用途

Qwen-Image-2.0-Pro 是一个专业图像生成技能,通过 inference.sh 的命令行工具 belt(CLI)调用 Alibaba Qwen-Image-2.0-Pro 模型。其定位适合专业文字渲染和复杂设计,典型用途包括带文字的海报、营销横幅、标志设计等文字与图像结合的场景。

专业模型能力

  • 专业文字渲染:支持多行及段落级文字,细节精细。
  • 细颗粒度写实:更好的纹理与照片级场景。
  • 更强的语义遵循:更准确地跟随复杂提示词。
  • 复杂设计:适合文字加图像的组合。

安装与登录

需先安装 belt CLI 技能:

npx skills add belt-sh/cli

随后登录:

belt login

使用方式

基本调用:

belt app run alibaba/qwen-image-2-pro --input '{"prompt": "Poster with title \"Welcome!\" in bold blue text"}'

文本转图像示例:

belt app run alibaba/qwen-image-2-pro --input '{
  "prompt": "A futuristic cityscape at sunset with flying cars"
}'

文字密集型海报示例:

belt app run alibaba/qwen-image-2-pro --input '{
  "prompt": "Healing-style hand-drawn poster featuring three puppies playing with a ball. The main title \"Come Play Ball!\" is prominently displayed at the top in bold, blue cartoon font. Below, the subtitle \"Join the Fun!\" appears in green font.",

}'

图像编辑(风格迁移)示例:

belt app run alibaba/qwen-image-2-pro --input '{
  "prompt": "Make the person from Image 1 wear the outfit from Image 2",
  "reference_images": [
    {"uri": "https://example.com/person.jpg"},
    {"uri": "https://example.com/outfit.jpg"}
  ],
  "num_images": 2
}'

可复现生成示例:

belt app run alibaba/qwen-image-2-pro --input '{
  "prompt": "Abstract geometric art in blue and gold",
  "seed": 12345
}'

工作流示例:

# 1. 生成示例输入以查看所有选项
belt app sample alibaba/qwen-image-2-pro --save input.json

# 2. 编辑提示词
# 3. 运行
belt app run alibaba/qwen-image-2-pro --input input.json

Python SDK 示例:

from inferencesh import inference

client = inference()

# Text-heavy poster
result = client.run({
    "app": "alibaba/qwen-image-2-pro",
    "input": {
        "prompt": "Poster with title \"Welcome!\" in bold blue text at top",
        "width": 1024,
        "height": 1536,
        "prompt_extend": False
    }
})
print(result["output"])

# Stream live updates
for update in client.run({
    "app": "alibaba/qwen-image-2-pro",
    "input": {
        "prompt": "Professional product photography of a watch"
    }
}, stream=True):
    if update.get("progress"):
        print(f"progress: {update['progress']}%")
    if update.get("output"):
        print(f"output: {update['output']}")

输入选项

参数 类型 说明
prompt string 必填。要生成或编辑的内容(最多 800 字符)
reference_images array 用于编辑的输入图像(1-3 张)
num_images integer 要生成的图像数量(1-6)
width integer 输出宽度,像素(512-2048)
height integer 输出高度,像素(512-2048)
watermark boolean 添加 "Qwen-Image" 水印
negative_prompt string 要避免的内容(最多 500 字符)
prompt_extend boolean 启用提示词重写(默认:true)
seed integer 用于复现的随机种子(0-2147483647)

尺寸约束:总像素必须在 512×512 与 2048×2048 之间。

输出

字段 类型 说明
images array 生成或编辑后的图像(PNG 格式)
output_meta object 包含尺寸和数量的元数据

文字渲染技巧

为在 Pro 模型上获得最佳文字效果:

  • 使用引号包裹精确文字:"Title: "Hello World!""
  • 指定字体细节:颜色、样式、大小、位置
  • 关闭 prompt_extend:设置 prompt_extend: false 以获得精确控制
  • 使用负面提示词:"blurry text, distorted text, low quality"

示例提示词结构:

Poster with the title "GRAND OPENING" in large red serif font at the top center.
Below, the date "March 15, 2024" in smaller black text.
Background: elegant gold and white gradient.
Style: professional, clean, modern.

推荐负面提示词:

{
  "negative_prompt": "low resolution, low quality, deformed limbs, deformed fingers, oversaturated, waxy, no facial details, overly smooth, AI-like, chaotic composition, blurry text, distorted text"
}
