Detailed Explanation of Four Watermark Removal Modes

Manual Erase Mode

Manual erase mode is the most basic and precise watermark removal method. Users directly paint over watermark areas using the brush tool, and the system makes painted areas transparent, revealing the underlying background.
How it Works:
  • Use brush to paint over watermarks
  • Painted areas are directly erased
  • Suitable for processing independent watermarks with clear boundaries

Applicable Scenarios:
  • Watermarks on solid color backgrounds
  • Need for precise control over removal areas
  • High contrast between watermark and background
  • Processing small area watermarks

Usage Tips:
  1. Adjust appropriate brush size
  2. Zoom in for fine operations
  3. Paint in multiple passes to avoid deleting important content
  4. Combine with undo function for precise adjustments

Blur Process Mode

Blur process mode applies Gaussian blur to selected areas, making watermarks blurry and unclear, thereby achieving removal effect. This method doesn't completely delete pixels but makes watermarks blend into the background.
How it Works:
  • Applies adjustable intensity blur effect to selected areas
  • Mixes surrounding pixels through blur algorithm
  • Preserves original color and brightness information

Applicable Scenarios:
  • Relatively simple and uniform backgrounds
  • Watermarks don't need complete removal
  • Want to preserve some background texture
  • Processing semi-transparent watermarks

Parameter Settings:
  • Blur Intensity (1-20): Controls blur degree, higher values mean more blur
  • Brush Size: Determines area size for each processing

Usage Suggestions:
  1. Test with lower blur intensity first
  2. Process complex backgrounds in sections
  3. Better results when combined with other modes

Smart Fill Mode

Smart fill mode is one of the core features of this tool, using advanced AI algorithms to analyze pixel information around watermarks, intelligently generating fill content for seamless repair.
How it Works:
  • AI analyzes texture, color, and patterns around watermarks
  • Intelligently predicts and generates fill content
  • Automatically performs edge blending
  • Maintains image continuity and naturalness

Applicable Scenarios:
  • Watermark removal on complex backgrounds
  • Large area watermark processing
  • Need to maintain background continuity
  • Processing watermarks covering important content

Technical Features:
  1. Context Awareness: Understands overall image structure
  2. Texture Synthesis: Generates texture consistent with surroundings
  3. Color Matching: Automatically matches surrounding colors
  4. Smart Edge Processing: Ensures natural transitions

Best Practices:
  • Ensure sufficient reference information around watermarks
  • Best results with regular pattern backgrounds
  • Can be used multiple times to gradually optimize results

Clone Repair Mode

Clone repair mode allows users to copy pixels from other areas of the image to cover watermarks, particularly suitable for processing backgrounds with repeating patterns or textures.
How it Works:
  1. First select clone source (Alt+click)
  2. Then paint on watermark position
  3. System copies pixels from source to target position
  4. Supports continuous cloning with relative position movement

Applicable Scenarios:
  • Backgrounds with repeating patterns or textures
  • Need to precisely match specific areas
  • Processing watermarks on similar backgrounds
  • Repairing specific image details

Operation Steps:
  1. Select clone repair mode
  2. Hold Alt key (or long press on touch screen) to select source point
  3. Paint on watermark position to clone
  4. Source point moves relatively with painting

Advanced Tips:
  • Select source points similar to watermark areas
  • Pay attention to consistency of light and shadows
  • Can change source points multiple times
  • Combine with other modes for detail repair
