  • Improve my php image resizer to support alpha png and transparent GIFs

    - by David
    Hi, I use this function to resize images but i end up with ugly creepy image with a black background if it's a transparent GIF or PNG with alpha, however it works perfectly for jpg and normal png. function cropImage($nw, $nh, $source, $stype, $dest) { $size = getimagesize($source); $w = $size[0]; $h = $size[1]; switch($stype) { case 'gif': $simg = imagecreatefromgif($source); break; case 'jpg': $simg = imagecreatefromjpeg($source); break; case 'png': $simg = imagecreatefrompng($source); break; } $dimg = imagecreatetruecolor($nw, $nh); switch ($stype) { case "png": imagealphablending( $dimg, false ); imagesavealpha( $dimg, true ); $transparent = imagecolorallocatealpha($dimg, 255, 255, 255, 127); imagefilledrectangle($dimg, 0, 0, $nw, $nh, $transparent); break; case "gif": // integer representation of the color black (rgb: 0,0,0) $background = imagecolorallocate($simg, 0, 0, 0); // removing the black from the placeholder imagecolortransparent($simg, $background); break; } $wm = $w/$nw; $hm = $h/$nh; $h_height = $nh/2; $w_height = $nw/2; if($w> $h) { $adjusted_width = $w / $hm; $half_width = $adjusted_width / 2; $int_width = $half_width - $w_height; imagecopyresampled($dimg,$simg,-$int_width,0,0,0,$adjusted_width,$nh,$w,$h); } elseif(($w <$h) || ($w == $h)) { $adjusted_height = $h / $wm; $half_height = $adjusted_height / 2; $int_height = $half_height - $h_height; imagecopyresampled($dimg,$simg,0,-$int_height,0,0,$nw,$adjusted_height,$w,$h); } else { imagecopyresampled($dimg,$simg,0,0,0,0,$nw,$nh,$w,$h); } imagejpeg($dimg,$dest,100); } I use php 5.3.2 and the GD library bundled (2.0.34 compatible) Thanks

  • Cannot call external javascript function from SITE.MASTER

    I have a Site.Master in my ASP.NET project which defines a HEAD section as follows <head runat="server"> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <title id="MasterTitle">MyApp</title> <link rel="icon" href="Content/icon.ico" type="image/x-icon" /> <link href="Content/mycss.css" rel="stylesheet" type="text/css" /> <script src="Content/mycode.js" type="text/javascript"></script> </head> In the mycode.js file, I have a function called GetSels(); function GetSels() { //do stuff } If the GetSels function is defined in Site.Master, GetSels is callable. If it's in mycode.js, it's not. Every code example I've see seems to says this should work. What am I doing wrong?

  • Xcode 4: deleting items in Build Settings

    - by occulus
    In XCode 4.0 there's a newly designed Build Settings page. My problem is that I can't see how to remove a setting once I've specified it. Example: I've changed "Versioning System" to "Apple Generic" at the target level. Afterwards I realised I should set it at the project level, and so I want to delete the target level setting. However, there's no way I can see to remove the setting -- you click on it and there's two options, neither of which is the default "not specified" empty setting. Hitting the delete key on the keyboard nothing. The same goes for fields that accept text -- if I try to delete a setting by just deleting all the text set, it still shows that field in green, but with no text in it, and regards it as the presence of a setting.

  • How do I improve my performance with this singly linked list struct within my program?

    - by Jesus
    Hey guys, I have a program that does operations of sets of strings. We have to implement functions such as addition and subtraction of two sets of strings. We are suppose to get it down to the point where performance if of O(N+M), where N,M are sets of strings. Right now, I believe my performance is at O(N*M), since I for each element of N, I go through every element of M. I'm particularly focused on getting the subtraction to the proper performance, as if I can get that down to proper performance, I believe I can carry that knowledge over to the rest of things I have to implement. The '-' operator is suppose to work like this, for example. Declare set1 to be an empty set. Declare set2 to be a set with { a b c } elements Declare set3 to be a set with ( b c d } elements set1 = set2 - set3 And now set1 is suppose to equal { a }. So basically, just remove any element from set3, that is also in set2. For the addition implementation (overloaded '+' operator), I also do the sorting of the strings (since we have to). All the functions work right now btw. So I was wondering if anyone could a) Confirm that currently I'm doing O(N*M) performance b) Give me some ideas/implementations on how to improve the performance to O(N+M) Note: I cannot add any member variables or functions to the class strSet or to the node structure. The implementation of the main program isn't very important, but I will post the code for my class definition and the implementation of the member functions: strSet2.h (Implementation of my class and struct) // Class to implement sets of strings // Implements operators for union, intersection, subtraction, // etc. for sets of strings // V1.1 15 Feb 2011 Added guard (#ifndef), deleted using namespace RCH #ifndef _STRSET_ #define _STRSET_ #include <iostream> #include <vector> #include <string> // Deleted: using namespace std; 15 Feb 2011 RCH struct node { std::string s1; node * next; }; class strSet { private: node * first; public: strSet (); // Create empty set strSet (std::string s); // Create singleton set strSet (const strSet &copy); // Copy constructor ~strSet (); // Destructor int SIZE() const; bool isMember (std::string s) const; strSet operator + (const strSet& rtSide); // Union strSet operator - (const strSet& rtSide); // Set subtraction strSet& operator = (const strSet& rtSide); // Assignment }; // End of strSet class #endif // _STRSET_ strSet2.cpp (implementation of member functions) #include <iostream> #include <vector> #include <string> #include "strset2.h" using namespace std; strSet::strSet() { first = NULL; } strSet::strSet(string s) { node *temp; temp = new node; temp->s1 = s; temp->next = NULL; first = temp; } strSet::strSet(const strSet& copy) { if(copy.first == NULL) { first = NULL; } else { node *n = copy.first; node *prev = NULL; while (n) { node *newNode = new node; newNode->s1 = n->s1; newNode->next = NULL; if (prev) { prev->next = newNode; } else { first = newNode; } prev = newNode; n = n->next; } } } strSet::~strSet() { if(first != NULL) { while(first->next != NULL) { node *nextNode = first->next; first->next = nextNode->next; delete nextNode; } } } int strSet::SIZE() const { int size = 0; node *temp = first; while(temp!=NULL) { size++; temp=temp->next; } return size; } bool strSet::isMember(string s) const { node *temp = first; while(temp != NULL) { if(temp->s1 == s) { return true; } temp = temp->next; } return false; } strSet strSet::operator + (const strSet& rtSide) { strSet newSet; newSet = *this; node *temp = rtSide.first; while(temp != NULL) { string newEle = temp->s1; if(!isMember(newEle)) { if(newSet.first==NULL) { node *newNode; newNode = new node; newNode->s1 = newEle; newNode->next = NULL; newSet.first = newNode; } else if(newSet.SIZE() == 1) { if(newEle < newSet.first->s1) { node *tempNext = newSet.first; node *newNode; newNode = new node; newNode->s1 = newEle; newNode->next = tempNext; newSet.first = newNode; } else { node *newNode; newNode = new node; newNode->s1 = newEle; newNode->next = NULL; newSet.first->next = newNode; } } else { node *prev = NULL; node *curr = newSet.first; while(curr != NULL) { if(newEle < curr->s1) { if(prev == NULL) { node *newNode; newNode = new node; newNode->s1 = newEle; newNode->next = curr; newSet.first = newNode; break; } else { node *newNode; newNode = new node; newNode->s1 = newEle; newNode->next = curr; prev->next = newNode; break; } } if(curr->next == NULL) { node *newNode; newNode = new node; newNode->s1 = newEle; newNode->next = NULL; curr->next = newNode; break; } prev = curr; curr = curr->next; } } } temp = temp->next; } return newSet; } strSet strSet::operator - (const strSet& rtSide) { strSet newSet; newSet = *this; node *temp = rtSide.first; while(temp != NULL) { string element = temp->s1; node *prev = NULL; node *curr = newSet.first; while(curr != NULL) { if( element < curr->s1 ) break; if( curr->s1 == element ) { if( prev == NULL) { node *duplicate = curr; newSet.first = newSet.first->next; delete duplicate; break; } else { node *duplicate = curr; prev->next = curr->next; delete duplicate; break; } } prev = curr; curr = curr->next; } temp = temp->next; } return newSet; } strSet& strSet::operator = (const strSet& rtSide) { if(this != &rtSide) { if(first != NULL) { while(first->next != NULL) { node *nextNode = first->next; first->next = nextNode->next; delete nextNode; } } if(rtSide.first == NULL) { first = NULL; } else { node *n = rtSide.first; node *prev = NULL; while (n) { node *newNode = new node; newNode->s1 = n->s1; newNode->next = NULL; if (prev) { prev->next = newNode; } else { first = newNode; } prev = newNode; n = n->next; } } } return *this; }

  • How to make overflow: hidden really hide content?

    - by tambourine
    Please, look at this example. I intend making horizontal layout with pure html/css, don't bother of old browsers. I made it with display: table technique. But displaying main text containers (light-yellow) became a problem. Each of this has overflow: hidden to prevent vertical scroll. Later, I intend adding some shadow effect at the bottom. Now, I want to make in, for example, 80% height with 10% margin top and bottom. But what I get is container with larger text stretching all parents container (light-green), so 80% of it became too much. Is there any way to avoid it without javascript? Maybe I can get text container any height, but with some margin at the bottom. I will appreciate any solution.

  • Palm webOS CSS Targeting Hack?

    - by Tom
    Although it is not good practice, I am looking for a CSS hack to target Palm webOS. The problem is that Safari 3+ is awesome, and I can do some things like gradient background animations on text, but only in Safari. Right now I use @media screen and (-webkit-min-device-pixel-ratio:0) {} and it works like a charm, no Opera, Firefox, or whatever, because if I set the background to the image as I do in Safari they will all be ruined. But Palm's browser is based on webkit, and it uses the rules inside, and Palm's browser doesn't support text backgrounds so all I get is the image moving, no text. I would prefer a CSS hack, but if need be a Javascript one will do.

  • P/Invoke a Function Passed a StringBuilder

    - by andrew
    in a C# file i have a class Archiver { [DllImport("Archiver.dll")] public static extern void archive(string data, StringBuilder response); } string data is an input, and StringBuilder response is where the function writes something the archive function prototype (written in C) looks like this: void archive(char * dataChr, char * outChr); and it receives a string in dataChr, and then does a strcpy(outChr,"some big text"); from C# i call it something like this: string message = "some text here"; StringBuilder response = new StringBuilder(10000); Archiver.archive(message,response); this works, but the problem, as you might see is that i give a value to the StringBuilder size, but the archive function might give back a (way) larger text than the size i've given to my StringBuilder. any way to fix this?

  • Count problem in SQL when I want results from diffrent tabels

    - by Nicklas
    ALTER PROCEDURE GetProducts @CategoryID INT AS SELECT COUNT(tblReview.GroupID) AS ReviewCount, COUNT(tblComment.GroupID) AS CommentCount, Product.GroupID, MAX(Product.ProductID) AS ProductID, AVG(Product.Price) AS Price, MAX (Product.Year) AS Year, MAX (Product.Name) AS Name, AVG(tblReview.Grade) AS Grade FROM tblReview, tblComment, Product WHERE (Product.CategoryID = @CategoryID) GROUP BY Product.GroupID HAVING COUNT(distinct Product.GroupID) = 1 This is what the tabels look like: **Product** |**tblReview** | **tblComment** ProductID | ReviewID | CommentID Name | Description | Description Year | GroupID | GroupID Price | Grade | GroupID GroupID is name_year of a Product, ex Nike_2010. One product can have diffrent sizes for exampel: ProductID | Name | Year | Price | Size | GroupID 1 | Nike | 2010 | 50 | 8 | Nike_2010 2 | Nike | 2010 | 50 | 9 | Nike_2010 3 | Nike | 2010 | 50 | 10 | Nike_2010 4 | Adidas| 2009 | 45 | 8 | Adidas_2009 5 | Adidas| 2009 | 45 | 9 | Adidas_2009 6 | Adidas| 2009 | 45 | 10 | Adidas_2009 I dont get the right count in my tblReview and tblComment. If I add a review to Nike size 8 and I add one review to Nike size 10 I want 2 count results when I list the products with diffrent GroupID. Now I get the same count on Reviews and Comment and both are wrong. I use a datalist to show all the products with diffrent/unique GroupID, I want it to be like this: ______________ | | | Name: Nike | | Year: 2010 | | (All Sizes) | | x Reviews | | x Comments | | x AVG Grade | |______________| All Reviewcounts, Commentcounts and the Average of all products with the same GroupID, the Average works great.

  • How to start writing out an existing AudioQueue in response to an event?

    - by Halle
    Hello, I am writing a class that opens an AudioQueue and analyzes its characteristics, and then under certain conditions can begin or end writing out a file from that AudioQueue that is already instantiated. This is my code (entirely based on SpeakHere) that opens the AudioQueue without writing anything out to tmp: void AQRecorder::StartListen() { int i, bufferByteSize; UInt32 size; try { SetupAudioFormat(kAudioFormatLinearPCM); XThrowIfError(AudioQueueNewInput(&mRecordFormat, MyInputBufferHandler, this, NULL, NULL, 0, &mQueue), "AudioQueueNewInput failed"); mRecordPacket = 0; size = sizeof(mRecordFormat); XThrowIfError(AudioQueueGetProperty(mQueue, kAudioQueueProperty_StreamDescription, &mRecordFormat, &size), "couldn't get queue's format"); bufferByteSize = ComputeRecordBufferSize(&mRecordFormat, kBufferDurationSeconds); for (i = 0; i < kNumberRecordBuffers; ++i) { XThrowIfError(AudioQueueAllocateBuffer(mQueue, bufferByteSize, &mBuffers[i]), "AudioQueueAllocateBuffer failed"); XThrowIfError(AudioQueueEnqueueBuffer(mQueue, mBuffers[i], 0, NULL), "AudioQueueEnqueueBuffer failed"); } mIsRunning = true; XThrowIfError(AudioQueueStart(mQueue, NULL), "AudioQueueStart failed"); } catch (CAXException &e) { char buf[256]; fprintf(stderr, "Error: %s (%s)\n", e.mOperation, e.FormatError(buf)); } catch (...) { fprintf(stderr, "An unknown error occurred\n"); } } But I'm a little unclear on how to write a function that will tell this queue "from now until the stop signal, start writing out this queue to tmp as a file". I understand how to tell an AudioQueue to write out as a file at the time that it's created, how to set files format, etc, but not how to tell it to start and stop midstream. Much appreciative of any pointers, thanks.

  • Large quotation marks in Word?

    - by hawbsl
    Is there a simple way in MS Word to get large quotation marks tightly round a paragraph of text, like you might see in print media to mark a quote? If you simply increase the font size of the quote character, it moves too far away from the text it's accompanying. Worse, the first and last lines start to detach from the rest of the paragraph. Here's what I mean (this is Calibri I think): But this is the desired effect (can't do this in Word, had to chop it about in a paint package):

  • How to detect when UITextField become empty

I thought about using two methods - (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string; and - (BOOL)textFieldShouldClear:(UITextField *)textField; from UITextFieldDelegate I'm not sure how to detect the situation when the text field becomes empty? I tried with: if ([textField.text length] == 0) but it does't work as the fisrt of the above methods is called before the sign is deleted from the text field. Any ideas?

Using text view I can play with string being displayed but I cannot draw the line between messages or round rectangle surrounding user name and time stamp. Can anyone suggest me how can I achieve same look and feel for central message view as in skype?? or is there any better control then NSTextView to be used for it?? Thanks, for any suggestion...

  • Sorting by custom field and fetching whole tree from DB

    - by Niaxon
    Hello everyone, I am trying to do file browser in a tree form and have a problem to sort it somehow. I use PHP and MySQL for that. I've created mixed (nested set + adjacency) table 'element' with the following fields: element_id, left_key, right_key, level, parent_id, element_name, element_type (enum: 'folder','file'), element_size. Let's not discuss right now that it is better to move information about element (name, type, size) into other table. Function to scan specified directory and fill table work correctly. Noteworthy, i am adding elements to tree in specific order: folders first and then files. After that i can easily fetch and display whole table on the page using simple query: SELECT * FROM element WHERE 1=1 ORDER BY left_key With the result of that query and another function i can generate correct html code (<ul><li>... and so on). to display tree. Now back to the question (finally, huh?). I am struggling to add sorting functionality. For example i want to order my result by size. Here i need to keep in my mind whole hierarchy of tree and rule: folders first, files later. I believe i can do that by generating in PHP recursive query: SELECT * FROM element WHERE parent_id = {$parentId} ORDER BY element_type (so folders would be first), size (or name for example) asc/desc After that for each result which has type = 'folder' i will send another query to get it's content. Also it's possible to fetch whole tree by left_key and after that sort it in PHP as array but i guess that would be worse :) I wonder if there is better and more efficient way to do such a thing?

  • ms excel find and replace @ symbol results in broken formula

    - by Loopo
    I'm trying to search and replace in excel, the column is formatted as 'Text'. Find: [@ replace with: @ Whenever this finds a match at the start of a cell i.e the cell contents start with [@ and tries to replace that with @ the result is an error 'This function is not valid' I guess that since the @ operator is for references, this is causing the cell to be interpreted differently (not as text anymore) How do I make this replacement work? Copy/paste into another program is not a good option because some of the cells contain line-breaks.

  • Clear Input onFocus with Google Custom Search

    - by Wes
    I'm moving a sites search over to google custom search. The old input for text looks like this: <input type="text" value="Search this website..." name="s" id="searchbox" onfocus="if (this.value == 'Search this website...') {this.value = '';}" onblur="if (this.value == '') {this.value = 'Search this website...';}" /> Now I need to Have the attr 'name' as 'q', like so: <input type="text" value="Search this website..." name="q" id="searchbox" onfocus="if (this.value == 'Search this website...') {this.value = '';}" onblur="if (this.value == '') {this.value = 'Search this website...';}" /> The odd thing is that when I swap the name over to q, I'm unable to clear the search box on focus. Am I missing something super easy?
