Writing TIFF Files with .NET

[Jim Kring]

I have been playing around with the possibility of using .NET to read and write TIFF files. I've hit a little bit of a wall when trying to configure the encoding parameters such as compression and color depth. I followed the example code on the MSDN website here. However, I am getting errors when I try to run this code in LabVIEW. I've been able to isolate the error to the encoderParams argument of the Bitmap.Save() method. However, I believe that I am constructing this argument properly, per the example code. Has anyone else played around with this?

According to the C++ example on MSDN it would seem that the EncoderParameter.value should be an Int64. So I simply tried to select the EncoderParameter(Encoder encoder, Int64 value) method instead of the EncoderParameter(Encoder encoder, Int16 value) and everything seems to be alright. At least I do not get any error anymore. Of course the Convert to Int16 could go away or be explicitedly converted to Int64 but LabVIEW will do that implicitedly too.

Hi Rolf. Thanks for the help. That works fine for me, too
