	# Panorama Strip Combiner

	A Python utility that combines vertical image strips into a seamless panorama with smooth blending between overlapping regions.

	## What It Does

	This script takes a directory of vertical image strips and combines them into a single panoramic image. It features:

	- Automatic ordering of strips based on filename

This script processes a sequence of TIF images by cropping each image to a vertical strip from the center for use in slitscan image creation

	#!/bin/bash

	# This script processes a sequence of TIF images by cropping each image to a vertical strip from the center. Here's a breakdown:

	# 1. It takes images from an input directory ("frames-try1") and saves the cropped versions to an output directory ("frames-03-trial").
	# 2. The script extracts a vertical strip with a width of 105 pixels, centered in each image.
	# 3. It uses ffprobe to determine the dimensions of the first image, calculates the center, and then uses ffmpeg to crop all images in the sequence.

	# If you want to use this script, you might need to edit:
	# - `INPUT_DIR` and `OUTPUT_DIR` paths to match your folder names

This tool normalizes the loudness of MP3 audio files to a consistent level.

	"""
	This tool normalizes the loudness of MP3 audio files to a consistent level. Here's how to use it:

	Run the script with a directory path: python script.py /path/to/mp3s
	By default, it sets audio to -14 LUFS (loudness units) and prevents clipping at -0.1dB
	It creates new files prefixed with "processed_" unless you use --overwrite
	You can customize the target loudness with --target-lufs and peak limit with --threshold-db

	The tool analyzes each MP3 file, adjusts its volume to the target loudness, applies a limiter to prevent distortion, and saves the processed version.

WordPress plugin to limit editing of pages and their children to certain user roles.

	<?php

	/**
	* Plugin Name: Role-Based Page Editor Limitations
	* Description: This plugin restricts editing capabilities of specific pages to certain user roles. It dynamically creates roles if they don't exist and assigns them editor capabilities. It then checks if a user with a specific role is trying to edit a page that they're not assigned to, and if so, it removes their editing capabilities for that page. Edit the $role_page_map array to specify which roles can edit which pages.
	* Version: 1
	* Author: Greg R.

	/* For example you want to make it so that some peolple at your company can edit /subpage/ and all the children under that page, so you can create a user role that restricts them to jus that section of the site. */
