  • How to export pdf page as a image using pdfsharp .net library ?

    - by vi.su.
    How to export a pdf page as an image using pdfsharp .net library, for pixel level manipulation ? for example, something like, System.Drawing.BitMap.GetPixel() I am trying to find out empty area (all white, or of any colour) inside a pdf document, to write some graphics / image. 09, June 2010: I have tried this, but it is not working. why the following code is not working as expected ? Bitmap.GetPixel always returns 0. // // PdfSharp.Pdf.PdfDocument // PdfSharp.Pdf.PdfPage // PdfSharp.Drawing.XGraphics // System.Drawing.Bitmap // string srcPDF = @"C:\hcr\test\tmp\file1.pdf"; PdfDocument pdfd = PdfReader.Open(srcPDF); XGraphics xgfx = XGraphics.FromPdfPage(pdfd.Pages[0]); Bitmap b = new Bitmap((int) pdfp.Width.Point, (int) pdfp.Height.Point, xgfx.Graphics); int rgb = b.GetPixel(0, 0).ToArgb();

  • How does Silverlight Image Clipping work?

    - by TreeUK
    I've got a very large image which I'd like to use for sprite techniques (à la css image sprites). I've got the code below: <Image x:Name="testImage" Width="24" Height="12" Source="../Resources/Images/sprites.png"> <Image.Clip> <RectangleGeometry Rect="258,10632,24,12" /> </Image.Clip> </Image> This clips the source image to 24x12 at the relative position of 258, 10632 in the source image. The problem is that I want the cropped image to show at 0,0 in the testImage whereas it shows it at 258, 10632. It's using the geometry as a cutting guide but also as a layout guide. Anyone have any idea how this should be done? if at all. Conclusion: There seems to be no good way of doing this at present, Graeme's solution seems to be the closest to achieving this with Silverlight 2.0. That said, if anyone knows of a better way of doing this, please reply with an answer.

  • UIBarButtonItem with custom image and no border

    - by mongeta
    Hello, I want to create a UIBarButtonItem with a custom image, but I don't want the border that iPhone adds, as my Image has a special border. It's the same as the back button but a forward button. This App is for an inHouse project, so I don't care if Apple reject or approves it or likes it :-) If I use the initWithCustomView:v property of the UIBarButtonItem, I can do it: UIImage *image = [UIImage imageNamed:@"right.png"]; UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; [button setBackgroundImage: [image stretchableImageWithLeftCapWidth:7.0 topCapHeight:0.0] forState:UIControlStateNormal]; [button setBackgroundImage: [[UIImage imageNamed: @"right_clicked.png"] stretchableImageWithLeftCapWidth:7.0 topCapHeight:0.0] forState:UIControlStateHighlighted]; button.frame= CGRectMake(0.0, 0.0, image.size.width, image.size.height); [button addTarget:self action:@selector(AcceptData) forControlEvents:UIControlEventTouchUpInside]; UIView *v=[[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, image.size.width, image.size.height) ]; [v addSubview:button]; UIBarButtonItem *forward = [[UIBarButtonItem alloc] initWithCustomView:v]; self.navigationItem.rightBarButtonItem= forward; [v release]; [image release]; This works, but if I have to repeat this process in 10 views, this is not DRY. I suppose I have to subclass, but what ? NSView ? UIBarButtonItem ? thanks, regards,

  • Silverlight - Image Not Loading from URI at Runtime!?

    - by Sootah
    I've added an image element to my Silverlight app, and while the image pulls right up when in design mode, it doesn't load at all when running the app. Code is: <Image Height="95" HorizontalAlignment="Left" Margin="12,541,0,0" Name="imgBannerAd" Stretch="Fill" VerticalAlignment="Top" Width="828" Source="http://myurl.com/images/theimage.png" /> What's the deal? I'd tried running the file via the local hard drive and localhost, neither has any effect.

  • Dynamically inserting an image with JavaScript does not work on images that 302 redirect

    - by Samuel Clay
    I am dynamically inserting an image into an HTML document using jQuery. Here is the code: var image_url = "http://www.kottke.org/plus/misc/images/castro-pitching.jpg"; var $image = $('<img src="'+image_url+'" width="50" height="50" />'); $('body').prepend($image); Notice that the image http://www.kottke.org/plus/misc/images/castro-pitching.jpg is actually a 302 redirect to http://kottkegae.appspot.com/images/castro-pitching.jpg. If you were to go to the original image in your browser, it works fine. If you were to load an HTML page with that image in an img tag, it would load fine. However, if you were to insert it dynamically using jQuery (or JavaScript, for that matter), the browser will not show the 302'ed image. If you show the redirected image, it would work fine. var image_url = "http://kottkegae.appspot.com/images/castro-pitching.jpg"; var $image2 = $('<img src="'+image_url+'" width="50" height="50" />'); $('body').prepend($image2); That's crazy, right? What gives and how can I force the image to load when inserted dynamically?

  • JavaScript Image zoom with CSS3 Transforms, How to calculate Origin? (with example)

    - by Sunday Ironfoot
    I'm trying to implement an image zoom effect, a bit like how the zoom works with Google Maps, but with a grid of fix position images. I've uploaded an example of what I have so far here: http://www.dominicpettifer.co.uk/Files/MosaicZoom.html (uses CSS3 transforms so only works with Firefox, Opera, Chrome or Safari) Use your mouse wheel to zoom in/out. The HTML source is basically an outer div with an inner-div, and that inner-div contains 16 images arranged using absolute position. It's going to be a Photo Mosaic basically. I've got the zoom bit working using CSS3 transforms: $(this).find('div').css('-moz-transform', 'scale(' + scale + ')'); ...however, I'm relying on the mouse X/Y position on the outer div to zoom in on where the mouse cursor is, similar to how Google Maps functions. The problem is that if you zoom right in on an image, move the cursor to the bottom/left corner and zoom again, instead of zooming to the bottom/left corner of the image, it zooms to the bottom/left of the entire mosaic. This has the effect of appearing to jump about the mosaic as you zoom in closer while moving the mouse around, even slightly. That's basically the problem, I want the zoom to work exactly like Google Maps where it zooms exactly to where your mouse cursor position is, but I can't get my head around the Maths to calculate the transform-origin: X/Y values correctly. Please help, been stuck on this for 3 days now. Here is the full code listing for the mouse wheel event: var scale = 1; $("#mosaicContainer").mousewheel(function(e, delta) { if (delta > 0) { scale += 1; } else { scale -= 1; } scale = scale < 1 ? 1 : (scale > 40 ? 40 : scale); var x = e.pageX - $(this).offset().left; var y = e.pageY - $(this).offset().top; $(this).find('div').css('-moz-transform', 'scale(' + scale + ')') .css('-moz-transform-origin', x + 'px ' + y + 'px'); return false; });

    - by Diego Correa
    Hello guys, I've made an application that makes full use of ajax, and what I need to do is: I want a button with a description + image that when clicked is disabled and instead of the original image in the button, appears the ajax loading element id inside the button. And when the ajax loading is complete, the original image of the button returns to the normal. Is there any good source on how to do something like this? What do you guys suggest?

  • How to recognise vehicle licence / number plate (ANPR) from an image?

    - by Ryan ONeill
    Hi all, I have a web site that allows users to upload images of cars and I would like to put a privacy filter in place to detect registration plates on the vehicle and blur them. The blurring is not a problem but is there a library or component (open source preferred) that will help with finding a licence within a photo? Caveats; I know nothing is perfect and image recognition of this type will provide false positive and negatives. I appreciate that we could ask the user to select the area to blur and we will do this as well, but the question is specifically about finding that data programmatically; so answers such as 'get a person to check every image' is not helpful. This software method is called 'Automatic Number Plate Recognition' in the UK but I cannot see any implementations of it as libraries. Any language is great although .Net is preferred. Thanks in advance Ryan

  • Saving and retrieving image in SQL database from C# problem

    - by Mobin
    I used this code for inserting records in a person table in my DB System.IO.MemoryStream ms = new System.IO.MemoryStream(); Image img = Image_Box.Image; img.Save(ms, System.Drawing.Imaging.ImageFormat.Bmp); this.personTableAdapter1.Insert(NIC_Box.Text.Trim(), Application_Box.Text.Trim(), Name_Box.Text.Trim(), Father_Name_Box.Text.Trim(), DOB_TimePicker.Value.Date, Address_Box.Text.Trim(), City_Box.Text.Trim(), Country_Box.Text.Trim(), ms.GetBuffer()); but when i retrieve this with this code byte[] image = (byte[])Person_On_Application.Rows[0][8]; MemoryStream Stream = new MemoryStream(); Stream.Write(image, 0, image.Length); Bitmap Display_Picture = new Bitmap(Stream); Image_Box.Image = Display_Picture; it works perfectly fine but if i update this with my own generated Query like System.IO.MemoryStream ms = new System.IO.MemoryStream(); Image img = Image_Box.Image; img.Save(ms, System.Drawing.Imaging.ImageFormat.Bmp); Query = "UPDATE Person SET Person_Image ='"+ms.GetBuffer()+"' WHERE (Person_NIC = '"+NIC_Box.Text.Trim()+"')"; the next time i use the same code for retrieving the image and displaying it as used above . Program throws an exception

  • Display new image on web page

    - by RuiT
    Hello, I'm uploading images to a folder and I want to display each new image on a web page every time it is saved in the folder. I can display the initial image, which is already in the folder, and I can also detect when a new image is saved into the folder but I don't know how to display the new images. I'm new to web development. Can somebody help me? Here's the code: public partial class _Default : System.Web.UI.Page { string DirectoryPath = "C:\\Users\\Desktop\\PhotoUpload\\Uploads\\"; protected void Page_Load(object sender, EventArgs e) { FileSystemWatcher watcher = new FileSystemWatcher(); try { watcher.Path = DirectoryPath; watcher.Created += new FileSystemEventHandler(watcher_Created); watcher.EnableRaisingEvents = true; Image image = Image.FromFile(DirectoryPath + "inicial.jpg"); MemoryStream ms = new MemoryStream(); image.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg); byte[] im = ms.ToArray(); Context.Response.ContentType = "Image/JPG"; Context.Response.BinaryWrite(im); } catch (Exception ex) { } } void watcher_Created(object sender, FileSystemEventArgs e) { Console.WriteLine("File Created: Name: " + e.Name); try { //How to display new image? } catch (Exception ex) { } } }

  • Best Free Windows Imaging Software For Servers

    - by Justin
    We are running two physical servers both Windows 2003, not virtualized. What is the best free (if any) windows software to take a full image backup of the entire drives? If possible, while the image is taking place, it should not bring the hosts to their knees with excess CPU or I/O usage. The servers have RAID mirroring, but after hearing a few horror stories about hacked systems, we need to have weekly full image backups, so we can simply revert to a pre-hacked image. Thanks.

  • CSS Background image in Redmine template arbitrarily not loading

    - by Pekka
    I`m in the process of building a template for Redmine (a project management system based on Ruby on Rails.) Ruby is running on a virtual server from a Bitnami.org installation package. The OS is Windows. The template essentially consists of a styles.css file. In that file, I have the following line: #header { padding: 0px; padding-top: 48px; background-color: #62DFFF; background-image: url(../images/bkg.jpg) background-position: center bottom; background-repeat: repeat-x; height:150px; } It's a header element with a background image. The problem: This background image arbitrarily appears and disappears when reloading. Say you reload ten times in twenty seconds; the image will appear in two instances, and be missing in the 18 others. I would have put this down to server problems, but the weird thing is that when it's missing, the request for the image doesn't appear in Firebug's net tab at all. Even if it were cached, the request should be there. Raw screenshots of the identical page on two reloads: I am 100% sure the CSS file does not change in between. I have examined both instances with Firebug and the CSS is identical. It happens in both Firefox and Chrome so it must be something basic I'm overlooking. What could be causing a browser not to load a resource at all? I have zero idea about Ruby nor Rails - getting Redmine running and customized is all I have ever had to do with this platform - so I don't really know where to look. Apache's, Mongrel's and Redmine's error logs look fine, though.

  • JavaScript + Maths: Image zoom with CSS3 Transforms, How to set Origin? (with example)

  • HTML + CSS: fixed background image and body width/min-width (including fiddle)

    - by insertusernamehere
    So, here is my problem. I'm kinda stuck at the moment. I have a huge background image and content in the middle with those attributes: content is centered with margin auto and has a fixed width the content is related to the image (like the image is continued within the content) this relation is only horizontally (vertically scrolling moves everything around) This works actually fine (I'm only talking desktop, not mobile here :) ) with a position fixed on the huge background image. The problem that occurs is the following: When I resize the window to "smaller than the content" the background image gets it width from the body instead of the viewport. So the relation between content and image gets lost. Now I have this little JavaScript which does the trick, but this is of course some overhead I want to avoid: $(window).resize(function(){ img.css('left', (body.width() - img.width()) / 2 ); }); This works with a fixed positioned image, but can get a litty jumpy while calculating. I also tried things like that: <div id="test" style=" position: absolute; z-index: 0; top: 0; left: 0; width: 100%: height: 100%; background: transparent url(content/dummy/brand_backgroud_1600_1.jpg) no-repeat fixed center top; "></div> But this gets me back to my problem described. Is there any "script-less", elegant solution for this problem? UPDATE: now with Fiddle The one I'm trying to solve: http://jsfiddle.net/insertusernamehere/wPmrm/ The one with Javascript that works: http://jsfiddle.net/insertusernamehere/j5E8z/ NOTE The image size is always fixed. The image never gets scaled by the browser. In the JavaScript example it get's blown. So don't care about the size.

  • GDI+ Rotated sub-image

    - by Andrew Robinson
    I have a rather large (30MB) image that I would like to take a small "slice" out of. The slice needs to represent a rotated portion of the original image. The following works but the corners are empty and it appears that I am taking a rectangular area of the original image, then rotating that and drawing it on an unrotated surface resulting in the missing corners. What I want is a rotated selection on the original image that is then drawn on an unrotated surface. I know I can first rotate the original image to accomplish this but this seems inefficient given its size. Any suggestions? Thanks, public Image SubImage(Image image, int x, int y, int width, int height, float angle) { var bitmap = new Bitmap(width, height); using (Graphics graphics = Graphics.FromImage(bitmap)) { graphics.TranslateTransform(bitmap.Width / 2.0f, bitmap.Height / 2.0f); graphics.RotateTransform(angle); graphics.TranslateTransform(-bitmap.Width / 2.0f, -bitmap.Height / 2.0f); graphics.DrawImage(image, new Rectangle(0, 0, width, height), x, y, width, height, GraphicsUnit.Pixel); } return bitmap; }

  • Determine image src in onload and onerror event handlers in IE

    - by Bill
    How can I determine the image src of the image that triggered the event in the onload and onerror event handlers in IE? This example code I threw together: <script language="javascript" type="text/javascript" src="jquery.js"></script> <script language="javascript" type="text/javascript"> function loadImages() { var goodImage = new Image(); var missingImage = new Image(); $(goodImage).bind('load', function(event){ $("#log").append( $(event.target).attr('src') + ' WAS FOUND <br>'); }); $(missingImage).bind('load', function(event){ $("#log").append( $(event.target).attr('src') + ' WAS FOUND <br>' ); }); $(goodImage).bind('error', function(event){ $("#log").append( $(event.target).attr('src') + ' IS MISSING <br>'); }); $(missingImage).bind('error', function(event){ $("#log").append( $(event.target).attr('src') + ' IS MISSING <br>'); }); goodImage.src = 'GOOD-IMAGE.GIF'; // this image exists missingImage.src = 'MISSING-IMAGE.GIF'; // this image doesn't exist } </script> </head> <body onload="loadImages();"> <div id="log"></div> works in FF but in IE8 it prints out undefined for the $(event.target).attr('src') part. I thought jQuery was supposed to normalize the event object for IE so that it acted like other browsers? I've tried a number of permutations but haven't been able to get anything to work in IE8. Anyway if anyone has a suggestion on how to figure out the image src in the onload and onerror event handlers that works in IE I would really appreciate it. Or even how to figure out after the images have loaded which have loaded and which haven't (but not graphically - I need to generate an array containing the filenames of the images that didn't load). Thanks!

  • Java applet loading images from external jars

    - by Mathias
    I have a jar on a server, and users should be able to develop extensions for it. Therefore the jars main class should be extended and some resources should be added to a second user created jar which will be loaded from another server or locally. Now I have problems accessing the resources (images) from the user loaded jars. Heres is the structure: My Server: game.jar containing game.class images.class ... image1.png (...) Local: user.jar containing: user.class extends game userimage.png The extension is loaded via Greasemonkey, it modifies the "archive" attribute to "/home/username/user.jar, game.jar" and the "code" attribute to "user.class". The user should be able to overwrite already defined images. If the image does not exist in game.jar, it is loaded correctly from user.jar. But the images loaded early in the game are always loaded from the game.jar, others seem to be overwritten correctly by the user. Is there a way to make sure they are always loaded in the correct order? This might be because of some caching mechanism. Because Greasemonkey removes the game from the page, changes the archive and code and reinsert it, the game is loaded without a mod for a brief second. In that time, images are loaded as expected from game jar, but those are the ones not being overwritable by the user. But how to avoid it? Another thing: If I overwrite the "run" method in user.class, the game is unable to load any image at all. Not from the user.jar and not from the game.jar. Java doesn't find the image, as the URL object "getClass().getResource(imagename)" returns with null. I tried to overwrite the image.class, but that doesn't fix the problem, unless I overwrite every class from game.class involved into calling the image.class

  • How Does Facebook Know What Image To Parse Out of An Article?

    - by Travis
    First off I want to say that I wasn't really sure where to post this but it is very much programming related. If it is in the wrong spot I apologize and please let me know where I should post it instead. When sharing an article on a friends wall, facebook will grab a thumbnail of the article. How do they always get the right thumbnail from articles? It doesn't grab the logo img element of of http://www.nytimes.com/2010/06/07/world/asia/07convoys.html?hp for example but rather grabs the correct image element that corresponds with the article. I'm looking to do something similar and was wondering of a good way to parse the html to find the image given this example. Thanks.
