Image Data Converter

Build a utility that converts raw image data into HEIF format and extracts basic image properties.

Capabilities

Convert raw RGB data to HEIF

Your utility should accept raw RGB pixel data along with image dimensions and convert it to HEIF format.

• A function accepts RGB mode, size (800, 600), and raw bytes data, returning a file object in HEIF format @test
• A function accepts RGBA mode, size (400, 300), and raw bytes with alpha channel, returning a HEIF file @test

Extract image properties from created files

After creating a HEIF file from raw data, the utility should be able to extract and return the image properties.

• Extract size property from a HEIF file created from raw RGB data, returning (width, height) tuple @test
• Extract color mode from a HEIF file created from raw RGBA data, returning the mode string @test
