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 designed 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  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 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 formats 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.
