I have a .tifabc file (C:\test.tifabc) and I want to get that file and convert it to a .tif without having to open the image into a rasterimageviewer screen.

I know that


<span style="color=blue;">
<font face="Lucida Console" size="2">
codecs.Save(_ipr._viewer.Image, strm, RasterImageFormat.Tif, 1, 1, _ipr._viewer.Image.PageCount, 1, CodecsSavePageMode.Overwrite);
</font>
</span>


will save the image from the viewer to a memorystream, but I would like to know how to do it without even pulling it up in the viewer. I just need to grab the file, save as tif in a memorystream.

Any assistance would be appreciated.
Thanks.

What is the format of your .tifabc file? Is it a TIFF file with LEAD ABC compression?
Also, what is the format you wish to convert it to? I know it's TIFF, but you didn't specify a TIFF sub-type.
Your code appears to be saving as 1-bit uncompressed TIFF. Is this the format you need?

If you want to convert any supported format to uncompressed TIFF, you can use RasterCodecs.Load and RasterCodecs.Save without the need to display anything.
Instead of using RasterImageViewer.Image to hold the bitmap that gets loaded and saved, you could simply declare a temporary object of type RasterImage like this:
Leadtools.RasterImage temp_image = codecs.Load(@"C:\test.tifabc");
codecs.Save(temp_image, strm, ...);

Ok. I am closer than before. I get the tif. But when you try to view it, it is just blank.

Here is some of the code. Not sure if I got it all right.


public RasterImage LoadImageGIRTemp(int GIRIMGDocumentHeaderID)
{
GIRIMGDocumentHeader gdh = new GIRIMGDocumentHeader();
gdh.LoadByPrimaryKey(GIRIMGDocumentHeaderID);
RasterCodecs io = new RasterCodecs();
RasterSupport.Unlock(Leadtools.RasterSupportType.Abc, "?????");
RasterSupport.Unlock(Leadtools.RasterSupportType.Document, "??????");
RasterImage temp_image = io.Load(@"C:\test.tifabc")
return temp_image;
}

RasterImage temp_image = LoadImageGIRTemp(Convert.ToInt32(dr[GIRIMGDocumentHeaderSchema.ID.FieldName].ToString()));

MemoryStream strm = new MemoryStream();
RasterCodecs codecs = new RasterCodecs();
codecs.Save(temp_image, strm, RasterImageFormat.Tif, 1, 1, temp_image.PageCount, 1, CodecsSavePageMode.Overwrite);

I found the problem. It is working, but after the codecs.save(), I had to set the strm back to the beginning with strm.Position = 0; so the stream then could be used in my email code.

Thanks.
