  • chrome renders js different depending on the extension of the file to render [testcase included]

    - by pakore
    I was trying to implement an image panner I found here Chrome renders the same document differently depending on the extension of the file requested. I have created a test case, where it works when the file it's not named as test.xhtml You can download the test case from here Does anybody know why or how to solve it? I want my files to be .xhtml In IE and FF it works fine. Code: test.html / test.xhtml (change the name to see that works with one but not with the other). <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"/> <style type="text/css"> /*Default CSS for pan containers*/ .pancontainer { position: relative; /*keep this intact*/ overflow: hidden; /*keep this intact*/ width: 300px; height: 300px; border: 1px solid black; } </style> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script type="text/javascript" src="http://www.dynamicdrive.com/dynamicindex4/imagepanner.js"></script> </head> <body> <div class="pancontainer" data-orient="center" data-canzoom="yes" style="width: 350px; height: 200px; float: left; position: relative; overflow-x: hidden; overflow-y: hidden; cursor: move; "><img src="./test_files/image.jpg" style="position: absolute; width: 700px; height: 525px; left: -175px; top: -163px; display: block;" /> </div> </body> </html>

  • How to resize the UIView when CGAffineTransformIdentity

    - by Gowtham
    I am doing an app which has a feature to rotate and re size a view. i have implemented this feature but i do face an issue. My problem The View wil be resized when dragging its four corners, after resizing it i can rotate the view in both directions. Once the rotation is done, if i try again to resize the view by dragging its corner, the view's size gone to unpredictable value and its moving all around the screen. I googled lot finally i got the following solution The frame property is undefined when transform != CGAffineTransformIdentity, as per the docs on UIView I saw one app which has implemented the feature exactly what i wish to implement. How can i resize the UIView after rotation of UIView My code for resize the view Touches Began - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{ UITouch *touch = [[event allTouches] anyObject]; NSLog(@"[touch view]:::%@",[touch view]); touchStart = [[touches anyObject] locationInView:testVw]; isResizingLR = (testVw.bounds.size.width - touchStart.x < kResizeThumbSize && testVw.bounds.size.height - touchStart.y < kResizeThumbSize); isResizingUL = (touchStart.x <kResizeThumbSize && touchStart.y <kResizeThumbSize); isResizingUR = (testVw.bounds.size.width-touchStart.x < kResizeThumbSize && touchStart.y<kResizeThumbSize); isResizingLL = (touchStart.x <kResizeThumbSize && testVw.bounds.size.height -touchStart.y <kResizeThumbSize); } Touches Moved - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event{ CGPoint touchPoint = [[touches anyObject] locationInView:testVw]; CGPoint previous=[[touches anyObject]previousLocationInView:testVw]; float deltaWidth = touchPoint.x-previous.x; float deltaHeight = touchPoint.y-previous.y; NSLog(@"CVTM:%@",NSStringFromCGRect(testVw.frame)); if (isResizingLR) { testVw.frame = CGRectMake(testVw.frame.origin.x, testVw.frame.origin.y,touchPoint.x + deltaWidth, touchPoint.y + deltaWidth); } if (isResizingUL) { testVw.frame = CGRectMake(testVw.frame.origin.x + deltaWidth, testVw.frame.origin.y + deltaHeight, testVw.frame.size.width - deltaWidth, testVw.frame.size.height - deltaHeight); } if (isResizingUR) { testVw.frame = CGRectMake(testVw.frame.origin.x ,testVw.frame.origin.y + deltaHeight, testVw.frame.size.width + deltaWidth, testVw.frame.size.height - deltaHeight); } if (isResizingLL) { testVw.frame = CGRectMake(testVw.frame.origin.x + deltaWidth ,testVw.frame.origin.y , testVw.frame.size.width - deltaWidth, testVw.frame.size.height + deltaHeight); } if (!isResizingUL && !isResizingLR && !isResizingUR && !isResizingLL) { testVw.center = CGPointMake(testVw.center.x + touchPoint.x - touchStart.x,testVw.center.y + touchPoint.y - touchStart.y); } }

  • Displaying xaml resources dynamically?

    - by Robert
    I used Mike Swanson's illustrator to xaml converter to convert some of my images to xaml. The convert creates a viewbox that contains the image. These viewboxes I made resource files in my program. The code below shows what I'm trying to do: I have a viewmodel that has an enum variable called PrimaryWinding of type Windings. The values PrimD and PrimY of the enum select the respective PrimD and PrimY xaml files in the resources. <UserControl.Resources> <DataTemplate x:Key="PrimTrafo" DataType="{x:Type l:Windings}"> <Frame Source="{Binding}" x:Name="PART_Image" NavigationUIVisibility="Hidden"> <Frame.LayoutTransform> <ScaleTransform ScaleX="0.5" ScaleY="0.5"/> </Frame.LayoutTransform> </Frame> <DataTemplate.Triggers> <DataTrigger Binding="{Binding}" Value="PrimD"> <Setter TargetName="PART_Image" Property="Source" Value="Resources\PrimD.xaml" /> </DataTrigger> <DataTrigger Binding="{Binding}" Value="PrimY"> <Setter TargetName="PART_Image" Property="Source" Value="Resources\PrimY.xaml" /> </DataTrigger> </DataTemplate.Triggers> </DataTemplate> </UserControl.Resources> <!--The contentcontrol that holds the datatemplate defined above--> <Grid > <Grid.ColumnDefinitions> <ColumnDefinition Width="2*"></ColumnDefinition> <ColumnDefinition Width="2*"></ColumnDefinition> <ColumnDefinition Width="1*"></ColumnDefinition> </Grid.ColumnDefinitions> <ContentControl Grid.Column="0" Content="{Binding PrimaryWinding}" ContentTemplate="{StaticResource PrimTrafo}"/> </Grid> This code works. Only I can't resize the drawings to the size of the grid cell. I added the ScaleTransform class to resize the image. Is a Frame the wrong class to hold the drawings? Should I use the ScaleTransform class to resize the drawing to the size of the cell? And how can I do that dynamically?

  • Error:A generic error occurred in GDI+

    - by sanfra1983
    Hi, I created a web project on the server, and when I upload an image shows me the error Error: A generic error occurred in GDI +. I have read many links on the net that talk about this issue, and although I made the changes, nothing went wrong. I was thinking if the case is not an issue of permissions to folders. In fact I have two folders one inside the other. This is the code to resize the image: public Bitmaps ResizeImage (Stream stream, int? width, int? height) ( System.Drawing.Bitmap bmpOut = null; const int defaultWidth = 800; const int defaultHeight = 600; int width = lnWidth == null? defaultWidth: (int) width; int height = lnHeight == null? defaultHeight: (int) height; try ( LoBMP bitmap = new Bitmap (stream); ImageFormat loFormat = loBMP.RawFormat; decimal lnRatio; lnNewWidth int = 0; lnNewHeight int = 0; if (loBMP.Width <& & lnWidth loBMP.Height <lnHeight) ( loBMP return; ) if (loBMP.Width> loBMP.Height) ( lnRatio = (decimal) lnWidth / loBMP.Width; lnNewWidth = lnWidth; decimal = lnTemp loBMP.Height lnRatio *; lnNewHeight = (int) lnTemp; ) else ( lnRatio = (decimal) lnHeight / loBMP.Height; lnNewHeight = lnHeight; decimal = lnTemp loBMP.Width lnRatio *; lnNewWidth = (int) lnTemp; ) bmpOut = new Bitmap (lnNewWidth, lnNewHeight); Graphics g = Graphics.FromImage (bmpOut); g.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic; g.FillRectangle (Brushes.White, 0, 0, lnNewWidth, lnNewHeight); g.DrawImage (loBMP, 0, 0, lnNewWidth, lnNewHeight); loBMP.Dispose (); ) catch ( return null; ) bmpOut return; ) and this is the code that I insert in the codebehind: string filepath = AppDomain.CurrentDomain.BaseDirectory + img_veterinario / "; string = filepathM AppDomain.CurrentDomain.BaseDirectory + img_veterinario / img_veterinarioM; Reseize Reseize R = new (); Bitmap = photosFileOriginal r.ResizeImage (fucasiclinici.PostedFile.InputStream, 400, 400); Bitmap = photosFileMiniatura r.ResizeImage (fucasiclinici.PostedFile.InputStream, 72, 72); String filename = Path.GetFileName (fucasiclinici.PostedFile.FileName); photosFileOriginal.Save (Path.Combine (filepath, filename)); photosFileMiniatura.Save (Path.Combine (filepathM, filename)); Can you help me? Thanks
