DECVEC Draw Vector:
Draw a vertical or horizontal line.
Source:
Application
Destination:
Level 3 Extension
Format
CSI Ps1 ; Pn2 ; Pn3 ; Pn4 ; Pn5 ! |
Description
The selective parameter options are as follows:
Ps1 Action
0 Draw X (horizontal) line.
1 Draw Y (vertical) line.
Select the numeric parameters as follows:
Pn Meaning
Pn2 X start position
Pn3 Y start position
Pn4 Line length
Pn5 Line width
DECVEC does not modify the active position.
The unit for numeric parameters is selected using the Select Size
Unit (SSU) command Positioning Unit Mode (PUM) has no effect on
DECVEC unit size.
For an X line, Pn4 specifies horizontal length and Pn5 specifies
vertical width. For a Y line, Pn4 specifies vertical length and Pn5
specifies horizontal width. Since a vector has length and width, it is
considered a filled rectangle. The rectangle is not centered on the
endpoints. DECVEC rectangles are positioned identically relative to
the endpoints as relative vectors. See DECRVEC.
Error Handling
If Ps1 is any value other than 0 or 1, the entire command is ignored.
Missing parameters are interpreted as 0. If the printer receives a
DECVEC command with too many parameters, the first five are used
and others are ignored.
If the requested line is less than 1 pixel long, the printer draws a line
1 pixel long. If the requested line is less than 1 pixel wide, the printer
draws a line 1 pixel wide.
Do not rely upon the defaults for Pn4 and Pn5. Define the vector to
be at least 1 pixel long and 1 pixel wide. Poor quality may result
when processing very short or very thin vectors.
Margin settings do not affect vectors. DECVEC may draw lines that
extend beyond the margins, but not out of the printable area. Vectors
that extend outside of the printable area are clipped.
