Regarding TIFF images...

Compression:
#DEFINE EncoderValueCompressionLZW 2
#DEFINE EncoderValueCompressionCCITT3 3
#DEFINE EncoderValueCompressionCCITT4 4
#DEFINE EncoderValueCompressionRle 5
#DEFINE EncoderValueCompressionNone 6

ColorDepth:
1
4
8
24
32

SaveFlag:
#DEFINE EncoderValueMultiFrame 18

I posted a list of GDI+ constants on my blog sometime ago, you might want to check it out...
