create a text structure with metadata
Text(format, arguments, options)
string containing "%1"
The Text command is used by GetMath when extracting math and text from a canvas. It packages a text expression up into a record where it can be saved alongside other information relevant to the context of the canvas application, such as the id, position, and annotation.
It can be useful to use the Text command when constructing a canvas that will later be deployed to Maple Learn.
The Text command supports mixed text and math notation. When given a first argument format string that contains the % character followed by a number, n, the text will display the nth argument in place of %n.
The Text command supports the following style options:
bold = true; when true, make the text bold
color = string or ColorTools:-Color; set the color of the text
fontsize = posint; control the size of the font
sans = true; use a sans-serif font
container = "group" or "textbox"; Maple Learn has two kinds of boxes that can contain text: a textbox or a group. Use this option to indicate which kind of box the text should be added to.
custom = string; use this option to give a custom name to this text area, which can be used by GetElements to locate this item later.
position = [x,y]; use this option to specify a pixel-position for the top left corner of the text
