Types ¶
type Config ¶
type Config struct {
Width, Height int
Format string
Modified bool // true if Decode actually rotated or flipped the image.
}
Config is like the standard library's image.Config as used by DecodeConfig.
type DecodeOpts ¶
type DecodeOpts struct {
// Rotate specifies how to rotate the image.
// If nil, the image is rotated automatically based on EXIF metadata.
// If an int, Rotate is the number of degrees to rotate
// counter clockwise and must be one of 0, 90, -90, 180, or
// -180.
Rotate interface{}
// Flip specifies how to flip the image.
// If nil, the image is flipped automatically based on EXIF metadata.
// Otherwise, Flip is a FlipDirection bitfield indicating how to flip.
Flip interface{}
// MaxWidgth and MaxHeight optionally specify bounds on the
// final image's size.
MaxWidth, MaxHeight int
}
type FlipDirection ¶
type FlipDirection int
The FlipDirection type is used by the Flip option in DecodeOpts to indicate in which direction to flip an image.
const ( FlipVertical FlipDirection = 1 << iota FlipHorizontal )
FlipVertical and FlipHorizontal are two possible FlipDirections values to indicate in which direction an image will be flipped.
