Feb 23, 2010

I want to create a rectangle with a line in the middle with the canvas object. The problem is that the line in the middle gets bigger than the rest of the rectangle. How do I solve this? I believe it has something to do with shadows. If so, how do I turn them off.

How To Dynamically Create HTML 5 Canvas

Jun 19, 2011

Here's a snippet:
canvases[i] = document.createElement('canvas');
canvases[i].style.width = '3px';
canvases[i].style.height = '100%';
canvases[i].getContext("2D");
canvases[i].fillRect(1,0,1,table_height);

I'm trying to dynamically create a canvas element. Later in the script it gets attached to the DOM, and this works fine if the last two lines are missing. I end up with a canvas element that is 3px wide and 100% of the containing div tall. However, the last two lines make it crash, with the error report 'canvases[i].fillRect is not a function'.

If I change the last two lines to:
var drawing = canvases[i].getContext("2D");
drawing.fillRect(1,0,1,table_height);

It says 'drawing is null'. Something seems to be going wrong with the getContext bit, because setting the height and width work fine. It behaves the same if I append the canvas element to the DOM before trying to do the drawing as well. This is in FF4.0.1 with a xhtml1-strict.dtd doctype and valid html.

Script To Disable Arrow Button When Object Reaches The Canvas Edges?

Dec 13, 2011

I am using the HTML5 canvas element and an image object that I move around the canvas using the arrow buttons.I would like to be able to move the image around until it reaches the top, bottom, or sides of the canvas element. I know that I need to get the position of the x, y positions of the element. I'm just not sure about the logic to compare the elements location to the sides or top or bottom of the canvas. Furthermore, not sure how i would disable to arrow button to prevent me from arrowing the object outside of the canvas.I'm testing in IEMy canvas width is 512 and canvas height is 480The object I'm moving around is an image.png that is 32 X 32I know this isn't much to go on, but I'm having difficulty coming up with how to ask the question

CANVAS - Change Canvas Stroke On A Typeface Hover - Stroke() Doesn’t Work?

Mar 16, 2009

I have a menu in which is applied typeface script. Typeface 0.11 version doesn't support hover on links. There is an experimental version but doesn't work very well for me, so i tried to implement hover by myself.
Problem is: hover works pretty well changing canvas context property fillColor and then calling fill(), but the stroke on hovered voice remains on another color. Difficult to explain, so i put some test code online: TEST CODE As you can see, passing with mouse on the menu voices triggers the hover and the element change, but remains bordered in red.

Create A New Template Object That Inherits From The Built In Date Object

Oct 6, 2011

Is there any way at all to create a new template object that inherits from the built in Date object so as to be able to add new methods to that child object without adding them to the built in Date object? I've tried everything I can think of and as far as I can tell it keeps referencing the Date function instead of the Date object and so doesn't work.

I know for a fact that it is an object and I'm pretty sure that it isn't null. I will give you a link to the page that I'm troubleshooting even though it's embarrassingly ugly. Does anyone have
an idea of why it's not seeing the <select name=finish> on Line 183 in <Form Name="myform">?

Firefox/Netscape Rectangle Over Image

Aug 17, 2005

I have an application that draws a selection rectangle over a map
image. I can get it to work fine in IE and Opera, but not
Firefox/Netscape.

I've thrown the following small example together to illustrate the
problem - the problem being that FF/NE initially draw my rectangle
before the icon changes immediately to the black no-entry icon. Then,
when I let go of the mouse, the rectangle continues drawing, but it
doesn't stop as the mouseup has already fired of course.

IE was doing the same, but I found the ondragstart/cancelDragDrop
solution to that. I can't find what appears to be a similar solution
for FF/NE.....
