Image

A wrapper trait for images that might be stored in various ways. Be warned that using this wrapper probably introduces some inefficiency. Also, images are currently treated as immutable, which may introduce a serious performance problem; in the future we may need to add a set() method.

If you have a choice and performance matters to you, use ChannelMajorArrayVectorizedImage, as it is likely to be the most efficient implementation.

Abstract Value Members

abstract def get(x: Int, y: Int, channelIdx: Int): Double

Get the pixel value at (x, y, channelIdx).
Get the pixel value at (x, y, channelIdx). Channels are indexed as follows:
- If the image is RGB, 0 => blue, 1 => green, 2 => red.
- If the image is RGB+alpha, 0 => blue, 1=> green, 2 => red, and 3 => alpha.
- Other channel schemes are unsupported; the only reason this matters is that input converters (e.g. from BufferedImage to Image) need to handle channels consistently.
abstract val metadata: ImageMetadata
abstract def put(x: Int, y: Int, channelIdx: Int, newVal: Double): Unit

Put a pixel value at (x, y, channelIdx).

Returns a flat version of the image, represented as a single array.
Returns a flat version of the image, represented as a single array. It is indexed as follows: The pixel value for (x, y, channelIdx) is at channelIdx + x*numChannels + y*numChannels*xDim.
This implementation works for arbitrary image formats but it is inefficient.
