NAME
Shape - A class for creating Excel Drawing shapes
SYNOPSIS
To create a simple Excel file containing shapes using Excel::Writer::XLSX:
#!/usr/bin/perl
use strict;
use warnings;
use Excel::Writer::XLSX;
my $workbook = Excel::Writer::XLSX->new( 'shape.xlsx' );
my $worksheet = $workbook->add_worksheet();
# Add a default rectangle shape.
my $rect = $workbook->add_shape();
# Add an ellipse with centered text.
my $ellipse = $workbook->add_shape(
type => 'ellipse',
text => "Hello\nWorld"
);
# Add a plus shape.
my $plus = $workbook->add_shape( type => 'plus');
# Insert the shapes in the worksheet.
$worksheet->insert_shape( 'B3', $rect );
$worksheet->insert_shape( 'C3', $ellipse );
$worksheet->insert_shape( 'D3', $plus );
DESCRIPTION
The "Excel::Writer::XLSX::Shape" module is used to create Shape objects for
Excel::Writer::XLSX.
A Shape object is created via the Workbook "add_shape()" method:
my $shape_rect = $workbook->add_shape( type => 'rect' );
Once the object is created it can be inserted into a worksheet using the "insert_shape()"
method:
$worksheet->insert_shape('A1', $shape_rect);
A Shape can be inserted multiple times if required.
$worksheet->insert_shape('A1', $shape_rect);
$worksheet->insert_shape('B2', $shape_rect, 20, 30);
METHODS
add_shape( %properties )
The "add_shape()" Workbook method specifies the properties of the Shape in hash "property
=> value" format:
my $shape = $workbook->add_shape( %properties );
The available properties are shown below.
insert_shape( $row, $col, $shape, $x, $y, $scale_x, $scale_y )
The "insert_shape()" Worksheet method sets the location and scale of the shape object
within the worksheet.
# Insert the shape into the worksheet.
$worksheet->insert_shape( 'E2', $shape );
Using the cell location and the $x and $y cell offsets it is possible to position a shape
anywhere on the canvas of a worksheet.
A more detailed explanation of the "insert_shape()" method is given in the main
Excel::Writer::XLSX documentation.
SHAPE PROPERTIES
Any shape property can be queried or modified by the corresponding get/set method:
my $ellipse = $workbook->add_shape( %properties );
$ellipse->set_type( 'plus' ); # No longer an ellipse!
my $type = $ellipse->get_type(); # Find out what it really is.
Multiple shape properties may also be modified in one go by using the "set_properties()"
method:
$shape->set_properties( type => 'ellipse', text => 'Hello' );
The properties of a shape object that can be defined via "add_shape()" are shown below.
name
Defines the name of the shape. This is an optional property and the shape will be given a
default name if not supplied. The name is generally only used by Excel Macros to refer to
the object.
type
Defines the type of the object such as "rect", "ellipse" or "triangle":
my $ellipse = $workbook->add_shape( type => 'ellipse' );
The default type is "rect".
The full list of available shapes is shown below.
See also the "shapes_all.pl" program in the "examples" directory of the distro. It creates
an example workbook with all supported shapes labelled with their shape names.

text
This property is used to make the shape act like a text box.
my $rect = $workbook->add_shape( type => 'rect', text => "Hello\nWorld" );
The text is super-imposed over the shape. The text can be wrapped using the newline
character "\n".
id
Identification number for internal identification. This number will be auto-assigned, if
not assigned, or if it is a duplicate.
format
Workbook format for decorating the shape text (font family, size, and decoration).
start, start_index
Shape indices of the starting point for a connector and the index of the connection. Index
numbers are zero-based, start from the top dead centre and are counted clockwise.
Indices are typically created for vertices and centre points of shapes. They are the blue
connection points that appear when connection shapes are selected manually in Excel.
end, end_index
Same as above but for end points and end connections.
start_side, end_side
This is either the letter "b" or "r" for the bottom or right side of the shape to be
connected to and from.
If the "start", "start_index", and "start_side" parameters are defined for a connection
shape, the shape will be auto located and linked to the starting and ending shapes
respectively. This can be very useful for flow and organisation charts.
flip_h, flip_v
Set this value to 1, to flip the shape horizontally and/or vertically.
rotation
Shape rotation, in degrees, from 0 to 360.
line, fill
Shape colour for the outline and fill. Colours may be specified as a colour index, or in
RGB format, i.e. "AA00FF".
See "COLOURS IN EXCEL" in the main documentation for more information.
line_type
Line type for shape outline. The default is solid. The list of possible values is:
dash, sysDot, dashDot, lgDash, lgDashDot, lgDashDotDot, solid
valign, align
Text alignment within the shape.
Vertical alignment can be:
Setting Meaning
======= =======
t Top
ctr Centre
b Bottom
Horizontal alignment can be:
Setting Meaning
======= =======
l Left
r Right
ctr Centre
just Justified
The default is to centre both horizontally and vertically.
scale_x, scale_y
Scale factor in x and y dimension, for scaling the shape width and height. The default
value is 1.
Scaling may be set on the shape object or via "insert_shape()".
adjustments
Adjustment of shape vertices. Most shapes do not use this. For some shapes, there is a
single adjustment to modify the geometry. For instance, the plus shape has one adjustment
to control the width of the spokes.
Connectors can have a number of adjustments to control the shape routing. Typically, a
connector will have 3 to 5 handles for routing the shape. The adjustment is in percent of
the distance from the starting shape to the ending shape, alternating between the x and y
dimension. Adjustments may be negative, to route the shape away from the endpoint.
stencil
Shapes work in stencil mode by default. That is, once a shape is inserted, its connection
is separated from its master. The master shape may be modified after an instance is
inserted, and only subsequent insertions will show the modifications.
This is helpful for Org charts, where an employee shape may be created once, and then the
text of the shape is modified for each employee.
The "insert_shape()" method returns a reference to the inserted shape (the child).
Stencil mode can be turned off, allowing for shape(s) to be modified after insertion. In
this case the "insert_shape()" method returns a reference to the inserted shape (the
master). This is not very useful for inserting multiple shapes, since the x/y coordinates
also gets modified.
TIPS
Use "$worksheet->hide_gridlines(2)" to prepare a blank canvas without gridlines.
Shapes do not need to fit on one page. Excel will split a large drawing into multiple
pages if required. Use the page break preview to show page boundaries superimposed on the
drawing.
Connected shapes will auto-locate in Excel if you move either the starting shape or the
ending shape separately. However, if you select both shapes (lasso or control-click), the
connector will move with it, and the shape adjustments will not re-calculate.
EXAMPLE
#!/usr/bin/perl
use strict;
use warnings;
use Excel::Writer::XLSX;
my $workbook = Excel::Writer::XLSX->new( 'shape.xlsx' );
my $worksheet = $workbook->add_worksheet();
# Add a default rectangle shape.
my $rect = $workbook->add_shape();
# Add an ellipse with centered text.
my $ellipse = $workbook->add_shape(
type => 'ellipse',
text => "Hello\nWorld"
);
# Add a plus shape.
my $plus = $workbook->add_shape( type => 'plus');
# Insert the shapes in the worksheet.
$worksheet->insert_shape( 'B3', $rect );
$worksheet->insert_shape( 'C3', $ellipse );
$worksheet->insert_shape( 'D3', $plus );

TODO
• Add shapes which have custom geometries.
• Provide better integration of workbook formats for shapes.
• Add further validation of shape properties to prevent creation of workbooks that will
not open.
• Auto connect shapes that are not anchored to cell A1.
• Add automatic shape connection to shape vertices besides the object centre.
• Improve automatic shape connection to shapes with concave sides (e.g. chevron).
