DDS BC7 Viewer

DDS BC7 Viewer is a domain-focused analysis tool that helps graphics programmers, engine engineers, and texture artists inspect textures compressed with BC7 inside DDS containers. It reads the file header, confirms BC7 compression, records texture dimensions, mip-map count, and format flags, and surfaces a structured view of the asset's properties for validation and optimization workflows.
Conceptually, the tool separates parsing, validation, and optional decoding. It computes the number of BC7 blocks from width and height (blocks = ceil(width/4) × ceil(height/4)) and aggregates per-block statistics to reveal compression behavior, color distribution, and potential artifacts. If decoding is enabled, it maps BC7 blocks to an RGBA buffer and provides a pixel-accurate preview without modifying the original file.
Who benefits: graphics programmers integrating texture pipelines, tool operators validating assets during import, and artists inspecting compression quality before export. The tool's value lies in robust BC7 handling, precise metadata extraction, and automation-friendly outputs that feed asset catalogs and build systems.
Core features include header validation, BC7 block counting, optional BC7 decoding, metadata extraction, and export options for JSON, PNG, or summarized reports. The tool is designed for performance and reliability in automated pipelines, with deterministic results and clear error data for failure analysis.
