Smart Image Outpainting API AI Prompts & Use Cases
After connecting this MCP tool to your AI assistant, you can ask the questions below. Replace bracketed placeholders with your own inputs and use the supported values in Arguments.
New to Nexscope MCP? Follow the connection guide, then use the prompts below. The Integration and Parameters & Response tabs contain the connection steps, call example, and technical reference.
1. Expand An Image For A Layout
Prompt: Expand [image] to [width] by [height] pixels, extending the scene according to [brief]. Keep the original subject intact.
2. Create Several Alternatives
Prompt: Expand [image] to [width] by [height] pixels, extending the scene according to [brief]. Keep the original subject intact. Create [number of outputs within this tool’s supported limit] for review, keeping the same source material and brief.
3. Prepare Two Canvas Formats From One Product Image
Prompt: Expand [source image] into [width A by height A] and [width B by height B] for two planned placements. Use the same [background brief] and two separate requests for one image each. Wait for completed results and review subject visibility in each format; do not claim a single multi-size request, automatic cropping control or platform approval.
What You Need to Provide
Provide assets you may use and that meet this tool’s documented file, dimension and count limits.
A pending task is not a completed image, video or text result. Retrieve the existing task rather than submitting a duplicate.
Request one to four outputs; the default is one.
