  • WYSIWYG View Editor in 'Android'?

    - by user262122
    Duplicate: Is there any form designer available for Google Android? I would like to move a CheckBox, so it displays in a different location than the top-left corner under Absolute Layout inside main.xml, for 'Android'. I'm using Eclipse to edit my views. How would I do this? On an iPhone they have a tool called Interface builder that allows you to move things in a WYIWYG fashion. Does Eclipse have similar functionality? Regards ShotSimon

  • Capture Video of Android's Screen

    - by Taranfx
    Forget screenshots, is it posible to capture a video of the running application in android? Rooted or non-rooted, I don't care, I want atleast 15fps. Update: I don't want any external hardware. The intent is to make it perfectly portable and every frame is captured within Android OS. If it crosses the boundaries of the app sdk, I'm willing to go to OS level modifications but I would need a starting point.

  • openCV center of image rotation in C

    - by user1477955
    I want to rotate 90 degrees counterclockwise, but it seems the rotation point is wrong. How do I find the rotation center of the source image? img=cvLoadImage(argv[1],-1); height = img->height; width = img->width; step = img->widthStep; channels = img->nChannels; data = (uchar *)img->imageData; IplImage *rotatedImg = cvCreateImage(cvSize(height,width), IPL_DEPTH_8U,img->nChannels); CvPoint2D32f center; center.x = width/2; center.y = height/2; CvMat *mapMatrix = cvCreateMat( 2, 3, CV_32FC1 ); cv2DRotationMatrix(center, 90, 1.0, mapMatrix); cvWarpAffine(img, rotatedImg, mapMatrix, CV_INTER_LINEAR + CV_WARP_FILL_OUTLIERS, cvScalarAll(0)); cvShowImage("My image", rotatedImg );

  • Image expire time

    - by Jens
    The google page speed tool recommends me to set 'Expires' headers for images etc. But what is the most efficient way to set an Expires header for an image? In now redirect all image requests to an imagehandler.php using htaccess: /* HTTP/1.1 404 Not Found, HTTP/1.1 400 Bad Request and content type detection stuff ... */ header( "Content-Type: " . $content_type ); header( "Cache-Control: public" ); header( "Last-Modified: ".gmdate("D, d M Y H:i:s", filemtime($path))." GMT"); header( "Expires: ". date("r",time() + (60*60*24*30))); readfile( $path ); But of course this adds extra loading time for my images on first request, and I was wondering if there was a better solution for this.

  • Right align text in an image with imagettftext(), PHP

    - by James Simpson
    I am setting up dynamic forum signature images for my users and I want to be able to put their username on the image. I am able to do this just fine, but since usernames are different lengths and I want to right align the username, how can I go about doing this when I have to set x & y coordinates. $im = imagecreatefromjpeg("/path/to/base/image.jpg"); $text = "Username"; $font = "Font.ttf"; $black = imagecolorallocate($im, 0, 0, 0); imagettftext($im, 10, 0, 217, 15, $black, $font, $text); imagejpeg($im, null, 90);

  • Photo sharing social platform [closed]

    - by user1696497
    I am working on a photo sharing social platform like Flickr, Photobucket. To start off with I have half a million photos as of now. I want to convert all of these into a single format, compression ratio and use it as an original image. I will be storing original image, re-sized image according to layout and a thumbnail. I have started off with ruby, didn't find supporting libraries. I am considering python as it has a good image processing library and instagram is using it. I want some advise about how the image has to be processed while uploading, efficient way of storage whether database or a file system, image compressions, and precautions to be taken. I would be having profile pictures, do I need store them separately or along with the images? If I want to store the images on a file system, which file system should I use and also should I store the url or should I use any intermediate key value store like redis?

  • divide the image into 3*3 blocks

    - by Jayanth Silesh
    I have a matrix that does not happen to have dimensions that are multiples of 3 or it might. How can we divide the entire image into blocks of 3*3 matrices. (Can ignore the last ones which does not come under the 3*3 multiples. Also, the 3*3 matrices can be be saved in arrays. a=3; b=3; %window size x=size(f,1)/a; y=size(f,2)/b; %f is the original image m=a*ones(1,x); n=b*ones(1,y); I=mat2cell(f,m,n);

  • iPhone/Android app development tutorials?

    - by Decipher
    Hi, I'm looking at jumping on the band-wagon and knock out a couple iPhone and Android apps.

  • Launching and Intent from file and mime type

    - by stonedonkey
    I've reviewed all the similar questions here, but I can't for the life of me figure out what I'm doing wrong. I've written an application that tries to launch various files, sort of a file browser, when a file is clicked it tries to launch the program based on it's associated MIME type or I want it to present the "Choose Application to Launch" dialog. Here's the code I'm using to launch: File file = new File(app.mediaPath() + "/" +_mediaFiles.get(position)); Intent myIntent = new Intent(android.content.Intent.ACTION_VIEW); String extension = android.webkit.MimeTypeMap.getFileExtensionFromUrl(Uri.fromFile(file).toString()); String mimetype = android.webkit.MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension); myIntent.setDataAndType(Uri.fromFile(file),mimetype); startActivity(myIntent); This fails and generates a: android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat=file:///file:/mnt/sdcard/roms/nes/Baseball_simulator.nes } Now if I install OI File Manager for instance, it opens instead of this error being thrown, and then if I click the same file from within in it, it launches the approriate dialogs. I have noticed that the MIME type for that particular file fails, but other mime types like .zip do return values. Am I missing something that when the MIME type is null to call a dialog that lets the user select? I've tried other variations of launching the app, including not setting the mime type and only using .setData with no success. The action I want to happen is, a user clicks a file, if it's associated with an application that app launches, if not, the user gets the "Complete action using" dialog with a list of apps. Thanks for any advice.

  • JQuery image gallery non functional fade effects

    - by Robin Knight
    Here is a simple image gallery script for fading in and out divs with background images. It is slow and not working properly. It would appear all images are appearing and disappearing together without any animation This gallery should fade each image out into the next one function gallery() { timerp = window.setInterval(function() { $('.cornerimg').fadeOut(2000); if ($('.cornerimg:visible') == $('.cornerimg').last()) { $('.cornerimg').first().fadeIn(2000); } else { $('.cornerimg').next().fadeIn(2000); }; }, 6000); } } Any ideas what has gone wrong with it?

  • Sharing code between Android and Windows Mobile

    - by reuscam
    I'm doing some initial research on smart phone development, and I noticed that Android and Windows Mobile both support c++ for application development. I was curious if anyone had any experience trying to manage shared files between both Android and Windows Mobile, and to what extent that code can be shared? e.g. no user interface can be shared, but web service and business logic classes can be shared, etc.

  • Android device guidelines/requirements

    - by Ravi Vyas
    Are there any requirements/guidelines for an Android device? like numbers of buttons or minimum buttons required. Also are there any android devices which do not have the menu and back buttons? ( I am aware that no menu/back buttons will kill most of the apps in terms of usability , I just wanted to know more on the topic :-) )

  • django image managment

    - by Andrey
    I'am new in django. In my project I'am working with images. I don't know how to organize the management of images. I need to dynamically upload the pictures and resize them. First question - what is the best way to dynamically upload images with progress bar and without flash? I found this and this, but I believe there is a better way. Second question. I have to save one image in different sizes. I won't use these thumbnails on my pages, but another application will. Many clients could upload images at the same time. This means that I can not resize all the images at the same time. How should I organize this process? Is there are a better ready-to-use solution for image management issue?

  • iPhone to Android Market

    - by BahaiResearch.com
    (I am coming from an iPhone experience) When we create an iPhone app, Apple gives us a http URL that we can put on web pages that when clicked will open iTunes and give the user a chance to buy on their desktop. As Android has no "iTunes" Windows/Mac application on the desktop, what do I link to on my Web pages/email marketing so that users can go and buy the Android apps we are writing? Ian

  • Background image JFrame with content

    - by Petr Safar
    I have a JFrame with BorderLayout, there are panels on all sides (North, East ,...). In the panels there are labels and buttons mostly. Now I want the frame to have a background image, some research told me that i had to change the content pane of my frame. When I try this however, the content gets put in the background and isn't visible. Also, I don't know how to resize the image if the frame is resized. Is there an easy fix for this or will I have to rework most of my code?

  • Flickering Image in Java?

    - by Noah Cagle
    OK so I am coding a game right now to prepair for Ludum Dare SharkJam, and I am using a new method for programming, because the last method I had crashes my PC, so this one should work. Well it does work and all, better too, but the images that I put in it flicker. Here is the whole main class (where the images are drawn) package me.NoahCagle.watermaze; import java.awt.Color; import java.awt.Graphics; import java.awt.Image; import java.awt.image.BufferedImage; import javax.swing.JFrame; import me.NoahCagle.watermaze.entity.EntityShark; import me.NoahCagle.watermaze.entity.Player; import me.NoahCagle.watermaze.input.Keys; import me.NoahCagle.watermaze.map.Map; public class Game extends JFrame { private static final long serialVersionUID = 1L; Map map = new Map(0, 0); Player player = new Player(50, 30); static EntityShark shark = new EntityShark(400, 400); public Image dbImage; public Game() { setSize(800, 600); setDefaultCloseOperation(EXIT_ON_CLOSE); setLocationRelativeTo(null); setVisible(true); setTitle("Water Maze"); setResizable(false); setBackground(Color.blue); addKeyListener(new Keys()); } public static void main(String[] args) { new Game(); Thread s = new Thread(shark); s.start(); } public void paint(Graphics g) { dbImage = new BufferedImage(getWidth(), getHeight(), BufferedImage.TYPE_INT_RGB); g.drawImage(dbImage, map.x, map.y, null); g.drawImage(player.player, player.x, player.y, this); g.drawImage(shark.shark, shark.x, shark.y, this); repaint(); } } What this code does for me is makes the Images work correctly, just flickering, alot. Can anyone help me with my issue? EDIT: I think it has something to do with where I call the repaint method in the paint method, so look there.
