| eric@103 | 10 | * pages containing multiple images |
| eric@105 | 11 | * spec language needs major changes |
| eric@105 | 12 | * split process_page into multiple parts: |
| eric@105 | 13 | * open page |
| eric@105 | 14 | * add image |
| eric@105 | 15 | * close page |
| eric@103 | 16 | |

| eric@39 | 25 | * check page size, if off by too much, generate warning message and |
| eric@39 | 26 | use actual scan size |
| eric@39 | 27 | * multiple page sizes, pick the right one? |
| eric@37 | 28 | |
| eric@39 | 29 | * range checking |
| eric@39 | 30 | * rotation (0, 90, 180, or 270) |
| eric@39 | 31 | * page number style (D, r, R, a, A) |

| eric@37 | 38 | |
| eric@39 | 39 | * generate text, line art - option to embed fonts |
| eric@37 | 40 | |

| eric@65 | 52 | |
| eric@65 | 53 | bitblt routines: |
| eric@65 | 54 | |
| eric@103 | 55 | * optimize G4 fax encoding |
| eric@93 | 56 | |
| eric@65 | 57 | * finish optimized bitblt code |
| eric@65 | 58 | |
| eric@103 | 59 | * optimize inner loops in flip_h and flip_v with Duff's Device |
| eric@93 | 60 | |
| eric@93 | 61 | * check for endian problems |

| eric@65 | 68 | |
| eric@65 | 69 | PDF routines: |
| eric@65 | 70 | |
| eric@65 | 71 | [Page numbers refer to _Portable Document Format Reference Manual_ by |
| eric@65 | 72 | Adobe Systems Incorporated, Addison-Wesley, 1993.] |
| eric@65 | 73 | |
| eric@65 | 74 | * proper output of real numbers - variable precision, no exponent |
| eric@65 | 75 | |
| eric@93 | 76 | * bookmarks (outline) should allow alternate destination specs, currently |
| eric@93 | 77 | only /Fit is supported |
| eric@65 | 78 | |
| eric@65 | 79 | * balance pages tree - currently a degenerate single-level tree, but the |
| eric@65 | 80 | PDF spec recommends max. of 6 children per parent |
| eric@65 | 81 | |
| eric@65 | 82 | * thumbnails |
| eric@65 | 83 | |
| eric@65 | 84 | * PDF Page rotate attribute (p. 53)? |
| eric@65 | 85 | |
| eric@65 | 86 | * memory management - need to reference count all structures and free |
| eric@65 | 87 | them as appropriate - not necessary for t2p program |
| eric@65 | 88 | |
| eric@65 | 89 | * when an object is written to the file, set a flag to indicate that |
| eric@65 | 90 | it is now immutable |
| eric@65 | 91 | |
| eric@93 | 92 | * name trees, number trees - when finalize is called, set immutable flag |
| eric@93 | 93 | and allow no further changes |
| eric@93 | 94 | |
| eric@65 | 95 | * buffered streams (vs. current callback mechanism for unbuffered streams) |
| eric@65 | 96 | |
| eric@65 | 97 | * add support for streams with multiple filters |
| eric@103 | 98 | |
| eric@103 | 99 | * linearize ("optimize") |
