The current Amiga hardware supports 6 and 8 planes, so for +now you should only use this values. + +.TP +\fB-normal\fP +Turns off -hamif/-24if/-dcif, -hamforce/-24force/-dcforce and +-cmaponly.

The default compression method is +byterun1. Compression requires building the ILBM image in memory; +turning compression off allows stream-writing of the image, but the +resulting file will usually be 30% to 50% larger. Another alternative +is the -savemem option, this will keep memory requirements for +compression at a minimum, but is very slow. + +.TP +\fB-cmethod\fP \fBnone\fP|\fBbyterun1\fP +This option does the same thing as \fB-compress\fP. + +.TP +\fB-map\fP \fIppmfile\fP +Write a normal ILBM using the colors in <ppmfile> as the +colormap. The colormap file also determines the number of planes, a +\fB-maxplanes\fP or \fB-fixplanes\fP option is ignored. + +.TP +\fB-cmaponly\fP +Write a colormap file: only BMHD and CMAP chunks, no BODY chunk, +nPlanes = 0. + +.TP +\fB-savemem\fP +See the \fB-compress\fP option. + + + + +.UN limitations +.SH LIMITATIONS +.PP +HAM pictures will always get a grayscale colormap; a real color +selection algorithm might give better results. On the other hand, +this allows row-by-row operation on HAM images, and all HAM images of +the same depth (no. of planes) share a common colormap, which is +useful for building HAM animations. + + +.UN references +.SH REFERENCES + +Amiga ROM Kernel Reference Manual - Devices (3rd Ed.) +Addison Wesley, ISBN 0-201-56775-X + + +.UN seealso +.SH SEE ALSO +.BR "ppm" (5)\c +\&, +.BR "ilbmtoppm" (1)\c +\& + + +.UN history +.SH HISTORY +.PP +For about a year in 1993-1994, there was a \fB-savemem\fP option. + + +.UN authoris +.SH AUTHORS +.PP +Copyright (C) 1989 by Jef Poskanzer. +.PP +Modified October 1993 by Ingo Wilken (\fIIngo.Wilken@informatik.uni-oldenburg.de\fP) +.SH DOCUMENT SOURCE +This manual page was generated by the Netpbm tool 'makeman' from HTML +source.
