  • SQL Peer-to-Peer Dynamic Structured Data Processing Collaboration

    Unstructured and XML semi-structured data is now used more than structured data. But fixed structured data still keeps businesses running day in and day out, which requires consistent predictable highly principled processing for correct results. For this reason, it would be very useful to have a general purpose SQL peer-to-peer collaboration capability that can utilize highly principled hierarchical data processing and its flexible and advanced structured processing to support dynamically structured data and its dynamic structured processing. This flexible dynamic structured processing can change the structure of the data as necessary for the required processing while preserving the relational and hierarchical data principles. This processing will perform freely across remote unrelated peer locations anytime and transparently process unpredictable and unknown structured data and data type changes automatically for immediate processing using automatic metadata maintenance.

  • How do i bind an image to a <asp:Image /> tag in Form View

    - by Ranhiru
    First i have a getProfileImage.aspx which accepts a CusID and TN as query strings and display n image. So getProfileImage.aspx?CusID=10&TN=Y will show the image fine in the browser :) But... Now i am presented with a Form View and i want to bind the src of the image to get the image from the getProfileImage.aspx page... The following code works fine :) 10 is the customer ID and the image is working fine... <asp:Image ID="Image1" runat="server" Height="151px" ImageUrl='~/getProfileImage.aspx?CusID=10&TN=N' /> But now i want to Bind the CusID value... <asp:Image ID="Image1" runat="server" Height="151px" ImageUrl='~/getProfileImage.aspx?CusID=<%# Bind("CusID") %>&TN=N' /> This simply does not work :( The getProfileImage.aspx is called with CusID=<%... where the way i see it the <%# Bind("CusID") % is not parsed by ASP which would have returned 10... <%# Bind("CusID") %> The above tag alone will work... but inserting it to the middle of the tag seems to break it... Any suggestions ? Thanx a lot in advance :)

  • Generate image with Drupal imagecache before using imagecache_create_path & getimagesize

    - by ozke
    Hi guys, I'm using imagecache_create_path() and getimagesize() to get the path of a imagecache-generated image and its dimensions. However, if it's the first time we access the page that image doesn't exist yet and imagecache_create_path doesn't generate it either. Here's the code: // we get the image path from a preset (always return the path even if the file doesn't exist) $small_image_path = imagecache_create_path('gallery_image_small', $image["filepath"]); // I get the image dimensions (only if the file exists already) $data_small = list($width, $height, $type, $image_attributes) = @getimagesize($small_image_path); Is there any API method to get the path AND generate the file? In other words, can I generate the image (using a preset) from PHP without showing it in the browser? Thank you in advance

  • Creating new image in a loop using OpenCV

    - by user565415
    I am programing some image conversion code with OpenCV and I don't know how can I create image memory buffer to load image on every iteration. I have number of iteration (maxImNumber) and I have an input image. In every loop program must create image that is resized and modified input image. Here is some basic code (concept). for (int imageIndex = 0; imageIndex < maxImNumber; imageIndex++){ cvCopy(inputImage, images[imageIndex], 0); cvReleaseImage(&inputImage); images[imageIndex+1] = cvCreateImage(cvSize((image[imageIndex]->width)/2, image[imageIndex]->height), IPL_DEPTH_8U, 1); for (i=1; i < image[imageIndex]->height; i++) { index = 0; // for(j=0; j < image[imageIndex]->width ; j=j+2){ // doing some basic matematical operation on image content and store it to new image images[imageIndex+1][i][index] = (image[imageIndex][i][j] + image[imageIndex][i][j+2])/2; index++ } } inputImage = cvCreateImage(cvSize((image[imageIndex+1]->width), image[imageIndex]->height), IPL_DEPTH_8U, 1); cvCopy(images[imageIndex+1], inputImage, 0); } Can somebody, please, explain how can I create this image buffer (images[]) and allocate memory for it. Also how can I access any image in this buffer? Thank you very much in advance!

  • convert pixels into image

    - by Zeta Op
    what i am trying to do is to convert a pixel from a video cam, into an image to expalin it better imagine a 3d model so.. the pixels would be each polying, and i want to do is to conver each polyigon into an image. what i have so far is this ** import processing.video.*; PImage hoja; Capture cam; boolean uno, dos, tres, cuatro; import ddf.minim.*; Minim minim; AudioPlayer audio; float set; void setup() { //audio minim = new Minim(this); // audio = minim.loadFile("audio"); // audio.loop(); // uno=false; dos=false; tres=false; cuatro=true; size(640, 480); hoja=loadImage("hoja.gif"); cam = new Capture(this, width, height); cam.start(); } void draw() { if (cam.available() == true) { cam.read(); if (uno==true) { filtroUno(); image(cam, 0, 0, 640, 480); } if (dos==true) { filtroDos(); } if(tres==true){ filtroTres(); } if(cuatro==true){ filtroCuatro(); image(cam, set, 0,640,480); } } // The following does the same, and is faster when just drawing the image // without any additional resizing, transformations, or tint. //set(0, 0, cam); } void filtroUno() { cam.loadPixels(); hoja.loadPixels(); for (int i=0;i<cam.pixels.length;i++) { if (brightness(cam.pixels[i])>110) { cam.pixels[i]=color(0, 255, 255); } else { cam.pixels[i]=color(255, 0, 0); } } for (int i=0;i<cam.width;i+=10) { for (int j=0;j<cam.height;j+=10) { int loc=i+(j*cam.width); if (cam.pixels[loc]==color(255, 0, 0)) { for (int x=i;x<i+10;x++) { for (int y=j;y<j+10;y++) { // println("bla"); int locDos=i+(j*cam.width); cam.pixels[locDos]=hoja.get(x, y); } } } } } cam.updatePixels(); } ** the broblem is that each pixel is creating me a matrix, so.. is not recreating what id that to do. i had the method filtroUno but it wasn't showing ok.. and was the result void filtroUno() { cam.loadPixels(); hoja.loadPixels(); for (int i=0;i<cam.pixels.length;i++) { if (brightness(cam.pixels[i])>110) { cam.pixels[i]=color(0, 255, 255); } else { cam.pixels[i]=color(255, 0, 0); } } for (int i=0;i<cam.width;i+=10) { for (int j=0;j<cam.height;j+=10) { int loc=i+j*hoja.width*10; if (cam.pixels[loc]==color(255, 0, 0)) { for (int x=i;x<i+10;x++) { for (int y=j;y<j+10;y++) { // println("bla"); int locDos=x+y*hoja.height*10; cam.pixels[locDos]=hoja.get(x, y); } } } } } cam.updatePixels(); } i hope you can help me thanks note: each red pixel should be the gif image the imge size is 10x10

  • How to make background image black-and-white?

    - by Dmitri
    Are there any filters that would make background image to be displayed as black-and-white? What I mean, is this: i have a background image set via css using background: url(/image.png); But now I need to apply a filter so that an image is shown as black-white only. Ideally, I would like to also apply opacity to it. The effect I really trying to achieve is to have background image black/white and on hover over that span element the filter would be removed, revealing the color version. And of cause it has to work in FF, Chrome, IE Can someone help me?

  • RGB values from image into a one dimension array in c#

    - by velocityxyz
    I was wondering if there is a was a way to read rgb values from an image into a one dimensional array in C#. If it doesnt make sense, in java I would do something like this. int[] pixels; BufferedImage image = getClass().getResourceAsStream("asdfghjkl.png"); int w = image.getWidth(); int h = image.getHeight(); pixels = new int[w * h]; image.getRGB(0, 0, w, h, pixels, 0, w) ; So any help would be great, or if you can point me in the right direction, that'd be great

  • How to convert poor quality bitmap image to vector?

    - by Macha
    I'm designing a website for a group which has lost the original digital image for their logo. The only file they have of it is a jpg which was embedded into a word document. The image has everything possible wrong with it: Anti-aliased onto a white background where it should be transparent Image artefacts Resized downwards poorly. Lines that should be straight and solid aren't. I've currently used the wand tool to get rid of the white background, and stuck it on the website, but it's poor quality makes it stick out like a sore thumb. I need a few different sizes of it to use, so how would I go about creating a vector image based on it?

  • Improving Performance on this Image Creation function

    - by Abs
    Hello all, I am making use of GD2 and the image functions to take in a string and then convert that into an image using different fonts at different sizes. The function I use is below. Currently, its pretty quick but not quick enough. The function gets called about 20 times per user and the images generated are always new ones (different) so caching isn't going to help! I was hoping to get some ideas on how to make this function faster. Maybe supply more RAM to the script running? Anything else that is specific to this PHP function? Anything else that I can do to tweak performance of this function? function generate_image($save_path, $text, $font_path, $font_size){ $font = $font_path; /* * I have simplifed the line below, its actually a function that works out the size of the box * that is need for each image as the image size is different based on font type, font size etc */ $measure = array('width' => 300, 'height'=> 120); if($measure['width'] > 900){ $measure['width'] = 900; } $im = imagecreatetruecolor($measure['width'], $measure['height']); $white = imagecolorallocate($im, 255, 255, 255); $black = imagecolorallocate($im, 0, 0, 0); imagefilledrectangle($im, 0, 0, $measure['width'], $measure['height'], $white); imagettftext($im, $font_size, 0, $measure['left'], $measure['top'], $black, $font, ' '.$text); if(imagepng($im, $save_path)){ $status = true; }else{ $status = false; } imagedestroy($im); return $status; } Thanks all for any help

  • SFML: Generate a background image

    - by BlackMamba
    I want to generate a background, which is used in the game, on every instance of the game based on certain conditions. To do so, I'm using a sf::RenderTexture and a sf::Texture like this: sf::RenderTexture image; std::vector<sf::Texture> textures; sf::Texture texture; // instantiating the vector of textures and the image not shown here for (int i = 0; i < certainSize; ++i) { if(certainContition) { texture.setTexture("file"); texture.setPosition(pos1, pos2); } else { ... } image.draw(texture); } The point here is that I draw single textures on a sf::RenderTexture, but because textures always are on the graphic cards memory, I can't exceed a certain map size which I have to. I also considered using an sf::Image, but I can't find a way to draw an image (i.e. a texture) to it. The third way I found was using an sf::VertexArray, but this seems to be a bit too low-level for my rather simple purposes. So is there a common way to dynamically generate a background image based on other existing images?

  • Fastest Algorithm to scale down 32Bit RGB IMAGE.

    - by Sunny
    which algorithm to use to scale down 32Bit RGB IMAGE to custom resolution? Algorithm should average pixels. for example If I have 100x100 image and I want new Image of size 20x50. Avg of first five pixels of first source row will give first pixel of dest, And avg of first two pixels of first source column will give first dest column pixel. Currently what I do is first scale down in X resolution, and after that I scale down in Y resolution. I need one temp buffer in this method. Is there any optimized method that you know?

  • Image Application in WPF and Perfomance.

    - by Harsha
    Hello All, I am planning to build Image processing application using WPF. Brightness /Contrast and Histogram are main operation of this application. I have downloaded the application " Foundations: Bitmaps and Pixel Bits" from http://msdn.microsoft.com/en-us/magazine/cc534995.aspx . But when I tried to open the images which are more than 1200x1600, It is very slow. How to increase the performance. Is any one worked on Image processing in WPF. Please suggest me how to solve this perfomance issue in WPF for image(more than 1600x1200) operation. Thanks you, Harsha

  • WPF / C#: Transforming coordinates from an image control to the image source

    - by Gabriel
    I'm trying to learn WPF, so here's a simple question, I hope: I have a window that contains an Image element bound to a separate data object with user-configurable Stretch property <Image Name="imageCtrl" Source="{Binding MyImage}" Stretch="{Binding ImageStretch}" /> When the user moves the mouse over the image, I would like to determine the coordinates of the mouse with respect to the original image (before stretching/cropping that occurs when it is displayed in the control), and then do something with those coordinates (update the image). I know I can add an event-handler to the MouseMove event over the Image control, but I'm not sure how best to transform the coordinates: void imageCtrl_MouseMove(object sender, MouseEventArgs e) { Point locationInControl = e.GetPosition(imageCtrl); Point locationInImage = ??? updateImage(locationInImage); } Now I know I could compare the size of Source to the ActualSize of the control, and then switch on imageCtrl.Stretch to compute the scalars and offsets on X and Y, and do the transform myself. But WPF has all the information already, and this seems like functionality that might be built-in to the WPF libraries somewhere. So I'm wondering: is there a short and sweet solution? Or do I need to write this myself? EDIT I'm appending my current, not-so-short-and-sweet solution. Its not that bad, but I'd be somewhat suprised if WPF didn't provide this functionality automatically: Point ImgControlCoordsToPixelCoords(Point locInCtrl, double imgCtrlActualWidth, double imgCtrlActualHeight) { if (ImageStretch == Stretch.None) return locInCtrl; Size renderSize = new Size(imgCtrlActualWidth, imgCtrlActualHeight); Size sourceSize = bitmap.Size; double xZoom = renderSize.Width / sourceSize.Width; double yZoom = renderSize.Height / sourceSize.Height; if (ImageStretch == Stretch.Fill) return new Point(locInCtrl.X / xZoom, locInCtrl.Y / yZoom); double zoom; if (ImageStretch == Stretch.Uniform) zoom = Math.Min(xZoom, yZoom); else // (imageCtrl.Stretch == Stretch.UniformToFill) zoom = Math.Max(xZoom, yZoom); return new Point(locInCtrl.X / zoom, locInCtrl.Y / zoom); }

  • Float PPM image file format?

    - by Luca
    I've found a PPM image with the header starting with PF. The resolution number is stored in floating point (-1.000). No comments are inserted to get how it was produced. From the resolution, each pixel is composed by 12 bytes (4 bytes per component)... I suppose they are float or integer numbers. The problem is that I cannot get a clear image. Someone has already found this kind of images?
