  • dynamically double image size

    - by Edan Duarte
    I have an embarrassingly simple question: How can I display an image at double its size without hard coding the width and height attributes? Here's what I tried, but I ended up having to just enter 1000 for width and height. Is something wrong with my function? Thanks! <img onload="double(self.id);" name="bigPic" id="bigPic" src="album1.jpg" height="1000" width="1000"/> function double(id) { var img = document.getElementById(id); var dblWdth = img.width * 2; var dblHt = img.height * 2; img.height = dblHt; img.width = dblWdth; }

  • g++ library search failure

    - by Frederick
    I have a directory structure as below: / | +--- /lib | libsomething.a | libsomething.so | +----/obj anObjFile.o When I run the following command from within the obj directory: g++ -L../lib -lsomething anObjFile.o I get undefined reference errors. Apparently gcc is failing to locate libsomething.a. But now if I delete libsomething.so and then rerun the command, linking succeeds. As per gcc documentation -lsomething should expand to libsomething.a. Then why is presence of libsomething.so causing the library search to fail? Also, how can I resolve this problem? I'm on Linux Mint 12 with gcc version 4.6.1.

  • centering image vertically in all resolutions

    - by gnomixa
    I need to be able to center the image vertically for all the common resolutions. A lot of ppl here on SO have already asked this question before, and 90% of then give this tutorial http://www.jakpsatweb.cz/css/css-vertical-center-solution.html as an answer. However, when viewed at my 1280 by 1024 res monitor in FF, it's not centered. And worse yet, it breaks horribly in IE7. So, it's definitely NOT the answer. Am I chasing the impossible dream? The solution has to work for FF and IE 6/7 the solution can be anything that would work, though being a bit of a purist, I would prefer a div over table:)

  • IE7 cutting off image

    - by Kimberley
    Hi all I have 3 divs with rollover images inside them stacked vertically inside my main content div. IE7 is chopping off about three quarters of the bottom div and I can't figure out why. It displays perfectly in all other browsers (even IE6) but IE7 just won't display properly. This is my first website so I still have a lot to learn. I've managed to fix the other IE bugs but just can't figure this one out. Any help appreciated! } .main_content { float: left; width: 816px; background-image: url(Images/evokedesign_bg_tile.png); background-repeat: repeat-y; overflow: hidden; } .portfolio_buttons { float: left; width: 634px;

    - by user1506841
    Using XCode, I am trying to figure out how to display a different image when someone clicks or presses down on one of my buttons before being taken to a second screen.

  • jQuery center image

    - by Aaron Moodie
    I've got an issue where I was tying to center images using the jQuery Cycle plugin. I found this solution, but it wasn't working on single images (there isn't always 2 images), so I wrote my own little bit of code, which seems to be working, except it sometimes doesn't subtract the height of the image from the height of the div, and so i end up with a margin of 310px. var $image_cnt = $("#images > img").size(); if($image_cnt < 2) { var $single_img = $("#images").children(':first-child'); var h = $single_img.height(); $single_img.css({ marginTop: (620 - h) / 2, }); $(".next").css("display","none"); $(".prev").css("display","none"); } I haven't used jQuery much, and just wanted to know if I'd missed something simple, or had written something wrong, which is why the marginTop wasn't playing nice.

  • Java: Send BufferedImage through Socket with a low bitdepth

    - by Martijn Courteaux
    Hi, The title says enough I think. I have a full quality BufferedImage and I want to send it through an OutputStream with a low bitdepth. I don't want an algorithm to change pixel by pixel the quality, so it is still a full-quality. So, the goal is to write the image (with the full resolution) through the OuputStream with a very small size. Thanks, Martijn

  • How does an unsharp mask work?

    - by Bob Aman
    I've been playing around with image processing lately, and I'd like to know how the unsharp mask algorithm works. I'm looking at the source code for Gimp and it's implementation, but so far I'm still in the dark about how it actually works. I need to implement it for a project I'm working on, but I'd like to actually understand the algorithm I'm using.
