AI一键转墨线画：创意速写风格，极简黑白高对比

一键将图片转换为高对比度墨线画，模拟传统速写风格，细节丰富，极简留白，非常适合创意插画和艺术设计。 { "prompt_template": "A detailed ink drawing based on {argument name=\"image reference\" default=\"[insert image reference here]\"}, isolating the main subject. Rendered in a traditional micron pen sketchbook style. Shading, texture, and patterns are achieved exclusively through dense cross-hatching and fine line work, using high contrast black ink on textured white paper. The subject is centered with vast negative space, completely removing the original photo's background." } 插画 草图 / 线稿 人像 / 自拍 摘要 / 背景 nanobanana
