Public bug reported:
I use Ubuntu 17.10 and simple-scan 3.26.3.
1) The choice for scanning mode is "Text" or "Photo".
2) The preferences dialog allows to specify different values for "Text
resolution" and "Photo Resolution".
For the non-guru user some kind of weak logical conclusion is that "Text" mode
is lower resolution because we need less, and "Photo" is higher because
obviously we want our holiday pictures to be top notch :)
I scanned a document written with different colors using "Text" mode, just to
discover that everything was black!
After some experimentations and some googling, it appears that I am not the
only one puzzled by this.
Many people are fighting to find the black & white VS color mode choice.
The truth seems to be: "Text" is black & white (or maybe greyscale I do not
know), and "Photo" is color.
What about colored text and black & white pictures?
There are two dimensions to take into account:
* black & white/greyscale/color
* low/high resolution
The two words "Text" and "Color" are not correct representatives of
this.
Maybe you could start to give a more precise meaning like:
* Black & white 150dpi (recommended for text)
* Color 300dpi (recommended for pictures)
And let the well informed user choose.
Thank you
