scale

问题 I am scaling my webview to fit the content to the width of the screen using the following code: webView.getSettings().setLoadWithOverviewMode(true); webView.getSettings().setUseWideViewPort(true); webView.getSettings().setBuiltInZoomControls(true); This works but now I am getting an empty space at the bottom of the content. The size (in height) of the empty space is directly proportional to the magnitude of the zoom it is doing. So for smaller devices, the size is greater. My feeling is that

问题 The documentation states: "Precision can range from 1 to 38. Scale can range from -84 to 127". How can the scale be larger than the precision? Shouldn't the Scale range from -38 to 38? 回答1: The question could be why not ? Try the following SQL. select cast(0.0001 as number(2,5)) num, to_char(cast(0.0001 as number(2,5))) cnum, dump(cast(0.0001 as number(2,5))) dmp from dual What you see is that you can hold small numbers is that sort of structure It might not be required very often, but I'm

问题 I understand that scaling means centering the mean(mean=0) and making unit variance(variance=1). But, What is the difference between preprocessing.scale(x) and preprocessing.StandardScalar() in scikit-learn? 回答1: Those are doing exactly the same, but: preprocessing.scale(x) is just a function, which transforms some data preprocessing.StandardScaler() is a class supporting the Transformer API I would always use the latter, even if i would not need inverse_transform and co. supported by

问题 How to relative scale size of User Control like image (in image editor). Example (100%): (source: stegnar.com) Scaled down UC (70%): (source: stegnar.com) Well I achieve this in picture editor, but I would like in WPF. :) I need this to adjust my application to different screen resolution, while nothing hiding (no scrollbars). 回答1: You could try the ViewBox control that scales up/down its content so that it fills the available space. <Window x:Class="WpfApplication1.Window1" xmlns="http:/

问题 This question already has answers here : Scaled Bitmap maintaining aspect ratio (12 answers) Closed 5 years ago . I have a custom view (1066 x 738), and I am passing a bitmap image (720x343). I want to scale the bitmap to fit in the custom view without exceeding the bound of the parent. I want to achieve something like this: How should I calculate the bitmap size? How I calculate the new width/height: public static Bitmap getScaledBitmap(Bitmap b, int reqWidth, int reqHeight) { int bWidth = b

问题 Is there a way with CSS or otherwise of making an image fit within an area. Lets say I have multiple images of different sizes and I want them all to fit within a div of 150px by 100px. I don't want to scale the images though as some may be tall and others narrow I simply want them to fit within this area with the rest hidden. I thought about using overflow:hidden but it appears to not be hidden in IE6. Any ideas? 回答1: You should try using this: img{ width: auto; max-width: 150px; height:

问题 I'm trying to create image in QT (inside label) that would change size according to changes in window size, but also would keep aspect ratio. What's the best way to do it? 回答1: You tagged this question with linux. I develop on Windows 10 - the closest to Linux I have at hand is cygwin. Thus, I solved it in VS2013 but, hey, this is C++ with Qt. It should be portable... Actually, QPixmap::scaled() has everything built-in what's necessary for scaling by keeping the aspect ratio. Thus, my

问题 I have implemented a long onDraw method which draws a set of rectangles. The rectangles are too small and I want them to appear bigger. But unfortunately I can't change the rectangle coordinates because they are stored in a database. So is there any way I can zoom in the canvas using canvas.scale() ? 回答1: I'm going to preface this answer by saying you will need to draw everything at 0,0 and then scale it, and finally translate it to behave properly. Simply do the following in your onDraw

问题 Any ideas on how can I insert a scale bar in a map in matplotlib that shows the length scale? something like the one I have attached. Or maybe any ideas on measuring and showing distances automatically (not drawing an arrow and writing the distance manually!)? Thanks :) 回答1: There is a an already existing class for scalebars in matplotlib called AnchoredSizeBar. In the below example AnchoredSizeBar is used to add a scalebar to an image (or map over a 100x100 meter area of randomness). import

问题 I want to move some view from any position to center of screen and scale in parallel. If that's too complicated, translate and scale sequentially is also acceptable. But neither I could achieve. I think it's the problem with the pivot point. But sorry I found no solution. Please help. Maybe it's easy to those who develop games, about which I did nothing. Below is my code: private void moveViewToScreenCenter( final View view ){ DisplayMetrics dm = new DisplayMetrics(); getWindowManager()
