4. Questions and Answers

These are the questions that never have been asked and the answers I would have given if they were asked.

Question:
Why is this program called "QuiteInsane"? Isn't this a stupid name?
Answer:
About 99% of all programs have stupid names, one more doesn't matter. I was simply looking for a name, which begins with a "Q", like many other applications that use Qt, and which contains "SANE".
Question:
QuiteInsane compiles just fine, but linking breaks with the message:

g++: /usr/local/lib/.libs/libsane.so: No such file or directory

What does this mean?
Answer:
This is caused by a bug in the SANE versions < 1.0.4. Open the file "libsane.la" under /usr/local/lib (or where else you've installed SANE) with an editor. Change the line
installed=no
to
installed=yes
and run make again.
Question:
Configure breaks with an error message when it checks for Qt. What can I do?
Answer:
If you installed the Qt sourcepackage, you probably didn't set QTDIR correctly. Try the following:
export QTDIR=/YourPath/qt-2.2.x
(if your shell is bash, ksh, zsh or sh)
setenv /YourPath/qt-2.2.x
(in case your shell is csh or tcsh).

You have to replace "YourPath" with the real path, and qt-2.2.x with the real Qt version, of course. If you've installed a RPM package, make sure, that the devel package is also installed; many distributions split Qt in two packages.
Question:
When I start QuiteInsane, a message box is shown which is telling me, that no devices were found. What might be wrong?
Answer:
This probably isn't a problem related to QuiteInsane. Try to run "scanimage -L" from the command line. Does this result in a list of devices? If it does, you should report this as a bug in QuiteInsane. Otherwise please read the SANE documentation for information about how you can set up your scanner correctly.
Question:
When I'm running QuiteInsane, the preview button is always disabled. Why?
Answer:
This button is (at least for the moment) only enabled if the backend allows to set the scan area options. Otherwise it is disabled (e.g. when you are using the pnm backend).
Question:
The print dialog shows two spin boxes, which allow to set the resolution. They are often set to values that are not supported by my printer.
Answer:
The values you can set here have absolutley nothing to do with the capabilities of your printer, they specify the image resolution. E.g. if you've scanned an image with a resolution of 300x200 dpi and set these values to 300 and 200, then the result is a printed image with the same size as the original image. If you plan to print the scanned image, you should choose a resolution close to your printers capabilities. It doesn't make much sense to scan with a resolution of 1200dpi, if your printer only supports 300 dpi.
Question:
I'm using a parallel port scanner which shares the port with a printer. When I'm using the "Multi scan" mode to scan and print multiple images, I get error messages like "Error during device IO".
Answer:
This is a problem with parallel port scanners and printers in general. QuiteInsane can not determine whether printing has been finished; it only knows, that the data has been send to the print queue. Therefore it's possible, that QuiteInsane attempts to start a new scan while the printer just started to print. Since both devices use the same port, this leads to an error message.
