If the input image doesn't contain an transparency channel, the \fIalpha-filename\fP file contains all zero (transparent) transparency values. If you don't specify \fB--alphaout\fP, \fBtgatoppm\fP does not generate an alpha file, and if the input image has a transparency channel, \fBtgatoppm\fP simply discards it. .sp If you specify \fB-\fP as the filename, \fBtgatoppm\fP writes the transparency output to Standard Output and discards the image. .sp See .BR "pamcomp" (1)\c \& for one way to use the transparency output file. .TP \fB--headerdump\fP Causes \fBtgatoppm\fP to dump information from the TGA header to Standard Error. .UN lbAF .SH SEE ALSO .BR "ppmtotga" (1)\c \&, .BR "pamcomp" (1)\c \&, .BR "ppm" (5)\c \& .UN lbAG .SH AUTHOR .PP Partially based on tga2rast, version 1.0, by Ian J.
