  • Which converting format of Calibre will keep a MOBI ebook's formatting together?

    - by verve
    I've got a MOBI/Kindle book and I want to convert it to a format that's easy to markup, make notes etc. but when I try to convert to TXT or PDF the result is awful. Are any of the other formats in Calibre's conversion options easily opened on any computer; any of the other formats offered by Calibre fare better after a MOBI conversion? On a side note, are there other programs that will convert a MOBI book better than Calibre? One that will keep the formatting... Win 7. IE 9.

  • How to suppress the unsolicited footer when converting HTML -> PDF with Acrobat?

    - by gojira
    I often convert & combine (via contextmenu) HTML pages to PDF using Acrobat (not Acrobat Reader). I use Adobe Acrobat Pro 9 Extended, version 9.1.2. The converted PDFs always have the full path of the original file on the bottom of the PDF-page, also they have an additional header line with the document. I need to suppress that. I do not want the unsolicited header and footer in the resulting PDF files as they are a pain to reomve manually, with a certain page count per document it becomes impossible. Is it possible to suppres that and if, how?

  • Converting ASUS Zenbook from Win8 to Win7.. do i need raid drivers?

    - by BrownChiLD
    I've got an ASUS ZEnBook Prime, ASUS Zenbook UX301LA-XH72T 13.3" Touch Ultrabook and it runs 500GB SDD on RAID 0 configuration. This notebook is running Windows 8, and i desperately need to convert to Windows 7, but maintain RAID 0 configuration. My question is, will i have problems maintaining RAID 0 once converted? I would assume that the RAID 0 configuration is BIOS based and WINDOWS wont even know it, and will only see 1 drive regardless... right? Or will i need to do some weird Windows stuff to maintain RAID 0 config? = which doesn't make sense to me why it would.

  • Mac OS X: easiest (free, non-QuickTime Pro) application for converting numbered folder of images to movie

    - by Jared Updike
    I'd like to convert a folder of PNGs into a quicktime .mov with PNG compression (it's a folder of fractals in an animation; PNG compression works great here and the losslessness is important). What programs will do this with minimal fuss? (I don't have or want to pay for a full license of QuickTime Pro.) UPDATE: Let me make this more clear: minimal fuss means: I download some EncoderMagic.app (for example), I double click it to launch it. I select the folder with my numbered images, and out pops my movie. No mess. No resizing. ... Perhaps this doesn't exist (or is called QuickTime Pro?)

  • How to train users converting from PC to Mac/Apple at a small non profit?

    - by Everette Mills
    Background: I am part of a team that provides volunteer tech support to a local non profit. We are in the position to obtain a grant to update almost all of our computers (many of them 5 to 7 year old machines running XP), provide laptops for users that need them, etc. We are considering switching our users from PC (WinXP) to Macs. The technical aspects of switching will not be an issue for the team. We are in the process of planning data conversions, machine setup, server changes, etc regardless of whether we switch to Macs or much newer PCs. About 1/4 of the staff uses or has access to a Mac at home, these users already understand the basics of using the equipment. We have another set of (generally younger) users that are technically savvy and while slightly inconvenienced and slowed for a few days should be able to switch over quickly. Finally, several members of the staff are older and have many issues using there computers today. We think in the long run switching to Macs may provide a better user experience, fewer IT headaches, and more effective use of computers. The questions we have is what resources and training (webpages, Books, online training materials or online courses) do you recommend that we provide to users to enable the switchover to happen smoothly. Especially, with a focus on providing different levels of training and support to users with different skill levels. If you have done this in your own organization, what steps were successful, what areas were less successful?

  • How to merge Windows registry hives directly without converting them to an intermediate text based file?

    - by Registrar
    Help! I'm going to get fired if I can't figure out how to do this by tomorrow. Microsoft Windows stores its registry databases (known as "registry hives" - there's actually a backstory to the origin of this name, but I digress) in a proprietary binary format. Answer this correctly or you lose your job: Let H-sub-A be the registry hive of Computer A, and let H-sub-B be the registry hive of Computer B. Create a registry hive H-sub-A-prime (in the native binary format) that contains all of the registry keys and values in both H-sub-A and H-sub-B. If there is overlap, let the value from H-sub-B overwrite the value in H-sub-A. Sure, you can import a text-based patch file (e.g., "FOO.REG") to modify the registry, but can you merge two registry hives in their native binary format? Answers that involve exporting the registry to a text file (e.g., "FOO.REG") will receive no credit. You may only use software included with Microsoft Windows (any version) and / or third-party tools that are free of charge.

  • F#: Advantages of converting top-level functions to member methods?

    - by J Cooper
    Earlier I requested some feedback on my first F# project. Before closing the question because the scope was too large, someone was kind enough to look it over and leave some feedback. One of the things they mentioned was pointing out that I had a number of regular functions that could be converted to be methods on my datatypes. Dutifully I went through changing things like let getDecisions hand = let (/=/) card1 card2 = matchValue card1 = matchValue card2 let canSplit() = let isPair() = match hand.Cards with | card1 :: card2 :: [] when card1 /=/ card2 -> true | _ -> false not (hasState Splitting hand) && isPair() let decisions = [Hit; Stand] let split = if canSplit() then [Split] else [] let doubleDown = if hasState Initial hand then [DoubleDown] else [] decisions @ split @ doubleDown to this: type Hand // ...stuff... member hand.GetDecisions = let (/=/) (c1 : Card) (c2 : Card) = c1.MatchValue = c2.MatchValue let canSplit() = let isPair() = match hand.Cards with | card1 :: card2 :: [] when card1 /=/ card2 -> true | _ -> false not (hand.HasState Splitting) && isPair() let decisions = [Hit; Stand] let split = if canSplit() then [Split] else [] let doubleDown = if hand.HasState Initial then [DoubleDown] else [] decisions @ split @ doubleDown Now, I don't doubt I'm an idiot, but other than (I'm guessing) making C# interop easier, what did that gain me? Specifically, I found a couple *dis*advantages, not counting the extra work of conversion (which I won't count, since I could have done it this way in the first place, I suppose, although that would have made using F# Interactive more of a pain). For one thing, I'm now no longer able to work with function "pipelining" easily. I had to go and change some |> chained |> calls to (some |> chained).Calls etc. Also, it seemed to make my type system dumber--whereas with my original version, my program needed no type annotations, after converting largely to member methods, I got a bunch of errors about lookups being indeterminate at that point, and I had to go and add type annotations (an example of this is in the (/=/) above). I hope I haven't come off too dubious, as I appreciate the advice I received, and writing idiomatic code is important to me. I'm just curious why the idiom is the way it is :) Thanks!

  • Is there an algorithm for converting quaternion rotations to Euler angle rotations?

    - by Will Baker
    Is there an existing algorithm for converting a quaternion representation of a rotation to an Euler angle representation? The rotation order for the Euler representation is known and can be any of the six permutations (i.e. xyz, xzy, yxz, yzx, zxy, zyx). I've seen algorithms for a fixed rotation order (usually the NASA heading, bank, roll convention) but not for arbitrary rotation order. Furthermore, because there are multiple Euler angle representations of a single orientation, this result is going to be ambiguous. This is acceptable (because the orientation is still valid, it just may not be the one the user is expecting to see), however it would be even better if there was an algorithm which took rotation limits (i.e. the number of degrees of freedom and the limits on each degree of freedom) into account and yielded the 'most sensible' Euler representation given those constraints. I have a feeling this problem (or something similar) may exist in the IK or rigid body dynamics domains. Solved: I just realised that it might not be clear that I solved this problem by following Ken Shoemake's algorithms from Graphics Gems. I did answer my own question at the time, but it occurs to me it may not be clear that I did so. See the answer, below, for more detail. Just to clarify - I know how to convert from a quaternion to the so-called 'Tait-Bryan' representation - what I was calling the 'NASA' convention. This is a rotation order (assuming the convention that the 'Z' axis is up) of zxy. I need an algorithm for all rotation orders. Possibly the solution, then, is to take the zxy order conversion and derive from it five other conversions for the other rotation orders. I guess I was hoping there was a more 'overarching' solution. In any case, I am surprised that I haven't been able to find existing solutions out there. In addition, and this perhaps should be a separate question altogether, any conversion (assuming a known rotation order, of course) is going to select one Euler representation, but there are in fact many. For example, given a rotation order of yxz, the two representations (0,0,180) and (180,180,0) are equivalent (and would yield the same quaternion). Is there a way to constrain the solution using limits on the degrees of freedom? Like you do in IK and rigid body dynamics? i.e. in the example above if there were only one degree of freedom about the Z axis then the second representation can be disregarded. I have tracked down one paper which could be an algorithm in this pdf but I must confess I find the logic and math a little hard to follow. Surely there are other solutions out there? Is arbitrary rotation order really so rare? Surely every major 3D package that allows skeletal animation together with quaternion interpolation (i.e. Maya, Max, Blender, etc) must have solved exactly this problem?

  • Converting my lightweight MySQL DB wrapper into MySQLi. Pesky Problems

  • Dynamics CRM error "A currency is required if a value exists in a money field" after converting Acti

    - by Evgeny
    We have a Dynamics CRM 4.0 instance with some custom attributes of type "money" on the Case entity and on all Activity entities (Email, Phone Call, etc.) When I use the built-in "Convert Activity to Case" functionality I find that the resulting Case does not have a Currency set, even if the Activity it was created from does have it. Whenever the case is opened the user then gets this JavaScript error: A currency is required if a value exists in a money field. Select a currency and try again. This is extremely annoying! How do I fix it? Is there any way I can set the currency? It needs to be done synchronously, because the Case is opened immediately when it's created from an Activity. So even if I started a workflow to set the currency the user would still get that error at least once. Alterntatively, can I just suppress the warning somehow? I don't really care about setting the Currency, I just want the error gone. Thanks in advance for any help!

  • Why do I get a DependencyProperty.UnsetValue when converting a value in a MultiBinding?

    - by eskerber
    I have an extremely simple IMultiValueConverter that simply OR's two values. In the example below, I want to invert the first value using an equally simple boolean inverter. <MultiBinding Converter="{StaticResource multiBoolToVis}"> <Binding Path="ConditionA" Converter="{StaticResource boolInverter}"/> <Binding Path="ConditionB"/> </MultiBinding> public class BoolInverterConverter : IValueConverter { #region IValueConverter Members public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { if (value is bool) { return !((bool)value); } return null; } public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { throw new NotImplementedException(); } #endregion } When I include the boolInverter, the first value in the MultiValueConverter becomes a "DependencyProperty.UnsetValue". There are no problems when I do not use the converter (other than not the logic I am aiming for, of course). Am I missing something? Stepping through the debugger shows that the InverseBoolConverter is properly inverting the value I pass it, but that value is then not being 'sent' to the MultiValueConverter.

  • Extra blank page when converting HTML to PDF using abcPDF.

    - by ProfK
    I have an HTML report, with each print page contained by a <div class="page">. The page class is defined as width: 180mm; height: 250mm; page-break-after: always; background-position: centre top; background-image: url(Images/MainBanner.png); background-repeat: no-repeat; padding-top: 30mm; After making a few changes to my report content, when I call abcPDF to convert the report to PDF, suddenly I'm getting a blank page inserted after every real report page. I don't want to roll back the changes I've just made to remove this problem, so I'm hoping someone may know why the extra pages are being inserted.

  • How to avoid OLEDB converting "."s into "#"s in column names?

    - by Andrew Miner
    I'm using the ACE OLEDB driver to read from an Excel 2007 spreadsheet, and I'm finding that any '.' character in column names get converted to a '#' character. For example, if I have the following in a spreadsheet: Name Amt. Due Due Date Andrew 12.50 4/1/2010 Brian 20.00 4/12/2010 Charlie 1000.00 6/30/2010 the name of the second column would be reported as "Amt# Due" when read with the following code: OleDbConnection connection = new OleDbConnection( "Provider=Microsoft.ACE.OLEDB.12.0; Data Source={0}; " + "Extended Properties=\"Excel 12.0 Xml;HDR=YES;FMT=Delimited;IMEX=1\""); OldDbCommand command = new OleDbCommand("SELECT * FROM MyTable", connection); OleDbReader dataReader = command.ExecuteReader(); System.Console.WriteLine(dataReader.GetName(1)); I've read through all the documentation I can find and I haven't found anything which even mentions that this will happen. Has anyone run into this before? Is there a way to fix this behavior?

    - by Salil
    Hi All, Sorry for this question but after spending 1-2 hours on how to read xml, i thought posting it on forum will be better. So i get a complex (very large)xml response from the plugin trackify. i want to read some values form it so i covert it into hash and then read it as follows For ex:- to read city @tracking_info['TrackResponse']['Shipment']['ShipTo']['Address']['City'] #>> "SEATTLE" my question is it proper way to getting xml response or there are some xml methods which is simple to use?

  • Converting from CVS to SVN to Hg, does 'hg convert' require pointing to an SVN checkout or just a re

  • Converting from Latitude/Longitude to Cartesian Coordinates with a World File and map image.

    - by Heath
    I have a java applet that allows users to import a jpeg and world file from the local system. The user can then "click" draw lines on the image that was imported. Each endpoint of each line contains a set of X/Y and Lat/Long values. The XY is standard java coordinate space, the applet uses an affine transform calculation with the world file to determine the lat/long for every point on the canvas. I have a requirement that allows a user to type a distance into a text field and use the arrow key to draw a line in a certain direction (Up, Down, Left, Right) from a single selected point on the screen. I know how to determine the lat/long of a point given a source lat/long, distance, and bearing. So a user types "100" in the text field and presses the Right arrow key a line should be drawn 100 feet to the right from the currently selected point. My issue is I don't know how to convert the distance( which is in feet ) into the distance in pixels. This would then tell my where to plot the point.

  • Converting from samplerate/cutoff frequency to pi-radians/sample in a discrete time sampled IIR filter system.

    - by Fake Name
    I am working on doing some digital filter work using Python and Numpy/Scipy. I'm using scipy.signal.iirdesign to generate my filter coefficents, but it requires the filter passband coefficents in a format I am not familiar with wp, ws : float Passband and stopband edge frequencies, normalized from 0 to 1 (1 corresponds to pi radians / sample). For example: Lowpass: wp = 0.2, ws = 0.3 Highpass: wp = 0.3, ws = 0.2 (from here) I'm not familiar with digital filters (I'm coming from a hardware design background). In an analog context, I would determine the desired slope and the 3db down point, and calculate component values from that. In this context, how do I take a known sample rate, a desired corner frequency, and a desired rolloff, and calculate the wp, ws values from that? (This might be more appropriate for math.stackexchange. I'm not sure)

  • Converting Asynchronous Programming Model (Begin/End methods) into event-based asynchronous model?

    - by David
    Let's say I have code that uses the Asynchronous Programming Model, i.e. it provides the following methods as a group which can be used synchronously or asynchronously: public MethodResult Operation(<method params>); public IAsyncResult BeginOperation(<method params>, AsyncCallback callback, object state); public MethodResult EndOperation(IAsyncResult ar); What I want to do is wrap this code with an additional layer that will transform it into the event-driven asynchronous model, like so: public void OperationAsync(<method params>); public event OperationCompletedEventHandler OperationCompleted; public delegate void OperationCompletedEventHandler(object sender, OperationCompletedEventArgs e); Does anyone have any guidance (or links to such guidance) on how to accomplish this?

  • Is there a programming toolkit for converting "any file type" to a TIFF image?

    - by Ryan
    Hello, I've written several variations of a program. The purpose of the program is to convert "any file type" to a TIFF image represenation of that file, as if it were being printed using a printer. I'm currently using a third party printer driver that I send files to, and it outputs a TIFF image. This is nice, but it requires me to use Office Interop files, and interact with each individual processing application in order to print the files. I had previously tried a toolkit, called Apose .NET, which did not rely on Office Interop, and did not require any printer driver. It did the conversion all on its own and would create a TIFF image. The problem with Aspose .NET was that it did not support a wide variety of input file types. Most notably, it can't do Visio files. My project calls for the ability to create a TIFF image for virtually "any file type". (excluding exes, music files, and stuff) I know that finding something that handles literally any file type is probably not a very feasible task, so I figure if it can at least handle all the Office file types, Adobe types, and other major standard file types, then I can write a custom extension parsing module that uses those processing applications to do the printing of any file type that can be viewed using those applications. So, does anyone know of a toolkit that can do this? Preferably one that does not rely on Office or a printer driver. It does not have to be free, or open source. Or, if you know of an amazing printer driver that does this, I'm open to that too. Thanks in advance, Ryan

  • How to directly rotate CVImageBuffer image in IOS 4 without converting to UIImage?

    - by Ian Charnas
    I am using OpenCV 2.2 on the iPhone to detect faces. I'm using the IOS 4's AVCaptureSession to get access to the camera stream, as seen in the code that follows. My challenge is that the video frames come in as CVBufferRef (pointers to CVImageBuffer) objects, and they come in oriented as a landscape, 480px wide by 300px high. This is fine if you are holding the phone sideways, but when the phone is held in the upright position I want to rotate these frames 90 degrees clockwise so that OpenCV can find the faces correctly. I could convert the CVBufferRef to a CGImage, then to a UIImage, and then rotate, as this person is doing: Rotate CGImage taken from video frame However that wastes a lot of CPU. I'm looking for a faster way to rotate the images coming in, ideally using the GPU to do this processing if possible. Any ideas? Ian Code Sample: -(void) startCameraCapture { // Start up the face detector faceDetector = [[FaceDetector alloc] initWithCascade:@"haarcascade_frontalface_alt2" withFileExtension:@"xml"]; // Create the AVCapture Session session = [[AVCaptureSession alloc] init]; // create a preview layer to show the output from the camera AVCaptureVideoPreviewLayer *previewLayer = [AVCaptureVideoPreviewLayer layerWithSession:session]; previewLayer.frame = previewView.frame; previewLayer.videoGravity = AVLayerVideoGravityResizeAspectFill; [previewView.layer addSublayer:previewLayer]; // Get the default camera device AVCaptureDevice* camera = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo]; // Create a AVCaptureInput with the camera device NSError *error=nil; AVCaptureInput* cameraInput = [[AVCaptureDeviceInput alloc] initWithDevice:camera error:&error]; if (cameraInput == nil) { NSLog(@"Error to create camera capture:%@",error); } // Set the output AVCaptureVideoDataOutput* videoOutput = [[AVCaptureVideoDataOutput alloc] init]; videoOutput.alwaysDiscardsLateVideoFrames = YES; // create a queue besides the main thread queue to run the capture on dispatch_queue_t captureQueue = dispatch_queue_create("catpureQueue", NULL); // setup our delegate [videoOutput setSampleBufferDelegate:self queue:captureQueue]; // release the queue. I still don't entirely understand why we're releasing it here, // but the code examples I've found indicate this is the right thing. Hmm... dispatch_release(captureQueue); // configure the pixel format videoOutput.videoSettings = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithUnsignedInt:kCVPixelFormatType_32BGRA], (id)kCVPixelBufferPixelFormatTypeKey, nil]; // and the size of the frames we want // try AVCaptureSessionPresetLow if this is too slow... [session setSessionPreset:AVCaptureSessionPresetMedium]; // If you wish to cap the frame rate to a known value, such as 10 fps, set // minFrameDuration. videoOutput.minFrameDuration = CMTimeMake(1, 10); // Add the input and output [session addInput:cameraInput]; [session addOutput:videoOutput]; // Start the session [session startRunning]; } - (void)captureOutput:(AVCaptureOutput *)captureOutput didOutputSampleBuffer:(CMSampleBufferRef)sampleBuffer fromConnection:(AVCaptureConnection *)connection { // only run if we're not already processing an image if (!faceDetector.imageNeedsProcessing) { // Get CVImage from sample buffer CVImageBufferRef cvImage = CMSampleBufferGetImageBuffer(sampleBuffer); // Send the CVImage to the FaceDetector for later processing [faceDetector setImageFromCVPixelBufferRef:cvImage]; // Trigger the image processing on the main thread [self performSelectorOnMainThread:@selector(processImage) withObject:nil waitUntilDone:NO]; } }
