plptex3.3plplot - Man Page

plptex3(wx, wy, wz, dx, dy, dz, sx, sy, sz, just, text)

Writes text at a specified position and inclination and with a specified shear 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, and the reference point is placed at world coordinates (wx, wy, wz)  within the viewport. The inclination and shear 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: plptex3(x, y, z, dx, dy, dz, sx, sy, sz, just, text)

This function is used in example 28.

wx (PLFLT(3plplot), input)

x world coordinate of reference point of string.

wy (PLFLT(3plplot), input)

y world coordinate of reference point of string.

wz (PLFLT(3plplot), input)

z world coordinate of reference point of string.

dx (PLFLT(3plplot), input)

Together with dy and dz , this specifies the inclination of the string.  The baseline of the string is parallel to a line joining (x, y, z)  to (x+dx, y+dy, z+dz) .

dy (PLFLT(3plplot), input)

Together with dx and dz, this specifies the inclination of the string.

dz (PLFLT(3plplot), input)

Together with dx and dy, this specifies the inclination of the string.

sx (PLFLT(3plplot), input)

Together with sy and sz , this specifies the shear of the string.  The string is sheared so that the characters are vertically parallel to a line joining (x, y, z)  to (x+sx, y+sy, z+sz) . If sx = sy = sz = 0.)  then the text is not sheared.

sy (PLFLT(3plplot), input)

Together with sx and sz, this specifies shear of the string.

sz (PLFLT(3plplot), input)

Together with sx and sy, this specifies shear of the string.

just (PLFLT(3plplot), 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 (PLCHAR_VECTOR(3plplot), input)

A UTF-8 character string to be written out.
