Class TGAImage
java.lang.Object
com.jogamp.opengl.util.texture.spi.TGAImage
Targa image reader and writer adapted from sources of the Jimi image I/O class library.
Image decoder for image data stored in TGA file format. Currently only the original TGA file format is supported. This is because the new TGA format has data at the end of the file, getting to the end of a file in an InputStream orient environment presents several difficulties which are avoided at the moment.
This is a simple decoder and is only setup to load a single image from the input stream

This class reads in all of the TGA image header in addition it also reads in the imageID field as it is convenient to handle that here. -

createFromData
public static TGAImage createFromData(int width, int height, boolean hasAlpha, boolean topToBottom, ByteBuffer data) Creates a TGAImage from data supplied by the end user. Shares data with the passed ByteBuffer. Assumes the data is already in the correct byte order for writing to disk, i.e., BGR or BGRA.
