   rendercheck [-d|--display display] [-i|--iter] [--sync] [-t|--tests test1,test2,test3,...] [-o|--ops op1,op2,op3,...]
   [-v|--verbose] [--minimalrendering]


   rendercheck  is a set of simple tests of the X Render extension.  It is
   designed for authors of Render implementations in X Servers.


   -d|--display display
          Specifies the display to test against.

   -i|--iter iterations
          Specifies the number of times to repeat  each  operation  before
          sampling   results.   Some  X  Servers  may  behave  differently
          (hardware vs software rendering paths) depending on the previous
          operations  done,  so this may be used to influence the server's

   --sync Enables synchronous xlib operation, for debugging.

   -t|--tests test1,test2,test3...
          Enables only a specific subset  of  the  possible  tests.   Test
          names   include   fill,  dcoords,  scoords,  mcoords,  tscoords,
          tmcoords,  blend,  composite,  cacomposite,  gradients,  repeat,
          triangles,  and  bug7366.  Names must be separated by commas and
          have no spaces.

   -f|--formats format1,format2,format3...
          Enables only a specific subset of the  possible  formats.   Only
          formats   listed   in   the  server-supported  format  list  are
          available.  Names must  be  separated  by  commas  and  have  no

          Enables only a specific subset of the Render operators.

          Enables  verbose  printing  of  information  on  tests  run, and
          successes and failures.

          Disables copying of offscreen destinations to the window,  which
          is on by default to provide the user with visual feedback.


   Several  limitations  are  documented in the TODO file accompanying the
   source.    Please   report   any   further    bugs    you    find    to
