Compare Modes

Using before/after comparison views.

Short Summary

This page explains how to use Compare mode to view original and processed content side-by-side or overlaid.

What is Compare Mode?

Compare mode lets you view your original content and the processed result to evaluate the effect of your settings. This is useful for fine-tuning parameters and making before/after comparisons.

Compare Mode Options

After (Default)

  • Shows only the processed result with all effects applied.
  • This is the standard working view.

Before

  • Shows the original content without any effects.
  • Useful for checking the source material.

Split

  • Displays original on one side and processed on the other, divided by a vertical line.
  • Drag the divider line left or right to compare different regions.

Accessing Compare Mode

Using the Top Bar

  1. Look for the Compare button in the top bar.
  2. Click it to cycle through modes: After → Before → Split → After.

Keyboard Shortcut

  • Press C to toggle between compare modes.

Using Split Mode

  1. Select Split from the Compare button.
  2. A vertical line appears dividing the viewport.
  3. Left side: Original content.
  4. Right side: Processed content with effects.
  5. Click and drag the divider line to adjust the split position.
  6. Release to lock the position.

Practical Uses

Fine-tuning Effects

  1. Apply an algorithm and adjust parameters.
  2. Switch to Split mode.
  3. Move the divider to compare the same region with and without effects.
  4. Adjust settings while in Split mode to see changes immediately.

Evaluating Color Changes

  1. Apply a palette or adjust colors.
  2. Use Split or Before mode to compare color accuracy.
  3. Switch back to After to continue work.

Checking Detail Preservation

  1. Apply dithering or reduction effects.
  2. Use Split mode to verify detail retention in specific areas.
  3. Adjust algorithm parameters based on comparison.

Export Note

Exports always use the processed version (After mode), regardless of current compare mode. Before and Split modes are for preview only.

Tips

  • Use Before mode to reference original colors or composition.
  • Use Split mode when adjusting subtle parameters like brightness or contrast.
