# Make Snapshot

Back to MIB | User interface | Menu | File

## Overview

This dialog provides access to different settings for making snapshots.

## Target

Define the destination for the rendered snapshot:

- File: save the snapshot to a file.
- Clipboard: copy the snapshot to the system clipboard.

## Crop

- Full image: make snapshot of the whole image.
- Shown area: make snapshot of the displayed in the Image View panel area only.
- ROI: use selected ROI (the ROI may be defined using the ROI panel) as area for the snapshot.

## Resize

- Width modifies width of the snapshot, or the width of a single panel when the Split channel mode is enabled.
- Height modifies height of the snapshot, or the height of a single panel when the Split channel mode is enabled.
- Resizing method select one of possible resizing methods.

List of image resizing methods

- nearest: nearest-neighbor interpolation; the output pixel is assigned the value of the pixel that the point falls within. No other pixels are considered; best for upsampling of the images.
- bilinear: bilinear interpolation; the output pixel value is a weighted average of pixels in the nearest 2-by-2 neighborhood.
- bicubic: bicubic interpolation; the output pixel value is a weighted average of pixels in the nearest 4-by-4 neighborhood; best for downsampling of the images.

- Bin: when checked, the bin2, bin4, and bin8 buttons reduce image size; otherwise, they become mag2, mag4, and mag8 and increase the image size.
- bin2/mag2: update the dimensions of the snapshot after decreasing/increasing the image size in 2 times.
- bin4/mag4: update the dimensions of the snapshot after decreasing/increasing the image size in 4 times.
- bin8/mag8: update the dimensions of the snapshot after decreasing/increasing the image size in 8 times.

## Options

- Split channel: generate a montage image, where each panel has only one color channel.

- The dimensions of the montage image can be specified using the Cols (number of horizontal panels) and Rows (number of vertical panels) edit boxes.

- In addition, it is possible to force rendering of individual color channels in the grayscale mode (the Grayscale checkbox).

Split channel example

- White Bg: render background in white color for the split channel mode and the scale bars.
- Scale bar: add a scale bar to the snapshot.

Scale bar

Note! if the width of the snapshot is too small the scale bar is not generated.

- Measurements: add the displayed measurements to the snapshot.

Measurements

Warning! The resulting image may have border artifacts, at least in MATLAB R2014b. The snapshot is done using the export_fig function written by Oliver Woodford and Yair Altman.

- Options: define visualization options for the measurements.

## Format

Select one of the possible formats:

- BMP: windows Bitmap (BMP); 1-bit, 8-bit, and 24-bit uncompressed images.
- JPG: joint Photographic Experts Group (JPEG), 8-bit, 12-bit, and 16-bit Baseline JPEG images.
- PNG: portable Network Graphics (PNG) format.
- TIF: baseline Tagged Image File Format images, including 1-bit, 8-bit, 16-bit, and 24-bit uncompressed images.
