Method Detail

getImageAsByteBuffer

public static ByteBuffer getImageAsByteBuffer(Image image)

getImagePixels

public static int[] getImagePixels(Image image)

getImageAsByteBuffer

public static ByteBuffer getImageAsByteBuffer(Image image,
                                              int width,
                                              int height)

Create a ByteBuffer containing a RGBA pixels out of an Image made of ARGB pixels. The buffer can later be drawn by GL2.glDrawPixels(imgW, imgH, GL2.GL_RGBA, GL2.GL_UNSIGNED_BYTE, byteBuffer);

Parameters:

image -

width -

height -

Returns:

getImagePixels

public static int[] getImagePixels(Image image,
                                   int width,
                                   int height)

Return the image pixels in default Java int ARGB format.

Parameters:

image -

width -

height -

Returns:

convertARGBtoRGBA

public static ByteBuffer convertARGBtoRGBA(int[] pixels,
                                           int width,
                                           int height,
                                           boolean flipVertically)

Convert ARGB pixels to a ByteBuffer containing RGBA pixels. Can be drawn in ORTHO mode using: GL2.glDrawPixels(imgW, imgH, GL2.GL_RGBA, GL2.GL_UNSIGNED_BYTE, byteBuffer); If flipVertically is true, pixels will be flipped vertically for OpenGL coord system.

Parameters:

imgFilename -

Returns:

ByteBuffer

convertARGBtoRGBA

public static byte[] convertARGBtoRGBA(int[] pixels)

Convert pixels from java default ARGB int format to byte array in RGBA format.

Parameters:

pixels -

Returns:

getRGBABytes

public static byte[] getRGBABytes(int[] pixels)

flipPixels

public static int[] flipPixels(int[] imgPixels,
                               int imgw,
                               int imgh)

Flip an array of pixels vertically

Parameters:

imgPixels -

imgw -

imgh -

Returns:

int[]

allocBytes

public static ByteBuffer allocBytes(byte[] byteArray)

Allocates a ByteBuffer to hold the given array of bytes.

Parameters:

byteArray -

Returns:

ByteBuffer containing the contents of the byte array

getByteBuffer

public static ByteBuffer getByteBuffer(Image img,
                                       int width,
                                       int height)

Return a ByteBuffer out of the image. Not used in the framework. Look rather for getImageAsByteBuffer(Image, int, int) that has same signature and more used implementation.

Parameters:

img -

width -

height -

Returns:
