Uses Color.luminosity to calculate the logarithmic mean of the image luminosity as L_avg = 10 ^ ( sum( log10(delta + L(pixel)) ) / N ). default parameter delta is to prevent black pixels from appearing in the output image

clampImage

fun clampImage()

Applies the bright spot correction as x -> x / (1 + x)

equals

open operator override fun equals(other: Any?): Boolean

getPixel

fun getPixel(x: Int, y: Int): Color

Returns the Color of the pixel at (x, y).

hashCode

open override fun hashCode(): Int

normalizeImage

fun normalizeImage(factor: Float, luminosity: Float? = null)

Renormalizes the luminosity of the image pixels.

pixelOffset

fun pixelOffset(x: Int, y: Int): Int

Converts 2D coordinates (x, y) into a flat 1D array index.

setPixel

fun setPixel(x: Int, y: Int, newColor: Color)

Sets the pixel at (x, y) to newColor.

writeLDRImage

fun writeLDRImage(stream: OutputStream, format: String, gamma: Float = 1.0f)

Saves the current image to stream in LDR format (e.g. "png", "jpg") applying gamma correction through P_out = P_in^(1/gamma).

writePFMFile

fun writePFMFile(fileName: String, order: ByteOrder = LITTLE_ENDIAN)

Uses the writePFMImage fun to save this image to fileName in PFM format.

writePFMImage

fun writePFMImage(stream: OutputStream, order: ByteOrder)

Writes this image to stream in PFM format with order endianness.
