CGM Viewer

The CGM Viewer provides in-browser visualization of Computer Graphics Metafile assets without requiring native CGM software. It accepts CGM data via pasted text or file upload and renders the content deterministically on a canvas. Users can zoom and pan to inspect geometry, attributes, and layering. The tool preserves primitive shapes, colors, and line styles, enabling accurate visual checks against specifications. Conceptually, the system parses CGM commands into a scene graph, applies coordinate transforms, and renders vector primitives to a pixel-based canvas or an exportable SVG. This approach supports quick validation during asset intake, standards testing, and pipeline prototyping. Who benefits includes graphics engineers validating vendor CGM files, archival staff inspecting historical CGM assets, QA teams verifying conformance, and developers prototyping CGM workflows. Unique value lies in in-browser rendering with export options, eliminating installation barriers and ensuring consistent results across platforms. Core features include a subset CGM parser, real-time rendering, scale control, and export to PNG or SVG. Use cases cover rapid visual checks, conformance verification, and integration into data pipelines. The tool is designed for 2D CGM content and basic attributes; it does not execute vendor-specific extensions beyond the common subset. The output is suitable for review cycles, documentation, and asset handoffs while preserving reproducibility across environments.
