  • Prepare your site images for google image search indexing

    - by Vittorio Vittori
    Hi, I'm trying to understand how can I do to let my site be reachable from google image search spiders. I like how last.fm solution, and I thought to use a technique like his staff do to let google find artists images on their pages. When I'm looking for an artist and I search it on google image search, as often as not I find an image from last.fm artists page, I make an example: If I search the band Pure Reason Revolution It brings me here, the artist's image page http://www.last.fm/music/Pure+Reason+Revolution/+images/4284073 Now if I take a look to the image file, i can see it's named: http://userserve-ak.last.fm/serve/500/4284073/Pure+Reason+Revolution+4.jpg so if I try to undertand how the service works I can try to say: http://userserve-ak.last.fm/serve/ the server who serve the images 500/ the selected size for the image 4284073/ the image id for database Pure+Reason+Revolution+4.jpg the image name I thought it's difficult to think the real filename for the image is Pure+Reason+Revolution+4.jpg for image overwrite problems when an user upload it, in fact if I digit: http://userserve-ak.last.fm/serve/500/4284073.jpg I probably find the real image location and filename With this tecnique the image is highly reachable from search engines and easily archived. My question is, does exist some guide or tutorial to approach on this kind of tecniques, or something similar?

  • image transistion

    - by Jeff Main
    Hi all. I've gotten stuck again. I've got an image (album cover) that I'll be changing in code behind, and wish to basicaly do the following. When a new album cover image is determine and aquired, I want the current image in the image control to fade out, get updated with the new cover, and then fade back in. I'm not seeing very many good examples on how to accomplish this in code behind. The following was my latest failed attempt... if (currentTrack != previousTrack) { BitmapImage image = new BitmapImage(); image.BeginInit(); image.CacheOption = BitmapCacheOption.OnLoad; image.CreateOptions = BitmapCreateOptions.IgnoreImageCache; image.UriSource = new Uri(Address, UriKind.Absolute); image.EndInit(); Storyboard MyStoryboard = new Storyboard(); DoubleAnimation FadeOut = new DoubleAnimation(); FadeOut.From = 1.0; FadeOut.To = 0.0; FadeOut.Duration = new Duration(TimeSpan.FromSeconds(.5)); MyStoryboard.Children.Add(FadeOut); Storyboard.SetTargetName(FadeOut, CoverArt.Name); Storyboard.SetTargetProperty(FadeOut, new PropertyPath(Rectangle.OpacityProperty)); CoverArt.Source = image; DoubleAnimation Fadein = new DoubleAnimation(); Fadein.From = 0.0; Fadein.To = 1.0; Fadein.Duration = new Duration(TimeSpan.FromSeconds(.5)); MyStoryboard.Children.Add(Fadein); Storyboard.SetTargetName(Fadein, CoverArt.Name); Storyboard.SetTargetProperty(Fadein, new PropertyPath(Rectangle.OpacityProperty)); MyStoryboard.Begin(this); } I'd prefer to do this in code behind simply because that is where I'm aquiring the image. Otherwise, I'm not sure how I'd trigger it. An example would be greatly appriciated. Thanks.

  • problem in loading images from web

    - by Lynnooi
    hi, I am new in android and had developed an app which get images from the website and display it. I got it working in emulator but not in real phones. In some device, it will crash or take very long loading period. Can anyone please help me or guide me in improving it as i'm not sure whether the way i loads the images is correct or not. Here are the code i use to get the images from the web and display accordingly. if (xmlURL.length() != 0) { try { URL url = new URL(xmlURL); SAXParserFactory spf = SAXParserFactory.newInstance(); SAXParser sp = spf.newSAXParser(); /* Get the XMLReader of the SAXParser we created. */ XMLReader xr = sp.getXMLReader(); /* * Create a new ContentHandler and apply it to the * XML-Reader */ xr.setContentHandler(myExampleHandler); /* Parse the xml-data from our URL. */ xr.parse(new InputSource(url.openStream())); /* Parsing has finished. */ /* * Our ExampleHandler now provides the parsed data to * us. */ ParsedExampleDataSet parsedExampleDataSet = myExampleHandler.getParsedData(); } catch (Exception e) { } } if (s.equalsIgnoreCase("wallpapers")) { Context context = helloAndroid.this.getBaseContext(); for (int j = 0; j <= myExampleHandler.filenames.size() - 1; j++) { if (myExampleHandler.filenames.elementAt(j).toString() != null) { helloAndroid.this.ed = myExampleHandler.thumbs.elementAt(j) .toString(); if (helloAndroid.this.ed.length() != 0) { Drawable image = ImageOperations(context, helloAndroid.this.ed, "image.jpg"); file_info = myExampleHandler.filenames .elementAt(j).toString(); author = "\nby " + myExampleHandler.authors.elementAt(j) .toString(); switch (j + 1) { case 1: ImageView imgView1 = new ImageView(context); imgView1 = (ImageView) findViewById(R.id.image1); if (image.getIntrinsicHeight() > 0) { imgView1.setImageDrawable(image); } else imgView1 .setImageResource(R.drawable.empty_wallpaper); tv = (TextView) findViewById(R.id.filename1); tv.setText(file_info); tv = (TextView) findViewById(R.id.author1); tv.setText(author); imgView1 .setOnClickListener(new View.OnClickListener() { public void onClick(View view) { // Perform action on click Intent myIntent1 = new Intent( helloAndroid.this, galleryFile.class); Bundle b = new Bundle(); b.putString("fileID",myExampleHandler.fileid.elementAt(0).toString()); b.putString("page", "1"); b.putString("family", s); b.putString("fi",myExampleHandler.folder_id.elementAt(folder).toString()); b.putString("kw", keyword); myIntent1.putExtras(b); startActivityForResult( myIntent1, 0); } }); break; case 2: ImageView imgView2 = new ImageView(context); imgView2 = (ImageView) findViewById(R.id.image2); imgView2.setImageDrawable(image); tv = (TextView) findViewById(R.id.filename2); tv.setText(file_info); tv = (TextView) findViewById(R.id.author2); tv.setText(author); imgView2 .setOnClickListener(new View.OnClickListener() { public void onClick(View view) { // Perform action on click Intent myIntent1 = new Intent( helloAndroid.this, galleryFile.class); Bundle b = new Bundle(); b.putString("fileID",myExampleHandler.fileid.elementAt(1).toString()); b.putString("page", "1"); b.putString("family", s); b.putString("fi",myExampleHandler.folder_id.elementAt(folder).toString()); b.putString("kw", keyword); myIntent1.putExtras(b); startActivityForResult( myIntent1, 0); } }); break; case 3: //same code break; } } } } } private Drawable ImageOperations(Context ctx, String url, String saveFilename) { try { InputStream is = (InputStream) this.fetch(url); Drawable d = Drawable.createFromStream(is, "src"); return d; } catch (MalformedURLException e) { e.printStackTrace(); return null; } catch (IOException e) { e.printStackTrace(); return null; } } public Object fetch(String address) throws MalformedURLException, IOException { URL url = new URL(address); Object content = url.getContent(); return content; }

  • Load thumbnail image into PictureBox from directory

    - by zaidwaqi
    Hi, I use the following code to get thumbnail of image in Resources, and display on Picturebox. Image tmp = (System.Drawing.Image)myManager.GetObject(tempImage); cfgPassPicture[m].Image = tmp.GetThumbnailImage(40, 40, new System.Drawing.Image.GetThumbnailImageAbort(ThumbnailCallback), System.IntPtr.Zero); How do I do this for images in directory (instead of resources), given only the URL? I can load image into PictureBox via ImageLocation property, but not sure how to use Image property of PictureBox for this. Thanks

  • Resize image on upload php

    - by blasteralfred
    Hi, I have a php script for image upload as below <?php $LibID = $_POST[name]; define ("MAX_SIZE","10000"); function getExtension($str) { $i = strrpos($str,"."); if (!$i) { return ""; } $l = strlen($str) - $i; $ext = substr($str,$i+1,$l); return $ext; } $errors=0; $image=$_FILES['image']['name']; if ($image) { $filename = stripslashes($_FILES['image']['name']); $extension = getExtension($filename); $extension = strtolower($extension); if (($extension != "jpg") && ($extension != "jpeg")) { echo '<h1>Unknown extension!</h1>'; $errors=1; exit(); } else { $size=filesize($_FILES['image']['tmp_name']); if ($size > MAX_SIZE*1024) { echo '<h1>You have exceeded the size limit!</h1>'; $errors=1; exit(); } $image_name=$LibID.'.'.$extension; $newname="uimages/".$image_name; $copied = copy($_FILES['image']['tmp_name'], $newname); if (!$copied) { echo '<h1>image upload unsuccessfull!</h1>'; $errors=1; exit(); }}} ?> which uploads the image file to a folder "uimages" in the root. I have made changes in the html file for the compact display of the image by defining "max-height" and "max-width". But i want to resize the image file on upload. The image file may have a maximum width of 100px and maximum height of 150px. The image proportions must be constrained. That is, the image may be smaller than the above dimensions, but, it should not exceed the limit. How can I make this possible?? Thanks in advance :) blasteralfred..

  • Will the values of label and its correspondences change if Image is rotated?

    - by Vinayak Agarwal
    Hi all I have an image in which a text like "VINAYAK 123" is written. The text in the image is at a certain angle, say 30degrees. Now when I extract the labels of the connected components, I get V-1, I-2, N-3, A-4,Y-5,A-6,K-7, 1-8,2-9,3-10( Format: Character- Label No.). Now I rotate the image 30 degrees in the clockwise direction to make the text in the image horizontal. My question is that now if I extract the labels of the connected components, will the character and the label no. correspondence still remain the same? Thanks in advance!

  • How do I remove the white border for a gnome image

    - by gnome
    When Gnome renders an image for preview (by replacing the icon with a small version of the image itself), such as when the image is on the desktop, it adds a white border to the preview. How do I remove that white border around the image so it just shows the picture without adding a border?

  • getting Cannot identify image file when trying to create thumbnail in django

    - by Mo J. Mughrabi
    Am trying to create a thumbnail in django, am trying to build a custom class specifically to be used for generating thumbnails. As following from StringIO import StringIO from PIL import Image class Thumbnail(object): source = '' size = (50, 50) output = '' def __init__(self): pass @staticmethod def load(src): self = Thumbnail() self.source = src return self def generate(self, size=(50, 50)): if not isinstance(size, tuple): raise Exception('Thumbnail class: The size parameter must be an instance of a tuple.') self.size = size # resize properties box = self.size factor = 1 fit = True image = Image.open(self.source) # Convert to RGB if necessary if image.mode not in ('L', 'RGB'): image = image.convert('RGB') while image.size[0]/factor > 2*box[0] and image.size[1]*2/factor > 2*box[1]: factor *=2 if factor > 1: image.thumbnail((image.size[0]/factor, image.size[1]/factor), Image.NEAREST) #calculate the cropping box and get the cropped part if fit: x1 = y1 = 0 x2, y2 = image.size wRatio = 1.0 * x2/box[0] hRatio = 1.0 * y2/box[1] if hRatio > wRatio: y1 = int(y2/2-box[1]*wRatio/2) y2 = int(y2/2+box[1]*wRatio/2) else: x1 = int(x2/2-box[0]*hRatio/2) x2 = int(x2/2+box[0]*hRatio/2) image = image.crop((x1,y1,x2,y2)) #Resize the image with best quality algorithm ANTI-ALIAS image.thumbnail(box, Image.ANTIALIAS) # save image to memory temp_handle = StringIO() image.save(temp_handle, 'png') temp_handle.seek(0) self.output = temp_handle return self def get_output(self): return self.output.read() the purpose of the class is so i can use it inside different locations to generate thumbnails on the fly. The class works perfectly, I've tested it directly under a view.. I've implemented the thumbnail class inside the save method of the forms to resize the original images on saving. in my design, I have two fields for thumbnails. I was able to generate one thumbnail, if I try to generate two it crashes and I've been stuck for hours not sure whats the problem. Here is my model class Image(models.Model): article = models.ForeignKey(Article) title = models.CharField(max_length=100, null=True, blank=True) src = models.ImageField(upload_to='publication/image/') r128 = models.ImageField(upload_to='publication/image/128/', blank=True, null=True) r200 = models.ImageField(upload_to='publication/image/200/', blank=True, null=True) uploaded_at = models.DateTimeField(auto_now=True) Here is my forms class ImageForm(models.ModelForm): """ """ class Meta: model = Image fields = ('src',) def save(self, commit=True): instance = super(ImageForm, self).save(commit=True) file = Thumbnail.load(instance.src) instance.r128 = SimpleUploadedFile( instance.src.name, file.generate((128, 128)).get_output(), content_type='image/png' ) instance.r200 = SimpleUploadedFile( instance.src.name, file.generate((200, 200)).get_output(), content_type='image/png' ) if commit: instance.save() return instance the strange part is, when i remove the line which contains instance.r200 in the form save. It works fine, and it does the thumbnail and stores it successfully. Once I add the second thumbnail it fails.. Any ideas what am doing wrong here? Thanks Update: I tried earlier doing the following but I still got the same error class ImageForm(models.ModelForm): """ """ class Meta: model = Image fields = ('src',) def save(self, commit=True): instance = super(ImageForm, self).save(commit=True) instance.r128 = SimpleUploadedFile( instance.src.name, Thumbnail.load(instance.src).generate((128, 128)).get_output(), content_type='image/png' ) instance.r200 = SimpleUploadedFile( instance.src.name, Thumbnail.load(instance.src).generate((200, 200)).get_output(), content_type='image/png' ) if commit: instance.save() return instance

Or an alternative application convert it to .ISO or something equivalent. I'm looking for reassurance I won't be wasting several (more expensive than normal DVDs) dual layer DVDs to get this done right. As the .DMG file is 7gig.

  • Make a Drive Image Using an Ubuntu Live CD

    - by Trevor Bekolay
    Cloning a hard drive is useful, but what if you have to make several copies, or you just want to make a complete backup of a hard drive? Drive images let you put everything, and we mean everything, from your hard drive in one big file. With an Ubuntu Live CD, this is a simple process – the versatile tool dd can do this for us right out of the box. We’ve used dd to clone a hard drive before. Making a drive image is very similar, except instead of copying data from one hard drive to another, we copy from a hard drive to a file. Drive images are more flexible, as you can do what you please with the data once you’ve pulled it off the source drive. Your drive image is going to be a big file, depending on the size of your source drive – dd will copy every bit of it, even if there’s only one tiny file stored on the whole hard drive. So, to start, make sure you have a device connected to your computer that will be large enough to hold the drive image. Some ideas for places to store the drive image, and how to connect to them in an Ubuntu Live CD, can be found at this previous Live CD article. In this article, we’re going to make an image of a 1GB drive, and store it on another hard drive in the same PC. Note: always be cautious when using dd, as it’s very easy to completely wipe out a drive, as we will show later in this article. Creating a Drive Image Boot up into the Ubuntu Live CD environment. Since we’re going to store the drive image on a local hard drive, we first have to mount it. Click on Places and then the location that you want to store the image on – in our case, a 136GB internal drive. Open a terminal window (Applications > Accessories > Terminal) and navigate to the newly mounted drive. All mounted drives should be in /media, so we’ll use the command cd /media and then type the first few letters of our difficult-to-type drive, press tab to auto-complete the name, and switch to that directory. If you wish to place the drive image in a specific folder, then navigate to it now. We’ll just place our drive image in the root of our mounted drive. The next step is to determine the identifier for the drive you want to make an image of. In the terminal window, type in the command sudo fdisk -l Our 1GB drive is /dev/sda, so we make a note of that. Now we’ll use dd to make the image. The invocation is sudo dd if=/dev/sda of=./OldHD.img This means that we want to copy from the input file (“if”) /dev/sda (our source drive) to the output file (“of”) OldHD.img, which is located in the current working directory (that’s the “.” portion of the “of” string). It takes some time, but our image has been created…Let’s test to make sure it works. Drive Image Testing: Wiping the Drive Another interesting thing that dd can do is totally wipe out the data on a drive (a process we’ve covered before). The command for that is sudo dd if=/dev/urandom of=/dev/sda This takes some random data as input, and outputs it to our drive, /dev/sda. If we examine the drive now using sudo fdisk –l, we can see that the drive is, indeed, wiped. Drive Image Testing: Restoring the Drive Image We can restore our drive image with a call to dd that’s very similar to how we created the image. The only difference is that the image is going to be out input file, and the drive now our output file. The exact invocation is sudo dd if=./OldHD.img of=/dev/sda It takes a while, but when it’s finished, we can confirm with sudo fdisk –l that our drive is back to the way it used to be! Conclusion There are a lots of reasons to create a drive image, with backup being the most obvious. Fortunately, with dd creating a drive image only takes one line in a terminal window – if you’ve got an Ubuntu Live CD handy!

  • Lazy-loading with Spring HibernateDaoSupport ?

    - by umanga
    Greetings I am developing a non-webapplication using Spring+Hibernate. My question is how the HibernateDaoSupport handles lazy-loading , because after a call do DAO , the Session is closed. Take a look at following psuedo-code: DAO is like: CommonDao extends HibernateDaoSupport{ Family getFamilyById(String id); SubFamily getSubFamily(String familyid,String subfamilyid); } Domain model is like: Family{ private List<SubFamily> subfamiles; public List<SubFamily> getSubFamiles(); } SubFamily{ private Family family; public Family getFamily(); } In the application I get DAO from app-context and want to following operations.Is this possible to do with lazy-loading because AFAIK after every method (getFamilyById() , getSubFamily() ) the session is closed. CommonDAO dao=//get bean from application context; Family famA=dao.getFamilyById(familyid); // //Do some stuff List<SubFamily> childrenA=fam.getSubFamiles(); SubFamily asubfamily=dao.getSubFamily(id,subfamilyid); // //Do some other stuff Family famB=asubfamily.getFamily();

  • Drupal Background Image as Block or Node

    - by Marcy Sutton
    Hi There. I am having trouble wrapping my head around how to make editable background images in my custom Drupal 6 theme. My client wants to have a different background image for each main section (which use multiple content types: page, blog, image gallery)... I am wondering, is there a way to make a custom content type into a dynamic background image block? I am using the Image, Image Cache, Views, CCK, Image Assist, Panels, Filefield, and Imagefield modules. What I'd like to do is add a background image field to various content types that allows a user to reference an image from the content library or upload a new image (similar to ImageAssist), and have it apply to a region in my template. Any suggestions on the best approach for this? Thank you!

  • Powerpoint template image placeholders can't send to back

    - by Marcus
    We want to be able to set up a PowerPoint 2007 template with a picture frame image. We then want to insert an image in normal view which would appear behind the picture frame image that was put in the template (so it looks logically like a picture in a picture frame). Problem is, when we insert the image in normal view it always appears on top of the picture frame image. It appears that you can't send to back when the other elements are included in a template. Any ideas?

I've used the following way : public string ImageSource { get; set; } ImageSource = Base64StringToImage("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").Source.ToString(); but nothing happen. How can I fix it ? BTW, I'm dead sure that the base64 string is correct

  • Resizing image algorithm in python

    - by hippocampus
    So, I'm learning my self python by this tutorial and I'm stuck with exercise number 13 which says: Write a function to uniformly shrink or enlarge an image. Your function should take an image along with a scaling factor. To shrink the image the scale factor should be between 0 and 1 to enlarge the image the scaling factor should be greater than 1. This is not meant as a question about PIL, but to ask which algorithm to use so I can code it myself. I've found some similar questions like this, but I dunno how to translate this into python. Any help would be appreciated. I've come to this: import image win = image.ImageWin() img = image.Image("cy.png") factor = 2 W = img.getWidth() H = img.getHeight() newW = int(W*factor) newH = int(H*factor) newImage = image.EmptyImage(newW, newH) for col in range(newW): for row in range(newH): p = img.getPixel(col,row) newImage.setPixel(col*factor,row*factor,p) newImage.draw(win) win.exitonclick() I should do this in a function, but this doesn't matter right now. Arguments for function would be (image, factor). You can try it on OP tutorial in ActiveCode. It makes a stretched image with empty columns :.

  • Wait until image loads before performing function

    - by Steven
    I'm trying to create a simple portfolio page. I have a list of thumbs and an image. When you click on a thumb, the image will change. When a thumbnail is clicked, I'd like to have the image fade out, wait until the image is loaded, then fade back in. The problem I have right now is that some of the images are pretty big, so it fades out, then fades back in immediately, sometimes while the image is still loading. I'd like to avoid using setTimeout, since sometimes an image will load faster or slower than the time I set. Here's my code: $(function() { $('img#image').attr("src", $('ul#thumbs li:first img').attr("src")); $('ul#thumbs li img').click(function() { $('img#image').fadeOut(700); var src = $(this).attr("src"); $('img#image').attr("src", src); $('img#image').fadeIn(700); }); }); <img id="image" src="" alt="" /> <ul id="thumbs"> <li><img src="/images/thumb1.png" /></li> <li><img src="/images/thumb2.png" /></li> <li><img src="/images/thumb3.png" /></li> </ul>

  • Image not loading from cache after it's loaded in an iframe

    - by Amir
    I'm loading an image in an iframe and then (once the iframe is loaded) loading the image on the page. But most browsers seem to be loading the image twice. Why isn't the img tag being loading from the cache? Something like this: var loader = $('<iframe />').appendTo('body')[0]; loader.onload = function() { $('body').append('<img src="' + imgsrc + '" />'); }; loader.src = imgsrc; http://jsfiddle.net/amirshim/na3UA/ I'm using fiddler2 to see the network traffic. In case you want to know why I want to do this, check out this question
