XBM Image Editor

This tool provides a browser-based workflow for creating and editing XBM bitmaps. It supports monochrome XBM input and output, enabling pixel-level edits without desktop installation. Users include software developers embedding XBM icons, hardware engineers prototyping UI assets, and educators teaching bitmap graphics. The core value lies in immediacy, reproducibility, and integration-ready code, reducing hand-coding errors and speeding up icon design cycles.
Conceptually, XBM images are a one-bit grid. The tool translates that grid into a boolean matrix, applies operations such as toggling bits, inverting regions, and mirroring, and regenerates valid XBM source code or PNG exports. All edits preserve 1-bit depth and produce deterministic outputs suitable for C headers and embedded environments. Required features include XBM input/output, grid-based editing, and predictable bit-level results. Optional/advanced features include multi-export formats and pattern-based templates for common icons.
Inputs include a single XBM bitmap header or text data and optional export settings. Outputs include an updated XBM header/source string and an optional PNG when requested. Validation enforces 1-bit depth, consistent row lengths, and correct C array formatting. Outputs are designed for direct inclusion in code or asset pipelines.
Algorithms & Calculations: Internally, the workflow parses XBM to a 2D boolean matrix, applies bitwise edits, and reconstructs valid XBM source or PNG data. It computes line endings and ensures each scan line ends with a proper comma/line terminator to satisfy C syntax. No color processing is performed beyond 1-bit logic.
Error & Edge Cases: Invalid XBM input triggers normalization attempts or explicit error signals; missing or malformed headers default to a minimal 1-bit canvas and a warning-free export. Large images are throttled to preserve browser responsiveness. Inconsistent line widths raise corrective adjustments to maintain valid XBM syntax.
Industry/Region & Localization: Uses standard XBM conventions common in embedded and open-source graphics. Outputs follow US/ISO numeric formatting. No locale-specific currencies or regional rules apply to the bitmap domain.
Assumptions & Exclusions: Assumes input is monochrome XBM. Does not edit color bitmaps or convert between image formats beyond XBM/PNG export. UI or styling considerations are outside the specification.
