    convert input.gif -coalesce -repage 0x0 -crop WxH+X+Y +repage output.gif

- Animated gifs are often optimised to save space, but imagemagick doesn&#39;t seem to consider this when applying the crop command and treats each frame individually. `-coalesce` rebuilds the full frames.
- Other commands will take into consideration the offset information supplied in the original gif, so you need to force that to be reset with `-repage 0x0`.
- The crop itself is straightforward, with width, height, x offset and y offset supplied respectively. For example, a crop 40 wide and 30 high at an x offset of 50 = 40x30+50+0.
- Crop does not remove the canvas that it snipped from the image. Applying `+repage` after the crop will do this.

Even with the coalesce and repage, I could not get ImageMagick to crop and resize animated gifs very well.

I found a program called [Gifsicle][1] and it works great for manipulating animated gifs.

    gifsicle --crop 0,0-100,100 --output out.gif in.gif

It can also do all sorts of other operations. Check it out!

Animations are often optimized, which means that some frames are smaller than others. So in ImageMagick you probably want to coalesce the animation before cropping.

    convert in_animation.gif -coalesce -crop WxH+X+Y +repage -layers optimize out_animation.gif

&lt;br&gt;
You may need to add a -dispose method before reading the input animation to avoid a flicker. Also set the -delay and -loop at the end, if you want to make changes.

See

http://www.imagemagick.org/Usage/anim_basics/#dispose
http://www.imagemagick.org/Usage/anim_basics/#coalesce
http://www.imagemagick.org/script/command-line-options.php#layers

The following line worked with me on Mac
    
    convert -dispose 2 input.gif -trim -layers TrimBounds animation.gif

How to assign padding to Listview item divider line

I&#39;m writing a password verify directive :


 
     Directives.directive(&quot;passwordVerify&quot;,function(){
        return {
            require:&quot;ngModel&quot;,
            link: function(scope,element,attrs,ctrl){
                ctrl.$parsers.unshift(function(viewValue){
                    var origin = scope.$eval(attrs[&quot;passwordVerify&quot;]);
                    if(origin!==viewValue){
                        ctrl.$setValidity(&quot;passwordVerify&quot;,false);
                        return undefined;
                    }else{
                        ctrl.$setValidity(&quot;passwordVerify&quot;,true);
                        return viewValue;
                    }
                });
    
            }
        };
    });

html :

    

    &lt;input data-ng-model=&#39;user.password&#39; type=&quot;password&quot; name=&#39;password&#39; placeholder=&#39;password&#39; required&gt;
    &lt;input data-ng-model=&#39;user.password_verify&#39; type=&quot;password&quot; name=&#39;confirm_password&#39; placeholder=&#39;confirm password&#39; required data-password-verify=&quot;user.password&quot;&gt;


Given 2 password fields in a form, if both password values are equal then the field affected  by the directive is valid.
The issue is that it works one way (i.e. when I type a password in the password-verify field). However, when the original password field is updated, the password-verify doesn&#39;t become valid. 

Any idea how I could have a &quot;two way binding verify?&quot;

There&#39;s plenty of information about cropping images, but attempting to crop (or trim) animations produces strange results. Sometimes they flicker, or come with extra frames, or some frames crop correctly and others become offset. How do I prevent all this from happening?

I want to convert different image formats (bmp,jpg,gif,png,tiff-incluging multipaged) into a PDF format with A4 page size and with images fit to page (resized if necessary). Image should be positioned at the center of the page and I&#39;d like to define an offset. 
I tried the code below but there is no offset at the top and the image quality is really poor.


    convert png.png -gravity North -resize 500x500 -quality 100 -page a4x5x5 myout.pdf

Is there any way to do that?

I know that it is impossible to actually modify an image with CSS, which is why I put crop in quotes. 

What I&#39;d like to do is take rectangular images and use CSS to make them appear square without distorting the image at all.

How to fit Image into ImageView using Glide

I have a series of user-customized images within an iOS app that are being animated in a simple, frame-by-frame flip book style.  

My question is this: is there a way to allow users to export their animation as an animated gif?  Ideally, I&#39;d like to enable them to email, social share (T/FB) or (worst case..) save an animated gif to their documents folder for retrieval via iTunes.   

I know how to save a .png to the photo library, and I found a way to record an animation as a QT file (http://www.cimgf.com/2009/02/03/record-your-core-animation-animation/), but I haven&#39;t found a way to just kick out a plain old animated gif.  Am I missing something in Core Animation or somewhere else? Are there any approaches, frameworks, or resources that anyone can recommend?  Sorry if the question is too general - struggling to find a starting point.
