Image Format Converter

Purpose & User Intent: This tool solves the problem of converting FCM image assets to the JPG format. It targets designers, developers, and operations teams that maintain image libraries, CMS assets, or automation pipelines needing consistent web-ready outputs. Use occurs during asset migration, format standardization, or batch conversion tasks where input is FCM and output is JPG. Core Logic & Features: The tool performs file-type validation, color-space mapping to sRGB, and JPEG encoding with user-selected quality. Required features include input FCM handling, per-file processing, and output generation. Optional features include resizing, color profile handling, metadata preservation, and batch queuing. It can emit a single JPEG per input or produce a ZIP for batches with deterministic naming. Metadata handling is configurable. Inputs & Outputs: Inputs include input_file (type: file, required, sample: example.fcm, validation: extension .fcm). quality (percentage, 1-100; default 90). resize (width x height in px; optional). color_profile (string, e.g. sRGB, AdobeRGB; optional). Outputs include output_file (type: file, format: image/jpeg, naming: same base name with .jpg) or ZIP archive for batches. Validation: non-image inputs yield errors; large files may trigger chunked processing. Algorithms & Calculations: Decoding of FCM to pixel data, color-space conversion to sRGB, JPEG encoding with specified quality, optional resizing maintaining aspect ratio, alpha-channel handling by flattening with a background color. Metadata handling follows user preference; when preserved, color profiles and basic EXIF-like data are retained if compatible. Error & Edge Cases: Invalid extension or corrupt input yields per-file error codes; unsupported color profiles are mapped to sRGB; oversized inputs trigger chunked processing or fail gracefully with partial results if allowed; missing inputs cause per-file skips. Industry/Region & Localization: Uses standard color spaces, sRGB, and JPEG baseline; assumes Unicode filenames; supports localization through language packs; currency or measurement not applicable. Assumptions & Exclusions: Assumes input is a valid FCM image asset; does not convert non-image data; not a video or multi-frame format converter; excludes non-JPG targets unless explicitly requested.
