search_image_signatures finds embedded image signatures — logos, stamp images, picture overlays — and returns each with its page, position, size, and content as a base64-encoded PNG ready to display. Example prompt: “Show me the stamp images on this document”.
Tool description (as the AI agent sees it):
Searches a document for embedded image signatures (logo, stamp image, picture overlays) and returns each image’s page, position, size, and content as a base64-encoded PNG ready for display. Supports PDF, DOCX, XLSX, PPTX, and 30+ more document formats. Do NOT pre-check whether the file exists — pass the filename the user provided directly. Returns a JSON object with found (count) and signatures (array with index, page, position, dimensions, sizeBytes, and imageBase64). On failure, the response text starts with ‘Image signature search failed for’ followed by the underlying exception type, message, and inner-exception chain.
A JSON array of image signatures: page, position, size, and the image as a base64 PNG.
Useful for checking that the right stamp or company seal is present, and for pulling a signature image out for an audit record. Responses can be large — images are returned whether or not you need them, so run it on the document you care about rather than across a folder.
On failure the text starts with Image signature search failed for, followed by the exception type and message.
Example prompts
“Show me the stamp images on this document.”
“Is the company seal present on the last page?”
“Extract the signature image for the audit file.”
