compression in SaveBitmapToTIFFile

[Wolfgang]

Hello,

I am wondering if there are more details available concerning the compression algorithm available for this function. The help says:

TIF_COMPRESSION_RLE		1
TIF_COMPRESSION_JPEG		2
TIF_COMPRESSION_ZIP		3

However, the correspondence to the TIFF compression tag, see here, remains unclear to me, and help is welcome.

Thanks!

May be I should elaborate a bit more on my question:

I have used a hex editor trying to find out the compression tag used for the different methods available in CVI but failed. This may well be my fault. What I want to know are the values of the TIFF compression tag for the three compression algorithms in CVI...

Thanks.

These are the correspondences:

TIF_COMPRESSION_RLE = PackBits (32773)

TIF_COMPRESSION_JPEG = JPEG (7)

TIF_COMPRESSION_ZIP = Deflate (32946)

These correspondences should have been included in the documentation. Sorry about that.
