Image View Panel

Back to MIB | User Guide | Panels

Overview

The Image View Panel displays slices of the opened dataset, allowing you to visualize your images in XY, ZX, or ZY orientations. The orientation is selected via the Toolbar.
On the left side, a slider and edit box let you navigate through slices—though these are hidden for single-slice datasets.

Image layers in MIB

Image layers in MIB

The Image View Panel can simultaneously display multiple layers, each serving a distinct purpose:

  • Grayscale or multichannel image: Shows the original image being analyzed, in grayscale or multichannel format.
  • Model layer: Displays segmented model materials or a difference map for correlation analysis. See Data Layers for details.
  • Mask layer: A black-and-white (bitmap) mask generated by filters, used as a source for shapes in segmentation or for local black-and-white thresholding with the BW Thresholding tool.
  • Selection layer: A temporary layer for segmentation, easily modified before transferring to the Mask or Model layers.
  • ROI layer: Shows Regions of Interest (ROIs) when enabled, allowing focused selection and analysis within the image.

MIB Layers

You can adjust the colors and transparency of the Model, Mask, and Selection layers using sliders in the View Settings panel or the Menu -> File -> Preferences -> Colors and styles (Menu -> File -> Preferences -> Colors).
