Hi

i'm using the following code to rotate the image ..

Leadtools.ImageProcessing.RotateCommand _command = new Leadtools.ImageProcessing.RotateCommand();

_command.Angle = iAngle;

_command.FillColor = new Leadtools.RasterColor(System.Drawing.Color.White);

_command.Flags = Leadtools.ImageProcessing.RotateCommandFlags.Resize;

_command.Run(_viewer.Image);

Kalyan,
You have to run the rotate command on each page separately. To do that, loop from 1 to _viewer.Image.PageCount, update the _viewer.Image.Page with the loop index value, and re-run the command inside the loop.

The help topic IRasterImage.PageCount Property contains a sample that uses one of the processing commands on all pages.

Kalyan,
If you use the RasterCodecs.Save method with a RasterImage object after running any processing command, all images are saved in their current state after the processing you did.

This means if you rotated one or more pages, they will be saved in their new rotation position.

Hi,

 

i was successfully able to rotate and save the multipage tiff image ..but for every single rotation command the size of the documnet is doubling ...

How to restrict the size to be to the original ?

Here is my code for rotating and saving of a multi page tiff document

Leadtools.ImageProcessing.RotateCommand _command = new Leadtools.ImageProcessing.RotateCommand();

_command.Angle = iAngle;

_command.FillColor = new Leadtools.RasterColor(System.Drawing.Color.White);

_command.Flags = Leadtools.ImageProcessing.RotateCommandFlags.Resize;

_command.Run(_viewer.Image);

RasterCodecs rasterCodecs = new RasterCodecs();

Leadtools.Codecs.CodecsImageInfo imageinfor = rasterCodecs.GetInformation("tmp.tif" ,true);

MessageBox.Show( imageinfor.Compression.ToString());

IRasterImage rasterTemp = _codecs.Load("tmp.tif");

_codecs.Save(_viewer.Image,"tmp.tif",RasterImageFormat.TifCcittGroup4,imageinfor.BitsPerPixel,rasterTemp.Page,rasterTemp.Page,1,CodecsSavePageMode.Replace);

 

after the End of the save the image Size is Getting double..

Kalyan,
The following post gives an explanation why this happens, but the solution in case is slightly different:
http://support.leadtools.com/SupportPortal/cs/forums/5000/ShowPost.aspx#5000

In your case, you are loading all images and saving them back again. Using the Replace flag causes all modified images to be added to the file, which doubles its size.

The solution is to save all modified images into a NEW temporary TIFF file using the Append flag, then delete the original file when finished and rename the temp file to the original name.
