  • Image scaling in C

    - by Ganesh
    Hi, I am designing a jpeg to bmp decoder which scales the image. I have been supplied with the source code for the decoder so my actual work is to design a scaler . I do not know where to begin. I have scouted the internet for the various scaling algorithms but am not sure where to introduce the scaling. So should I do the the scaling after the image is converted into bmp or should I do this during the decoding at the MCU level. am confused :( If you guys have some information to help me out, its appreciated. any material to read, source code to analyse etc....

  • How to display image in grails GSP?

    - by Walter
    I'm still learning Grails and seem to have hit a stumbling block. Here are the 2 domain classes: class Photo { byte[] file static belongsTo = Profile } class Profile { String fullName Set photos static hasMany = [photos:Photo] } The relevant controller snippet: class PhotoController { ..... def viewImage = { def photo = Photo.get( params.id ) byte[] image = photo.file response.outputStream << image } ...... } Finally the GSP snippet: <img class="Photo" src="${createLink(controller:'photo', action:'viewImage', id:'profileInstance.photos.get(1).id')}" /> Now how do I access the photo so that it will be shown on the GSP? I'm pretty sure that profileInstance.photos.get(1).id is not correct. Thanks!!

  • problem with image urls in htmlhelp created by docbook xsl

    - by newenglander
    I have a Docbook XML document that has some images with special characters in their names (German umlauts). I'm using Saxon 6.5.5 and the Docbook xslt Stylesheets to create HTMLHelp files based on that document. Unfortunately the filenames are then url-encoded (% and hexadecimal code), which internet explorer can't deal with (with firefox it works). I looked for a parameter which could change this feature, but couldn't find any. I also tried to save my image files using the encoded names, but this didn't work either. Does anyone know a good way around this, or will I have to simply forbid special characters in my image names?

  • Display Image from Byte Array in WPF - Memory Issues

    - by ChrisFletcher
    Hi, I've developed an application to capture and save images to a database, but I'm having an issue with memory usage. On my domain object I have 3 properties: Image - Byte array, contents are a jpg RealImageThumb - The byte array converted to a BitmapImage and shrunk, displayed to the user in a gridview with other thumbnails RealImage - Has no setter, the byte array converted to a bitmap source, this is shown in a tooltip when the user hovers over it. The issue I have is that if a user hovers over each image in turn the memory usage spirals. I realise that as a user hovers over bitmap sources are generated and the memory isn't freed up, I've tried giving RealImage a backing property and assigning this to null after but again the memory isn't freed up (waiting for the garbage colelctor?.

  • image analysis question for matlab

    - by raekwon
    Hi, I asked a similar question but wasn't quite clear before. I am trying to put a blue or an orange or some other colored circle (more like a donut) around a feature in an image so that I can track it. It should be more like a donut so that I can still view the image... Anyway, I have a multidimensional array and then extract 2D submatrices out of it and plot each one using imagesc(subarray). For all the subarrays there are multiple features that I've located and want to track. Is it possible in Matlab to put a donut/circle around them to do that? How would you do that?

  • CSS: background image does not fill when scrolling

    - by rekindleMyLoveOf
    Hi, working on a very small site which loads in one go, so there is a div which holds all the background images, and on top of that (i.e. higher z-index) there is a content div which holds everything. I can switch backgrounds easily based on what content is selected. Unfortunately, I noticed if you launch in a small window so that scrollbars appear, if you scroll there is no background image in the 'revealed' portions of the page. :-( Page structure: <body> <div id="bg"> <div class="bgone"></div> <div class="bgtwo"></div> </div> <div id="container"> <!-- content panels here --> </div> </body> css: #bg { margin: 0px; position: absolute; top: 0px; left: 0px; width:100%; height: 1024px; z-index:1; } .bgone { margin: 0px; position: absolute; width:100%; height: 1024px; background-image:url(../images/one.jpg); background-position:top; background-repeat:repeat-x; z-index:2; } .bgtwo { margin: 0px; position: absolute; width:100%; height: 1024px; background-image:url(../images/two.jpg); background-position:top; background-repeat:repeat-x; z-index:3; } #container { position:relative; width:900px; padding:0px; margin:0px auto; height:600px; z-index:10; }

  • User avatar cropping/resizing with paperclip and jquery in rails

    - by Micke
    Hello fellow stackoverflow users. I am building my first Ruby on Rails app which is going to be my own little community. I have made the User model with several fields and information. But now i am thinking of adding avatar support for the users. And i've been researching and found that my best option would be using Paperclip. But then i've encountered a little dilemma. I want my users to be able to resie/crop their avatar image after they have chosen a image. I have googled alot and since i am using jQuery i found that imgAreaSelect would be best in my opinion. And i think MiniMagick looks best. So to my question. How can i best intergrate Paperclip and imgAreaSelect? I am new to Ruby and Rails so i don't know how i can resize the image. Do you folks know how to intergrate the to or maybe some other options that fits my needs best? I also need to apologize for my bad/misspelled english since i am not english :) Thanking you in advance. Yours sincerely, Micke.

  • How2 display Image from DB in datagrid?

    - by Saverio Tedeschi
    Hope it's not yet been answered, but I've googled for quite a long time, and I've not been able to get it working. In brief, I've a SL4 page with a DataGrid filled accordingly to parameters passed from the previous page, so I fill the context in code, with a "RIA" query (w/parameters as well). So far, so good. I get the XAML declared columns as expected but the Photo templated column, which holds just an image control. I think I can use the LoadingRow event, but can some1 give me some code on how to get my goal (image is in in the context from DB)? Thanks in advance

  • Chnaging Displayed Image on a Webpage Using Javascript

    - by Gavin
    Hi all, I'm having some trouble changing an image being displayed on a page by way of a dropdown menu selection. This works fine.. getting the dropdown menu to give me an alert when I make a selection. Even though the menu is embedded within a division, paragraph, and label tag, it still works. "availableImages" is the name of my menu. function imageSelect() { var index = document.getElementById("myForm").availableImages.selectedIndex; var value = document.getElementById("myForm").availableImages.options[index].value; alert("test " + value); // alert box pops up upon list item selection } However, within the same division, I am having an issue with changing the source of my image tag... Any ideas? I will provide more code if it will be helpful. Thanks! Gavin

  • HTML/JavaScript: mouseover effect for image maps?

    - by MVCDummy09
    I'm trying to help out a nonprofit by doing their website. They want (ugh) their logo to serve as an HTML image map. In other words, when you click on different parts of the logo, you're directed to different web pages. They also, however, want mouseover effects: when you mouseover a particular portion of the image map, that piece of the graphic should be highlighted. If the logo was simple, I would slice it up into rectangles and attach mouseover and click events to the appropriate rectangles. With the complexity of their logo, this is not possible, however. Has anyone done anything like this without Flash? I'm not a Flash developer but this is looking like a very difficult task in just HTML/JavaScript. Any ideas? Thanks!

  • How to create an Universal Binary for iTunes Connect Distribution?

    - by balexandre
    I created an app that was rejected because Apple say that my App was not showing the correct iPad window and it was showing the same iPhone screen but top left aligned. Running on simulator, I get my App to show exactly what it should, a big iPad View. my app as Apple referees that is showing on device: my app running the simulator (50% zoom only): my code in the Application Delegate is the one I published before - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // The default have the line below, let us comment it //MainViewController *aController = [[MainViewController alloc] initWithNibName:@"MainView" bundle:nil]; // Our main controller MainViewController *aController = nil; // Is this OS 3.2.0+ ? #if __IPHONE_OS_VERSION_MAX_ALLOWED >= 30200 if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) // It's an iPad, let's set the MainView to our MainView-iPad aController = [[MainViewController alloc] initWithNibName:@"MainView-iPad" bundle:nil]; else // This is a 3.2.0+ but not an iPad (for future, when iPhone/iPod Touch runs with same OS than iPad) aController = [[MainViewController alloc] initWithNibName:@"MainView" bundle:nil]; #else // It's an iPhone/iPod Touch (OS < 3.2.0) aController = [[MainViewController alloc] initWithNibName:@"MainView" bundle:nil]; #endif // Let's continue our default code self.mainViewController = aController; [aController release]; mainViewController.view.frame = [UIScreen mainScreen].applicationFrame; [window addSubview:[mainViewController view]]; [window makeKeyAndVisible]; return YES; } on my target info I have iPhone/iPad My question is, how should I build the app? Use Base SDK iPhone Simulator 3.1.3 iPhone Simulator 3.2 my Active Configuration is Distribution and Active Architecture is arm6 Can anyone that already published app into iTunes Connect explain me the settings? P.S. I followed the Developer Guideline on Building and Installing your Development Application that is found on Creating and Downloading Development Provisioning Profiles but does not say anything regarding this, as I did exactly and the app was rejected.

  • href image link download on click

    - by Piero
    Hey all, I generate normal links like: <a href="/path/to/image"><img src="/path/to/image" /></a> in a web app. When I click on the link, it displays the picture in a new page. If you want to save the picture, then you need to right click on it and select "save as" I don't want this behaviour, I would like to have a download box popping out when I click on the link, is that possible just with html or javascript? How? If not I guess I would have to write a download.php scrit and call it into the href with the file name as parameter...? Greetings! :)

  • How to improve performance of map that loads new overlay images

    - by anthonysomerset
    I have inherited a website to maintain that uses a html map overlaying a real map to link specific countries to specific pages. previously it loaded the default map image, then with some javascript it would change the image src to an image with that particular country in a different colour on mouseover and reset the image source back to the original image on mouse out to make maintenance (adding new countries) easier i made the initial map a background image by utilising some CSS for the div tag, and then created new images for each country which only had that countries hightlight so that the images remain fairly small. this works great but theres one issue which is particularly noticeable on slower internet connections when you hover over a country if you dont have the image file in your browser cache or downloaded it wont load the image unless you hover over another country and then back onto the first country - i guess this is due to the image having to manually be downloaded on first hover. My question: is it possible to force the load of these extra images AFTER the page and all the other assets have finished loading so that this behaviour is all but eliminated? the html code for the MAP is as follows: <div class="gtmap"><img id="Image-Maps_6200909211657061" src="<?php echo cdnhttpsCheck();

  • Image 8-connectivity without excessive branching?

    - by shoosh
    I'm writing a low level image processing algorithm which needs to do alot of 8-connectivity checks for pixels. For every pixel I often need to check the pixels above it, below it and on its sides and diagonals. On the edges of the image there are special cases where there are only 5 or 3 neighbors instead of 8 neighbors for a pixels. The naive way to do it is for every access to check if the coordinates are in the right range and if not, return some default value. I'm looking for a way to avoid all these checks since they introduce a large overhead to the algorithm. Are there any tricks to avoid it altogether?

  • how to flip Image in wpf

    - by shashank
    Hello! I recently learned how to rotate a BitmapImage using the 'TransformedBitmap' and 'RotateTransformed' classes. Now I am able to perform clockwise rotations on my images. But how do I FLIP an image? I can't find the class(es) to perform horizontal and vertical flips of a BitmapImage. Please help me figure out how to do it. For instance, if my image was a drawing that looked like a 'd', then a vertical flip would result in something like a 'q', and a horizontal flip would result in something lika a 'b'. I hope this is clear enough. Thanks in advance! Best regards, shashank

  • Image coding library

    - by Dmitry
    Is there any good library for lossless image encoding/decoding that has compression rate more or less similar to PNG but decoding to raw RGB bitmap data would be much faster than PNG? Also alpha transparency is needed, but not essential because, alpha channel could be taken from separate image. Original problem lies in slowness of reading and decoding PNG files on iPhone using standard libraries. Obvious and the simples solution would have been storing raw RGB bitmap data, but then size of unpacked ipa is too large - 4 times larger than PNG files. So, I am trying to find some compromise solution.

  • Paint java GUI component to image file

    - by Simon
    Let's say I have JButton test = new JButton("Test Button"); and I want to draw the button into an image object and save it to a file. I tried this: BufferedImage b = new BufferedImage(500, 500, BufferedImage.TYPE_INT_ARGB); test.paint(b.createGraphics()); File output = new File("C:\\screenie.png"); try { ImageIO.write(b, "png", output); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } This code produced an empty 500x500 PNG-file. Does anyone know how I can draw the GUI component to an image file?

  • image upload problem.

    - by Bluemagica
    I wrote a function to resize and upload images...it works, but only for one image. So if I call the function three times, I end up with 3 copies of the last image..... function uploadImage($name,$width,$height,$size,$path='content/user_avatars/') { //=================================================== //Handle image upload $upload_error=0; //Picture $img = $_FILES[$name]['name']; if($img) { $file = stripslashes($_FILES[$name]['name']); $ext = strtolower(getExt($file)); if($ext!='jpg' && $ext!='jpeg' && $ext!='png' && $ext!='gif') { $error_msg = "Unknown extension"; $upload_error = 1; return array($upload_error,$error_msg); } if(filesize($_FILES[$name]['tmp_name'])>$size*1024) { $error_msg = "Max file size of ".($size*1024)."kb exceeded"; $upload_error = 2; return array($upload_error,$error_msg); } $newFile = time().'.'.$ext; resizeImg($_FILES[$name]['tmp_name'],$ext,$width,$height); $store = copy($_FILES[$name]['tmp_name'],$path.$newFile); if(!$store) { $error_msg = "Uploading failed"; $upload_error = 3; return array($upload_error,$error_msg); } else { return array($upload_error,$newFile); } } } //========================================================================================= //Helper Functions function getExt($str) { $i = strpos($str,"."); if(!$i) { return ""; } $l = strlen($str)-$i; $ext = substr($str,$i+1,$l); return $ext; } function resizeImg($file,$ext,$width,$height) { list($aw,$ah) = getimagesize($file); $scaleX = $aw/$width; $scaleY = $ah/$height; if($scaleX>$scaleY) { $nw = round($aw*(1/$scaleX)); $nh = round($ah*(1/$scaleX)); } else { $nw = round($aw*(1/$scaleY)); $nh = round($ah*(1/$scaleY)); } $new_image = imagecreatetruecolor($nw,$nh); imagefill($new_image,0,0,imagecolorallocatealpha($new_image,255,255,255,127)); if($ext=='jpg'||$ext=='jpeg') { $src_image = imagecreatefromjpeg($file); } else if($ext=='gif') { $src_image = imagecreatefromgif($file); } else if($ext=='png') { $src_image = imagecreatefrompng($file); } imagecopyresampled($new_image,$src_image,0,0,0,0,$nw,$nh,$aw,$ah); if($ext=='jpg'||$ext=='jpeg') { imagejpeg($new_image,$file,100); } else if($ext=='gif') { imagegif($new_image,$file); } else if($ext=='png') { imagepng($new_image,$file,9); } imagedestroy($src_image); imagedestroy($new_image); } I have a form with two upload fields, 'face_pic' and 'body_pic', and I want to upload these two to the server and resize them before storing. Any ideas?

  • Invoking SQL Loader with a DSN

    - by Zack
    I'm trying to load some data to an Oracle database using SQL Loader. Is it possible to invoke it with specifying the server to load the data into using a DSN instead of a TNS? Right now my command line looks like this: sqlldr uesr/password@tns_id..., I'd like to replace tns_id with a DSN that points to tns_id. Can SQL Loader figure out the TNS from the DSN by itself?
