Class TGrayscaleFloatImage

Unit

CastleImages

Declaration

type TGrayscaleFloatImage = class(TCastleImage)

Description

Image with Single (floating-point number) for each pixel. Ideal for high-precision height maps. Compared to TGrayscaleImage, each pixel is a floating-point number, which means it is more precise and can also be above 1.0 value (though they are still in 0..1 range when reading from normal image formats).
