3.5 QuiteInsanes options window

If you click the "Options" button in the main window, the options window is shown. It allows you to set the following options:

Metric system


Use the radiobuttons to set your preferred metric system. Choose between "Millimetre" (mm), "Centimetre" (cm) and "Inch" (inch). This setting affects all SANE options displayed in the main window which have an attached unit of SANE_UNIT_MM (see the "SANE Standard" for further information), the preview window and also the print dialog.

Layout


Use the radiobuttons to change the layout. Layout means the way how the options supported by your scanner are displayed in the main window. Four layouts are available:
  1. Scrollview
    All option widgets are placed in a scrollview. This normally isn't regarded as good GUI design. But please keep in mind, that the main window is created at runtime and has to support a lot of different backends. At least, the scrollview ensures, that QuiteInsane is usable on 800x600 pixel displays without having a main window with a height bigger than you desktop height.
  2. Tabwidget
    Every option group is placed in a separate tab of a tabwidget. Using this layout may result in a main window height bigger than the desktop height, e.g. if the backend places many options in a single group.
  3. Multi window
    All options of the first option group a displayed in the main window. For every additional group a button is added to the main window. Clicking on such a button displays the options of this option group in a separate window.
  4. List
    This layout works similar to the Tabwidget layout, but needs less space for backends that pu their options in many different groups.
If you activate the Use separate preview window checkbox, the preview window is displayed as a separate toplevel window; otherwise the preview window becomes a part of the main window.
Normally, QuiteInsane has built-in context help buttons ("What's this" buttons). On some window-managers however, the windows titlebar contains such a button already. In this case, you can disable the built-in buttons by de-selecting the Enable context help buttons checkbox.

Style



With this combobox, you can change QuiteInsanes "look and feel". Please have a look at the Qt documentation for further information on styles. The following descriptions are almost quotes from the Qt documentation.
  1. Windows
    This is the default style. Looks like ... Windows.
  2. Motif
    It almost completely resembles the original Motif look as defined by the Open Group, but also contains minor improvements.
  3. Motif plus
    Motif-ish look and feel with more sophisticated bevelling as used by the GIMP Toolkit (GTK+) for Unix/X11.
  4. Platinum
    This style tries to resemble a Macinosh-like GUI style.
  5. SGI
    SGI look and feel.
  6. CDE
    This style provides a slightly improved Motif look similar to some versions of the Common Desktop Environment (CDE). The main difference are thinner frames and more modern radio buttons and check boxes.

Auto-selection



This page supplies various settings to adjust the automatic preview-selection feature.
  1. Standard deviation factor (color)
    To determine, whether a line/row of the image belongs to the background, QuiteInsane calculates the standard deviation for every line/row. The factor is used to calculate the maximal standard deviation a line/row may have to be considered part of the background. You should increase this value, if the detected part of the preview is smaller than the image, and decrease it, if the detected part of the preview is greater. This value is used for color scans.
  2. Standard deviation factor (gray)
    See "Standard deviation factor (color)". This value is used for grayscale scans.
  3. Minimal size
    Set the minimal size for the preview image(s). The smallest size an image may have is one percent of the maximal scansize.
  4. Background gray value is
  5. Enable automatic preview selection
    If you select this checkbox, the automatic preview selection is started automatically after a preview scan.
Hint: The automatic preview selection also works in multi-selection mode. In this case, the images must be ordered from top to bottom with some space in between and one image in a row.

Scanner



OCR command



QuiteInsane uses gocr for optical character recognition. It is run using the QProcess class. This means, that QuiteInsane doesn't link against the gocr library and that there's no need to recompile QuiteInsane when you install gocr after you've installed QuiteInsane. It's often sufficient to simply fill in "gocr" here, but it's also possible to use additional options, just like it had been started from the command line. Please have a look at the gocr documentation for further information. You can also run gocr from the command line like gocr --help. This will display a short description of the available options.

Image compression/quality



You can adjust the compression/quality for those image formats, that support it (at the moment PNG, TIFF, JPEG).

History



  1. Enable history
    Select this checkbox to enable the history. Whenever you save an image, an entry is added to the history file.
  2. Maximum number of entries
    If you select this checkbox, you can limit the number of entries in the history file. Use the spinbox on the right side to set the maximum value.
  3. Create preview
    If you select this checkbox, a preview image is created automatically when an entry is added to the history file.
  4. Delete on exit
    If you select this checkbox, the history file is deleted when you quit QuiteInsane.

Viewer



  1. Number of undo steps
    Set the number of undo steps. At least for the moment, QuiteInsane simply makes a copy of the complete image for every undo step. This can result in a huge memory usage.

Preview



  1. Use smooth scaling
    If you enable this option, QuiteInsane will use a smooth scaling algorithm for the preview image, which normally looks better, but is also a bit slower.
  2. Enable continous update
    If you enable this option, QuiteInsane will continously update the preview image during a preview scan.
  3. Limit preview resolution
    QuiteInsane normally calculates the preview resolution depending on the size of the preview window and the zoom-level. This can result in preview-scans with a rather high resolution. If you don't like this, then you can set a limit for the preview resolution here. Please note, that it is possible that QuiteInsane uses a higher resolution despite of your settings. This can happen, if the backend specifies a list of fixed preview resolutions. E.g. a backend could allow the resolutions 50, 100, 200, 300 ,400 and 600 dpi. If the limit for the preview resolution is set to 300 dpi and the calculated preview resolution is e.g. 305 dpi, then QuiteInsane might ignore your limit and choose a resolution of 400 dpi instead.

Filename generation



  1. Filecounter increment
    When a new filename is created, the counter is increased by the value specified here.
  2. Prepend zeros
    Zeros are prepended to the counter, when the counter has less digits than specified here.

Miscellaneous



  1. Documentation path
    Normaly not needed, but maybe useful if the documentation is not installed under the standard path.
  2. Enable optional warnings
    Some of the warnings can be disabled by selecting the Don't show this message again checkbox. If you want to enable them again, activate this checkbox.
  3. Size warning (in MB)
    When selected, the image-information in the mainwindow is displayed with a red background, when the scan-size exceeds the specified limit. That's just a warning, that you are going to scan a huge image.
