## 🖼️ Image Processing Nodes

### 🎨 Image Glitcher

Create authentic glitch art effects with chromatic aberration and scanlines!

Based on the HTML image glitcher by Felix Turner ([original demo](https://www.airtightinteractive.com/demos/js/imageglitcher/)).

![image](https://github.com/chrish-slingshot/ComfyUI-ImageGlitcher/assets/117188274/b7b509a4-026e-4b03-98f3-70c10ec54a19)

**Parameters:**
- **glitchiness** (0-100): Controls glitch corruption and chromatic aberration intensity
- **brightness** (0-100): Brightens the image, useful with scanlines enabled
- **scanlines** (toggle): Adds authentic CRT TV scanlines

**Usage:** Simply connect an image input and adjust parameters to taste.

![ComfyUI_temp_cknmh_000362_](https://github.com/chrish-slingshot/ComfyUI-ImageGlitcher/assets/117188274/386ed082-d551-4520-ab9e-2c8fd4063f81)

### 🌈 Color Stylizer

Selective color isolation - pick a single color and desaturate everything else!

Perfect for creating dramatic color pop effects like in *Sin City* or *Schindler's List*.

![srg_sdxl_preview_temp_utykd_00003_](https://github.com/chrish-slingshot/CrasHUtils/assets/117188274/828fe8f6-c225-490d-be60-820cfc73d1dd) ![ComfyUI_temp_tsubu_00004_](https://github.com/chrish-slingshot/CrasHUtils/assets/117188274/7faea8aa-b931-46f3-86b8-7b17432ad46e)

**Parameters:**
- **target_color**: The color to preserve (hex or RGB)
- **tolerance**: How closely colors must match to be preserved
- **desaturation**: How much to desaturate non-matching colors

**Usage:** Connect an image and specify which color to keep while everything else becomes grayscale.

## 📐 SDXL Workflow Nodes

### 📏 SDXL Resolution Picker

Choose from **all** pre-trained SDXL resolutions in one convenient dropdown!

Unlike other resolution pickers, this includes the **complete** list of SDXL-trained resolutions for optimal quality.

![image](https://github.com/chrish-slingshot/CrasHUtils/assets/117188274/4ac8d27c-4a6c-4ec0-b5c0-5e70ae7738ee) ![image](https://github.com/chrish-slingshot/CrasHUtils/assets/117188274/6e919da0-9f00-423d-b2da-6f7eabf11b62)

**Features:**
- All official SDXL resolutions (1024×1024, 1152×896, 1216×832, etc.)
- Aspect ratio labels
- Portrait, landscape, and square formats
- Single selection output

**Why use this?** SDXL was trained on specific resolutions - using them gives better results than arbitrary sizes!

---

### ✂️ SDXL Resolution Split

Split SDXL Resolution output into separate width and height values.

![image](https://github.com/chrish-slingshot/CrasHUtils/assets/117188274/9b3cb55f-ecc8-444d-8657-74cf652c2fba)

**Purpose:** Reduces workflow clutter by passing resolution as a single connection, then splitting where needed.

**Usage:**
1. Connect SDXL Resolution Picker output to this node
2. Get separate width and height outputs
3. Connect to your Empty Latent Image or other nodes

**Benefit:** One connection instead of two = cleaner workflow graphs!
