Two-Image Merge Editor

This tool accepts two source images and produces a single merged output. It is designed for content creators, marketers, and designers who need a quick composite for proofs, social visuals, or client reviews. The domain logic validates common formats, resizes inputs to a shared canvas, and blends pixels using a selected method. It also handles color management to minimize banding.
Core capabilities include two file inputs, alignment options (horizontal, vertical, or centered overlap), and a set of blend modes (normal, multiply, screen, overlay) to control how pixels combine at the seam. The tool supports automatic canvas sizing to the larger input with optional safe cropping and aspect-ratio preservation. Optional features such as feathered edges or soft masks can be applied conceptually in downstream steps; previews help refine the merge. Output formats include PNG and JPEG with adjustable quality. The system records basic metadata for audit in pipelines.
Error handling focuses on data integrity: missing inputs, unsupported formats, or excessively large files produce structured error signals. The approach assumes standard RGB color space (sRGB) and 8-bit channels. The tool is suitable for workflows in marketing, editorial, and creative production, enabling fast iteration while preserving image quality.
Industry standards include sRGB color space and pixel-based dimensions; localization is achieved via language packs, with no region-specific regulations impacting the merge operation. Assumes licensed or permitted source images; excludes color grading, retouching, or multi-layer compositing beyond the merge seam.
