  • JQuery - Fade in new Background Image?

    - by JasonS
    Hi, I think I may be trying something that isn't possible. I was recently tasked to create a html version of the flash site. On the flash site when you click on the body the image changes. I have done this with JQuery. Its brilliant! However.. it isn't "flash" enough. The powers that be want a fade effect between images. This is where I have come completely undone. This is how my script works at the moment. Images are stored in a div called photos. This is hidden. <div id="photos"> <img src="image.jpg" alt="Some caption" style="#page-bg-color" /> </div> When the page is loaded jquery checks to see if the first image is loaded. If it isn't then a loading symbol spins. When the image is loaded, it becomes the body background. $("body").css('background', 'url(' + photos[currentImage]["url"] + ') no-repeat 50% 50% fixed ' + photos[currentImage]["background"]); I have tried the following. I have tried animate. However, this doesn't work. I have tried this plugin: http://plugins.jquery.com/project/bgImageTransition This doesn't work either. It appears to clone the tag and do something. I assume it isn't working because you cannot clone the body tag. That or it is really old and is no longer compatible with the current version of JQuery. I fear that I have coded my way down a dead end. Does anybody know how I could make this work?

  • Drawing an image is completely out

    - by ct2k7
    Hi I'm using this code below to let a user "draw" their signature on a UIView component on my app: UIGraphicsBeginImageContext(signature.frame.size); [drawImage.image drawInRect:CGRectMake(0, 0, signature.frame.size.width, signature.frame.size.height)]; CGContextSetLineCap(UIGraphicsGetCurrentContext(), kCGLineCapRound); CGContextSetLineWidth(UIGraphicsGetCurrentContext(), 5.0); CGContextSetRGBStrokeColor(UIGraphicsGetCurrentContext(), 1.0, 0.0, 0.0, 1.0); CGContextMoveToPoint(UIGraphicsGetCurrentContext(), lastPoint.x, lastPoint.y); CGContextAddLineToPoint(UIGraphicsGetCurrentContext(), lastPoint.x, lastPoint.y); CGContextStrokePath(UIGraphicsGetCurrentContext()); CGContextFlush(UIGraphicsGetCurrentContext()); drawImage.image = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext() The issue I am having is that the drawing is not only is the drawing not in line with the pointer when in use in the simulator, the image is going outside of the designated UIView compontent and is getting smaller/out of focus the more I draw, as you can see in this image: And after a few lines, showing the boundaries of the exact are of where I can draw: Any ideas on what's happening here? lastPoint.y is defined as: lastPoint.y -= 20; Any ideas on what on earth is happening here?

  • wmd editor, why does it keep showing html instead of just going straight to markup

    - by Ke
    hi, im wondering how wmd is supposed to work, when i type in the textarea the text doesnt have html, but once the text is stored in db it turns to html. wmd also shows all this html when reloading the content? is it supposed to work like this? Do I have to sanitize the text before its put into the db? if so how? I thought wmd doesnt deal with html? except in code blocks. Also there are p tags being added Using the beneath html it gets added directly. I guess this could cause xss attacks? - (1) <a onmouseover="alert(1)" href="#">read this!</a> - (2) <p <script>alert(1)</script>hello - (3) </td <script>alert(1)</script>hello I wonder how is wmd supposed to work? I thought it was supposed to enter everything in its own mark up, store its on mark up and retrieve it etc. instead of storing plain html Chees Ke

  • Flex 3 - Image flickers at first load

    - 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

  • 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.

  • 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!

  • Cannot create a VSPackage for Custom Editor in Visual Studio 2010

    - by user310291
    I followed the tutorial here http://msdn.microsoft.com/en-us/vstudio/Video/bb735001 which is for VS2005. I am on VS2010. After the Wizard finished, it says A project of same name is already opened in the solution. What's the matter? I tried several times changing the name of the vspackage to be sure but always same result. Update: I tried in Visual Studio 2008 and it doesn't occur so it's really a bug in VS2010 ! Did someone try ?

  • 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.

  • 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.

  • 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".

  • 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.

  • How to Implement Rich Document Editor for iPhone

    - by benjismith
    I'm just getting started on a new iPhone/iPad development project, and I need to display a document with rich styled text (potentially with embedded images). The user will touch the document, dragging to highlight individual words or multiline text spans. When the text is highlighted, a context menu will appear, letting them change the color of highlighting or add margin notes (or other various bits of structured metadata). If you're familiar with adding comments to a Word document (or annotating a PDF), then this is the same sort of thing. But in my case, the typical user will spend many many hours within the app, adding thousands (in some cases, tens of thousands) of small annotations to the central document. All of those bits of metadata will be stored locally awaiting synchronization with a remote web service. I've read other pieces of advice, where developers suggest creating a UIWebView control and passing it an HTML string. But that seems kind of clunky, especially with all the context-sensitivity that I want to include. Anyhow, I'm brand new to iPhone development and Objective-C, though I have ten years of software development experience, using a variety of languages on many different platforms, so I'm not worried about getting my hands dirty writing new functionality from scratch. But if anyone has experience building a similar kind of component, I'm interested in hearing strategies for enabling that kind of rich document markup and annotation.
