Description
Compute the layout of the given text according to a given rectangular region size, layout flags and other parameters.
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 describe 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
(table) = FontBase:layoutText(text,width,height,flags,letterSpacing,lineSpacing,tabSpace,breakChar)
'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
Returns (table) A table describing how to draw the given text.
