Functions ¶
func NewSubImage ¶
NewSubImage returns a subimage of the given source image based on the specified bounds.
func ReadFile ¶
ReadFile reads an image file (gif, jpeg or png) specified by imgPath and returns it as an image.Image.
func WriteBMP ¶
WriteBMP writes the image data to a BMP file specified by imgPath. WriteBMP creates the named file using mode 0666 (before umask), truncating it if it already exists
func WriteFile ¶
WriteFile writes the image data to a PNG file specified by imgPath. WriteFile creates the named file using mode 0666 (before umask), truncating it if it already exists.
Types ¶
type SubImager ¶
type SubImager interface {
image.Image
// SubImage returns an image representing the portion of the image visible
// through r. The returned value shares pixels with the original image.
SubImage(r image.Rectangle) image.Image
}
SubImager is an interface that extends the basic image.Image interface with the SubImage method.
func SubFallback ¶
SubFallback returns the provided image.Image as a SubImager. It provides a fallback for images missing the SubImage method.
