  • mysql image disable print download

    - by Vish
    Hi, We use a Flex AIR client and a WAMP server. Tiff images are stored in MySQL. Currently, I can download the image from AIR client and it prompts for a download dialog. Things are fine till this point. We got a new requirement. Requirement is that only some users can print the image which gets downloaded. For other users, they should not be able to print the tiff image. Wondering how to accomplish this. One idea, not sure if its efficient, is to convert the image requested to pdf at the server side, disable print option there(hope there are API's available) and send back the pdf. Please let me know btter ideas. Also, is there a way to prevent file download dialog from popping up everytime the file is requested for download? Can we just get the file stream to the client and manipulate it to open with a particular viewer or write it to pdf... Please help.

  • RetinaJS and LESS : Background image doesn't show on iOS

    - by jidma
    I am trying to make a background image into a retina image using LESS CSS and RetinaJs: in my index.html file : <html> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=0, minimum-scale=1.0, maximum-scale=1.0"> <meta name="apple-mobile-web-app-capable" content="yes"> <meta name="apple-mobile-web-app-status-bar-style" content="black"> [...] <link type="text/css" rel="stylesheet/less" href="resources/css/retina.less"> <script type="text/javascript" src="resources/js/less-1.3.0.minjs" ></script> [...] </head> <body> [...] <script type="text/javascript" src="resources/js/retina.js"></script> </body> </html> in my retina.less file: .at2x(@path, @w: auto, @h: auto) { background-image: url("@{path}"); @at2x_path: ~`"@{path}".split('.').slice(0, "@{path}".split('.').length - 1).join(".") + "@2x" + "." + "@{path}".split('.')["@{path}".split('.').length - 1]`; @media all and (-webkit-min-device-pixel-ratio : 1.5) { background-image: url("@{at2x_path}"); background-size: @w @h; } } .topMenu { .at2x('../../resources/img/topMenuTitle.png'); } I have both topMenuTitle.png (320px x 40px) and [email protected] (640px x 80px) in the same folder. When test this code: In Firefox i have the normal Background In the XCode iPhone simulator I also have the normal Background In the iPhone device, I don't have any background at all.

  • How do i programmatically access the face cache in Windows Live Photo Gallery?

    - by acorderob
    I'm not talking about the "people tags" embeded in the XMP packets of JPEGs. I'm talking about the face database used to recognize new faces. I want to add to my program the option to recognize faces using the already trained database of WLPG. I managed to use the API (a type library dll) to detect faces, but to recognize them it needs an Exemplar Cache object that is not available in the same API. I could create my own object, but i want to use the already existing one to avoid duplicate training for the user. I know the database is in C:\Users\\AppData\Local\Microsoft\Windows Live Photo Gallery and that it is in an SQL Server Compact format. I tried to open the database with Visual Studio 2010, but it says that it is in an older version (pre-3.5) and needs to be upgraded. I don't want to change the database, just read it. I don't know how the WPLG reads it since apparently i don't have the correct OLEDB provider version. I would also prefer to read it without accesing the database directly but i don't see any DLL that exports that functionality. BTW, i'm using Delphi 2010. Any ideas?

  • jQuery ajax post of jpg image to .net webservice. Image results corrupted

    - by sosergio
    I have a phonegap jquery app that opens the camera and take a picture. I then POST this picture to a .net webservice, wich I've coded. I can't use phonegap FileTransfer because such isn't supported by Bada os, wich is a requirement. I believe I've successfully loaded the image from phonegap FileSystem API, I've attached it into an .ajax type:post, I've even received it from .net side, but when .net save the image into the server, the image results corrupted. It seems to me that two sides of the communication have different data type. Has anyone experience in this? Any help will be appreciated. This is my code: //PHONEGAP CAMERA ACCESS (summed up) navigator.camera.getPicture(onGetPictureSuccess, onGetPictureFail, { quality: 50, destinationType:Camera.DestinationType.FILE_URI }); window.resolveLocalFileSystemURI(imageURI, onResolveFileSystemURISuccess, onResolveFileSystemURIError); fileEntry.file(gotFileSuccess, gotFileError); new FileReader().readAsDataURL(file); //UPLOAD FILE function onDataReadSuccess(evt) { var image_data = evt.target.result; var filename = unique_id(); var filext = "jpg"; $.ajax({ type : 'POST', url : SERVICE_BASE_URL+"/fotos/"+filename+"?ext="+filext, cache: false, timeout: 100000, processData: false, data: image_data, contentType: 'image/jpeg', success : function(data) { console.log("Data Uploaded with success. Message: "+ data); $.mobile.hidePageLoadingMsg(); $.mobile.changePage("ok.html"); } }); } On my .net Web Service this is the method that gets invoked: public string FotoSave(string filename, string extension, Stream fileContent) { string filePath = HttpContext.Current.Server.MapPath("~/foto_data/") + "\\" + filename; FileStream writeStream = new FileStream(filePath, FileMode.OpenOrCreate, FileAccess.Write); int Length = 256; Byte[] buffer = new Byte[Length]; int bytesRead = readStream.Read(buffer, 0, Length); // write the required bytes while (bytesRead > 0) { writeStream.Write(buffer, 0, bytesRead); bytesRead = readStream.Read(buffer, 0, Length); } readStream.Close(); writeStream.Close(); }

  • Combining two .png images into one image using .NET

    - by Omega
    I have two (actually many) .png images in my application. Both have transparent areas here and there. I want, in my application, to take both images, combine them, and display the result in a picture box. Later I want to save the result through a button. So far I managed to find the two images and combine them, but it seems the transparency thing won't work. I mean, if you put one image over another, only the top image is visible as the result because, apparently, the image's background is a plain white box. Which is not. Here is a bit of my code: Dim Result As New Bitmap(96, 128) Dim g As Graphics = Graphics.FromImage(Result) Dim Name As String For Each Name In BasesCheckList.CheckedItems Dim Layer As New Bitmap(resourcesPath & "Bases\" & Name) For x = 0 To Layer.Width - 1 For y = 0 To Layer.Height - 1 Result.SetPixel(x, y, Layer.GetPixel(x, y)) Next Next Layer = Nothing Next resourcesPath is the path to my resources folder. Bases is a folder in it. And Name is the image's name. Thank you.

  • Convert Justified Paragraph To Image

    - by rsrobbins
    I need to convert a paragraph of text into an image. Converting the text into an image is no problem. I have the code to do that. But the text must be shown as a paragraph with each line centered. That is a problem! Currently I can convert the text into a left justified paragraph because there are carriage returns in the text string. I suppose it could be center justified with spaces in the string but it would be hard to calculate the required spaces. There must be an easier way. What I need is some way to format the text into a paragraph and then convert it back into a string, preserving spaces. This needs to be done in VB.NET for an ASP.NET web application. Any ideas? I could get the paragraph justified in Rich Text Format but I don't know if it can be converted back into a string, preserving spaces. Creating a PDF is another possibility. The image created from the text needs to be 300 DPI with a transparent background. I'm using the DrawString method of a Graphics object to create the image.

  • Disambiguating Named Entities in Java

    - by Alterscape
    I have a list of strings (company names, in this case), and a Java program that extracts a list of things that look like company names out of mostly-unstructured text. I need to match each element of extracted text to a string in the list. Caveat: the unstructured text has typos, things like "Blah, Inc." referred to as "Blah," etc. I've tried Levenshtein Edit Distance, but that fails for predictable reasons. Are there known best-practices ways of tackling this problem? Or am I back to manual data-entry?

  • form submit button moves cutting image

    - by flavour404
    Hi I have a submit button and am styling it using the following css: .subm { background-color:Transparent; background-image:url(Images/Button_Send.png); background-repeat:no-repeat; width:82px; height:30px; display:block; border:none; outline:none; overflow:visible;} .subm:hover { background-color:Transparent; background-image:url(Images/Button_Send_Over.png); background-repeat:no-repeat; width:82px; height:30px; display:block; border:none; outline:none; overflow:visible; } Here is the html: <input type="submit" class="subm" value="" /> Nothing surprising. However, what annoys me is that when the submit button is clicked in IE it moves the image up a couple of pixels cutting them off which makes it look, hmm, good word, 'naff.' How can I compensate or stop this? I have tried expanding the image and leaving a couple of blank pixels at the top but it still does the same thing! Thanks R.

  • Flex 3 - Remove image flickering

    - by BS_C3
    Hello Community! I have an application with different components that are accessible through a viewstack in the main application. The main application looks like that: <Application> <Viewstack> <myComponent1/> <myComponent2/> <myComponent3/> . . . </Viewstack> </Application> In myComponent1, I have a horizontalList where the user can select a product. In myComponent2, I have 2 containers inside the component. A left container with a larger image of the product selected in myComponent1 and a right container with all characteristics of the product. Both containers have an embed background image. When I select a product in myComponent1, the application displays myComponent2. When the component is displayed, I first see the page without the large image of the product, then both containers flickers and the product image is displayed. How could I avoid this flickering? It's really annoying _< Thanks in advance for your help =) Regards. BS_C3

  • Actionscript: How Can I Know When The Source Property Of An Image Is Completely Updated

    - by Joshua
    var I:Image=new Image(); I.source='C:\\Abc.png'; var H:int=I.height; H is always Zero! I am presuming this is because the image hasn't finished reading the png file off the disk yet. What event can I monitor to know when it's width and height will have the right values? The 'Complete' event only seems to work for DOWNLOADED images. The 'Render' event happens EVERY FRAME. The (undocumented?) 'sourceChanged', happens as soon as source changes, and has the same problem! What event do I watch that will let me know when the image's width and height properties will have valid values? Or is there some Synchronous version of I.source='xxx.png', that I don't know about? P.S. Yes, I know I shouldn't use "C:\" in an Air Program. This was just for illustrative purposes, so that you won't suggest I use "Complete", which never even seems to fire when the file indicated by source is local.

  • Is it possible to run JavaScript and also edit image maps using Design View in Dreamweaver?

    - by Mike Eng
    I'm using Dreamweaver CS5.5 for an HTML prototype that is built with image-mapped screenshots. I am using JavaScript to dynamically include the appropriate main image, and the navigation is done with image maps. Is it possible to have the Dreamweaver "Design View" run JavaScript initially (which will set the main image) and also allow me to edit the image maps in place (so I can see them placed over the correct main image)? I found some references to the "Live View" feature, which runs JavaScript successfully, but I cannot see or edit image maps in "Live View".

  • Windows Mobile 6.5 flick (scrolling with inertia) not working

    - by GRR
    After upgrading to windows mobile 6.5, my ListView control does not work properly with custom items (rows with alternate colors) and the new gesture mechanism... On a mobile device, if the user initiates a flick or pan, after scrolling the first few items, the last items are not shown on the screen, but will show up if the user explicitly taps on them -- so basically the last screen is just white. The WM_DRAWITEM message is sent to all children though, but they just don't show up on the screen. Scrolling with a bar works fine. Any ideas? I have seen some reports of similar behavior from other users, but not sure if this is a bug in the listview control itself or if there is something else that needs to/can be implemented to support flick and pan actions. The application code currently doesn't handle WM_GESTURE messages, so the flick action is done with Microsoft's own code to support legacy applications. Thanks!

  • "Voice trigger" detection

    - by sehugg
    I have a voice application that would be much-improved if there was the ability to use a "trigger word" to start recording audio. I don't need a full speech-text engine, just the ability to reliably/efficiently detect the trigger word. I am wondering if there are any specialized speech engines that support this specific use case, or any libraries/methods to developing such a single-purpose detection engine. Ideally I'd like it to work in noisy environments, but it can be trained for a single user's voice. Pointers to research papers / topics would also be appreciated so I know what to ask for.

  • Iphone: XML image problem

    - by avanadra
    Hi! I have a question about parsing XML and putting it into a table. I parsed the following elements from a RSS feed : title, dc:creator and enclosure url (= an image). The parsing is working, i can see everything showing up in the console. But when i try to load everything into the tablecell, everything shows up except for the image. So i figured that the problem must be in the CellForRowatIndexPath method in the RootViewController.m ( or in the TableCell.m) What am i doing wrong? Please help! Ive been struggling for days with this and just cant seem to figure it out! Heres the CellForRowatIndexPath: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; WerkTableCell *cell = (WerkTableCell *) [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { [[NSBundle mainBundle] loadNibNamed:@"WerkCell" owner:self options:nil]; cell =self.werkCell; } // Configure the cell. NSMutableArray *cont= [xmlcont items];// is niet in tablevb v. PS ItemData *current =[cont objectAtIndex:indexPath.row]; cell.titelLabel.text = [current titel]; cell.makerLabel.text = [current maker]; cell.thumbImage.image = [UIImage imageNamed:[current image]]; return cell; }

  • Asp.net MVC - Model binding image button

    - by big dave
    I've got a very complex form and i'm using the MVC model binding to capture all the information I've got it set up to capture all the different submissions that can happen as there are about 10 different submit buttons on the form, and there are also 2 image buttons I tried to get a bit clever (or so i thought) with capturing the image button submissions, and have created a child class so that i can capture the x value that's returned public class ImageButtonViewData { public int x { get; set; } public string Value { get; set; } } The parent class looks something like this public class ViewDataObject { public ImageButtonViewData ImageButton { get; set; } public ViewDataObject(){ this.ImageButton = new ImageButton(); } } The html for the image button then looks like <input type="image" id="ViewDataObject_ImageButton" name="ViewDataObject.ImageButton" /> This works fine in all browsers except for Chrome. When i debug it in chrome, the Request.Form object contains the values that i would expect, but after the model binding has occurred, the ImageButton property on the ViewDataObject has been set to null The only difference that i can see between the submission values is that Chrome passes the x as lower case (ViewDataObject.ImageButton.x) and IE passes it as upper case (ViewDataObject.ImageButton.X) but i didn't think that model binding took any notice of casing on property names Does anyone have any ideas ?
