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.

SEE ALSO

       X(7)

BUGS

       This  program isn't really finished yet, but it probably never will be, since it only demonstrates the original X11 core protocol rendering
       operations, which few modern programs use anymore.

XLOGO(1)						      General Commands Manual							  XLOGO(1)

NAME

       xlogo - X Window System logo

SYNOPSIS

       xlogo [-toolkitoption ...]

DESCRIPTION

       The xlogo program displays the X Window System logo.

OPTIONS

       Xlogo accepts all of the standard X Toolkit command line options, as well as the following:

       -render This option indicates that the logo should be drawn with anti-aliased edges using the RENDER extension.

       -sharp  If -render is also specified, this forces the edges to be rendered in sharp mode, (ie. 1-bit alpha channel).

       -shape  This option indicates that the logo window should be shaped rather than rectangular.

RESOURCES

       The  default width and the default height are each 100 pixels.  This program uses the Logo widget in the Athena widget set.  It understands
       all of the Simple widget resource names and classes as well as:

       foreground (class Foreground)
	       Specifies the color for the logo.  The default is depends on whether reverseVideo is specified.	If reverseVideo is  specified  the
	       default is XtDefaultForeground, otherwise the default is XtDefaultBackground.

       shapeWindow (class ShapeWindow)
	       Specifies that the window is shaped to the X logo.  The default is False.

WIDGETS

       In  order  to specify resources, it is useful to know the hierarchy of the widgets which compose xlogo.	In the notation below, indentation
       indicates hierarchical structure.  The widget class name is given first, followed by the widget instance name.

       XLogo  xlogo
	    Logo  xlogo

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.

FILES

       /etc/X11/app-defaults/XLogo
	      specifies required resources

SEE ALSO

       X(7), xrdb(1)

AUTHORS

       Ollie Jones of Apollo Computer and Jim Fulton of the MIT X Consortium wrote the logo graphics routine, based on a graphic design  by  Danny
       Chong and Ross Chapman of Apollo Computer.
