Figure 2. 30.  Curve with Flatness 60   
Both of these programs draw an  identical curve. The only difference between the two is 
in the flatness, which is specified on line 2. 
Closed Paths 
When the end point of a path connects to its starting point, the path is said to be  closed. A 
closed path can be stroked, in the same manner  as an open path, or it can be filled with 
gray-scale...

This program is similar to the previous one.  In this case, we choose to fill the path 
instead of stroking it. We select a shade of  gray for filling the path (.5, a value directly 
between black and white) with the GPAT  (set Gray PATtern) command on line 3. 
First, we construct the path by drawing arcs around the...

in the next two figures, the rule determines  areas that are deemed to be inside the path.

With 1 specified for the rule parameter of FILL, the method for determining whether a 
point is inside the path involves drawing a ray from that point in any direction and count-
ing the number of times the ray crosses segments of the path. The point is said to be 
inside the path if the result is an odd number; if the result is an even number, the point is 
said to be outside the path. 
The non-zero winding rule also draws a ray from a point in any direction to determine...

Printing with Character Paths 
When a resident scalable (outline) font is selected, you can treat a character as a path and 
add it to the current path. The PRESCRI BE command is CPTH (Character PaTH). 
Paths created with the CPTH command can be ei ther stroked or filled. See the following 
example.

Next, the SFNT (Select current FoNT by typeface) on line 5 selects Helvetica Bold, a 
scalable (outline) font as the  current font and scales the font  to a height of 54 points. Use 
of SFNT and other font selection commands are explained more fully in  PRESCRIBE 
Commands Command Reference .
The PMZP command on line 6 moves the cursor  to the point that is 72 points (1 inch) 
from the left edge limit and 2 inches from the top edge limit.

Raster Graphics
2-35
raster data represents a repeating pattern or an uncompressed (unencoded) pattern. It also 
determines the number of pattern repetitions or bytes of uncompressed data. 
The control byte is a two’s complement value that can be either zer o, positive, or nega-
tive. A negative value (-1 to -127) indicates  that the following byte represents a repeating 
pattern. The number of repetitions of the pattern is determined by the absolute value of 
the control byte. 
If the control byte is...

Figure 2. 36.  Presentation Modes 
A secondary function of the SRO command specifies the width and height of the raster 
area. When a width and height  are explicitly specified, any part  of the raster image that 
extends outside of the area is clipped. 
The STR command specifies the  resolution at which raster data is printed. The default 
resolution is 75 dots per inch,  or the equivalent of 16 physical dots for each raster-line 
dot. The following figure shows how a...

tagged image file format raster data. Both commands  are used with the ENDR (END 
Raster) command. 
Printing Raster Data 
The normal sequence for printing raster data  is to set the presentation mode (and, if 
desired, the height and width of the raster  image area) with the SRO command, to set the 
dot resolution with the STR command, then to print the raster data with the RVRD or 
RVCD/ENDR command pair.

SIMG operation-mode ; 
operation-mode  is a number from 1 to 6 that determines the image model as follows.
