PROGRAM:
NAME
xgc - X graphics demo
SYNOPSIS
xgc [-toolkitoption ...]
DESCRIPTION
The xgc program demonstrates various features of the X graphics primitives. In X, most of
the details about the graphics to be generated are stored in a resource called a graphics
context (GC). The xgc program provides a user interface for setting various GC
components. Pressing the "Run" button causes these results to be displayed in the large
drawing window on the right. Timing information is displayed in the window immediately
below.
The items in the upper left hand window work as follows:
Function - specify the logical function with which primitives will drawn. The most usual
setting is "set", i.e. simply to render pixels without regard to what has been drawn
before.
LineStyle - specify whether lines should be drawn solid in foreground, dashed in
foreground or alternating foreground and background.
CapStyle - specify the appearance of the ends of a line.
JoinStyle - specify the appearance of joints between consecutive lines drawn within a
single graphics primitive.
FillStyle - specify whether lines, text and fill requests are solid, tiled with a pixmap
or stippled.
FillRule - specifies the rule used to fill polygons. The EvenOdd rule means that if areas
overlap an odd number of times, they are not drawn. Winding rule means that overlapping
areas are always filled, regardless of how many times they overlap.
ArcMode - specifies the rule for filling of arcs. The boundary of the arc is either a
Chord or two radii.
planemask - specifies which planes of the drawing window are modified. By default, all
planes are modified.
dashlist - specifies a pattern to be used when drawing dashed lines.
Line Width - specifies the width in pixels of lines to be drawn. Zero means to draw using
the server's fastest algorithm with a line width of one pixel.
Font - specifies the font to be used for text primitives.
Foreground and Background - specify the pixel values to be applied when drawing
primitives. The Foreground value is used as the pixel value for set bits in the source in
all primitives. The Background value is used as the pixel value for unset bits in the
source when using Copy Plane, drawing lines with LineStyle of DoubleDash and filling with
FillStyle of OpaqueStippled.
Percentage of Test - scrollbar permits specifying only a percentage of the test to be run.
The number at the left indicates the current setting, which defaults to 100%.
The window labeled "Test" permits choice of one a number of graphics primitive tests,
including Points, Segments, Lines, Arcs and Filled Arcs, 8-bit Text and Image Text,
Rectangles and Filled Rectangles, Image draws, as well as Copy Plane and Copy Area.
The window to the right of this has buttons which permit record/playback of the primitives
rendered.
OPTIONS
Xgc accepts all of the standard X Toolkit command line options.
X DEFAULTS
This program accepts the usual defaults for toolkit applications.
ENVIRONMENT
DISPLAY to get the default host and display number.
XENVIRONMENT
to get the name of a resource file that overrides the global resources stored in
the RESOURCE_MANAGER property.
