Package: pngcrush
Version: 1.6.2-1
Followup-For: Bug #337186
Changelog says:
* Fixed typos in debian/pngcrush.sgml.
Closes: #337186.
...but:
% man pngcrush | grep -n 'extention\|preceeding'
101: -e ext Specify a new extention ext for all output files.
242: on the filtered IDAT chunk for the method of the
preceeding
Attached is a new patch, which also corrects the inconsistent usage of 'grey'
and 'gray'.
Hope this helps...

.IP "\fB-c type\fP" 10
Set the output image color type to \fItype\fR, one of [0, 2, 4, or 6] (see
section \fI"Color Types"\fR ). Future versions of \fBpngcrush\fR will also
allow color type 3, if there are 256 or fewer colors present in the input file.
Color types 4 and 6 are padded with an opaque alpha channel if the input file
does not have alpha information. You can use 0 or 4 to convert color to
grayscale. Use 0 or 2 to delete an unwanted alpha channel. Default is to use
same color type as the input file.

-Color counting. This option allows \fBpngcrush\fR to perform further

an opaque image and/or will reduce a true color image that is completely grey
to greyscale representation. (This option is currently disabled.)

The PNG specification provides for five color types. The color type
determines how the IDAT chunk will be interpreted by the decoder. Choosing a
color type appropriate for the color information in an image can reduce the
size (See the \fB-cc\fP option). Following are the PNG color types followed by
their supported bit depths (Note \fBpngcrush\fR does not support changing a
file to color type 3 from another color type.):
