HTML 5 canvas Tag - Quackit Tutorials

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. I took a screen shot of the video and under the layer where the video pops up... I have an image pop up... so if the video doesn't show in the .htm in Canvas (which it won't...) I'm hoping the image/click box feature will show up and users can click on that to open the video as an external source. The only thing I don't like about doing that is if the video link is ever broken... then... they can't watch it. If the

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.

Line. Here is an example :Output : Line Cap var canvas = document.getElementById('DemoCanvas');if (canvas.getContext) { var context = canvas.getContext("2d"); // butt line cap (first line) context.beginPath(); context.moveTo(20,20); context.lineTo(20,200); context.lineWidth = 25; context.strokeStyle = '#ff0000'; context.lineCap = 'butt'; context.stroke(); // round line cap (second line) context.beginPath(); context.moveTo(80,20); context.lineTo(80,200); context.lineWidth = 25; context.strokeStyle = '#ff0000'; context.lineCap = 'round'; context.stroke(); // square line cap (third line) context.beginPath(); context.moveTo(120,20); context.lineTo(120,200); context.lineWidth = 25; context.strokeStyle = '#ff0000'; context.lineCap = 'square'; context.stroke();} Live Demo --> Line Join lineJoin property is used to get or set the type of corner that is created when two lines join. There are three values : bevel : A filled triangle connects the two lines that are joined, creating a beveled corner. round : Lines join with a rounded corner. square : Default. Lines join with a smoothly mitered corner. Here is an example : Output : Line Joining var canvas = document.getElementById('DemoCanvas');if (canvas.getContext) { var ctx = canvas.getContext("2d"); var lStart = 50; var lEnd = 200; var yStart = 20; ctx.beginPath(); ctx.lineWidth = 25;// Use a bevel corner. ctx.lineJoin = "bevel"; ctx.moveTo(50, 20); ctx.lineTo(150, 20); ctx.lineTo(150, 120); ctx.stroke();// Use a round corner. ctx.beginPath(); ctx.lineJoin = "round"; ctx.moveTo(50, 140); ctx.lineTo(150, 140); ctx.lineTo(150, 260); ctx.stroke();// Use a miter. ctx.beginPath(); ctx.lineJoin = "miter"; ctx.moveTo(50, 280); ctx.lineTo(150, 280); ctx.lineTo(150, 400); ctx.stroke(); } Live Demo --> See the Pen html css common editorby w3resource (@w3resource) on CodePen.

The Canvas element is a popular HTML 5 tag that can be embedded inside an HTML document for the purpose of drawing and displaying graphics. In this article, we will see how to use the HTML 5 canvas element in an ASP.NET Page to draw shapes and save them to an ASP.NET Image object.Let’s get started. Open Visual Studio 2010/2012 and create a blank ASP.NET Website. Now add a page ‘default.aspx’ to the site. Set it’s target schema for validation as HTML 5 by going to Tools > Options > Text Editor > HTML > Validation. If you do not see the HTML 5 option, make sure you have installed Visual Studio 2010 Service Pack 1and Web Standards Update for Microsoft Visual Studio 2010 SP1.Declare a HTML 5 canvas element of dimensions 400x400, add a Save button and an ASP.NET Image element to the form. We will draw some simple rectangles on this canvas using two functions – fillStyle and fillRectfillRect(float x, float y, float w, float h) – where x & y represent the upper-left corner of the rectangle and w & h represent the width and height of the rectangle you want.fillStyle = “rgba(R, G, B, V)” - we will fill color in this rectangle by using the fillStyle attribute. As you might have guessed, the RGB stand for red, green, and blue values (0–255) of the color you’re creating. ‘V’ represents the visibility factor 0 & 1, where 0 indicates invisibility, and 1 indicates visibility.To draw graphics on a Canvas, you require a JavaScript API that HTML 5 provides. We will be using jQuery to do our client script. Declare the following JavaScript code inside the element of your pagesrc=" $(function () { var canvas = document.getElementById('canasp'); var context = canvas.getContext('2d'); });Note: $(function(){} ensures that code is run only after the Canvas element is fully loaded by the browser. This is better than built-in Javascript event window.onload which has some quirks across browsers (FF/IE6/IE8/Opera) and waits for the entire page, including images to be loaded.We get a reference to the Canvas from the DOM by using getElementById (you can use jQuery code too, but I will stick to the old getElementById for now). We then ask the Canvas to give us a context to draw on. This is done by using the variable context that sets a reference to the 2D context of the canvas, which is used for all drawing purposes. We will now use the fillRect() and fillStyle() function to draw two rectangles. Add this code below the context codecontext.fillStyle = "rgba(156, 170, 193, 1)"; context.fillRect(30, 30, 70, 90); context.fillStyle = "rgba(0, 109, 141, 1)"; context.fillRect(10, 10, 70, 90);The code is pretty simple. We are

JSAPI support to import and export HTML templates for Canvas documents Following JSAPIs support import and export of HTML templates for canvas documents: Exports the HTML5 Canvas Publishing Template for given document,at the specified location: bool document::exportCanvasPublishTemplate(pathURI) Example: var pathURI ="file:///C|/Users/username/desktop/CanvasTemplate.html” var exportFlag =fl.getDocumentDOM().exportCanvasPublishTemplate(pathURI); if(!exportFlag) fl.trace(“Template could not be exported”); Imports and sets the HTML5 Canvas Publishing Template for given document, from the specified location pathURI: bool document::importCanvasPublishTemplate(pathURI) Example: var pathURI= “file:///C|/Users/username/desktop/CanvasTemplate.html”; var exportFlag =fl.getDocumentDOM().importCanvasPublishTemplate(pathURI); if(!exportFlag) fl.trace(“Template could not be imported”); Embed JavaScript into HTML Animate introduces the capability to include JS file within the HTML file during canvas publishing. In the Publish Settings menu, switch to Advanced tab and select Include JavaScript In HTML. Select OK in the Include JavaScript in HTML on Publish dialog box to republish the content overwriting HTML. This disables the Overwrite HTML file on Publish check box, and during any publishing event, HTML is generated, but overwritten. In the Select Stop including JavaScript in HTML, select OK to exclude the JavaScript and republish the HTML file. When the Overwrite HTML file on Publish is not selected, the Include JavaScript In HTML option is automatically disabled. If you do not want the HTML to be overwritten, the options Overwrite HTML file on Publish and Embed JS in HTML option cannot coexist. Adding Global and Third-party scripts Animators often utilize JavaScript code that is applicable to the entire animation. With this feature, you can add non-frame specific global and third-party scripts that can be applied to the whole animation from within Animate. To add and use global scripts: In the Actions panel, select Script within the Global hierarchy. The Global Script section allows you to write scripts applicable across documents either.
