NAME
     rendercheck - simple tests of the X Render extension.

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

DESCRIPTION
     rendercheck  is a set of simple tests of the X Render extension.  It is de-
     signed for authors of Render implementations in X Servers.

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

     -i|--iter iterations
	    Specifies the number of times to repeat each operation  before  sam-
	    pling  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 choices.

     --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 for-
	    mats listed in  the  server-supported  format  list  are  available.
	    Names must be separated by commas and have no spaces.

     -o|--ops
	    Enables only a specific subset of the Render operators.

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

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

BUGS
     Several  limitations  are	documented  in	the  TODO  file accompanying the
     source.  Please report any further bugs you find  to  http://bugs.freedesk-
     top.org/.
