text - Geometric procedure

Creates a graphical text
 

Description

Creates a 2D- or 3D-text with variable position, direction, size, width, character slant and typeface (font). The text entity is a vector font type of text continously scalable and with the same appearance when printed as when displayed on screen (true type). In 3D the textplane orientation can be controlled by the TPMODE attribute.

Syntax

text(id, p, dir, str:attributes);

REF	id;
VECTOR	p;
FLOAT	dir;
STRING	str;

Principal parameters

id	- Local identity
p	- Lower left corner of first character in text
dir	- Direction, counterclockwise angle from positive X-axis active
	coordinate system
str	- Text string of characters

Optional parameters

None.

Attributes

PEN	- Pen or colour number
LEVEL	- Level number
BLANK	- Visible(0) or invisible(1)
TSIZE	- Textsize, the height of a capital l "A"
TWIDTH	- Textwidth in % of TSIZE
TSLANT	- Character slant in % of 45 degrees
TFONT	- Font number
TPMODE	- Text plane display mode, 0 or 1
WIDTH	- Linewidth

Examples

text(#2,vec(10,10),0,"Hello everybody !":TSIZE=20);

Creates a size 20 horisontal text with identity = #2 in X = Y = 10.

Comments

6 fonts are delivered with the system. Font 0 is default. Font 1 is serif and more "beautiful" but also slower. Font 2 is and font 3 are non serif and serif fonts conforming to the ISO8859 characterset and font 4 and font 5 are the non serif and serif fonts conforming to the PC characterset. Click below to see what they look like:

 
TFONT=0 Default font
TFONT=1 Serif version of font 0
TFONT=2 ISO8859
TFONT=3 Serif version of font 2
TFONT=4 PC
TFONT=5 Serif version of font 4

Customized fonts can be created using the font editor supplied with the system.

In 3D the TPMODE attribute controls the orientation of the plane in which the text is displayed. TPMODE = 0 (default) always displays the text in the plane of the screen (fully readable in all views). TPMODE = 1 displays the text as a "true" 3D entity in the XY-plane of the coordinate system that was active when the text was created.
