    getImgULX Method (BitstreamReaderAgent)
    In This Topic
    Returns the horizontal coordinate of the image origin, the top-left corner, in the canvas system, on the reference grid at the specified resolution level.

    Note: Image resolution level indexes may differ from tile-component resolution index. They are indeed indexed starting from the lowest number of decomposition levels of each component of each tile.

    Example: For an image (1 tile) with 2 components (component 0 having 2 decomposition levels and component 1 having 3 decomposition levels), the first (tile-) component has 3 resolution levels and the second one has 4 resolution levels, whereas the image has only 3 resolution levels available.
