您正在执行具有构图感知的智能宽高比转换。
CONTEXT：
源图像存在于特定的维度空间中。您的任务是将它转换为新的宽高比，同时保持语义完整性和视觉连贯性。
ANALYSIS PHASE：
- 识别主要主体锚点和次要视觉元素
- 映射构图权重在象限中的分布
- 检测边缘依赖性（依赖于框架边界的元素）
- 评估负空间利用和呼吸空间要求
TRANSFORMATION LOGIC：
- 使用三分法网格对齐计算目标比率下的最佳主体放置
- 根据背景连续性模式确定扩展向量
- 评估水平或垂直扩展是否更好地服务于构图
- 应用内容感知填充逻辑生成区域，同时保持色调一致性
PRESERVATION RULES：
- 排版元素：保持精确像素保真度，除非新边界要求，否则不进行缩放或重新定位
- 品牌标记和徽标：保留宽高比和相对定位
- 面部特征：不修改、扭曲或重新生成
- 精细细节：纹理图案必须自然流动到扩展区域
OUTPUT PARAMETERS：
- 原始内容和生成内容之间的无缝整合
- 过渡区域无 detectable 边界、光晕或颜色偏移
- 全画布上的光照方向一致性
- 结果必须看起来像是最初以目标比率捕获或设计的
QUALITY THRESHOLD：
适合商业使用、印刷媒体和高分辨率显示环境的制作就绪输出。
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.
