HTML - Using Canvas To Create A Horizontal Line??
Hello all,
I am trying to replicate a style I have seen on the site listed below, where they appear to be using the CANVAS command to create a gradient top and bottom margin. I can seem to find anything online about how to do this but obviously they have figured it out. http://www.xtrememac.com/ Any ideas or pointing me in the right direction are greatly appreciated. Thanks! Similar TutorialsI have found what seems to be a rather big problem in the HTML canvas When drawing circles, and I presume all shapes, the size of the circle is different based on whether one is filling it, or sketching it. If we have a circle of radius 10 and line width k, and we decide to fill it, that line width will be evenly dispersed about the perimeter of the circle such that half the line width is inside the circle, and half is outside the circle. If, however, the same circle is sketched, the line width will still be the same, but it will now be dispersed entirely on the outside of the circle, thus making it larger. If I am wrong, and this is how figures are supposed to be drawn, or if I am simply not using the right settings, please let me know =) Hi: I'm a newbie and am designing my 1st screen using Transistional HTML. Without using CSS, is there a simple way to draw a horizontal line across the screen ? TIA -Mel Smith Hi: I'm laying out a 7-col table with only vertical borders between the columns (i.e., rules="cols"). This shows correctly. However, after every 'n' rows or so, I wish to have a horizontal line across all seven columns of the table. Although I am a 'basic' CSS user (very basic), in this table I want to use 'plain vanilla' html or xhtml for this 'horizontal line' or border across the width of the table Thanks for any hints ! -Mel Smith -Mesa, Arizona I am trying to display a horizontal line using CSS and the results are fine when viewed with Mozilla Firefox 2.0, but not in IE6. I am not able to control the line height in IE6. In the test code below, I also included the deprecated properties code which works fine in both browsers. Any help to switching to CSS is greatly appreciated. ineuw <html> <head> <style type="text/css"> div.hr { background-color: #ff0080; border: 0px; clear: left; color: #ff0080; float: left; height: 5px; margin: 4px 0px 4px 0px; width: 100%; } </style> </head> <body> <br> <br> <!-- deprecated mode works fine in both Firefox and IE --> deprecated display <div><hr size="5" color="#ff0080" bgcolor="#ff0080" width="100%"></div> <br> <br> <!-- line-height of 5px in the css has no effect in IE --> css display <div class="hr"></div> </body> </html> Hello all, The team I work on is going to be creating a .NET application which reads organization information from a database and creates a dynamic Org Chart. One of common features in an org chart is lines that show reporting structures. Does anyone have any recommendations on how we could dynamically create such lines that would need to go both horizontally and vertically? Thanks I've seen on some sites that images show up within a block and they scroll left and right when user clicks a button. And many times, these are not flash files, but html, or xhtml or dhtml or asp or php or some other extensions. I am trying to create a database of images all with labels (multiple), so that I can pull all images of a label to a window and have them scroll right and left with buttons. does anyone here know how this may be done? Thanks Navs i have to draw ball on canvas in html 5 depending on the input given by user in a textbox. ex: if a user enter 5 in a textfield, 5 ball should draw on canvas. Hey guys, I'm having trouble typing in Canvas. I tried combining the jquery keyboard (http://net.tutsplus.com/tutorials/ja...ss-and-jquery/) with the canvas in order to directly type on the canvas, but I'm having trouble doing so. Does anyone have any suggestions? I really appreciate any help you can give me!

I'm a 3d (technical) artist, but my HTML knowledge is minimal. What I have is: - A PNG image without alpha to be used as the background. - One or more PNG's with alpha to be composited on top of this background using the embedded alpha channels. I want to do this using the Canvas element and what I learned from searching the web is they often composite everything offscreen and then draw it to the Canvas. So if anyone could provide me with small example I would be eternally grateful. It's mainly the syntax that stumps me right now. Thanks in advance. I'm drawing text on the screen (mouse coordinates) in this example: http://www.hindbrain.net/ex5.php In order to not have new text overlay old text and become unreadable, I have to clear a background rectangle and then draw the new text. Is there a way to clear the background rectangle so that it is not white or any solid color? Ie, is there a way to just clear it so that the original blue background is still there? thanks, William I'm an intermediate PS user/css coder/etc but I haven't had to design many sites from the ground up. With that said, I now have to design a web site that will work for the 800x600 crowd. What canvas size do I use in Photoshop to work with? Also, what would be the canvas size to use designing for 1024x768 screen resolutions? Thanks. Alright, well I'm needing to resize an image. Not a scaled version, but a 'cropped' version. Like it's called canvas resize in photoshop ect. I hope someone knows what I'm talking about lol Is this possible? I'd like to draw a screen using the canvas methods and then overlay html hyperlinks on this (fullscreen) canvas. I have experimented with capturing the mouse click event and know where I clicked on the canvas, but now I'd just like to be able to hyperlink to places right from the canvas. It would be convenient if you could somehow embed hrefs there. thanks, William Hello, hopefully i can find help here I want to save my canvas-content to a single image-file. There are an approach using todataurl(), which works fine. But not if i draw an image-file (e.g. car.jpg or house.png) to the canvas additionally. It does not return the whole image? Here I have my simple example-code: <head> <script> window.onload = function() { var canvas = document.getElementById("theCanvas"); var context = canvas.getContext("2d"); context.fillStyle = "navy"; context.fillRect(0,0,20,20); var imagefile = new Image(); imagefile.onload = function () { context.drawImage(imagefile, 22, 0,60,60); } imagefile.src = "http://www.sign-arts.de/joomla/images/stories/print_proj/mediclin/icon1.gif"; window.open(canvas.toDataURL('image/png')); }; </script> </head> <body id="bodi"> <canvas id="theCanvas" width="500" height="200" > </canvas> </body> Only the HTML5-methods like fillRect() are rendered to the new window, why this is so? What im doing wrong? Thanx in advance for help bilinok I need to go to the experts here , what I need to do is the following. I have an Adobe Edge animation, I need to take that animation along with a JQuery dropdown menu and put both on one html page. I have basic html knowledge to the point where the edge animation is saved as an html page ( edge automatically does this which includes all the Javascript files separately) So far I'm able to take the edge <div> and ad it to any html page as long as I copy the scripts to the head of that page. The trouble I'm having is adding the JQuery dropdown. It would be impossible for anyone reading this to know EXACTLY wht I mean without seeing the code, I do not want to add abunch of it or add a link to the files until someone replies and can actually look. any help? RD Greetings Folks! So I put this site together based on a website's site layout and well, let's just say is not as nice. I did, tho, do the best I could without using jquery scrollpane which the original site looks like they used. Here's the site I did http://www.universalpartnership.org I'd like to be able to make the page jumps smoother and have the particular sections come to the center rather than somewhere on the page. I'd really, really like to make the vertical scrolling on the whole page go away, it's seriously annoying. And is there a way to change the scroll bar to be smaller? Also, (hehehe) I had to add a table with nothing in it to get the width to be nice and big. I couldnt figure out how to increase the width POST starting the page and all. It'd be nice to dump that and do it the right way. I would have kept the table but I could get it to be flush against the top and the left. I guess the major issues I have is being able to add code post building the page in design view. I just dunno where things go and I've been reading article after article and it's been a lost cause so far. So, if you are kind and so inclined to offer some support by way of help, indicating where code goes would be awesome and a great learning curve for me! I've added the page as an attachment in case any whizzes can hook it up! thanks much in advance! peace rooster Hi everyone, http://www.eveningtweed.com/laura At the above site, I've got a div called 'work' which needs to contain a long line of images which I want users to horizontally scroll through using the DIV scrollbar. I've looked through countless forum posts and solutions on Google but nothing works. Can anyone tell me why this won't scroll horizontally and how to achieve it? Current CSS for the DIV: Code: .work {
border:0px;
height:350px;
overflow-x:scroll;
overflow-y:hidden;
width:100%;
}
Thanks in advance, Jez. I dont know how to explain it better but how do i do this http://www.target.com/Movies-MMB/b/r...ode=1259488011 so at the bottom of my page i can add 4 to 5 different products and allow for those left and right buttons show more... any direction would help thanks Can't tell you how many hours I've spent trying to do this, but it's a lot! An example page with the issue can be found here.. http://www.funkimunkibadges.co.uk/geekybadges-c-79.html I'm basically trying to change it to be a horizontal scroll instead of vertical. Top image here is what happens when I expand the data in the central box. The lower image is when is as it is now.. http://www.flickr.com/photos/creepyd/5710648997/ I'm not really sure where the problem lies, my guess is the html. The piece of CSS which creates the vertical scrollbar is here.. Code: #indexProductList.centerColumn {
width: 630px ;
height: 680px !important; /*CENTER SCROLLBAR HEIGHT*/
overflow:auto;
padding:0px;
If I change the 'auto' above to 'hidden', the scrollbar goes away, so it's definitely that controlling it. The php which creates the 5 columns is here.. If I change it to + 0.5, the last one will wrap to the next line, and not create a horizontal scrollbar. However if I change it so each column is more than 100%, I get a horizontal scrollbar?! Code: $col_width = floor(100/PRODUCT_LISTING_COLUMNS_PER_ROW) - 0.5; Thanks so much for any help. Here's the html for the central table with the normal vertical scrollbar in place.. HTML Code: <td valign="top">
