scaling

I have canvas element and I want to scale it down, but without changing it's js logic. Drawing space in js should always be 600x300px, even if it is displayed in HTML as 300x150px. I know, I can resize image with static resolution, but can I do the same with canvas? Changing the size using CSS scales it Live Demo So basically you set its size for drawing objects, etc, via the width and height properties like so var canvas = document.getElementById("canvas"), ctx = canvas.getContext("2d"); canvas.width = 600; canvas.height = 300; and then change its displayed size using css #canvas{ width:

Is there a way to scale a web page in a UIWebView that maintains the aspect ratio but alleviates the need to scroll horizontally to read an article, for example. Vertical scrolling is fine, I just don't want the user to have to constantly be scrolling back and forth horizontally to read each line of the article. Thanks! Edit: the code I'm using to create the view _webView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, [[self view] frame].size.width, [[self view] frame].size.height)]; [_webView setAutoresizingMask:UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth]; [

I am a R-novice. I want to do some outlier cleaning and over-all-scaling from 0 to 1 before putting the sample into a random forest. g<-c(1000,60,50,60,50,40,50,60,70,60,40,70,50,60,50,70,10) If i do a simple scaling from 0 - 1 the result would be: > round((g - min(g))/abs(max(g) - min(g)),1) [1] 1.0 0.1 0.0 0.1 0.0 0.0 0.0 0.1 0.1 0.1 0.0 0.1 0.0 0.1 0.0 0.1 0.0 So my idea is to replace the values of each column that are greater than the 0.95-quantile with the next value smaller than the 0.95-quantile - and the same for the 0.05-quantile. So the pre-scaled result would be: g<-c(**70**,60,50

I am designing (not programming) a data-series viewer program for medical data, using C#/WPF. There is one main panel which shows the data, with the common mouse pan/zoom functionality (pan with left drag, horizontal zoom with scroll, vertical auto-fit with double click, selection with right drag). The problem is: I need vertical and horizontal grid with rulers on the top/left, similar to those seen in audio-editing (goldwave, audacity), cartography (gpsTrackmaker) and ilustration (photoshop, inkscape) programs. Besides, these rulers are even configurable in most plotting APIs (Matlab, GNUPlot

I'm messing around with QGraphicsView and QGraphicsScene to create a Tic Tac Toe clone. I add some QGraphicsLineItem s to my scene and override the resizeEvent method of the Widget that contains the view, so that when the window is resized, the view and its contents are scaled appropriately. This works fine, except for the first time that I run the program: Once I resize the window by any amount, the scene is scaled correctly: Here's the code: main.cpp: #include <QtGui> #include "TestApp.h" int main(int argv, char **args) { QApplication app(argv, args); TestApp window; window.show(); return
