If the input image doesn't contain a 41transparency channel, the \fIalpha-filename\fP file contains all zero 42(transparent) transparency values. If you don't specify \fB--alphaout\fP, 43\fBtgatoppm\fP does not generate an alpha file, and if the input 44image has a transparency channel, \fBtgatoppm\fP simply discards it. 45.sp 46If you specify \fB-\fP as the filename, \fBtgatoppm\fP writes the 47transparency output to Standard Output and discards the image. 48.sp 49See 50.BR "pamcomp" (1)\c 51\& for one way to use 52the transparency output file. 53 54.TP 55\fB--headerdump\fP 56Causes \fBtgatoppm\fP to dump information from the TGA header to 57Standard Error. 58 59 60 61.UN lbAF 62.SH SEE ALSO 63.BR "ppmtotga" (1)\c 64\&, 65.BR "pamcomp" (1)\c 66\&, 67.BR "ppm" (5)\c 68\& 69 70.UN lbAG 71.SH AUTHOR 72.PP 73Partially based on tga2rast, version 1.0, by Ian J.
