BitsPlusImagingPipelineTest([whichScreen][,plotdiffs=0][, forcesuccess=0])
Tests correct function of Mono++ and Color++ mode with imaging pipeline...
This test script needs to be run once after each graphics card or
graphics driver or Psychtoolbox upgrade.
This test tests if the Psychtoolbox image processing pipeline is capable
to correctly convert a high dynamic range image for the Cambridge
Research Systems Bits++ box for Mono++ and Color++ mode.
It does so by generating a test stimulus, converting it into a Bits++
image via the Matlab
BitsPlusPlus toolbox and by use of the imaging
pipeline. Then it reads back and compares the conversion results of both
to verify that the imaging pipeline produces exactly the same results
as the Matlab routines.
If the results are the same, it will write some info file to the
filesystem to confirm this test was successfully run.
whichScreen =
Screen id of display to test on. Will be the secondardy
display if none provided.
plotdiffs = If set to one, plot diagnostic difference images, if any
differences are detected. By default no such images are plotted. No
images will be plotted if no differences exist.
forcesuccess = Set this to one if you want to force the test to succeed,
despite detected errors, ie., if you want the GPU
conversion to be used. Only use this if you really know
what you are doing!
Please note that this test script can only test if the correct output to
your systems framebuffer is generated by Psychtoolbox. It can't detect if
the Bits++ box itself is working correctly with this data. Only visual
inspection and a photometer/colorimeter test can really tell you if the
whole system is working correctly!
