Preview

Overview

Marks a place in the graph to view. Use it to inspect a connected image as the final result, or place several along a long graph as observation points for comparing stages. Evaluation itself writes no files. The inspector provides a one-shot PNG save action, while output nodes handle automatic and batch export.

Usage tips

• Any selected node can show a preview in the inspector, but this node makes the intended final result explicit in the graph and keeps it visible without reselection.
• To compare before and after, branch into two previews: original image → processed image → Preview and original image → Preview.
• Give label a name such as "Final" or "Check mask" to stay oriented in a large graph. Display-name priority is custom node rename → label → template name.
• Pixel art displays at native or integer scale without blur. Zoom the inspector preview to inspect details.

Common pitfalls

• No PNG is saved automatically during evaluation: this node does not write files while evaluating. Use Save as PNG in the selected Preview's inspector for a one-shot export, or an output node such as batch_export for automatic/batch export.
• Evaluation seems slow: many previews increase display-update cost. Check the Diagnostics tab in the bottom status area, then delete unused observation points or turn off their node previews.
