Create Mosaic

Node Icon

Creates a 2D mosaic layout from a multi-slice or multi-channel image/mask. The mosaic arranges the slices or channels in a grid pattern with a specified number of columns. This is useful for visualizing multiple slices or channels simultaneously in a single 2D view.

Inputs

Input

The image or mask to create a mosaic from. Can be either a single image/mask or a list of images/masks.

Type: Image List, Mask List, Required, Single

Outputs

Output

The resulting mosaic image/mask. If the input is a list, outputs a list of mosaic images/masks.

Type: Image, Mask

Settings

Number of Columns Integer

Specifies how many columns the mosaic should have. The slices/channels will be arranged row by row, filling each row with this many columns before starting a new row.

Default: 5 Minimum: 1 Can be connected as input: Yes

Dimension Selection

Specifies whether to create the mosaic from slices or a specific channel.

Values: Slice, Channel Default: Slice

Channel Integer

When Dimension is set to “Channel”, specifies which channel to use for creating the mosaic. Only visible when Channel dimension is selected.

Default: 0 Minimum: 0 Can be connected as input: Yes Visibility: Only when Dimension = Channel

Details

The node processes the input in the following steps:

Splits the input along the selected dimension (slices or specified channel)
Arranges the split parts into rows based on the specified number of columns
Combines the arranged parts into a single 2D mosaic image/mask

Example Uses

Viewing multiple slices of a 3D image in a single 2D layout
Comparing different channels of a multi-channel image in a grid view
Creating thumbnail grids of image sequences
Generating overview visualizations of 3D or multi-channel data
