This plugin enables you to embed sketches in Wiki text. You can edit each sketch in an in-place GUI editor on the browser.
The sketches are formatted in a very simple format.
If any of your Wiki viewers may have legacy browsers that don't support HTML5, the sketches won't show up for them. 1)
The best way to see how it works is by seeing
this live demo site Demo site is dead!
The sketches are included by <skcanvas> tag.
When a <skcanvas> tag is included, a sketch is rendered in place of the tag like an image link and an edit button appears below it.
A new button is added to the toolbar in edit page for inserting new sketch. (if you have used EditTable plugin, it works much like the same way)
A simple sketch only consists of a meta element with sketch size information:
<skcanvas> - type: meta size: [200, 100] </skcanvas>
A bit more complex source:
<skcanvas> - type: meta size: [200, 100] - type: rect points: '35,25:137,64' - type: text points: '45,45' text: Example - type: arrow points: '14,46:30,46' - type: arrow points: '142,46:174,46' </skcanvas>
Results in a figure like this:
Path tool is a versatile tool for sketching complex lines.
Below is actually rendered sketches converted to an image. (Source omitted)
You don't have to remember the syntax to use the sketches. There's an edit button below each sketch.
Pressing the edit button brings you to the editor page.
When you want to add a new sketch into a document, press new sketch button in the toolbar in edit mode. You can also edit existing sketch in the edit page by selecting a whole < skcanvas > tag in the wikitext and pressing the button.
This plugin works with dw2pdf plugin to produce PDF with embedded SketchCanvas documents. To enable this feature with text elements in the canvas, you need to download and place a font file named NotoSansCJKjp-Regular.otf from https://noto-website.storage.googleapis.com/pkgs/NotoSansCJKJP-hinted.zip to phplib/ subdirectory.
The SketchCanvas syntax is a YAML document. All text between <skcanvas> and </skcanvas> must be valid YAML document.
Although you don't have to remember them, complete syntax definition can be found at syntax.
There is no configuration option yet.
If a Wiki system could be a knowledge base that everyone can participate, it must be easy to edit all contents for everyone. If it's not easy enough, people would end up using MS Word to write documents.
We already have edittable which makes table editing easy enough, but it's still awkward to include sketches in a Wiki document.
If you had a decent vector graphics editor such as Adobe Illustrator, Inkscape or even Excel, you can only attach rasterized image files and other people couldn't edit them unless the source is separately provided. So I decided to make a format for sketches that meets the requirements:
There is the svgedit plugin that can do similar things with SVG. So why should I bother reinventing wheels?
SketchCanvas is very different from SVG in several aspects:
The main purpose is to sketch quick ideas/concepts and not doing artistic paintings.
Blue areas are planned but not implemented yet. BTW, this image itself was created with SketchCanvas.
