You can create your own custom stencils (shapes) in draw.io by describing their geometry, connection points and styles of the components in your stencil in an XML format.

Tip: You can drag a custom stencil from the drawing canvas into your Scratchpad, or to a custom library if you want to save or share your custom shapes. Click File > New Library to create a new custom library.

The basic draw.io stencils use XML. Click Arrange > Insert > Shape to open the Edit Shape dialog where you can see the XML structure of the stencil. Let's customise this stencil to be a large L with a vertical line inside.

The top level element is 'shape'. So enter:

Its attributes are:

• name - stencil name.
• h - height.
• w - width.
• aspect - if 'variable', you can have any aspect ratio. if 'fixed', h and w are fixed to the ratio you defined in h and w.
• strokewidth - 'inherit' sets strokewidth to the style you define in the UI. Set it to a positive number and it will be fixed to that width.

The shape block can contain three child elements defined in the following order:

• - connection points for edges.
• - geometry defined here will have shadows.
• - the rest of the geometry.

We will deal with connections later.

Let's create the geometry for the background (the L part of the stencil):

Webtolayers 1 1 1 – converts websites to photoshop documents.

The coordinate 0, 0 is always the top left point. The bottom right is w, h, so in this case it's 100, 50.

Now add some foreground geometry (the vertical line inside the L):

Every geometry element has to have a defined stroke. It can be stroke, fill or fillstroke. Stroke is stroke without fill, fill is fill without stroke, and fillstroke is both fill and stroke. First, the geometry should be defined and preferably the next line should be the stroke type.

After all this, our shape should be looking something like this:

Notice the stroke exception in the case of the background geometry. You don't define it after the background geometry, but instead as the first line of the foreground block.

Click Preview and you should see:

There are 4 types of geometry elements:

• - attributes 'x', 'y', 'w', 'h', all required decimals
• - attributes 'x', 'y', 'w', 'h', all required decimals. Also 'arcsize' is an optional decimal attribute defining how large the corner curves are.
• - attributes 'x', 'y', 'w', 'h', all required decimals.
• - a general case of geometry, used for more complex shapes.

Path is a similar structure as path in SVG. It should start with a where 'x' and 'y' define the coordinate. After move, an arbitrary number of geometry elements should follow.

Path elements can be:

• - to attributes required decimals (x,y).
• -to attributes required decimals (x,y).
• - to required decimals (x2,y2) via control point required decimals (x1,y1).
• - to required decimals (x3,y3), via control points required decimals (x1,y1) and (x2,y2).
• - this doesn't follow the HTML Canvas signatures, instead it's a copy of the SVG arc command. The SVG specification gives the best description of its behaviors. The attributes are named identically, they are decimals and all required.
• ends the current subpath and causes an automatic straight line to be drawn from the current point to the last move point of the current subpath.

When the subpath is finished, there are two options. The first is to finish it with , which makes is visually open. The second option is to use and then , which will close the current subpath. A subpath is a segment which starts with a and ends with a or another . A single can contain multiple subpaths, but all of them will use the same style. And if they overlap, the same fill rule applies as for SVG.

Miss kitty game.

The first element of geometry will use the shadow style if needed, but the rest will not.

3 will be free ep 6 24. The element defines the connection points of the stencil, where edges can be connected.

This adds 4 connection points at the corresponding coordinates. Note the coordinates are relative. x=0 is 0, x=1 is full width. Same for y.

When you hover over the unselected shape, connection points appear as a small x. Mac os x 10 11 software update. Drag edges from these connection points or via the blue arrows.

Style functions similar to the SVG style specification. Until you have defined a specific style, the style applied to the stencil will be in effect.

Style types are:

• alpha - defines the alpha level, the opposite of transparency. Attribute is alpha and range is 0-1, decimal. 0 being fully transparent and 1 being solid.

• strokewidth - defines the stroke width in pixels. Attributes are width which is decimal and fixed is optional, default 0 being scaling with resize and 1 for fixed stroke width regardless of scaling.
• dashed - toggles the dashed line style. Attribute is dashed. 0 for solid line, 1 for dashed.
• dashpattern - defines a custom dashed line style. Attribute is pattern and is an array. The numbers in the array define for how many points there is a line, how many points fo a pause, then how many points for a line again, and so on. Imagine the numbers as on/off alternating until the end of the array and then starting over. So defines a line length 5, pause of 1, even longer line of 8, another pause of 1 and then starting over.
• miterlimit - same as in SVG. Attribute is limit, a decimal number. It defines the 'edginess' of line joins. The larger the number, the bigger spikes are allowed on sharp joins. The limit attribute defines the cutoff amount for spikes.
• linejoin - defines the type of line joining. Attribute is join and can be miter, round or bevel, same as in SVG. Default is miter, and it produces straight sharp edges. Round as the name says gives rounded joins. Bevel is the middle solution, as it produces 'rounded' joins, but instead a curve, a straight line.
• linecap- defines the type of line end. Attribute is cap and can be flat, square or round, same as in SVG. Default is flat, and it produces a square edge right at the end of the line. Round as the name says gives rounded ending, after the line end, so the line is a bit longer. Squareis the middle solution, as it produces 'rounded' ends, but instead a circular curve, a squared straight line at the end.

There are some more style that are related to text.

Text

Text is added using the text element. You can add text to the foreground or background (before or , but be aware that background text may be hidden by foreground elements, especially those that are filled. Text uses the following format:

Required attributes are str, x and y. Align, valign, localized, vertical, rotation and align-shape are all optional.

• str - defines the actual text the stencil will include and is a string. x and y are label coordinates and use a decimal value.
• align - defines the horizontal alignment and its self-descriptive values are: left, center and right.
• valign -defines the vertical alignment. Its possible values are top, middle and bottom.
• vertical - 1 for text that is rendered vertically, 0 (default) for horizontal text.
• rotation - defines the text rotation and is in the range of 0.0-360.0.
• align-shape - 1 for a text label that rotates with the shape, 0 for a fixed text label.

The styles related to text are:

• fontsize - attribute is size and is a decimal value. Defines font size.
• fontstyle - attribute is style and is an ORed bit pattern of bold (1), italic (2) and underline (4), i.e. bold underline is '5'
• fontfamily - attribute is family and is a string defining the typeface to be used.

After adding the text to the custom shape, as well as the connectors, click Preview.

Unless you defined a style inside the stencil, it will use the default style that is applied to it. In the case of the above example, you can change the fillcolor and strokecolor and it will affect the whole stencil.

Let's say we want to keep the behavior of the outline stroke (it changes as we change the strokecolor in the UI), but we want that vertical line to always be white. Lets call the outline geometry and the vertical line . We should do conceptually something like this:

Now assume we have another line we will call which is declared after and we want it to have the default stroke color. Since we already defined strokecolor to be white, we need a mechanism to undo this. For this reason the format has a stack mechanism. By entering a element, we save the current style on the stack. If we use a later, we reset the current style to the last save that is in the stack. The stack uses the standard LIFO (last in, first out) structure.

The number of and elements should match.

As an example, let's change our L shape to include two lines in the foreground : the first vertical line is grey, and the second one is back to the default stroke color.
