Properties

	Property	Type	Description
	isMacTemplateImage	boolean	A `boolean` property that determines whether the image is considered a template image. Only has an effect on macOS.

Methods

Method	Returns	Description
addRepresentation(options)	void	Adds an image representation for a specific scale factor. This can be used to explicitly add different scale factor representations to an image. This can be called on empty images.
crop(rect)	ElectronNativeImage	Returns a cropped copy of the image.
getAspectRatio(scaleFactor?)	number	Returns the image's aspect ratio. If `scaleFactor` is passed, this returns the aspect ratio corresponding to the image representation most closely matching the passed value.
getBitmap(options?)	Buffer	Returns a buffer that contains the image's raw bitmap pixel data. The difference between `getBitmap()` and `toBitmap()` is that `getBitmap()` does not copy the bitmap data, so the returned buffer must be used immediately in the current event loop tick; otherwise the data might be changed or destroyed.
getNativeHandle()	Buffer	Returns a buffer that stores the C pointer to the underlying native handle of the image. On macOS, a pointer to an `NSImage` instance is returned. The returned pointer is a weak pointer to the underlying native image, so the associated `nativeImage` instance must be kept around. Only available on macOS.
getScaleFactors()	number[]	Returns an array of all scale factors corresponding to representations for a given native image.
getSize(scaleFactor?)	ElectronNativeImageSize	Returns the size of the image. If `scaleFactor` is passed, this returns the size corresponding to the image representation most closely matching the passed value.
isEmpty()	boolean	Returns whether the image is empty.
isTemplateImage()	boolean	Returns whether the image is a template image.
resize(options)	ElectronNativeImage	Returns a resized copy of the image. If only the `height` or the `width` is specified then the current aspect ratio is preserved in the resized image.
setTemplateImage(option)	void	Marks the image as a template image.
toBitmap(options?)	Buffer	Returns a buffer that contains a copy of the image's raw bitmap pixel data.
toDataURL(options?)	string	Returns the data URL of the image.
toJPEG(quality)	Buffer	Returns a buffer that contains the image's `JPEG` encoded data.
toPNG(options?)	Buffer	Returns a buffer that contains the image's `PNG` encoded data.
