  • Debian-based image installation

    - by Michael
    Is there a preferred way to create root file-systems for Debian-based customized installations? We are currently going with multistrap but although it's better than hand-crafted chroot stuff, it still has a lot of edges and corners. Is there a more reliable and less error-prone way to produce a root filesystem of a Debian installation with some additional .debs installed? (I don't want to send out a Debian installer with a preseed file though.)

  • Resizing uploaded images based on a maximum width in django (PIL)

    - by AndrewE
    I'm working on a simple message board app in Django that lets people upload images to be displayed in their posts. Since the div containing the posts is only 700px, I want to resize the uploaded images to a max width of something like 680px to save space rather than using css to display an image that's too large within the space constraints. I've been searching this site, google and the PIL docs for a while and haven't found any way of resizing an image on one dimension while maintaining the original aspect ratio. Given my inexperience, it's possible that I'm just not recognizing a solution that's plain to someone who knows what to look for.

  • IE8 and below <input type="image"> value work around

    - by kielie
    Hi guys, I have a slight problem, I am trying to capture the input of two buttons, one yes, one no, into a database but for some reason the database doesn't always show the value of the button clicked, it just shows up blank. <form action="refer.php" method="post" id="formID" > <div class="prompt_container" style="float: left;"> <span class="prompt_item"><input type="image" src="images/yes.jpg" alt="submit" value="yes" onclick="this.disabled=true,this.form.submit();" /></span> <input type="hidden" name="refer" value="yes"> </div> </form> <form action="thank_you.php" method="post" id="formID" > <div class="prompt_container" style="float: right;"> <span class="prompt_item"><input type="image" src="images/no.jpg" alt="submit" value="no" onclick="this.disabled=true,this.form.submit();" /></span> <input type="hidden" name="refer" value="no" > </div> </form> Apparently anything lower than IE8 will ignore the value attribute of all form inputs. How could I get this to work properly in all browsers? jQuery or Javascript maybe?

  • Wordpress jQuery Post Attachment Image Gallery?

    - by LearnWebCode
    Hi everyone, Curious if any of you have a good solution for the following situation... because I've never thought of anything myself and usually have to resort to custom fields like "post-image-1" through "post-image-10" and manually paste the file name of a jpg in. Which is a horrible solution and only works for tech savvy posters. Basically I want non-tech savvy users to be able to upload / attach (but not insert into the actual post content) multiple images to a post, which will be turned into a makeshift gallery. Then I want to output these attachments in a list down the page after the post, using basic jQuery lightbox gallery functionality. It doesn't have to be through attachments, it could be a stand alone plugin, as long as it offers customizable markup. Basically any solution that would achieve the same thing would be incredible. Has anyone done this before? Am I missing something terribly obvious? I don't even know what exactly to call this, so I haven't had much luck with my Google research so far :( Thanks!

  • Upload image from URL to FTP server using PHP

  • Image Management System with Different Levels of Access

    - by Jason
    I work in the graphics department for a real estate brokerage, and we deal with a lot of photos. Agents take the photos, upload them to me, I touch up and standardize the photos, then I add them to an in-house server for future use by the graphics dept. I'd like to make the "sanitized" photo files available to the agents to use when they want, but I don't want the agents poking around the graphics department's files (things get misplaced, renamed and messed up in a hurry). What would be perfect is if we could create a read-only "mirror" (correct term?) of that server that could be accessed by the agents as needed, but which wouldn't feed back into our "sanitized" file system. Edit: I'm looking for an automatic solution... manually posting the files to two separate locations seems like an inelegant solution when working digitally. Edit: I'm trying to avoid any access barriers to the public (dirty) file system (however it's finally implemented). There are 40-50 real estate agents who need to access these files, half of whom can't reliably download an email attachment.

  • Image sprite not lining up in firefox

    - by Saif Bechan
    I am working with an image sprite to create my buttons. They work right in every browser except firefox. Lets say i have 2 spans next to eachother: <span class="spanleft"></span><span class="spanright"></span> and give them some styling(this is the actual code i use for the sprite) .spanleft{ background:url('/templates/default/img/auction/btn-toolbar.png') no-repeat 0 0; display:block; float:left; height:100px; width:13px; } .spanright{ background:url('/templates/default/img/auction/btn-toolbar.png') no-repeat 0 -104px; display:block; float:left; height:100px; width:30px; margin-left:0px; } Now this works in every browser i tested, the images line up great. But in firefox I get a small offset. Now i fiddled with the pixels a lot. Its not an offset of 1px, the offset is about 0.5 of a px. yeah. Ive made a screenshot of what i mean, and i'm going to put in the sprite for the buttons, they make lovely buttons, upstate,downstate,hover,disabled. You can use them in your projects. Here are the shots: This is the problem: Here is the image sprite: I hop this problem can be solved, i am working with FF 3.6. thanks guys!

  • What if Web page's background matters

    - by hgulyan
    Hi, I have a complex background image and images, that should be on exact positions of the background image. How can I organize web page? I can't use absolute positions, because I need to organize background to view it nice on any monitor, any resolution and any browser. It can be aligned to center or smth else. Web page can be written just with HTML, Javascript or with a library like JQuery. Here's an example of what kind of web page I'd like to have. http://desandro.com/portfolio/ (background picture and points on it) Thanks in advance.

  • Image resizing efficiency in C# and .NET 3.5

    - by Matthew Nichols
    I have written a web service to resize user uploaded images and all works correctly from a functional point of view, but it causes CPU usage to spike every time it is used. It is running on Windows Server 2008 64 bit. I have tried compiling to 32 and 64 bit and get about the same results. The heart of the service is this function: private Image CreateReducedImage(Image imgOrig, Size NewSize) { var newBM = new Bitmap(NewSize.Width, NewSize.Height); using (var newGrapics = Graphics.FromImage(newBM)) { newGrapics.CompositingQuality = CompositingQuality.HighSpeed; newGrapics.SmoothingMode = SmoothingMode.HighSpeed; newGrapics.InterpolationMode = InterpolationMode.HighQualityBicubic; newGrapics.DrawImage(imgOrig, new Rectangle(0, 0, NewSize.Width, NewSize.Height)); } return newBM; } I put a profiler on the service and it seemed to indicate the vast majority of the time is spent in the GDI+ library itself and there is not much to be gained in my code. Questions: Am I doing something glaringly inefficient in my code here? It seems to conform to the example I have seen. Are there gains to be had in using libraries other than GDI+? The benchmarks I have seen seem to indicate that GDI+ does well compare to other libraries but I didn't find enough of these to be confident. Are there gains to be had by using "unsafe code" blocks? Please let me know if I have not included enough of the code...I am happy to put as much up as requested but don't want to be obnoxious in the post.

  • Is there a way to force CoreImage to use the GPU?

    - by NSSplendid
    We are having the following problem: a series of Core Image filters runs constantly in our program. When evaluating on my Macbook Pro, Core Image decides to schedule all graphics computation on the GPU, as expected. When using a MacPro, however, CI uses the CPUs! This is a problem, as we need them for other processing. [1] The question now is: Can one tell CI to run exclusively on the GPU? [1] Both hardware sets are of the newest kind. The MacPro has 8 Cores.

  • Android: how to convert whole ImageView to Bitmap?

    - by yosh
    I have my application that is displaying images with different ratio, resized inside (centerInside) imageView. What I need is to create bitmap from the ImageView including the background (black in this case). So for example I have device screen 320x480, full screen imageView with image resized to 280x480. How could I get 320x480 bitmap from it? On top of this imageview I have some logos or buttons that I don't want to include to bitmap, they're like on top layer. All I need is bitmap with image and black border from some sides.

  • jquery .animate - image gets cropped during animation

    - by stef
    Hello all, I am currently programming a carousel with javascript using the jquery library. Basically, there are three images shown, the central image being bigger than the two others. Upon going left or right, the central images is resized from 115px*115px to 50px*50px and tossed left or right, depending on the user input. The problem is that when the resize happens, the central image gets gradually cropped until it reaches the 50px*50px and then return to a more normal state: http://www.filedropper.com/imggetscropped Javascript is as follow: $("div#carousel .item:eq(2)").animate({'width':'50px', 'height':'50px', 'opacity':'0.5'}, {queue:false, duration:900}); $("div#carousel .item:eq(2) img").animate({'width':'50px', 'height':'50px', 'marginTop': '30px'}, {queue:false, duration:900}); $("div#carousel .item:eq(1)").animate({'width':'115px', 'height':'115px', 'opacity':'1'}, {queue:false, duration:900}); $("div#carousel .item:eq(1) img").animate({'width':'115px', 'height':'115px', 'marginTop': '0px'}, {queue:false, duration:900}); $("div#carousel .item:not(eq(2))").animate({'left':'+=56px'}, {queue:false, duration:900}); $("div#carousel .item:eq(2)").animate({'left':'+=122px'}, {queue:false, duration:900, complete: carousel.toggleInput}); Images used are png with transparency.

  • Getting imagename and make link from <img> with jQuery

    - by Bulan
    With jQuery, I want to make all images under a specific path on a site clickable and showing a big image using Fancybox, which is a lighbox variant plugin for jQuery. My small images are located under "images/products/small", the big ones under "images/products/big" and the imagename is always the same The page is showing the image with the following code: <img src="images/products/small/hat.jpg" alt="Nice hat"> What i want is some jQuery script that makes this into: <a href="images/products/big/hat.jpg" class="fancybox"><img src="images/products/small/hat.jpg" alt="Nice hat"></a> Maybe the part with setting class on the link tag can be skipped and just activate fancybox on the element directly with $(elm).fancybox(); I was looking around a bit and it looks like the jQuery functions "attr" and "wrap" might be useful, but with my currently limited jQuery skills I can't really connect the dots.

  • Checking for multiple images loaded

    - by Stanni
    Hi, I'm using the canvas feature of html5. I've got some images to draw on the canvas and I need to check that they have all loaded before I can use them. I have declared them inside an array, I need a way of checking if they have all loaded at the same time but I am not sure how to do this. Here is my code: var color = new Array(); color[0] = new Image(); color[0].src = "green.png"; color[1] = new Image(); color[1].src = "blue.png"; Currently to check if the images have loaded, I would have to do it one by one like so: color[0].onload = function(){ //code here } color[1].onload = function(){ //code here } If I had a lot more images, Which I will later in in development, This would be a really inefficient way of checking them all. How would I check them all at the same time?

  • Image error with wordpress and php

    - by bubdada
    It may seem stupid question, but i've a serious problem... if you could check out orcik.net the thumbnail images does not appear. I figured out the reason but I don't know how to solve.. http://orcik.net/projects/thumb/orcikthumb.php?src=http://orcik.net/wp-content/uploads/2010/05/mac-safari-search-cache.png If you go to the above link you will get page not found error. However, if you go to the link below you'll get the thumbnail version of the image... http://orcik.net/projects/thumb/orcikthumb.php?src=/wp-content/uploads/2010/05/mac-safari-search-cache.png I'm using this piece of code on wordpress and the line appears like <a href="<?php the_permalink() ?>" rel="bookmark"> <img src="<?php bloginfo('template_directory'); ?>/includes/orcikthumb.php?src=<?php get_thumbnail($post->ID, 'full'); ?>&amp;h=<?php echo get_theme_mod($height); ?>&amp;w=<?php echo get_theme_mod($width); ?>&amp;zc=1" alt="<?php the_title(); ?>" /> </a> Thus, I believe I can't change the directory of image. But I could not figure out why I am getting page not found error. Is that might be CHMOD'es??? or something else?? Thanks

  • How to extract images from flash viewers?

    - by RC
    This deals with the (diverse) flash viewers that let you zoom in on images on websites. I’m trying to extract the large, zoomed-in image rendered by the viewer. In many cases the images seem to be dynamically called by the viewer, or are created only for the part of the image you are zooming on at that point. Ideally, the approach here would be a programmatic one that could be called on an identified flash element. Expect there is nothing universal, but interested in the top few approaches that will grab most cases.

  • Is there an HTML code that can make my background picture transparent and my text non-transparent?

    - by user1831312
    Okay so I've been typing some HTML code for a technology class that I need to satisfy for my Education major. This is what i have for my background: body { background-image:url('islandbeach.jpg'); background-repeat:repeat; background-position:center; background-attachment:fixed; background-size:cover; } Now, I want to make my background transparent or faded so I can see the text and the other image that I have. The background is too colorful to be able to see the words without having to squint. Are there any HTML codes that can do this for me? I am not a pro at this stuff, I've just been following everything my professor has told me to do so please explain stuff in baby steps if you do have an answer. Thank you so so much!

  • Does the '#' modifier for cropping images in Paperclip work only for square images?

    - by user3451384
    It is very well documented that you can create square thumbnails with center cropping with Paperclip (4) and Rails (4). I would like to have an image of very specific dimensions (e.g. 200x100) and if input an image of let's say 800x200 it is first resized to 400x100 and then the width (400) is cropped down to 200 pixel from the center (i.e. 100px cut from the right and 100 px cut from the left). I tried with 200x100# and it does not appear to work (i.e. the '#' has no effect). I have found that I could adapt other solutions such as this, but I was wondering if '#' is supposed to work only for cropping to square images, or is a Paperclip bug or I am doing something wrong...
