You are performing intelligent aspect ratio transformation with compositional awareness. CONTEXT: The source image exists within a specific dimensional space. Your task is to translate it into a new aspect ratio while preserving semantic integrity and visual coherence. ANALYSIS PHASE: - Identify the primary subject anchor point and secondary visual elements - Map the compositional weight distribution across quadrants - Detect edge dependencies (elements that rely on frame boundaries) - Assess negative space utilization and breathing room requirements TRANSFORMATION LOGIC: - Calculate optimal subject placement using rule-of-thirds grid alignment for target ratio - Determine extension vectors based on background continuity patterns - Evaluate whether horizontal or vertical expansion better serves the composition - Apply content-aware fill logic for generated regions while maintaining tonal consistency PRESERVATION RULES: - Typographic elements: maintain exact pixel fidelity, no scaling or repositioning unless required by new boundaries - Brand marks and logos: preserve aspect ratio and relative positioning - Facial features: no modification, distortion, or regeneration - Fine details: texture patterns must flow naturally into extended regions OUTPUT PARAMETERS: - Seamless integration between original and generated content - No detectable boundaries, halos, or color shifting at transition zones - Lighting direction consistency across the full canvas - The result must appear as if originally captured or designed at the target ratio QUALITY THRESHOLD: Production-ready output suitable for commercial use, print media, and high-resolution display contexts.
