  • HTML javascript form submitted when image input button

    - by DreamU
    I have a form that contains this single input field, which is nothing more than a button to Print the current web page: <div align="center"> <input type="image" src="../Images/print.jpg" value="Print" onclick="printpage();" /></div> </div> After the printing, the page re-submits itself (to itself). Why does it do this and can I stop it? If I just change the type to "input", this code does not re-submit itself after printing: <div align="center"> <input type="input" src="../Images/print.jpg" value="Print" onclick="printpage();" /></div> </div> Unfortunately, our style conventions require me to use that button image rather than the standard input button.

  • How do I create an image for a UITableViewCell dynamically

    - by Xetius
    I want to dynamically create an image for a UITableViewCell which is basically a square with a number in it. The square has to be a colour (specified dynamically) and contains a number as text inside it. I have looked at the CGContextRef documentation, but can't seem to work out how to get the image to fill with a specified certain colour. This is what I have been trying so far. -(UIImage*)createCellImageWithCount:(NSInteger)cellCount AndColour:(UIColor*)cellColour { CGFloat height = IMAGE_HEIGHT; CGFloat width = IMAGE_WIDTH; UIImage* inputImage; UIGraphicsBeginImageContext(CGSizeMake(width, height)); CGContextRef context = UIGraphicsGetCurrentContext(); UIGraphicsPushContext(context); // drawing code goes here // But I have no idea what. UIGraphicsPopContext(); UIImage* outputImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); return outImage; }

  • Showing an image after loading it from sql database

    - by user330075
    I have a problem showing the image form database in a view Details and a ImageController. Inside the view I have: img src=Url.Action("GetFile","Image", new {id= Model.id}) and in controller: public FileContentResult GetFile(int idl) { //int idl = 32; SqlDataReader rdr; byte[] fileContent = null; ........... return File(,,); } When the view is called, function GetFile it just won't work. But if I cut out the parameter int id1 and I instantiate it as a variable it does work. public FileContentResult GetFile() { int idl = 32; SqlDataReader rdr; byte[] fileContent = null; ........... return File(,,); } Why?

  • Preloading CSS Background Images

    - by Peanuts
    Hello guys, I have a hidden contact form which is deployed clicking on a button. Its fields are set as CSS background images, and they always appears a bit later than the div that have been toggled. I was using this snippet in the <head> section, but with no luck (after I cleared the cache) : <script type="text/javascript"> $(document).ready(function() { pic = new Image(); pic2 = new Image(); pic3 = new Image(); pic.src="<?php bloginfo('template_directory'); ?>/images/inputs/input1.png"; pic2.src="<?php bloginfo('template_directory'); ?>/images/inputs/input2.png"; pic3.src="<?php bloginfo('template_directory'); ?>/images/inputs/input3.png"; }); </script> I'm using jQuery as my library, and it would be cool if I could use it as well for arranging this issue. Thanks for your thoughs.

  • Creating Thumbnails with CFImage Aborting Because of Server Load?

    - by nephilite
    I am uploading in image via a form and I want to, in addition to saving the image, save a variety of thumbnails in both png and jpg format. To do this I am using the code below. The initial image uploads fine but then, after spinning for a moment I get an error of: "Request aborted due to heavy system load." (from my host crystaltech), and none of the thumbnails have made it through. I've tried it with even just one resize (and no converts) and it still fails. What am I doing wrong? This issue is somewhat urgent....Thanks! ` <cffile action="upload" destination="#Application.filePath#Icons\#app#Icon.png" filefield="Icon" nameconflict="overwrite"> <cfimage source="#Application.filePath#Icons\#app#Icon.png" action="resize" width="50%" height="50%" destination="#Application.filePath#Icons\#app#Icon_Half.png" overwrite="yes"> <cfimage source="#Application.filePath#Icons\#app#Icon.png" action="resize" width="25%" height="25%" destination="#Application.filePath#Icons\#app#Icon_Quarter.png" overwrite="yes"> <cfimage source="#Application.filePath#Icons\#app#Icon.png" action="convert" destination="#Application.filePath#Icons\#app#Icon.jpg"> <cfimage source="#Application.filePath#Icons\#app#Icon_Half.png" action="convert" destination="#Application.filePath#Icons\#app#Icon_Half.jpg"> <cfimage source="#Application.filePath#Icons\#app#Icon_Quarter.png" action="convert" destination="#Application.filePath#Icons\#app#Icon_Quarter.jpg"> `

  • Rails - Paperclip, getting width and height of image in model

    - by Corey Tenold
    Trying to get the width and height of the uploaded image while still in the model on the initial save. Any way to do this? Here's the snippet of code I've been testing with from my model. Of course it fails on "instance.photo_width". has_attached_file :photo, :styles => { :original => "634x471>", :thumb => Proc.new { |instance| ratio = instance.photo_width/instance.photo_height min_width = 142 min_height = 119 if ratio > 1 final_height = min_height final_width = final_height * ratio else final_width = min_width final_height = final_width * ratio end "#{final_width}x#{final_height}" } }, :storage => :s3, :s3_credentials => "#{RAILS_ROOT}/config/s3.yml", :path => ":attachment/:id/:style.:extension", :bucket => 'foo_bucket' So I'm basically trying to do this to get a custom thumbnail width and height based on the initial image dimensions. Any ideas?

  • How to create a gesture controlled rotating image for a UI

    - by ocdtrekkie
    I'm trying to figure out the best way to make an image rotate along with a user's finger dragging it left or right. I want to try and match the rate a user's finger is moving with the rate the image is rotating. I've got the basic setup for my application going, with the menus and whatnot I want to have, and that's all running great on the emulator, I'm just not sure how to approach this part. I can code all the logic I need for my app, I'm just not doing to well designing the UI, I have a picture in mind, I've actually made a couple mock images of it, I just can't figure out how to get it going in Android, and any help would be appreciated.

  • staying within boundaries of image?

    - by codefail
    So I am to loop through copyFrom.pixelData and copy it into pixelData. I realize that I need to check the conditions of i and j, and have them not copy past the boundaries of pixelData[x][y], I need another 2 loops for that? I tried this, but was getting segmentation fault.. Is this the right approach? void Image::insert(int xoff, int yoff, const Image& copyFrom, Color notCopy) { for (int x = xoff; x < xoff+copyFrom.width; x++) { for (int y = yoff; y < yoff+copyFrom.height; y++) { for (int i = 0; i<width; i++){ for (int j = 0; j<height; j++){ if (copyFrom.pixelData[i][j].colorDistance(notCopy)>20 ) pixelData[x][y]=copyFrom.pixelData[i][j]; } } } } }

  • jquery - sliding image group left and right (hiding the ones that are past a certain point)

    - by matthewsteiner
    So I'm not really sure how to go about doing this at all. I've got an anchor on the left with id="left" and one on the right with id="right". On the hover event, the image thumbnails should start sliding left or right. If there's not enough thumbnails, there should be no sliding. It can only fit 4 images in between the left and right anchors. How can I hide all anchors that are not in between the left and right anchors? I want the images to actually slowly move left or right, not just be sudden. Any ideas? I know how to bind the events and such just fine. I just don't really now how to get started with the image placement.

  • No image displayed in Fancybox

    - by seansean11
    I am having trouble getting fancybox to display its corresponding images on a website that I'm building http://www.nomadicdrift.com/test/kaniwa#events . It's a custom one page portfolio theme that I set up on the WordPress platform. If you follow the link to the events section you will see 1 figure item in a gallery like position. I have this image set up to work as a fancybox gallery, but when you click on it, it opens up the fancybox interface but does not place a image in the frame, even though it should. So this is the problem...the images do not show up in fancybox and instead I see just the frame. Here is the html that I'm displaying: <figure> <a class="fancybox" data-fancybox-type="Fashion Show de Paris, France" href="http://www.nomadicdrift.com/test/kaniwa/wp-content/uploads/2012/07/NM2.jpg"> <img class="attachment-evento wp-post-image" width="231" height="191" title="NM" alt="NM" src="http://www.nomadicdrift.com/test/kaniwa/wp-content/uploads/2012/07/NM2-231x191.jpg"> </a> <figcaption> <a class="fancybox" data-fancybox-type="Fashion Show de Paris, France" href="http://www.nomadicdrift.com/test/kaniwa/wp-content/uploads/2012/07/CEDESAN.jpg"> </a> <h4>Fashion Show de Paris, France</h4> </figcaption> </figure> I'm not going to bore you with the PHP that I used to get that output because I think the problem lies elsewhere. ***I have tried to set up a simple standard fancybox gallery on the site also, but it gives me thes same problem, leading me to believe that the problem is deeper than the html markup. I have also successfully used this same markup for a one thumbnail fancybox gallery on another site. I thought maybe it was due to some conflict in the .js files I'm using. I tried uninstalling all of my plugins/addons (which aren't too many) one by one and still had the same result. I have all of my personal javascript in the functions.js file, which is where I call the fancybox plugin using the standard $("a.fancybox").fancybox();. I have installed this plugin before on other sites and have searched extensively for an answer, so any help is greatly appreciated. Thanks, Sean
