Functions

func DecodeConfig

func DecodeConfig(r io.Reader) (width, height int, err error)

DecodeConfig reports image dimensions without full decode when possible.

func FormatToolResult

func FormatToolResult(relPath, mime string, width, height int, data []byte) string

FormatToolResult builds ReadMediaFile tool output with metadata and base64 PNG.

func Normalize

func Normalize(data []byte, mimeHint string) ([]byte, string, int, int, error)

Normalize decodes an image, optionally downscales, and re-encodes as PNG.

func ReadPath

func ReadPath(path string) (data []byte, mime string, width, height int, err error)

ReadPath reads an image file and returns normalized PNG bytes for vision APIs.

func SaveAttachment

func SaveAttachment(workDir, sessionSuffix string, data []byte) (absPath, relPath string, err error)

SaveAttachment writes PNG bytes under <workDir>/.agents/elph/attachments/.
