| 425 | 29 So, what is this? |
| 30 ================= | |
| 31 Basically .. a bunch of more and/or less random stuff. dmlib in | |
| 32 itself is a library with various things useful in demo programming. | |
| 33 There is a resource management subsystem, functions for loading | |
| 34 PNG and JPEG images. Software blitted and scaled sprites, etc. | |
| 35 Bitmap font routines. A XM module replayer. | |
| 36 | |
| 37 And a work-in-progress timeline-supporting demo framework, with | |
| 38 a Qt based GUI editor. | |
| 39 | |
| 40 And graphics converter and displayer for various restricted formats, | |
| 41 such as C64/VIC-20 characters, bitmaps, sprites, etc. | |
| 42 | |
| 43 .. So, yeah. There are many things in here. It's a junkyard of various | |
| 882 | 44 demo- or such development related pieces of code and utilities. Many |
| 45 parts can be disabled during compile-time from config.mak | |
| 425 | 46 |
| 47 Most modules can be enabled or disabled, per project basis via | |
| 48 compile-time configuration in config.mak. | |

| 425 | 54 Requirements |

| 56 The compilation and usage of these utilities requires following | |

66 - libSDL 2.0 |
| 882 | 67 - zlib |
| 425 | 68 - libPNG 1.2 and development headers (more optional, |
| 69 only required for PNG write and read support by some | |
| 70 utilities.) | |
| 1558 | 71 - SDL2_ttf for libSDL2 (optional, required for some things) |
| 425 | 72 - Tremor (integer-based Ogg Vorbis decoder) + libogg |
| 73 | |
| 862 | 74 And the demo editor framework requires (but it is not yet |
| 75 usable anyway, so you may as well skip these): | |
| 425 | 76 |
| 1558 | 77 - Qt 5.x framework libraries |
| 425 | 78 |
| 79 | |
| 80 For Linux -> Win32/64 cross-compilation I have used the standard | |
| 81 MinGW packages from Debian Testing (wheezy): | |
| 82 | |
| 83 gcc-mingw-w64 mingw-w64-i686-dev mingw-w64-x86-64-dev | |
| 84 | |
| 1558 | 85 with the additions of cross-compiled libSDL, zlib, Tremor, libogg |
| 86 and libPNG. The SDL-related stuff for MinGW can be found from | |
| 87 libSDL's website, though some things you may need to cross-compile | |
| 88 yourself. YMMV. | |
| 425 | 89 |
| 90 Please don't ask me for help to get cross-compilation working. | |

| 425 | 96 How to build |
| 97 ============ | |
| 98 1) $ cp config.mak.in config.mak | |
| 99 | |
| 100 2) Edit config.mak to enable/disable desired options. | |
| 101 Make sure you have the required depencies. | |
| 102 | |
| 103 3) $ gmake | |
| 104 or, if cross-compiling to Win32 via MinGW | |
| 105 $ gmake -f Makefile.w32 | |
| 106 | |
| 107 4) If it works -> Happy fun times \:D\ | |

| 425 | 113 Included utilities |
| 114 ================== | |
| 115 | |
| 116 xm2jss | |
| 117 ------ | |
| 1936 | 118 Convert XM modules to internal JMOD format. You can optionally optimize the |
| 119 module and even strip out various parts, such as complete instruments | |
| 120 (leaving only pattern data), sample data, sample instruments, etc. | |

123 dumpmod |
| 425 | 124 ------- |
| 1936 | 125 Simple XM/JMOD viewer. Dumps selected parts into stdout as text format data. |
| 425 | 126 |
| 127 | |
| 128 ppl | |
| 129 --- | |
| 130 A simple XM/JMOD player with SDL-based UI. | |
| 131 | |
| 1936 | 132 |
| 425 | 133 testpl |
| 134 ------ | |
| 135 Even simpler player, with no UI at all. Uses SDL for audio. | |
| 136 | |
| 1936 | 137 |
| 425 | 138 mod2wav |
| 139 ------- | |
| 140 Render XM/JMOD modules into WAV files. | |
| 141 | |
| 142 | |
| 143 packed | |
| 144 ------ | |
| 145 Manipulate DMPACK files. Basically a bit like ZIP archive, | |
| 146 for glueing resource files into a zlib-compressed blob. | |
| 147 The dmlib resource subsystem can utilize these files. | |
| 148 | |
| 149 fontconv | |
| 150 -------- | |
| 151 Convert bitmap fonts. | |
| 152 | |
| 153 | |
| 154 objlink | |
| 155 ------- | |
| 156 Simple, but versatile commandline utility for combining binary | |
| 157 files into one file. Understands 2-byte loading address PRG | |
| 158 style files, and raw data. "Loading addresses" can be specified | |
| 159 and overridden. The utility also checks for overlaps, etc. | |
| 160 | |
| 1936 | 161 |
| 425 | 162 data2inc |
| 163 -------- | |
| 164 Simple data file to C/ASM source converter. | |
| 165 | |
| 1936 | 166 |

171 (including PNG, PCX, PPM, IFF ILBM and RAW/ARAW files). |
| 425 | 172 |
| 1794 | 173 Input can also be interpreted as bitmap, sprite or character data, |
| 425 | 174 in multicolor or single color. Colors can be mapped as desired. |
| 175 Image file output can be either single image (with chars/sprites | |
| 176 placed vertically if input is char/sprite data), or in separate | |
| 177 files. | |
| 178 | |

| 425 | 190 Examples |
| 191 ======== | |
| 192 | |
| 193 data2inc | |
| 194 -------- | |
| 195 To convert a data file to a C structure using 'uint8_t' as type: | |
| 196 | |
| 197 $ data2inc -C -n variable_name -t uint8_t input.bin output.h | |
| 198 | |
| 199 | |
| 200 objlink | |
| 201 ------- | |
| 202 $ objlink -o intro.tmp -pppp intro.o gfx/dkdlogo2.drp:0x3800 \ | |
| 203 muzak.prg gfx/chars_4.fnt:0x6800 | |
| 204 | |
| 205 - "-o intro.tmp" sets output file | |
| 206 - As you can see, short options can be combined, like "-pppp". | |
| 207 However, the next parameters must be the corresponding option | |
| 208 arguments, in correct order, if any. | |
| 209 - It is possible to specify a overriding loading address via | |
| 210 ":<addr>" syntax. See the help for more information. | |
