The simplest way to resize an UIImage?

In my iPhone app, I take a picture with the camera, then I want to resize it to 290*390 pixels. I was using this method to resize the image :

UIImage *newImage = [image _imageScaledToSize:CGSizeMake(290, 390)
                         interpolationQuality:1];    

It works perfectly, but it's an undocumented function, so I can't use it anymore with iPhone OS4.

So... what is the simplest way to resize an UIImage ?

Using jQuery To Get Size of Viewport

How do I use jQuery to determine the size of the browser viewport, and to redetect this if the page is resized? I need to make an IFRAME size into this space (coming in a little on each margin).

For those who don't know, the browser viewport is not the size of the document/page. It is the visible size of your window before the scroll.

How can I resize an image using Java?

I need to resize PNG, JPEG and GIF files. How can I do this using Java?

jQuery - how to wait for the 'end' of 'resize' event and only then perform an action?

So I currently use something like:

$(window).resize(function(){resizedw();});

But this gets called many times while resizing process goes on. Is it possible to catch an event when it ends?

Resize an Image C#

As Size, Width, Height are Get() properties of System.Drawing.Image,
How can I resize an Image object at run-time in C#.

Right now, I am just creating a new Image using:

// objImage is the original Image
Bitmap objBitmap = new Bitmap(objImage, new Size(227, 171));

How can I scale an entire web page with CSS?

Using Firefox, you can enlarge an entire web page by simply pressing CTRL +. What this does is proportionally enlarge the entire web page (fonts, images, etc).

How can I replicate the same functionality using simply CSS?

Is there something like page-size: 150% (which would increase the entire page portions by x%?)

Resize jqGrid when browser is resized?

Is there any way to resize a jqGrid when the browser window is resized? I have tried the method described here but that technique does not work in IE7.

How do I remove minimize and maximize from a resizable window in WPF?

WPF doesn't provide the ability to have a window that allows resize but doesn't have maximize or minimize buttons. I'd like to able to make such a window so I can have resizable dialog boxes.

I'm aware the solution will mean using pinvoke but I'm not sure what to call and how. A search of pinvoke.net didn't turn up any thing that jumped out at me as what I needed, mainly I'm sure because Windows Forms does provide the CanMinimize and CanMaximize properties on its windows.

Could someone point me towards or provide code (C# preferred) on how to do this?

Creating a textarea with auto-resize

There was another thread about this, which I've tried. But there is one problem: the textarea doesn't shrink if you delete the content. I can't find any way to shrink it to the correct size - the clientHeight value comes back as the full size of the textarea, not its contents.

The code from that page is below. I'd appreciate any help or pointers.

function FitToContent(id, maxHeight)
{
   var text = id && id.style ? id : document.getElementById(id);
   if ( !text )
      return;

   var adjustedHeight = text.clientHeight;
   if ( !maxHeight || maxHeight > adjustedHeight )
   {
      adjustedHeight = Math.max(text.scrollHeight, adjustedHeight);
      if ( maxHeight )
         adjustedHeight = Math.min(maxHeight, adjustedHeight);
      if ( adjustedHeight > text.clientHeight )
         text.style.height = adjustedHeight + "px";
   }
}

window.onload = function() {
    document.getElementById("ta").onkeyup = function() {
      FitToContent( this, 500 )
    };
}

Android: Resize a large bitmap file to scaled output file

I have a large bitmap (say 3888x2592) in a file. Now, I want to resize that bitmap to 800x533 and save it to another file. I normally would scale the bitmap by calling Bitmap.createBitmap method but it needs a source bitmap as the first argument, which I can't provide because loading the original image into a Bitmap object would of course exceed the memory (see here, for example).

I also can't read the bitmap with, for example, BitmapFactory.decodeFile(file, options), providing a BitmapFactory.Options.inSampleSize, because I want to resize it to an exact width and height. Using inSampleSize would resize the bitmap to 972x648 (if I use inSampleSize=4) or to 778x518 (if I use inSampleSize=5, which isn't even a power of 2).

I would also like to avoid reading the image using inSampleSize with, for example, 972x648 in a first step and then resizing it to exactly 800x533 in a second step, because the quality would be poor compared to a direct resizing of the original image.

To sum up my question: Is there a way to read a large image file with 10MP or more and save it to a new image file, resized to a specific new width and height, without getting an OutOfMemory exception?

I also tried BitmapFactory.decodeFile(file, options) and setting the Options.outHeight and Options.outWidth values manually to 800 and 533, but it doesn't work that way.

WPF: Setting the Width (and Height) as a Percentage Value

Say I want a TextBlock to have its Width equal to it's Parent container's Width (ie, stretch from side to side) or a percentage of it's Parent Container Width, how can I accomplish this in XAML without specifying absolute values?

I want to do this so that if the Parent Container container is later on expanded (its' Width increased), its' Child Elements will also be expanded automatically. (basically, like in HTML and CSS)

What's the easiest way to resize/optimize an image size with the iPhone SDK?

My application is downloading a set of image files from the network, and saving them to the local iPhone disk. Some of those images are pretty big in size (widths larger than 500 pixels, for instance). Since the iPhone doesn't even have a big enough display to show the image in its original size, I'm planning on resizing the image to something a bit smaller to save on space/performance.

Also, some of those images are JPEGs and they are not saved as the usual 60% quality setting.

How can I resize a picture with the iPhone SDK, and how can I change the quality setting of a JPEG image?

Scale image to fit a bounding box

Is there a css-only solution to scale an image into a bounding box (keeping aspect-ratio)? This works if the image is bigger than the container:

img {
  max-width: 100%;
  max-height: 100%;
}

Example:

• Use case 1 (works): http://jsfiddle.net/Jp5AQ/2/
• Use case 2 (works): http://jsfiddle.net/Jp5AQ/3/

But I want to scale up the image until a dimension is 100% of the container.

• Use case 3 (doesn't work): http://jsfiddle.net/Jp5AQ/4/

Image resizing client-side with javascript before upload to the server

I would like to know if it is technically possible to resize an image at a client-side with javascript (really resize, not just change width and height). I know it's possible to do it in flash but I would like to avoid it if possible. Is there any open source algorithm somewhere on the web?
