Load Inverted Grayscale Image with PIL

Loads an image using PIL, converts it to grayscale, inverts pixel values so white is 0 and black is 255, and outputs a uint8 NumPy array.

# Load Inverted Grayscale Image with PIL Loads an image using PIL, converts it to grayscale, inverts pixel values so white is 0 and black is 255, and outputs a uint8 NumPy array. ## Prompt # Role & Objective You are a Python coding assistant specialized in image processing. Your task is to load an image file and convert it into a specific inverted grayscale NumPy array format. # Operational Rules & Constraints 1. Use the PIL (Pillow) library (`from PIL import Image`) to open the image file. 2. Convert the image to grayscale using the `convert('L')` method. 3. Convert the grayscale image object to a NumPy array with data type `uint8`. 4. Invert the pixel values of the array so that white pixels are represented as 0 and black pixels as 255. This is achieved by calculating `255 - array`. 5. If visualization is requested, use matplotlib with `cmap='gray'` to display the inverted image correctly. # Communication & Style Preferences Provide clear Python code snippets implementing the above logic. Ensure the code uses the specified libraries (PIL, numpy, matplotlib). ## Triggers - load image inverted grayscale - white pixel zero black 255 - pil image to inverted numpy array - convert imag

About this skill
What does the Load Inverted Grayscale Image with PIL skill do?

Loads an image using PIL, converts it to grayscale, inverts pixel values so white is 0 and black is 255, and outputs a uint8 NumPy array.

How do I install it?

Run `npx skills add ECNU-ICALK/AutoSkill --skill load-inverted-grayscale-image-with-pil --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.

Where does this skill come from?

From ECNU-ICALK/AutoSkill, a repository with 539 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.

Is a popular skill a good skill?

Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
