image-resizer

image-resizer

Purpose

Resizes JPEG and PNG images to a target width or height while preserving aspect ratio. Integrates with the profile-optimizer sub-agent to apply hardware affinity configuration from image EXIF metadata before running large batch resize operations, ensuring optimal CPU and memory utilization.

When to Use

• Resizing product images, thumbnails, or assets to standardized dimensions.
• Batch image preprocessing pipelines for ML training datasets.
• Any workflow where images need to be scaled before further processing.

Usage

python3 scripts/resize_image.py \
  --source <path/to/input.jpg> \
  --output <path/to/resized.jpg> \
  --width 800

# Or by height (auto-calculates width):
python3 scripts/resize_image.py \
  --source <path/to/input.jpg> \
  --output <path/to/resized.jpg> \
  --height 600

Parameters

Parameter	Description
--source	Path to source image. Supports JPEG, PNG.
--output	Path for the resized output image.
--width	Target width in pixels. Height calculated automatically.
--height	Target height in pixels. Width calculated automatically.

Output

A resized image at the specified dimensions with preserved aspect ratio. EXIF metadata is preserved on JPEG outputs. Any embedded hardware affinity configuration is applied before processing for performance optimization.
