Binary Work Data: Binary work data is defined as binary work coordinates (2-dimensional
coordinates). Work data is used to implement polygon painting. Polygon outline data is created
with the FTRAP command, etc. and the created figure data is used to delineate the rendering figure.
For example, if the POLYGON4C command is used jointly for work, the work area polygon can
be drawn in the rendering area with the specified color value. The configuration of binary work data
is shown in figure 4-11.

Specified Color Data: Specified color data is defined directly in drawing parameters COLOR,
COLOR0, COLOR1, LINE COLOR0, and LINE COLOR1. When the Q2 is used for 8-bit/pixel
operation, the same color palette number is defined in the upper 8 bits and lower 8 bits by the
drawing parameter color specification. When the Q2 is used for 16-bit/pixel operation, the R, G,
and B values are defined directly by the drawing parameter color specification.
However, with LINEW and RLINEW, 0 or 1 is defined in the rendering attribute EOS bit.

Rendering Attributes
With the Q2, seven rendering attributes can be specified. The rendering attributes are embedded in
the commands, and can be specified on an individual command basis. Figure 4-12 shows the bit
arrangement for rendering attributes.
