  • Base on User Drawing Create Polygon Body as well Image

    - by Siddharth
    In my game, I want to provide a user with drawing feature. By free hand drawing user create a polygon shape. So in my game implementation I have to create body for all found vertices and I have to generate image based on that polygon shape. So my problem is how to create image that match the user provided vertices. In cocos2d I listen that there is an implementation of something like Image Masking. But I don't understand how that thing I implement in andengnine. Please provide any guidance on how to create image same as user generated polygon shape.

  • Fade portfolio image on hover to reveal a magnifying glass or plus sign etc?

    - by ade123
    Hi, I've seen an interesting image hover effect being used a lot lately and was wondering whether anyone has any tips or advice on how best to create this effect? What I'd like to create is a hover effect, so that when you hover over an image, the image fades and a magnifying glass or similar icon fades in. Highlighting the fact that if you click the image, it will enlarge etc. Here is a nice example of the effect: http://themes.mysitemyway.com/infocus/gallery/portfolio/ Any advice or pointers would be greatly appreciated.

  • How to write a cgi script in perl that accepts output (an image file) from a urlconnection in a Java applet and writes it to the server?

    - by Brad Rock
    I created a Java applet for my web page that creates an image file. I want users to be able to run the applet and create unique images, click a button, and have the image they created be saved to the web server. I think I have the code down for writing the image to a URLconnection in the Java applet itself after having successfully written a file while running the applet on my system rather than the web page and saving a file to the local disk, and then altering a few things to write to a URLConnection instead of to the local disk (although we shall see how that works too). I am now trying to write a cgi script in perl that takes the image output from the URLConnection and writes the image to a file on my web server (note: I am a newbie to perl). I have found many examples of how to do something similar with simple text coming from an applet and then writing it to a text file, but I want to know how to apply the same concept to an image. Particularly, how do I read in the image? I've seen text input get read by using read(STDIN, $some_variable)--does the same thing work with an image? Likewise, how do I write the image file? What function do I use? Thanks for your help. I know that I am rather naive about all of this.

  • openCV Won't copy to image after changed color ( opencv and c++ )

    - by user1656647
    I am a beginner at opencv. I have this task: Make a new image Put a certain image in it at 0,0 Convert the certain image to gray scale put the grayscaled image next to it ( at 300, 0 ) This is what I did. I have a class imagehandler that has constructor and all the functions. cv::Mat m_image is the member field. Constructor to make new image: imagehandler::imagehandler(int width, int height) : m_image(width, height, CV_8UC3){ } Constructor to read image from file: imagehandler::imagehandler(const std::string& fileName) : m_image(imread(fileName, CV_LOAD_IMAGE_COLOR)) { if(!m_image.data) { cout << "Failed loading " << fileName << endl; } } This is the function to convert to grayscale: void imagehandler::rgb_to_greyscale(){ cv::cvtColor(m_image, m_image, CV_RGB2GRAY); } This is the function to copy paste image: //paste image to dst image at xloc,yloc void imagehandler::copy_paste_image(imagehandler& dst, int xLoc, int yLoc){ cv::Rect roi(xLoc, yLoc, m_image.size().width, m_image.size().height); cv::Mat imageROI (dst.m_image, roi); m_image.copyTo(imageROI); } Now, in the main, this is what I did : imagehandler CSImg(600, 320); //declare the new image imagehandler myimg(filepath); myimg.copy_paste_image(CSImg, 0, 0); CSImg.displayImage(); //this one showed the full colour image correctly myimg.rgb_to_greyscale(); myimg.displayImage(); //this shows the colour image in GRAY scale, works correctly myimg.copy_paste_image(CSImg, 300, 0); CSImg.displayImage(); // this one shows only the full colour image at 0,0 and does NOT show the greyscaled one at ALL! What seems to be the problem? I've been scratching my head for hours on this one!!!

  • Top Container Background Problem

    - by Norbert
    Here's a screenshot: http://dl.getdropbox.com/u/118004/Screen%20shot%202010-04-13%20at%202.50.49%20PM.png The red bar on the left is the background I set for the #personal div and I would like it to align to the top of the container, vertically. The problem is that I have a background for the #container-top div on top of the #container div with absolute positioning. Is there any way to move the #personal div up so there would be no space left? HTML <div id="container"> <div id="container-top"></div> <div id="personal"> <h1>Jonathan Doe</h1> <p>Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliqua erat volutpat.</p> </div> <!-- end #personal --> </div> <!-- end #container --> CSS #container { background: url(images/bg-mid.png) repeat-y top center; width: 835px; margin: 40px auto; position: relative; } #container-top { background: url(images/bg-top.png) no-repeat top center; position: absolute; height: 12px; width: 835px; top: -12px; } #container-bottom { background: url(images/bg-bottom.png) no-repeat top center; position: absolute; height: 27px; width: 835px; bottom: -27px; } #personal { background: url(images/personal-info.png) no-repeat 0px left; }

  • Is their an optimal config/format for a TIFF when using Tesseract or other OCR?

    - by Zando
    I'm having a bizarre problem with Tesseract. I have a name, "Janice" that is in a 200x40 pixel tiff, that Tesseract interprets as a blank. I'm running hundreds of names through Tesseract and they are processed fine. What I'm actually doing, though, is breaking up a larger TIFF into smaller tiffs of one word each. In the larger TIFF, tesseract recognizes "Janice". What could cause it to hiccup in a TIFF that solely contains that word (and there's enough space around the word to not truncate any of the pixels)? I'm using ImageMagick to split the big TIFF, are there options I should set when reconstituting the new TIFF files?

  • 3D effect to distort paper

    - by donpal
    This may be a little hard to describe since I don't have a sample. I'm trying to find a math function or full 3d function in php or a similar language that can help me with the following effect: imagine if you were to take a flat sheet or paper and glue it on a glass of water. It wouldn't be flat any more. It would have a curve, and one of its sides might end up being slightly hidden. Anyone can refer me to a good library or resource on the web where such functions can be found?

  • How would I detect horizontal-black lines using ImageMagick?

    - by Zando
    So I have what is essentially a spreadsheet in TIFF format. There is some uniformity to it...for example, all the column widths are the same. I want to de-limit this sheet by those known-column widths and basically create lots of little graphic files, one for each cell, and run OCR on them and store it into a database. The problem is that the horizontal lines are not all the same height, so I need to use some kind of graphics library command to check if every pixel across is the same color (i.e. black). And if so, then I know I've reached the height-delimiter for a cell. How would I go about doing that? (I'm using RMagick)

  • How to correctly cache images

    - by James Simpson
    I just installed Google's Page Speed plugin to Firebug, and everything looks good except for caching. I have set headers to cache my JS and CSS files, but it says the images aren't being cached. How can I make sure the images get cached for 30 days? These are static images, so I can't just add the headers with PHP like I did with the other files.

  • Generating two thumbnails from the same image in Django

    - by Titus
    Hello, this seems like quite an easy problem but I can't figure out what is going on here. Basically, what I'd like to do is create two different thumbnails from one image on a Django model. What ends up happening is that it seems to be looping and recreating the same image (while appending an underscore to it each time) until it throws up an error that the filename is to big. So, you end up something like: OSError: [Errno 36] File name too long: 'someimg________________etc.jpg' Here is the code: def save(self, *args, **kwargs): if self.image: iname = os.path.split(self.image.name)[-1] fname, ext = os.path.splitext(iname) tlname, tsname = fname + '_thumb_l' + ext, fname + '_thumb_s' + ext self.thumb_large.save(tlname, make_thumb(self.image, size=(250,250))) self.thumb_small.save(tsname, make_thumb(self.image, size=(100,100))) super(Artist, self).save(*args, **kwargs) def make_thumb(infile, size=(100,100)): infile.seek(0) image = Image.open(infile) if image.mode not in ('L', 'RGB'): image.convert('RGB') image.thumbnail(size, Image.ANTIALIAS) temp = StringIO() image.save(temp, 'png') return ContentFile(temp.getvalue()) I didn't show imports for the sake of brevity. Assume there are two ImageFields on the Artist model: thumb_large, and thumb_small. If this isn't the correct way to do it, I'd appreciate any feedback. Thanks!

  • How to include many "sub"-queries in a SQL statement to generate file paths for images?

    - by Zachary
    Greetings, I have three fields in legacy MySQL database/application. image_type image_of_bush image_prefix I need to extract the data into a full image file path, into a .CSV file, where each combination (mentioned below) is a column. Can it all be done in SQL? Or can you recommend a better way? Currently using PHP to display the combinations on the product page. this is also part of a larger query, which is extracting data from an OS Commerce mySQL database. CASE ONE One Horizontal Image image_type = "Horizontal Image" image_of_bush = "No Image of Bush" IMAGE NAME: image_prefix + _s + .jpg (Example: Albertine_s.jpg) CASE TWO One Vertical Image image_type = "Vertical Image" image_of_bush = "No Image of Bush" IMAGE NAME: image_prefix + _v + .jpg (Example: Albertine_v.jpg) CASE THREE Two Horizontal Images image_type = "Horizontal Image" image_of_bush = "Horizontal Image of Bush" FIRST IMAGE NAME: image_prefix + _s + .jpg (Example: Albertine_s.jpg) SECOND IMAGE NAME: image_prefix + _bs + .jpg (Example: Albertine_bs.jpg) CASE FOUR Two Vertical Images image_type = "Vertical Image" image_of_bush = "Vertical Image of Bush" FIRST IMAGE NAME: image_prefix + _v + .jpg (Example: Albertine_v.jpg) SECOND IMAGE NAME: image_prefix + _bv + .jpg (Example: Albertine_bv.jpg) CASE FOUR One Horizontal and One Vertical Image image_type = "Horizontal Image" image_of_bush = "Vertical Image of Bush" FIRST IMAGE NAME: image_prefix + _s + .jpg (Example: Albertine_s.jpg) SECOND IMAGE NAME: image_prefix + _bv + .jpg (Example: Albertine_bv.jpg) CASE FIVE One Vertical and One Horizontal Image image_type = "Vertical Image" image_of_bush = "Horizontal Image of Bush" FIRST IMAGE NAME: image_prefix + _v + .jpg (Example: Albertine_v.jpg) SECOND IMAGE NAME: image_prefix + _bs + .jpg (Example: Albertine_bs.jpg)
