Hi,

I had send the email below to Epson, but there is no reaction.

Can anyone tell me a better place, where to post this bug?

Hi there,

I suspect, there is a small bug in iscan_2.30.4-2_amd64.deb.

The problem of the bug is mentioned here: https://sourceforge.net/p/gscan2pdf/bugs/389/#04ec/a0ea

And here: https://gitlab.com/utsushi/utsushi/-/issues/68#note_626389990

In my experience, |scanimage --help| dynamically adapts its output upon the given options before |--help|, i.e., the stated default values of options differ upon them. Please compare:

|$ scanimage --source='Automatic Document Feeder' --scan-area=A4 --help [.....] Options specific to device `epkowa:usb:002:003': [.....] Geometry: --scan-area Maximum|A4|A5 Landscape|A5 Portrait|B5|Legal|Letter|Executive|CD [A4] Select an area to scan based on well-known media sizes. -l 0..215.9mm [5.89999] Top-left x position of scan area. -t 0..355.6mm [0] Top-left y position of scan area. -x 0..210mm [210] Width of scan-area. -y 0..355.6mm [297] Height of scan-area. --quick-format Maximum|A4|A5 Landscape|A5 Portrait|B5|Legal|Letter|Executive|CD [A4] Select an area to scan based on well-known media sizes. (DEPRECATED) [.....]|

|$ scanimage --scan-area=A4 --source='Automatic Document Feeder' --help [.....] Options specific to device `epkowa:usb:002:003': [.....] Geometry: --scan-area Maximum|A4|A5 Landscape|A5 Portrait|B5|Legal|Letter|Executive|CD [A4] Select an area to scan based on well-known media sizes. -l 0..215.9mm [0] Top-left x position of scan area. -t 0..355.6mm [0] Top-left y position of scan area. -x 0..215.9mm [215.9] Width of scan-area. -y 0..355.6mm [355.6] Height of scan-area. --quick-format Maximum|A4|A5 Landscape|A5 Portrait|B5|Legal|Letter|Executive|CD [A4] Select an area to scan based on well-known media sizes. (DEPRECATED) [.....]|

The latter still lists |--scan-area| and |--quick-format| as |A4|, instead |Maximum|. In the opinion of the developer of gscan2pdf this is a bug. I too think, he is right, as if frontends rely on this help defaults, the user gets presented the wrong values in the GUI.

Thanks to review this problem,

-Ulf
