getCallInterface

default org.lwjgl.system.libffi.FFICIF getCallInterface()

Specified by:

getCallInterface in interface org.lwjgl.system.CallbackI

callback

default void callback(long ret,
 long args)

Specified by:

callback in interface org.lwjgl.system.CallbackI

invoke

int invoke(int miplevel,
 int face,
 int width,
 int height,
 int depth,
 long faceLodSize,
 long pixels,
 long userdata)

Signature of function called by the ktxTexture_Iterate* functions to receive image data.

The function parameters are used to pass values which change for each image. Obtain values which are uniform across all images from the ktxTexture object.

Parameters:

miplevel - MIP level from 0 to the max level which is dependent on the texture size

face - usually 0; for cube maps, one of the 6 cube faces in the order +X, -X, +Y, -Y, +Z, -Z, 0 to 5

width - width of the image

height - height of the image or, for 1D textures textures, 1

depth - depth of the image or, for 1D & 2D textures, 1

faceLodSize - number of bytes of data pointed at by pixels

pixels - pointer to the image data

userdata - pointer for the application to pass data to and from the callback function
