panning

问题 I'm having trouble fixing panning in this example - it works fine unless you move the zoomed image and then zoom again(offset is set to default value and the view jumps to initial position - http://jsfiddle.net/p2Qzg/). Any ideas on how to fix that? I've been trying to solve that for three days now, without any good results. var canvas= document.getElementById("myCanvas"); canvas.width = window.innerWidth; canvas.height = window.innerHeight; var stage = new createjs.Stage("myCanvas");

问题 I want to pan while zooming into a Mandelbrot set so that the fractal portion of the function stays within the window. The code outputs a series of png images to later be made into a video. Right now, I have the zooming and panning working but I do not know how to adjust the panning while the function is zooming. import numpy as np import matplotlib.pyplot as plt from os import path #6:36 @2560x1440 500 iter #2:51 @2560x1440 200 iter #0:56 @2560x1440 50 iter #1:35 @2560x1440 100 iter #0:53

问题 What are the necessary maths to achieve the camera panning effect that's used in 3ds max? In 3ds max the distance between the cursor and the mesh will always remain the same throughout the entire movement (mouse_down+mouse_motion+mouse_up). My naive and failed attempt has been trying to move the camera on the plane XY by using dt (frame time) multiplied by some hardcoded constant and the result is really ugly and uintuitive. The code I've got so far is: def glut_mouse(self, button, state, x,

问题 I'm trying to create an application with a zoomable/pannable canvas. Features : zoom in/out with mouse wheel at pivot points drag nodes around on the canvas with left mouse button drag the entire canvas with right mouse button The zooming at the pivot point works as long as you start the zooming at scale 1. Position the mouse over a grid point and scroll the mouse wheel. The pivot point will remain where you started zooming. Problem : When you zoom in, then move the mouse to another point and

问题 I want to implement a panning pictureBox in C# winforms. I have a panel on which the autoScroll property is set to true. Within the panel I have my pictureBox whose sizeMode is set to autoSize. On the pictureBox I am listening to mouse events like so: private void pictureBox1_MouseDown(object sender, MouseEventArgs e) { if (e.Button == MouseButtons.Left) { dragging = true; start = new Point(e.Location.X + pictureBox1.Location.X, e.Location.Y + pictureBox1.Location.Y); } } private void

问题 I have a web app with a list of GPS-check-ins from field agents. I would like to pan/zoom the current map/view when a check-in item from the list is clicked. I have setup the leaflet map and click event like so: function checkin_clicked(dt, mobile, address, lat, lon) { console.log(dt, mobile, address, lat, lon); var html = '<div style="width: 300px;" class="message"><img class="message-avatar" src="media/profile-pics/{mobile}.jpg" alt=""> <a class="message-author" href="#"> {name} </a> <span
