|
| |
_funnyencode1 through
|
These tests are designed 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 con-structed. The encoding parameters for
the ExportPhotomap (EP) element in the first flo are derived from
test configuration. 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
photomap to a specified number of levels, on a per band basis, so
that word-sized and quad-sized pixels are passed through the
flos. Some tests below take advantage of this. See
tests.c for test configuration, and hints on how to add similar tests.

| |
_redefine
|
Two flographs are created that are the same in
structure, xinetd except for the x and y offsets specified for the
ExportDrawable flo elements. The test init function creates
a photoflo based upon one of the two flographs. The
inner loop of the test function uses
XieRedefinePhotoflo() to alternate between each of the flographs. Make sure
that your inner loop reps are 2 or greater in order to
exercise this test fully (see -reps).
| |
_modify1
|
Test XieModifyPhotoflo() by adjusting ROI offsets and size.
| |
_modify2
|
Test XieModifyPhotoflo() by changing the LUT input to
a Point element.
| |
_modify3
|
Test XieModifyPhotoflo() by changing
ExportDrawable x and y offsets.
| |
_modify4
|
This test creates a rather long flo of arithmetic
elements, each of 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 of which does nothing more than add
1 to a large image. Each rep, the Geometry and
ExportDrawable elements at the end of the flo are modified to crop a small piece of
the input into its appropriate place in the larger image.
| |
_rgb1 through _rgb16
|
These tests all basically take an
UncompressedTriple 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 left-hand window, and the
image that has passed through the flo is shown in the
right-hand window. The goal of these test is to show
that ConvertFromRGB -> ConvertToRGB is lossless.
| |
_converttoindexpixel
|
ConvertToIndex test,
TripleBand BandByPixel.
| |
_converttoindexplane
|
ConvertToIndex test,
TripleBand BandByPlane.
|
Page 654
|
_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 that does
ConvertFromIndex -> ConvertToIndex and sends the resulting image to the
right window. The result should be lossless.
| |
_complex
|
A somewhat large flo that uses control planes, LUTs,
Point, PasteUp, Logical, Constrain, Dither,
Geometry, MatchHistogram, BandCombine, and
BandSelect elements. See the Postscript file
complex.ps for a rendition of the photoflo that is executed.

X DEFAULTS
There are no X defaults used by this program.

BUGS
There should be an 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 elements
are either inadequately tested, or ignored altogether. There are insufficient tests for bitonal, large pixel, or triple
band tests.
Some of the test names are inconsistently cased, for example,
-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.
