Description
Draws text in the named drawing context. The text is drawn as 2D, 3D, or outline, depending on the mode attribute. The text can be sent as a symbol, a list of symbols, or as a jit.matrix containing char data. When a jit.matrix is used, each row of the matrix is interpreted as one line of text.
Attributes
align [int]
Text alignment mode (default = 0 (left))
Possible values:
0 = 'left'
1 = 'center'
2 = 'right'
3 = 'justify'
depth [float]
The depth (z extent) of the 3D geometry relative to the height of the font (default = 0.) If a depth of 0 is used, no extruded character sides are generated, which will draw much faster. Only valid if mode is 3d.
floatchomp [int]
Toggles floating-point precision rounding.
floatplaces [int]
When float point precision rounding is enabled set via the floatchomp attribute, this value sets the precision of the number.
fontname [symbol]
Set the name of the font type used.
fontsize [int]
Set the font size in pixels (default = 9). Only valid if mode is 2d.
leadscale [float]
The leading between multiple rows of text as a multiple of the standard leading. (default = 1.)
line_length [float]
The line length specified in gl-units for mode 3d and outline, and in pixels for 2d. Lines of text extending beyond this value will wrap to the next line. The default value of -1 specifies no line length, and therefore no wrapping.
mode [symbol]
Defines how the rendered text is drawn (default = 2d).
Possible values:
'2d'
'3d'
'outline'
plane [int]
The plane of a multi-plane char input matrix which will be interpreted as text. (default = 0)
precision [float]
Sets the precision of the quadratic curve calculation [0 ->inf], The default is 1.0
screenmode [int]

The origin of the text on screen is determined by the usual projection of the object's position, but the text remains the same size. Rotation is only applied around the z axis. Screenmode is useful for making fixed-size labels which follow objects in space. With screenmode off, the text is transformed in space in the usual way for an OB3D-group object. (default = 1) Only valid if mode is 2d.
