• Using the Microsoft Ajax Minifier with Web Setup project & Source Control

  - by Rob

  I've just started investigating the Microsoft Ajax Minifer 4.0 for use with a Visual Studio 2008 Web Application I work on. It's proven easy enough to hook it into the .csproj file so it produced .min.js files for all scripts, however I'm stumped as to how to integrate this with the Web Setup project & Source Control. Essentially what I want to do is have the resultant .min.js files included in the Web Setup project without having them included in Source Control because: Having to check them out prior to the build being executing is a pain (the minifier cannot modify them if they're not checked out). As they're created as a "build artifact" it just seems wrong to have them stored under source control. The only option I've managed to come across so far is to explicitly include the .min.js files as part of the Setup project by right clicking on the Web Setup project and choosing "Add File", and then having the relevant folder hierarchy duplicated in "File System on Target Machine" so that I can force the file to the correct location. This is neither elegant or simple/robust as: It requires me to manually add every minified js file to the Web Setup project by hand Maintain a copy of the relevant directory structure in both the Web Application project and the Web Setup project Remember to add any new js files minified versions to the Web Setup project Is there a better way of doing this?

• Use jQuery to find and add an image tooltip

  - by lund.mikkel

  Hey people Okay, what I'm trying to accomplish is a simple tool tip that, when you hover over the name of a color, shows a little image of that color. The html markup looks like this: <label class="colorPicker"> <input type="radio" checked="" id="20" value="20" name="id[2]"> <img width="16" height="16" title=" DinoBlack Mat " alt="DinoBlack Mat" src="images/attributes/color/dinoblack_mat.jpg">DinoBlack Mat </label> <label class="colorPicker"> <input type="radio" id="874" value="874" name="id[2]"> <img width="16" height="16" title="XrayBlue shiny" alt="XrayBlue shiny" src="images/attributes/color/xrayblue_shiny.jpg">XrayBlue shiny </label> I'm using the jQuery plugin "Tooltip" and I've added following to my main js-file: $('.colorPicker').tooltip({ track: true, delay: 0, showURL: false, fade: 250, bodyHandler: function() { return $("<img/>").attr("src", [THE SOURCE FOR THE IMAGE]); } }); The idea is simply that the image should be hidden by default. But when you hover over the text the little thumbnail shows up and makes it easy to recognize the color. The problem is I haven't got a clue how to get the src for the thumbnail. I don't know how to extract the src from the img inside the selected element. I've tried various combinations using the this keyword, but nothing seemed to work. I've also tried to add the src path as a rel attribute to the label, but also without any success. Should be needless to say I also control the PHP-output... I really hope you can help me. I've search the web for days without any luck. I'm getting desperate :D /Mikkel Lund

• Why my custom CStatic derived control does not receive WM_SIZE message?

  - by Michael P

  Hello everyone! I'm currently developing a custom control that derives from CStatic MFC class (Smart Device C++ project). I have created the control class using VC++ MFC class wizard, selecting CStatic class as its base class. I have used Class View to add OnSize event handler for my control class (I have selected WM_SIZE message from messages list), and new OnSize method has been created by Visual Studio along with ON_WM_SIZE() statement between BEGIN_MESSAGE_MAP(...) and END_MESSAGE_MAP(). The problem is that my control does not receive WM_SIZE thus OnSize method is never called - I used MoveWindow to change size of my control - its size changes as I have seen on dialog window but WM_SIZE message is never being sent. When I send WM_SIZE through SendMessage or PostMessage function - the control OnSize method is called normally. What do I wrong? I've read MSDN docs about CStatic control and there is no information that WM_SIZE message is never sent to a static control window. Sorry for my bad English.

• Drawing Quadratic Bezier circles with a given radius: how to determine control points

  - by Casey

  Just to clarify; the code below works, but I don't understand where the formula for the variable "controlRadius" comes from. I wrote this function by dissecting an example I found elsewhere, but I can't find any explanation and the original code comments were not able to be translated. Thanks in advance //returns an array of quadratic Bezier segments public static function generateCircularQuadraticBezierSegments(radius:Number, numControlPoints:uint, centerX:Number, centerY:Number):Array { var segments:Array = []; var arcLength:Number = 2 * Math.PI / numControlPoints; var controlRadius:Number; var segment:QuadraticBezierSegment; for (var i:int = 0; i < numControlPoints; i++) { var startX:Number = centerX + radius * Math.cos(arcLength * i); var startY:Number = centerY + radius * Math.sin(arcLength * i); //control radius formula //where does it come from, why does it work? controlRadius = radius / Math.cos(arcLength * .5); //the control point is plotted halfway between the arcLength and uses the control radius var controlX:Number = centerX + controlRadius * Math.cos(arcLength * (i + 1) - arcLength * .5); var controlY:Number = centerY + controlRadius * Math.sin(arcLength * (i + 1) - arcLength * .5); var endX:Number = centerX + radius * Math.cos(arcLength * (i + 1)); var endY:Number = centerY + radius * Math.sin(arcLength * (i + 1)); segment = new QuadraticBezierSegment(new Point(startX, startY), new Point(controlX, controlY), new Point(endX, endY)); segments.push(segment); } return segments; }

• Display image background fully for last repeat in a div

  - by Stiggler

  I have a 700x300 background repeating seamlessly under the main content-div. Now I'd like to attach a div at the bottom of the content-div, containing a continuation-to-end of the background image, connecting seamlessly with the background above it. Due to the nature of the pattern, unless the full 300px height of the background image is visible in the last repeat of the content-div's backround, the background in the div below won't seamlessly connect. Basically, I need the content div's height to be a multiple of 300px under all circumstances. What's a good approach to this sort of problem? I've tried resizing the content-div on loading the page, but this only works as long as the content div doesn't contain any resizing, dynamic content, which is not my case: function adjustContentHeight() { // Setting content div's height to nearest upper multiple of column backgrounds height, // forcing it not to be cut-off when repeated. var contentBgHeight = 300; var contentHeight = $("#content").height(); var adjustedHeight = Math.ceil(contentHeight / contentBgHeight); $("#content").height(adjustedHeight * contentBgHeight); } $(document).ready(adjustContentHeight); What I'm looking for there is a way to respond to a div resizing event, but there doesn't seem to be such a thing. Also, please assume I have no access to the JS controlling the resizing of content in the content-div, though this is potentially a way of solving the problem. Another potential solution I was thinking off was to offset the background image in the bottom div by a certain amount depending on the height of the content-div. Again, the missing piece seems to be the ability to respond to a resize event.

• Custom control doesn't fire validation

  - by Ed Woodcock

  I've written a custom ASP.net control that descends from LinkButton and overrides the Render() method. I'm using it to replace ImageButtons in the site I'm working on so we don't have to have an image for each button. This control works fine, does the required post-backs etc., however it doesn't fire the validators in its validation group. This is obviously an issue. The code for the control is (condensed) as follows: using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; public class CustomButton : LinkButton { public string SpanCssClass { get; set; } protected override void Render(HtmlTextWriter writer) { if (!Visible) { return; } writer.AddAttribute(HtmlTextWriterAttribute.Name, UniqueID); writer.AddAttribute(HtmlTextWriterAttribute.Id, ClientID); writer.AddAttribute(HtmlTextWriterAttribute.Class, CssClass); string postback = string.IsNullOrEmpty(OnClientClick) ? "javascript:__doPostBack('" + UniqueID + "','');" : OnClientClick; writer.AddAttribute(HtmlTextWriterAttribute.Href, postback); writer.RenderBeginTag(HtmlTextWriterTag.A); writer.AddAttribute(HtmlTextWriterAttribute.Class, SpanCssClass); writer.RenderBeginTag(HtmlTextWriterTag.Span); writer.Write(Text); writer.RenderEndTag(); writer.RenderEndTag(); } } Does anyone know why this would not be causing the validators to fire? I was under the impression that leaving all the other methods in LinkButton un-overridden would leave all the other functionality the same!

• Programmatically creating a clickable area on an image.

  - by Thomas Stock

  Hi, I'm trying to create "imagemaps" on an image in wpf using codebehind. See the following XML: <Button Type="Area"> <Point X="100" Y="100"></Point> <Point X="100" Y="200"></Point> <Point X="200" Y="200"></Point> <Point X="200" Y="100"></Point> <Point X="150" Y="150"></Point> </Button> I'm trying to translate this to a button on a certain image in my WPF app. I've already did a part of this, but I'm stuck at setting the Polygon as the button's "template": private Button GetAreaButton(XElement buttonNode) { // get points PointCollection buttonPointCollection = new PointCollection(); foreach (var pointNode in buttonNode.Elements("Point")) { buttonPointCollection.Add(new Point((int)pointNode.Attribute("X"), (int)pointNode.Attribute("Y"))); } // create polygon Polygon myPolygon = new Polygon(); myPolygon.Points = buttonPointCollection; myPolygon.Stroke = Brushes.Yellow; myPolygon.StrokeThickness = 2; // create button based on polygon Button button = new Button(); ????? } I'm also unsure on how to add/remove this button to/from my image, but I'm looking into that. Any help is appreciated.

• UIPickerView crashing when switching segemented control

  - by Mattog1456

  Hello, I have four NSDictionaries that I would like to use to populate a pickerview depending on a segemented control. With the code I have, the first segmented control/pickerview works fine but when I switch to the second segment the picker view only loads part of the second dictionary, that is it loads the same number of rows as it counted in the first dictionary. When I change the segmented control to the third or fourth segment it simply crashes with a sigabrt error indicating that it cannot index item43 when only 27 exist. This I suspect stems from a UItextfield population based on the upickerview row and object. I think the problem is with the way I have the data source and delegate set up. #pragma mark - #pragma mark UIPickerViewDelegate - (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component { if ([wine selectedSegmentIndex] == 0) { return [robskeys objectAtIndex:row]; } if ([wine selectedSegmentIndex] == 1) { return [esabskeys objectAtIndex:row]; } if ([wine selectedSegmentIndex] == 2) { return [lebskeys objectAtIndex:row]; } else if ([wine selectedSegmentIndex] == 3) { return [sbskeys objectAtIndex:row]; } return @"Unknown title"; } #pragma mark - #pragma mark UIPickerViewDataSource - (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView { return 1; } - (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component { if ([wine selectedSegmentIndex] == 0) { return robskeys.count; } if ([wine selectedSegmentIndex] == 1) { return esabskeys.count; } if ([wine selectedSegmentIndex] == 2) { return lebskeys.count; } else if ([wine selectedSegmentIndex] == 3) { return sbskeys.count; } return 1; } #pragma mark - Any help would be much appreciated Thank you

• Arrow keys and changing control's focus hang the application

  - by sthay

  I have a usercontrol that contains a FlowLayoutPanel (topdown flow) with a bunch of radiobuttons. The control exposes a CheckedChanged event that fires whenever one of the radiobuttons's check changed. My form contains the usercontrol and a textbox. I subscribe the usercontrol's CheckedChanged event and depending on which radiobutton gets checked, I either disable the textbox or put a focus inside the textbox. All this works fine with mouseclick when changing the radiobutton's check state. However, this will hang indefinitely when using the arrow keys. I don't understand why the difference. The following are steps to reproduce the behavior I'm seeing: Create a usercontrol and drop a FlowLayoutPanel control and set its FlowDirection = TopDown. Then add two radiobuttons to the FlowLayoutPanel. Provide an event handler in the usercontrol public event EventHandler CheckedChanged { add { radioButton2.CheckedChanged += value; } remove { radioButton2.CheckedChanged -= value; } } Create a windows form and drop the above user control. Add a textbox and set Enabled to False. Subscribe to the usercontrol's CheckedChanged event as follows private void userControl11_CheckedChanged(object sender, EventArgs e) { textBox1.Select(); } Run. Notice that if you use the mouse to click between the radiobuttons, thing works fine; but it will crash if you use the up/down arrow keys.

• User control loosing its contents when loaded programatically

  - by Phil

  I have a usercontrol which contains 2 repeaters and the code to populate them with data. If i manually insert this into the page then it works correctly, the repeaters populate etc. If I load it programatically using this method; 1) add class name to user control ClassName="ContentModule" 2) reference this in the default.aspx <%@ Reference Control="~/modules/content.ascx" %> 3) Add the code to my codebehind page_load to do the loading; Private loadmodule As ASP.ContentModule Try If themodule = "content" Then loadmodule = CType(LoadControl("~\Modules\Content.ascx"), ASP.ContentModule) Modulecontainer.Controls.Add(loadmodule) End If Catch ex As Exception Response.Write(ex.ToString & "<br />") End Try Nothing from within the usercontrol is loaded to the page. Although if I add some static text i.e "TEST" to the top of the usercontrol this is displayed ok on the default.aspx page. This makes me think that the control is loaded ok, but there is something in the way I have loaded it that is causing the contents to not properly execute. Very frustrating this one! Any help greatly appreciated!

• WPF ContextMenu bind some property to another property of the same control

  - by bebicasoft

  I have a ContextMenu and a ColumnHeaderStyle defined in Window.Resource section witch i use-it to a DataGrid ColumnHeader. My code is something like this: <ContextMenu x:Key="cm_columnHeaderMenu"/> <Style x:Key="DefaultColumnHeaderStyle" TargetType="{x:Type DataGridColumnHeader}"> <Setter Property="ContextMenu" Value="{StaticResource cm_columnHeaderMenu}" /> </Style> <DataGrid Grid.Column="2" Grid.Row="1" x:Name="dgridFiles" IsReadOnly="True" ColumnHeaderStyle="{StaticResource DefaultColumnHeaderStyle}"> I want to know if I can (and if the answer it true, then HOW I could do it) bind the ContextMenu Visibility property to same control ContextMenu Items.Count>0 property. Initially based on some other treeView control selections made there shoud be no items in the context menu, but i wish to add dinamically items in ContextMenu based on selection in treeView. This part is done, the context has those items. On some selections there are no-items, but still on the grid it appears an empty ContextMenu. So I believe the easiest part it would be to bind the Visibility to Items.Count property of the same control. Sorry if my english is not good enought, I'll try to explain better if i didnt make clear 1st time.

• Retain, reuse, release?

  - by Typeoneerror

  I've got a series of buttons that each use a different image. Can I reuse a retained variable like this below: // set images UIImage *image = [[dice1 backgroundImageForState:UIControlStateHighlighted] retain]; [dice1 setBackgroundImage:image forState:(UIControlStateHighlighted|UIControlStateSelected)]; image = [dice2 backgroundImageForState:UIControlStateHighlighted]; [dice2 setBackgroundImage:image forState:(UIControlStateHighlighted|UIControlStateSelected)]; image = [dice3 backgroundImageForState:UIControlStateHighlighted]; [dice3 setBackgroundImage:image forState:(UIControlStateHighlighted|UIControlStateSelected)]; image = [dice4 backgroundImageForState:UIControlStateHighlighted]; [dice4 setBackgroundImage:image forState:(UIControlStateHighlighted|UIControlStateSelected)]; image = [dice5 backgroundImageForState:UIControlStateHighlighted]; [dice5 setBackgroundImage:image forState:(UIControlStateHighlighted|UIControlStateSelected)]; image = [dice6 backgroundImageForState:UIControlStateHighlighted]; [dice6 setBackgroundImage:image forState:(UIControlStateHighlighted|UIControlStateSelected)]; [image release]; or do I need to create a new UIImage for each image passed to each button's setBackgroundImage: like so: // set images UIImage *image1 = [dice1 backgroundImageForState:UIControlStateHighlighted]; [dice1 setBackgroundImage:image1 forState:(UIControlStateHighlighted|UIControlStateSelected)]; UIImage *image2 = [dice2 backgroundImageForState:UIControlStateHighlighted]; [dice2 setBackgroundImage:image forState:(UIControlStateHighlighted|UIControlStateSelected)]; and rely on autorelease rather than a retained UIImage. I'm not sure if assigning the image to a different UIImage would effect the retain count.

• XBAP Browser Control - Invoking Click event of the html Input type button

  - by maharaj

  Hi, Here is what I have. 1.XBAP application with WPF Browser control, hosted on Page1.xaml 2.XBAP in Full Trust, certificate installed in client browser 3.Once the XBAP loaded, the browser control is navigated to some third party site. 4.We are using MVVM for XAML stuff So, when a certain page is loaded, I attach click event handler to the input button with id="submit" on the html page displayed in the browser control (used the code similar to whats in this URL http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/a4f0e4d0-78bf-44c5-a3fe-8faf2e7a0568/). It works just fine as long as I dont make a wcf web service call in my ViewModel, before or after I attach this event hander. Idea is to invoke the click event for the html button and grab the data from the html page before calling the webservice to save data from the page. Here is the issue: When I make the wcf webservice call (sync or async, it doesnt matter) the click event doesnt happen but if I comment out the the code for wcf service call the click event of the html input of type button gets invoked. Any help would be appreciated. Thanks, Salil

• ASP.NET Login Control rejects users who exist

  - by rsteckly

  Hi, I'm having some trouble with the ASP.NET 2.0 Login Control. I've setup a database with the aspI.net regsql tool. I've checked the application name. It is set to "/". The application can access the SQL Server. In fact, when I go to retrieve the password, it will even send me the password. Despite this, the login control continues to reject logins. I added this to the web.config: <membership defaultProvider="AspNetSqlProvider"> <providers> <clear/> <add name="AspNetSqlProvider" connectionStringName="LocalSqlServer" applicationName="/" type="System.Web.Security.SqlMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/> </providers> And I added the following to my connection strings: <remove name="LocalSqlServer" /> <add name="LocalSqlServer" connectionString="Data Source=IDC-4\EXCALIBUR;Initial Catalog=allied_nr;Integrated Security=True;Asynchronous Processing=True"/> (Note the "remove name" is to get rid of the default connection string in the App_Data directory.) Why won't the login control authenticate users?

• [iText] Inserting Image onCloseDocument

  - by David

  I'm trying to insert an image in the footer of my document using iText's onCloseDocument event. I have the following code: public void onCloseDocument(PdfWriter writer, Document document) { PdfContentByte pdfByte = writer.getDirectContent(); try { // logo is a non-null global variable Image theImage = new Jpeg(logo); pdfByte.addImage(theImage, 400.0f, 0.0f, 0.0f, 400.0f, 0.0f, 0.0f); } catch (Exception e) { e.printStackTrace(); } } The code throws no exceptions, but it also fails to insert the image. This identical code is used onOpenDocument to insert the same logo. The only difference between the two methods are the coordinates in pdfByte.addImage. However, I've tried quite a few different coordinations in onCloseDocument and none of them appear anywhere in my document. Is there any troubleshooting technique for detecting content which is displayed off-page in a PDF? If not, can anyone see the problem with my onCloseDocument method? Edit: As a followup, it seems that onDocumentClose puts its content on page document.length() + 1 (according to its API). However, I don't know how to change the page number back to document.length() and place my logo on the last page.

  Hello Everyone!! Hope You all are fine and also in one of your best of moods!! Hope You all are Enjoying iPhone development. I herewith one issue that i am not able to solve, may be i don't know the depth concept of iPhone. So Its my humble requet to you to guide me or suggest or share your ideas. I do find an issue with getting an image from Bytes array. I am calling a webservice which returns an image in form of Bytes Array as response. I have Converted this bytes array in to form of NSData, Now i have NSData, But When i Try to get an image from this NSData, It shows nil. I Did lots of R&D and Find one suggestion to use base64 encoder, But unfortunately because of not proper guidance I was not able to Implement that. I was also suggested to use OPenSSL Library for base64 from url http://www.cocoadev.com/index.pl?BaseSixtyFour But again i was not able to include #include #include these two files. as in Newer Version of SDK 3.X family Apple has depreciated those (as i guess). So Now i need help from you guys. kindly help me if you have solution or if you know the steps to solve these. Looking Forwards. Regards, Arun Thakkar

• Stop image from tiling

  I have a procedure: procedure DrawSolidHexImage(Target: TCanvas; { Canvas to draw hex on } Fillstyle : TBrushStyle; { How to fill the hex } Fillcolor : TColor; { Color to fill it } fillimage : Tbitmap; { Image to show} Linestyle : TPenStyle; { What kind of lines } LineColor : Tcolor; { What color for lines } x,y,radius: integer; { Position and size of Hex } button : boolean); { Make hexes look like buttons? } When I use this, the image is tiled to fill the area. Is there something I can add or must remove to make it not tile? Thus not repeating the image. Maybe make it center? The Code in which I use DrawSolidHexImage looks like: procedure THexMap.ImageAHex(ImageWanted : TBitmap; HexPatternWanted: TBrushStyle; MapLocation:TPoint); var p0:TPoint; begin if FHexMapOn and FDrawSolidMap and (not UseSavedMap) then begin with TempMap.canvas do p0 := ConvertCoords(Point(MapLocation.x,MapLocation.y),ptROWCOL); DrawSolidHexImage(TempMap.Canvas,HexPatternWanted,clGray, Imagewanted,psSolid,LineColor,p0.x,p0.y,hexradius,hex3d); Refresh; end; end;

• RSpec: Can't convert Image to String when using Nested Resource.

  I'm having trouble with and RSpec view test. I'm using nested resources and the model with a belongs_to association.

Any ideas on how I can narrow down what is going on here? One thing I tried was calling form_for directly from the example and I got a different error griping about lack of 'polymorphic_path' defined on Spec::Rails::Example::ViewExampleGroup::Subclass_4:0xblah. Not sure if that actually means anything.

• asp.net mvc stand alone ascx control how do i link (css and js) most efficiently

  - by Julian

  Hi, I need some advice. I have developed some asp.net mvc web pages. Each page has a master and some ascx controls (between 2 - 6) embedded into it a js and css file. Up to now every thing was fine. In order to improve modularity, flexibility and testability the ascx's are now expected to be able to work as stand alone controls. (Each ascx has also got its own css and js files in some cases it has another control inside it) In order to meet this requirement we call the controller with the relevant parameters and it returns the ascx (partial) directly to the browser without all of the other parts of the original page . In order to get it to display correctly (css) and act correctly (js/jquery) all of the relevant files need to be added (as links or scripts eg. href="<%= ResolveUrl(styleSheet)%>") to the user control. This is "contradicting" the concept of positioning the files at the most logical place (could be the master page for example). How can I overcome this problem? Keep in mind that this is relevant for each "control" ascx file. Any thoughts will be appreciated.

But because I need to add 30-40 images I need to wrap the above in a function (which returns a UIImageView) and then call it from a loop. This is my first attempt at creating the function -(UIImageView)wrapImageInView:(NSString *)imagePath { UIImage *image = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:imagePath ofType:nil]]; UIImageView *view = [[UIImageView alloc] initWithImage:image]; view.hidden = YES; } And then to invoke it I have the following so far, for simplicity I am only wrapping 3 images //Create an array and add elements to it NSMutableArray *anArray = [[NSMutableArray alloc] init]; [anArray addObject:@"image1.jpg"]; [anArray addObject:@"image2.jpg"]; [anArray addObject:@"image3.jpg"]; //Use a for each loop to iterate through the array for (NSString *s in anArray) { UIImageView *wrappedImgInView=[self wrapImage:s]; [containerView addSubview:wrappedImgInView]; NSLog(s); } //Release the array [anArray release]; I have 2 general questions 1-Is my approach correct?, ie following best practices, for what I am trying to do (load a multiple number of images(jpgs, pngs, etc.) and adding them to a container view) 2-For this to work properly with a large number of images, do I need to keep my array creation separate from my method invocation? Any other suggestions welcome!

• Changing url of background image

  - by João Pedro

  I'm doing this interface where I have a lot of buttons that are just a li with a background image like this #menu ul.icons li.nove { background-image:url(images/edit-menu/icons/undo.png); background-size:contain; display:block; margin-top:29px; } <ul class="icons"> <li class="um"></li> <li class="dois"></li> <li class="tres"></li> <li class="quatro"></li> <li class="cinco"></li> <li class="seis"></li> <li class="sete"></li> <li class="oito"></li> <li class="nove"></li> <li class="dez"></li> </ul> I need to create a code where I change the background image of the button when the user clicks it, to show that button its activated, I just need to change url(images/edit-menu/icons/ to url(images/edit-menu/select/ and keep the same filename. I need a way to do this dynamically so I won't have to do it for each of the 10 buttons. Hope I was clear, thanks in advance

• How can I rotate an image using Java/Swing and then set its origin to 0,0?

  - by JT

  I'm able to rotate an image that has been added to a JLabel. The only problem is that if the height and width are not equal, the rotated image will no longer appear at the JLabel's origin (0,0). Here's what I'm doing. I've also tried using AffineTransform and rotating the image itself, but with the same results. Graphics2D g2d = (Graphics2D)g; g2d.rotate(Math.toRadians(90), image.getWidth()/2, image.getHeight()/2); super.paintComponent(g2d); If I have an image whose width is greater than its height, rotating that image using this method and then painting it will result in the image being painted vertically above the point 0,0, and horizontally to the right of the point 0,0.
