Channels, colors & contrast¶

The image viewer lets you control exactly how the image channels are displayed, so you can pull out the signal that matters.

Channels and presets¶

For multi-channel fluorescence (mIF) images, the viewer exposes the image's channels as presets (tabs such as preset 1, 2, 3, …) at the top of the image controls. Select a preset to compose the channels you want to view. The Channels layer shows how many channels the current image has and lets you adjust the overall channel opacity.

Contrast and brightness¶

Use the per-channel contrast and brightness controls to optimize signal visibility. This is especially useful in fluorescence images where different markers have different intensities.

Pseudo-color¶

Apply pseudo-colors to distinguish overlapping markers. Assigning distinct colors to channels makes co-expression patterns in multiplexed panels easier to interpret.

How it fits together¶

The Image controls panel groups these adjustments alongside the overlay and annotation layers, so you can compose the exact view you want and toggle layers on and off. See Viewing slides for the overall layout.
