The file size seems to get bigger and bigger on subsequent saves. My action are as follows:
'Load image
Set LoadedImage = codecs.Load_10(mvarImage, ImageInfo.BitsPerPixel, CodecsLoadByteOrder_BgrOrGray, 1, 1)
'do some processing like flip image, then save
codecs.Save_4 RasterImageViewer1.Image, mvarImage, ImageInfo.Format, ImageInfo.BitsPerPixel, 1, 1, 1, CodecsSavePageMode_Replace
The file size seems to increase by a single page size each time this operation is done. Any ideas?

The CodecsSavePageMode.Replace does not actually replace the specified page. The index will just point to the new page instead of the old page. Therefore, the file size will grow for each page "replaced" because the page being "replaced" is not deleted.
If you are dealing with TIF file format, you can use the RasterCodecs.CompactFile method.
For more information, please check our .NET help file.
If you are using other file formats, and you want to save a one page file, use the Overwrite flag.
If you want to save a multipage file, load all the files and save them to a new file.

Thanks. This feature seems to work for most of my TIFF files but sometimes I get the attached error. Any ideas?
BTW, the ActiveX object does not have the CompactFile method. How to do it there?

When exactly do you face this error? Can you specify which function/method produces this error?
Also, does this happen with all files or only specific ones? If this issue is specific to some files, please send me a small sample file in a ZIP or RAR file.
You can either post it here or send it to
support@leadtools.com and mention this post.
When attaching to the forums, do not use the "Preview" feature.
Regarding the CompactFile method, you need to define a raster codecs variable such as:
Dim codecs As RasterCodecs
And then use this variable for the CompactFile method such as:
codecs.CompactFile_2 "c:\test.tif", "c:\test2.tif", 0
