2.2.5 Diagrams (drawio)

Drawio offers extensive drawing possibilities for process flowcharts, infographics and other visualizations on a wiki page. Descriptive graphics like process chains or decision trees can be constructed directly on a wiki page.

Click Insert. This opens a dialog box. The following properties can be set:
1. Name: Name of the drawio diagram is used for the image name that stores the diagram in the wiki.
2. Edit mode v5.2+: Fullscreen view opens the drawio editor in the entire browser window, Page view shows the drawio editor in the page content area.
3. Image description: Alternative image text for screenreaders. It is not displayed on the page in view mode.
4. Image alignment: Horizontal alignment of the diagram in the page content area.
Click Insert. This inserts the <drawio>-tag in your page.

Remove auto-resizing auf Drawio images (PNG only) -v5.1

The following information only applies to Drawio diagrams that are embedded as PNG.

Avoid auto-resizing of linked shapes:By default, drawio images are resized to always fit into the content area. Since the links are implemented as map coordinates, the png image cannot be resized without breaking the link boundaries. To avoid this, you can disable automatic resizing of your drawio images with the following css.

Add the following rules to MediaWiki:Common.css

/*Drawio png - do not auto-resize preview images when links are added directly to the shapes */
div[id*=drawio-img-box] {
    overflow-x:scroll 
}

/*Drawio png - do not auto-resize preview images when links are created as image maps from file description page */
div[id*=drawio-img-box] img {
    height: initial;
    max-width: initial;
    width: initial;
}

This will remove the auto-resizing behavior from all Drawio preview images.

To apply this styling to only some Drawio images, you could add a wrapper to these images in source editing mode. For example:

<div class="drawio-linked">
<drawio filename="processmap" alt="Processmap showing the management, core, and supporting processes ">
</drawio>
</div>

In this case, do not add the above styles to your Common.css, but use these rules instead:

/*Drawio png - do not auto-resize drawio diagrams that are wrapped in a container with class drawio-linked */
.drawio-linked {
    overflow-x:scroll 
}

.drawio-linked img {
    height: initial!important;
    max-width: initial!important;
    width: initial!important;
}

PNG and SVG Format v5.1.1+

Up to BlueSpice 5.1, Drawio diagrams were always saved and previewed in PNG format.

Starting with BlueSpice 5.1.1, newly created diagrams are saved and previewed in SVG format. Along with the diagram, a link to the versioning page is also generated in BlueSpice 5.1.1.

The link to the versioning page can be hidden for the entire wiki using the MediaWiki:Common.css page:

/* hide drawio caption for BlueSpice 5.1.1 */
.drawio-caption {display:none;}

Drawio diagrams in table cells

It is not recommended to maintain Drawio diagrams in table cells since the editing experience and the display in PDF documents can cause issues. An alternative is to Create the Drawio file on a separate page and then insert the image file with proper dimensions in any table cell in the wiki. If you decide to create Drawio files directly in a table cell, you can control the sizing in PDF exports by adding the following CSS to MediaWiki:Common.css:

/** ERM42590*/
.pdfcreator-type-page .drawio-table-test img {
	max-width: 10cm !important;
}

Import of existing diagrams

Visio diagrams

You can import files with the extension .vsdx directly into the Drawio editor and edit them further. To do this, create a diagram on a wiki page. In the Drawio editor, choose File> Import From> Device. You can then edit the imported diagram.

Configuration

Wiki admins can configure the following settings in the Configuration manager:
