Clicking (or tapping with a finger) on the outer region causes the viewport to zoom out. - * Clicking anywhere within the middle, "pan", region centers the image on the spot clicked. - * Finally, clicking in the center hotspot will center the image on the spot clicked and zoom - * in half a zoom level. - * - *

As before, you can drag to pan anywhere. - * - *

If you have navigation tools for mouse users that hover over the image container, it - * is recommended that any click events on them are kept from bubbling, otherwise the click - * will propagate to the touch ui. One way is to use the - * {@link bigshot.Browser#stopMouseEventBubbling} method: - * - * @example - * var browser = new bigshot.Browser (); - * browser.stopMouseEventBubbling (document.getElementById ("myBigshotControlDiv"));

Creating a Wrapping Image

- * - *

If you have set the wrapX or wrapY parameters in the {@link bigshot.ImageParameters}, the - * image must be an integer multiple of the tile size at the desired minimum zoom level, otherwise - * there will be a gap at the wrap point: - * - *

The way to figure out the proper input size is this: - * - *

    - *

  1. Decide on a tile size and call this tileSize.

    2. - *

  2. Decide on a minimum integer zoom level, and call this minZoom.

    3. - *

  3. Compute tileSize * 2-minZoom, call this S.

    4. - *

  4. The source image size along the wrapped axis must be evenly divisible by S.

    5. - *
- * - *

An example:

- * - *
    - *

  1. I have an image that is 23148x3242 pixels.

    2. - *

  2. I chose 256x256 pixel tiles: tileSize = 256.

    3. - *

  3. When displaying the image, I want the user to be able to zoom out so that the - * whole image is less than or equal to 600 pixels tall. Since the image is 3242 pixels - * tall originally, I will need a minZoom of -3. A minZoom of -2 would only let me - * zoom out to 1/4 (2-2), or an image that is 810 pixels tall. A minZoom of -3, however lets me - * zoom out to 1/8 (2-3), or an image that is 405 pixels tall. Thus: minZoom = -3

    4. - *

  4. Computing S gives: S = 256 * 23 = 256 * 8 = 2048

    5. - *

  5. I want it to wrap along the X axis. Therefore I may have to adjust the width, - * currently 23148 pixels.

    6. - *

  6. Rounding 23148 down to the nearest multiple of 2048 gives 22528. (23148 divided by 2048 is 11.3, and 11 times 2048 is 22528.)

    7. - *

  7. I will shrink my source image to be 22528 pixels wide before building the image pyramid, - * and I will set the minZoom parameter to -3 in the {@link bigshot.ImageParameters} when creating - * the image. (I will also set wrapX to true.)

Requires WebGL or CSS3D support. - * (Note: See {@link bigshot.VRPanorama#dispose} for important information.) - * - *

Creating a Cube Map

- * - *

The panorama consists of six image pyramids, one for each face of the VR cube. - * Due to restrictions in WebGL, each texture tile must have a power-of-two (POT) size - - * that is, 2, 4, ..., 128, 256, etc. Furthermore, due to the way the faces are tesselated - * the largest image must consist of POT x POT tiles. The final restriction is that the - * tiles must overlap for good seamless results. - * - *

The MakeImagePyramid has some sensible defaults built-in. If you just use the - * command line: - * - * 

- * java -jar bigshot.jar input.jpg temp/dzi \
- *     --preset dzi-cubemap \ 
- *     --format folders
- *
- * - *

You will get 2034 pixels per face, and a tile size of 256 pixels with 2 pixels - * overlap. If you don't like that, you can use the overlap, face-size - * and tile-size parameters. Let's take these one by one: - * - *

    - *

  • overlap: Overlap defines how much tiles should overlap, just to avoid - * seams in the rendered results caused by finite numeric precision. The default is 2, which - * I've found works great for me.

    • - *

  • tile-size: First you need to decide what POT size the output should be. - * Then subtract the overlap value. For example, if you set overlap to 1, tile-size - * could be 127, 255, 511, or any 2n-1 value.

    • - *

  • face-size: Finally, we decide on a size for the full cube face. This should be - * tile-size * 2n. Let's say we set n=3, which makes each face 8x8 tiles at the most zoomed-in - * level. For a tile-size of 255, then, face-size is 255*23 = 255*8 = 2040.

    • - *
- * - *

A command line for the hypothetical scenario above would be: - * - * 

- * java -jar bigshot.jar input.jpg temp/dzi \
- *     --preset dzi-cubemap \ 
- *     --overlap 1 \
- *     --tile-size 255 \
- *     --face-size 2040 \
- *     --format folders
- *
- * - *

If your tile size numbers don't add up, you'll get a warning like: - * - * 

- * WARNING: Resulting image tile size (tile-size + overlap) is not a power of two: 255
- *
- * - *

If your face size don't add up, you'll get another warning: - * - * 

- * WARNING: face-size is not an even multiple of tile-size: 2040 % 254 != 0
- *
- * - *

Integration With SaladoPlayer

- * - *

SaladoPlayer is a cool - * Flash-based VR panorama viewer that can display Deep Zoom Images. - * It can be used as a fallback for Bigshot for browsers that don't - * support WebGL. - * - *

Since Bigshot can use a Deep Zoom Image (DZI) via a {@link bigshot.DeepZoomImageFileSystem} - * adapter, the common file format is DZI. There are two cases: The first is - * when the DZI is served up as a folder structure, the second when - * we pack the DZI into a Bigshot archive and serve it using bigshot.php. - * - *

Serving DZI as Folders

- * - *

This is an easy one. First, we generate the required DZIs: - * - * 

- * java -jar bigshot.jar input.jpg temp/dzi \
- *     --preset dzi-cubemap \ 
- *     --format folders
- *
- * - *

We'll assume that we have the six DZI folders in "temp/dzi", and that - * they have "face_" as a common prefix (which is what Bigshot's MakeImagePyramid - * outputs). So we have, for example, "temp/dzi/face_f.xml" and the tiles for face_f - * in "temp/dzi/face_f/". Set up Bigshot like this: - * - * 

- * bvr = new bigshot.VRPanorama (
- *     new bigshot.VRPanoramaParameters ({
- *             container : document.getElementById ("canvas"),
- *             basePath : "temp/dzi",
- *             fileSystemType : "dzi"
- *         }));
- *
- * - *

SaladoPlayer uses an XML config file, which in this case will - * look something like this: - * - * 

- * <SaladoPlayer>
- *     <global debug="false" firstPanorama="pano"/>
- *     <panoramas>
- *         <panorama id="pano" path="temp/dzi/face_f.xml"/>
- *     </panoramas>
- * </SaladoPlayer>
- *
- * - *

Serving DZI as Archive

- * - *

This one is a bit more difficult. First we create a DZI as a bigshot archive: - * - * 

- * java -jar bigshot.jar input.jpg temp/dzi.bigshot \
- *     --preset dzi-cubemap \ 
- *     --format archive
- *
- * - *

We'll assume that we have our Bigshot archive at - * "temp/dzi.bigshot". For this we will use the "entry" parameter of bigshot.php - * to serve up the right files: - * - * 

- * bvr = new bigshot.VRPanorama (
- *     new bigshot.VRPanoramaParameters ({
- *             container : document.getElementById ("canvas"),
- *             basePath : "/bigshot.php?file=temp/dzi.bigshot&entry=",
- *             fileSystemType : "dzi"
- *         }));
- *
- * - *

SaladoPlayer uses an XML config file, which in this case will - * look something like this: - * - * 

- * <SaladoPlayer>
- *     <global debug="false" firstPanorama="pano"/>
- *     <panoramas>
- *         <panorama id="pano" path="/bigshot.php?file=dzi.bigshot&amp;entry=face_f.xml"/>
- *     </panoramas>
- * </SaladoPlayer>
- *
- * - *

-``` - -## Philosophy behind marked - -The point of marked was to create a markdown compiler where it was possible to -frequently parse huge chunks of markdown without having to worry about -caching the compiled output somehow...or blocking for an unnecesarily long time. - -marked is very concise and still implements all markdown features. It is also -now fully compatible with the client-side. - -marked more or less passes the official markdown test suite in its -entirety. This is important because a surprising number of markdown compilers -cannot pass more than a few tests. It was very difficult to get marked as -compliant as it is. It could have cut corners in several areas for the sake -of performance, but did not in order to be exactly what you expect in terms -of a markdown rendering. In fact, this is why marked could be considered at a -disadvantage in the benchmarks above. - -Along with implementing every markdown feature, marked also implements [GFM -features][gfmf]. - -## Benchmarks - -node v0.8.x - -``` bash -$ node test --bench -marked completed in 3411ms. -marked (gfm) completed in 3727ms. -marked (pedantic) completed in 3201ms. -robotskirt completed in 808ms. -showdown (reuse converter) completed in 11954ms. -showdown (new converter) completed in 17774ms. -markdown-js completed in 17191ms. -``` - -__Marked is now faster than Discount, which is written in C.__ - -For those feeling skeptical: These benchmarks run the entire markdown test suite 1000 times. The test suite tests every feature. It doesn't cater to specific aspects. - -### Pro level - -You also have direct access to the lexer and parser if you so desire. - -``` js -var tokens = marked.lexer(text, options); -console.log(marked.parser(tokens)); -``` - -``` js -var lexer = new marked.Lexer(options); -var tokens = lexer.lex(text); -console.log(tokens); -console.log(lexer.rules); -``` - -``` bash -$ node -> require('marked').lexer('> i am using marked.') -[ { type: 'blockquote_start' }, - { type: 'paragraph', - text: 'i am using marked.' }, - { type: 'blockquote_end' }, - links: {} ] -``` - -## Running Tests & Contributing - -If you want to submit a pull request, make sure your changes pass the test -suite. If you're adding a new feature, be sure to add your own test. - -The marked test suite is set up slightly strangely: `test/new` is for all tests -that are not part of the original markdown.pl test suite (this is where your -test should go if you make one). `test/original` is only for the original -markdown.pl tests. `test/tests` houses both types of tests after they have been -combined and moved/generated by running `node test --fix` or `marked --test ---fix`. - -In other words, if you have a test to add, add it to `test/new/` and then -regenerate the tests with `node test --fix`. Commit the result. If your test -uses a certain feature, for example, maybe it assumes GFM is *not* enabled, you -can add `.nogfm` to the filename. So, `my-test.text` becomes -`my-test.nogfm.text`. You can do this with any marked option. Say you want -line breaks and smartypants enabled, your filename should be: -`my-test.breaks.smartypants.text`. - -To run the tests: - -``` bash -cd marked/ -node test -``` - -### Contribution and License Agreement - -If you contribute code to this project, you are implicitly allowing your code -to be distributed under the MIT license.
