Recently, I had to do a few scans with my old but trusty BenQ 640BU. Given that I could not use any GUI due to a [long-standing Feisty bug](https://bugs.launchpad.net/bugs/85488), I tried to settle for command line scanning with the scanimage command from [SANE](http://www.sane-project.org). The main problem is that scanimage only saves images in PNM or TIFF formats. I wanted to use JPEG or PNG, but apparently that looked impossible to do.

|

Instead, I found that scanimage sends its results to standard output, and also that ImageMagick can accept standard input as source file, it was easy to convert on the fly:
|
|
|
|
[code lang='c']
|
|
scanimage --format pnm | convert -format png - test.png
|
|
[/code]
|
|
|
|
"-" tells convert to use the standard input. Another great example of the power of the command line.
