Please read the help topic "AutoScroll property (ILEADRasterView)" in the Main COM Object Help file. Yasir Alani LEADTOOLS Technical Support support@leadtools.com    Report

07-06-2008, 10:45 Yasir Alani Joined on 02-05-2007 Posts 225 Re: How to move the image on a Lead Raster Image You are right. That property only exists in our .NET controls, not in our Raster COM objects. Sorry about this mistake. However, there is another way to do it in our LEAD Raster View control, which is using the destination rectangle. First, set the AutoScroll property to False, then specify the location you want using the SetDstRect method. For an explanation, see the help topic "Specifying Only the Destination Rectangles".

07-07-2008, 4:42 Sohailsoh Joined on 06-04-2008 Posts 29 Re: How to move the image on a Lead Raster Image Thank you. Please let me know what is the difference between .NET controls and COm Objects? Am i not using the .NET controls? is it better to use the .NET controls? SetDstRect-> please help me in giving me an example in the mean while i will also try to find it in the topic you specified? Waiting for your prompt reply Thank you again.        Report

07-07-2008, 9:14 Sohailsoh Joined on 06-04-2008 Posts 29 Re: How to move the image on a Lead Raster Image I checked the example you referenced but it is just changing the position of the Raster Viewre COntrol not the position of the image inside. I want to keep the control on the form as it as and just want to move the image inside it to left, right, top or bottom to be adjusted under the circles.

07-07-2008, 10:56 Yasir Alani Joined on 02-05-2007 Posts 225 Re: How to move the image on a Lead Raster Image Our Raster COM objects can be used with different programming environments, including Visual Studio .NET (any version) and others (VB6, Visual C++ 6, etc.) Our native .NET classes v14.5 can only be used with Visual Studio .NET 2003 and later. The design of objects is different between the 2 interfaces. This means a program written using the LEAD Raster COM objects will have to be re-written if you want to convert it to the .NET classes. If you own LEADTOOLS Raster Imaging Pro 14.5 alone, it does not contain the .NET classes. Higher-end toolkits, such as LEADTOOLS Document and LEADTOOLS Medical toolkits contain both COM and .NET objects. About SetDstRect, the simplest example is something like this: 'Assuming you have a LEADRasterView control named axLEADRasterView1 axLEADRasterView1.AutoScroll = False axLEADRasterView1.SetDstRect(100, 100, 300, 200) You can change the  4 values in your code to match the location and size you need exactly.

Now i have all the required DLLS for Dot Net . But please let me know how can i add these controls into the toolsbox like the other standard .net controls on this toolbox. Thank you .    Report

07-14-2008, 11:21 Yasir Alani Joined on 02-05-2007 Posts 225 Re: How to move the image on a Lead Raster Image Does this mean you will no longer use the Raster COM objects and instead use the native LEADTOOLS .NET classes? If yes, then you will have to start over and write your application from scratch. To answer your question, you can find details in the help topic "Loading an Image From a Buffer" in the .NET Class Library (Main) Help file. Please look at the first 5 steps.

I am able to rewrite the code to the point where we were discussing in this post for the last time. As you can see in this post that i have posted some images with ared rectangle on it. I have to adjust the image under this rectangle with its eyes under the circles. I can move the image now on RasterImageViewer1 control with the help of OffSet. but i am in need of of more help on this point 1) When i rotate the image, the image distorted(Please see image ImageRotation.jpg) I am using the following code to rotate the image (Angle value is 45 or -45)    Private Sub RotateTest(ByVal image As Leadtools.IRasterImage, ByVal Angle As Integer)         Dim command As Leadtools.ImageProcessing.RotateCommand = New                     Leadtools.ImageProcessing.RotateCommand         command.Angle = Angle         command.FillColor = New Leadtools.RasterColor(255, 255, 255)         command.Flags = Leadtools.ImageProcessing.RotateCommandFlags.None         command.Run(image)     End Sub    Report
