My code works fine for normal devices but creates blurry images on retina devices.

Does anybody know a solution for my issue?

    + (UIImage *) imageWithView:(UIView *)view
    {
    	UIGraphicsBeginImageContext(view.bounds.size);
    	[view.layer renderInContext:UIGraphicsGetCurrentContext()];
	
    	UIImage * img = UIGraphicsGetImageFromCurrentImageContext();
	
    	UIGraphicsEndImageContext();
	
    	return img;

I have the following column specified in a database: decimal(5,2)

How does one interpret this?

According to the properties on the column as viewed in SQL Server Management studio I can see that it means: decimal(Numeric precision, Numeric scale).

What do precision and scale mean in real terms?

It would be easy to interpret this as a decimal with 5 digits and two decimals places...ie 12345.12

P.S. I&#39;ve been able to determine the correct answer from a colleague but had great difficulty finding an answer online. As such, I&#39;d like to have the question and answer documented here on stackoverflow for future reference.

How do I interpret precision and scale of a number in a database?

I&#39;m looking for an optimal way to resize wrapping text in a `TextView` so that it will fit within its getHeight and getWidth bounds. I&#39;m not simply looking for a way to wrap the text- I want to make sure it both wraps and is small enough to fit entirely on the screen. 

I&#39;ve seen a few cases on StackOverflow where auto resizing was needed, but they are either very special cases with hack solutions, have no solution, or involve re-drawing the `TextView` recursively until it is small enough (which is memory intense and forces the user to watch the text shrink step-by-step with every recursion). 

But I&#39;m sure somebody out there has found a good solution that doesn&#39;t involve what I&#39;m doing: writing several heavy routines that parse and measure the text, resize the text, and repeat until a suitably small size has been found. 

What routines does `TextView` use to wrap the text? Couldn&#39;t those be somehow used to predict whether text will be small enough?

**tl;dr**: is there a best-practice way to auto-resize a `TextView` to fit, wrapped, in its getHeight and getWidth bounds?

How to fit an image of random size to an `ImageView`?&lt;br/&gt;
When:

 - Initially `ImageView` dimensions are 250dp *  250dp
 - The image&#39;s larger dimension should be scaled up/down to 250dp
 - The image should keep its aspect ratio
 - The `ImageView` dimensions should match scaled image&#39;s dimensions after scaling

E.g. for an image of 100*150, the image and the `ImageView` should be 166*250.&lt;br/&gt;
E.g. for an image of 150*100, the image and the `ImageView` should be 250*166. 

If I set the bounds as

    &lt;ImageView
        android:id=&quot;@+id/picture&quot;
        android:layout_width=&quot;250dp&quot;
        android:layout_height=&quot;250dp&quot;
        android:layout_gravity=&quot;center_horizontal&quot;
        android:layout_marginTop=&quot;20dp&quot;
        android:adjustViewBounds=&quot;true&quot; /&gt;


images fit properly in the `ImageView`, but the `ImageView` is always 250dp * 250dp.

Fit image into ImageView, keep aspect ratio and then resize ImageView to image dimensions?

In [matplotlib][1], I can set the axis scaling using either [`pyplot.xscale()`][2] or [`Axes.set_xscale()`][3]. Both functions accept three different scales: `&#39;linear&#39;` | `&#39;log&#39;` | `&#39;symlog&#39;`.

What is the difference between `&#39;log&#39;` and `&#39;symlog&#39;`? In a simple test I did, they both looked exactly the same.

I know the documentation says they accept different parameters, but I still don&#39;t understand the difference between them. Can someone please explain it? The answer will be the best if it has some sample code and graphics! (also: where does the name &#39;symlog&#39; come from?)

I want to plot a graph with one logarithmic axis using matplotlib. 

I&#39;ve been reading the docs, but can&#39;t figure out the syntax. I know that it&#39;s probably something simple like `&#39;scale=linear&#39;` in the plot arguments, but I can&#39;t seem to get it right


Sample program: 

    import pylab
    import matplotlib.pyplot as plt
    a = [pow(10, i) for i in range(10)]
    fig = plt.figure()
    ax = fig.add_subplot(2, 1, 1)
    
    line, = ax.plot(a, color=&#39;blue&#39;, lw=2)
    pylab.show()

I have an ImageView and I do a simple scale animation to it. Very standard code.

My scale_up.xml:

    &lt;set xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;&gt;
        &lt;scale android:fromXScale=&quot;1&quot;
               android:fromYScale=&quot;1&quot;
               android:toXScale=&quot;1.2&quot;
               android:toYScale=&quot;1.2&quot;
               android:duration=&quot;175&quot;/&gt;
    &lt;/set&gt;

My animation code:

    Animation a = AnimationUtils.loadAnimation(this, R.anim.scale_up);
    ((ImageView) findViewById(R.id.circle_image)).startAnimation(a);

The problem:

When the image scales it doesn&#39;t scale from the center, but from the top left corner. In other words, the scaled version of the image doesn&#39;t have the same point as the center, but it has the same top-left point. 
Here&#39;s an image that explains what I mean:

[![How the animation scales][1]][1]
[![How I want it][2]][2]

The first image is how the animation scales and the second image is how I want it to scale. It should keep the center point the same. 
I have tried setting up gravity on the image, on the container, aligning left or right, it always scales the same.

I&#39;m using RelativeLayout for the main screen and ImageView is located into another RelativeLayout, but I tried other layouts, no change.

        &lt;/android.support.constraint.ConstraintLayout&gt;
    
    &lt;/RelativeLayout&gt;

I am not sure how the app:layout_constraintDimensionRatio works. My understanding is the ratio will always be width:height. So 3:1 will always make the ImageView appear 3 times wider than height. The prefix H or W tells ConstraintLayout which dimension should respect the ratio. If it is H then it means width will be first computed from other constraints and then height will be adjusted according to the aspect ratio. However this is the result of the layout:

Building a CMS of sorts where the user can move around boxes to build a page layout (basic idea anyway).

I&#39;d like to pull the actual contents in from the database and build out the &quot;page&quot;, but have it display at 50% scale.

I realize I could have 2 sets of CSS - one for the actual front-facing page, and one for the admin tool and just shrink everything accordingly, but that seems like a pain to maintain.

I was hoping there might be some kind of jquery or CSS or something that would allow me to populate a div and give it the properties (?) of 50% scale.

I created a UIButton instance named &quot;button&quot; with an image using `[UIButton setImage:forState:]`. The button.frame is larger than the image&#39;s size.

Now I want to scale this button&#39;s image smaller. I tried changing `button.imageView.frame`, `button.imageView.bounds` and `button.imageView.contentMode`, but all seem ineffective.

    button.imageView.bounds = CGRectMake(0, 0, 70, 70);

and this:

How do I most easily first scale an object, say 2 * times it&#39;s current size and then flip it vertically and horizontally, or both?

As of now, I can either set &quot;scale(2,2)&quot; for it to become 2 times as big as it&#39;s width and height but I can&#39;t flip it at the same with scale(-1, 1) for vertical flip.

I&#39;m trying to understand the definition of `scale` that R provides. I have data (`mydata`) that I want to make a heat map with, and there is a VERY strong positive skew. I&#39;ve created a heatmap with a dendrogram for both `scale(mydata)` and `log(my data)`, and the dendrograms are different for both. Why? What does it mean to scale my data, versus log transform my data? And which would be more appropriate if I want to look at the dendrogram illustrating the relationship between the columns of my data?

Thank you for any help! I&#39;ve read the definitions but they are whooping over my head.

I am trying to get the WebView to have similar behavior as the android browser.  The browser opens all pages in a way that tries to fit their width to the screen.  However, the default behavior of the WebView is to start at a 100% pixel scale so it starts zoomed in on the top left corner.  

I have spent the last couple hours trying to find a way to get the WebView to scale the page to the screen like it does in the browser but I&#39;m not having any luck.  Has anyone found a way to accomplish this?

I see is a setting called setLoadWithOverviewMode, but that didn&#39;t appear to do anything at all.  I also experimented with setInitialScale but on different screen sizes and web page sizes that won&#39;t be as graceful as the browsers scaling.

Any one have any leads?

Thanks

**CSS**
(you really don&#39;t need to know how the pack is done, it&#39;s a lot of css3 for nothing, basically just skew, rotate, scale to make a 3D render from a flat template)

    .quarter.scale-thumb
    {
	-webkit-transform: scale(0.2);
	-moz-transform: scale(0.2);
	-o-transform: scale(0.2);
	transform: scale(0.2);
    }

The plotting code below gives `Error: Discrete value supplied to continuous scale`

What&#39;s wrong with this code? It works fine until I try to change the scale so the error is there... I tried to figure out solutions from similar problem but couldn&#39;t.

The plotting code:

    ## Plotting
    meltDF = melt(df, id.vars = &#39;MW&#39;)
    ggplot(meltDF[meltDF$value == 1,]) + geom_point(aes(x = MW, y = variable)) +
      scale_x_continuous(limits=c(0, 1200), breaks=c(0, 400, 800, 1200)) +
      scale_y_continuous(limits=c(0, 1200), breaks=c(0, 400, 800, 1200))


Here&#39;s how the plot looked before adding scale:

I was looking for some css properties that I never used and came to know about `zoom` property of **css3**

 - What is the similarities and difference between them?

 - When to use Zoom and when scale? Both do pretty much the same job.

 - Which is more efficient to use and why?

##What have I noticed?

 - both scales the object but default transform-origin for scale its center and for zoom its top-left I think;

 - when we use them for scaling on hover, zoom will scale and again shrinks to the original dimension, while scale will only shrink on hover-out.

Zoom Vs. Scale in CSS3

I&#39;m seeing an issue where Chrome and other WebKit browsers massively blur any css-scaled content that also has translate3d applied.

Here&#39;s a JS Fiddle: http://jsfiddle.net/5f6Wg/. (View in Chrome.)

    

&lt;!-- begin snippet: js hide: false console: true babel: false --&gt;

&lt;!-- language: lang-css --&gt;

    .test {
      -webkit-transform: translate3d(0px, 100px, 0px);
    }

    .testInner
    {
      /*-webkit-transform: scale(1.2);*/
      -webkit-transform: scale3d(1.2, 1.2, 1);
      text-align: center;
    }

&lt;!-- language: lang-html --&gt;

    &lt;div class=&quot;test&quot;&gt;
      &lt;div class=&quot;testInner&quot;&gt;
        This is blurry in Chrome/WebKit when translate3d and scale or scale3d are applied.
      &lt;/div&gt;
    &lt;/div&gt;

&lt;!-- end snippet --&gt;

Are there any known workarounds for this? I get that in the simple example above, I could simply use translate rather than translate3d - the point here is to strip the code down to the bare essentials.



WebKit: Blurry text with css scale + translate3d

I have an UIView with around 50 UIButtons. All button positions were given in pixels, relative to the left upper corner of my main UIView.

All (background) images used in the view are available in higher resolution. As I am porting my app from iPhone to iPad, I would like to increase the effective pixel size of the UIView.

Now I&#39;m searching a way to upscale the whole UIView by a factor of 2*. Is that possible without destroying the position of the inner elements?

FYI, the UIView is designed in a NIB-file in XCode. But I don&#39;t mind if it can be done programmatically.
