  • Extra blank page when converting HTML to PDF using abcPDF

    - by ProfK
    I have an HTML report, with each print page contained by a <div class="page">. The page class is defined as width: 180mm; height: 250mm; page-break-after: always; background-position: centre top; background-image: url(Images/MainBanner.png); background-repeat: no-repeat; padding-top: 30mm; After making a few changes to my report content, when I call abcPDF to convert the report to PDF, suddenly I'm getting a blank page inserted after every real report page. I don't want to roll back the changes I've just made to remove this problem, so I'm hoping someone may know why the extra pages are being inserted.

  • How to resize WebView according to its content?

    - by Miraaj
    Hi all, I want to set simple html contents within a web view and then resize it according to its content. To set simple html contents within web view I used this code and it is working fine: [[myWebView mainFrame] loadHTMLString:webViewContents baseURL:baseURLFramed]; Right now, if content is more than its actual size then it appears in web view showing both vertical and horizontal scroller in it. I want to set some default width and manage height according to its content in a way so that neither horizontal nor vertical scroller appears. Can anyone suggest me some solution for it? Thanks, Miraaj

  • Print a bitmap without printing a sprite?

    - by Carlos Barbosa
    Following up from: http://stackoverflow.com/questions/3021557/as3-printing-problem-blanks-swf-after-print-or-cancel I am trying to comeup with a function to print without creating a sprite, because that's what it seems to be causing my problem: public function printScreen():void { var pJob:PrintJob = new PrintJob(); var options:PrintJobOptions = new PrintJobOptions(); options.printAsBitmap = true; var bitmapData:BitmapData = new BitmapData(root.width, root.height); bitmapData.draw(root); var printThis:Bitmap = new Bitmap(bitmapData); try { pJob.start(); pJob.addPage(printThis, null, options); pJob.send(); } catch(e:Error) { trace("Error Printing") } } This is coming up with an: Error: Description Implicit coercion of a value of type flash.display:Bitmap to an unrelated type flash.display:Sprite. So how do you print a bitmap without creating a Sprite?

  • How does Bitmap.Save(Stream, ImageFormat) format the data?

    - by Matt Jacobsen
    I have a non transparent, colour bitmap with length 2480 and width 3507. Using Bitmap.GetPixel(int x, int y) I am able to get the colour information of each pixel in the bitmap. If I squirt the bitmap into a byte[]: MemoryStream ms = new MemoryStream(); bmp.Save(ms, ImageFormat.Bmp); ms.Position = 0; byte[] bytes = ms.ToArray(); then I'd expect to have the same information, i.e. I can go to bytes[1000] and read the colour information for that pixel. It turns out that my array of bytes is larger than I anticipated. I thought I'd get an array with 2480 x 3507 = 8697360 elements. Instead I get an array with 8698438 elements - some sort of header I presume. In what format the bytes in my array stored? Is there a header 1078 bytes long followed by Alpha, Red, Green, Blue values for every byte element, or something else?

  • display:table killing me in IE

    - by subpixel
    I want to create horizontally-aligned table cells like the ones on this page. I've followed the instructions, and I've even copied the css and markup verbatim, but no matter what I do IE 8 renders my table cells as blocks (stacked on top of each other instead of aligned next to each other). css: <style type="text/css"> body.TableStyles { display: inline-table; border-spacing: 4px; } div.maketable p { display: table-cell; width: 20%; background-color: #cdf; padding: 4px; } </style> markup: <body class="TableStyles"> <div class="maketable"> <p>< prev</p> <p>next ></p> </div> </body>

  • css + first load bug + min-height

    - by Henry
    We forked an editor for upcoming release of our CMS. See: http://tinyurl.com/ylbtns2 The editor uses the css of the current template and loads an additional fix.css (inside the iframe) to override some rules: * { background-image: none !important; min-height: 0px !important; } #breadcrumbs, #content .sidebar, #footer, #header, #search_form { display: none; } #content { margin: 0px; width: 100%; } The problem: on first load the "min-height: 0px !important;" seems not to work - on second load the height of the editor iframe is 100px like it should be. Other rules like no background (fix.css) are working on first load and get overridden.

  • Force redraw as resizing NSTableColumn in NSTableView?

    - by Dov
    I've implemented - (CGFloat)tableView:(NSTableView *)tableView heightOfRow:(NSInteger)row in my NSTableView's delegate to resize the height of my table's rows as the width of the leftmost column changes. The problem is that only that column redraws during the resizing (and any column that slide into view during the resize). This results in the funky visual below after resizing. What I'd like is a way to tell the table view to completely redraw while the user is resizing a column. Right now the most I've been able to figure out is calling setNeedsDisplay after it that column finishes resizing.

  • Silverlight4 Printing Question

    - by hallgato.attila
    Hello everyone! I'm having a problem with printing. Is it possible to print a (customized) DataGrid which doesn't fit the page? a) Using a ViewBox to make it fit one page. My problem here is that I can get the PrintableArea.Width and PrintableArea.Height in the PrintPage EventHandler, from the PrintPageEventArgs, but in that Event Handler I can't set the size of an UIElement before it gets printed. b) Multiple pages. Is it possible somehow to print the whole DataGrid, even the parts which are not visible (don't fit the page) and to somehow make the PrintableArea only a part of the DataGrid?

  • WPF Custom Control with Image problem

    - by user311883
    Hi all, I am quite new to WPF/XAML and I am currently facing a problem. I have a solution with two projects in it, the first project is a Custom Control Library with a custom Window form control inside. The second project is a WPF application using my custom window form. All work fine except for the form Icon. In the WPF application project I set my window icon property to "/ProjectTwoNameSpace;component/Resources/Images/Film.ico", and in the WPF custom control I try to show that image that way : <Image Grid.Column="0" Margin="3" Width="27" Height="27"> <Image.Source> <BitmapImage UriSource="{Binding Path=Icon}" /> </Image.Source> </Image> But it doesn't work, I get a error at runtime saying that the property UriSource or StreamSource must be set for my tag. Anyone can help me ? I think it's jsut a WPF newbie problem ^^

  • Dynamic Spacer in ReportLab

    - by ptikobj
    I'm automatically generating a PDF-file with Platypus that has dynamic content. This means that it might happen that the length of the text content (which is directly at the bottom of the pdf-file) may vary. However, it might happen that a page break is done in cases where the content is too long. This is because i use a "static" spacer: s = Spacer(width=0, height=23.5*cm) as i always want to have only one page, I somehow need to dynamically set the height of the Spacer, so that it takes the "rest" of the space that is on the page as its height. Now, how do i get the "rest" of height that is left on my page?

  • Calculating ComboBox DropDownWidth in C#

    - by Jim Fell
    In my application a ComboBox gets resized, so that it is smaller. How do I re-calculate the DropDownWidth property? I know how to set it, but I'd prefer to calculate the proper width because its contents changes. Preferabley, I was thinking of something along these lines: int iMaxLen = 0; foreach item in comboBoxList { iMaxLen = (item.Length > iMaxLen) ? item.Length : iMaxLen; } comboBoxList.DropDownWidth = iMaxLen; Thanks.

    I want to have a link in the popup.html file for my extension that loads another file (which will be included with the extension) how can I do this? or will I need to keep it in the same page? I tried using this code: <a href="/mail.html"> <img id="newmail_icon" src="" width="16" height="16" /> <span id="newmail">loading</span><br /> </a> But when I click the link nothing happens. I just found out that adding target="_blank" to the link will make it work and open in a new tab, but I can't get it to open in the popup. I have tried target="_self" but it didn't do anything.
