    - by DoomStone
    Hello there i'm trying to create a form with Zend_Form that will enable my user to upload a unlited number of files to my site, witch is done by javascript. Something like <script type="text/javascript"> $(document).ready(function(){ var image_uploade_i = 0; $('#upload_more').click(function() { image_uploade_i++; $('#upload_list').append('<div id="image_uploade_id_'+image_uploade_i+'" style="display: none;"><input type="file" name="image[]" /><br /></a>'); $('#image_uploade_id_'+image_uploade_i).slideDown('slow'); }); }); </script> <?=$this->translate('Add images')?> <form action="" method="post" enctype="multipart/form-data"> <div id="upload_list"> <input type="file" name="image[]" /><br /> <input type="file" name="image[]" /><br /> <input type="file" name="image[]" /><br /> </div> <a href="#" id="upload_more"><?=$this->translate('Upload another image')?></a><br /> <input type="submit" name="image_uploade" value="<?=$this->translate('Upload images')?>" /> </form> But i'm am unable to find out how i can create something like this with Zend_From, the only reason i want to use Zend_Form on this thoug is for validation of the uploadet files. $element = new Zend_Form_Element_File('image'); $element->setRequired(true) ->setLabel('Profile image') ->setDestination($store) ->setValueDisabled(true) ->addValidator(new Zend_Validate_File_ImageSize(array( 'minheight' => 100, 'minwidth' => 150, 'maxheight' => 1920, 'maxwidth' => 1200))) // File must be below 1.5 Mb ->addValidator(new Zend_Validate_File_FilesSize(array('max' => 1572864))) ->addValidator(new Zend_Validate_File_IsImage()); If any 1 can help me set this up would i be verry great full :D

  • facebook connect: thumbnail images broken up in FB.Connect.streamPublish pop-up prompt, and on wall

    - by Hoff
    hi there! I'm using facebook connect so that users can publish comments they are leaving on my site on their facebook wall as well. It works as intended, except that in the confirmation pop up, the thumbnail image i provide is broken. Looking at the source, I can see that facebook prepended my image url like this: from: http://www.mysite.com/path/to/my/image.jpg to: http://platform.ak.fbcdn.net/www/app_full_proxy.php?app=303377111175&v=1&size=z&cksum=41a391c9f3a6f3dde2ede9892763c943&src=http%3A%2F%2Fwww.mysite.com%2Fpath%2Fto%2Fmy%2image.jpg The image on the facebook user's wall has the same prepended url, and is also broken for a couple of minutes, after which it's showing up correctly. But obviously, having a broken image in the confirmation window and on your wall for a couple of minutes is not a good experience... Has anybody experienced the same / knows how to work around this issue? Thanks a lot in advance! Martin PS: here's the part of the js call, if it's of any use... attachment = { 'media': [{ 'type': 'image', 'src': 'http://www.mysite.com/path/to/my/image.jpg', 'href': 'http://www.mysite.com/the/current/page' }] }; FB.Connect.streamPublish(user_message, attachment, action_links, target_id, user_message_prompt, fbcallback, false, actor_id)

  • Are there any 3rd Party libraries for image processing in C#?

    - by Gaax
    Just wondering if there's anything out there to help make my project a lot easier to deal with. I'm working on a program that uses the Wiimote and infrared pen (mapped to the mouse) to manipulate images in real time and I'd much rather not have to use all my time figuring out how to make the program resize and rotate images efficiently with the least amount of distortion... I haven't really found anything when searching. Anybody know of any libraries that can help me?

  • Not-quite-JSON string deserialization in Python

    - by cpharmston
    I get the following text as a string from an XML-based REST API 'd':4 'ca':5 'sen':1 'diann':2,6,8 'feinstein':3,7,9 that I'm looking to deserialize into a pretty little Python dictionary: { 'd': [4], 'ca': [5], 'sen': [1], 'diann': [2, 6, 8], 'feinstein': [3, 7, 9] } I'm hoping to avoid using regular expressions or heavy string manipulation, as this format isn't documented and may change. The best I've been able to come up with: members = {} for m in elem.text.split(' '): m = m.split(':') members[m[0].replace("'", '')] = map(int, m[1].split(',')) return members Obviously a terrible approach, but it works, and that's better than anything else I've got right now. Any suggestions on better approaches?

  • Core Data, Bindings, value transformers : crash when saving

    - by Gael
    Hi, I am trying to store a PNG image in a core data store backed by an sqlite database. Since I intend to use this database on an iPhone I can't store NSImage objects directly. I wanted to use bindings and an NSValueTransformer subclass to handle the transcoding from the NSImage (obtained by an Image well on my GUI) to an NSData containing the PNG binary representation of the image. I wrote the following code for the ValueTransformer : + (Class)transformedValueClass { return [NSImage class]; } + (BOOL)allowsReverseTransformation { return YES; } - (id)transformedValue:(id)value { if (value == nil) return nil; return [[[NSImage alloc] initWithData:value] autorelease]; } - (id)reverseTransformedValue:(id)value { if (value == nil) return nil; if(![value isKindOfClass:[NSImage class]]) { NSLog(@"Type mismatch. Expecting NSImage"); } NSBitmapImageRep *bits = [[value representations] objectAtIndex: 0]; NSData *data = [bits representationUsingType:NSPNGFileType properties:nil]; return data; } The model has a transformable property configured with this NSValueTransformer. In Interface Builder a table column and an image well are both bound to this property and both have the proper value transformer name (an image dropped in the image well shows up in the table column). The transformer is registered and called every time an image is added or a row is reloaded (checked with NSLog() calls). The problem arises when I am trying to save the managed objects. The console output shows the error message : [NSImage length]: unrecognized selector sent to instance 0x1004933a0 It seems like core data is using the value transformer to obtain the NSImage back from the NSData and then tries to save the NSImage instead of the NSData. There are probably workarounds such as the one presented in this post but I would really like to understand why my approach is flawn. Thanks in advance for your ideas and explanations.

  • How to scroll and zoom in/out large images on iPhone?

    - by Horace Ho
    I have a large image, size around 30000 (w) x 6000 (h) pixels. You may consider it's like a big map. I assume I need to crop it up into smaller tiles. Questions: what are the right ViewControllers to use? (link) what is the tile strategy? (I put this in another question, as it's not iPhone specific) Requirements: whole image (though cropped) can be scrolled up/down/left/right by swipes zoom in (up to pixel-to-pixel) out (down to screen-fit-by-height) by the 2-finger operation memory efficiency by lazy loading tiles Bonus requirements: automatic scroll, say from left to right slowly and smoothly Thanks!

  • How to deal with color loss on GDI+ Image Resize?

    - by user125775
    Hello All, I am resizing images with C#/GDI+ using the following routing bmpOut = new Bitmap(lnNewWidth, lnNewHeight); Graphics g = Graphics.FromImage(bmpOut); g.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBilinear; g.FillRectangle(Brushes.White, 0, 0, lnNewWidth, lnNewHeight); g.DrawImage(loBMP, 0, 0, lnNewWidth, lnNewHeight); and encoding it with the highest quality. System.Drawing.Imaging.Encoder qualityEncoder = System.Drawing.Imaging.Encoder.Quality; EncoderParameter myEncoderParameter = new EncoderParameter(qualityEncoder, 100L); However, the images that I get have significant loss of color (I am using JPG images only). The quality is perfect, but color is washed away. Do you have any idea what is goingf on? Thanks a lot in advance.

  • PHP Thumbnail image generator works, but consistently awaits 90% of its loadtime! Why?

    - by Sam
    Hi folks, This is the follow-up question from this general page load speed question. This question which will focus only, entirely and specifically on the thumbnail generator PHP code with the question: What's causing the 97% delays on these tiny thumbnails? Measuring only 3 ~ 5 kb each, this is strange indeed! Even after 7 orso bounty-rounds and 100 upvotes, the images are still doing nothing for over 97% of the time. It works allright, but it could be so much faster! ZAM, my pet robot, was so annoyed by not knowing why, he just pulled out some cords! Silly metal box... (I have asked permission from the original author, to put temporarily segments of the code online that I think could be the problem, after which I will remove all code, except the several lines that were the direct cause of this issue here to match the answer. This will be the free opportunity to perfect/speedup his otherwise already to my opinion vert versatile and userfriendly thumbnail generator.)

  • Should image size be defined in the img tag height/width attributes or in CSS?

    - by Benjamin Manns
    Is it better coding practice to define an images size in the img tag's width and height attributes? <img src="images/academia_vs_business.png" width="740" height="382" alt="" /> Or in the CSS style with width/height? <img src="images/academia_vs_business.png" style="width:740px; height:382px;" alt="" /> Or both? <img src="images/academia_vs_business.png" width="740" height="382" style="width:740px; height:382px" alt="" />

  • Application leaking Strings?

    - by Jörg B.
    My .net application does some heavy string loading/manipulation and unfortunately the memory consumption keeps rising and rising and when looking at it with a profiler I see alot of unreleased string instances. Now at one point of time or another I do need all objects t hat do have these string fields, but once done, I could get rid of e.g. the half of it and I Dispose() and set the instances to null, but the Garbage Collector does not to pick that up.. they remain in memory (even after half an hour after disposing etc). Now how do I get properly rid of unneeded strings/object instances in order to release them? They are nowhere referenced anymore (afaik) but e.g. aspose's memory profiler says their distance to the gc's root is '3'?

  • Getting pixel averages of a vector sitting atop a bitmap...

    - by user346511
    I'm currently involved in a hardware project where I am mapping triangular shaped LED to traditional bitmap images. I'd like to overlay a triangle vector onto an image and get the average pixel data within the bounds of that vector. However, I'm unfamiliar with the math needed to calculate this. Does anyone have an algorithm or a link that could send me in the right direction? (I tagged this as Python, which is preferred, but I'd be happy with the general algorithm!) I've created a basic image of what I'm trying to capture here: http://imgur.com/Isjip.gif

  • PHP: problem rendering large images (error 321)

    - by JP19
    Hi ... its me again with a php problem :) Following is part of my PHP script which is rendering JPEG images. ... $tf=$requested_file; $image_type="jpeg"; header("Content-type: image/${image_type}"); $CMD="\$image=imagecreatefrom${image_type}('$tf'); image${image_type}(\$image);"; eval($CMD); exit; ... There is no syntactical error, because above code is working fine for small images, but for large images, it gives: Error 321 (net::ERR_INVALID_CHUNKED_ENCODING): Unknown error. in the browser. To be sure, I created two images using imagemagick from same source image - one resized to 10% of original and other 90%. http://mostpopularsports.net/images/misc/ttt10.jpg works http://mostpopularsports.net/images/misc/ttt90.jpg gives Error 301 in the browser. There is a related question with solution posted by OP here Error writing content through Apache. but I cannot understand how to make the fix. Can someome help me with it? I have looked at the headers in Chrome. For the first request, everything is fine. For the second request - the request headers are all garbled. Both images are jpeg (as they are created from imagemagick. But still to be sure I checked): misc/ttt10.jpg: JPEG image data, JFIF standard 1.01 misc/ttt90.jpg: JPEG image data, JFIF standard 1.01 Finally, the way I fixed is, remove the Transfer-Encoding: chunked header from the response. [This header was sent by apache only when the data was large enough]. (I had an internal proxy, so did it in the proxy script - otherwise one may need to do it in apache settings). There were some good answers and I have selected the one that helped me solve the problem best. thanks JP
