• Creating transparent PNG with exact RGBA values

  - by rrowland

  I'm color-coding a transparent image to be read programatically. However, the image seems to be getting compressed and my code is reading color values other than the ones I mean to pass it. Concept This is the output I get, exporting as PNG-24. I programatically check each pixel for one of the six colors I use in creating the image: 0x00000F 0x0000F0 0x000F00 0x00F000 0x0F0000 0xF00000 Each color represents a different texture to apply. Top right (0x00000F) will pull texture from the tile to its top right and blend it at a ratio equal to the opacity of the pixel. The end goal is to create a hex tiled grid with differing textures that blend smoothly. What's happening It seems that when converting to PNG, Photoshop will change the RGBA to make it smoother, or just to help compression size. Parts that should be 250 red range anywhere from 150 to 255. Question Whether using PNG or another web-compatible format, I need to be able to save these pixel values, essentially instructions, loss-less and still maintain transparency. Is this possible in any format or will I need to re-think my approach?

• How to convert or burn a .DMG image file on Windows?

  - by Nick Josevski

  Does anyone have software they use frequently and can recommend to burn a mac created .DMG file on a windows operating system? Ideally free, or at least reasonably priced. Or an alternative application convert it to .ISO or something equivalent. I'm looking for reassurance I won't be wasting several (more expensive than normal DVDs) dual layer DVDs to get this done right. As the .DMG file is 7gig.

• Image compression and thumbnail creation for PHP

  - by Saif Bechan

  I need some PHP classes that deal with image processing in a good manner. I have made a thumbnail creator myself but the end result quality is just horrible. Is it also possible to let PHP convert and save all images to one type. For example take an image(jpg,png,gif), compress it, resize it, and save as png. Can anyone recommend some good classes for this.

• Make a Drive Image Using an Ubuntu Live CD

  - by Trevor Bekolay

  Cloning a hard drive is useful, but what if you have to make several copies, or you just want to make a complete backup of a hard drive? Drive images let you put everything, and we mean everything, from your hard drive in one big file. With an Ubuntu Live CD, this is a simple process – the versatile tool dd can do this for us right out of the box. We’ve used dd to clone a hard drive before. Making a drive image is very similar, except instead of copying data from one hard drive to another, we copy from a hard drive to a file. Drive images are more flexible, as you can do what you please with the data once you’ve pulled it off the source drive. Your drive image is going to be a big file, depending on the size of your source drive – dd will copy every bit of it, even if there’s only one tiny file stored on the whole hard drive. So, to start, make sure you have a device connected to your computer that will be large enough to hold the drive image. Some ideas for places to store the drive image, and how to connect to them in an Ubuntu Live CD, can be found at this previous Live CD article. In this article, we’re going to make an image of a 1GB drive, and store it on another hard drive in the same PC. Note: always be cautious when using dd, as it’s very easy to completely wipe out a drive, as we will show later in this article. Creating a Drive Image Boot up into the Ubuntu Live CD environment. Since we’re going to store the drive image on a local hard drive, we first have to mount it. Click on Places and then the location that you want to store the image on – in our case, a 136GB internal drive. Open a terminal window (Applications > Accessories > Terminal) and navigate to the newly mounted drive. All mounted drives should be in /media, so we’ll use the command cd /media and then type the first few letters of our difficult-to-type drive, press tab to auto-complete the name, and switch to that directory. If you wish to place the drive image in a specific folder, then navigate to it now. We’ll just place our drive image in the root of our mounted drive. The next step is to determine the identifier for the drive you want to make an image of. In the terminal window, type in the command sudo fdisk -l Our 1GB drive is /dev/sda, so we make a note of that. Now we’ll use dd to make the image. The invocation is sudo dd if=/dev/sda of=./OldHD.img This means that we want to copy from the input file (“if”) /dev/sda (our source drive) to the output file (“of”) OldHD.img, which is located in the current working directory (that’s the “.” portion of the “of” string). It takes some time, but our image has been created…Let’s test to make sure it works. Drive Image Testing: Wiping the Drive Another interesting thing that dd can do is totally wipe out the data on a drive (a process we’ve covered before). The command for that is sudo dd if=/dev/urandom of=/dev/sda This takes some random data as input, and outputs it to our drive, /dev/sda. If we examine the drive now using sudo fdisk –l, we can see that the drive is, indeed, wiped. Drive Image Testing: Restoring the Drive Image We can restore our drive image with a call to dd that’s very similar to how we created the image. The only difference is that the image is going to be out input file, and the drive now our output file. The exact invocation is sudo dd if=./OldHD.img of=/dev/sda It takes a while, but when it’s finished, we can confirm with sudo fdisk –l that our drive is back to the way it used to be! Conclusion There are a lots of reasons to create a drive image, with backup being the most obvious. Fortunately, with dd creating a drive image only takes one line in a terminal window – if you’ve got an Ubuntu Live CD handy!

• Drupal Background Image as Block or Node

  - by Marcy Sutton

  Hi There. I am having trouble wrapping my head around how to make editable background images in my custom Drupal 6 theme. My client wants to have a different background image for each main section (which use multiple content types: page, blog, image gallery)... I am wondering, is there a way to make a custom content type into a dynamic background image block? I am using the Image, Image Cache, Views, CCK, Image Assist, Panels, Filefield, and Imagefield modules. What I'd like to do is add a background image field to various content types that allows a user to reference an image from the content library or upload a new image (similar to ImageAssist), and have it apply to a region in my template. Any suggestions on the best approach for this? Thank you!

• How do I convert a Linux disk image into a sparse file?

  - by endolith

  I have a bunch of disk images, made with ddrescue, on an EXT partition, and I want to reduce their size without losing data, while still being mountable. How can I fill the empty space in the image's filesystem with zeros, and then convert the file into a sparse file so this empty space is not actually stored on disk? For example: > du -s --si --apparent-size Jimage.image 120G Jimage.image > du -s --si Jimage.image 121G Jimage.image This actually only has 50G of real data on it, though, so the second measurement should be much smaller. This supposedly will fill empty space with zeros: cat /dev/zero > zero.file rm zero.file But if sparse files are handled transparently, it might actually create a sparse file without writing anything to the virtual disk, ironically preventing me from turning the virtual disk image into a sparse file itself. :) Does it? Note: For some reason, sudo dd if=/dev/zero of=./zero.file works when cat does not on a mounted disk image.

• Powerpoint template image placeholders can't send to back

  - by Marcus

  We want to be able to set up a PowerPoint 2007 template with a picture frame image. We then want to insert an image in normal view which would appear behind the picture frame image that was put in the template (so it looks logically like a picture in a picture frame). Problem is, when we insert the image in normal view it always appears on top of the picture frame image. It appears that you can't send to back when the other elements are included in a template. Any ideas?

• Scanned JPEGs are large and slow to load - can they be optimized losslessly?

  - by Alistair Knock

  I have hundreds of JPEG photographs which were scanned about 5 years ago from negative using a Konica Minolta DiMAGE Scan Dual IV. The dimensions are ~4500x3000, and the filesize is around 12Mb, compared to shots from a DSLR with dimensions of 3000x2300 and filesize of 2-4Mb (actually, these are the output from a RAW convertor). The filesize is obviously quite a big difference, but the issue that's bothering me is that the (perceived) loading time is at least 10 times slower. Is this size/speed discrepancy likely to be because the scanner software saved the JPEGs inefficiently / using an old compression format, or is it simply that the scanned negatives contain much more "detail" (in the form of grain/noise) than the digital images? If the former, is there a way to losslessly optimize them? I've tried re-exporting the scanned files to full size JPEG from my RAW software but the filesize is pretty much the same. Both files will have been saved at 100 quality.

• Resizing image algorithm in python

  - by hippocampus

  So, I'm learning my self python by this tutorial and I'm stuck with exercise number 13 which says: Write a function to uniformly shrink or enlarge an image. Your function should take an image along with a scaling factor. To shrink the image the scale factor should be between 0 and 1 to enlarge the image the scaling factor should be greater than 1. This is not meant as a question about PIL, but to ask which algorithm to use so I can code it myself. I've found some similar questions like this, but I dunno how to translate this into python. Any help would be appreciated. I've come to this: import image win = image.ImageWin() img = image.Image("cy.png") factor = 2 W = img.getWidth() H = img.getHeight() newW = int(W*factor) newH = int(H*factor) newImage = image.EmptyImage(newW, newH) for col in range(newW): for row in range(newH): p = img.getPixel(col,row) newImage.setPixel(col*factor,row*factor,p) newImage.draw(win) win.exitonclick() I should do this in a function, but this doesn't matter right now. Arguments for function would be (image, factor). You can try it on OP tutorial in ActiveCode. It makes a stretched image with empty columns :.

• Wait until image loads before performing function

  - by Steven

  I'm trying to create a simple portfolio page. I have a list of thumbs and an image. When you click on a thumb, the image will change. When a thumbnail is clicked, I'd like to have the image fade out, wait until the image is loaded, then fade back in. The problem I have right now is that some of the images are pretty big, so it fades out, then fades back in immediately, sometimes while the image is still loading. I'd like to avoid using setTimeout, since sometimes an image will load faster or slower than the time I set. Here's my code: $(function() { $('img#image').attr("src", $('ul#thumbs li:first img').attr("src")); $('ul#thumbs li img').click(function() { $('img#image').fadeOut(700); var src = $(this).attr("src"); $('img#image').attr("src", src); $('img#image').fadeIn(700); }); }); <img id="image" src="" alt="" /> <ul id="thumbs"> <li><img src="/images/thumb1.png" /></li> <li><img src="/images/thumb2.png" /></li> <li><img src="/images/thumb3.png" /></li> </ul>

• Mac disk images: any real difference between 'master' and 'compressed'?

  - by Rabarberski

  When creating a disk image (.cdr or .dmg) from a physical CD or DVD on Mac (using Disk Utility New Image) one can choose between 'CD\DVD Master‘ and 'compressed'. Apart from the obvious fact that a compressed image will be smaller, are there other differences? Will a compressed image for example not expand to an exact copy of the CD or DVD?

• bmp image header doubts

  - by vikramtheone

  Hi Guys, I'm doing a project where I have to make use of the pixel information of a bmp image. So, I'm gathering the image information by reading the header information of the input .bmp image. I'm quite successful with everything but one thing bothers me, can any one here clarify it? The header information of my .bmp image is as follows (My test image is very tiny and gray scale)- BMP File header File size 1210 Offset information 1078 BMP Information header Image Header Size 40 Image Size 132 Image width 9 Image height 11 Image bits_p_p 8 So, from the .bmp header I see that the image size is 132 (bytes) but when I multiply the width and height it is only 99, how is such a thing possible? I'm confident with 132 bytes because when I subtract the Offset value with the File Size value, I get 132(1210 - 1078 = 132) and also when I manually count the number of bytes (In a HEX editor) from the point 1078 or 436h (End of the offset field), there are exactly 132 bytes of pixel information. So, why is there a disparity between the size filed and the (width x height)? My future implementations are dependent on the image width and height information and not on Image size information. So, I have to understand thoroughly whats going on here. My understanding of the header should be clearly wrong... I guess!!! Help!!! Regards Vikram My bmp structures are a as follows - typedef struct bmpfile_magic { short magic; }BMP_MAGIC_NUMBER; typedef struct bmpfile_header { uint32_t filesz; uint16_t creator1; uint16_t creator2; uint32_t bmp_offset; }BMP_FILE_HEADER; typedef struct { uint32_t header_sz; uint32_t width; uint32_t height; uint16_t nplanes; uint16_t bitspp; uint32_t compress_type; uint32_t bmp_bytesz; uint32_t hres; uint32_t vres; uint32_t ncolors; uint32_t nimpcolors; } BMP_INFO_HEADER;

• use jQuery to get 'true size' of image without removing the class

  - by jon3laze

  I am using Jcrop on an image that is resized with css for uniformity. JS <script type="text/javascript"> $(window).load(function() { //invoke Jcrop API and set options var api = $.Jcrop('#image', { onSelect: storeCoords, trueSize: [w, h] }); api.disable(); //disable until ready to use //enable the Jcrop on crop button click $('#crop').click(function() { api.enable(); }); }); function storeCoords(c) { $('#X').val(c.x); $('#Y').val(c.y); $('#W').val(c.w); $('#H').val(c.h); }; </script> HTML <body> <img src="/path/to/image.jpg" id="image" class="img_class" alt="" /> <br /> <span id="crop" class="button">Crop Photo</span> <span id="#X" class="hidden"></span> <span id="#Y" class="hidden"></span> <span id="#W" class="hidden"></span> <span id="#H" class="hidden"></span> </body> CSS body { font-size: 13px; width: 500px; height: 500px; } .image { width: 200px; height: 300px; } .hidden { display: none; } I need to set the h and w variables to the size of the actual image. I tried using the .clone() manipulator to make a copy of the image and then remove the class from the clone to get the sizing but it sets the variables to zeros. var pic = $('#image').clone(); pic.removeClass('image'); var h = pic.height(); var w = pic.width(); It works if I append the image to an element in the page, but these are larger images and I would prefer not to be loading them as hidden images if there is a better way to do this. Also removing the class, setting the variables, and then re-adding the class was producing sporadic results. I was hoping for something along the lines of: $('#image').removeClass('image', function() { h = $(this).height(); w = $(this).width(); }).addClass('image'); But the removeClass function doesn't work like that :P

• Does ZFS cache Compressed or Uncompressed data in a ZFS file-system with compression turned on?

  - by George Bailey

  ZFS supports file-system compression and it also caches frequently or recently accessed data. If a system has lots of CPU but the underlying data storage system is slow. It is possible that ZFS would perform better with compression turned on. This can be easily tested when writing files by measuring CPU and disk usage and throughput. (of course latency may exist,, but this would not be an issue for large files). But what about cache? If data will have to be decompressed every time it is read then this is probably less of a good idea. Is the cached data compressed?. Does anybody have some information on this?

• How Google Web Starter Kit serves adaptive image for mobile?

  - by 5argon

  My website weirdly (in a good way) serves smaller images when viewed on mobile. I wanted to know what cause this? As far as I know this is not the default behaviour, so I think it must be Google Web Starter Kit's doing.Here is the debug information when debugging on device. All images became 231 B size no matter how large it actually is. (On desktop debugging the size varies.) I tried using Google Web Starter Kit (https://github.com/google/web-starter-kit) recently. The tools in it are made of Ruby, Node.js, SASS and Gulp to help you 'build' website. Pre-build you can enjoy automatic reload because the Gulp script will watch all files for you. When build it will run various tools to minify HTML,CSS and compress images. According to this page https://developers.google.com/web/fundamentals/tools/build/build_site the gulp-imagemin was used. So I guess the imagemin is doing the mobile optimization for me? What kind of compression can serve automatically resized image on mobile? And why is the size 231 B? Is this related to my screen size?

• How to display part of an image for the specific width and height?

  - by Brady Chu

  Recently I participated in a web project which has a huge large of images to handle and display on web page, we know that the width and height of images end users uploaded cannot be control easily and then they are hard to display. At first, I attempted to zoom in/out the images to rearch an appropriate presentation, and I made it, but my boss is still not satisfied with my solution, the following is my way: var autoResizeImage = function(maxWidth, maxHeight, objImg) { var img = new Image(); img.src = objImg.src; img.onload = function() { var hRatio; var wRatio; var Ratio = 1; var w = img.width; var h = img.height; wRatio = maxWidth / w; hRatio = maxHeight / h; if (maxWidth == 0 && maxHeight == 0) { Ratio = 1; } else if (maxWidth == 0) { if (hRatio < 1) { Ratio = hRatio; } } else if (maxHeight == 0) { if (wRatio < 1) { Ratio = wRatio; } } else if (wRatio < 1 || hRatio < 1) { Ratio = (wRatio <= hRatio ? wRatio : hRatio); } if (Ratio < 1) { w = w * Ratio; h = h * Ratio; } w = w <= 0 ? 250 : w; h = h <= 0 ? 370 : h; objImg.height = h; objImg.width = w; }; }; This way is only intended to limit the max width and height for the image so that every image in album still has different width and height which are still very urgly. And right at this minute, I know we can create a DIV and use the image as its background image, this way is too complicated and not direct I don't want to take. So I's wondering whether there is a better way to display images with the fixed width and height without presentation distortion? Thanks.

• MPI: is there mpi libraries capable of message compression?

  - by osgx

  Sometimes MPI is used to send low-entropy data in messages. So it can be useful to try to compress messages before sending it. I know that MPI can work on very fast networks (10 Gbit/s and more), but many MPI programs are used with cheap network like 0,1G or 1Gbit/s Ethernet and with cheap (slow, low bisection) network switch. There is a very fast Snappy (wikipedia) compression algorithm, which has Compression speed is 250 MB/s and decompression speed is 500 MB/s so on compressible data and slow network it will give some speedup. Is there any MPI library which can compress MPI messages (at layer of MPI; not the compression of ip packets like in PPP). MPI messages are also structured, so there can be some special method, like compression of exponent part in array of double.

• Increase the compression performance of VPN

  - by Martin

  I am currently switching from a system with HPN-SSH tunnels and enabled compression to something VPN based. I have tried tinc and n2n so far, hamachi requires a library I do not have. In my primitive benchmarks I am not satisfied with the achievable bandwidth compared to the SSH tunnels. In tinc the low LZO setting performed best, but compression is only available in UDP mode. Ideally I would like to have a TCP-based VPN with a multi-threaded compression. Can you suggest me some ideas how to increase the performance? Would it be possible to somehow put a compression filter in front of the tun interface? Or are there any VPN implementations that might be better suited for my needs (fast compression, TCP-based, switch mode, does not have to be super-secure)? I would consider tunnelling Ethernet over SSH, but according to some articles it is not advisable.

  I have this code in Silverlight: Image image = new Image(); BitmapImage bitmapImage= TheDatasourceManager.GetBitmapImage("blackPencil"); image.Source = bitmapImage; image.Stretch = Stretch.None; image.HorizontalAlignment = HorizontalAlignment.Left; image.VerticalAlignment = VerticalAlignment.Top; image.Margin = new Thickness(88, 88, 0, 0); grid.Children.Add(image); Now I want to find out the height of the image. in WPF I can get it with image.Source.Height but this is not available in Silverlight bitmapImage.Height doesn't exist either when I debug and examine the image object, I eventually get to PixelHeight which has an accurate height, but I can't seem to access it I find image.ActualHeight but it is 0. How can I get the height of the image?
