| eric@153 | 8 | tumble: |
| eric@65 | 9 | |
| eric@144 | 10 | * input handlers shouldn't use globals, use pointer to private structure |
| eric@144 | 11 | instead. |

| eric@39 | 31 | use actual scan size |
| eric@39 | 32 | * multiple page sizes, pick the right one? |
| eric@37 | 33 | |
| eric@39 | 34 | * range checking |
| eric@39 | 35 | * rotation (0, 90, 180, or 270) |

| eric@37 | 37 | |
| eric@39 | 38 | * watermarking - in image? |
| eric@37 | 39 | |
| eric@65 | 40 | * flip, transpose |
| eric@37 | 41 | |
| eric@153 | 42 | * support color & grayscale TIFF images |
| eric@153 | 43 | * pass JPEG through unchanged, others must be encoded |
| eric@153 | 44 | |
| eric@103 | 45 | * support PNG, BMP, and other input file formats |
| eric@37 | 46 | |
| eric@39 | 47 | * generate text, line art - option to embed fonts |
| eric@37 | 48 | |
| eric@153 | 49 | * bilevel thresholding of color and grayscale input |
| eric@52 | 50 | |
| eric@52 | 51 | * automatic separation using timify code from Tim Shoppa? |
| eric@52 | 52 | |
| eric@52 | 53 | * automatic image detection using DCT or FFT |
| eric@52 | 54 | |
| eric@52 | 55 | * downsampling |
| eric@65 | 56 | |
| eric@65 | 57 | ----------------------------------------------------------------------------- |
| eric@65 | 58 | |
| eric@65 | 59 | bitblt routines: |
| eric@65 | 60 | |
| eric@65 | 61 | * finish optimized bitblt code |
| eric@65 | 62 | |
| eric@103 | 63 | * optimize inner loops in flip_h and flip_v with Duff's Device |
| eric@93 | 64 | |
| eric@93 | 65 | * check for endian problems |
| eric@153 | 66 | * reading TIFF (don't define TIFF_REVERSE_BITS on some hosts) |
| eric@105 | 67 | * rle table |
| eric@105 | 68 | * g4_get_pixel() |
| eric@105 | 69 | * g4_find_pixel() |
| eric@93 | 70 | |
| eric@111 | 71 | * g4_find_pixel should use native instructions where available |
| eric@111 | 72 | * 386: BSF bit scan forward |
| eric@111 | 73 | * PowerPC: CLTLZ, CNTLZW count leasing zeros (CNTLZD 64-bit) |

| eric@65 | 79 | PDF routines: |
| eric@65 | 80 | |
| eric@65 | 81 | [Page numbers refer to _Portable Document Format Reference Manual_ by |
| eric@65 | 82 | Adobe Systems Incorporated, Addison-Wesley, 1993.] |
| eric@65 | 83 | |
| eric@155 | 84 | * Flate compression - including predictors |
| eric@155 | 85 | |
| eric@120 | 86 | * ModDate and CreationDate keys in Info dict |
| eric@120 | 87 | |
| eric@120 | 88 | * ID key in trailer dict |
| eric@120 | 89 | |
| eric@65 | 90 | * proper output of real numbers - variable precision, no exponent |
| eric@65 | 91 | |
| eric@93 | 92 | * bookmarks (outline) should allow alternate destination specs, currently |
| eric@93 | 93 | only /Fit is supported |
| eric@65 | 94 | |
| eric@65 | 95 | * balance pages tree - currently a degenerate single-level tree, but the |
| eric@65 | 96 | PDF spec recommends max. of 6 children per parent |
| eric@65 | 97 | |
| eric@65 | 98 | * thumbnails |
| eric@65 | 99 | |
| eric@65 | 100 | * PDF Page rotate attribute (p. 53)? |
| eric@65 | 101 | |
| eric@65 | 102 | * memory management - need to reference count all structures and free |
| eric@65 | 103 | them as appropriate - not necessary for t2p program |
| eric@65 | 104 | |
| eric@65 | 105 | * when an object is written to the file, set a flag to indicate that |
| eric@65 | 106 | it is now immutable |
| eric@65 | 107 | |
| eric@93 | 108 | * name trees, number trees - when finalize is called, set immutable flag |
| eric@93 | 109 | and allow no further changes |
| eric@93 | 110 | |
| eric@65 | 111 | * buffered streams (vs. current callback mechanism for unbuffered streams) |
| eric@65 | 112 | |
| eric@65 | 113 | * add support for streams with multiple filters |
| eric@103 | 114 | |
| eric@103 | 115 | * linearize ("optimize") |
