Constants

const (
	// ImageFormatUndefined is a reserved ImageFormat for cases when it's undefined
	// So if anybody will have an ImageFormat with zero-value (not defined, yet) it won't receive
	// a mis-leading value like ImageFormatJPEG.
	ImageFormatUndefined = imageprocessorcommon.ImageFormatUndefined

	// ImageFormatJPEG is an ImageFormat for JPEGs
	ImageFormatJPEG = imageprocessorcommon.ImageFormatJPEG

	// ImageFormatOther is an ImageFormat for all image formats not listed here in this enumeration
	ImageFormatOther = imageprocessorcommon.ImageFormatOther
)

Variables

var (
	// ErrInvalidSize is returned when an invalid size is passed in arguments
	// to a function
	ErrInvalidSize = imageprocessorcommon.ErrInvalidSize
)

Types

type ImageFormat

type ImageFormat = imageprocessorcommon.ImageFormat

ImageFormat is an enumeration data-type for image formats

type ImageProcessor

type ImageProcessor = imageprocessorcommon.ImageProcessor

ImageProcessor is a tool to manipulate images

func NewImageProcessor

func NewImageProcessor() ImageProcessor

NewImageProcessor creates an instance of `ImageProcessor` (image manipulation tool).

Currently is uses a GraphicsMagick-based implementation (`github.com/xaionaro-go/picapi/imageprocessor/graphicsmagick`).
