  • performSelectorInBackground: using self.object ?

    - by Emil
    Hey. I am trying to load an image for a custom tableViewCell. The code gets run from the CustomCell-class (CustomCell.h) from [cell performSelectorInBackground:@selector(loadImageFromURL:) withObject:[NSURL URLWithString:urlString]]; in the cellForRowAtIndexPath:-function. Cell gets created here: CustomCell *cell = (CustomCell *) [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil){ NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:self options:nil]; for (id currentObject in topLevelObjects){ if ([currentObject isKindOfClass:[CustomCell class]]){ cell = (CustomCell *) currentObject; break; } } } CustomCell.h: // ... IBOutlet UIImageView *cellImage; } - (void) loadImageFromURL:(NSURL *)url; // … CustomCell.m: - (void) loadImageFromURL:(NSURL *)url { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; NSLog(@"Loading image..."); [loadingImage startAnimating]; [self.cellImage setImageWithURL:url]; [loadingImage stopAnimating]; NSLog(@"Done loading image..."); [pool release]; } setImageWithURL: is a function from the SDWebImage-framework that rs has made. The real error is that the image doesen't show up. EDIT: When I cleared the app's cache, the images didn't show up anymore. EDIT: Seems like URL is nil for some reason. Am I passing the object in the selector correctly? Can you see anything wrong? Thanks.

  • How to pull UIImages from NSData from a socket.

    - by Jus' Wondrin'
    Hey all! I'm using ASyncSocket to move some UIImages from one device over to another. Essentially, on one device I have: NSMutableData *data = UIImageJPEGRepresentation(image, 0.1); if(isRunning){ [sock writeData:data withTimeout:-1 tag:0]; } So a new image will be added to the socket every so often (like a webcam). Then, on the other device, I am calling: [listenSocket readDataWithTimeout:1 tag:0]; which will respond with: - (void)onSocket:(AsyncSocket *)sock didReadData:(NSData *)data withTag:(long)tag { [responseData appendData:data]; [listenSocket readDataWithTimeout:1 tag:0]; } Essentially, what I want to be able to do is have an NSTimer going which will call @selector(PullImages): -(void) PullImages { In here, I want to be able to pull images out of ResponseData. How do I do that? There might not be a complete image yet, there might be multiple images, there might be one and a half images! I want to parse the NSData into each existing image! } Any assistance? Thanks in advance!

  • Three.js: texture to datatexture

    - by Alessandro Pezzato
    I'm trying to implement a delayed webcam viewer in javascript, using Three.js for WebGL capabilities. I need to store frames grabbed from webcam, so they can be shown after some time (some milliseconds to some seconds). I'm able to do this without Three.js, using canvas and getImageData(). You can find an example on jsfidle. I'm trying to find a way to do this without canvas, but using Three.js Texture or DataTexture object. Here an example of what I'm trying. The problem is that I cannot find how to copy the image from a Texture (image is of type HTMLVideoElement) to another. In rotateFrames() function the older frame should be lost and newer should replace, like in a FIFO. But the line frames[i].image = frames[i + 1].image; is just copying the reference, not the texture data. I guess DataTexture should do this, but I'm not able to get a DataTexture out of a Texture or HTMLVideoElement. Any idea?

  • Am I correctly extracting JPEG binary data from this mysqldump?

    - by Glenn
    I have a very old .sql backup of a vbulletin site that I ran around 8 years ago. I am trying to see the file attachments that are stored in the DB. The script below extracts them all and is verified to be JPEG by hex dumping and checking the SOI (start of image) and EOI (end of image) bytes (FFD8 and FFD9, respectively) according to the JPEG wiki page. But when I try to open them with evince, I get this message "Error interpreting JPEG image file (JPEG datastream contains no image)" What could be going on here? Some background info: sqldump is around 8 years old vbulletin 2.x was the software that stored the info most likely php 4 was used most likely mysql 4.0, possibly even 3.x the column datatype these attachments are stored in is mediumtext My Python 3.1 script: #!/usr/bin/env python3.1 import re trim_l = re.compile(b"""^INSERT INTO attachment VALUES\('\d+', '\d+', '\d+', '(.+)""") trim_r = re.compile(b"""(.+)', '\d+', '\d+'\);$""") extractor = re.compile(b"""^(.*(?:\.jpe?g|\.gif|\.bmp))', '(.+)$""") with open('attachments.sql', 'rb') as fh: for line in fh: data = trim_l.findall(line)[0] data = trim_r.findall(data)[0] data = extractor.findall(data) if data: name, data = data[0] try: filename = 'files/%s' % str(name, 'UTF-8') ah = open(filename, 'wb') ah.write(data) except UnicodeDecodeError: continue finally: ah.close() fh.close() update The JPEG wiki page says FF bytes are section markers, with the next byte indicating the section type. I see some that are not listed in the wiki page (specifically, I see a lot of 5C bytes, so FF5C). But the list is of "common markers" so I'm trying to find a more complete list. Any guidance here would also be appreciated.

  • Is there any way to programitically change a Data/ItemTemplate in Silverlight?

    - by Kris Erickson
    So I have a Listbox, which is using an ItemTemplate to display an image. I want to be able to change the size of the displayed image in the ItemTemplate. Through databinding I can change the Width, but the only way I can see how to do this is to add a Property (Say, ImageSize) to the class I am binding to and then change every item in the colleciton to have a new ImageSize. Is there no way to access the property of an item in that Datatemplate? E.g. <navigation:Page.Resources> <DataTemplate x:Key="ListBoxItemTemplate"> <Viewbox Height="100" Width="100"> <Image Source="{Binding Image}"/> </Viewbox> </DataTemplate> </navigation:Page.Resources> <Grid> <ListBox ItemTemplate="{StaticResource ListBoxItemTemplate}" ItemSource="{Binding Collection}"/> </Grid> Is there anyway to set the Width and Height of the viewbox without binding a property to every element in the collection?

  • BitBlting multiple images to buffer

    - by Anonymous
    So I've made a class which draws a transparant image to a buffer. the buffer is a HDC which has been used blackness on. What I am trying to do is draw three images to this buffer. Which means I am using this function three times. After that's done, I output it to the screen (using SRCCOPYing the buffer). But what I get to see is just the third image and blackness. void draw_buffer(HDC buffer, int draw_x, int draw_y) { BitBlt(this-main, draw_x, draw_y, this-img_width, this-img_height, this-image, this-mask_x, this-mask_y, SRCAND); BitBlt(this-main, draw_x, draw_y, this-img_width, this-img_height, this-image, this-img_x, this-img_y, SRCPAINT); BitBlt(buffer, 0, 0, 800, 600, this-main, 0, 0, SRCCOPY); } At initiation, this-main becomes this: this->main = CreateCompatibleDC(GetDC(0)); this->bitmap = CreateCompatibleBitmap(GetDC(0),800,600); SelectObject(this->main, this->bitmap); What is wrong with my code?

  • onmouseover problems with JavaScript (rendered using django and django-imagekit)

    - by Michael Moreno
    I'm using Imagekit. View.py includes: def pics(request): p = Photo.objects.all() return render_to_response('Shots.html', {'p': p}) The following simple code in the template will generate associated images: {% for p in p %} <img src = "{{ p.display.url }}"> <img src = "{{ p.thumbnail_image.url }}"> {% endfor %} I'm attempting to generate a series of thumbnails {{ p.thumbnail_image.url }} which, when mouseover'd, will generate the slightly larger version of the image, {{ p.display.url }} via Javascript. The following code in the template attempts to do so: <html> <head> <HEAD> <script language="Javascript"> { image1 = new Image image2 = new Image image1.src = {{ p.thumbnail_image.url }} image2.src = {{ p.display.url }} </script> </head> <body> {% for p in p %} <a href="" onMouseOver="document.rollover.src= image2.src onMouseOut="document.rollover.src= image1.src"> <img src="{{ p.thumbnail_image.url }}" border=0 name="rollover"></a> {% endfor %} </body> </html> This will display the series of thumbnails, but the larger image will not display when mouseover'd. I believe it has to do with how I'm specifying the variable {{ p.display.url }}.

  • Loading the target of a link in a <DIV> via jQuery's .live event into the same <DIV>??

    - by Martin Pescador
    Hello together I call a certain div from another page with jquery to be loaded into a div on my main page like this: <script type="text/javascript"> $("#scotland").load("http://www.example.com/scotland .gallery"); </script> <div id="scotland"></div> The div I call is a piece of code which is automatically generated by a CMS made simple module, by the way. Now it comes to my problem: The .gallery div I call, looks, a little simplified, like this: <div class="gallery"> <span><img src="http://www.example.com/scotlandimage1.jpg"></span> <span class="imgnavi"><a href="link_to_next_page_with_one_image">Next image</href></span> </div> I want the "next image"-link to load the next page into the .gallery div (it is always a page with one image on it). But what it does, is, it opens the new page http://www.example.com/scotland only. I tried to use jquerys .live event to load the linked page (that would be "scotlandimage2" and the navigation, as you can see in the upper part - not only the image!), but I must have done something wrong. I tried different ways, but never got it to work. This was my last try: $(".imgnavi a").click(function() { var myUrl = $(this).attr("href"); $(".gallery").load(myUrl); return false; }); I have to admit that I am very new to jquery... But does someone know what I did wrong (do I even follow the right handlers?)? Thanks very much in advance! Martin

  • How do I programmatically create a bootable CD?

    - by Nicholas Flynt
    I'm using a barebones tutorial as the basis for an OS I'm working on, and it seems to be an older tutorial: it has be compiling the kernel down to a floppy image, and then loading it with GRUB. Basically, I still want to use GRUB, but I'd like to have my OS run from a CD instead. The main reason is that I don't actually have a real floppy drive available (I'm testing in VirtualBox currently) and I thus have no way to test my OS on real hardware. I've been poking around on the net, and I can find lots of utilities that create a bootable CD from a floppy image, but these all seem to require an actual floppy drive, plus it's not really what I'm looking for. I'd like to be able to end up with a bootable CD during my make step ideally, without needing to first place the image on a floppy, which seems rather pointless. I guess the easy way to answer this: How do I set up GRUB to read my kernel image from a CD? Will I need a special utility to do this from Windows? (The kernel can't compile itself yet, that's not for a looong while) Thanks!

  • Saving NSBitmapImageRep as NSBMPFileType file. Wrong BMP headers and bitmap content

    - by niko34
    I save a NSBitmapImageRep to a BMP file (Snow Leopard). It seems ok when i open it on macos. But it makes an error on my multimedia device (which can show any BMP file from internet). I cannot figure out what is wrong, but when i look inside the file (with the cool hexfiend app on macos), 2 things wrong: the header have a wrong value for the biHeight parameter : 4294966216 (hex=C8FBFFFF) the header have a correct biWidth parameter : 1920 the first pixel in the bitmap content (after 54 bytes headers in BMP format) correspond to the upper left corner of the original image. In the original BMP file and as specified in the BMP format, it should be the down left corner pixel first. To explain the full workflow in my app, i have an NSImageView where i can drag a BMP image. This View is bind to an NSImage. After a drag & drop i have an action to save this image (with some text drawing over it) to a BMP file. Here's the code for saving the new BMP file : CGColorSpaceRefcolorSpace = CGColorSpaceCreateWithName(kCGColorSpaceGenericRGB); CGContextRefcontext = CGBitmapContextCreate(NULL, (int)1920, (int)1080, 8, 4*(int)1920, colorSpace, kCGImageAlphaNoneSkipLast); [duneScreenViewdrawBackgroundWithDuneFolder:self inContext:context inRect:NSMakeRect(0,0,1920,1080) needScale:NO]; if(folderType==DXFolderTypeMovie) { [duneScreenViewdrawSynopsisContentWithDuneFolder:self inContext:context inRect:NSMakeRect(0,0,1920,1080) withScale:1.0]; } CGImageRef backgroundImageRef = CGBitmapContextCreateImage(context); NSBitmapImageRep*bitmapBackgroundImageRef = [[NSBitmapImageRepalloc] initWithCGImage:backgroundImageRef]; NSData*data = [destinationBitmap representationUsingType:NSBMPFileType properties:nil]; [data writeToFile:[NSStringstringWithFormat:@"%@/%@", folderPath,backgroundPath] atomically: YES]; The duneScreenViewdrawSynopsisContentWithDuneFolder method uses CGContextDrawImage to draw the image. The duneScreenViewdrawSynopsis method uses CoreText to draw some text in the same context. Do you know what's wrong?

  • Broken ssl, what to do

    - by TIT
    I have a site and i implemented ssl there. but when i browse it, the security seals dont come. i asked to godaddy, they replaid: Thank you for contacting online support. I cannot replicate the issue you have described. The error you described is caused by the way your site has been designed. If you receive this error, you have a combination of secure and non-secure objects on the page. For example, if your secure website was https://www.domain.tld and you added an object (an image, script, flash file, etc.) to that page that was located at http://www.domain.tld/image.jpg, you would break the seal. You will need to change your design to link to objects using https (ie https://www.domain.tld/image.jpg) or modify your site design to use relative paths (/image.jpg). This error can only be corrected by modifying your site design. Please contact your web designer or the manufacturer of your web design software if you require additional assistance modifying your site design. but the problem is i made everything,all my images javascripts are unders https, but the seal still not coming, saying: some content insecure. what is the problem.

  • Valueurl Binding On Large Arrays Causes Sluggish User Interface

    - by Hooligancat
    I have a large data set (some 3500 objects) that returns from a remote server via HTTP. Currently the data is being presented in an NSCollectionView. One aspect of the data is a path pack to the server for a small image that represents the data (think thumbnail for simplicity). Bindings works fantastically for the data that is already returned, and binding the image via a valueurl binding is easy to do. However, the user interface is very sluggish when scrolling through the data set - which makes me think that the NSCollectionView is retrieving all the image data instead of just the image data used to display the currently viewable images. I was under the impression that Cocoa controls were smart enough to only retrieve data for the information that is actually being output to the user interface through lazy loading. This certainly seems to be the case with NSTableView - but I could be misguided on this thought. Should valueurl binding act lazily and, moreover, should it act lazily in an NSCollectionView? I could create a caching mechanism (in fact I already have such a thing in place for another application - see my post here if you are interested http://stackoverflow.com/questions/1740209/populating-nsimage-with-data-from-an-asynchronous-nsurlconnection) but I really don't want to go this route if I don't have to for this specific implementation as the user could potentially change data sets often and may only want small sub-sets of the data. Any suggested approaches? Thanks!

  • Form not updating usercontrol

    - by user328259
    From the post "Growing user control not updating"... Using C#, .Net 2.0 in a Windows environment. UserControl1 - draws cells to a bitmap buffer dependent upon NumberOfCells property UserControl2 - panel contains UserControl1 which displays vertical scroll when necessary; also contains NumberOfCells which sets UserControl1's NumberOfCells. Formf1 - contains NumericUpDown controls (just increments) which updates the UserControl2 - suppose to! When I increment the control on the form by say 20, UserControl1 adds the necessary cells, UserControl2 displays the vertical scroll bar accordingly, BUT the form does not 'redraw' to the updated/correct image!! Meaning, after I increment by 20, cells are added, vertical scrool bar added... but the image shown is just everything else expanding. I reset the control to scoll to the very TOP and the scrolling works, but the image is still staic... UNTIL I resize my form, more specifically, when I change it from maximize to window or vice versa!!! What can I do to 'reset/redraw' the correct image???? Thank you in advance. Lawrence

  • Visual Studio 2008 Web Project problem with PNG files

    - by NoCarrier
    I've added a PNG file to a directory in my VS2k8 webforms project, and when I run the app, it refuses to render my image - it even knows the dimensions but renders a box with a red X. Oddly enough, if I double click the PNG file within VS2k8, it opens up in the IDE and displays fine (but only within the IDE). Does anyone have any clues? The path is correct.. I just have a basic default.aspx page with this in the body <img src="img/logo.png" /> if i navigate to img/logo.png in the browser, it shows a box with the same dimensions as my image, but a red x. Its finding the image, just not rendering it. It's showing up in IE running under the vs2k8 web server (localhost:5512/default.aspx) I've dropped a JPG in the same directory, and it shows up just fine. I'm not sure what type of PNG it is, but here is the kicker.... If i make an HTML file that references that image, copy both this HTML file and PNG file to my webserver (or just double click on the HTML page), it comes up JUST FINE. Its leading me to believe that the Visual Studio web server may not recognize PNG files (at least this one) properly?

  • ScrollView content async downloading problem

    - by Newbee
    Hi! I have UIScrollView with lots of UIImageView inside. In the loadView method I assign some temporary image for each of subview UIImageView images and starts several threads to async download images from internet. Each thread downloads and assign images as follows: NSData *data = [NSData dataWithContentsOfURL:URL]; UIImage *img = [UIImage imageWithData:data]; img_view.image = img; Here is the problem - I expects picture will changed after each image downloaded by I can see only temporary images until all images will downloads. UIScrollView still interact while images downloads - I can scroll temporary images inside it and see scrollers and nothing blocks run loop, but downloaded images doesn't updates.. What I tried to do: Call sleep() in the download thread -- not helps. Call setNeedsDisplay for each ImageView inside ScrollView and for ScrollView -- not helps. What's wrong ? Thanks. Update. I tried some experiments with number of threads and number of images to download. Now I'm sure -- images redraws only when thread finished. For example - if I load 100 images with one thread -- picture updates one time after all images downloads. If I increase number of threads to 10 -- picture updates 10 times -- 10 images appears per update. One more update. I fixed problem by staring new thread from the downloading threads each time one image downloaded and exit current thread (instead of download several images in one thread in the cycle and exit thread only when all downloaded). Obviously it's not a good solution and there must be right approach.

    i'm trying out libgdx as an opengl wrapper , and i have some issues with its graphical rendering : for some reason , all images (textures) on android device look a little blurred using libgdx . this also includes text (font) . however, for normal images , even though i show the entire image , i expect it to look as sharp as i see it on a computer , especially if i have such a good screen on the device (it's galaxy nexus) . i've tried to set the anti-aliasing off , by using the next code : final AndroidApplicationConfiguration androidApplicationConfiguration=new AndroidApplicationConfiguration(); androidApplicationConfiguration.numSamples=0; //tried the value of 1 too. ... i've also tried to set the scaling method to various methods , but with no luck. example: texture.setFilter(TextureFilter.Nearest,TextureFilter.Nearest); as a test , i've found a sharp image that is exactly the same as the seen resolution on the device (720x1184 for galaxy nexus , because of the buttons bar) , and i've put it to be on the background of the libgdx app . of course , i had to add extra blank space in order for the texute to be loaded , so the final size of the image (which will include content and empty space) is still a power of 2 for both width and height (1024x2048 in my case) . on the desktop app , it look ok . on the device , it looked blurred. a weird thing that i've noticed is that when i change the device's orientation (horizontal <= vertical) , for the very short time before the rotating animation starts , i see both the image and the text very well . can anyone please help me?

  • Index out of bounds exception while iterating through a List<string>.

    - by Sergio Tapia
    I have a List of the location of images on a folder. I have five pictureBoxes that emulate a coverflow type area for users to skim through the images of a given folder. I know that the error is fired because the first image in the collection is set to the first picturebox, then if I click on cycleLeft(), there is a negative number. How can I account for this? For example, if the first image in the List is already set to the farthest left and someone clicks flip left, have that first image put on the last position of the list. Any guidance? private void leftArrow_Click(object sender, EventArgs e) { cycleImagesLeft(); } private void rightArrow_Click(object sender, EventArgs e) { cycleImagesRight(); } public void cycleImagesLeft() { //imageThree is the center image, that's why I use it as a frame of reference. int currentImage = pictures.IndexOf(imageThree.ImageLocation); imageOne.ImageLocation = pictures[currentImage - 3]; imageTwo.ImageLocation = pictures[currentImage - 2]; imageThree.ImageLocation = pictures[currentImage - 1]; imageFour.ImageLocation = pictures[currentImage]; imageFive.ImageLocation = pictures[currentImage + 1]; } public void cycleImagesRight() { int currentImage = pictures.IndexOf(imageThree.ImageLocation); imageOne.ImageLocation = pictures[currentImage - 1]; imageTwo.ImageLocation = pictures[currentImage]; imageThree.ImageLocation = pictures[currentImage + 1]; imageFour.ImageLocation = pictures[currentImage + 2]; imageFive.ImageLocation = pictures[currentImage + 3]; }

  • Why aren't my objects sorting with sortedArrayUsingDescriptors?

    - by clozach
    I expected the code below to return the objects in imageSet as a sorted array. Instead, there's no difference in the ordering before and after. NSSortDescriptor *descriptor = [[NSSortDescriptor alloc] initWithKey:@"imageID" ascending:YES]; NSSet *imageSet = collection.images; for (CBImage *image in imageSet) { NSLog(@"imageID in Set: %@",image.imageID); } NSArray *imageArray = [[imageSet allObjects] sortedArrayUsingDescriptors:(descriptor, nil)]; [descriptor release]; for (CBImage *image in imageArray) { NSLog(@"imageID in Array: %@",image.imageID); } Fwiw, CBImage is defined in my core data model. I don't know why sorting on managed objects would work any differently than on "regular" objects, but maybe it matters. As proof that @"imageID" should work as the key for the descriptor, here's what the two log loops above output for one of the sets I'm iterating through: 2010-05-05 00:49:52.876 Cover Browser[38678:207] imageID in Array: 360339 2010-05-05 00:49:52.876 Cover Browser[38678:207] imageID in Array: 360337 2010-05-05 00:49:52.877 Cover Browser[38678:207] imageID in Array: 360338 2010-05-05 00:49:52.878 Cover Browser[38678:207] imageID in Array: 360336 2010-05-05 00:49:52.879 Cover Browser[38678:207] imageID in Array: 360335 ... For extra credit, I'd love to get a general solution to troubleshooting NSSortDescriptor troubles (esp. if it also applies to troubleshooting NSPredicate). The functionality of these things seems totally opaque to me and consequently debugging takes forever.

  • Debugging PHP Mail() and/or PHPMailer

    - by Agos
    Hi, I'm quite stuck with a problem sending mail from a PHP script. Some data: Shared hosting, no SSH access, only hosting provider panel PHP version 5.2.5 Last year I built a site which had no problems sending mail with the same hosting Let's say the domain is “domain.com” and my private address is “[email protected]” for anonimity's sake in the following code. Here's the code: <?php error_reporting(E_ALL); ini_set("display_errors", 1); $to = "[email protected]"; $subject = "Hi"; $body = "Test 1\nTest 2\nTest 3"; $headers = 'From: [email protected]' . "\r\n" . 'errors-to: [email protected]' . "\r\n" . 'X-Mailer: PHP/' . phpversion(); if (mail($to, $subject, $body, $headers)) { echo("Message successfully sent"); } else { echo("Message sending failed"); } require('class.phpmailer.php'); $message = "Hello world"; $mail = new PHPMailer(); $mail->CharSet = "UTF-8"; $mail->AddAddress("[email protected]", "Agos"); $mail->SetFrom("[email protected]","My Site"); $mail->Subject = "Test Message"; $mail->Body = $message; $mail->Send(); ?> And here is what I get: Message sending failed 'ai' = 'application/postscript', 'eps' = 'application/postscript', 'ps' = 'application/postscript', 'smi' = 'application/smil', 'smil' = 'application/smil', 'mif' = 'application/vnd.mif', 'xls' = 'application/vnd.ms-excel', 'ppt' = 'application/vnd.ms-powerpoint', 'wbxml' = 'application/vnd.wap.wbxml', 'wmlc' = 'application/vnd.wap.wmlc', 'dcr' = 'application/x-director', 'dir' = 'application/x-director', 'dxr' = 'application/x-director', 'dvi' = 'application/x-dvi', 'gtar' = 'application/x-gtar', 'php' = 'application/x-httpd-php', 'php4' = 'application/x-httpd-php', 'php3' = 'application/x-httpd-php', 'phtml' = 'application/x-httpd-php', 'phps' = 'application/x-httpd-php-source', 'js' = 'application/x-javascript', 'swf' = 'application/x-shockwave-flash', 'sit' = 'application/x-stuffit', 'tar' = 'application/x-tar', 'tgz' = 'application/x-tar', 'xhtml' = 'application/xhtml+xml', 'xht' = 'application/xhtml+xml', 'zip' = 'application/zip', 'mid' = 'audio/midi', 'midi' = 'audio/midi', 'mpga' = 'audio/mpeg', 'mp2' = 'audio/mpeg', 'mp3' = 'audio/mpeg', 'aif' = 'audio/x-aiff', 'aiff' = 'audio/x-aiff', 'aifc' = 'audio/x-aiff', 'ram' = 'audio/x-pn-realaudio', 'rm' = 'audio/x-pn-realaudio', 'rpm' = 'audio/x-pn-realaudio-plugin', 'ra' = 'audio/x-realaudio', 'rv' = 'video/vnd.rn-realvideo', 'wav' = 'audio/x-wav', 'bmp' = 'image/bmp', 'gif' = 'image/gif', 'jpeg' = 'image/jpeg', 'jpg' = 'image/jpeg', 'jpe' = 'image/jpeg', 'png' = 'image/png', 'tiff' = 'image/tiff', 'tif' = 'image/tiff', 'css' = 'text/css', 'html' = 'text/html', 'htm' = 'text/html', 'shtml' = 'text/html', 'txt' = 'text/plain', 'text' = 'text/plain', 'log' = 'text/plain', 'rtx' = 'text/richtext', 'rtf' = 'text/rtf', 'xml' = 'text/xml', 'xsl' = 'text/xml', 'mpeg' = 'video/mpeg', 'mpg' = 'video/mpeg', 'mpe' = 'video/mpeg', 'qt' = 'video/quicktime', 'mov' = 'video/quicktime', 'avi' = 'video/x-msvideo', 'movie' = 'video/x-sgi-movie', 'doc' = 'application/msword', 'word' = 'application/msword', 'xl' = 'application/excel', 'eml' = 'message/rfc822' ); return (!isset($mimes[strtolower($ext)])) ?
