Class TGAImage


  • public class TGAImage
    extends Object
    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

        Returns the width of the image.
      • getHeight

        public int getHeight()
        Returns the height of the image.
      • getGLFormat

        public int getGLFormat()
        Returns the OpenGL format for this texture; e.g. GL.GL_BGR or GL.GL_BGRA.
      • getBytesPerPixel

        public int getBytesPerPixel()
        Returns the bytes per pixel
      • getData

        public ByteBuffer getData()
        Returns the raw data for this texture in the correct (bottom-to-top) order for calls to glTexImage2D.
      • write

        public void write​(String filename)
                   throws IOException
        Writes the image in Targa format to the specified file name.
        Throws:
        IOException
      • write

        public void write​(File file)
                   throws IOException
        Writes the image in Targa format to the specified file.
        Throws:
        IOException
      • 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.
