  • How to commit a file conversion?

    - by l0b0
    Say you've committed a file of type foo in your favorite vcs: $ vcs add data.foo $ vcs commit -m "My data" After publishing you realize there's a better data format bar. To convert you can use one of these solutions: $ vcs mv data.foo data.bar $ vcs commit -m "Preparing to use format bar" $ foo2bar --output data.bar data.bar $ vcs commit -m "Actual foo to bar conversion" or $ foo2bar --output data.foo data.foo $ vcs commit -m "Converted data to format bar" $ vcs mv data.foo data.bar $ vcs commit -m "Renamed to fit data type" or $ foo2bar --output data.bar data.foo $ vcs rm data.foo $ vcs add data.bar $ vcs commit -m "Converted data to format bar" In the first two cases the conversion is not an atomic operation and the file extension is "lying" in the first commit. In the last case the conversion will not be detected as a move operation, so as far as I can tell it'll be difficult to trace the file history across the commit. Although I'd instinctively prefer the last solution, I can't help thinking that tracing history should be given very high priority in version control. What is the best thing to do here?

  • Simplest way to render image over top of another with another image used as mask in OpenGL?

    - by Adam Naylor
    The effect I'm looking for is to have a single large background image that is always visible (at full alpha) and then show a second image (what I call a light map or specular map) that is partially shown over the top based on a third image (which is effectively a mask). The effect is similar to this effect except instead of simply darkening or lightening the background image using the third image it needs to mask the second without effecting the first at all. The third image is the only one that moves therefore hard baking the third images alpha into the second image isn't an option. If my explanation isn't clear I'll provide visual examples when I have more time. I'd prefer not to go down a shader route as I haven't taught myself this area yet so unless I have too I'd rather try to achieve this with simple alpha blending. Happy to use a shader approach. Cheers. Additional These third images are obviously light sources being cast onto the first image showing the specular information from the second image to simulate the light 'shining' off the objects in the first image. The solution I implement will need to allow two light sources to potentially overlap so my current thoughts are that the alpha values of the two images will need to be combined (Added?) to produce a final image which masks the second image? Don't worry about things like coloured lights. For this technique the lights are all considered white.

  • Designing exceptions for conversion failures

    - by Mr.C64
    Suppose there are some methods to convert from "X" to "Y" and vice versa; the conversion may fail in some cases, and exceptions are used to signal conversion errors in those cases. Which would be the best option for defining exception classes in this context? A single XYConversionException class, with an attribute (e.g. an enum) specifying the direction of the conversion (e.g. ConversionFromXToY, ConversionFromYToX). A XYConversionException class, with two derived classes ConversionFromXToYException and ConversionFromYToXException. ConversionFromXToYException and ConversionFromYToXException classes without a common base class.

  • Split (parts of) image into several smaller (same size) pieces non-manually

    - by hlovdal
    If I have an image with a table containing several rows, say like the periodic table: Are there any tool I can use to split this into one smaller image with the H He row, another image for the Li Be ... Ne row, etc? The tool does not have to detect the row borders by itself, specifying a start offset + row height in pixels is ok. Manually selecting and cutting/copying in gimp is not an option, I have way to many rows to process.

  • Video/Image processing on Apple iPhone4 [closed]

    - by goldenmean
    Hello, I know apple iPhone4 support H.264 and MPEG-4 as the supported video codecs, and JPEG,M-JPEG as image codecs. I was looking to get some information on Apple iPhone4 Video, Image Codec and Processing Chips/SoC parts. 1] Does anyone know, Which vendor provides the SoC's to enable this image / video compression and processing solutions in iPhone4. 2] Are the video/image codec solutions - 'Software codecs' on a specialized dsp-core/processor or hard wired as in a FPGA/ASIC solution. Any pointers would be useful. thank you. -AD.

  • choosing an image locally from http url and serving that image without a server round trip

    - by serverman
    Hi folks I am a complete novice to Flash (never created anything in flash). I am quite familiar with web applications (J2EE based) and have a reasonable expertise in Javascript. Here is my requirement. I want the user to select (via an html form) an image. Normally in the post, this image would be sent to server and may be stored there to be served later. I do not want that. I want to store this image locally and then serve it via HTTP to the user. So, the flow is: 1. Go to the "select image url":mywebsite.com/selectImage Browse the image and select the image This would transfer control locally to some code running on the client (Javascript or flash), which would then store the image locally at some place on the client machine. Go to the "show image url": mywebsite.com/showImage This would eventually result in some client code running on the browser that retrieves the image and renders it (without any server round trips.) I considered the following options: Use HTML5 local storage. Since I am a complete novice to flash, I looked into this. I found that it is fairly straightforward to store and retrieve images in javascript (only strings are allowed but I am hoping storing base64 encoded strings would work at least for small images). However, how do I serve the image via http url that points to my server without a server round trip? I saw the interesting article at http://hacks.mozilla.org/category/fileapi/ but that would work only in firefox and I need to work on all latest browsers (at least the ones supporting HTML5 local storage) Use flash SharedObjects. OK, this would have been good - the only thing is I am not sure where to start. Snippets of actionscripts to do this are scattered everywhere but I do not know how to use those scripts in an actual html page:) I do not need to create any movies or anything - just need to store an image and serve it locally. If I go this route, I would also use it to store other "strings" locally. If you suggest this, please give me the exact steps (could be pointers to other web sites) on how to do this. I would like to avoid paying for any flash development environment software ideally:) Thank you!

  • How to write PIL image filter for plain pgm format?

    - by Juha
    How can I write a filter for python imaging library for pgm plain ascii format (P2). Problem here is that basic PIL filter assumes constant number of bytes per pixel. My goal is to open feep.pgm with Image.open(). See http://netpbm.sourceforge.net/doc/pgm.html or below. Alternative solution is that I find other well documented ascii grayscale format that is supported by PIL and all major graphics programs. Any suggestions? br, Juha feep.pgm: P2 # feep.pgm 24 7 15 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 3 3 3 3 0 0 7 7 7 7 0 0 11 11 11 11 0 0 15 15 15 15 0 0 3 0 0 0 0 0 7 0 0 0 0 0 11 0 0 0 0 0 15 0 0 15 0 0 3 3 3 0 0 0 7 7 7 0 0 0 11 11 11 0 0 0 15 15 15 15 0 0 3 0 0 0 0 0 7 0 0 0 0 0 11 0 0 0 0 0 15 0 0 0 0 0 3 0 0 0 0 0 7 7 7 7 0 0 11 11 11 11 0 0 15 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 edit: Thanks for the answer, I works... but I need a solution that uses Image.open(). Most of python programs out there use PIL for graphics manipulation (google: python image open). Thus, I need to be able to register a filter to PIL. Then, I can use any software that uses PIL. I now think mostly scipy, pylab, etc. dependent programs.

  • jQuery image crossfader problem

    - by Dr Casper Black
    Hey!, I have a image switcher fadein/out (it will crossfade iamges - auto(1 - x) ) and a pager but i cant manage to make the image rotation listen the click action on pager, when clicked on pager the image will NOT jup tu the specific img. The problem is in the rotate function the triggerID will hold the "rel" num of the current pager-element which is the equivalent to the image "list" num, so when clicked on the pager, the triggerID will show the rel number that was clicked... can i use that to display the image Here is the code for JQ: $(".paging a:first").addClass("active"); //Rotation rotate = function(){ var triggerID = $active.attr("rel"); //Get number of times to images $(".paging a").removeClass('active'); //Remove all active class $active.addClass('active'); //Add active class (the $active is declared in the rotateSwitch function) //CrossFade Animation var $activeImg = $('.image_reel img.active'); if ( $activeImg.length == 0 ) $activeImg = $('.image_reel img:last'); var $next = $activeImg.next().length ? $activeImg.next() : $('.image_reel img:first'); $activeImg.addClass('last-active'); $next.css({opacity: 0.0}) .addClass('active') .animate({opacity: 1.0}, 500, function() { $activeImg.removeClass('active last-active'); }); }; //Rotation and Timing Event rotateSwitch = function(){ play = setInterval(function(){ //Set timer - this will repeat itself every 3 seconds $active = $('.paging a.active').next(); //Move to the next paging if ( $active.length === 0) { //If paging reaches the end... $active = $('.paging a:first'); //go back to first } rotate(); //Trigger the paging and slider function }, 3000); //Timer speed in milliseconds (3 seconds) }; rotateSwitch(); //Run function on launch //On Click $(".paging a").click(function() { $active = $(this); //Activate the clicked paging //Reset Timer clearInterval(play); //Stop the rotation rotate(); //Trigger rotation immediately rotateSwitch(); // Resume rotation timer return false; //Prevent browser jump to link anchor }); The HTML code: <div class="image_reel"> <img src="images/slideshow/img1.jpg" alt="image 1" class="active"> <img src="images/slideshow/img2.jpg" alt="image 2"> <img src="images/slideshow/img3.jpg" alt="image 3"> <img src="images/slideshow/img4.jpg" alt="image 4"> </div> <div class="paging"> <a href="#" rel="1" title="image 1">&nbsp;</a> <a href="#" rel="2" title="image 2">&nbsp;</a> <a href="#" rel="3" title="image 3">&nbsp;</a> <a href="#" rel="4" title="image 4">&nbsp;</a> </div> plz help.

  • iPhone: How to Maintain Original Image Size Thoughout Image Edits

    - by maddy
    hi, I am developing an iPhone app that resizes and merges images. I want to select two photos of size 1600x1200 from photo library and then merge both into a single image and save that new image back to the photo library. However, I can't get the right size for the merged image. I take two image views of frame 320x480 and set the view's image to my imported images. After manipulating the images (zooming, cropping, rotating), I then save the image to album. When I check the image size it shows 600x800. How do I get the original size of 1600*1200? I've been stuck on this problem from two weeks! Thanks in advance.

  • PHP Image resize - Why is the image uploaded but not resized?

    - by Hans
    BACKGROUND I have a script to upload an image. One to keep the original image and one to resize the image. 1. If the image dimensions (width & height) are within max dimensions I use a simple "copy" direct to folder UserPics. 2. If the original dimensions are bigger than max dimensions I want to resize the width and height to be within max. Both of them are uploading the image to the folder, but in case 2, the image will not be resized. QUESTION Is there something wrong with the script? Is there something wrong with the settings? SETTINGS Server: WAMP 2.0 PHP: 5.3.0 PHP.ini: GD2 enabled, Memory=128M (have tried 1000M) Tried imagetypes uploaded: jpg, jpeg, gif, and png (same result for all of them) SCRIPT //Uploaded image $filename = stripslashes($_FILES['file']['name']); //Read filetype $i = strrpos($filename,"."); if (!$i) { return ""; } $l = strlen($filename) - $i; $extension = substr($filename,$i+1,$l); $extension = strtolower($extension); //New picture name = maxid+1 (from database) $query = mysql_query("SELECT MAX(PicId) AS number FROM userpictures"); $row = mysql_fetch_array($query); $imagenumber = $row['number']+1; //New name of image (including path) $image_name=$imagenumber.'.'.$extension; $newname = "UserPics/".$image_name; //Check width and height of uploaded image list($width,$height)=getimagesize($uploadedfile); //Check memory to hold this image (added only as checkup) $imageInfo = getimagesize($uploadedfile); $requiredMemoryMB = ( $imageInfo[0] * $imageInfo[1] * ($imageInfo['bits'] / 8) * $imageInfo['channels'] * 2.5 ) / 1024; echo $requiredMemoryMB."<br>"; //Max dimensions that can be uploaded $maxwidth = 20; $maxheight = 20; // Check if dimensions shall be original if ($width > $maxwidth || $height > $maxheight) { //Make jpeg from uploaded image if ($extension=="jpg" || $extension=="jpeg" || $extension=="pjpeg" ) { $modifiedimage = imagecreatefromjpeg($uploadedfile); } elseif ($extension=="png") { $modifiedimage = imagecreatefrompng($uploadedfile); } elseif ($extension=="gif") { $modifiedimage = imagecreatefromgif($uploadedfile); } //Change dimensions if ($width > $height) { $newwidth = $maxwidth; $newheight = ($height/$width)*$newwidth; } else { $newheight = $maxheight; $newwidth = ($width/$height)*$newheight; } //Create new image with new dimensions $newdim = imagecreatetruecolor($newwidth,$newheight); imagecopyresized($newdim,$modifiedimage,0,0,0,0,$newwidth,$newheight,$width,$height); imagejpeg($modifiedimage,$newname,60); // Remove temp images imagedestroy($modifiedimage); imagedestroy($newdim); } else { // Just add picture to folder without resize (if org dim < max dim) $newwidth = $width; $newheight = $height; $copied = copy($_FILES['file']['tmp_name'], $newname); } //Add image information to the MySQL database mysql_query("SET character_set_connection=utf8", $dbh); mysql_query("INSERT INTO userpictures (PicId, Picext, UserId, Width, Height, Size) VALUES('$imagenumber', '$extension', '$_SESSION[userid]', '$newwidth', '$newheight', $size)")

  • How to get image from relative URL in C#, the image cannot be in the project

    - by red-X
    I have a project where I'm loading relative image Uri's from an xml file. I'm loading the image like this: if (child.Name == "photo" && child.Attributes["href"] != null && File.Exists(child.Attributes["href"].Value)) { Image image = new Image(); image.Source = new BitmapImage(new Uri(child.Attributes["href"].Value, UriKind.RelativeOrAbsolute)); images.Add(image); } Where the "child" object is an XmlNode which could looks like this <photo name="info" href="Resources\Content\test.png"/> During debug it seemd images is filled with actual images but when I want to see them in any way it shows nothing. Weird thing is when I include the images in my project it does work, I however dont want to do that since my point for using an xml file is so that it would be lost since you'd have to rebuild the program anyway after a change.

  • Units of measurement conversion logic in C#

    - by EvanRyan
    I am adding a feature to my program in which the user will have the ability to change their unit of measurement at any time, and have the program recalculate their input and output. If the user inputs say, 20lbs for an item, then decides he wants to work in kilograms instead, he can select an option to do so at any time, and the program will recalculate his 20lb input to 9Kg. Then if he decides he'd rather work in ounces, it would convert that 9Kg to 320oz, so on and so forth. What would be the most effective and efficient way to go about this? I've been racking my brain trying to figure out a way to have the correct formula be implemented.

  • Letters in base-conversion

    - by tech_geek23
    I have this code written so far and is correct, aside from not using A-F when the value is over 10: public class TenToAny { private int base10; private int newBase; public TenToAny() { } public TenToAny(int ten, int base) { base10 = ten; newBase = base; } public void setNums(int ten, int base) { base10 = ten; newBase = base; } public String getNewNum() { String newNum=""; int orig = base10; //int first = newBase - 1; while(orig > 0) { newNum = orig%newBase + newNum; orig = orig/newBase; } return newNum; } public String toString() { String complete = base10 + " base 10 is " + getNewNum() + " in base " + newBase; return complete; } } Obviously I don't have anything relating to values over 10 converting to A-F as I've never dealt with these before. Any help is appreciated. Here's my runner class: public class Lab09i { public static void main( String args[] ) { TenToAny test = new TenToAny(234, 9); out.println(test); test.setNums(100, 2); out.println(test); test.setNums(10, 2); out.println(test); test.setNums(15, 2); out.println(test); test.setNums(256, 2); out.println(test); test.setNums(100, 8); out.println(test); test.setNums(250, 16); out.println(test); test.setNums(56, 11); out.println(test); test.setNums(89, 5); out.println(test); test.setNums(23, 3); out.println(test); test.setNums(50, 5); out.println(test); test.setNums(55, 6); out.println(test); test.setNums(2500, 6); out.println(test); test.setNums(2500, 13); out.println(test); } } this is what my results should be: 234 base 10 is 280 in base 9 100 base 10 is 1100100 in base 2 10 base 10 is 1010 in base 2 15 base 10 is 1111 in base 2 256 base 10 is 100000000 in base 2 100 base 10 is 144 in base 8 250 base 10 is FA in base 16 56 base 10 is 51 in base 11 89 base 10 is 324 in base 5 23 base 10 is 212 in base 3 50 base 10 is 302 in base 4 55 base 10 is 131 in base 6 2500 base 10 is 9C4 in base 16 2500 base 10 is 11A4 in base 13

  • javascript arrays and type conversion inconsistencies

    - by ForYourOwnGood
    I have been playing with javascript arrays and I have run into, what I feel, are some inconsistencies, I hope someone can explain them for me. Lets start with this: var myArray = [1, 2, 3, 4, 5]; document.write("Length: " + myArray.length + "<br />"); for( var i in myArray){ document.write( "myArray[" + i + "] = " + myArray[i] + "<br />"); } document.write(myArray.join(", ") + "<br /><br />"); Length: 5 myArray[0] = 1 myArray[1] = 2 myArray[2] = 3 myArray[3] = 4 myArray[4] = 5 1, 2, 3, 4, 5 There is nothing special about this code, but I understand that a javascript array is an object, so properities may be add to the array, the way these properities are added to an array seems inconsistent to me. Before continuing, let me note how string values are to be converted to number values in javascript. Nonempty string - Numeric value of string or NaN Empty string - 0 So since a javascript array is an object the following is legal: myArray["someThing"] = "someThing"; myArray[""] = "Empty String"; myArray["4"] = "four"; for( var i in myArray){ document.write( "myArray[" + i + "] = " + myArray[i] + "<br />"); } document.write(myArray.join(", ") + "<br /><br />"); Length: 5 myArray[0] = 1 myArray[1] = 2 myArray[2] = 3 myArray[3] = 4 myArray[4] = four myArray[someThing] = someThing myArray[] = Empty String 1, 2, 3, 4, four The output is unexpected. The non empty string "4" is converted into its numeric value when setting the property myArray["4"], this seems right. However the empty string "" is not converted into its numeric value, 0, it is treated as an empty string. Also the non empty string "something" is not converted to its numeric value, NaN, it is treated as a string. So which is it? is the statement inside myArray[] in numeric or string context? Also, why are the two, non numeric, properities of myArray not included in myArray.length and myArray.join(", ")?

  • Implicit conversion : const reference vs non-const reference vs non-reference

    - by Nawaz
    Consider this code, struct A {}; struct B { B(const A&) {} }; void f(B) { cout << "f()"<<endl; } void g(A &a) { cout << "g()" <<endl; f(a); //a is implicitly converted into B. } int main() { A a; g(a); } This compiles fine, runs fine. But if I change f(B) to f(B&), it doesn't compile. If I write f(const B&), it again compiles fine, runs fine. Why is the reason and rationale? Summary: void f(B); //okay void f(B&); //error void f(const B&); //okay I would like to hear reasons, rationale and reference(s) from the language specification, for each of these cases. Of course, the function signatures themselves are not incorrect. Rather A implicitly converts into B and const B&, but not into B&, and that causes the compilation error.

  • Python, a smarter way of string to integer conversion

  • How do you position a background image inside a <div>?

  • convert string to float without silent NaN/Inf conversion

    - by Peter Hansen
    I'd like convert strings to floats using Python 2.6 and later, but without silently converting things like 'NaN' and 'Inf'. Before 2.6, float("NaN") would raise a ValueError. Now it returns a float for which math.isnan() returns True, which is not useful behaviour for my application. Here's what I've got at the moment: import math def get_floats(source): for text in source.split(): try: val = float(text) if math.isnan(val) or math.isinf(val): raise ValueError yield val except ValueError: pass This is a generator, which I can supply with strings containing whitespace-separated sequences representing real numbers. I'd like it to yield only those fields which are purely numeric representations of floats, as in "1.23" or "-34e6", but not for example "NaN" or "-Inf". Test case: assert list(get_floats('1.23 -34e6 NaN -Inf')) == [1.23, -34000000.0] Please suggest alternatives you consider more elegant, even if they involve "look before you leap" (which is normally considered a lesser approach in Python).
