The patch above does not work as expected. Some problems still remain. This level change is beyond the scope of packagers (me), as it would induce pretty serious usage forks between the Red Hat version, and the pristine sources, please contact the upstream maintainer with this request if you really need this functionality. |
Most of utilities from libtiff (such as fax2tiff and etc) can not output to stdout. This requires to use files when doing multiple format conversion. The patch below fixes this problem. It adds a name - (as in GNU utilities) which indicates stdin for reading or stdout for writing. After this adding an option -o - to fax2tiff causes fax2tiff (and the other utilities) to print to stdout as expected. Then the output can be converted to ps without using a file. --- tiff-v3.5.5/libtiff/tif_unix.c.orig Tue Jul 4 09:00:13 2000 +++ tiff-v3.5.5/libtiff/tif_unix.c Tue Jul 4 09:30:14 2000 @@ -149,6 +149,14 @@ if (m == -1) return ((TIFF*)0); + /* check for stdout. */ + if(strlen(name)==1 && *name=='-') { /* use stdin or stdout stream */ + if(mode[0]=='r') { + fd=0; /* stdin */ + } else { + fd=1; /* stdout */ + } + } else { /* open as a file. */ /* for cygwin */ #ifdef O_BINARY m |= O_BINARY; @@ -159,6 +167,7 @@ #else fd = open(name, m, 0666); #endif + } if (fd < 0) { TIFFError(module, "%s: Cannot open", name); return ((TIFF *)0);
