output raw PPM.
The default is to output plain PPM.
The
-.B -g
+.B -k
option makes
.I tojpg
-output grayscale images,
+output grey-scale images,
and the
.B -s
option makes it output scratched JPEG images.
.I Totif
accepts many options.
Choosing Huffman, T4, or T6 compression
-forces the output to be a bilevel image.
+forces the image to GREY1.
.TP
-.B -b
-Output a bilevel (GREY1) image.
+.B -3
+Convert the image to a true color RGB image.
.TP
-.B -B
-Output a grayscale (GREY2) image.
+.B -b
+Convert the image to a GREY1 black and white image.
.TP
.B -g
-Output a grayscale (GREY4) image.
+Use T4 one-dimensional compression.
.TP
.B -G
-Output a grayscale (GREY8) image.
+Use T4 two-dimensional compression.
.TP
.B -h
Use Huffman compression.
.TP
-.B -H
-Use T4 one-dimensional compression.
+.B -k
+Convert the image to a GREY8 grey-scale image.
.TP
.B -l
Use LZW compression.
.TP
.B -L
Use LZW compression with horizontal differencing.
-Note that some TIFF decoders may not accept horizontal
-differencing applied to images with depths less than eight.
-.TP
-.B -m
-Output a color (CMAP8) image.
+Some TIFF decoders may not support horizontal
+differencing applied to images of depths less than eight.
.TP
.B -p
Use Packbits compression.
.TP
-.B -r
-Output a color (BGR24) image.
-.TP
.B -t
-Use T4 two-dimensional compression.
-.TP
-.B -T
Use T6 compression.
+.TP
+.B -v
+Convert the image to an RGBV color-mapped image.
+.TP
+.B -y
+Convert the image to a GREY2 grey-scale image.
+.I Totif
+will then convert it to GREY4 before encoding
+because TIFF does not support depths of two.
+.TP
+.B -Y
+Convert the image to a GREY4 grey-scale image.
.PP
If there is only one input picture,
.I togif
Writing an animated GIF using
.I togif
is a clumsy undertaking.
