libXpm supports two optional features to handle compressed pixmap files.
|
|
|
|
--enable-open-zfile makes libXpm recognize file names ending in .Z and .gz
|
|
and open a pipe to the appropriate command to compress the file when writing
|
|
and uncompress the file when reading. This is enabled by default on platforms
|
|
other than MinGW and can be disabled by passing the --disable-open-zfile flag
|
|
to the configure script.
|
|
|
|
--enable-stat-zfile make libXpm search for a file name with .Z or .gz added
|
|
if it can't find the file it was asked to open. It relies on the
|
|
--enable-open-zfile feature to open the file, and is enabled by default
|
|
when --enable-open-zfile is enabled, and can be disabled by passing the
|
|
--disable-stat-zfile flag to the configure script.
|
|
|
|
All of these commands will be executed with whatever userid & privileges the
|
|
function is called with, relying on the caller to ensure the correct euid,
|
|
egid, etc. are set before calling.
|
|
|
|
To reduce risk, the paths to these commands are now set at configure time to
|
|
the first version found in the PATH used to run configure, and do not depend
|
|
on the PATH environment variable set at runtime.
|
|
|
|
To specify paths to be used for these commands instead of searching $PATH, pass
|
|
the XPM_PATH_COMPRESS, XPM_PATH_UNCOMPRESS, and XPM_PATH_GZIP
|
|
variables to the configure command.
