     4 No particular order.
     6 -----------------------------------------------------------------------------
     8 t2p:
    10 * pages containing multiple images
    12 * support JPEG (JFIF, EXIF)
    14 * page labels
    16 * crop
    18 * page sizes
    19     * metric
    20     * check page size, if off by too much, generate warning message and
    21       use actual scan size
    22     * multiple page sizes, pick the right one?
    24 * range checking
    25     * rotation (0, 90, 180, or 270)
    26     * page number style (D, r, R, a, A)
    28 * watermarking - in image?
    30 * flip, transpose
    32 * support PNG, BMP, and other input file formats
    34 * generate text, line art - option to embed fonts
    36 * overlay G4 images in different colors - use ImageMask and the fill color
    38 * bilevel thresholding of color and grey scale input
    40 * automatic separation using timify code from Tim Shoppa?
    42 * automatic image detection using DCT or FFT
    44 * downsampling
    46 -----------------------------------------------------------------------------
    48 bitblt routines:
    50 * optimize G4 fax encoding
    52 * finish optimized bitblt code
    54 * optimize inner loops in flip_h and flip_v with Duff's Device
    56 * check for endian problems
    58 -----------------------------------------------------------------------------
    60 PDF routines:
    62 [Page numbers refer to _Portable Document Format Reference Manual_ by
    63 Adobe Systems Incorporated, Addison-Wesley, 1993.]
    65 * proper output of real numbers - variable precision, no exponent
    67 * bookmarks (outline) should allow alternate destination specs, currently
    68   only /Fit is supported
    70 * balance pages tree - currently a degenerate single-level tree, but the
    71   PDF spec recommends max. of 6 children per parent
    73 * thumbnails
    75 * PDF Page rotate attribute (p. 53)?
    77 * memory management - need to reference count all structures and free
    78   them as appropriate - not necessary for t2p program
    80 * when an object is written to the file, set a flag to indicate that
    81   it is now immutable
    83 * name trees, number trees - when finalize is called, set immutable flag
    84   and allow no further changes
    86 * buffered streams (vs. current callback mechanism for unbuffered streams)
    88 * add support for streams with multiple filters
    90 * linearize ("optimize")
