    getCompImgWidth Method (FileBitstreamReaderAgent)
    In This Topic
    Returns the width in pixels of the specified component in the overall image, for the given (component) resolution level.

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

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