        // In the original implementation, a general-case bit reader called
        // getSamplesAsBytes is used to retrieve the samples (raw data values)
        // for each pixel in the strip. These samples are then passed into a
        // photogrammetric interpreter that converts them to ARGB pixel values
        // and stores them in the image. Because the bit-reader must handle
        // a large number of formats, it involves several conditional
        // branches that must be executed each time a pixel is read.
        // Depending on the size of an image, the same evaluations must be
        // executed redundantly thousands and perhaps millions of times
        // in order to process the complete collection of pixels.
        // This code attempts to remove that redundancy by
        // evaluating the format up-front and bypassing the general-format
        // code for two commonly used data formats: the 8 bits-per-pixel
        // and 24 bits-per-pixel cases. For these formats, the
        // special case code achieves substantial reductions in image-loading
        // time. In other cases, it simply falls through to the original code
        // and continues to read the data correctly as it did in previous
        // versions of this class.
        // In addition to bypassing the getBytesForSample() method,
        // the 24-bit case also implements a special block for RGB
        // formatted images. To get a sense of the contributions of each
        // optimization (removing getSamplesAsBytes and removing the
        // photometric interpreter), consider the following results from tests
        // conducted with large TIFF images using the 24-bit RGB format
        // bypass getSamplesAsBytes: 67.5 % reduction
        // bypass both optimizations: 77.2 % reduction
        //
        //
        // Future Changes
        // Both of the 8-bit and 24-bit blocks make the assumption that a strip
        // always begins on x = 0 and that each strip exactly fills out the rows
        // it contains (no half rows). The original code did not make this
        // assumption, but the approach is consistent with the TIFF 6.0 spec
        // (1992),
        // and should probably be considered as an enhancement to the
        // original general-case code block that remains from the original
        // implementation. Taking this approach saves one conditional
        // operation per pixel or about 5 percent of the total run time
        // in the 8 bits/pixel case.
