Function inboundImageToModels

cli/gateway_command.go:625–643

inboundImageToModels converts a hydrated gateway image attachment into the provider-agnostic models.ImageContent carried on a user turn. It returns a 0- or 1-element slice (downstream callers carry a slice): an attachment without bytes or with an unsupported media type yields none.

(im *gateway.InboundImage)

// 0- or 1-element slice (downstream callers carry a slice): an attachment
// without bytes or with an unsupported media type yields none.
func inboundImageToModels(im *gateway.InboundImage) []models.ImageContent {
	if im == nil || len(im.Data) == 0 {
		return nil
	}
	mime := im.MimeType
	if _, ok := models.NormalizeImageMediaType(mime); !ok {
		// Fall back to sniffing when the platform sent no/!supported MIME.
		if sniffed, ok2 := models.DetectImageMediaType(im.Data); ok2 {
			mime = sniffed
		} else {
			return nil
		}
	}
	return []models.ImageContent{{
		MediaType: mime,
		Data:      im.Data,
		FileName:  im.FileName,
