Este es un proceso de dos pasos: crear una tarea y luego recuperar el resultado.

Nota

  • Para llamadas asíncronas, establezca el parámetro de encabezado X-DashScope-Async en enable.
  • El task_id para una tarea asíncrona es válido durante 24 horas. Después de que caduque, el estado de la tarea se convierte en UNKNOWN.

Paso 1: Enviar una solicitud para crear una tarea

Esta solicitud devuelve un ID de tarea (task_id).

    },
    "request_id": "4909100c-7b5a-9f92-bfe5-xxxxxx"
}

Paso 2: Consultar el resultado por ID de tarea

Utilice el task_id obtenido en el paso anterior para sondear el estado de la tarea a través de la API hasta que el task_status sea SUCCEEDED o FAILED.

Ejemplo de solicitud

Reemplace {task_id} con el valor task_id devuelto por la llamada a la API anterior. El task_id es válido para consultas durante 24 horas. Reemplace {WorkspaceId} con su ID de espacio de trabajo real.

Caso 2: Diseño visual

Image 1: A commercial-grade product photography main visual cover image, front-view panoramic composition. A pair of retro-futuristic wireless over-ear headphones floats above a geometric plaster form, showcasing perfect symmetrical aesthetics. The materials are champagne gold metal and a cream-white shell. The background is a deeply blurred warm indoor light and shadow, with soft light outlining the product's silhouette. The white space in the image creates a strong sense of breathability, suggesting a quiet auditory experience. 8k ultra-high resolution, minimalist and premium feel.
Image 2: A 100mm macro shot of the product's material details, focusing closely on the connection of the headphone's telescopic arm. It clearly shows the texture of the champagne gold brushed aluminum alloy and the CNC precision-cut chamfers. A sharp backlight creates a starburst highlight on the metal edge. The background is dark to emphasize the industrial precision of the metal. The image quality is extremely sharp with no noise.
Image 3: An extreme close-up macro shot of the material, focusing on the surface of the mocha-colored protein leather earcups. Side lighting reveals the fine pore texture of the leather, the soft wrinkles from pressing, and the ventilation hole details, conveying ultimate skin-friendly comfort and resilience. The light and shadow are rich in layers, and the color tone is warm and moist. Ultra-high-definition macro photography.
Image 4: An artistic exploded view of the product, showing the internal sound units, noise-canceling chips, battery modules, and external walnut wood decorative panels and metal frame of the retro-futuristic headphones in a suspended, disassembled state. The background is a deep tech blue, and the internal components have a semi-transparent holographic technological texture, emphasizing the combination of internal precision craftsmanship and modern technology. High-tech commercial poster style.
Image 5: A 35mm humanistic shot of the wearing scenario, with a close-up on the model's jawline and neck, showing the perfect fit of the champagne gold headphones. Natural warm sunset light from the side-rear creates a rim light, with the edges of the hair glowing gold. The model's skin tone has a healthy and natural texture, creating a relaxed, immersive music-listening lifestyle feel. The background is a blurry home environment.
Image 6: A still life photograph paying homage to architectural light and shadow. The headphones are placed on a minimalist gray concrete table. Afternoon sunlight streams through blinds, casting striped hard shadows that cut across the matte cream-white body and champagne gold frame, creating a strong geometric composition of light and dark. This highlights the three-dimensional shape of the body and the contrast of materials. A clash of cool and warm color tones, minimalist composition.
Image 7: A top-down flat-lay composition showing the color options. Three headphones from the series in different color schemes—silver-white, black-gold, and blue-copper—are arranged side by side. The background is a highly textured gray wool felt cloth. Soft top lighting emphasizes the diversity of the CMF design and the delicate touch of the materials. The image is clean and orderly, in a design magazine style.
Image 8: A brand lifestyle family portrait still life photograph. The retro-futuristic headphones are placed next to their matching exquisite leather case. On the table are a vinyl record player, a spinning vinyl record, and a cup of steaming coffee. The background is rendered with warm ambient lighting, dominated by a deep walnut wood tone, conveying a brand philosophy that combines a slow-paced lifestyle with high-fidelity sound quality. Cinematic narrative lighting.

Ejemplo de código: Codificación Base64 para una imagen

import os
import base64
import mimetypes

# The format is data:{mime_type};base64,{base64_data}
def encode_file(file_path):
    mime_type, _ = mimetypes.guess_type(file_path)
    with open(file_path, "rb") as image_file:
        encoded_string = base64.b64encode(image_file.read()).decode('utf-8')
    return f"data:{mime_type};base64,{encoded_string}"

# Call the encoding function. Replace "/path/to/your/image.png" with the path to your local image file, otherwise the code will not run.
image = encode_file("/path/to/your/image.png")

Método 3: Ruta de archivo local (solo SDK)

  • Python SDK: Admite tanto rutas absolutas como relativas. Las reglas de ruta de archivo son las siguientes:

    System

    Ruta del archivo de entrada

    Ejemplo (ruta absoluta)

    Ejemplo (ruta relativa)

    Linux o macOS

    file://{ruta absoluta o relativa del archivo}

    file:///home/images/test.png

    file://./images/test.png

    Windows

    file://D:/images/test.png

    file://./images/test.png

  • Java SDK: Admite solo la ruta absoluta. Las reglas de ruta de archivo son las siguientes:

    System

    Ruta del archivo de entrada

    Ejemplo (ruta absoluta)

    Linux o macOS

    file://{ruta absoluta del archivo}

    file:///home/images/test.png

    Windows

    file:///{ruta absoluta del archivo}

    file:///D:/images/test.png

  • Utilice para pruebas rápidas en desarrollo local.

Método 1: Especificar la resolución de la imagen de salida (recomendado)

En modo de edición (con al menos una imagen pasada), los niveles opcionales de resolución de salida son: 1K, 2K (predeterminado).

  • 1K: Los píxeles totales de salida son cercanos a 1024*1024, con la relación de aspecto coincidente con la última imagen de entrada.
  • 2K: Los píxeles totales de salida son cercanos a 2048*2048, con la relación de aspecto coincidente con la última imagen de entrada.
Método 2: Especificar los valores de píxeles de ancho y alto de la imagen generada
  • El total de píxeles está entre 768768 y 20482048, con un rango de relación de aspecto de [1:8, 8:1].

Solo wan2.7-image-pro en escenarios de texto a imagen admite resolución 4K.

Método 1: Referenciar la relación de aspecto de la imagen de entrada (recomendado)

En modo de edición (enable_interleave=false), los niveles opcionales de resolución de salida son: 1K (predeterminado), 2K.

  • 1K: Los píxeles totales de salida son cercanos a 1280*1280, con la relación de aspecto coincidente con la última imagen de entrada.
  • 2K: Los píxeles totales de salida son cercanos a 2048*2048, con la relación de aspecto coincidente con la última imagen de entrada.
Método 2: Especificar los valores de píxeles de ancho y alto de la imagen generada
  • El total de píxeles está entre 768768 y 20482048, con un rango de relación de aspecto de [1:4, 4:1].

Los valores reales de píxeles de la imagen de salida serán el múltiplo de 16 más cercano al valor especificado.

Solo admite especificar los valores de píxeles de ancho y alto de la imagen generada
  • El total de píxeles está entre 768768 y 12801280, con un rango de relación de aspecto de [1:4, 4:1].
  • Si no se especifica size, el sistema generará de forma predeterminada una imagen con un recuento total de píxeles de 1280*1280, con la relación de aspecto coincidente con la última imagen de entrada.

4. Edición precisa interactiva

Utilice parameters.bbox_list para seleccionar regiones específicas para editar. Solo admitido por wan2.7-image-pro y wan2.7-image.

  • Longitud de la lista: Debe coincidir con el número de imágenes de entrada. Utilice una lista vacía [] para las imágenes que no requieren edición.
  • Formato de coordenadas: [x1, y1, x2, y2] (x superior izquierda, y superior izquierda, x inferior derecha, y inferior derecha). Las coordenadas son valores absolutos de píxeles con origen (0, 0) en la esquina superior izquierda, eje x hacia la derecha, eje y hacia abajo.
  • Límite de cantidad: Un máximo de 2 cuadros delimitadores por imagen.

Ejemplo: 3 imágenes de entrada donde la imagen 1 tiene dos cuadros delimitadores y la imagen 2 tiene none

[
  [[0, 0, 12, 12], [25, 25, 100, 100]],  # Image 1 (2 boxes)
  [],                                    # Image 2 (no box)
  [[10, 10, 50, 50]]                    # Image 3 (1 box)
]

Cómo determinar las coordenadas de la región de edición

Método 1: Dibujar cuadros delimitadores con OpenCV

Dibuje cuadros delimitadores arrastrando el ratón sobre la imagen para una selección precisa e intuitiva:

# Install dependencies: pip install opencv-python
import cv2
import urllib.request

# Download a sample image (replace with your own image URL or local path)
image_url = "https://img.alicdn.com/imgextra/i3/O1CN01SfG4J41UYn9WNt4X1_!!6000000002530-49-tps-1696-960.webp"
urllib.request.urlretrieve(image_url, "example.webp")

# Read the image and open an interactive window
img = cv2.imread("example.webp")
# Drag the mouse in the pop-up window to draw a box. Press Enter to confirm, press Esc to cancel
x, y, w, h = cv2.selectROI("Draw bounding box (Enter=confirm, Esc=cancel)", img)
cv2.destroyAllWindows()

# Convert the (x, y, w, h) returned by OpenCV to the [x1, y1, x2, y2] format required by bbox_list
# Coordinate system: origin at the top-left corner, x-axis points right, y-axis points down, unit is pixels
bbox = [x, y, x + w, y + h]
print(f"Bounding box coordinates: {bbox}")  # Pass these coordinates to parameters.bbox_list
Método 2: Modelo de comprensión visual

Utilice qwen3.6-plus para identificar automáticamente las coordenadas de la región objetivo describiendo el objetivo en lenguaje natural:

# Install dependencies: pip install dashscope pillow
import os
import json
from dashscope import MultiModalConversation
import dashscope
from PIL import Image
import urllib.request

# The following URL is for the Singapore region. Replace WorkspaceId with your actual workspace ID. URLs differ by region.
dashscope.base_http_api_url = "https://{WorkspaceId}.ap-southeast-1.maas.aliyuncs.com/api/v1"

def get_bbox_list(image, prompt):
    """
    Identify target regions in an image using qwen3.6-plus and return absolute pixel coordinates.

    Args:
        image: Image URL or local path (local path format: "file:///absolute/path.png")
        prompt: Natural language description, e.g., "coffee cup", "all fruits on the plate", "the fruit in the center of the plate"

    Returns:
        [[x1, y1, x2, y2], ...] Absolute pixel coordinates that can be passed directly to bbox_list
    """
    # Concatenate user description with return format instructions
    full_prompt = (
        prompt + "\n"
        "Based on the description above, return the coordinates of the corresponding region.\n"
        "Return a maximum of 2 regions, prioritizing the most matching target.\n"
        "Strictly follow the JSON 2D list format: [[x1, y1, x2, y2], ...]\n"
        "Each set of coordinates: [top-left x, top-left y, bottom-right x, bottom-right y]\n"
        "Use absolute pixel coordinates of the original image, with (0,0) at the top-left corner, x-axis pointing right, y-axis pointing down.\n"
        "If there is only one region, you must still use a 2D list: [[x1, y1, x2, y2]]\n"
        "Only return the JSON list, do not return any other content."
    )

    messages = [
        {'role': 'user',
         'content': [
             {'image': image},
             {'text': full_prompt}
         ]}
    ]

    response = MultiModalConversation.call(
        api_key=os.getenv('DASHSCOPE_API_KEY'),
        model='qwen3.6-plus',
        messages=messages,
    )

    text = response.output.choices[0].message.content[0]["text"]
    text = text.replace("```json", "").replace("```", "").strip()
    coords = json.loads(text)

    # Handle the case where the model returns a 1D list [x1,y1,x2,y2]
    if coords and not isinstance(coords[0], list):
        coords = [coords]

    # Get image dimensions for coordinate conversion
    if image.startswith("file://"):
        local_path = image[len("file://"):]
        img = Image.open(local_path)
    else:
        tmp_path = "temp_bbox_image"
        urllib.request.urlretrieve(image, tmp_path)
        img = Image.open(tmp_path)
    width, height = img.size

    # Convert model's normalized coordinates [0, 999] to absolute pixel coordinates
    bbox_list = []
    for box in coords:
        bbox_list.append([
            int(box[0] / 1000 * width),
            int(box[1] / 1000 * height),
            int(box[2] / 1000 * width),
            int(box[3] / 1000 * height)
        ])

    return bbox_list

# === Usage examples ===
