Functions

func GetImageInfo

func GetImageInfo(inputFilePath string) (int, int, error)

GetImageInfo 获取图片的宽高信息

func LoadImage

func LoadImage(inputImagePath string) (img image.Image, err error)

LoadImage 从文件中解码出image

func ProcessImage

func ProcessImage(inputImagePath, outputImagePath string, processConfig ImageProcessor) error

ProcessImage 图片裁剪

func ResizeImage

func ResizeImage(inputImagePath, outputImagePath string, width, height uint) error
