Re: Saving a Multi-Page Image

I am having problems performing the above. I am using a class that is used in "MainDemo" which does save a file but it only saves the current image in a viewer. The following is the code:

Private _saver As ImageFileSaver = New ImageFileSaver

Dim saveImage As Leadtools.IRasterImage = Me.rivImageCopy.Image

If saveImage.PageCount = 0 Then

   Exit Sub

End If

_saver.Save(Me, objCodecs, saveImage)

When I debug the page count is 2 but only 1 image is saved. The class from MainDemo does do something with pagemode

 

First is this the correct thing to do or what?

 

Thanks

Dan,
It might be better to create a small test project and use the LEADTOOLS methods in it than to try to understand the whole main demo before you become familiar with the toolkit.

The RasterImage class can contain multiple images (pages). If you want to save more than one, you can use the following overload of the RasterCodecs.Save method:
Sub Save( _
   ByVal image As IRasterImage, _
   ByVal fileName As String, _
   ByVal format As RasterImageFormat, _
   ByVal bitsPerPixel As Integer, _
   ByVal firstPage As Integer, _
   ByVal lastPage As Integer, _
   ByVal firstSavePageNumber As Integer, _
   ByVal pageMode As CodecsSavePageMode _
)
The last 4 parameters of this method determine which pages are saved exactly and where they are placed in the output file. The LEADTOOLS .NET help file contains explanation and a code sample.
