I've got a routine that adds an image to a PDF. The routine works just great most of the time but occasionally, a TIF file comes along that takes a very long time to process (say 20 seconds per page). Other TIF files add OK, multipage TIF files work, just some TIF files have trouble. Anybody have an idea on what could be in the TIF to cause the problem? The file size of the problem TIF is small - only 171 KB.

Code seems straight-forward:
this.o.SetMeasurementUnits(0) && Pixels
this.o.SetOrigin(1) && Top Left
this.o.CompressImages(1)
this.ImageID = this.o.AddImageFromFile(tFile, tPage)

Just a note - I've tried it with Compression 1 and Compression 0 - doesn't seem to make a difference.
