Class: FontBase
Description
Computes the layout of the given text according to a given rectangular region size, layout flags and other parameters.
(table) = FontBase:layoutText(text,width,height,flags,letterSpacing,lineSpacing,tabSpace,breakChar)
Refer to TextField:setLayout for a description of the arguments.
The returned table contains the following fields:
- x,y,w,h: computed bounding box of the full text
- lines: the number of lines used to display the text
- parts: information about individual chunks of texts
Each table in the part field of the returned table describes the placement of chunks of text. Their fields are:
- text: the text to display in this chunk
- x,y,w,h: computed bounding box of this chunk
- dx,dy: coordinates to draw this chunk at
- sep: separator character that came just after this chunk in text block
- line: line number this chunk belongs to
Parameters
text: (string)
width: (number)
height: (number)
flags: (number, default=FontBase.TLF_NOWRAP)
letterSpacing: (number, default = 0)
lineSpacing: (number, default = 0)
tabSpace: (number, default = 4)
breakChar: (string) optional
Return values
Returns (table) a table describing how to draw the given text
