size of dropped image

  
hi!! i have a drag and drop handle on a canvas which displays a image on canvas when dropped a file on it: private void DropHandle(object sender, System.Windows.DragEventArgs e) { string[] arrstrFileNames = e.Data.GetData(DataFormats.FileDrop, true) as string[]; if (first) { MenuItem mnu1 = new MenuItem(); mnu1.Header = "Rotate"; mnu1.Click += new RoutedEventHandler(Rotate_Click); MenuItem mnu2 = new MenuItem(); mnu2.Click += new RoutedEventHandler(Crop_Click); mnu2.Header = "Crop"; MenuItem mnu3 = new MenuItem(); mnu3.Header = "Delete"; mnu3.Click += new RoutedEventHandler(Delete_Click); mnu.Items.Add(mnu1); mnu.Items.Add(mnu2); mnu.Items.Add(mnu3); } if (arrstrFileNames == null || arrstrFileNames.Length < 1) return; try { BitmapImage bmp = new BitmapImage(); bmp.BeginInit(); bmp.UriSource = new Uri("file:///" + arrstrFileNames[0].Replace("\\", "/")); bmp.EndInit(); Image img = new Image(); img.Source = bmp; img.Width = 300; img.Height = 300; RotateTransform rt = new RotateTransform(); img.LayoutTransform = rt; if(first==true) img.ContextMenu = mnu; first = false; assig

setting inline image size with css?

  
I have an inline image in the header of a page that's height is being set with CSS.  The actual height of the image is slightly taller than what it's currently set to with css.  I like doing this this way because it was easier to get the image to the right size.  It avoided multiple attempts in photoshop.Is it a bad idea to set the height of an image this way?   I'm only concerned with the major modern browsers.  Are there any side effects of this that I should be aware of?

BitmapImage detect image size before calling EndInit()

  
Hi, I'm using the following converter to create the thumbnails images: public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { try { BitmapImage bi = new BitmapImage(); string FilePath = value as string; if (null != FilePath) { bi.BeginInit(); bi.DecodePixelHeight = 80; bi.CacheOption = BitmapCacheOption.OnLoad; bi.CreateOptions = BitmapCreateOptions.DelayCreation; bi.UriSource = new Uri(FilePath); bi.EndInit(); } if (bi.CanFreeze) { bi.Freeze(); } return bi; } catch { return DependencyProperty.UnsetValue; } }   The problem is that I want to detect the image file height before generating the actual BitmapImage. In other words I need something like this:   bi.BeginInit(); if(bi.Height > 80) { bi.DecodePixelHeight = 80; } bi.CacheOption = BitmapCacheOption.OnLoad; bi.CreateOptions = BitmapCreateOptions.DelayCreation; bi.UriSource = new Uri(FilePath); bi.EndInit();   Which of cause can't be done before the EndInit() has been called. Is there is any other solution that doesn’t require creating some sort of Image class and loading the image file into it. The problem is that I'm expecting to hav

create polyline size relative to image clicked

  

hi!!

i am creating a path geometry using polyline:

 

 System.Windows.Point Point1 = new System.Windows.Point(50, 10);
      System.Windows.Point Point2 = new System.Windows.Point(200, 10);
      System.Windows.Point Point3 = new System.Windows.Point(200, 100);
      System.Windows.Point Point4 = new System.Windows.Point(10, 100);
      System.Windows.Point Point5 = new System.Windows.Point(10, 50);
      System.Windows.Point Point6 = new System.Windows.Point(50, 10);
      PointCollection polygonPoints = new PointCollection();
      polygonPoints.Add(Point1);
      polygonPoints.Add(Point2);
      polygonPoints.Add(Point3);
      polygonPoints.Add(Point4);
      polygonPoints.Add(Point5);
      polygonPoints.Add(Point6);
      yellowPolyline.Points = polygonPoints;

this is a rectangle which is clipped from top-left,

actually i want to create dynamically a polyline whose size is relative to the image i click on the canvas 

and then apply than clip that image using that polyline,,so that the image looks clipped from top-left

Controlling Page Image Size / Scale

  
I have created a custom master page for a WSS 3.0 site and all is working well except for the fact that I want to use the default page images that are provided, but they are too wide for the area available.  I have tried setting the table width but the width of the image seems to override that, so I would like to know if there is a way I can control the size (or better yet the scale) of the page image when it is displayed in order to have it fit within the area I have on the custom master page.

Thanks in advance,

Resize image and get new byte size without saving it

  

Hi Guys,

I'm making an application that needs to be able to take a user specified image file and upload it into a database that only accepts images of 10 KB or less. So I want to let the user select an image and then have the option of resizing it and if possible also decreasing the quality - I'm sure I can figure out how to do both of these things on my own but the thing I'm not sure about is how I can tell what size the resulting image will be without actually writing it to disk. I thought the SourceStream property of the BitmapSource class would be useful but when I try to access it I just get told that the stream has been closed. Any ideas?

 

Thanks

Chris

.NET converts pixels to points and creates a wrong image size

  

I have an image of size 144 pixels (I measured the image size using both irfanView and Photoshop).

However, when opened in a window using the following xaml, the image's width, measured both by the ActualWidth parameter and by the same graphic software, is 192 pixels.

It turns out that 141 points = 192 pixels (as 1pt=1.33px).

So it seems like .Net opens the image, measure it size in pixels and draws the image with the same size but in points.

Here is the XAML and code:

  <Window x:Class="test_image_resizing.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    

GridView Sorting/Paging : 'REAL' AJAX with Asp.Net Series

  
This is a continuation of my 'REAL' AJAX with Asp.Net (not Asp.Net AJAX) series posts for those of us trying to stop relying on Asp.Net 'AJAX'.

Ok, nothing too dramatic to start things off, we are going to make some tabled data sortable and pagable all without using a bit of postback. Not only that, but it is going to be incredibly easy!

Reduce ASP.NET Page size and complexity using JQuery

  
This is my first post on asp.net blog. ASP.NET Ajax and JQuery are two different ajax framework. In this post I will show, how we can enhance gridview using ASP.NET Ajax and JQuery. I also compare the implementation of these frameworks. In next posts i will explain more about JQuery and ASP.NET Ajax and also tell you "How to combine the power of both framework". My Future post will related to ASP.NET and related frameworks.

Built-in Functions - Text and Image Functions in SQL Server

  
Text and image functions operate on TEXT, NTEXT and IMAGE data types. These data types are deprecated with SQL Server 2005 and should be replaced by VARCHAR(MAX), NVARCHAR(MAX) and VARBINARY(MAX) when possible. Alternatively you can also consider storing large string values using XML data type. Text and image functions are nondeterministic.

Future versions of SQL Server will not support TEXT, NTEXT and IMAGE data types. Columns with TEXT / NTEXT data type do not support commonly used string functions such as LEN, LEFT, RIGHT, etc. Furthermore, due to the large size of TEXT data you''re likely to see performance issues if you store such data in the database. However, at times you can''t help but use the TEXT / NTEXT / IMAGE data types (for example when supporting 3rd party databases when you cannot change the schema) - this is when text and image functions come in handy.

Program for Format Conversion of An Image

  
.NET provides extensive support for image conversion. Any image can be processed from one format to another. Most common formats to which .NET have support for are .BMP, .EMF, .GIF, .ICO, .JPG, .PNG, .TIF and .WMF.

Configuring Profile Image Export in SharePoint 2010

  
It's no secret that I am thrilled with the new social features of SharePoint 2010. I am most excited about the new Profile Picture handling. I strongly believe that the more we can show the faces of our colleagues to one another the more connected we will feel. Clearly Microsoft feels that way as witnessed by the many features that make use of the Profile Image like the Activity Feed and Colleagues list
