Functions ¶
func ExtractTimestampFromPath ¶
ExtractTimestampFromPath extracts the timestamp from a timestamped path Returns zero time if the path doesn't have a valid timestamp
func GenerateTimestampedPath ¶
GenerateTimestampedPath generates a timestamped relative path for an image Format: YYYYMMDD_HHMMSS_microseconds_originalfilename.ext Example: 20251015_143052_123456_yorkshire-terrier.jpg
func GenerateTimestampedPathWithPrefix ¶
GenerateTimestampedPathWithPrefix generates a timestamped path with custom prefix
func GetOriginalFilename ¶
GetOriginalFilename extracts the original filename from a timestamped path
func IsTimestampedPath ¶
IsTimestampedPath checks if a path follows the timestamped format
