BMP Validator

BMP Validator provides automated assessment of BMP file structure against the official bitmap file and DIB header specifications. It targets developers, QA teams, and digital asset managers who ingest legacy images or migrate assets. It detects malformed headers, inconsistent sizes, and invalid color depth that commonly cause runtime errors or rendering issues in image pipelines. The tool is designed for batch and single-file validation in asset workflows.
Conceptually, the tool treats a BMP as a header region, a color palette (when required), and a pixel data region aligned to 4-byte boundaries. It reads the file, interprets the BITMAPFILEHEADER and the chosen BITMAPINFOHEADER variant, then computes expected dimensions, palette counts, and pixel array offsets. It flags mismatches, missing palette data for indexed bit depths, and invalid compression codes, returning a structured report that consumers can parse to decide remediation steps. Unique differentiators include deep header- and palette-aware validation, explicit error codes, multi-variant DIB header support, and precise offset reporting for remediation.
Use cases include pre-ingest checks for image processing platforms, automated asset QA before CDN deployment, and data migration projects where BMPs are legacy assets. The tool outputs a machine-readable JSON report intended for integration into CI pipelines, asset management systems, or metadata catalogs. It helps teams detect and triage BMP issues early, reducing processing errors and asset churn.
