Deck2PDF is also capable 14 | of handling other HTML5 libraries as long as you feed it <>. 15 | 16 | This application relies on a JavaFX application, so you need at least a Java 7 installation that bundles JavaFX (which should be the case for all newer installs of Java). 17 | 18 | == Download 19 | 20 | Pre-built binaries for JDK 8 can be download from https://bintray.com/melix/generic-maven/deck2pdf/0.3.0/view#files[Bintray]. 21 | 22 | If you use Gradle (or any Maven-compatible dependency resolution engine), artifacts are available on JCenter: 23 | 24 | ```groovy 25 | repositories { 26 | jcenter() 27 | } 28 | dependencies { 29 | compile 'me.champeau.deck2pdf:deck2pdf:0.3.0' 30 | } 31 | ``` 32 | 33 | == Install from source 34 | 35 | image::https://travis-ci.org/melix/deck2pdf.png?branch=master[Build Status, link="https://travis-ci.org/melix/deck2pdf"] 36 | 37 | Alternatively, you can install deck2pdf from sources. 38 | 39 | ---- 40 | ./gradlew distZip 41 | ---- 42 | 43 | Will generate a distribution into `build/distributions/` that you can unzip wherever you want. 44 | 45 | == Changelog 46 | 47 | === 0.3.0 48 | 49 | * Change `group` from `com.github.melix` to `me.champeau.deck2pdf` 50 | * Add ability to export to PNG or JPEG 51 | * Require Java 8 52 | 53 | == Usage 54 | 55 | ---- 56 | deck2pdf --profile=deckjs 57 | ---- 58 | 59 | By default, deck2pdf assumes that you are using deck.js, but there more profiles supported: 60 | 61 | * deckjs, for http://imakewebthings.com/deck.js/[deck.js] 62 | * revealjs, for http://lab.hakim.se/reveal-js[reveal.js] 63 | * impressjs, for http://bartaz.github.io/impress.js[impress.js] 64 | * dzslides, for https://github.com/paulrouget/dzslides[DZSlides] 65 | * flowtimejs, for http://flowtime-js.marcolago.com/[Flowtime.js] 66 | * googlehtml5, for http://code.google.com/p/html5slides/[Google html5slides] 67 | * spf, for https://github.com/briancavalier/slides[Slide Presentation Framework] 68 | * remarkjs, for https://github.com/gnab/remark[remark.js] 69 | * ruban, for https://github.com/loicfrering/ruban[ruban]. Note that the ruban profile expects to find the Ruban object in the global variable `ruban`. The minimum version of Ruban is 0.3.2. 70 | 71 | For example, to convert a Deck.js slidedeck into PDF: 72 | 73 | ---- 74 | deck2pdf slides.html slides.pdf 75 | ---- 76 | 77 | Or for a reveal.js slidedeck: 78 | 79 | ---- 80 | deck2pdf --profile=revealjs slides.html slides.pdf 81 | ---- 82 | 83 | Optionally, you can specify width and height: 84 | 85 | ---- 86 | deck2pdf --width=1024 --height=768 slides.html slides.pdf 87 | ---- 88 | 89 | To export the slides as multiple images (PNG or JPG), change the file extension of the export file to .png or .jpg. 90 | 91 | ---- 92 | deck2pdf slides.html slides.png 93 | ---- 94 | 95 | You can use a number pattern in the file name (e.g., `%03d`) to have the slide numbers padded so they have a fixed length: 96 | 97 | ---- 98 | deck2pdf slides.html slides-%03d.png 99 | ---- 100 | 101 | You can also specify a quality option for JPG (default: 0.95): 102 | 103 | ---- 104 | deck2pdf --quality=75 slides.html slides.jpg 105 | ---- 106 | 107 | WARNING: The JPG export is not available when using OpenJDK. 108 | You must use the Oracle JDK instead. 109 | 110 | For a remark.js slideshow, make sure you use `window.slideshow = remark.create();` to initialize the slideshow 111 | 112 | == Profile specific options 113 | 114 | Some profiles have specific command line options that allow further configuration of the export. This section summarizes 115 | the options available for such profiles. 116 | 117 | === reveal.js 118 | 119 | [cols="1,3,1,1",options="header,footer"] 120 | |======================================================================= 121 | |Option|Behavior|Default|Example 122 | |skipFragments|If `true`, fragments will be ignored, otherwise each fragment will generate an individual slide|false|`deck2pdf --skipFragments=true revealjs.html` 123 | |======================================================================= 124 | 125 | === ruban 126 | 127 | [cols="1,3,1,1",options="header,footer"] 128 | |======================================================================= 129 | |Option|Behavior|Default|Example 130 | |skipSteps|If `true`, instead of generating one PDF page per step, generates one PDF slide per section, with the last step of each section.|false|`deck2pdf --skipSteps=true index.html` 131 | |======================================================================= 132 | 133 | 134 | [[CustomProfiles]] 135 | == Support for other HTML5 slideshows 136 | 137 | `deck2pdf` is capable of handling many HTML5 slideshows. The current distribution supports several profiles out of the 138 | box but it is easy to add yours. Depending on the complexity of the the framework, you can use either a simple 139 | properties file to describe your framework or a more complex Groovy file. Both profile types rely on the fact that 140 | you communicate with the browser with Javascript. This means that `deck2js` should be compatible with any HTML5 141 | slideshow that exposes a Javascript API. 142 | 143 | === Simple profile using properties 144 | 145 | The easiest way to define a new profile is to create a properties file. For example, here is the file that the 146 | `deck.js` export uses: 147 | 148 | ---- 149 | include::src/main/resources/deckjs.properties[] 150 | ---- 151 | 152 | The properties files consists of two entries: 153 | 154 | * `totalSlides` is a Javascript snippet which will compute the total number of slides of the deck 155 | * `nextSlide` is the Javascript code which needs to be called to jump to the next slide 156 | 157 | Properties files are very simple, so are only capable of handling decks for which the number of slides is known in 158 | advance and the command to jump from one slide to another is always the same. For more complex slide shows, you can 159 | use the http://groovy.codehaus.org[Groovy] profiles. 160 | 161 | === Advanced profiles 162 | ==== Example 163 | Advanced profiles are written using the http://groovy.codehaus.org[Groovy] scripting language. However, they are pretty 164 | simple too and they expose a simple API that should fit most situations. 165 | 166 | Here is an example of profile as it is defined for `impress.js`: 167 | 168 | [source,groovy] 169 | ---- 170 | include::src/main/resources/impressjs.groovy[] 171 | ---- 172 | 173 | The file name for a properties profile *must* end with `.properties`. 174 | 175 | ==== Groovy API 176 | 177 | The http://groovy.codehaus.org[Groovy] allows you to define more complex interactions with the slide deck. It also allows 178 | you to export slide decks for which you don't know the number of slides in advance, as long as you are capable of telling 179 | that you've reached the end of the slide deck. 180 | 181 | Calling javascript in the browser from the profile is done using the `js` function: 182 | 183 | [source,groovy] 184 | ---- 185 | js 'var slideCount = slides.length;' 186 | ---- 187 | 188 | Then the http://groovy.codehaus.org[Groovy] profile exposes some hooks that you can use: 189 | 190 | * `setup` is called once the slide deck is loaded and ready for export. It gives you a chance to perform an initial 191 | customization before exporting the slides. For example: 192 | 193 | [source,groovy] 194 | ---- 195 | setup = { 196 | // disable controls for better rendering 197 | js 'Reveal.configure({controls: false, progress: false});' 198 | } 199 | ---- 200 | 201 | * `isLastSlide` is called after a slide has been exported. If the method returns true, then export is complete. For 202 | example: 203 | 204 | [source,groovy] 205 | ---- 206 | isLastSlide = { 207 | js ''' 208 | var totalSlides = Dz.slides.length; 209 | var cSlide = Dz.idx; 210 | cSlide==totalSlides && Dz.step==Dz.slides[cSlide - 1].$$('.incremental > *').length 211 | ''' 212 | } 213 | ---- 214 | 215 | * `totalSlides` can be used to determine the total number of slides (if a slide contains a transition, each transition 216 | is counted as a slide). It is optional, as long as you define the `isLastSlide` hook. Providing it would add a counter 217 | to the log output. 218 | 219 | [source,groovy] 220 | ---- 221 | totalSlides = { 222 | js (/$$(".step", byId('impress')).length/) 223 | } 224 | ---- 225 | 226 | * `nextSlide` must be implemented so that `deck2pdf` knows how to jump from one slide to another (or one transition 227 | to another). For example: 228 | 229 | [source,groovy] 230 | ---- 231 | nextSlide = { 232 | js('api.next()') 233 | } 234 | ---- 235 | 236 | As the Groovy profile is stateful, you can for example keep track of the slide number and have a distinct operation 237 | depending on the slide number: 238 | 239 | [source,groovy] 240 | ---- 241 | int curSlide = 0 242 | nextSlide = { 243 | curSlide++ 244 | switch (curSlide) { 245 | case 1: 246 | js 'api.next()' 247 | break; 248 | case 2: 249 | js 'api.goto(2)' 250 | break; 251 | default: 252 | js "api.goto($curSlide)" 253 | } 254 | } 255 | ---- 256 | 257 | * `pause` lets you change the duration before next slide is exported, in milliseconds. Currently, you are not allowed 258 | to set a distinct pause for each slide, the change is global. For example: 259 | 260 | [source,groovy] 261 | ---- 262 | pause = 2000 263 | ---- 264 | 265 | The file name for a Groovy profile *must* end with `.groovy`. 266 | 267 | ===== Accessing command line options 268 | 269 | It is possible for a Groovy profile to access command line options. This can be useful if you want the profile to be 270 | configurable from command line. Accessing the command line options is easy, since the named parameters from the 271 | command line are directly exported in the script through the `options` variable: 272 | 273 | [source,groovy] 274 | ---- 275 | setup { 276 | if (Boolean.valueOf(options.verbose)) { 277 | // --verbose=true on command line 278 | println "Hello, I'm in verbose mode!" 279 | } 280 | String mode = options.mode?:'auto' 281 | switch (mode) { 282 | case 'auto': 283 | ... 284 | break; 285 | case 'skip': 286 | ... 287 | break; 288 | } 289 | 290 | } 291 | ---- 292 | 293 | === Using a custom profile 294 | 295 | Once you've written a new profile, you can use it with the `--profile` switch: 296 | 297 | ---- 298 | deck2pdf --profile=/path/to/profile.groovy slides.html slides.pdf 299 | ---- 300 | 301 | Of course, you can submit a pull request so that we include your profile into the distribution! 302 | 303 | == Custom fonts 304 | 305 | You'll need to read this section if you have custom fonts in your presenation. 306 | 307 | === JavaFX 3.0: CSS3 @font-face 308 | 309 | In order to use custom fonts in your presentation, as defined using the CSS3 +@font-face@, you need to use at least JavaFX 3.0 (available in JDK 8). Otherwise, the embedded browser will fall back to using the default system font. 310 | 311 | Here's an example custom font sourced from http://www.google.com/fonts[Google Fonts]: 312 | 313 | [source,html] 314 | ---- 315 | 316 | ---- 317 | 318 | This link element imports the following CSS: 319 | 320 | [source,css] 321 | ---- 322 | @font-face { 323 | font-family: 'Yanone Kaffeesatz'; 324 | font-style: normal; 325 | font-weight: 400; 326 | src: local('Yanone Kaffeesatz Regular'), local('YanoneKaffeesatz-Regular'), url(http://themes.googleusercontent.com/static/fonts/yanonekaffeesatz/v4/YDAoLskQQ5MOAgvHUQCcLbvy90DtE_Pg_qiF9bHvTzw.ttf) format('truetype'); 327 | } 328 | @font-face { 329 | font-family: 'Yanone Kaffeesatz'; 330 | font-style: normal; 331 | font-weight: 700; 332 | src: local('Yanone Kaffeesatz Bold'), local('YanoneKaffeesatz-Bold'), url(http://themes.googleusercontent.com/static/fonts/yanonekaffeesatz/v4/We_iSDqttE3etzfdfhuPRUgbSk09ekaEjkXjfj0Ujx8.ttf) format('truetype'); 333 | } 334 | ---- 335 | 336 | You can now use these two combinations of +font-family+, +font-style+ and +font-weight+ in your presentation. Unlike a normal browser (e.g., Chrome, Firefox, etc), you cannot use a font combination that is not represented here (or on your system). If you attempt to use a combination not represented here (such as a combination that include `font-style: italic;`), the embedded browser will fall back to using the default font. 337 | 338 | Aside from that exception, custom fonts should just work when using JavaFX 3.0. 339 | 340 | === JavaFX 2.2: Explicit font loading 341 | 342 | If you you're using JavaFX 2.2 (available in JDK 7), you can still use custom fonts, but you must load them explicitly before the embedded browser loads the presentation. 343 | 344 | First, download the TTF file for each font you want to use and copy it to a directory of your choice. The files should be named using the hyphenated form shown in the CSS above.
