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.
