General Settings

General settings include all properties that have something to do in a broader sense with the appearances of program Image Viewer. This means beside others the used font style and size as well as the foreground and background color. Furthermore, on this page users can define which kind of file types are evaluated at all. But before discussing each setting value in more detail please get a first impression and take a closer look at figure below.

Panel of general program settings.

As shown in figure above the general settings panel is split into the groups Style and Filtering. Furthermore, there are two checkboxes and a button which are not assigned to a special group. But more about these controls later on.

Style

This group provides all in all three different buttons which can be used to change the program’s look & feel. See overview below for all the details.

Foreground

This button allows users to change the program’s foreground color respectively the color of shown text items. But be aware this text color setting only applies to the labels of the navigator. Clicking this button opens the standard color dialog box of Windows. The foreground’s default value is black.

Background

This button allows users to change the program’s background color. The chosen background color affects the program’s navigator as well as its picture display. Clicking this button opens the standard color dialog box of Windows. The background’s default value is white.

Font

This button allows users to define the font to be used. Changing this font affects the navigator as well as the picture display. Clicking this button opens the standard font dialog box of Windows. The font’s default value is Microsoft Sans Serif; 8.25pt.

Filtering

This group provides the possibility to define the set of file types that are processed by the navigator at all. Users can setup their own subset simply by marking or unmarking the individual checkboxes. The default subset of processed file types is PNG, BMP, JPEG, GIF and ICON.

Additionally, please note that all of the supported file types are by intention not assigned to program Image Viewer. This means in detail it is not possible to open those file types with program Image Viewer by double–clicking them in the Windows Explorer! This decision was made because otherwise an installation of the program would be required. Further, a bypassing of all assigned default applications is prevented as long as the file type registration is kept.

Right here it seems to be useful to have a short digression about every single file type.

PNG Portable Network Graphics is a modern and today common file format that for example supports transparency. Usually the extension *.png is used for files of this type.
BMP Bitmap is the historical file format of all Windows platforms. Usually the extension *.bmp is used for files of this type.
JPEG Joint Photo­graphic Experts Group is one of the file formats that are defined in the MPEG standard and is typically used in the field of digital photography. Usually the extensions *.jpg, *.jpeg, *.jpe, *.jif, *.jfif, and *jfi are used for files of this type.
GIF Graphics Inter­change Format is a file format with good compression but with low color depth. Additionally, files of this type can include animations which for example are interpreted by Web browsers. However, program Image Viewer does not support an animated displaying of files of this type. Usually the extension *.gif is used for files of this type.
ICON This is a file format that is typically used for so–called icon files. This file type is for example used on Window platforms to show programs and other files on the Desktop or inside the Explorer. But note program Image Viewer might be unable to show the picture inside an icon file as long as a respective file includes more than one icon. Usually the extension *.ico is used for files of this type.
TIFF Tagged Image File Format is similar to bitmap a format for raster graphics and is often used for scanned images. Usually the extensions *.tiff and *.tif are used for files of this type.
META Windows Metafile or Windows En­hanced Meta­file is a vector–based file format, which originally has been developed by Micro­soft®, to allow an image exchange between different programs. Furthermore, this file format is an integral part of the Windows clipboard. Usually the extensions *.wmf and *.emf are used for files of this type.

Theoretically, it would be possible to extend the program’s configuration file by additional file formats, but practically this is strongly discouraged. Because otherwise it could lead in unwanted side effects as well as an unpredictable program behavior!

Other Settings

Using checkbox Automatic image adjustment allows users to define whether a shown picture is automatically displayed in its default resolution or it is fit into the visible area. If this checkbox is marked then all pictures are fit into the visible area. If instead this checkbox is not marked then all pictures are shown in their default size. More information about this topic can be found in section Default Size. This checkbox is marked by default.

Using checkbox Automatic image rotation allows users to define whether it is tried to automatically rotate a shown picture. This is especially useful for photos that were taken vertically. Most of modern cameras are able to provide this information within a picture’s header. If this checkbox is marked then it is tried (for all pictures) to find and evaluate this information and to rotate pictures accordingly, if possible. If instead this checkbox is not marked then it is not tried to find this special information. In this case each picture is shown as it is. This checkbox is marked by default.

Button [Register] enables users to register program Image Viewer in a way that it can be started from within the Windows Explorer. On the other hand, if the program is already registered this button is used to remove the registration from the Windows registry. Detailed information about this topic can be found in sections Registration and Deregistration. Program Image Viewer is by default not registered.
