I have an HTML with base 64 encoded inline image. I have to display this in an application. I am using NSTextView to display this. Now this works fine in 10.6 but in 10.5 instead of the image I kind of see a placeholder. So I went ahead and tried opening that HTML with Text Edit. The same thing happened. TextEdit on 10.6 is able to render it perfectly but 10.5 TextEdit is just not able to render the image.
Can some one please tell me what could be wrong. The HTML is like -
<html>
<head>..</head>
<body><p>
<img width="213" height="123" src="data:image/jpg;base64,/9j/....."alt="" />
</p>
</body>
</html>
PS: Please dont ask why I am not using WebView. I have to use NSTextView.

I want to add a pdf thumbnail to my ion-scroll view, basically I want to add something like this :
I have tried this code :
<iframe src="img/pdf1.pdf#view=fit,10&toolbar=0" style="width:220px;height:100%"></iframe>
<a href="img/pdf1.pdf" class="loupe">
<img src="img/loupe.png">
</a>
This works only on web browsers not on mobiles.
Any suggestions please?
If you want to open pdf in your app with scroll option, its better way to open pdf in in-app browser
Is there any way of capturing web screnshot in the way that the output will look like the way a website would look using a mobile device, such an iphone?
Iv'e tried using an iphone user-agent, and to use the exact same resolution, but the result is not the same.
Im trying to render a simple page using this html:
<html>
<head>...</head>
<body>
<img src="..." style="400px;height:300px" />
</body>
I know that this code is not responsive. though I would expect phantomjs to render it the way the device renders it.
Thanks
First off I am completely new to Javascript but I have some HTML/CSS experience. I've been trying to create an html/javascript image gallery for a website; (It would probably be a lot easier to do in PHP but the web coordinator disabled PHP on our server for security reasons).
Anyway What I have is a page showing an Album-list, Album-browser and Photo-viewer in different a div and 2 iframes respectively. I have it set up so that when someone clicks on an album from the album list, a page is opened up in the album browser section (iframe:"browser-frame" showing thumbnails of all the images in the particular album). I've been trying to set it up so that when someone clicks on an image in the album browser the image will appear in the Photo-viewer section (iframe:"viewer-frame" showing the photo itself).
I didn't want the photo's in the viewer-frame to be larger than the set dimensions for the viewer-frame so I created a page for the viewer-frame that puts the image in a div with a class of set dimensions (defined in a stylesheet) as follows:
...<body>
<div class="photoview">
<img id="viewed_image" class="large" src="images/album1/1.jpg" />
</div>
</body>...
I then created a script that updates the image src to a variable:image_to_be_viewed and called it image-changer.js
// JavaScript Document
{
var image_to_be_viewed="images/album1/1.jpg";
document.getElementById("viewed_image").src=image_to_be_viewed;
}
And added a script to the viewer-frame page so it looks like:
...<body>
<div class="photoview">
<img id="viewed_image" class="large" src="images/album1/1.jpg" />
<script src="image-changer.js"></script>
</div>
</body>...
Now I wanted the gallery to work so that in the page loaded in the browser-frame, whenever one clicked on one of the pictures, the value of the global variable 'image_to_be_viewed' would be changed to the source of the clicked image as follows:
<body>
<div class="photobrowse">
<img class="medium" src="images/album1/1.jpg" onClick="image_to_be_viewed='images/album1/1.jpg'"/>
<img class="medium" src="images/album1/2.jpg" onClick="image_to_be_viewed='images/album1/2.jpg'"/>
<img class="medium" src="images/album1/3.jpg" onClick="image_to_be_viewed='images/album1/3.jpg'"/>
</div>
</body>
It doesn't work....
the gallery i'm working on is on http://ptc.tamu.edu/test/gallery_directory/test_gallery.html
everything up to the loading of the selected picture in the viewer frame works (I'm running the onlick event on the default loaded pictures 1,2,3 in the browser-frame page)(default pic's 4 and 5 simply load the image in the iframe but with no way to adjust the size it is too big and gets cut off and i don't want that)
I've been working on for an entire day and I'm sure I'm doing something wrong here but I can't figure out what exactly it is. I have a feeling it has to do with changing the global variable: image_to_be_viewed from the browser-frame page but I wanted to confirm with experts instead of flopping about like a headless fish. I'm going to continue trying to figure this out but i thought maybe having some expert assistance would speed up the process.
What the onclick triggers should be a javascript function call.
e.g. onclick="changeImg('images/album1/1.jpg')"
And the function itself should looks like this
function changeImg (image_to_be_viewed) {
document.getElementById("viewed_image").src = image_to_be_viewed;
}
btw, you probably should learn javascript a little bit more before work on something real. I recommend this book
thank you I got it to work! I figured that the changeImg function was targeting the wrong document/wrong frame and I fixed it by changing the js script to:
function changeImg (image_to_be_viewed) {
window.parent.viewer_frame.document.getElementById("viewed_image").src = image_to_be_viewed;
}
I've setup my Rails 3 app with only
<%= yield %>
in the application.html.erb and pages.html.erb layout files (Pages is my controller), and I have a view with only the following:
<!DOCTYPE html>
<html>
<title>My Title</title>
<body>
<iframe src="http://myiframesource.com" seamless="seamless" width="100%" height="1949px"></iframe>
</body>
</html>
But the iframe still has a border around it and does not completely fill the page when I look at it in my browser (I tried several). According to W3Schools http://www.w3schools.com/html5/att_iframe_seamless.asp
the seamless attribute should have no borders nor scrollbars and " should look like it is part of the parent document."
I'd also like to not have to tell the iframe what width/height to be, and just have it take up as much space as it needs.
Why does the seamless attribute seem to not be working right?
That's probably because your browser doesn't support seamless iframes. As far as I know it doesn't work in either Firefox 4 or Google Chromium 11, you'll have to wait until someone actually implements it. As for the iframe taking as much space as it needs I don't think that there is currently a way to do this without JavaScript. For a JavaScript solution just search the web, there are several tutorials about this.
I've built a form, and next to my form element I've placed a flash object. When the page is loaded, the form is display: block, and the flash object is display: none.
The layout looks something like (the img is there so that if the user doesn't have flash, the gif animation will play instead):
<form id="form"></form>
<div id="upload-anim-div">
<object type="application/x-shockwave-flash"
data="<?= PAL_STATIC_HOST ?>/music/introducing/flash/upload_animation.swf"
width="626"
height="600">
<param name="movie" value="<?= PAL_STATIC_HOST ?>/music/introducing/flash/upload_animation.swf"/>
<img src="<?= PAL_STATIC_HOST ?>/music/introducing/img/Anim-placeholder.gif" alt="upload animation (gif)"/>
</object>
</div>
When I submit my form, which is just to upload a file, I hide the form and display my animation div as follows in javascript:
$('#form').hide();
$('#upload-anim-div').show();
This works great in all browsers except Safari, where a big white space appears. Right clicking this white space simply gives me the following menu:
Flash movie not loaded... _not clickable_
About Adobe Flash Player 10.5.blah...
Why is the movie not loaded/loading?! If I simply display the movie when the document first loads (by removing the javascript line that initially hides it) it loads and displays fine! Any ideas would be greatly appreciated!
---EDIT---
I've now tried using swfobject, but get exactly the same problem. I used this kind of code in my javascript to embed my swf with javascript after displaying the upload-anim-div:
swfobject.embedSWF("myContent.swf", "upload-anim-div", "626", "600", "10");
Anyone have any further ideas?
Sounds like Safari tries to shave the page load time by not rendering Flash in a hidden div. How are you putting the Flash into the div, is it just an object tag, or are you using something like swfobject? If you're using swfobject you could write the Flash to the div when you reveal it.
I think you should try to embed your Flash content with swfobject:
