Hello, this is ГФ.Now that we have the outline of the manga, I imagine that everyone is anxious to start drawing the work. However, before that, I think it is necessary to corroborate some very important points, because if we leave them aside, it is possible that we will spoil the work we have done with so much effort.Additionally, I will refer to two aspects of special importance when making manga in an application or digital program: the “grayscale” and the “monochrome mode”.Click Here for Previous Tutorials.Manga Tutorial for Beginners 01 Process of Manga MakingManga Tutorial for Beginners 02 Let’s Make Outline (Part 1)Manga Tutorial for Beginners 03 Let’s Make Outline (Part 2)Manga Tutorial for Beginners 04 Get Ready to Draw Manga with MediBang Paint!Manga Tutorial for Beginners 05 Let’s Make Name(outline)Manga Tutorial for Beginners 06 Let’s think about frame layout and screen.Manga Tutorial for Beginners 07 Considerations when setting up the canvas.When it comes to manga to be shared only on the web, there are no rules to follow regarding the size or margins of the paper or canvas. However, in the case of contests or doujinshi, there are requirements regarding the size of the canvas. Likewise, there are rules regarding the margins and spaces to be left blank. So, let’s see what the general rules are.Before I start with the explanation, I just want to clarify that I will mention here the rules that apply in Japan.1. Paper or canvas size2.

I know you all have been talking SCORM... but for the tutorial I need to load, we haven't created a quiz feature. (just a few knowledge check slides so I disable reporting. And again, the same issue... Canvas won't load this HTML file. (index.html).... What's interesting though is... I published a "Ch 12" Captivate HTML 5 file... and a "Ch 13" (different project) HTML5 file... Canvas opens the Ch 12 index.html file and all plays well! ... but I published and uploaded the Ch 13 tutorial the same way... HTML5... uploaded to Canvas the same way as the Ch 12 one... It's almost the exact same file size... and Canvas won't open it. --grey wheel of death just keeps spinning... And I'm trying to figure out... why the one will play but not the other?!--I did try with several browsers too... Safari and Firefox will play Ch 12. Chrome didn't seem to like any of them! ... Any ideas on this one?!... the other issue is... I tried the .htm files... and Ch 13 will open if I click that... however... it has embedded videos and for some reason, they won't show up in the .htm file. ... so... without a solution, I just edited a "fail safe" into the slide with the video in Cp.

The image looks good on the screen, if the dots that make up the halftone screen are distorted, when the image is printed it will generate the “moiré” effect. To avoid this, try from the beginning to set up the canvas according to the final print size, and try not to enlarge or shrink the images where we have applied raster.From the next lesson, we will begin to enter fully into the process of drawing manga in monochrome mode.The topic of the next lesson will be “vignette frames and text balloons” See you!”Click Here for Previous Tutorials.Manga Tutorial for Beginners 01 Process of Manga MakingManga Tutorial for Beginners 02 Let’s Make Outline (Part 1)Manga Tutorial for Beginners 03 Let’s Make Outline (Part 2)Manga Tutorial for Beginners 04 Get Ready to Draw Manga with MediBang Paint!Manga Tutorial for Beginners 05 Let’s Make Name(outline)Manga Tutorial for Beginners 06 Let’s think about frame layout and screen.Manga Tutorial for Beginners 07 Considerations when setting up the canvas.「ГФ」ART streetClick here for the collection： can read my manga here → is also a manga that I draw under a different name. →

html5-canvas Tutorial = Media types and the canvas

一、canvas 简介​ 是 HTML5 新增的，一个可以使用脚本(通常为 JavaScript) 在其中绘制图像的 HTML 元素。它可以用来制作照片集或者制作简单(也不是那么简单)的动画，甚至可以进行实时视频处理和渲染。​它最初由苹果内部使用自己 MacOS X WebKit 推出，供应用程序使用像仪表盘的构件和 Safari 浏览器使用。后来，有人通过 Gecko 内核的浏览器 (尤其是 Mozilla和Firefox)，Opera 和 Chrome 和超文本网络应用技术工作组建议为下一代的网络技术使用该元素。​Canvas 是由 HTML 代码配合高度和宽度属性而定义出的可绘制区域。JavaScript 代码可以访问该区域，类似于其他通用的二维 API，通过一套完整的绘图函数来动态生成图形。​ Mozilla 程序从 Gecko 1.8 (Firefox 1.5) 开始支持 , Internet Explorer 从 IE9 开始 。Chrome 和 Opera 9+ 也支持 。二、Canvas基本使用2.1 元素​ 看起来和 标签一样，只是 只有两个可选的属性 width、heigth 属性，而没有 src、alt 属性。​如果不给 设置 widht、height 属性时，则默认 width为300、height 为 150，单位都是 px。也可以使用 css 属性来设置宽高，但是如宽高属性和初始比例不一致，他会出现扭曲。所以，建议永远不要使用 css 属性来设置 的宽高。替换内容​由于某些较老的浏览器（尤其是 IE9 之前的 IE 浏览器）或者浏览器不支持 HTML 元素 ，在这些浏览器上你应该总是能展示替代内容。​支持 的浏览器会只渲染 标签，而忽略其中的替代内容。不支持 的浏览器则 会直接渲染替代内容。用文本替换： 你的浏览器不支持 canvas，请升级你的浏览器。用 替换： 结束标签 不可省略。与 元素不同， 元素需要结束标签()。如果结束标签不存在，则文档的其余部分会被认为是替代内容，将不会显示出来。2.2 渲染上下文(Thre Rending Context)​ 会创建一个固定大小的画布，会公开一个或多个渲染上下文(画笔)，使用渲染上下文来绘制和处理要展示的内容。​ 我们重点研究 2D 渲染上下文。 其他的上下文我们暂不研究，比如， WebGL 使用了基于 OpenGL ES的3D 上下文 ("experimental-webgl") 。var canvas = document.getElementById('tutorial');//获得 2d 上下文对象var ctx = canvas.getContext('2d');2.3 检测支持性var canvas = document.getElementById('tutorial');if (canvas.getContext){ var ctx = canvas.getContext('2d'); // drawing code here} else { // canvas-unsupported code here}2.4 代码模板实例canvas id="tutorial" width="300" height="300">canvas>script type="text/javascript">function draw(){ var canvas = document.getElementById('tutorial'); if(!canvas.getContext) return; var ctx = canvas.getContext("2d"); //开始代码 }draw();script>尝试一下 »2.5 一个简单的例子以下实例绘制两个长方形：实例canvas id="tutorial" width="300" height="300">canvas>script type="text/javascript">function draw(){ var canvas = document.getElementById('tutorial'); if(!canvas.getContext) return; var ctx = canvas.getContext("2d"); ctx.fillStyle = "rgb(200,0,0)"; //绘制矩形 ctx.fillRect (10, 10, 55, 50); ctx.fillStyle = "rgba(0, 0, 200, 0.5)"; ctx.fillRect (30, 30, 55, 50);}draw();script>尝试一下 »三、绘制形状3.1 栅格 (grid) 和坐标空间​如下图所示，canvas 元素默认被网格所覆盖。通常来说网格中的一个单元相当于 canvas 元素中的一像素。栅格的起点为左上角，坐标为 (0,0) 。所有元素的位置都相对于原点来定位。所以图中蓝色方形左上角的坐标为距离左边（X 轴）x 像素，距离上边（Y 轴）y 像素，坐标为 (x,y)。​后面我们会涉及到坐标原点的平移、网格的旋转以及缩放等。3.2 绘制矩形​ 只支持一种原生的图形绘制：矩形。所有其他图形都至少需要生成一种路径 (path)。不过，我们拥有众多路径生成的方法让复杂图形的绘制成为了可能。canvast 提供了三种方法绘制矩形：1、fillRect(x, y, width, height)：绘制一个填充的矩形。2、strokeRect(x, y, width, height)：绘制一个矩形的边框。3、clearRect(x, y, widh, height)：清除指定的矩形区域，然后这块区域会变的完全透明。说明：这 3 个方法具有相同的参数。x, y：指的是矩形的左上角的坐标。(相对于canvas的坐标原点)width, height：指的是绘制的矩形的宽和高。function draw(){ var canvas = document.getElementById('tutorial'); if(!canvas.getContext) return; var ctx = canvas.getContext("2d"); ctx.fillRect(10, 10, 100, 50); ctx.strokeRect(10, 70, 100, 50); }draw();ctx.clearRect(15, 15, 50, 25);四、绘制路径 (path)图形的基本元素是路径。路径是通过不同颜色和宽度的线段或曲线相连形成的不同形状的点的集合。一个路径，甚至一个子路径，都是闭合的。使用路径绘制图形需要一些额外的步骤：创建路径起始点调用绘制方法去绘制出路径把路径封闭一旦路径生成，通过描边或填充路径区域来渲染图形。下面是需要用到的方法：beginPath()新建一条路径，路径一旦创建成功，图形绘制命令被指向到路径上生成路径moveTo(x, y)把画笔移动到指定的坐标(x, y)。相当于设置路径的起始点坐标。closePath()闭合路径之后，图形绘制命令又重新指向到上下文中stroke()通过线条来绘制图形轮廓fill()通过填充路径的内容区域生成实心的图形4.1 绘制线段function draw(){ var canvas = document.getElementById('tutorial'); if (!canvas.getContext) return; var ctx = canvas.getContext("2d"); ctx.beginPath(); ctx.moveTo(50, 50); ctx.lineTo(200, 50); ctx.closePath(); ctx.stroke(); }draw();4.2 绘制三角形边框function draw(){ var canvas = document.getElementById('tutorial'); if (!canvas.getContext) return; var ctx = canvas.getContext("2d"); ctx.beginPath(); ctx.moveTo(50, 50); ctx.lineTo(200, 50); ctx.lineTo(200, 200); ctx.closePath(); ctx.stroke(); }draw();4.3 填充三角形function draw(){ var canvas = document.getElementById('tutorial'); if (!canvas.getContext) return; var ctx = canvas.getContext("2d"); ctx.beginPath(); ctx.moveTo(50, 50); ctx.lineTo(200, 50); ctx.lineTo(200, 200); ctx.fill(); }draw();4.4 绘制圆弧有两个方法可以绘制圆弧：1、arc(x, y, r, startAngle, endAngle, anticlockwise): 以(x, y) 为圆心，以r 为半径，从 startAngle 弧度开始到endAngle弧度结束。anticlosewise 是布尔值，true 表示逆时针，false 表示顺时针(默认是顺时针)。注意：这里的度数都是弧度。0 弧度是指的 x 轴正方向。radians=(Math.PI/180)*degrees //角度转换成弧度2、arcTo(x1, y1, x2, y2, radius): 根据给定的控制点和半径画一段圆弧，最后再以直线连接两个控制点。圆弧案例 1function draw(){ var canvas = document.getElementById('tutorial'); if (!canvas.getContext) return; var ctx = canvas.getContext("2d"); ctx.beginPath(); ctx.arc(50, 50, 40, 0, Math.PI / 2, false); ctx.stroke();}draw();圆弧案例 2function draw(){ var canvas = document.getElementById('tutorial'); if (!canvas.getContext) return; var ctx = canvas.getContext("2d"); ctx.beginPath(); ctx.arc(50, 50, 40, 0, Math.PI / 2, false); ctx.stroke(); ctx.beginPath(); ctx.arc(150, 50, 40, 0, -Math.PI / 2, true); ctx.closePath(); ctx.stroke(); ctx.beginPath(); ctx.arc(50, 150, 40, -Math.PI / 2, Math.PI / 2, false); ctx.fill(); ctx.beginPath(); ctx.arc(150, 150,

100); ctx.lineWidth = 20; ctx.lineCap = lineCaps[i]; ctx.stroke();} ctx.beginPath();ctx.moveTo(0, 30);ctx.lineTo(300, 30); ctx.moveTo(0, 100);ctx.lineTo(300, 100) ctx.strokeStyle = "red";ctx.lineWidth = 1;ctx.stroke();3. lineJoin = type同一个 path 内，设定线条与线条间接合处的样式。共有 3 个值 round, bevel 和 miter：round 通过填充一个额外的，圆心在相连部分末端的扇形，绘制拐角的形状。 圆角的半径是线段的宽度。bevel 在相连部分的末端填充一个额外的以三角形为底的区域， 每个部分都有各自独立的矩形拐角。miter(默认) 通过延伸相连部分的外边缘，使其相交于一点，形成一个额外的菱形区域。function draw(){ var canvas = document.getElementById('tutorial'); if (!canvas.getContext) return; var ctx = canvas.getContext("2d"); var lineJoin = ['round', 'bevel', 'miter']; ctx.lineWidth = 20; for (var i = 0; i lineJoin.length; i++){ ctx.lineJoin = lineJoin[i]; ctx.beginPath(); ctx.moveTo(50, 50 + i * 50); ctx.lineTo(100, 100 + i * 50); ctx.lineTo(150, 50 + i * 50); ctx.lineTo(200, 100 + i * 50); ctx.lineTo(250, 50 + i * 50); ctx.stroke(); } }draw();4. 虚线用 setLineDash 方法和 lineDashOffset 属性来制定虚线样式。 setLineDash 方法接受一个数组，来指定线段与间隙的交替；lineDashOffset属性设置起始偏移量。function draw(){ var canvas = document.getElementById('tutorial'); if (!canvas.getContext) return; var ctx = canvas.getContext("2d"); ctx.setLineDash([20, 5]); ctx.lineDashOffset = -0; ctx.strokeRect(50, 50, 210, 210);}draw();备注： getLineDash() 返回一个包含当前虚线样式，长度为非负偶数的数组。六、绘制文本绘制文本的两个方法canvas 提供了两种方法来渲染文本:fillText(text, x, y [, maxWidth]) 在指定的 (x,y) 位置填充指定的文本，绘制的最大宽度是可选的。strokeText(text, x, y [, maxWidth]) 在指定的 (x,y) 位置绘制文本边框，绘制的最大宽度是可选的。var ctx;function draw(){ var canvas = document.getElementById('tutorial'); if (!canvas.getContext) return; ctx = canvas.getContext("2d"); ctx.font = "100px sans-serif" ctx.fillText("天若有情", 10, 100); ctx.strokeText("天若有情", 10, 200)}draw();给文本添加样式font = value 当前我们用来绘制文本的样式。这个字符串使用和 CSS font 属性相同的语法。 默认的字体是 10px sans-serif。textAlign = value 文本对齐选项。 可选的值包括：start, end, left, right or center。 默认值是 start。textBaseline = value 基线对齐选项，可选的值包括：top, hanging, middle, alphabetic, ideographic, bottom。默认值是 alphabetic。。direction = value 文本方向。可能的值包括：ltr, rtl, inherit。默认值是 inherit。七、绘制图片​ 我们也可以在 canvas 上直接绘制图片。7.1 由零开始创建图片var img = new Image(); img.src = 'myImage.png'; 脚本执行后图片开始装载。绘制 img// 参数 1：要绘制的 img // 参数 2、3：绘制的 img 在 canvas 中的坐标ctx.drawImage(img,0,0); 注意：考虑到图片是从网络加载，如果 drawImage 的时候图片还没有完全加载完成，则什么都不做，个别浏览器会抛异常。所以我们应该保证在 img 绘制完成之后再 drawImage。var img = new Image(); img.onload = function(){ ctx.drawImage(img, 0, 0)}img.src = 'myImage.png'; 7.2 绘制 img 标签元素中的图片​img 可以 new 也可以来源于我们页面的 标签。img src="./美女.jpg" alt="" width="300">br>canvas id="tutorial" width="600" height="400">canvas>function draw(){ var canvas = document.getElementById('tutorial'); if (!canvas.getContext) return; var ctx = canvas.getContext("2d"); var img = document.querySelector("img"); ctx.drawImage(img, 0, 0);}document.querySelector("img").onclick = function (){ draw();}第一张图片就是页面中的 标签：7.3 缩放图片drawImage() 也可以再添加两个参数：drawImage(image, x, y, width, height)​这个方法多了 2 个参数：width 和 height，这两个参数用来控制 当像 canvas 画入时应该缩放的大小。ctx.drawImage(img, 0, 0, 400, 200)7.4 切片(slice)drawImage(image, sx, sy, sWidth, sHeight, dx, dy, dWidth, dHeight)第一个参数和其它的是相同的，都是一个图像或者另一个 canvas 的引用。其他 8 个参数：前 4 个是定义图像源的切片位置和大小，后 4 个则是定义切片的目标显示位置和大小。八、状态的保存和恢复Saving and restoring state 是绘制复杂图形时必不可少的操作。save() 和 restore()save 和 restore 方法是用来保存和恢复 canvas 状态的，都没有参数。​Canvas 的状态就是当前画面应用的所有样式和变形的一个快照。1、关于 save() ：Canvas状态存储在栈中，每当save()方法被调用后，当前的状态就被推送到栈中保存。一个绘画状态包括：当前应用的变形（即移动，旋转和缩放）strokeStyle, fillStyle, globalAlpha, lineWidth, lineCap, lineJoin, miterLimit, shadowOffsetX, shadowOffsetY, shadowBlur, shadowColor, globalCompositeOperation 的值当前的裁切路径（clipping path）​可以调用任意多次 save方法(类似数组的 push())。可以调用任意多次 save方法(类似数组的push())。2、关于restore()：每一次调用 restore 方法，上一个保存的状态就从栈中弹出，所有设定都恢复(类似数组的 pop())。var ctx;function draw(){ var canvas = document.getElementById('tutorial'); if (!canvas.getContext) return; var ctx = canvas.getContext("2d"); ctx.fillRect(0, 0, 150, 150); ctx.save(); ctx.fillStyle = 'red' ctx.fillRect(15, 15, 120, 120); ctx.save(); ctx.fillStyle = '#FFF' ctx.fillRect(30, 30, 90, 90); ctx.restore(); ctx.fillRect(45, 45, 60, 60); ctx.restore(); ctx.fillRect(60, 60, 30, 30); }draw();九、变形9.1 translatetranslate(x, y)用来移动 canvas 的原点到指定的位置​translate 方法接受两个参数。x 是左右偏移量，y 是上下偏移量，如右图所示。在做变形之前先保存状态是一个良好的习惯。大多数情况下，调用.

Well, there are a few things that set them apart! For one, while all of them have some blending, it's very straightforward blending because the colors you'll be blending with are very similar to each other, i.e., green and yellow or a darker and lighter version of the same color; this will help you a lot with getting your blending in with minimal stress about colors getting muddy! Another thing that makes these easier than others is that they are more natural subjects with little symmetry, making them more forgiving if you don't stay
