Description

This script enhances the original creative-upscale functionality by adding batch processing capabilities. It allows you to select multiple images through a file picker dialog and process them all with the same sophisticated upscaling pipeline that combines traditional upscaling with AI diffusion techniques.

Features

• Batch Processing: Select and process multiple images at once
• File Picker Integration: Easy file selection through Draw Things' native dialog
• Mixed Resolution Support: Handles images of different sizes automatically
• Progress Tracking: Shows processing progress with time estimates
• Flexible Upscaling: Choose between 200% (2x) or 400% (4x) upscaling
• Custom Negative Prompts: Override default negative prompts for batch processing
• Fallback Mode: Processes canvas image when no files are selected
• Error Resilience: Continues processing even if individual images fail

Technical Details

Upscaling Pipeline

1. Initial Upscale: 4x UltraSharp traditional upscaler
2. AI Enhancement: Tiled diffusion using Juggernaut Reborn model
3. Detail Enhancement: Multiple LoRAs for texture and detail improvement
4. Optional 4x: Second pass for 400% total upscaling

Models Required

• 4x_ultrasharp_f16.ckpt
• controlnet_tile_1.x_v1.1_f16.ckpt
• juggernaut_reborn_q6p_q8p.ckpt
• add_more_details__detail_enhancer___tweaker__lora_f16.ckpt
• sdxl_render_v2.0_lora_f16.ckpt
• tcd_sd_v1.5_lora_f16.ckpt

Installation

1. Download create-upscale-batch.js
2. Place in your Draw Things Scripts folder:
   • macOS: ~/Library/Containers/com.liuliu.draw-things/Data/Documents/Scripts/
   • iOS/iPadOS: Use Draw Things > Presets > Manage Scripts > Add New Script
3. Restart Draw Things
4. The script will appear in your Presets menu

Usage

1. Open Draw Things
2. Go to Presets > Scripts > create-upscale-batch
3. Configure options:
   • Click "Select Images to Process" to choose your files
   • Choose upscaling factor (200% or 400%)
   • Optionally set custom negative prompt
   • Enable verbose logging if needed
4. Click "Process Images"
5. Results will be saved according to your Draw Things auto-save settings

File Selection

Navigate to your source folder (e.g., /Volumes/aia/Chute/upscale/to_upscale) and select the images you want to process. The script supports common image formats: JPG, PNG, WebP, TIFF, BMP, HEIC.

Configuration

Auto-Save Setup

Configure Draw Things auto-save to your desired output folder before running the script. All processed images will be saved to this location with appropriate suffixes (_upscaled_2x or _upscaled_4x).

Performance Considerations

• Processing time depends on image size and system capabilities
• Tiled processing helps manage memory for large images
• 400% upscaling requires significantly more processing time

Requirements

• Draw Things app (iOS, iPadOS, or macOS)
• Sufficient storage space for upscaled images
• Required models downloaded (script will auto-download if needed)
