Image has wrong Image.PixelFormat on Windows 7, not on XP

Posted By:      Posted Date: October 07, 2010    Points: 0   Category :Windows Application

Loading an image using System.Drawing.Image.FromFile and then examining the pixelformat - on Windows XP x64 (or x86) the format is a valid value such as PixelFormat24bppRGB but on Windows 7 (x64 or x86) the value returned is 8207, which is not a member of the PixelFormat enumeration.

This problem occurs using .NET framework 3.5 and 4.0

The code used is:

using System;
using System.Drawing;

public class itype {

    public static void Main( string[] args ) {

        Image image = Image.FromFile( args[0] );

        Console.WriteLine( "pixelformat of " + args[0] +
                       " = " + image.PixelFormat );

An image which shows this problem can be downloaded from http://www.xmlpdf.com/images/test.jpg

how to insert image in to WPF windows?

Converting a System.Windows.Control.Image object to byte array.

Hi i need to convert a specific System.Windows.Control.Image object into an (int) array, because i'm trying to convert a silverlight application into a wpf project. private void createGi02GradBrush()<br/> {<br/> WriteableBitmap oWriteableBitmap = new WriteableBitmap(256, 256);<br/> Image oImage = new Image();<br/> oImage.Arrange(new Rect(0, 0, 256, 256));<br/> oImage.Measure(new Size(256, 256));<br/> oImage.Source = new WriteableBitmap(256, 256);<br/> Gi02GradShaderEffect oGi02GradShaderEffect = new Gi02GradShaderEffect();<br/> oGi02GradShaderEffect.pArray = oPImageBrush;<br/> oGi02GradShaderEffect.gi1GradArray = oGi1GradImageBrush;<br/> oImage.Effect = oGi02GradShaderEffect;<br/> oWriteableBitmap.Render(oImage, null);//here<br/> oWriteableBitmap.Invalidate(); <br/> this.oGi02GradImageBrush = new ImageBrush();<br/> this.oGi02GradImageBrush.ImageSource = oWriteableBitmap;<br/> } I've found some similar topics however Image object is not the same and most of its methods aren't available. Here I'm rendering a writablebitmap with a given Image object, but in wpf we need an array. oWriteableBitmap.Render(oImage, null); Any idea? Thanks. Joseph.

Converting windows form to bmp - image crops when the screen resolution is changed


I am converting windows form to a bitmap file using   DrawToBitmap method.  My code looks like this.

            Dim wid As Integer = 760 '  Me.Width
            Dim hgt As Integer = 780 ' Me.Height
            Dim bm As New Bitmap(wid, hgt)
            Me.DrawToBitmap(bm, New Rectangle(0, 0, wid, hgt))
            bm.Save(CurDir() & "\sample.bmp")

This code work fine on desktop/laptop with the screen resolution 1024 x 768  or above.   If I use app on a table pc – with the screen resolution is 800 x 480, the image gets cropped. 
Any suggestion or alternate mode.


.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"

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

ASP.Net Upload Image to MS Access Database

As you learnt from the previous articles to upload image to the SQL Database in ASP.Net 2.0 and stream that image into the memory to retrieve it from the database and display it on the web page. In this article you will learn how to upload images to the MS Access database in ASP.Net 2.0

First of all create an Access Database and place it in the App_Data folder of ASP.Net web site project. Then create a table "tblImg" with the following fields:

Get pixel format, raw format, property id list and property items image in VB.net - C#.net.

n this simple article you will learn that how we can get pixel format, raw format, property id list and property items image in VB and C#.net.

Get Pixel Format:

Image consists of pixels to get the format of the pixel we have a property named pixel format. This property returns an enumeration of pixel format. This enumeration tells the pixel format.

To demonstrate make a window application. Drag one button and a picture box on form.

Now write the following code on Button click event:

Can't display an image from the database



My database has a products table that has images stored in a varbinary(MAX) column.

I'm trying to display product information in a repeater and trying to display the images as well by using a GenericHandler class but I can't get the image to show up in my page.

Here is my Handler.ashx class:

        Const buffersize As Integer = 1024 * 16
        Dim buffer(buffersize) As Byte

        While count > 0
