📋 Features

🖼️ Resolution Nodes

Simple Size Picker

• 30+ Standardized Resolutions (512px to 8K):
  • ✅ Square (1:1) – 512×512 to 2048×2048
  • ✅ Portrait (2:3, 9:16) – 512×768 to 1080×1920
  • ✅ Landscape (16:9, 3:2) – 768×512 to 3840×2160 (4K)
  • ✅ Ultra-Wide (21:9, 32:9) – 2560×1080 to 7680×2160
  • ✅ Exotic Ratios (e.g., 9600×1200 at 8:1)
• User-Friendly:
  • Categorized dropdown menu with tooltips
  • Zero-configuration workflow integration

Empty Latent Size Picker (Extended Version)

• All features of Simple Size Picker PLUS:
• 🚀 Auto-Generated Latent Output:
  • Directly connects to samplers
  • Eliminates manual "Empty Latent Image" nodes
  • Preserves selected dimensions in latent space

📝 Prompt Engineering Node

Create Prompts With Text From File

• Batch Prompt Generation:
  • 🔄 Combine base text with dynamic content from files
  • 🎛️ Control output quantity with results parameter
• File-Based Variability:
  • Supports .txt files with line-separated entries
  • Random line selection for diverse outputs
• Use Cases:
  • Character variations (e.g., "a portrait of [name_from_file]")
  • Style mixing ("in the style of [artist_from_file]")
  • Batch testing different descriptors

Create Prompts With Text From File

• Supported Formats:
  • .txt (line-delimited)
  • .csv (first column)
• Advanced Parameters (For Create Prompts With Text From File node)

| Parameter | Type/Options | Description | Example Usage | |---------------|-------------------------------|-----------------------------------------------------------------------------|----------------------------------------| | next_line | increment | decrement | random | fixed | Defines how to select the next line from the file:<br>- increment: Sequentially moves forward<br>- decrement: Sequentially moves backward<br>- random: Picks lines randomly<br>- fixed: Always uses the same line (requires start_line) | random (for varied prompts) | | start_line | Integer (0-based) | Sets the starting line offset in the file.<br>- Only affects increment/decrement/fixed modes.<br>- If fixed mode is selected, this line will be used for all prompts. | 10 (skips first 10 lines) | | results | Integer (≥1) | Controls the number of generated prompts (lines to process).| 3 (outputs 3 prompts) |

• File Requirements:

  • Text file must have at least start_line + results lines for sequential modes.
  • Empty lines are skipped automatically.

• Behavior Examples:

  • next_line=increment, start_line=5, results=3 → Lines 5, 6, 7
  • next_line=random, results=5 → 5 random lines
  • next_line=fixed, start_line=2 → Only line 2 (repeated for all prompts)
