I am trying to append an image after the last input field in a div, any ideas as to why this won't work?
$('<img src="img/loading.gif" id="loading_img" />').appendTo($(form).find('input:last'));
I've looked around a bit for a great JavaScript Sprite Sheet animator lib/engine but couldn't find any good ones so I thought I'd ask around =).
What I'm looking for in the engine is:
Animate an image in a non-canvas setting (ex: div via css or img
tags)
Control frame rate/animation speed
Flags to loop or to animate
once etc.
Are there any engines like this out there? If not I can always make my own but then again, I don't want to re-invent the wheel =].
On some android's native browser touching the page seems to stop the display from being updated until the finger is released. This occurs for both html element based animation (switching classes) and for canvas based animation. It does not however stop normal js execution and other events are fired as normal. On devices with this problem the dolphin browser also seems effected (not firefox though).
Touchstart/move both have preventDefault() fired as well as stopPropergation(), cancelBubble = true; and e.returnValue = false;. In the CSS webkit selection has also been disabled. The page will not scroll.
A similar question has been asked here:
Does Android browser lock DOM on touchStart?
but I'd like to find out if this behaviour can be overcome, or at least to discover what devices will be effected by the problem, is it a device or version android issue? If you cannot answer the question running the demo and reporting your experience along with your device model and useragent (displayed at bottom of demo page) as a comment might help others or myself answer the question.
Here is a demo and steps to reproduce the behaviour. A QR code for the link can be found here https://s3-eu-west-1.amazonaws.com/canvas-test-pd/tmp.png.
https://s3-eu-west-1.amazonaws.com/canvas-test-pd/index.html
The web page has a canvas at the top and a div with a background image at the bottom. Every second the canvas is cleared and a different image displayed and the div has it's class switched (both toggle between 0 and 1 pngs). Once this has toggled a few times place your finger on the canvas (the top grey box) and hold it there. Wait to see if the animation continues (sometimes it will once or twice then stops) and if there are any visual distortions.
Update
It seems that the Galaxy Tab running 3.2 requires handlers for touchstart/end of document, not just required divs for the screen to continue updating the display. Thanks jimpic.
I'm starting to believe it's an issue caused by manufacturers skins, although this is difficult to prove.
Hi I am new in iphone. I want developing a application that we can capture image from iphone camera.
How to do this i am not understand. Plz help me how to do this with source code and link where we can read this.
I have a scroll view with transparent background that covers most of the screen. It also covers some buttons that still need to be tap-able. How can I make sure that the scroll view doesn't respond to touches in regions where the subview image is transparent?
I'm using graphviz to generate a client side imagemap, which generates both the image file and a text file containing the map HTML code. Is there anyway I can dynamically read this file and write this map information onto the HTML page when it loads?
I was trying to implement an image panner I found here
Chrome renders the same document differently depending on the extension of the file requested. I have created a test case, where it works when the file it's not named as test.xhtml
You can download the test case from here
Does anybody know why or how to solve it? I want my files to be .xhtml
In IE and FF it works fine.
Code:
test.html / test.xhtml (change the name to see that works with one but not with the other).

When I select a running instance and click the "instance actions" pull-down, the option to bundle the image to an S3 bucket is grayed out. Why would this be?
See here:

I am signed up for S3, and this is not a windows instance.
I am using Coldfusion to view images stored in the file system and I can READ the EXIF metadata of JPEGs, but I'd like to know if it is possible to modify this information and re-save the image.
I am using wordpress as a full on CMS on a site I am building. One thing I cant seem to figure out is how to link up my navigation bar to the pages I am creating in wordpress. I am using a sprite image hover navbar that is defined in the header.php file.
Does anyone have any idea how I can take a typical CSS sprite navbar and link it up with the pages I am creating within wordpress?
I've written a simple top down parser using c#. It's a console application. I'd like the parser could save, at the end of the computation, an image file of the parse tree. I think I could use graphviz, but I'd like to know your opinion.
Thanks.
I am displaying 5 userImage on one screen.I want to display userID and email on mouseover on those userImage.I used alt property of image control but that not working in mozila,chrome and some versions of IE.
So what are the other better ways to display info on mouseover?
I have an asp.net menu control in my application.Each node is an image of different color and the styles of the subnodes are set in the sitemap.How can I set the mouse hovering of back ground color for each subnode which is of different color?
I have one node(ImageView) that displays an image and another node(rectangle) that resides on top of it. The behavior I need is that when the mouse is dragged(press-drag-release gesture) over the rectangle, both the nodes should move coherently. My thought process goes in the following direction:
• Move both the nodes by the same distance in the direction of the drag.
For this option(maybe there are more options) I need the distance between the start and end of the mouse drags. I tried capturing the start and end coordinates of the drag but have been unsuccessful. I think I am getting lost in which handlers to implement.
The code I have is below:
import javafx.event.EventHandler;
import javafx.geometry.Rectangle2D;
import javafx.scene.image.ImageView;
import javafx.scene.input.MouseEvent;
public class MyView
{
double mouseDragStartX;
double mouseDragEndX;
double mouseDragStartY;
double mouseDragEndY;
ImageView imageView;
public MyView()
{
imageView = new ImageView("C:\\temp\\test.png");
}
private void setRectangleEvents(final MyObject myObject)
{
myObject.getRectangle().setOnMousePressed(new EventHandler<MouseEvent>()
{
@Override
public void handle(MouseEvent mouseEvent)
{
mouseDragStartX = mouseEvent.getX();
mouseDragStartY = mouseEvent.getY();
mouseEvent.consume();
}
});
myObject.getRectangle().setOnMouseReleased(new EventHandler<MouseEvent>()
{
public void handle(MouseEvent mouseEvent)
{
mouseDragEndX = mouseEvent.getX();
mouseDragEndY = mouseEvent.getY();
myObjectDraggedHandler();
}
});
}
private void myObjectDraggedHandler()
{
Rectangle2D viewport = this.imageView.getViewport();
double newX = this.imageView.getImage().getWidth()
+ (mouseDragEndX - mouseDragStartX);
double newY = this.imageView.getImage().getHeight()
+ (mouseDragEndY - mouseDragStartY);
this.imageView.setViewport(new Rectangle2D(newX, newY, viewport.getWidth(), viewport
.getHeight()));
}
}
P.S: This code is just for indicating what I am trying to implement and will not compile correctly.
Or maybe my question should just have been:
How to capture the length or span of a mouse drag?
I assigned these classes menu second_menu menu_about_author to ul so the html code looks like <ul class="menu second_menu menu_about_author"> I wanted this ul to have the same properties like menu and second_menu and then I wanted to move the menu_about_author little bit down.
I did so by .menu_about_author { margin-top:40px; } but it didn't work
any idea why the margin-top:40px; is crossed? the link to the image is [1]: http://img153.imageshack.us/img153/882/58daeef0c3c846e4a8d6321.png
Task: (all in code, not visual) create a canvas, place into it some labels and draw some lines, then cache it as byteArray.
The problem is that if I cache an object that is already drawed on the screen, it works great, but if I cache a canvas, that have been created few lines earlier, this results white image.
Is there any solution to cache a display object, that was created in code, but not intended to be displayed at all?
Is it good to add line-height in body{line-height:1.5} or it would be better if i add separately for tag by tag like p{ line height:1em} etc.
Edit:
body {line-height:in em} create problem with if we put image with float inside
Edit: 24 April 2010:
If i have to add different line heights to elements
like
p { 1.4}
h1 {1.6}
h2 { 1.2}
ul li { 1.1}
then shouldn't i use line height in body { 1.4}
if body { 1.4} and h1 {1.6} then what would be line height for h1?
What actually happens to the .box file (which according to the docs is simply a vbox image in tar form, in a particular format) after the first command
vagrant box add lucid32 http://files.vagrantup.com/lucid32.box
is executed?
I can't seem to find the filesystem location of lucid32.box after the download has successfully completed...
I am aware it doesn't really matter as
vagrant init lucid32
vagrant up
vagrant ssh
will get me into the vm irregardless.
But I am curious where .box is located.
I Use the following code to load png image:
UIImage *imageBack1 = [UIImage imageNamed:@"Bar1.png"];
UIImage *imageBack2 = [UIImage imageNamed:@"Bar2.png"];
imageBack1 work right when imageBack2's value is nil,
Bar1.png and Bar2.png are located at the same place,but why Bar2.png couldn't be load?

I'm aware that OpenGL textures on the the iphone are required to be a power of 2, is this true of OpenGL 2.0 as well? If I have an image that is 320 x 480 in size and want to draw it full screen is there any possible way to do this with OpenGL.
Thanks

I have a semi-transparent PNG as a background image for a div that that I'm placing over some links. As a result, the links aren't clickable. Is there a way I can hover and click "through" the div that's on top? (BTW, to position to foreground div I'm using absolute positioning and z-index.)
Thanks!
Mike
