## SYNOPSIS

**plptex**(

*x*,

*y*,

*dx*,

*dy*,

*just*,

*text*)

## DESCRIPTION

Writes text at a specified position and inclination within the viewport. Text is clipped at the viewport boundaries. The reference point of a string lies along a line passing through the string at half the height of a capital letter. The position of the reference point along this line is determined by *just*, the reference point is placed at world coordinates (*x*, *y*) within the viewport. The inclination of the string is specified in terms of differences of world coordinates making it easy to write text parallel to a line in a graph.

Redacted form: **plptex(x, y, dx, dy, just, text)**

This function is used in example 2-4,10,12-14,20,23,24,26.

## ARGUMENTS

*x*(PLFLT, input)- x coordinate of reference point of string.
*y*(PLFLT, input)- y coordinate of reference point of string.
*dx*(PLFLT, input)-
Together with
*dy*, this specifies the inclination of the string. The baseline of the string is parallel to a line joining (*x*,*y*) to (*x*+*dx*,*y*+*dy*). *dy*(PLFLT, input)-
Together with
*dx*, this specifies the inclination of the string. *just*(PLFLT, input)-
Specifies the position of the string relative to its reference point. If
*just*=0., the reference point is at the left and if*just*=1., it is at the right of the string. Other values of*just*give intermediate justifications. *text*(const char *, input)-
The string to be written out.
