Method Detail

createEmptyImage

public static Image createEmptyImage(Image.Format format,
                                     int width,
                                     int height,
                                     int depth)

Creates an image of the given size and depth.

Parameters:

format - the image format

width - the image width

height - the image height

depth - the image depth

Returns:

the new image instance

color

public static TexturePixel color(TexturePixel pixel,
                                 ColorRGBA lowIntensityColor,
                                 ColorRGBA highIntensityColor)

The method sets a color for the given pixel by merging the two given colors. The lowIntensityColor will be most visible when the pixel has low intensity. The highIntensityColor will be most visible when the pixel has high intensity.

Parameters:

pixel - the pixel that will have the colors altered

lowIntensityColor - the low intensity color

highIntensityColor - the high intensity color

Returns:

the altered pixel (the same instance)

merge

public static void merge(Image targetImage,
                         Image sourceImage)

This method merges two given images. The result is stored in the 'target' image.

Parameters:

targetImage - the target image

sourceImage - the source image

mix

public static void mix(Image targetImage,
                       Image sourceImage)

This method merges two given images. The result is stored in the 'target' image.

Parameters:

targetImage - the target image

sourceImage - the source image

resizeTo

public static Image resizeTo(Image source,
                             int width,
                             int height)

Resizes the image to the given width and height.

Parameters:

source - the source image (this remains untouched, the new image instance is created)

width - the target image width

height - the target image height

Returns:

the resized image

convertToNormalMapTexture

public static Image convertToNormalMapTexture(Image source,
                                              float strengthFactor)

This method converts the given texture into normal-map texture.

Parameters:

source - the source texture

strengthFactor - the normal strength factor

Returns:

normal-map texture

convertToGrayscaleTexture

public static Image convertToGrayscaleTexture(Image source)

This method converts the given texture into black and whit (grayscale) texture.

Parameters:

source - the source texture

Returns:

grayscale texture

decompress

public static Image decompress(Image image)

This method decompresses the given image. If the given image is already decompressed nothing happens and it is simply returned.

Parameters:

image - the image to decompress

Returns:

the decompressed image
