ComfyUI Extension: ComfyUI-Image-Segmenting-Loader

# Geeky Qwen Edit - ComfyUI Segmentation & Effects Suite

Interactive image segmentation, advanced effects processing, and composition nodes optimized for workflow efficiency and transparency handling.

## Nodes Included

### 🎯 Qwen Segment Loader

Interactive image segmentation with real-time coordinate preview.

**Features:**

- Visual coordinate grid with customizable spacing

- Auto-updating preview when parameters change

- Selection rectangle with corner markers

- Info panel showing selection details

- Outputs clean cropped segments (no padding)

**How to Use:**

1. Upload your image

2. Connect coordinate\_preview output to a Preview Image node

3. Adjust coordinates (X, Y, width, height) and grid spacing

4. Run workflow to see updated grid preview

5. Fine-tune coordinates based on visual feedback

6. Process the segment with your editing nodes

**Outputs:**

- original\_image: Full original image

- segment\_image: Cropped segment (exact size, no padding)

- segment\_metadata: JSON data for compositor

- coordinate\_preview: Visual grid preview

### ✨ Qwen Effects

Advanced effects processor optimized for images with alpha channels/transparent backgrounds.

**Effects Available:**

**Drop Shadow:**

- Customizable offset, blur, opacity, and color

- Works perfectly with transparent images

**Outer Glow:**

- Adjustable radius, intensity, and color

- Creates beautiful glow effects around transparent objects

**Stroke/Outline:**

- Variable width and color options

- Clean outlines that follow alpha channel

**Color Adjustments:**

- Brightness, contrast, saturation controls

- Hue shifting (-180° to +180°)

**Blur & Sharpen:**

- Gaussian blur with alpha preservation

- Customizable sharpening strength

**Artistic Effects:**

- Emboss with strength control

- Edge enhancement

- Posterize with level control

- Noise addition

**Advanced Effects:**

- Color overlay with blend modes (normal, multiply, screen, overlay, soft light, hard light)

- Vignette with customizable strength and radius

- All effects preserve transparency

**Perfect For:**

- Post-processing background-removed images

- Enhancing segments from Geeky RemBG nodes

- Adding professional effects to transparent objects

- Creating composite-ready elements

### 🔧 Qwen Compositor

Smart compositor that handles alpha channels and properly positions edited segments.

**Features:**

- **Full Alpha Channel Support**: Properly handles RGBA images from effects processing

- Automatic scaling and positioning from metadata

- Multiple blend modes (normal, multiply, screen, overlay, soft light)

- Opacity control and edge feathering

- **Transparency-Aware**: Works seamlessly with background-removed images

**Blend Modes:**

- Normal: Standard compositing

- Multiply: Darkening blend

- Screen: Lightening blend

- Overlay: Contrast enhancement

- Soft Light: Subtle lighting effects

## Typical Workflows

### Basic Segmentation Workflow:

Image Input → Qwen Segment Loader → \[Your Editing Nodes] → Qwen Compositor → Final Output

### With Background Removal & Effects:

Image Input → Qwen Segment Loader → RemBG Node → Qwen Effects → Qwen Compositor → Final Output

### Professional Effects Chain:

Segment → RemBG → Effects (Drop Shadow + Glow + Color Adjust) → Compositor

## Alpha Channel Handling

This suite is specifically designed to work with transparent images:

- **Segment Loader**: Outputs clean segments ready for alpha processing

- **Effects Node**: All effects preserve and enhance alpha channels

- **Compositor**: Intelligent alpha compositing with proper blending

## Grid Preview Features

The coordinate preview shows:

- White grid lines with customizable spacing (25-200px)

- Gold coordinate numbers on all edges

- Bright pink selection rectangle with corner markers

- Info panel showing selection details and grid spacing

- Auto-update status indicator

## Tips for Best Results

1. **Use the coordinate preview** to precisely select your areas of interest

2. **Enable auto-preview** for real-time feedback while adjusting coordinates

3. **Chain effects** in the Effects node for complex processing

4. **Experiment with blend modes** in the compositor for creative results

5. **Use alpha-aware workflows** for professional transparency handling
