesHere user and issuing individual rm commands or by copy/pasting the cron job to the command line. Anything that I don't manually zap stays unzapped despite days of that cron job executing successfully. Any suggestions on to what might be happening? I was previously using Dapper Drake with these cron jobs in the /etc/crontab file directly, and when I upgraded to Hardy I moved them to user-specific crontabs (via sudo crontab -e - u mongrel_AppNameGoesHere), which was the point where they appear to have stopped working.)

  • NSObject release destroys local copy of object's data

    - by Spider-Paddy
    I know this is something stupid on my part but I don't get what's happening. I create an object that fetches data & puts it into an array in a specific format, since it fetches asynchronously (has to download & parse data) I put a delegate method into the object that needs the data so that the data fetching object copies it's formatted array into an array in the calling object. The problem is that when the data fetching object is released, the copy it created in the caller is being erased, code is: In .h file @property (nonatomic, retain) NSArray *imagesDataSource; In .m file // Fetch item details ImagesParser *imagesParserObject = [[ImagesParser alloc] init:self]; [imagesParserObject getArticleImagesOfArticleId:(NSInteger)currentArticleId]; [imagesParserObject release] <-- problematic release // Called by parser when images parsing is finished -(void)imagesDataTransferComplete:(ImagesParser *)imagesParserObject { self.imagesDataSource = [ImagesParserObject.returnedArray copy]; // copy array to local variable // If there are more pics, they must be assembled in an array for possible UIImageView animation NSInteger picCount = [imagesDataSource count]; if(picCount > 1) // 1 image is assumed to be the pic already displayed { // Build image array NSMutableArray *tempPicArray = [[NSMutableArray alloc] init]; // Temp space to hold images while building for(int i = 0; i < picCount; i++) { // Get Nr from only article in detailDataSource & pic name (Small) from each item in imagesDataSource NSString *picAddress = [NSString stringWithFormat:@"http://some.url.com/shopdata/image/article/%@/%@", [[detailDataSource objectAtIndex:0] objectForKey:@"Nr"], [[imagesDataSource objectAtIndex:i] objectForKey:@"Small"]]; NSURL *picURL = [NSURL URLWithString:picAddress]; NSData *picData = [NSData dataWithContentsOfURL:picURL]; [tempPicArray addObject:[UIImage imageWithData:picData]]; } imagesArray = [tempPicArray copy]; // copy makes immutable copy of array [tempPicArray release]; currentPicIndex = 0; // Assume first pic is pic already being shown } else imagesArray = nil; // No need for a needless pic array // Remove please wait message [pleaseWaitViewControllerObject.view removeFromSuperview]; } I put in tons of NSLog lines to keep track of what was going on & self.imagesDataSource is populated with the returned array but when the parser object is released self.imagesDataSource becomes empty. I thought self.imagesDataSource = [ImagesParserObject.returnedArray copy]; is supposed to make an independant object, like as if it was alloc, init'ed, so that self.imagesDataSource is not just a pointer to the parser's array but is it's own array. So why does the release of the parser object clear the copy of the array. (I checked & double checked that it's not something overwriting self.imagesDataSource, commenting out [imagesParserObject release] consistently fixes the problem) Also, I have exactly the same problem with self.detailDataSource which is declared & populated in the exact same way as self.imagesDataSource I thought that once I call the parser I could release it because the caller no longer needs to refer to it, all further activity is carried out by the parser object through it's delegate method, what am I doing wrong?

  • winsock receiving incoming data slower than expected.

    - by k80sg
    Hi folks, I have a sender machine which sends bytearray data to my prog at an interval of about 5 miliseconds/per msg, about 6 - 7 bytearray messages per seconds that is. The problem is that the winsock in my program doesn't seem to receive these bytearray fast enough. For every 10 messages sent over, I am only able to receive about 6 to 7. Any advices? Thanks.

  • Best practise when using httplib2.Http() object

    - by tomaz
    I'm writing a pythonic web API wrapper with a class like this import httplib2 import urllib class apiWrapper: def __init__(self): self.http = httplib2.Http() def _http(self, url, method, dict): ''' Im using this wrapper arround the http object all the time inside the class ''' params = urllib.urlencode(dict) response, content = self.http.request(url,params,method) as you can see I'm using the _http() method to simplify the interaction with the httplib2.Http() object. This method is called quite often inside the class and I'm wondering what's the best way to interact with this object: create the object in the __init__ and then reuse it when the _http() method is called (as shown in the code above) or create the httplib2.Http() object inside the method for every call of the _http() method (as shown in the code sample below) import httplib2 import urllib class apiWrapper: def __init__(self): def _http(self, url, method, dict): '''Im using this wrapper arround the http object all the time inside the class''' http = httplib2.Http() params = urllib.urlencode(dict) response, content = http.request(url,params,method)

  • jQuery Validate - resetForm() Not Behaving as Expected

    - by Kevin C.
    Site in question is http://epraxadev.com/kw/palisade-palms/ "Click here for brochure" and "Learn More about Palisade Palms" both bring up a lightbox with the same HTML form to be filled out...the "learn more..." link also changes some of the HTML in the form (the value for a hidden form field, and the fields required). I'm using Colorbox for the lightbox, and for its onClosed event, I have this to reset the form: onClosed: function() { $('#brochure-form label em').remove(); $('#brochure-form').data('validator').resetForm(); } Now here's the problem: User tries to submit the "brochure" form, but it fails validation. User closes the lightbox. User opens up the "Learn more" lightbox, and tries to submit the form...now, instead of using the correct validation rules (only requiring e-mail and referrer), it requires all fields to be filled out (as is the case with the "Brochure Form") Is there something that I can add to the onClosed function, to clean up all the validation rules? Thanks guys!

  • git: 'log master..origin/master' not behaving as expected

    - by steve jaffe
    I'm trying to compare my copy of 'master' to that on the remote repository which it tracks. I thought that the following command would work, and often it seems to. However, sometimes it produces nothing and yet I know that the remote branch has many changes, which I can confirm by doing a pull. git log master..origin/master Can anyone explain this behavior and tell me what command I should be using to determine the changes between local and remote? [Another piece of data: I've had it happen that 'git log master..origin/master' produces nothing. Then I do a pull. The pull fails because I have a working copy of some file. After this, 'git log master..origin/master' does show me the differences. It seems the pull has updated some local log? If so, how could I achieve this without doing (or attempting to do) a pull?]

  • JavaScript-like Object in Python standard library?

    Quite often, I find myself wanting a simple, "dump" object in Python which behaves like a JavaScript object (ie, its members can be accessed either with .member or with ['member']).

So, is there something similar in the standard library?
