Displaying Images Properly Maintaining Its Aspect Ratio?
Dec 22, 2009
displaying images properly maintaining its aspect ratio?
My requirement:
===========
I have a table with single cell (means single row and column). I have to display image inside this cell. But when I do so using the below mentioned statement, the image expands and cover the entire cell area.
Has anyone got any suggestions for keeping aspect ratio when scaling an image. I want to use it on my 'advert full details' on my website. This page displays an image the user has uploaded to my database, but sometimes I get really hugh images uploaded! When I scale them using % in Dreamweaver I lose the aspect ratio!
Is there a way to create a div or some container in which there will be an image such that the image fills the container but retains its aspect ratio? So if the container is 100px x 100px and an image is 200px x 100px it will be resized to 100px x 50px. Conversely, if the image is 100px x 200px then it resizes to 50px x 100px. An image of 400px x 50px becomes 100px x 12.5px and so forth.
The issue is I have to dynamically build the container pulling images from an image folder. The images can come in all sizes. But I want to make sure they all fit in the same square 'box' without distorting the image.
There is text and a button below the image and I want them to stay in the same 'spot' on the screen without being moved around because the height or width of the image above it grows/shrinks to accommodate a change in either the height or width. These can change but not outside a controlled 'box'.
Maybe there's a way to get the actual size (through Javascript or something) then calculate a percentage to resize the image to?
This slideshow works fine except that it keeps the aspect ratio of the original pic image. If original image is a portrate all photos are portrate size, even landscapes. If original is landscape, the same is true. The script works correctly when viewing in MS FrontPage. After FTP uploading problem appears. Code:
I am building a site in Dreamweaver for a client which uses templates for a photogallery that uses simple Javascript to load images "OnClick" into a named <img> tag. The <img> tag has no dimensions preset because the loaded images vary in size and aspect ratio (the images are all prepared so that they will fit easily within the rest of the page layout, using their actual dimensions).
This all works just fine on Firefox (Apple), but on Safari and Mac IE there is a problem. When image-2 replaces image-1 (using MM_swapimage), if image-2 has the same height but a narrower width than image-1, then image-2 appears with image-1's width. Both image-2 and image-1 have the same height, so the display of image-2 now has the wrong aspect ratio (everthing looks "fatter").
I haven't checked Windows browsers yet. I searched around and haven't seen a similar issue. Anyone know about this, and a good workaround?
so im almost finished my first site! very excited. its for my dads business, hes a screening contractor.actually i doubt he will get any business out of it, even once we get our real domain name and everything because i don't even know how to get Google to like it. its OK though, its mainly just a practice site for me anyways before i make a resume site for myself. anyways, this mayt sound like a flash question but i asked on flash sites and they have no idea, and i think it has more to do with how i embedded the flash. yoy see, it consists of 3 divs, an html content area, and a flash banner and a flash menu, which stretch depending on the window size to keep their aspect ratio. its that streachyness that i believe is causing the problem. everything works exactly as planned in Firefox, chrome, and pure flash player. but in IE, safari and opera, the size and position of things are way messed up! (only really care about IE). the edges of dynamic text are slightly to the left or right and hanging behind things because of it, same with some movie clips and when i didn't want things to appear on the stage i set their x position to be the length of the stage,
i think that ie is calculating the size onresize incorrectly. heres the site, take a look at the the script file:[URL]..
I've been working at this one for a few days now, and I keep getting the same puzzling results on what should probably have been a simple issue.
My page has images I've loaded at the top and set to {display: none}. The eventual goal is to create thumbnails that will maintain the original images' proportions, but fit within 150x150 px (this is for an artist's gallery page, so it's pretty important to keep the thumbnails looking like the originals). Obviously, the first thing I need to do is get the images' heights and widths. I've tried to do this by iterating through the document.images array and just getting the widths and heights, but for some reason I always get 0 x 0 for the first image. I've tried fixing this by inserting another image before it and then starting the loop at 1 instead of 0 (so it excludes that first image), but I still get the same value. I even tried setting the script to "defer" so it wouldn't run until the page had loaded. Same results. It also doesn't seem to matter whether I ask for document.images[x].width or document.images[x].naturalWidth. The same thing happens either way. Does anyone know what's going on? There's got to be something I'm missing.
where da boss wants our a large piece of our site to be fully dynamic and integrated on any screen size. This means changing font on size. Well I cam up with a solution, figured if no one has one better, then i'll share
i am working on a project that will involve displaying a long list of product information. this will include images and description of the product. knowing fully well that users must have uploaded images with different dimensions, i want to display the images such that they will all have same dimensions without having some of them lose aspect ratio. i want it to look like the way facebook displays facepile (your friends), it may only hide a portion of it,
I am seeking a easy to maintain and more importantly *working* way to pre-fetch images, so the pages I develop load smoothly without seeing the images kick in flicker as they usually do. Important - I need this to work on Internet Explorer 6.0+ and FireFox.
I am presently using at the head of the page,
pic100= new Image; pic100.src="./imageme.gif";
However, it doesn't seem to work on FireFox at all. I've tried different combinations with the URL path, but I don't know what I am doing wrong. Can someone please assist me with this boggle?
I have a lot of images on a page and the have to be a little bit larger, so i dont want to change all of the css.I have made a couple of lines of code which doesn't give the right values back.The images have all diffrent sizes.
$('.imgbox').each(function(){ var getX = $(this).width(); var getY = $(this).height();[code]....
there's probably some thing wrong because it gives me very big values back.
I have 3 images that I am trying to swap in and out with eachother. It starts off with the "Good Afternoon.gif" then I have a checkbox that changes it from and switches between the "Eyeball.jpg" and the "Smileys.gif" without going back to the "Good Afternoon.gif. That works perfectly fine and as intended. What does not work is my reset button, it unchecks the checkbox that I created as it should be does not set the image back to the "Good Afternoon.gif". I created goodAfternoon and a goodAfternoonFinal images because I am telling the code to to goodAfternoon.src=Eyeball.src; so I have the goodAfternoonFinal to change it back to the original pic.
I'm new to jquery and am experimenting with implementing it into my existing work. I've got the cycle plugin working pretty well, only the 'turnDown' transition I want to use only appears to work on images. All other transitions seem to work fine with both content and images. I've done loads of searches on this but can't find anything specifically related to this...
Below is a link to where I'm at with it - the first 2 transitions are images and work as expected, giving that 'squashed' look as they slide in and out. The next 2 are divs, with an image, heading, and a paragraph inside - they seem to just 'drop' out which has a completely different effect and not what I want [URL]. Is there something in the plugin code itself I can tweak to make this happen, or is this particular transition intended for just images?
I need help, HTML--i have two links, linkA & linkB--when clicking linkA -should display image1 and whn clicking linkB image2 should be displayed. The trick is they must be displayed in one image tag.
For the moment disregarding function thirdPic, I am able to click on "sample text" and I switch from an invisible image (actually 1 px by 1 px) with a picture of a book with a quote (firstPic) that I want to appear on screen. After reading the quote the reader can click on the image of the book and it will disappear. And it works fine. However, there are a couple of cases where I would like to show a lengthier quotation which would require me to click on the first book image(firstPic) and a second book image would appear with more text(thirdPic). I can get the second image to appear but I can't get it to disappear. Or I can get the first image to appear and get back to the empty screen but I want to do both. Everything I've tried to do doesn't work. I DO NOT WANT TO HAVE BUTTON TO CLICK THROUGH A SLIDESHOW. It would not be the representation I want ot produce.
Javascript Code ---------------------------------- function firstPic() { document.getElementById('blankPic2').src="../images/pic657.gif";
there I am using the below code to resize images posted on a forum, however when the page is loading it loads the images full size on sreen stretching the page to however wide the largest picture is and only resizes them once every picture has loaded and the page then goes back to normal width.oes anyone know how I could make it so the images only display once they've resized ?
<script> window.onload = resizeimg; function resizeimg()
Why this greybox isnt displaying my images? Click on the 'launch gallery' button at the bottom of the page: [URL]. I know all the paths are correct I just cant figure out why they wont display in the overlay!
When someone clicks on an image here (URL...), the rest of the images collapse and become invisible.Also, there will be a "show other images" button which will then show the rest of the images.
I need to display a set of images. NOT a slideshow that automatically changes, but a very simple display, one image at a time, that moves to next or previous by mouse click or arrow.
I can retrieve the set of filespecs in php with no problem. And I've got the setup in php to display the file, one at a time.
I"ve figured out how to open a full-screen window in javascript.
What I need (I started in php and they sent me over here for specific javascript info), is to put everything together...
1. I'd LIKE to automatically set the resolution on the system to 1024x768. I've been told html and javascript can't do that, so it'll have to be done by the user.
2. I figured out how to open a full-screen window in javascript.
3. What I need is to display the image from php and have it show up in the full-screen window I created. Then it just sits there until the user presses an arrow key (or hopefully something with the mouse) to go to the next (or previous) image. Back to php for the next file and display...
Once the last image in the set is displayed I'd like to have the window I created go away, sending me back to the screen from which all that got started...
So, as far as I know, the two things I need to know are how to display an image in a particular window from php. And, how to get mouse-clicks and/or arrow keys back to php so I can use them....
I'm creating a preview function that opens a new window, and then writes the values of the text fields, now my script is below, but I need to be able to make sure that the enters/breaks/carriage returns are kept when calling this page. The data I require to keep these breaks is an text area. Code:
I would like to add dynamic text sizing to a website. There will be three text sizes. When the default is used, only the "Increase text size" button is shown. When the maximum size is used, only the "Decrease text size" button is shown. And otherwise, both buttons are shown.
I've been working on a mockup as follows at the end, but my issue is that once I have manipulated an element of the HTML DOM, if I access it again to check it's value, I will only get the original value in the document. To do the dynamic buttons, I need to maintain some kind of state between function calls, so that I know what the current size is. Can I even do this with Javascript or am I barking up the wrong tree?
I've got a div with an id of messages - It is essentially a chat system however chat usually adds messages to the bottom of a list which means the messages do not get pushed down while you are reading them. This system instead adds the messages to the top. I need a way of finding the current scroll position so that when a new message is added the scroll remains in the same place.
i have a login area (user/pass text boxes). when the user submits the form, the page is reloaded with with a global php variable "loggedIn" set to true. i also store the username and password in the page in a hidden form -- so that it can be passed to other pages on the site through standard navigation (maintaining the "loggedIn" status). however, is there any way to save this information if the user hits refresh?
as it stands, whenever the user hits refresh, the user/pass data is lost, and loggedIn is set to false. can this be worked around without using cookies?
I am currently using multiple include files with my website and my issue is specifically with my navigation include. All I'm using is a simple unordered list with images for list items. Ofcourse each list item/link takes you to a another page. I have up, over, and down images for each menu list item. What I need to figure out is how to keep the associated menu item's down image active when taken to the associated page.I'm assuming it might entail some Javascript within the navigation include or per list item that tells the browser to keep the down image active when landing on a certain URL. I don't know what that code is.
