  • Inverted colours in tiff to PDF conversion

    - by spiderdijon
    I'm sure I'm making some kind of silly mistake here, but when converting a tiff file to PDF, the colours become reversed. I can't figure out why. Here's my code: PdfWriter writer = PdfWriter.GetInstance(document, new FileStream("Image.pdf", FileMode.Create)); System.Drawing.Bitmap bm = new System.Drawing.Bitmap(@"C:\Temp\338814-00.tif"); int total = bm.GetFrameCount(FrameDimension.Page); document.Open(); PdfContentByte cb = writer.DirectContent; for (int k = 0; k < total; ++k) { bm.SelectActiveFrame(FrameDimension.Page, k); MemoryStream ms = new MemoryStream(); bm.Save(ms, ImageFormat.Tiff); Image img = Image.GetInstance(ms.ToArray()); img.ScalePercent(72f / (float)img.DpiX * 100); img.SetAbsolutePosition(0, 0); cb.AddImage(img); document.NewPage(); } document.Close(); Thanks.

  • function in php for displaying a menu

    - by Stanislas Piotrowski
    I met some trouble with a function I have written. In fact I have an array in which I have different custom values. I would like to display the result of that, so here is my function function getAccess($var){ $data=mysql_fetch_array(mysql_query("SELECT * FROM `acces` WHERE `id`='.$var.'")); return $data; } getAccess($_SESSION['id']); $paramAcces = array( 'comptesfinanciers' => array( 'libelle' => 'COMPTES FINANCIERS', 'acces' => $data['comptesfinanciers'], 'lien' => 'financier', 'image' => 'images/finances.png' ) ); I have done a var_dump of $paramAcces which return array(1) { ["comptesfinanciers"]=> array(4) { ["libelle"]=> string(18) "COMPTES FINANCIERS" ["acces"]=> NULL ["lien"]=> string(9) "financier" ["image"]=> string(19) "images/finances.png" } } (that are the ecpected values). Here is the function for displaying what is in the array /** * AFFICHAGE DE LA SECTION PARAMETRES SUR LA PAGE D'ACCUEIL */ function affichParam($paramAccees){ echo '<ul class="getcash-vmenu"><li><a href="index.php?p='.$paramAccees['lien'].'" class="active"><span class="t"><img src="'.$paramAccees['image'].'"> '.$paramAccees['libelle'].'</span></a></li></ul>'; } The trouble is that actualy it return to me an empty line. I really do not know what I'm wrong doin: I call the function like that: <?php affichParam($paramAccees) ?> In a second time I will add more value, so I think I will have to do a for each loop or something like that. But actualy I just would like to display the first record. Any kind of help will be much apprecitaed

  • PHP not obeying my defined ETags

    - by Sam Bisbee
    What I'm doing I'm pulling an image from the database and sending it to the browser with all the proper headers - the image displays fine. I also send an ETag header, using the SHA1 of the image's content as the tag. The images are getting called semi regularly, so caching is a bit of an issue (won't kill the site, but nice to have). The Problem $_SERVER['HTTP_IF_NONE_MATCH'] is not available to me. As far as I can tell, this is because of PHP's "disobey the cache controls" life style. I can't mess with the session cache limiter, because I don't have access. But, even if I did have access, I wouldn't want to touch it: 99% of the site is under WordPress. The Environment PHP 4 (don't ask) Apache 2.2 WordPress The images live in the database (largeblog), which I can't change. Any guidance, tip/tricks, etc. would be helpful. I don't have much room to change the environmental/structural stuff. Cheers.

  • Crazy TableView (Or more likely me being just a jerk) ;-)

    - by Miky Mike
    Hi guy, I'm going crazy with all that objective C. I went to bed at 1.30 pm today, spending the night on my app but I love it... Well that's not the point anyway... My question is .... I have a table view which evaluates a statement when it displays its data : it goes like this : - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"CustomCell"; cell = ((MainCell *)[self.tableView dequeueReusableCellWithIdentifier:CellIdentifier]); if (cell == nil) { [[NSBundle mainBundle] loadNibNamed:@"MainCell" owner:self options:nil]; } Entry *entry = [fetchedResultsController objectAtIndexPath:indexPath]; cell.topLabel.text = [@"* " stringByAppendingString: entry.entryname]; cell.bottomLabel.text = entry.textbody; if ([entry.active boolValue] == YES) { cell.cellImageView.image = [UIImage imageNamed:@"check.png"]; } else { cell.cellImageView.image = nil; cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton; } return cell; } The problem is that the first time it displays the data, the conditions are met when I scroll down the tableview but when I scroll up, sometimes, I get my "check.png" image and the accessory as well, which is not possible normally. Am I going crazy or is it the tableview ? Could you help me with that please, I can't figure out why it doesn't work... :-(( Thanks a lot in advance. Mike

  • Error handling in PHP

    - by Industrial
    Hi guys, We're building a PHP app based on Good old MVC (codeigniter framework) and have run into trouble with a massive chained action that consists of multiple model calls, that together is a part of a big transaction to the database. We want to be able to do a list of actions and get a status report of each one back from the function, whatever the outcome is. Our first initial idea was to utilize the exceptions of PHP5, but since we want to also need status messages that doesnt break the execution of the script, this was our solution that we came up with. It goes a little something like this: $sku = $this->addSku( $name ); if ($sku === false) { $status[] = 'Something gone terrible wrong'; $this->db->trans_rollback(); return $status; } $image= $this->addImage( $filename); if ($image=== false) { $error[] = 'Image could not be uploaded, check filesize'; $this->db->trans_rollback(); return $status; } Our controller looks like this: $var = $this->products->addProductGroup($array); if (is_array($var)) { foreach ($var as $error) { echo $error . '<br />'; } } It appears to be a very fragile solution to do what we need, but it's neither scalable, neither effective when compared to pure PHP exceptions for instance. Is this really the way that this kind of stuff generally is handled in MVC based apps? Thanks!

  • Can't set Visible attribute in ASP.NET Panels

    - by RichW
    I am having trouble with visible attribute of an ASP.NET Panel control. I have a page that calls a database table and returns the results in a datagrid. Requirements If some of the returned values are null I need to hide the image that's next to it. I am using a Panel to determine whether to hide or show the image but am having trouble with the statement: visible='<%# Eval("addr1") <> DBNull.Value %>' I have tried these as well: visible='<%# Eval("addr1") <> DBNull.Value %>' visible='<%# IIf(Eval("addr1") Is DbNull.Value, "False","True") %>' Code is below: <asp:TemplateField > <ItemTemplate> <%# Eval("Name")%> <p> <asp:Panel runat="server" ID="Panel1" visible='<%# Eval("addr1") <> DBNull.Value %>'> <asp:Image Id="imgHouse" runat="server" AlternateText="Address" SkinId="imgHouse"/> </asp:Panel> <%# Eval("addr1") %><p> </ItemTemplate> </asp:TemplateField> What am I doing wrong? Edit If I use visible='<%# IIf(Eval("addr1") Is DbNull.Value, "False","True") %>' I get the following error: Compiler Error Message: CS1026: ) expected

  • FindControl in DataList Edit Mode

    - by Doug
    As a new .net/C# web begginner, I always get tripped up when I try to use FindControl. Blam -flat on my face. Here is my current FindControl problem: I have an .aspx page and Form, then ajax updatePanel, inside it there is my DataList (DataList1) that has an EditItemTemplate: that has the following: <EditItemTemplate> <asp:Label ID="thumbnailUploadLabel" runat="server" text="Upload a new thumbnail image:"/><br /> <asp:FileUpload ID="thumbnailImageUpload" runat="server" /> <asp:Button ID="thunbnailImageUploadButton" runat="server" Text="Upload Now" OnClick="thumbnailUpload"/><br /> </EditItemTemplate> In my C# code behind I have the OnClick code for the fileUpload object: protected void thumbnailUpload(object s, EventArgs e) { if (thumbnailImageUpload.HasFile) { //get name of the file & upload string imageName = thumbnailImageUpload.FileName; thumbnailImageUpload.SaveAs(MapPath("../../images/merch_sm/" + imageName)); //let'em know that it worked (or didn't) thumbnailUploadLabel.Text = "Image " + imageName + "has been uploaded."; } else { thumbnailUploadLabel.Text = "Please choose a thumbnail image to upload."; } So of course I'm getting "Object reference not set to an instance of an object" for the FileUpload and the Label. What is the correct syntax to find these controls, before dealing with them in the OnClick event? The only way Ive used FindControl is something like: label thumbnailUploadLabel = DataList1.FindControl("thumbnailUploadLabel") as Label; But of course this is throwing the "Object reference not set to an instance of an object" error. Any help is very much appreciated. (I've also seen the 'recursive' code out there that is supposed to make using FindControl easier. Ha! I'm so green at C# that I don't even know how to incorporate those into my project.) Thanks to all for taking a look at this.

  • Trying to draw 2 objects on screen and store the selected item names in an array

    - by thefonso
    Ok...this is a homework question, here is what i'm asked to do.... "Allow the user to draw two Shapes, which when instantiated, get put into the array myShapes...(store the shapes in the createShape() method." I want to know if I'm going in the right direction. Do I need to modify only Model.java or GUIDemo.java as well? Am I sufficient in thinking of only storing the values for the array via a loop inside my createShape() method? How do I go a bout checking to see if things work so far. There are many steps for this homework project after this one but i'm stuck here. Please point me in the right direction.

  • Sending jpegs by tcp socket...sometimes incomplete.

    - by Guy
    Vb.net Hi I've been working on a project for months now (vb 2008 express). There is one final problem which I can't solve. I need to send images to a client from a 'server'(listener). The code below works most of the time but sometimes the image is incomplete. I believe this might be something to do with the tcp packet sizes varying, maybe limited by how busy it is out there on the net. I have seen examples of code that splits the image into chunks and sends them out, but I can't get them to work maybe because I'm using a different vb version. The pictures to be sent are small 20k max. Any working code examples would be wonderful. I have been experimenting and failing with this final hurdle for weeks. Thanks in anticipation. Client----- Sub GetPic() '------- Connect to Server ClientSocket = New Socket(AddressFamily.InterNetwork, SocketType.Stream, _ ProtocolType.Tcp) ClientSocket.Connect(Epoint) '------- Send Picture Request Dim Bytes() As Byte = System.Text.ASCIIEncoding.ASCII.GetBytes("Send Picture") ClientSocket.Send(Bytes, Bytes.Length, SocketFlags.None) '------- Receive Response Dim RecvBuffer(20000) As Byte Dim Numbytes As Integer Numbytes = ClientSocket.Receive(RecvBuffer) Dim Darray(Numbytes) As Byte Buffer.BlockCopy(RecvBuffer, 0, Darray, 0, Numbytes) '------- Close Connection ClientSocket.Shutdown(SocketShutdown.Both) ClientSocket.Close() '------- Dim MStrm = New MemoryStream(Darray) Picture = Image.FromStream(MStrm) End Sub Listener----- 'Threaded from a listener Sub ClientThread(ByVal Client As TcpClient) Dim MStrm As New MemoryStream Dim Rbuffer(1024) As Byte Dim Tbyte As Byte() Dim NStrm As NetworkStream = Client.GetStream() Dim I As Integer = NStrm.Read(Rbuffer, 0, Rbuffer.Length) Dim Incoming As String = System.Text.Encoding.ASCII.GetString(Rbuffer, 0, I) If Incoming = "Send Picture" then Picture Save(MStrm, Picture.RawFormat) Tbyte = MStrm.ToArray NStrm.Write(Tbyte, 0, Tbyte.Length) End if Client.Close() End Sub

  • How to- NSAttributedString to CGImageRef

    - by kroko
    Hello! I'm writing a QuickLook plugin. Well, everything works. Just want to try it make better ;). Thus the question. Here is a function that returns thumbnail image and that I'm using now. QLThumbnailRequestSetImageWithData( QLThumbnailRequestRef thumbnail, CFDataRef data, CFDictionaryRef properties); ); http://developer.apple.com/mac/library/documentation/UserExperience/Reference/QLThumbnailRequest_Ref/Reference/reference.html#//apple_ref/c/func/QLThumbnailRequestSetImageWithData Right now I'm creating a TIFF - encapsulated it into NSData. An example // Setting CFDataRef CGSize thumbnailMaxSize = QLThumbnailRequestGetMaximumSize(thumbnail); NSMutableAttributedString *attributedString = [[[NSMutableAttributedString alloc] initWithString:@"dummy" attributes:[NSDictionary dictionaryWithObjectsAndKeys: [NSFont fontWithName:@"Monaco" size:10], NSFontAttributeName, [NSColor colorWithCalibratedRed:0.0 green:0.0 blue:0.0 alpha:1.0], NSForegroundColorAttributeName, nil] ] autorelease]; NSImage *thumbnailImage = [[[NSImage alloc] initWithSize:NSMakeSize(thumbnailMaxSize.width, thumbnailMaxSize.height)] autorelease]; [thumbnailImage lockFocus]; [[NSColor whiteColor] set]; NSRectFill(NSMakeRect(0, 0, thumbnailMaxSize.width, thumbnailMaxSize.height)); [attributedString drawInRect:NSMakeRect(0, 0, thumbnailMaxSize.width, thumbnailMaxSize.height)]; [thumbnailImage unlockFocus]; (CFDataRef)[thumbnailImage TIFFRepresentation]; // This is data // Setting CFDictionaryRef (CFDictionaryRef)[NSDictionary dictionaryWithObjectsAndKeys:@"kUTTypeTIFF", (NSString *)kCGImageSourceTypeIdentifierHint, nil ]; // this is properties However QuickLook provides another function to return thumbnail image, namely QLThumbnailRequestSetImage( QLThumbnailRequestRef thumbnail, CGImageRef image, CFDictionaryRef properties); ); http://developer.apple.com/mac/library/documentation/UserExperience/Reference/QLThumbnailRequest_Ref/Reference/reference.html#//apple_ref/c/func/QLThumbnailRequestSetImage I have a feeling that passing CGImage to the QL instead of TIFF data would help in speeding things up. However- I have never worked with CG context before. I know, the documentation is there :), but anyways- could anyone give an example how to turn that NSAttributed string into CGImageRef. An example is worth 10 times reading the documentation ;) Any help appreciated. Thanks in advance!

  • Why won't my styles show in a Dynamics CRM 4 IFRAME?

    - by Dan Crowther
    I have created a web page (ASP.NET) that includes a stylesheet to mimic Dynamics CRM styles. This is to be used in a CRM IFRAME (within a form). The stylesheet is referenced as follows: <head id="Head1" runat="server"> <link href="Styles.css" rel="stylesheet" type="text/css" /> </head> When I load the page in Visual Studio, all is well. When I load it in CRM, none of the styles are shown and no images are displayed. If I browse directly to the image, I get a 404 error. However, the pages function correctly. I have set read permissions for "Everyone" on the server to see if that was causing a problem but it didn't help. I also tried putting a plain HTML page in the folder and that won't load either - again a 404. The page is installed in the ISV folder ..../isv/MyProject. Can anyone help? EDIT This is on a multi-tenancy system. On my test company (testcompany) if I browse to http://crm/testcompany/isv/MyProject/MyPage.aspx, the page is loaded (without styles and images). If I browse to http://crm/testcompany/isv/MyProject/TestImage.gif, the image is not shown. If I browse to http://crm/isv/MyProject/TestImage.gif, the image is shown. Does this suggest a problem with the server setup and the way CRM messes around with virtual directories?

  • How to genrate a monochrome bit mask for a 32bit bitmap

    - by Mordachai
    Under Win32, it is a common technique to generate a monochrome bitmask from a bitmap for transparency use by doing the following: SetBkColor(hdcSource, clrTransparency); VERIFY(BitBlt(hdcMask, 0, 0, bm.bmWidth, bm.bmHeight, hdcSource, 0, 0, SRCCOPY)); This assumes that hdcSource is a memory DC holding the source image, and hdcMask is a memory DC holding a monochrome bitmap of the same size (so both are 32x32, but the source is 4 bit color, while the target is 1bit monochrome). However, this seems to fail for me when the source is 32 bit color + alpha. Instead of getting a monochrome bitmap in hdcMask, I get a mask that is all black. No bits get set to white (1). Whereas this works for the 4bit color source. My search-foo is failing, as I cannot seem to find any references to this particular problem. I have isolated that this is indeed the issue in my code: i.e. if I use a source bitmap that is 16 color (4bit), it works; if I use a 32 bit image, it produces the all-black mask. Is there an alternate method I should be using in the case of 32 bit color images? Is there an issue with the alpha channel that overrides the normal behavior of the above technique? Thanks for any help you may have to offer! ADDENDUM: I am still unable to find a technique that creates a valid monochrome bitmap for my GDI+ produced source bitmap. I have somewhat alleviated my particular issue by simply not generating a monochrome bitmask at all, and instead I'm using TransparentBlt(), which seems to get it right (but I don't know what they're doing internally that's any different that allows them to correctly mask the image). It might be useful to have a really good, working function: HBITMAP CreateTransparencyMask(HDC hdc, HBITMAP hSource, COLORREF crTransparency); Where it always creates a valid transparency mask, regardless of the color depth of hSource. Ideas?

  • java applet stops running on exceptions

    - by Marius
    I've developed a simple applet that imports an image from the clipboard. When i run the class file from NetBeans, everything works fine. But when i try to run it as an applet ... it gives me lots of errors in the java console and does not run ... - The applet is signed - There is a static method in one class, called getImageFromClipboard(). When the applet runs, it calls this method. - getImageFromClipboard() method has a try-catch block and suppresses all errors. It simply returns either a BufferedImage or null. - When applet runs, it does some visual adjustments before calling getImageFromClipboard() Now the scenario is as follows: the class from netbeans runs, fails to import the image and adjusts the interface accordingly (displays an error in a label) But when i run it in a browser, java console is filled with errors and nothing after the getImageFromClipboard() line works. Although the applet itself loads and does everything it's supposed do do before importing the image. So why am i getting errors if i accept the certificate and all of the possible errors are in try-catch blocks? None of this code should throw any exceptions. Any ideas why this is happening? Or do you need to see the errors to tell? UPDATE I've managed to find out the problem myself. The class that i'm using is not in the jar file :( How do i add it in? I'm using "add jar folder" in netbeans on the libraries package to import it but it does not seem to get copied to the jar.

  • loading custom view using loadNibNamed showing memory leaks

    - by user307550
    I have a number of custom table cells and views that I built using interface builder In interface builder, everything is set up similarly. There is a table cell and a couple other UILabels and a background image Object owner if the nib is NSObject Class for the table cell is the name of the class for my table cell Here is how I create the table cell in my code: SectionedSwitchTableCell *cell = nil; NSArray *nibs = [[NSBundle mainBundle] loadNibNamed:kSectionedSwitchTableCellIdentifier owner:owner options:nil]; for(id currentObject in nibs) { if([currentObject isKindOfClass:[SectionedSwitchTableCell class]]) { cell = (SectionedSwitchTableCell *)currentObject; break; } } return cell; For my custom table headers I have this NSArray *nibs = [[NSBundle mainBundle] loadNibNamed:@"CustomTableHeader" owner:self options:nil]; for(id currentObject in nibs) { if([currentObject isKindOfClass:[CustomTableHeader class]]) { return header } } In my .h and .m files for the custom view, I have IBOutlet, @property set up for everything except for the background image UIImageView. Everything that has the IBOutlet and @property are also @synthesized and released in the .m file. Leaks is showing that I have memory leaks with CALayer when I create these custom view objects. Am I doing something wrong here when I create these custom view objects? I'm kind of tearing my hair out trying to figure out where these leaks are coming from. As a side note, I have a UIImageView background image defined in these custom views but I didn't define properties and IBOutlets in my .h and .m files. Defining them doesn't make a difference when I run it through Leaks but just wanted to confirm if I'm doing the right thing. Any input would be super helpful. Thanks :)

    After looking at questions like this it doesn't make sense that my __init__(self, parrent, id) would be throwing a unbound error? help? main.py import wx from customButton import customButton from wxPython.wx import * class MyFrame(wx.Frame): def __init__(self, parent, ID, title): wxFrame.__init__(self, parent, ID, title, wxDefaultPosition, wxSize(400, 400)) # Non-important code here... # This is the first declaration of the Button1 # This is also where the ERROR is thrown. # Omitting this line causes the window to execute # flawlessly. self.Button1 = customButton.__init__(self, parent, -1) # ... finishes in a basic wx.program style... customButton.py # I've included all of the code in the file # because have no idea where the bug/error happens import wx from wxPython.wx import * class Custom_Button(wx.PyControl): # The BMP's Over_bmp = None #wxEmptyBitmap(1,1,1) # When the mouse is over Norm_bmp = None #wxEmptyBitmap(1,1,1) # The normal BMP Push_bmp = None #wxEmptyBitmap(1,1,1) # The down BMP def __init__(self, parent, id, **kwargs): wx.PyControl.__init__(self,parent, id, **kwargs) # Set the BMP's to the ones given in the constructor #self.Over_bmp = wx.Bitmap(wx.Image(MOUSE_OVER_BMP, wx.BITMAP_TYPE_ANY).ConvertToBitmap()) #self.Norm_bmp = wx.Bitmap(wx.Image(NORM_BMP, wx.BITMAP_TYPE_ANY).ConvertToBitmap()) #self.Push_bmp = wx.Bitmap(wx.Image(PUSH_BMP, wx.BITMAP_TYPE_ANY).ConvertToBitmap()) #self.Pos_bmp = self.pos self.Bind(wx.EVT_LEFT_DOWN, self._onMouseDown) self.Bind(wx.EVT_LEFT_UP, self._onMouseUp) self.Bind(wx.EVT_LEAVE_WINDOW, self._onMouseLeave) self.Bind(wx.EVT_ENTER_WINDOW, self._onMouseEnter) self.Bind(wx.EVT_ERASE_BACKGROUND,self._onEraseBackground) self.Bind(wx.EVT_PAINT,self._onPaint) self._mouseIn = self._mouseDown = False def _onMouseEnter(self, event): self._mouseIn = True def _onMouseLeave(self, event): self._mouseIn = False def _onMouseDown(self, event): self._mouseDown = True def _onMouseUp(self, event): self._mouseDown = False self.sendButtonEvent() def sendButtonEvent(self): event = wx.CommandEvent(wx.wxEVT_COMMAND_BUTTON_CLICKED, self.GetId()) event.SetInt(0) event.SetEventObject(self) self.GetEventHandler().ProcessEvent(event) def _onEraseBackground(self,event): # reduce flicker pass def _onPaint(self, event): dc = wx.BufferedPaintDC(self) dc.SetFont(self.GetFont()) dc.SetBackground(wx.Brush(self.GetBackgroundColour())) dc.Clear() dc.DrawBitmap(self.Norm_bmp) # draw whatever you want to draw # draw glossy bitmaps e.g. dc.DrawBitmap if self._mouseIn: # If the Mouse is over the button dc.DrawBitmap(self, self.Mouse_over_bmp, self.Pos_bmp, useMask=False) if self._mouseDown: # If the Mouse clicks the button dc.DrawBitmap(self, self.Push_bmp, self.Pos_bmp, useMask=False)

  • Running resize2fs on /

    - by Paul Steckler
    I'm trying to resize an ext4 filesystem on a Fedora 11 box. Using fsdisk and lvm, I was able to grow the partition and logical volume containing the filesystem. When I try to run resize2fs on the device containing the filesystem (/dev/sda2 in this case), I get: "Device or resource busy while trying to open /dev/sda2, Couldn't find valid filesystem superblock" I've tried this from a rescue disk that doesn't have the filesystem mounted, no joy. Maybe resize2fs doesn't know about ext4?

  • Space Stuck between two Div Tags

    - by thatmaclad
    I've been working on a small blog form but have been having trouble with my Div tags. Whenever I create a second div tag to hold the Form a space has appeared between it and the previous Div tag. Is there anything wrong with my CSS? body { background-image: url(../images/body-bg.jpg); font-family: arial; } #header { background-image: url(../images/new-post-h.png); background-repeat: no-repeat; height: 124px; width: 850px; color: #ffffff; margin: 0em 0px; } #form-bg { background-image: url(../images/new-post-b.png); background-repeat: no-repeat; height: 500px; width: 850px; padding: 8px; margin: 0em 0px; } #new-form { height: 624px; width: 850; margin-left: auto; margin-right: auto; } Here is what keeps on happening: http://i40.tinypic.com/j623i8.jpg

  • Horizontal and vertical center text in html

    - by Christophe Herreman
    I have a div with a background image that needs to be centered horizontally and vertically. On top of that image, I also want to display a 1-line text, also centered horizontally and vertically. I managed to get the image centered, but the text is not centered vertically. I thought vertical-align:middle would do the trick. Here's the code I have: <div style="background: url('background.png') no-repeat center; width:100%; height:100%; text-align:center;"> <div style="color:#ffffff; text-align: center; vertical-align:middle;" > Some text here. </div> </div> Any ideas? Workaround: I actually got this to work by using a table. (I'll probably be cursed to hell by the HTML community.) Is there any significant reason not to use this btw? I'm still interested in the solution using divs though. <table width="100%" height="100%"> <tr> <td align="center" style="background: url('background.png') no-repeat center; color:#ffffff;">Some text here.</td> </tr> </table>
