61f30830df Help: Echo default scanner from variable instead 
of hardcoded string.
 2021-10-20 12:02:50 +02:00

4595af7f64 If scan_pre exists in the local config dir, 
execute it just before running scanadf. This
allows for last moment changes to the variables.
(In my case, I need to strip --page-height [...]
from PGHEIGHT for scanadf to work.)

44a6b0002d Fix the order of parameters. (Otherwise --resolution is ignored if --source is set) 2021-10-20 11:59:02 +02:00

1035d998cc Use a configuration file (if it exists) to allow the user to set preferred defaults, including TMP_DIR. Also move the initalization of SOURCE above the inclusion of the configuration. 2021-10-20 11:57:12 +02:00

d716cdbe8c Fix the multi-output loop 
Resolves #33.

Fixes the arithmetic comparison in the while loop being
incorrect.

Also, handles the situation in which there are more output
files being specified than scans available, in addition
to the already handled reverse situation.

d7484becbc Quote the device argument. 
Without doing so if the device includes a semicolon the following happens:

    % ./scan -x 'brother4:bus7;dev1'
    Scanning...
    scanadf: open of device brother4:bus7 failed: Invalid argument
    ./scan: line 248: dev1: command not found
    Found no scans.

d33c8caa71 performance: pnmtops to temp file 
For some reason when piping the output of pnmtops directly to ps2pdf,
conversion is very slow (especially for color scans).

When writing to an intermediate temporary file, conversion is fast.

Before:

________________________________________________________
Executed in   19.20 secs   fish           external
  usr time    4.01 secs    0.32 millis    4.01 secs
  sys time   20.63 secs    5.30 millis   20.62 secs

After:

________________________________________________________
Executed in  368.06 millis    fish           external
   usr time  378.06 millis    0.00 millis  378.06 millis
   sys time  100.00 millis    2.79 millis   97.21 millis

An improvement of over 50 times!

This should resolve #19.
