  • Partial Upload With storbinary in python

    - by brian
    I've written some python code to download an image using urllib.urlopen().read() and then upload it to an FTP site using ftplib.FTP().storbinary() but I'm having a problem. Sometimes the image file is only partially uploaded, so I get images with the bottom 20% or so cut off. I've checked the locally downloaded version and I have successfully downloaded the entire image, which leads me to believe that it is a problem with storbinary. I believe I am opening and closing all of the files correctly. Does anyone have any clues as to why I'm getting a partial upload with storbinary? Update: When I run through the commands in the Python shell, the upload completes successfully, I don't know why it would be different from when run as a script...

  • What is the best way in Silerlight to make areas of a large graphic clickable?

    - by Edward Tanguay
    In a Silverlight application I have large images which have flow charts on them. I need to handle the clicks on specific hotspots of the image where the flow chart boxes are. Since the flow charts will always be different, the information of where the hotspots has to be dynamic, e.g. in a list of coordinates. I've found article like this one but don't need the detail of e.g. the outline of countries but just simple rectangle and circle areas. I've also found articles where they talk about overlaying an HTML image map over the silverlight application, but it has to be easier than this. What is the best way to handle clicks on specific areas of an image in silverlight?

  • Opening response stream in silverlight

    - by John Maloney
    Hello, I am attempting to return a image from a server using Silverlight 3. The server returns the Response stream like this: context.Response.ContentType = imageFactory.ContentType imgStream.WriteTo(context.Response.OutputStream) imgStream.Close() context.Response.End() On the Silverlight client I am handling the stream like: Dim request As HttpWebRequest = result.AsyncState Dim response As HttpWebResponse = request.EndGetResponse(result) Dim responseStream As IO.Stream = response.GetResponseStream() I want to take that stream and open the browsers save dialog, one option I have explored is using the Html.Window.Navigate(New Uri("image url")) and this opened the correct browser default dialog but it is not an option because I need to send extended information(e.g. XML) to the server through the HttpRequest.Headers.Item and the Navigate doesn't allow this. How can I take a Response Stream and force the default browser Save dialog to appear from the Silverlight Application without using the Html.Window.Navigate(New Uri("image url"))?

  • Technical reasons for not having large background images in websites

    - by kees-kist
    Most websites tend to have either a solid color as background, or a small image that is repeated. Why aren't more websites using a large image (such as a photo) as background? I can think of the following reasons: 1) Problems with different screen resolutions. Too small and gaps start to appear on the left and/or right side for higher resolutions, too big and lower resolutions only show part of the image. 2) Bandwidth. Although this is unlikely to be a problem for most websites. Are there any other reasons why such backgrounds are not being used more often?

  • iPhone: One Object, One Thread

    - by GingerBreadMane
    On the iPhone, I would like to do some operations on an image in a separate thread. Rather than dealing with semiphores, locking, etc., I'd like to use the 'One Object, One Thread' method of safely writing this concurrent operation. I'm not sure what is the correct way to copy my object into a new thread so that the object is not accessed in the main thread. Do I use the 'copy' method? If so, do I do this before the thread or inside the thread? ... -(void)someMethod{ UIImage *myImage; [NSThread detachNewThreadSelector:@selector(getRotatedImage:) toTarget:self withObject:myImage]; } -(void)getRotatedImage:(UIImage *)image{ ... ... UIImage *copiedImage = [image copy]; ... ... }

  • iPhone stretchableImageWithLeftCapWidth only makes "D"s.

    - by Jill
    UIImage *aImage = [[UIImage imageNamed:@"Gray_Button.png"] stretchableImageWithLeftCapWidth:25 topCapHeight:0]; Trying to make a "glass pill button". What does "stretch" do if the image is bigger... and the button I'm trying to use it on... is smaller? Does the image 'stretch' and 'shrink'? The reason I ask... is because all my images end up look like a "D" shape. The left side is squared-off... and the right side is rounded. What would a D-shape tell you that I'm doing wrong? Too much.. or too little... "leftCap setting"? Too large an image?

  • Font-awesome, input type 'submit'

    - by denis.peplin
    It seems no class for input type 'submit' in font-awesome. Is it possible to use some class from font-awesome for button input? I've added icons to all buttons (which actually links with class 'btn' from twitter-bootstrap) in my applications, but can't add icons on 'input type submit'. Or, how to use this code: input#image-button{ background: #ccc url('icon.png') no-repeat top left; padding-left: 16px; height: 16px; } html: <input type="submit" id="image-button">Text</input> (which I took from HTML: How to make a submit button with text + image in it?) with font-awesome?

  • PHP getimagesize is not working when is called from a function in function.php (Wordpress)?

    PHP getimagesize is not working when is called from a function in function.php. function.php: add_action('wp_head', 'get_image_size'); function get_image_size() { global $width; // I thought this would solve the problem but it didn't global $height; // I thought this would solve the problem but it didn't list($width, $height, $type, $attr) = getimagesize($options['logo']); echo "Image width " .$width; echo "<BR>"; echo "Image height " .$height; echo "<BR>"; } $options['logo'] is returning http://localhost/wordpress/wp-content/uploads/2010/12/logo4.png so the image is being displayed. I also did var_dump to $width and $height but they didn't show up. Any suggestions?

  • change Magento to new server, images of existing product do not shown in frontend

    - by forrest gump
    I have moved a Magento website to a new server to optimize speed. All images appear to be replaced by image placeholders. I tried to set permission for media to 777, when I delete cache media folder and refresh, a new cache folder is created automatically, but only with placeholder images inside. I flushed image cache, reindex in magento backend but still no hope. What should I do now? Somethings might be helpful: . It's fine to create new product with images . Flush cache, only placeholders images are created . tried to use magento-cleanup.php, no hope . tried to remove .htaccess in media folder . the images of products are there in the media folder, just not in cache folder. Magento only looks at the cache folder for image :(

  • Convert jpg Byte[] to Texture2D

    - by Damien Sawyer
    I need to import jpeg images into a WP7/XNA app with associated metadata. The program which manages these images exports to an XML file with an encoded byte[] of the jpg files. I've written a custom importer/processor which successfully imports the reserialized objects into my XNA project. My question is, given the byte[] of the jpg, what is the best way to convert it back to Texture2D. // 'Standard' method for importing image Texture2D texture1 = Content.Load<Texture2D>("artwork"); // Uses the standard Content processor "Texture - XNA Framework" to import an image. // 'Custom' method var myCustomObject = Content.Load<CompiledBNBImage>("gamedata"); // Uses my custom content Processor to return POCO "CompiledBNBImage" byte[] myJPEGByteArray = myCustomObject.Image; // byte[] of jpeg Texture2D texture2 = ???? // What is the best way to convert myJPEGByteArray to a Texture2D? Thanks very much for your help. :-) DS

  • Control process concurrency in PHP

    - by Ivan
    I have programmed a simple app that every X minutes checks if an image has changed in several websites and downloads it. It's very simple: downloads image header, make some CRC checks, downloads the file, stores in a MySQL database some data about each image and process next item... This process takes about 1 minute to complete. The problem is I have noticed that while the server is executing this process I cannot access to any page in the website, even those that don't require MySQL. I don't know why it is happening and I have no clue about how to fix it. Perhaps a more advanced PHP programmer can help me.

  • How to load images and fragments dynamically in LiveCycle Designer forms?

    - by John
    Hi there. I've created a couple of shared templates (.xdp) which will be shared among several clients. Obviously, each client has their own logo and I'd like to set the logo upon form generation. I've managed to change the logo dynamically although I'm not sure if my approach is good. In the xml datasource I've got this element: <ClientID>SomeNumber</ClientId> In the form itself I set the image href with this javascript code: SomeHiddenTextField::calculate HeaderLogo.value.image.href = $record.ClientID + "_logo.jpg"; I've got the logos stored on the server in the same folder as the shared templates. Is this an alright approach to load logos dynamically? I've been trying to achieve the same dynamic behaviour with each client's footer fragment, but I have been unable to figure out how to load these on demand. I could make each footer fragment in to an image but I'd like to avoid it if possible.

  • IE6 extra padding on bottom

    - by Gian Basagre
    I have a div tag styled through CSS. I set the padding to 10px (padding:10px), it works just as I wanted in Firefox and IE7, but in IE6 it adds additional padding at the bottom (about 2-3px I think). Anyone has idea about what's happening here? [update] I just noticed this, the div tag I'm talking about has a background-image. When I removed the background-image, the extra padding on the bottom disappears. Any ideas? [another update, code sample] Here's the CSS applied to my div tag: .user-info{ margin-top: 20px; margin-right: 20px; padding: 10px; background-image: url("../img/user_panel_bg.png"); float:right; border: 1px #AAAAAA solid; font-size:12px; }

  • Replacing substring in a string

    - by user177785
    I am uploading a image file to the server. Now after uploading the file to the server I need to rename the file with an id, but the extension of the file should be retained. Eg: if I upload the file image1.png then my server script should retain the extension .png. But I need to change the substring to some other substring (primary key of db). image1.png should be renamed to 123.png image2.jpg should be renamed to somevalue.jpg The image can be of any extension like .png, .jpg, .jpeg etc. I want to rename then in such a way that the image/file extension should be retained.

  • How I can use the HTTP headers to indicate in the Response that possibility?

    - by Cris Hong Kong CRISHK
    Finally I accomplished to cache dynamic images, css, and javascript files using HTTP headers BUT I have a problem now: I have specific dynamic images that are equal but has different URL's. For example: http://example.com/image/src/the-same-image.jpg http://example.com/image/custom/src/the-same-image2.jpg 1 and 2 has the same file content but different URL. This is a problem now because the navigator assumes that the file are different and need to be cached (due to the URL), when the real cached file is only one. I have the possibility to know if the file at the URL's are the same. How I can use the headers to indicate in the Response that possibility, and the navigator will cache only one file?

  • How to design websites for all display sizes

    - by katie bekell
    I like to use a lot of unique graphics on my pages, which often results in making different page sizes depending on available screen width/height. Here are two examples: http://www.uvm.edu/~areid/homesite/ - the image floats at the bottom of my screen but on a larger browser, the image floats near the middle making it look off. It looks best when the bottom of the window aligns with the bottom of the image www.stevenlebel.com - it loads two different pages depending on what monitor size is detected. This seems like a lot of redundant coding. My question is, how can I make sliced/Photoshop images transition well to different screen sizes. Does Photoshop allow you to make DIVS instead of tables? Can i make each of the slices created by Photoshop grow/shrink when the browser window size changes? If anyone has any input on creating websites like this I would be very interested to hear what they have to say. Thanks Katie

  • Text wrap in a <canvas> element

    - by Gwood
    I am trying to add text on an image using the <canvas> element. First the image is drawn and on the image the text is drawn. So far so good. But where I am facing a problem is that if the text is too long, it gets cut off in the start and end by the canvas. I don't plan to resize the canvas, but I was wondering how to wrap the long text into multiple lines so that all of it gets displayed. Can anyone point me at the right direction?

  • Can you create a HIPAA compliant Amazon S3 Web Application?

    - by xkingpin
    I am facing some questions when trying to design an S3 application using ASP.NET MVC and trying to stay HIPAA compliant. My initial plan was to require an SSL connection to my web server, encrypt the images on my server, then send them to s3 using my private keys. Here's my obvious concerns: You cannot store unencrypted images in any temporary file cache when client views images within the browser. Even if I setup an ashx to generically handle the image in memory, couldn't this get stored in cache? Saying the images will be encrpyted because you will be connecting to my server via https still does not guarantee all browsers will not cache data. It's not possible to even consider the "Query String" with expiration option since data will be encrypted before being stored on disk at s3, and will again be decrypted at my server in memory. I think my only option would be to write/purchase some sort of ActiveX component that will not expose the image as a simple html image source or write my app as a client side WinForm application.

  • Mono Ignores Graphics.InterpolationMode?

    - by Timothy Baldridge
    I have a program that draws some vector graphics using System.Drawing and the Graphics class. The anti-aliasing works, kindof okay, but for my need I neede oversampling, so I create the starting image to be n times larger and then scale back the final image by n. On Window and .NET the resulting image looks great! However, on Mono 2.4.2.3 (Ubuntu 9.10 stock install), the intropolation is horrible. Here's how I'm scaling my images: Bitmap bmp = new Bitmap(Bmp.Width / OverSampling, Bmp.Height / OverSampling); Graphics g = Graphics.FromImage(bmp); g.InterpolationMode = InterpolationMode.HighQualityBicubic; g.DrawImage(Bmp, 0, 0, bmp.Width, bmp.Height); g.Dispose(); From what I can tell there is no interpolation happening at all. Any ideas?

  • Horizontal and vertical center text inside div

    I have a div with a background image that needs to be centered horizontally and vertically. On top of that image, I also want to display some text, also centered horizontally and vertically. I managed to get the image centered, but the text is not centered vertically. I thought vertical-align:middle would do the trick. Here's the code I have: <div style="background: url('background.png') no-repeat center; width:100%; height:100%; text-align:center;"> <div style="color:#ffffff; text-align: center; vertical-align:middle;" > Some text here. </div> </div> Any ideas?
