NAME
xieperf - XIE server extension test and demo program
SYNTAX
xieperf [-option ...]
DESCRIPTION
The xieperf program is based upon R5 x11perf(1) , and
while not entirely comprehensive in its coverage of the
XIE protocol (see BUGS, below), it is intended to be use-
ful in the evaluation of XIE implementations in the areas
of protocol adherance and performance. The xieperf pro-
gram includes tests which execute each of the protocol
requests and photoflo elements specified by revision 5.0
of the XIE protocol. In addition, xieperf provides a set
of tests which can be used to validate the detection and
transmission of XIE protocol request errors, such as Flo-
Match, FloValue, and so forth. Finally, xieperf provides a
customizable demonstration program for XIE.
A test is made up of three components executed in sequence
- an initialization function, a test function, and an end
function. The initialization function is responsible for
allocating and populating test resources, such as pho-
tomaps and LUTs, and for creating a stored photoflo which
will be executed by the test function. The test function,
in most cases, simply executes the stored photoflo for a
specified number of repetitions. The end function, which
is called following the test function, is used primarily
to destroy any non-cachable server resources used by the
test, and to free any memory which was dynamically allo-
cated by the client. Some tests, such as -modify1, -await,
-abort, and -redefine, perform additional steps within the
test function inner loop, as required by the element being
tested, or in an attempt to make the test more visually
appealing.
Evaluating the performance of individual XIE elements is
not as simple as measuring Core X drawing times. The XIE
protocol requires elements to be embedded within photoflos
in order to be exercised, and the minimum possible
photoflo size is two. This implies that it is impossible
to measure performance of a single element in isolation -
the time it takes to run the flo depends on what other
elements exist in the flo. Extrapolating performance of a
single elment (or technique) in a flo must be done care-
fully, on a case-by-case basis, since in general measured
element performance depends on input image size, data
type, and other factors, all of which can be influenced
by upstream flo elements. Note further that the number
and type of elements in a flo can be influenced by the
visuals available on the display, so even flo-flo compar-
isons on machines with different visuals must be done with
caution.
X Version 11 Release 6.3 1
xieperf(1) xieperf(1)
Many test labels contain an abbreviated pipeline descrip-
tion. For instance. IP/IL/P/ED indicates ImportPhotomap,
ImportLUT, Point, and ExportDrawable. Pipelines ending in
ED (ExportDrawable) often include hidden elements such as
BandExtract, ConvertToIndex, Dither, or Point to match the
flo output to the screen visual. Pipelines ending in EP
(ExportPhotomap) will result in a blank window.
xieperf is compatible with x11perfcomp(1), which is used
to compare the outputs of different xieperf and x11perf
runs in a nice, tabular format. In xieperf you will need
to use the -labels option (see OPTIONS, below), and pro-
vide the resulting labels file to x11perfcomp(1) to obtain
correct output. See the x11perfcomp(1) man pages for more
details on this.
OPTIONS
xieperf accepts the options listed below:
-display host:dpy
Specifies which display to use.
-images <path>
Normally, xieperf references image files
located in the directory ``images'', which
xieperf assumes is located in your current
directory. If the ``images'' directory is
not in your current directory, or the file
has been renamed, use this option to specify
its location.
-timeout <s> Some tests require the reception of an event
such as FloNotify to continue, and may cause
xieperf to hang should these events not be
received. This option allows the user to
specify a timeout value which, if exceeded,
will cause xieperf to give up waiting for an
event, and continue on with the next test in
sequence. Should an event timeout, a warn-
ing message will be printed to stderr. The
default timeout value is 60 seconds.
-sync Runs the tests in synchronous mode.
-script <file>
Using this option gives the user the ability
to run a subset of the available tests and
control the number of times the tests are
executed on an individual basis. This is
thought to be especially useful for those
running xieperf for demonstration purposes.
Using this option causes xieperf to read
commands specified in a script file, or from
stdin if <file> is ``-''. Tests are
X Version 11 Release 6.3 2
xieperf(1) xieperf(1)
specified by newline-terminated input lines
of the form "command [-reps n ] [ -repeat m
]". Characters following and including "#"
are treated as comments. See the -mkscript
option.
-repeat <n> Repeats each test n times (by default each
test is run 2 times). This option may be
used in script files also, in which case the
script file -repeat overrides the command
line option.
-time <s> Specifies how long in seconds each test
should be run (default 5 seconds).
-depth <depth>
Use a visual with <depth> planes per pixel
(default is the default visual).
-GrayScale Use a GrayScale visual (default is the
default visual).
-PseudoColor Use a PseudoColor visual (default is the
default visual).
-StaticGray Use a StaticGray visual (default is the
default visual).
-StaticColor Use a StaticColor visual (default is the
default visual).
-TrueColor Use a TrueColor visual (default is the
default visual).
-DirectColor Use a DirectColor visual (default is the
default visual).
-WMSafe If xieperf must be run in a window manager
environment, use this flag to make xieperf
aware of this. If specified, xieperf will
create a window, identical to the size of
the root window, and all further windows
created by xieperf will be transient popup
children of this window. If this flag is
omitted, xieperf will set the override_redi-
rect attribute of all windows to ``True''
and will also do evil things such as calling
XInstallColormap. Using this option will
cause the window manager to (hopefully) obey
window geometry hints specified by xieperf
-showtechs Display a comprehensive list of techniques,
by category, indicating which of the tech-
niques are supported by the XIE server.
X Version 11 Release 6.3 3
xieperf(1) xieperf(1)
-showlabels Print test label to screen prior to calling
any of the test code. This allows the user
to know which test is executing in case the
test hangs for some reason.
-showevents Be verbose when running event and error
tests. Also, can be used to catch and dis-
play information on any signals received
during execution of xieperf that the error
events received by xieperf are valid the
first time the tests are executed on a new
platform.
-events Run tests which test for event generation.
-errors Run tests which test for error event genera-
tion.
-loCal Skip test calibration. This may be used when
running xieperf in situations where execu-
tion timing is not important. Execution
times will not be reported by xieperf when
this option is enabled. The inner loop
repeat count, additionally, is set to a
value of 5 (but can be overridden by the
-reps option).
-all Runs all tests. This may take a while,
depending on the speed of your machine, and
its floating point capabilities. This option
is ignored if a script file is used.
-tests Generate a list of the available tests for
the xieperf program. In x11perf , this list
is normally displayed in the usage state-
ment. It was yanked from the usage of
xieperf because it was too lengthy.
-mkscript Generate a script file suitable for use with
the script option. If -repeat or -reps are
also specified, they will be automatically
placed at the end of each command in the
script. The script is generated to stderr.
See the -script command, above.
-cache <n> Most test flos utilize a photomap resource
for a source. A photomap cache of up to n
entries is controlled by xieperf to avoid
having to constantly reload these images
during test initialization. The default
cache size is 4. If a value less than the
default is specified, the cache size will be
set to the default.
X Version 11 Release 6.3 4
xieperf(1) xieperf(1)
-labels Generates just the descriptive labels for
each test specified. Use -all or -range to
specify which tests are included. See
x11perfcomp(1) for more details.
-DIS Pretend we are running xieperf while con-
nected to a DIS-only capable implementation
of XIE. This will cause xieperf to execute
those tests which only use protocol requests
found in the DIS subset of XIE, and bypass
those which are not DIS compatible. If
xieperf detects a DIS server, it will do
this automatically, and this option is
ignored. Use -all or -range to specify the
initial range of tests.
-range <test1>[,<test2>]
Runs all the tests starting from the speci-
fied name test1 until the name test2,
including both the specified tests. Some
tests, like the event and error tests, also
require the -errors or -events options to
specified. This option is ignored if a
script it used.
-reps <n> Fix the inner loop repetitions to n. This
indicates how many time the photoflo will be
executed each time the test is run. This
option is overridden on a per-test basis if
specified in a script. Typically, xieperf
determines the ideal number of reps during
each test's calibration period.
-ImportObscuredEvent through -ExportAvailable
Test generation of events. Requires -events
flag.
-BadValue through -FloValueError
Test generation of errors. Requires -errors
flag. -ColorList Create and destroy Col-
orList resource test.
-LUT Create and destroy LUT resource test.
-Photomap Create and destroy Photomap resource test.
-ROI Create and destroy ROI resource test.
-Photospace Create and destroy Photospace test.
-Photoflo Create and destroy Photoflo test.
-QueryPhotomap
Query Photomap resource test.
X Version 11 Release 6.3 5
xieperf(1) xieperf(1)
-QueryColorList
Query ColorList resource test.
-QueryTechniquesDefault through -QueryTechniquesWhiteAd-
just
Query techniques as specified by test name.
-QueryPhotoflo
Query photoflo test.
-PurgeColorList
PurgeColorList test.
-Abort This tests creates a photoflo which is
started and blocks for data provided by Put-
ClientData(). Instead of sending the data,
the test uses XieAbort() to stop the
photoflo, and then waits for PhotofloDone
event to be send by the server. If the test
times out waiting for the event, a error
message is sent to stderr.
-Await This test creates a flo of the form Import-
ClientLUT -> ExportLUT, and starts the flo
executing. xieperf then forks, and the
child process streams the LUT data to the
flo using PutClientData, while the parent
blocks in XieAwait. If the flo successfully
finishes, XieAwait will return and the flo
state, after query, will indicate that it
has completed. If XieAwait does not complete
naturally, or after return from XieAwait the
flo is still active, an error is reported to
stderr. Note, on a really slow machine, it
is possible that XieAwait will return before
the flo has a chance to finish. In this
case, use the -timeout option to increase
the timeout for this test.
-importclientlut1
ImportClientLUT -> ExportLUT test.
-importclientphoto1 through -importclientphoto9
Flos of the form ImportClientPhoto ->
ExportPhotomap using various decode tech-
niques, e.g. G32D, TIFF2, Uncom-
pressedTriple, and so forth.
-importclientroi1
ImportClientROI with 10 rectangles.
-importclientroi2
ImportClientROI with 100 rectangles.
X Version 11 Release 6.3 6

-encodephoto1 through -encodephoto14
Flos of the form ImportPhotomap -> Export-
Photomap using various encode techniques,
e.g. G32D, TIFF2, UncompressedTriple, and so
forth. Original encoding is shown in left
window, image after encoding is shown in
right window.
-encodeclientphoto1 through -encodeclientphoto11
Two flos, one of the form ImportPhotomap ->
ExportClientPhoto, and the other of the form
ImportClientPhoto -> ExportPhotomap, where
ExportClientPhoto in the first flo uses var-
ious encode techniques, e.g. G32D, TIFF2,
UncompressedTriple, and so forth. The image
before encoding is displayed in the left
window, while the right window shows the
image which was encoded in the first flo and
read back in the second flo.
-exportclientlut1
ExportClientLUT test. LUT is displayed in a
histogram window.
-exportclientroi1
ExportClientROI test, 10 ROIs. The ROIs
which are sent to the server are represented
by the filled rectangles. The ROIs which are
received back from the server by the client
are drawn as white bordered non-filled rect-
angles. The resulting output illustrates
how the server combined the rectangles sent
to it.
-exportclientroi2
Same as exportclientroi1, except using 100
rectangles.
-exportclienthistogram1 through -exportclienthistogram4
ExportClientHistogram tests using various
images. The histogram is displayed in a win-
dow which overlaps the image.
-exportclienthistogramroi1 through -exportclienthistogram-
roi4
Same as the ExportClientHistogram test, but
using a ROI to identify the area of inter-
est.
-exportclienthistogramcplane1 through -exportclienthis-
togramc- plane4
Same as the ExportClientHistogram test, but
using a Control Plane to identify the area
of interest.

-funnyencode1 through -funnyencode8
These tests are design to perform limited
exercising of XIE's capability of dealing
with various encodings of flo source data.
The test init function obtains a photomap
using ICP -> EP. A series of independent
permanent flo pairs, one of the form IP ->
EP, and the other of the basic form IP ->
ED, are constructed. The encoding parameters
for the ExportPhotomap (EP) element in the
first flo are derived from test configura-
tion. The number of flo pairs created is
also dependent upon test configuration. The
tests can be configured so that the test
init function will constrain the input pho-
tomap to a specified number of levels, on a
per-band basis, so that word-sized and quad-
sized pixels are passed through the flos.
X Version 11 Release 6.3 13
xieperf(1) xieperf(1)
Some tests below take advantage of this. See
tests.c for test configuration, and hints on
how to add similar tests.
-point1 through -point3
Simple Point element tests. Drawable desti-
nation. -pointroi1 Simple Point element
test which uses ROIs. Drawable destination.
-pointcplane1 Simple Point element test which uses a Con-
trol Plane. Drawable destination.
-pointphoto1 Simple Point element test. Photomap destina-
tion.
-pointroiphoto1
Simple Point element test which uses a ROIs.
Photomap destination.
-pointcplanephoto1
Simple Point element test which uses a Con-
trol Plane. Photomap destination.
-redefine Two flographs are created which are the same
in structure, expect for the x and y offsets
specified for the ExportDrawable flo ele-
ments. The test init function creates a
photoflo based upon one of the two flo-
graphs. The inner loop of the test function
uses XieRedefinePhotoflo() to alternate
between each of the flographs. Make sure
that your ineer loop reps are 2 or greater
in order to exercise this test fully (see
-reps).
-modify1 Test XieModifyPhotoflo() by adjust ROI off-
sets and size.
-modify2 Test XieModifyPhotoflo() by changing the LUT
input to a Point element.
-modify3 Test XieModifyPhotoflo() by changing Export-
Drawable x and y offsets.
-modify4 This test creates a rather long flo of
arithmetic elements, each which does nothing
more than add 1 to a small image. The test
init function scales the input photomap. The
ExportDrawable x and y offset is modified
randomly during each iteration of the test
function inner loop.
-modify5 This test creates a rather long flo of
arithmetic elements, each which does nothing
X Version 11 Release 6.3 14
xieperf(1) xieperf(1)
more than add 1 to a large image. Each rep,
the Geometry and ExportDrawable elements at
the end of the flo are modifed to crop a
small piece of the input into its appropri-
ate place in the larger image.
-rgb1 through -rgb16
These tests all basically take an Uncom-
pressedTriple image as input, send it to
ConvertFromRGB which converts the image to
some configured colorspace, and then send
the converted image on to ConvertToRGB prior
to display. The original image is displayed
in the lefthand window, and the image which
has passed through the flo is shown in the
righthand window. The goal of these test is
to show that ConvertFromRGB -> ConvertToRGB
is lossless.
-converttoindexpixel
ConvertToIndex test, TripleBand BandByPixel.
-converttoindexplane
ConvertToIndex test, TripleBand BandByPlane.
-convertfromindex
The test init function uses a flo containing
ConvertToIndex to display an image in the
left window. The test function uses this
drawable as input to a flo which does Con-
vertFromIndex -> ConvertToIndex and sends
the resulting image to the right window. The
result should be lossless.
-complex A somewhat large flo which uses control
planes, LUTs, Point, PasteUp, Logical, Con-
strain, Dither, Geometry, MatchHistogram,
BandCombine, and BandSelect elements. See
the Postscript file ''complex.ps'' for a
rendition of the photoflo which is executed.
X DEFAULTS
There are no X defaults used by this program.

X(1), x11perf(1), x11perfcomp(1)
BUGS
There should be a IMAGES environment variable to augment
the -images option.
Many tests only scratch the surface of possible test
cases. Some of the options available for certain flo ele-
ments are either inadequately tested, or ignored
X Version 11 Release 6.3 15
xieperf(1) xieperf(1)
altogether. There are insufficent tests for bitonal,
large pixel, or triple band tests.
Some of the test names are inconsistently cased, e.g.
-Abort and -dither1.
Some tests are hopelessly slow when run against machines
with slow FPUs.
Bitonal images are for the most part displayed using the
ExportDrawable flo element, however, ExportDrawablePlane
would be a better choice.
