  • Indexing community images for google image search

    - 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.

  • 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

  • How to convert or burn a .DMG image file on Windows?

    Does anyone have software they use frequently and can recommend to burn a mac created .DMG file on a windows operating system? Ideally free, or at least reasonably priced. 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!

  • 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 have below XAML code : <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" DataContext="{Binding RelativeSource={RelativeSource Self}}" WindowStartupLocation="CenterScreen" Title="Window1" Height="300" Width="300"> <Grid> <Image x:Name="TestImage" Source="{Binding Path=ImageSource}" /> </Grid> </Window> Also, there is a method that makes an Image from a Base64 string : Image Base64StringToImage(string base64ImageString) { try { byte[] b; b = Convert.FromBase64String(base64ImageString); MemoryStream ms = new System.IO.MemoryStream(b); System.Drawing.Image img = System.Drawing.Image.FromStream(ms); ////////////////////////////////////////////// //convert System.Drawing.Image to WPF image System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(img); IntPtr hBitmap = bmp.GetHbitmap(); System.Windows.Media.ImageSource imageSource = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(hBitmap, IntPtr.Zero, Int32Rect.Empty, BitmapSizeOptions.FromEmptyOptions()); Image wpfImage = new Image(); wpfImage.Source = imageSource; wpfImage.Width = wpfImage.Height = 16; ////////////////////////////////////////////// return wpfImage; } catch { Image img1 = new Image(); img1.Source = new BitmapImage(new Uri(@"/passwordManager;component/images/TreeView/empty-bookmark.png", UriKind.Relative)); img1.Width = img1.Height = 16; return img1; } } Now, I'm gonna bind TestImage to the output of Base64StringToImage method. I've used the following way : public string ImageSource { get; set; } ImageSource = Base64StringToImage("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").Source.ToString(); but nothing happen.

  • Automatic type conversion in Java?

    - by davr
    Is there a way to do automatic implicit type conversion in Java? For example, say I have two types, 'FooSet' and 'BarSet' which both are representations of a Set. It is easy to convert between the types, such that I have written two utility methods: /** Given a BarSet, returns a FooSet */ public FooSet barTOfoo(BarSet input) { /* ... */ } /** Given a FooSet, returns a BarSet */ public BarSet fooTObar(FooSet input) { /* ... */ } Now say there's a method like this that I want to call: public void doSomething(FooSet data) { /* .. */ } But all I have is a BarSet myBarSet...it means extra typing, like: doSomething(barTOfoo(myBarSet)); Is there a way to tell the compiler that certain types can automatically be cast to other types? I know this is possible in C++ with overloading, but I can't find a way in Java. I want to just be able to type: doSomething(myBarSet); And the compiler knows to automatically call barTOfoo()

  • 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 :.

  • cvs to mercurial conversion gets tags wrong

    - by Mark Borgerding
    I've tried all the recommended conversion techniques Mostly they manage to get the latest version of the files right, but every one of them trashes my history. Many (most?) of the tags from my cvs project have at least one file in error when I run "hg up $tag" My cvs repo is not all that complicated. Why can't anything convert it? I'd like to dump cvs and convert to mercurial, but not without history. To recap my frustration: I tried hg convert (tried --branchsort,--timesort, fuzz=0) I tried cvs2svn and then hg convert. tailor does not work with recent versions of mercurial fromcvs disappeared from the face of the earth hg-cvs-import has been abandoned for 4 years and doesn't work with recent versions of hg I have tried using the two most recent versions of mercurial ( 1.5 and 1.5.1 ).

  • JSP/JSF conversion to ASP.NET

    - by sharru
    I have a pretty big JSF web application. I must convert the application to ASP.NET. I already converted the Java code to C# code manually and also using JCLA (Java Language Conversion Assistant from Microsoft). What is the best way to convert the JSF part to ASP.NET? Is there any tool that can help shorten the work? For example convert JSF <t:dataList> to ASP.NET datagrid, or converting panelGroup to asp:panel, etc...

  • Using implicit conversion as a substitute for multiple inheritance in .NET

    - by Daniel Plaisted
    I have a situation where I would like to have objects of a certain type be able to be used as two different types. If one of the "base" types was an interface this wouldn't be an issue, but in my case it is preferable that they both be concrete types. I am considering adding copies of the methods and properties of one of the base types to the derived type, and adding an implicit conversion from the derived type to that base type. Then users will be able treat the derived type as the base type by using the duplicated methods directly, by assigning it to a variable of the base type, or by passing it to a method that takes the base type. It seems like this solution will fit my needs well, but am I missing anything? Is there a situation where this won't work, or where it is likely to add confusion instead of simplicity when using the API?

  • opencv image conversion from rgb to hsv

    - by kaushalyjain
    When I run this following code on a sample image ie an rgb image; and then execute it to display the converted hsv image, both appear to be different... can anyone explain why? or can you suggest a solution for this not to happen... coz its the same image afterall Mat img_hsv,img_rgb,red_blob,blue_blob; img_rgb = imread("pic.png",1); cvtColor(img_rgb,img_hsv,CV_RGB2HSV); namedWindow("win1", CV_WINDOW_AUTOSIZE); imshow("win1", img_hsv);
