scale

I have an ImageView with scaletype set to matrix, and would like to get a Rect with the bounds of the image after the transformation of the matrix. How do I get such a rect? thanks. ImageView imageView = (ImageView)findViewById(R.id.imageview); Drawable drawable = imageView.getDrawable(); Rect imageBounds = drawable.getBounds(); Then use Matrix.mapRect. 来源： https://stackoverflow.com/questions/8590693/android-how-to-get-bounds-of-imageview-with-matrix

How do I create my own scale() function in d3? I am trying to replace the nice linear scale in d3 d3.scale.linear() with a different function that I would like to create myself. My new scale would be based on a cumulative distribution function, so that the median value would appear in the center of the x axis, and a value that was two standard deviations from the median would appear twice as far from the center of the x axis as something that was one standard deviation from the mean. Here is a link to my jsfiddle page: http://jsfiddle.net/tbcholla/kR2PS/3/ (I would appreciate any other

http://jsfiddle.net/HF57g/ is an example of a single event(blue rect) placed on the timeline. If i zoom into the timeline, rect's placement on the x axis changes in harmony with the ticks on axis. but at the same time, rect is scaled horizontally. if i modify the following section of the code svg.selectAll(".item").attr("transform", "translate(" + d3.event.translate[0]+", 0)scale(" + d3.event.scale+", 1)"); to svg.selectAll(".item").attr("transform", "translate(" + d3.event.translate[0]+", 0)scale(1, 1)"); as in http://jsfiddle.net/HF57g/1/ to disable horizontal scaling, then the rect's

I need to scale the result of glDrawPixels image. I'm drawing a 640x480 pixels image buffer with glDrawPixels in a Qt QGLWidget. I tryed to do the following in PaintGL: glScalef(windowWidth/640, windowHeight/480, 0); glDrawPixels(640,480,GL_RGB,GL_UNSIGNED_BYTE,frame); But it doesn't work. I am setting the OpenGL viewport and glOrtho with the size of the widget as: void WdtRGB::paintGL() { glClear (GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); // Setup the OpenGL viewpoint glMatrixMode(GL_PROJECTION); glLoadIdentity(); glOrtho(0, windowWidth, windowHeight, 0, -1.0, 1.0); glDepthMask(0); /

I'm trying to calculate the right scale to apply to children inside a parent but i can't use calc() inside transform: scale CSS function. I've done this function with javascript but i'm interested in a pure CSS solution to avoid bloating the page with scripts as much as possible. Example: CSS .anyclass{ height:250px; /*this value can change dinamically */ transform:scale(calc(100% / 490 )); /*is using height value*/ } This definition gives back an invalid property value. Other uses like translate: .anyclass{ transform:translate(calc(100% - 50px )); } works with no problem. Is there anyway i

Is there any way to make WPF application get same size at every system scale? When I change Change size of text, apps and other items in windows system setting from 125% (Recommended) to 100% in a Full-HD screen, My WPF application gets too small. To implement independent system scale application I've wrote a function like this to change scaling of my app back to 125%: private void ScaleTo125Percents() { // Change scale of window content MainContainer.LayoutTransform = new ScaleTransform(1.25, 1.25, 0, 0); Width *= 1.25; Height *= 1.25; // Bring window center screen var screenHeight = System

I'm trying to scale an UIView without scaling its subviews, or in my case I just want the subviews to be scaled in one axis. I need these hierarchy because I'm setting some Gesture Recognizers to detect panning and rotation and I want these to happen simultaneously with the parent view. However, I don't want the scaling to happen simultaneously. For some subviews I want it to happen only vertically or horizontally or no scaling at all. Is there a way to control the auto-scaling in an UIView's subviews when using CGAffineTransform on the UIView? If you ensure the autoresizingMask's of subviews
