Properties

Value — Vertical alignment

character vector | string scalar

Vertical alignment of an inline document element, specified as one of these values:

• "superscript" or "super" — Aligns the element as superscript to the parent element.

• "subscript" or "sub" — Aligns the element as subscript to the parent element.

• "baseline" — Aligns the baseline of the element with the baseline of the parent element.

• "text-top" — Aligns the top of the element with the top of the content area of the parent element. This value is not supported for Word documents.

• "text-bottom" — Aligns the bottom of the element with the bottom of the content area of the parent element. This value is not supported for Word documents.

• length — amount by which the element is raised or lowered from the baseline of the parent element, specified as character vector or string scalar that contains a number followed by an abbreviation for a unit of measurement. For example, "10px" specifies 10 pixels. Valid abbreviations are:

  Unit Name	Unit Abbreviation
  pixels (not supported for Word documents)	px
  centimeters	cm
  inches	in
  millimeters	mm
  picas	pc
  points	pt
  percentage of the line height (not supported for Word documents)	%

See the vertical-align property in the CSS specification.

If you do not provide a VerticalAlign object, the alignment defaults to the baseline alignment. If you provide a VerticalAlign object, but do not specify the alignment, the alignment defaults to the superscript alignment.

Example: "text-top"

Example: "0.25in"

Example: "50%"

Id — Object identifier

character vector | string scalar

Object identifier, specified as a character vector or string scalar. The DOM API generates a session-unique identifier when it creates the document element object.

Attributes:

GetAccess	public
SetAccess	public
NonCopyable	true

Data Types: char | string

Tag — Tag

character vector | string scalar

Tag, specified as a character vector or string scalar. The DOM API generates a session-unique tag as part of the creation of this object. The generated tag has the form CLASS:ID, where CLASS is the object class and ID is the value of the Id property of the object. Use this value to help identify where an issue occurs during document generation.

Attributes:

GetAccess	public
SetAccess	public
NonCopyable	true

Data Types: char | string

Examples

Vertically Align Text as Superscript

Align text as superscript to the text in the parent paragraph. Creating a VerticalAlign object without providing an input argument sets the alignment to superscript.

import mlreportgen.dom.*; 
doctype = 'html';
d = Document('test',doctype);
p = Paragraph('e = mc');

t = Text('2');
t.Style = {VerticalAlign()};
append(p,t);
append(d,p);

close(d);
rptview('test',doctype);

Align Image with Bottom of Text

Align the bottom of an image with the bottom of the surrounding text by specifying 'text-bottom'.

import mlreportgen.dom.*;
doctype = 'html';
d = Document('mydoc',doctype);

p = Paragraph('This image ');
p.FontSize = '20';
im = Image('image_to_align.png');
im.Style = {VerticalAlign('text-bottom')};
t = Text(' is aligned with the bottom of the surrounding text.');
append(p,im);
append(p,t);
append(d,p);

close(d);
rptview('mydoc',doctype);
