Microscopy Image Browser Preferences
This dialog provides access to preferences of Microscopy Image Browser. Allows to modify colors of the Selection, Model and Mask layers, default behaviour of the mouse wheel and keys, settings of Undo...
Please note, im_browser stores its configuration parameters in a file that is automatically generated after closing of im_browser:
- for Windows - c:\temp\im_browser.mat or when c:\temp is unavailable in the Windows TEMP directory (C:\Users\User-name\AppData\Local\Temp\). The TEMP directory can be found and accessed with Windows->Start button->%TEMP% command
- for Linux - in a directory where im_browser is installed, or in the local tmp directory (/tmp)

Preferences
- Mouse Wheel. Allows to choose between two possible actions done with the mouse wheel. When Zoom is selected, rotation of the mouse wheel will result in zoom in/out action; when scroll is selected rotation of the mouse wheel will result in change of the shown slices. Note! the mouse wheel may be used together with Shift button to scroll more than one slice at the time, see more in Image View Panel/Extra parameters for the slider
- Left Mouse Button. Allows to select action for press of the left mouse button. When pan is selected the press and hold of the left mouse button will result in moving of the shown image to left-right and up/down directions. When select is selected the left mouse button can be used for making selections. Note! The left and right mouse buttons are mirrored, i.e. if one action (pan or select) is selected for the left mouse button, the right mouse button implements the second available action.
- Image Resize Method. Modifies a way how image is resized during on screen zoom in/zoom out action. Use 'nearest' to see unmodified pixels and 'bicubic' for smooth appearance. Note! the nearest option gives the fastest and bicubic the slowest performance. It is also possible to toggle the this from a dedicated button in the MIB toolbar.
- Disable Selection. When Selection is disabled it is not possible to use the Selection layer for segmentation. In this situation memory requirements are lower.
Undo Settings
Modification of Undo parameters.
A brief demonstration is available in the following video:
https://youtu.be/PrY3Eo02gU8
- Enable - enable/disable undo. When the memory is limited it may be recommended to set the Enable undo setting to the no state.
- History Steps - maximal number of history steps to keep in memory. Note! requires restart of Microscopy Image Browser to apply this modification.
- 3D History - number of 3D datasets that can be stored. When memory is limited it is recommended to set this value to 0. Note! requires restart of Microscopy Image Browser to apply this modification.
Interpolation Settings
Defines type and parameters of the interpolation for the Selection layer to use (i - shortcut, or Menu->Selection->Interpolate).
A brief demonstration is available in the following videos:
Shape interpolation: https://youtu.be/ZcJQb59YzUA?t=4m3s
Line interpolation: https://youtu.be/ZcJQb59YzUA?t=2m22s
- Type - two types are available: shape or line. The line method is the best for interpolation of a non-closed lines between the slices.
- Number of points - number of points to use for the interpolation, more points give smoother results, white the less points is faster.
- Line width - defines width of the line after the interpolation.
Models panel
The models can be encoded in two ways:
- 63 materials, default, allows to store Models, Selection and Mask layers in a single memory container. Reduce memory requirements but limits the number of materials to 63.
- 255 materials, allows to have up to 255 materials in the model, but requires additional computer memory to keep Selection and Mask layers, which means that for uint8 class of the datasets memory requirements are doubled.
Annotations panel
Models may include annotations. The annotations are strings of text bound to certain coordinates within the dataset. Annotations may be accessed from the menu entry: Menu->Models->Annotations.
- The Color button, allows to select a color for annotations.
- The Font size combo box allows to tweak the font size for the annotations.
A brief demonstration is available in the following video:

The Shortcuts button
Shortcuts for keys may be customized using the Define shortcuts for keys dialog that is started with this the Shortcuts button. The list of default shortcuts is available from the Key & mouse shortcuts page.
A brief demonstration is available in the following video:

Colors
Modification of default colors of the Selection, Mask, Model layers and defining color look-up table (LUT). The upper table shows the list of predefined colors for Materials of the Model layer. The lower table shows LUT for colors of the color channels to use with the LUT mode (View Settings Panel->LUT checkbox)
A brief demonstration is available in the following video:
https://youtu.be/A5HHVd5bfJ0
- Modification of the Model and LUT colors. The rows in tables represent color in Red:Green:Blue format in range from 0 to 255. The colors may be modified either by updating the numbers in the tables or by clicking on a color bar (fourth column) representing the defined color.
- Modification of the Selection colors. Press the Selection button to start the color selection dialog.
- Modification of the Mask colors. Press the Mask button to start the color selection dialog.
Some actions are available for the colors of materials. These actions are available via a popup menu called using the right mouse button click above the upper table. | |

Built-in color palettes
There are several built-in palettes for coloring materials of models are available. The palettes may be selected using the Palette and Number of colors comboboxes. The Default color palette was selected so that each color appears as a distinctive shade to color-blind users.
Description of palettes:

Update Font size and font name
It is possible to modify the font size and font name for the MIB. Please use one of the following options:
- Select Font button to start a standard font selection dialog
- Font size edit box, to change default font size for all text panels
- Font size for dir contents, to change the font size for the list of files in the Directory Contents panel.
