• PHP/GD - Cropping and Resizing Images

  - by Alix Axel

  I've coded a function that crops an image to a given aspect ratio and finally then resizes it and outputs it as JPG: <?php function Image($image, $crop = null, $size = null) { $image = ImageCreateFromString(file_get_contents($image)); if (is_resource($image) === true) { $x = 0; $y = 0; $width = imagesx($image); $height = imagesy($image); /* CROP (Aspect Ratio) Section */ if (is_null($crop) === true) { $crop = array($width, $height); } else { $crop = array_filter(explode(':', $crop)); if (empty($crop) === true) { $crop = array($width, $height); } else { if ((empty($crop[0]) === true) || (is_numeric($crop[0]) === false)) { $crop[0] = $crop[1]; } else if ((empty($crop[1]) === true) || (is_numeric($crop[1]) === false)) { $crop[1] = $crop[0]; } } $ratio = array ( 0 => $width / $height, 1 => $crop[0] / $crop[1], ); if ($ratio[0] > $ratio[1]) { $width = $height * $ratio[1]; $x = (imagesx($image) - $width) / 2; } else if ($ratio[0] < $ratio[1]) { $height = $width / $ratio[1]; $y = (imagesy($image) - $height) / 2; } /* How can I skip (join) this operation with the one in the Resize Section? */ $result = ImageCreateTrueColor($width, $height); if (is_resource($result) === true) { ImageSaveAlpha($result, true); ImageAlphaBlending($result, false); ImageFill($result, 0, 0, ImageColorAllocateAlpha($result, 255, 255, 255, 127)); ImageCopyResampled($result, $image, 0, 0, $x, $y, $width, $height, $width, $height); $image = $result; } } /* Resize Section */ if (is_null($size) === true) { $size = array(imagesx($image), imagesy($image)); } else { $size = array_filter(explode('x', $size)); if (empty($size) === true) { $size = array(imagesx($image), imagesy($image)); } else { if ((empty($size[0]) === true) || (is_numeric($size[0]) === false)) { $size[0] = round($size[1] * imagesx($image) / imagesy($image)); } else if ((empty($size[1]) === true) || (is_numeric($size[1]) === false)) { $size[1] = round($size[0] * imagesy($image) / imagesx($image)); } } } $result = ImageCreateTrueColor($size[0], $size[1]); if (is_resource($result) === true) { ImageSaveAlpha($result, true); ImageAlphaBlending($result, true); ImageFill($result, 0, 0, ImageColorAllocate($result, 255, 255, 255)); ImageCopyResampled($result, $image, 0, 0, 0, 0, $size[0], $size[1], imagesx($image), imagesy($image)); header('Content-Type: image/jpeg'); ImageInterlace($result, true); ImageJPEG($result, null, 90); } } return false; } ?> The function works as expected but I'm creating a non-required GD image resource, how can I fix it? I've tried joining both calls but I must be doing some miscalculations. <?php /* Usage Examples */ Image('http://upload.wikimedia.org/wikipedia/commons/4/47/PNG_transparency_demonstration_1.png', '1:1', '600x'); Image('http://upload.wikimedia.org/wikipedia/commons/4/47/PNG_transparency_demonstration_1.png', '2:1', '600x'); Image('http://upload.wikimedia.org/wikipedia/commons/4/47/PNG_transparency_demonstration_1.png', '2:', '250x300'); ?> Any help is greatly appreciated, thanks.

• Is using the .NET Image Conversion enough?

  - by contactmatt

  I've seen a lot of people try to code their own image conversion techniques. It often seems to be very complicated, and ends up using GDI+ function calls, and manipulating bits of the image. This has got me wondering if I am missing something in the simplicity of .NET's image conversion call when saving an image. Here's the code I have: Bitmap tempBmp = new Bitmap("c:\temp\img.jpg"); Bitmap bmp = new Bitmap(tempBmp, 800, 600); bmp.Save(c:\temp\img.bmp, //extension depends on format ImageFormat.Bmp) //These are all the ImageFormats I allow conversion to within the program. Ignore the syntax for a second ;) ImageFormat.Gif) //or ImageFormat.Jpeg) //or ImageFormat.Png) //or ImageFormat.Tiff) //or ImageFormat.Wmf) //or ImageFormat.Bmp)//or ); This is all I'm doing in my image conversion. Just setting the location of where the image should be saved, and passing it an ImageFormat type. I've tested it the best I can, but I'm wondering if I am missing anything in this simple format conversion, or if this is sufficient?

• PHP image watermark only displaying image on page

  - by Satch3000

  I am testing a script where I watermark an image in my webpage. The script works fine and the image is watermark but my problem is that only the image is displayed on the page. As soon as I add the script to my page it's like the web page is converted to the image that I'm watermarking. I think it's because of header("content-type: image/jpeg"); from the code. I need to watermark the image on my webpage but I also need the rest of my webpage to be displayed too. How is this done? I'm quite confused on how this works. The script I'm using is from here Here's the code I'm using: <?php $main_img = "Porsche_911_996_Carrera_4S.jpg"; // main big photo / picture $watermark_img = "watermark.gif"; // use GIF or PNG, JPEG has no tranparency support $padding = 3; // distance to border in pixels for watermark image $opacity = 100; // image opacity for transparent watermark $watermark = imagecreatefromgif($watermark_img); // create watermark $image = imagecreatefromjpeg($main_img); // create main graphic if(!$image || !$watermark) die("Error: main image or watermark could not be loaded!"); $watermark_size = getimagesize($watermark_img); $watermark_width = $watermark_size[0]; $watermark_height = $watermark_size[1]; $image_size = getimagesize($main_img); $dest_x = $image_size[0] - $watermark_width - $padding; $dest_y = $image_size[1] - $watermark_height - $padding; // copy watermark on main image imagecopymerge($image, $watermark, $dest_x, $dest_y, 0, 0, $watermark_width, $watermark_height, $opacity); // print image to screen header("content-type: image/jpeg"); imagejpeg($image); imagedestroy($image); imagedestroy($watermark); ?> NOTE: I'm getting the image path from the database so I cannot hardcode the image filename as it's dynamic.

• Blurred image recovery?

  - by m0s

  I have pictures of handwritten text and some of them are blurred, because the camera was shaky. If someone could point out any techniques that I can use to bring it to readable quality would be great. It is really a closeup, and I'm pretty sure it is doable. If you can recommend a specialized software or you know some techniques in photo-shop or any other software that would help please comment.

• Helping to Reduce Page Compression Failures Rate

  - by Vasil Dimov

  When InnoDB compresses a page it needs the result to fit into its predetermined compressed page size (specified with KEY_BLOCK_SIZE). When the result does not fit we call that a compression failure. In this case InnoDB needs to split up the page and try to compress again. That said, compression failures are bad for performance and should be minimized.Whether the result of the compression will fit largely depends on the data being compressed and some tables and/or indexes may contain more compressible data than others. And so it would be nice if the compression failure rate, along with other compression stats, could be monitored on a per table or even on a per index basis, wouldn't it?This is where the new INFORMATION_SCHEMA table in MySQL 5.6 kicks in. INFORMATION_SCHEMA.INNODB_CMP_PER_INDEX provides exactly this helpful information. It contains the following fields: +-----------------+--------------+------+ | Field | Type | Null | +-----------------+--------------+------+ | database_name | varchar(192) | NO | | table_name | varchar(192) | NO | | index_name | varchar(192) | NO | | compress_ops | int(11) | NO | | compress_ops_ok | int(11) | NO | | compress_time | int(11) | NO | | uncompress_ops | int(11) | NO | | uncompress_time | int(11) | NO | +-----------------+--------------+------+ similarly to INFORMATION_SCHEMA.INNODB_CMP, but this time the data is grouped by "database_name,table_name,index_name" instead of by "page_size".So a query like SELECT database_name, table_name, index_name, compress_ops - compress_ops_ok AS failures FROM information_schema.innodb_cmp_per_index ORDER BY failures DESC; would reveal the most problematic tables and indexes that have the highest compression failure rate.From there on the way to improving performance would be to try to increase the compressed page size or change the structure of the table/indexes or the data being stored and see if it will have a positive impact on performance.

• Using VB6 + WSH with Windows Compression

  - by OneNerd

  Having trouble with WSH and Windows Compression. My goal is to be able to zip up files (not folders, but individual files from various locations, which I have stored in an array) using the built-in Windows Compression. I am using VB6. Here is my routine (vb6 code): Dim objShell Dim objFolder Set objShell = CreateObject("Shell.Application") Set objFolder = objShell.namespace(savePath & "\export.zip") ' -- ' loop through array holding files to zip For i = 0 To filePointer objFolder.CopyHere (filesToZip(i)) Next ' -- Set objShell = Nothing Set objFolder = Nothing It works, but issues arise when there are more than a few files. I start getting errors from Windows (presumably, its calling the compression too fast, and the zip file is locked). I cant seem to figure out how to WAIT until the COPYHERE function completes before calling the next one to avoid issues. Does anyone have any experience with this? Thanks -

• Rotating images with PHP reduces quality especially over about 10-20 actions

  - by Dylan Cross

  I am using this code below to rotate my jpeg images, the problem is that after around 10-20 times of rotating the image the image is dramatically lower quality, especially blue skies and such, my question is how can I keep these images the same high quality image? There must be a way. I mean, i keep the original image on the server for each image uploaded, and I don't do anything to that, so if need be it, I guess I could always come up with some way of using that over whenever possible.. But would rather not have to. $source = imagecreatefromjpeg($filename); $rotate = imagerotate($source, 90, 0); imagejpeg($rotate, $filename ,100);

• Issue with WIC image resizing on ASP.NET MVC 2

  - by Dave

  I am attempting to implement image resizing on user uploads in ASP.NET MVC 2 using a version of the method found: here on asp.net. This works great on my dev machine, but as soon as I put it on my production machine, I start getting the error 'Exception from HRESULT: 0x88982F60' which is supposed to mean that there is an issue decoding the image. However, when I use WICExplorer to open the image, it looks ok. I've also tried this with dozens of images of various sources and still get the error (though possible, I doubt all of them are corrupted). Here is the relevant code (with my debugging statements in there): MVC Controller [Authorize, HttpPost] public ActionResult Upload(string file) { //Check file extension string fx = file.Substring(file.LastIndexOf('.')).ToLowerInvariant(); string key; if (ConfigurationManager.AppSettings["ImageExtensions"].Contains(fx)) { key = Guid.NewGuid().ToString() + fx; } else { return Json("extension not found"); } //Check file size if (Request.ContentLength <= Convert.ToInt32(ConfigurationManager.AppSettings["MinImageSize"]) || Request.ContentLength >= Convert.ToInt32(ConfigurationManager.AppSettings["MaxImageSize"])) { return Json("content length out of bounds: " + Request.ContentLength); } ImageResizerResult irr, irr2; //Check if this image is coming from FF, Chrome or Safari (XHR) HttpPostedFileBase hpf = null; if (Request.Files.Count <= 0) { //Scale and encode image and thumbnail irr = ImageResizer.CreateMaxSizeImage(Request.InputStream); irr2 = ImageResizer.CreateThumbnail(Request.InputStream); } //Or IE else { hpf = Request.Files[0] as HttpPostedFileBase; if (hpf.ContentLength == 0) return Json("hpf.length = 0"); //Scale and encode image and thumbnail irr = ImageResizer.CreateMaxSizeImage(hpf.InputStream); irr2 = ImageResizer.CreateThumbnail(hpf.InputStream); } //Check if image and thumbnail encoded and scaled correctly if (irr == null || irr.output == null || irr2 == null || irr2.output == null) { if (irr != null && irr.output != null) irr.output.Dispose(); if (irr2 != null && irr2.output != null) irr2.output.Dispose(); if(irr == null) return Json("irr null"); if (irr2 == null) return Json("irr2 null"); if (irr.output == null) return Json("irr.output null. irr.error = " + irr.error); if (irr2.output == null) return Json("irr2.output null. irr2.error = " + irr2.error); } if (irr.output.Length > Convert.ToInt32(ConfigurationManager.AppSettings["MaxImageSize"]) || irr2.output.Length > Convert.ToInt32(ConfigurationManager.AppSettings["MaxImageSize"])) { if(irr.output.Length > Convert.ToInt32(ConfigurationManager.AppSettings["MaxImageSize"])) return Json("irr.output.Length > maximage size. irr.output.Length = " + irr.output.Length + ", irr.error = " + irr.error); return Json("irr2.output.Length > maximage size. irr2.output.Length = " + irr2.output.Length + ", irr2.error = " + irr2.error); } //Store scaled and encoded image and thumbnail .... return Json("success"); } The code is always failing when checking if the output stream is null (i.e. irr.output == null is true).

• SSRS: Report loading external images, image not found, can I hide the image control

  - by Nauman

  My SSRS report loads logo images for each customer from a customer number specific folder on the report server. I write an expression, to form my URL to the image based on th customer number. ..."http://localhost/images/" + iCustomerNumber.ToString() + "/logo.gif" I am able to get this working, but the problem I face is, when a particular customer doesn't has an image, then my report shows a red X mark in place of the logo. In this case, I expect to hide the image control itself. Any thoughts???? The other dirty solution will be to ensure that each customer specific folder has the designated image! even if there is no logo for a customer, I'll place a blank.gif or a spacer.gif of probably a square pixel in dimension!.

• Image Processing, joining the small images to form the main image

  - by n0idea

  Good morning everyone, Actually I'm having a small issue in image processing and I'm in need of some help. First of all, let me explain what i want to do, i have an image that was split into 4 other small images. I currently have like 6 small images that i need to figure out which ones are part of the real image. Second, what i currently know is that that i should compare these images edges or last column with the first column of the other image. I'm not sure yet what exactly should be done, anyone is able to put me on the same tracks, with some detailed hints and how to compare the edges of 2 images. Some links and example codes will be help full. One more thing, how am i able to read .Raw images using java, c# or python ?

• turning text into image - PHP/GD - save image

  - by Phil Jackson

  Hi, I'm using this script to simply create an image from text. What I would like to know is how to save the image instead of printing straight to browser; // an email address in a string $string = $post[$key]; // some variables to set $font = 4; $width = ImageFontWidth($font) * strlen($string); $height = ImageFontHeight($font); // lets begin by creating an image $im = @imagecreatetruecolor ($width,$height); //white background $background_color = imagecolorallocate ($im, 255, 255, 255); //black text $text_color = imagecolorallocate ($im, 0, 0, 0); // put it all together $image = imagestring ($im, $font, 0, 0, $string, $text_color); I know its probably just one line of code at the end but im not sure which GD function to use. Any help would be much appreciated, Regards, Phil.

• Dynamically reducing image dimension as well as image size in C#

  - by hanesjw

  I have an image gallery that is created using a repeater control. The repeater gets bound inside my code behind file to a table that contains various image paths. The images in my repeater are populated like this <img src='<%# Eval("PicturePath")' %>' height='200px' width='150px'/> (or something along those lines, I don't recall the exact syntax) The problem is sometimes the images themselves are massive so the load times are a little ridiculous. And populating a 150x200px image definitely should not require a 3MB file. Is there a way I can not only change the image dimensions, but shrink the file size down as well? Thanks!

• SQL Server 2008 Compression

  - by Peter Larsson

  Hi! Today I am going to talk about compression in SQL Server 2008. The data warehouse I currently design and develop holds historical data back to 1973. The data warehouse will have an other blog post laster due to it's complexity. However, the server has 60GB of memory (of which 48 is dedicated to SQL Server service), so all data didn't fit in memory and the SAN is not the fastest one around. So I decided to give compression a go, since we use Enterprise Edition anyway. This is the code I use to compress all tables with PAGE compression. DECLARE @SQL VARCHAR(MAX)   DECLARE curTables CURSOR FOR             SELECT 'ALTER TABLE ' + QUOTENAME(OBJECT_SCHEMA_NAME(object_id))                     + '.' + QUOTENAME(OBJECT_NAME(object_id))                     + ' REBUILD PARTITION = ALL WITH (DATA_COMPRESSION = PAGE)'             FROM    sys.tables   OPEN    curTables   FETCH   NEXT FROM    curTables INTO    @SQL   WHILE @@FETCH_STATUS = 0     BEGIN         IF @SQL IS NOT NULL             RAISERROR(@SQL, 10, 1) WITH NOWAIT           FETCH   NEXT         FROM    curTables         INTO    @SQL     END   CLOSE       curTables DEALLOCATE  curTables Copy and paste the result to a new code window and execute the statements. One thing I noticed when doing this, is that the database grows with the same size as the table. If the database cannot grow this size, the operation fails. For me, I first ended up with orphaned connection. Not good. And this is the code I use to create the index compression statements DECLARE @SQL VARCHAR(MAX)   DECLARE curIndexes CURSOR FOR             SELECT      'ALTER INDEX ' + QUOTENAME(name)                         + ' ON '                         + QUOTENAME(OBJECT_SCHEMA_NAME(object_id))                         + '.'                         + QUOTENAME(OBJECT_NAME(object_id))                         + ' REBUILD PARTITION = ALL WITH (FILLFACTOR = 100, DATA_COMPRESSION = PAGE)'             FROM        sys.indexes             WHERE       OBJECTPROPERTY(object_id, 'IsMSShipped') = 0                         AND OBJECTPROPERTY(object_id, 'IsTable') = 1             ORDER BY    CASE type_desc                             WHEN 'CLUSTERED' THEN 1                             ELSE 2                         END   OPEN    curIndexes   FETCH   NEXT FROM    curIndexes INTO    @SQL   WHILE @@FETCH_STATUS = 0     BEGIN         IF @SQL IS NOT NULL             RAISERROR(@SQL, 10, 1) WITH NOWAIT           FETCH   NEXT         FROM    curIndexes         INTO    @SQL     END   CLOSE       curIndexes DEALLOCATE  curIndexes When this was done, I noticed that the 90GB database now only was 17GB. And most important, complete database now could reside in memory! After this I took care of the administrative tasks, backups. Here I copied the code from Management Studio because I didn't want to give too much time for this. The code looks like (notice the compression option). BACKUP DATABASE [Yoda] TO              DISK = N'D:\Fileshare\Backup\Yoda.bak' WITH            NOFORMAT,                 INIT,                 NAME = N'Yoda - Full Database Backup',                 SKIP,                 NOREWIND,                 NOUNLOAD,                 COMPRESSION,                 STATS = 10,                 CHECKSUM GO   DECLARE @BackupSetID INT   SELECT  @BackupSetID = Position FROM    msdb..backupset WHERE   database_name = N'Yoda'         AND backup_set_id =(SELECT MAX(backup_set_id) FROM msdb..backupset WHERE database_name = N'Yoda')   IF @BackupSetID IS NULL     RAISERROR(N'Verify failed. Backup information for database ''Yoda'' not found.', 16, 1)   RESTORE VERIFYONLY FROM    DISK = N'D:\Fileshare\Backup\Yoda.bak' WITH    FILE = @BackupSetID,         NOUNLOAD,         NOREWIND GO After running the backup, the file size was even more reduced due to the zip-like compression algorithm used in SQL Server 2008. The file size? Only 9 GB. //Peso

• How To Get Web Site Thumbnail Image In ASP.NET

  - by SAMIR BHOGAYTA

  Overview One very common requirement of many web applications is to display a thumbnail image of a web site. A typical example is to provide a link to a dynamic website displaying its current thumbnail image, or displaying images of websites with their links as a result of search (I love to see it on Google). Microsoft .NET Framework 2.0 makes it quite easier to do it in a ASP.NET application. Background In order to generate image of a web page, first we need to load the web page to get their html code, and then this html needs to be rendered in a web browser. After that, a screen shot can be taken easily. I think there is no easier way to do this. Before .NET framework 2.0 it was quite difficult to use a web browser in C# or VB.NET because we either have to use COM+ interoperability or third party controls which becomes headache later. WebBrowser control in .NET framework 2.0 In .NET framework 2.0 we have a new Windows Forms WebBrowser control which is a wrapper around old shwdoc.dll. All you really need to do is to drop a WebBrowser control from your Toolbox on your form in .NET framework 2.0. If you have not used WebBrowser control yet, it's quite easy to use and very consistent with other Windows Forms controls. Some important methods of WebBrowser control are. public bool GoBack(); public bool GoForward(); public void GoHome(); public void GoSearch(); public void Navigate(Uri url); public void DrawToBitmap(Bitmap bitmap, Rectangle targetBounds); These methods are self explanatory with their names like Navigate function which redirects browser to provided URL. It also has a number of useful overloads. The DrawToBitmap (inherited from Control) draws the current image of WebBrowser to the provided bitmap. Using WebBrowser control in ASP.NET 2.0 The Solution Let's start to implement the solution which we discussed above. First we will define a static method to get the web site thumbnail image. public static Bitmap GetWebSiteThumbnail(string Url, int BrowserWidth, int BrowserHeight, int ThumbnailWidth, int ThumbnailHeight) { WebsiteThumbnailImage thumbnailGenerator = new WebsiteThumbnailImage(Url, BrowserWidth, BrowserHeight, ThumbnailWidth, ThumbnailHeight); return thumbnailGenerator.GenerateWebSiteThumbnailImage(); } The WebsiteThumbnailImage class will have a public method named GenerateWebSiteThumbnailImage which will generate the website thumbnail image in a separate STA thread and wait for the thread to exit. In this case, I decided to Join method of Thread class to block the initial calling thread until the bitmap is actually available, and then return the generated web site thumbnail. public Bitmap GenerateWebSiteThumbnailImage() { Thread m_thread = new Thread(new ThreadStart(_GenerateWebSiteThumbnailImage)); m_thread.SetApartmentState(ApartmentState.STA); m_thread.Start(); m_thread.Join(); return m_Bitmap; } The _GenerateWebSiteThumbnailImage will create a WebBrowser control object and navigate to the provided Url. We also register for the DocumentCompleted event of the web browser control to take screen shot of the web page. To pass the flow to the other controls we need to perform a method call to Application.DoEvents(); and wait for the completion of the navigation until the browser state changes to Complete in a loop. private void _GenerateWebSiteThumbnailImage() { WebBrowser m_WebBrowser = new WebBrowser(); m_WebBrowser.ScrollBarsEnabled = false; m_WebBrowser.Navigate(m_Url); m_WebBrowser.DocumentCompleted += new WebBrowserDocument CompletedEventHandler(WebBrowser_DocumentCompleted); while (m_WebBrowser.ReadyState != WebBrowserReadyState.Complete) Application.DoEvents(); m_WebBrowser.Dispose(); } The DocumentCompleted event will be fired when the navigation is completed and the browser is ready for screen shot. We will get screen shot using DrawToBitmap method as described previously which will return the bitmap of the web browser. Then the thumbnail image is generated using GetThumbnailImage method of Bitmap class passing it the required thumbnail image width and height. private void WebBrowser_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) { WebBrowser m_WebBrowser = (WebBrowser)sender; m_WebBrowser.ClientSize = new Size(this.m_BrowserWidth, this.m_BrowserHeight); m_WebBrowser.ScrollBarsEnabled = false; m_Bitmap = new Bitmap(m_WebBrowser.Bounds.Width, m_WebBrowser.Bounds.Height); m_WebBrowser.BringToFront(); m_WebBrowser.DrawToBitmap(m_Bitmap, m_WebBrowser.Bounds); m_Bitmap = (Bitmap)m_Bitmap.GetThumbnailImage(m_ThumbnailWidth, m_ThumbnailHeight, null, IntPtr.Zero); } One more example here : http://www.codeproject.com/KB/aspnet/Website_URL_Screenshot.aspx

• php image upload library

  - by Tchalvak

  I'm looking to NOT reinvent the wheel with an image upload system in php. Is there a good standalone library that allows for: Creating the system for uploading, renaming, and perhaps resizing images. Creating the front-end, html and/or javascript for the form upload parts of image upload. I've found a lot of image gallery systems, but no promising standalone system & ui libraries, ready for insertion into custom php.

• Inserting an Image into a PDF

  - by Cerin

  Are there Linux/Ubuntu programs capable of inserting a partially transparent image into a PDF? I'm trying to "sign" a PDF document by inserting an image of my signature, but even though every OSX and Windows PDF editor seems to support this, I haven't found any Linux PDF editors that do. I've tried PDFChain, PDF Editor, Flpsed PDF Annotator, Openoffice, Scribus, Krita, and PDFSam, and none support this. Although not technically a Linux program, I tried the site pdfescape.com, but it corrupts the images it inserts, rendering it useless for this task. Note, I'm talking about keeping the PDF in PDF format, so rasterizing it to a TIF/PNG/BMP, editing it in Gimp, and then dumping it back into a PDF isn't a solution. EDIT: I might have been premature in my criticism of pdfescape.com and PDF Editor. I was viewing the resulting PDF in Evince, which was showing a mangled image, but when I opened the PDF in PDF Editor, the image rendered correctly. I've since sent the PDF to someone on Windows who confirmed the image showed correctly. It looks like the problem might be inaccurate rendering with Evince.

• GZip compression with WCF hosted on IIS7

  - by joniba

  So I'm going to add my query to the small ocean of questions on the subject. I'm trying to enable GZip compression on large soap responses from a WCF service. So far, I've followed instructions here and in a variety of other places to enable dynamic compression on IIS. Here's my dynamicTypes section from the applicationHost.config: <dynamicTypes> <add mimeType="text/*" enabled="true" /> <add mimeType="message/*" enabled="true" /> <add mimeType="application/x-javascript" enabled="true" /> <add mimeType="application/atom+xml" enabled="true" /> <add mimeType="application/xaml+xml" enabled="true" /> <add mimeType="application/xop+xml" enabled="true" /> <add mimeType="application/soap+xml" enabled="true" /> <add mimeType="*/*" enabled="false" /> </dynamicTypes> And also: <urlCompression doDynamicCompression="true" dynamicCompressionBeforeCache="true" /> Though I'm not so clear on why that's needed. Threw some extra mime-types in there just in case. I've implemented IClientMessageInspector to add Accept-Encoding: gzip, deflate to my client's HttpRequests. Here's an example of a request-header taken from fiddler: POST http://[omitted]/TestMtomService/TextService.svc HTTP/1.1 Content-Type: application/soap+xml; charset=utf-8 Accept-Encoding: gzip, deflate Host: [omitted] Content-Length: 542 Expect: 100-continue Now, this doesn't work. There's simply no compression happening, no matter what the size of the message (tried up to 1.5Mb). I've looked at this post, but have not run into an exception as he describes, so I haven't tried the CodeProject implementation that he proposes. Also I've seen a lot of other implementations that are supposed to get this to work, but cannot make sense of them (e.g., msdn's GZip encoder). Why would I need to implement the encoder, or the code-project solution? Shouldn't IIS take care of the compression? So what else do I need to do to get this to work? Joni
