问题 I have problem with conversion color to hexadecimal. Red underline is below System.Drawing.ColorTranslator.FromHtml("paint") and rect.Color; Variable paint is static - for now.

问题 I am migrating an old application and am trying to implement MVVM. The old application has a similar interface to the one described in this post. Although it is slightly simpler. I am not too worried about following MVVM exactly, but I would like to use this as a chance to practice. I have the following class: public class LineViewModel { public ObservableCollection<LinePoint> Points {get;} public Geometry LineGeometry {get;} } In my application view model I have a collection of lines and I

How would I animate the process of a transformed canvas image going back into its original state?

问题 I am at a transform of (1, 0, 0, -0.7, 0.4, 320, 70) and I want to gradually end up at (1, 0, 0, 1, 0, 0), how do I do this? This is the code that transforms the images: document.addEventListener("DOMContentLoaded", function(event) { image = new Image(); image2 = new Image(); image3 = new Image(); image4 = new Image(); window.onload = function() { //first image var width = image.width, height = image.height; canvas1 = document.getElementById("num1Canvas"); bottomSlice = canvas1.getContext("2d

Firefox : canvas.toDataURL in image.onload but returning transparent image

由 梦想的初衷 提交于 2020-01-11 12:52:11

Also have tried {preserveDrawingBuffer : true} in canvas.getContext. This is not working in Firefox but works in Chrome... My code : var imageWidth = imageHeight = 45; var image = new Image(); console.log(image); image.onload = (function (imageWidth, imageHeight) { var canvas = document.createElement('canvas'); d3.select(canvas

问题 How do game manufacturers prevent visitors from seeing the game code by right-clicking on the page in web browsers in popular HTML5/Canvas games?
