# MIB Toolbar

Back to MIB | User interface

Quick access to frequently used functions in Microscopy Image Browser (MIB).

## Overview

The Toolbar under the main menu provides fast access to essential functions in MIB.

## Toolbar buttons

### Paste dataset from the system clipboard

Pastes an image from the system clipboard using the IMCLIPBOARD function by Jiro Doke (MathWorks, 2010).

### Virtual mode switch

Toggles between memory-resident mode (default, full dataset in memory) and virtual mode (hard drive-resident, HDD icon shown) for browsing large datasets.
Supports HDF5 and Bio-Formats files (enable Bio in the Directory Contents panel).

Warning

Segmentation in the virtual mode is limited, supporting only Annotations and 3D Lines for segmentation since MIB 2.40.

### Development shortcut...

Reserved for development purposes.

### Save model

Saves the model to a MATLAB file without prompting for a name, using:

- Default template: `Labels_NAME_OF_THE_DATASET.model` or
- Name from last used Save model as... or
- Name from a prior Load model action

Also accessible via Menu → Models → Save model.

### Zoom in

Increases magnification by 1.5x.

### 1:1

Sets magnification to 100%.

### Fit to screen

Fits the image to the Image View panel.

### Zoom out

Decreases magnification by 1.5x.

### Fast pan mode

Enables fast panning (moving the image in the Image View panel) with .

Info

Normally, panning fetches the full-sized image, causing lag for large images. The Fast pan mode reduces lag but hides the full image during panning.

### Undo

Restores the previous dataset state (use also `Ctrl`+`Z`).
Demo

Set undo history length in Menu → File → Preferences → Backup and Undo.

### Redo

Reapplies the last undone action.

### Make snapshot

Start a dialog to captures the current slice.
See more details.

Make snapshot dialog

### YX, YZ, or XZ

Switches viewing plane (default: XY).
Demo

Use shortcuts with the mouse over the intersection of colored lines (see below):
- `Alt`+`1`: XY plane
- `Alt`+`2`: ZX plane
- `Alt`+`3`: ZY plane

Warning

Some segmentation tools may only be applied to the dataset in the XY orientation.

Example of a dataset in different orientations

### Line measure tool

Measures linear distances.
See more Menu → Tools → Measure length.

### Interpolation type

Sets interpolation for shapes or lines.
See more Menu → Selection.

### Type of image resizing for visualization

Adjusts image resizing for display

Demo 1
Demo 2

Depending on the selected state:

- nearest - fastest, raw pixels, best for zoomed-in views
- bicubic - slowest, smooth, best for zoomed-out views
- automatic - when zoom value is below 100% the bicubic resizing is used, when zoom is above 100% the nearest resizing is used.

### Center marker toggle

Toggles the center marker on the image axes, useful for graphcut segmentation in grid mode.

### Block-mode switch

Applies filters only to the visible dataset portion when enabled, speeding up performance for testing.

Warning

Incompatible with ROIs (full dataset used when ROIs are active).

### Show ROI switch

Toggles ROIs visibility.

### Volume Rendering

Renders the dataset using shear-warp transform (best for small datasets).
Demo

Warning

- Invert electron microscopy data for proper visualization.
- It is recommended to use newer 3D volume viewer for better and hardware accelerated visualization.)

### Turn on parallel processing

Manually enable MATLAB parallel processing (requires Parallel Computing Toolbox).

Info

Typically unnecessary as MIB starts parallel processing automatically in many tasks.

### Swap left and right mouse button

Swap left and right mouse button

- when the button is pressed (default):
  - - interact with segmentation tools, i.e. brush
  - - pan image left/right and up/down
- when the button is unpressed:
  - - pan image left/right and up/down
  - - interact with segmentation tools, i.e. brush

Also configurable in Menu → File → Preferences → User interface.

### Mouse wheel modes

Tweaks the mouse wheel operation mode

- when the button is pressed (default)
  - mouse wheel changes slices of the dataset or time frames with holding `Alt`
  - zoom-out with `Q` and zoom-in with `W`
- when the button is unpressed:
  - mouse wheel zooms in and out of the image
  - changes slices with with `Q` for previous and `W` for next slice

Also configurable in Menu → File → Preferences → User interface.
